As utility bills rise, renters are looking at solar too — but usually not in the same way homeowners do. Instead of rooftop systems, many are weighing portable equipment that can lower electricity use without being permanently attached to the property.
That issue came up when a tenant asked for advice on Reddit about whether a move-friendly setup could support an air conditioner and a home office while still being easy to bring to a new place later.
In a post on Reddit, the renter said higher power costs were pushing them to explore solar, but that a permanent grid-connected installation was not an option because they do not own their house.
They specifically mentioned the EcoFlow DELTA Pro/Plus and asked, “Do you guys have any recommendations for a setup that would work for renters?”
Rather than trying to supply the whole home, the poster said they mainly wanted to cover a smaller set of needs: an AC unit, a desktop PC, a laptop, and a display.
Commenters suggested portable solar packages built around panels and an inverter, with placement options such as a balcony or a ground setup that would not require modifying the rental and could be taken along after a move.

For many households, rooftop solar is one of the clearest ways to lower monthly energy costs, but renters are often shut out of that option.
Even when a landlord is open to the idea, a permanent installation can involve approvals, wiring work, and costs that may not make sense for someone planning to relocate.
Portable solar changes that equation. Instead of spending money on equipment tied to a property they do not own, renters can invest in panels and storage they can keep using after a move.
The tradeoff, however, is scale.
A portable setup is far less likely to replace all of a home’s grid electricity, especially if an air conditioner is part of the load. Still, using solar to cover daytime office equipment — and some cooling — can help trim bills by reducing the amount of electricity pulled from the grid during expensive usage periods.
The savings are less about going fully off-grid and more about chipping away at recurring monthly costs while avoiding the sunk expense of improving someone else’s house.
The first step is figuring out how much electricity the target devices actually use.
A desktop, laptop, and monitor may be manageable for a portable system, while an air conditioner can quickly push up the required battery size and panel output.
That is why a smaller, more economical setup may still be worthwhile if the goal is to reduce the bill rather than to provide whole-home backup. Covering the workstation first can deliver more predictable savings than overspending on a large battery meant to do everything.
Shoppers also need to consider where panels can safely go. A balcony, patio, yard, or other temporary placement may work, but lease terms, building rules, and sunlight exposure will all affect performance and practicality.
The appeal is portability, flexibility, and at least some relief from the monthly bill.

According to the latest IndexBox report on the global Aluminum Solar Mounting Rails market, the market enters 2026 with broader demand fundamentals, more disciplined procurement behavior, and a more regionally diversified supply architecture.
The global aluminum solar mounting rails market is entering a prolonged expansion phase, with demand projected to grow at a compound annual rate of 8-12% between 2026 and 2035. This trajectory is anchored in the accelerating build-out of solar photovoltaic capacity worldwide, which is expected to surpass 400 GW of annual additions by the early 2030s. Aluminum rails, as the structural backbone of rooftop and ground-mount PV systems, account for an estimated 20-25% of balance-of-system costs in utility-scale projects, making their supply chain performance a critical determinant of project economics.
The market is shaped by the interplay of three forces: the relentless cost-down pressure in solar project development, the shift toward higher-strength and lighter aluminum alloys that reduce material intensity, and the ongoing geographic reconfiguration of extrusion capacity as North America and Europe seek to lower their dependence on Chinese imports. Import reliance remains pronounced, with markets outside China sourcing 40-60% of their rail supply from Chinese extruded aluminum, exposing buyers to tariff volatility and lead-time variability.
At the same time, pre-coated and corrosion-resistant rail variants are gaining share in coastal and desert installations, now representing 15-20% of global volume and growing at a 10-12% CAGR. This report provides a data-driven assessment of market size, demand structure, supply capability, trade flows, pricing, and competitive dynamics, with a forecast horizon extending to 2035.
The baseline scenario for the aluminum solar mounting rails market points to sustained growth through 2035, underpinned by the global energy transition and the industrialization of solar deployment. Annual solar PV capacity additions are expected to exceed 400 GW by the early 2030s, creating a corresponding pull for mounting hardware. Aluminum rails benefit from their favorable strength-to-weight ratio, corrosion resistance, and recyclability, which keep them the material of choice for most mounting applications despite competition from steel and composite alternatives.
The market is also benefiting from a structural shift toward higher-strength alloys such as 6005A and 6063, which allow thinner wall sections and reduced material usage per mounting point, lowering total installed cost. Pre-coated and corrosion-resistant variants are expanding their share, particularly in aggressive environments, and are projected to grow at a 10-12% CAGR. On the supply side, regional extrusion capacity expansions in the United States and the European Union are underway, but these will take 3-5 years to meaningfully alter trade flows. In the interim, import dependence on Chinese extrusions remains high, with tariff and anti-dumping measures creating uncertainty.
Aluminum ingot price volatility, with LME prices fluctuating between USD 2,200 and USD 3,000 per metric tonne, continues to squeeze manufacturer margins and complicate long-term project pricing. Lead times of 4-8 weeks for die qualification and surface treatment constrain the ability to respond to demand surges. Despite these challenges, the market is expected to grow at a CAGR of 8-12% from 2026 to 2035, with the market index reaching 200-300 by 2035 relative to 2025.

Kyrgyzstan launches 1st large solar power plant with China's support, ending rolling blackouts – bastillepost.com

Font Size
China
Kyrgyzstan has launched its first large-scale solar power plant, bringing an end to the long-standing issue of rolling blackouts for local residents — thanks in large part to support from China.
Built by a Chinese company and operational since December 2025, the 100-megawatt facility, the country’s first solar power plant, is located in the Kemin District of the Chui Region. With an annual generating capacity of 200 million kilowatt-hours, it provides a stable, uninterrupted electricity supply to surrounding settlements and cities.
Thanks to its automated systems, the plant requires only a small maintenance team to run — a major step forward for the region’s energy infrastructure.
Previously subjected to frequent power rationing, local residents are now experiencing a more stable electricity supply.
“We are already starting to forget about rolling blackouts. The power supply is so much more stable now. With a normal electricity supply, of course, our standard of living and quality of life have really improved,” said Abel Chukubayev, a local resident.
“Kyrgyzstan has resources, and China has technology. This is a model of win-win cooperation,” said Ma Wenjun, head of the power plant.
Kyrgyzstan launches 1st large solar power plant with China’s support, ending rolling blackouts
Chinese President Xi Jinping arrived in Bishkek, the capital city of Kyrgyzstan, on Sunday afternoon for the Shanghai Cooperation Organization (SCO) Summit 2026 and a state visit to Kyrgyzstan at the invitation of Kyrgyz President Sadyr Japarov.
Upon arriving at the Manas International Airport, Xi and his wife, Peng Liyuan, were warmly welcomed by Japarov and his wife, Aigul Japarova.
Xi and Peng were treated to Kyrgyz delicacies and accorded a greeting steeped in the nation’s traditions by local women.
Guards of honor lined up on both sides of a red carpet to salute the Chinese leader.
Both president and their spouses watched Kyrgyz cultural performances and displays, and listened to Chinese songs performed by local youngsters.
In a written speech, Xi extended sincere greetings and best wishes to Japarov and the people of Kyrgyzstan on behalf of the Chinese government and people.
Noting that China and Kyrgyzstan share a time-honored traditional friendship, Xi said that the majestic Tianshan Mountains stands as witnesses to the millennia of friendly exchanges between their peoples.
Over the 34 years since the establishment of diplomatic relations, the China-Kyrgyzstan relationship has withstood the test of a changing international landscape, maintained sound and steady development throughout, and reached the high level of a comprehensive strategic partnership for a new era.
In recent years, bilateral trade volume and people-to-people exchanges have reached new highs, Xi said, noting that major projects including the China-Kyrgyzstan-Uzbekistan railway have been successfully implemented, and the tangible results of mutually beneficial cooperation have broadly benefited the two peoples.
Xi said that during the visit he will have in-depth exchanges of views with Japarov on China-Kyrgyzstan relations, cooperation in various fields between the two countries, and international and regional issues of common concern, and draw a new blueprint for building a China-Kyrgyzstan community with a shared future.
Xi said he looks forward to attending the SCO Bishkek Summit, working with all parties to revisit the 25-year development experience of the SCO, jointly discuss cooperation plans, create the future of the organization, and promote the continuous new development of the organization.
Xi’s entourage also includes Cai Qi, a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee and director of the General Office of the CPC Central Committee, and Wang Yi, a member of the Political Bureau of the CPC Central Committee and Chinese foreign minister.

Divers scraped 18 floats from the North Sea’s first offshore solar farm and found 47 kinds of marine life living on them, including 12 species that did not belong there – Energies Media

Energies Media
In the Dutch North Sea, 47 species colonized 18 offshore solar floats, including 12 non-native ones.
Available land for renewable energy growth is becoming scarcer across the world.
To meet both global power demand and climate targets, the green transition is rapidly increasing offshore.
However, the addition of more new artificial structures in marine environments is triggering ecological changes.
Will there be consequences following these quick marine transformations, and what will they be?
Global electricity consumption is projected to double by 2050.
Digitization and industrial electrification are the primary drivers of this increase.
This complicates the world’s attempts to meet ambitious climate mandates.
Presently, power usage outpaces the rate at which new green generation is deployed.
As a result, grids worldwide are struggling to prevent electricity fluctuations and potential blackouts.
Utilities continuously rely on fossil fuels to stabilize grids, resulting in high emissions.
To break this cycle, clean power generation must rapidly scale.
However, the leading sources, wind and solar, require vast land for installation.
Suitable land is becoming scarce globally, creating competition with other sectors and onshore ecosystems.
Now, nations such as the Netherlands are addressing these spatial limitations by turning to offshore infrastructure.
While most are deploying offshore turbines, the Dutch North Sea has become a testing ground for offshore solar panels.
The Dutch are aiming for gigawatt-scale integration in the next decade.
While floating solar may not be new, floating arrays have been limited to reservoirs and lakes.
Naturally, concerns followed about the impact on natural water bodies onshore.
Consequently, some nations decided to take solar systems to the sea.
In the Dutch North Sea, deploying these floats offers distinct benefits.
Beyond using open-water spaces instead of valuable land, they can also be co-located with existing offshore wind farms.
This co-location saves money, as the systems can share grid connection cables.
Furthermore, the cooler ocean air prevents panel overheating, boosting efficiency.
Additionally, the open sea reflects more sunlight, further increasing output.
However, these large artificial structures over the ocean also raise environmental concerns.
The structures can alter the dynamics of the surface beneath, hence possibly affecting the behavior of marine wildlife.
To investigate potential environmental shifts, researchers examined the North Sea’s first offshore solar project.
Submerged parts of 18 floaters were scraped for samples, revealing surprising findings.
A research team from Wageningen Marine Research conducted the study.
The solar float farm is located at the Offshore Test Site, 7.5 miles off the coast of The Hague.
The quantitative samples enabled the analysis of organisms attached to the structural surfaces.
In total, 47 different species were identified, including 12 non-native ones.
The most abundant group in population numbers was arthropods, more specifically small amphipods. They are of the genus Jassa.
Mollusks accounted for the biggest share of total biomass, especially blue mussels.
Other species in the community included:
The non-native species had higher individual counts than local ones, and contributed less to biomass.
Some of these non-indigenous species included:
The findings demonstrate that offshore floating solar functions similarly to other offshore structures.
More specifically, they function as ecological drivers that facilitate species dispersion across the North Sea.
As the need for rapid offshore infrastructure deployment increases, it is vital that developers understand the potential environmental consequences.
Since these solar floats transform into artificial reefs so quickly, further monitoring will be required to determine long-term ecosystem impacts.
Furthermore, without intervention, this rapid biofouling adds significant additional weight to the platforms.
Ultimately, to prevent potential structural damage, developers must learn to maintain these platforms without disrupting wildlife.

East Texas solar farm not connected to data center, residents told at Q&A events – Tyler Morning Telegraph

Published 5:45 am Sunday, August 30, 2026
By Lia Portillo
JEFFERSON – Marion County residents heard details this week at community meet-and-greet events about a planned 2,000-acre solar farm, with some attendees saying their fears about the project being connected to a data center were put to rest.
Pathway Power, the company building the $200-million solar farm south of Avinger, held the events Tuesday and Wednesday at the Kellyville Community Center.
Poster boards depicting renderings of the project, pictures of the location and informational posters about the company and of the science behind solar farms were displayed across the room. Representatives of Pathway Power were scattered throughout the community center to answer residents’ questions. 
Shar Parr, who lives near Lake O’ the Pines, asked about the project’s possible impacts on the region’s water resources.
“I have been very involved in fighting to save the water for our region and for our future, for our growth,” she said. 
Parr also asked if the farm is a precursor to a data center. 
“And (the CEO of Pathway Power) said ‘No, absolutely not.’ And I’m quoting him when I say that. And so I was happy to hear that, although skeptical,” she said.
Parr also asked if the solar farm is connected at all with a data center being built in Blanchard, Louisiana, to which she was told no.
She said Pathway Power’s CEO told her the solar farm’s battery storage system would require some water, but that it was “an evaporative cooling system, and he referred to it as a system that would be closed.”
Closed-loop systems require significantly less water than traditional open-loop systems used in data centers.
Given the proximity of Johnson Creek Reservoir to Lake O’ the Pines, Parr asked if Pathway Power intends to place “catchment rows to be able to catch the siltation or runoff during heavy rainfall.” 
She said she was told yes and that the company plans to reseed the area.
Parr said she is still skeptical about this project but appreciated being able to ask questions.
“I think that that’s an important move forward, is being able to sit down at the table and say, ‘OK, here’s this, here’s this. We know it’s coming. Now how do we best work together?’” Parr said. “Because we’re not going to stop. I mean, I’m sure that my grandmother at some point told somebody, ‘Don’t ever go to the moon!’ And so I don’t want to be that person. But I also want to be responsible, because I owe it to the younger generation to do that.”
Jimmie Alford said he is interested in the project as the solar farm would be 30 feet from his daughter’s house.
He wanted to talk to Pathway Power representatives to ask what to do in case of an emergency.
“I was trying to find out what we needed to do as a fire department in case (of a fire from the battery system),” said Alford, who is Avinger’s assistant fire chief. “Well, do nothing. We’re not going in there and messing with it.”
Jean Noe, who moved to the Johnson Creek Reservoir area six years ago, said she attended the meet-and-greet to learn what is true and not from information she read online.
“There was so much information flying around that I didn’t know whether it was the truth or rumor,” she said. “(The event) put a lot of those concerns to rest because it’s not at this point in time what anybody thought it was going to be. (Pathway Power officials) insisted they have zero to do with any data centers. They’ve not built data centers or constructed solar for any data centers. They have never partnered with any data centers, and (there’s) nothing in the future plan.
“So, at this point in time, I will believe them. And I think that most everybody’s concern was these data centers coming in. And I mean they’ve kind of put my mind to rest for that to rest for that for right now. We’ll see what the future brings.” 
Hunter Bonner, the chair of the Marion County Republican Party, said this event was “much needed.” He said it was important for Pathway Power to meet its neighbors and learn more about the community.
One of his concerns about the solar farm and its battery system is safety. He said he was able to speak with an expert in batteries who told him that the technology to deal with containment of fires has increased over the years.
“(Pathway Power officials) were also able to answer questions about where the arrays were actually going to be,” Bonner said. “A lot of people think it’s just going to be this one continuous field of solar arrangement, (but) based upon the renderings that they showed, it’s going to be kind of in different areas.”
While he said Pathway Power representatives were very receptive, there is still more information that county commissioners should consider ahead of the company’s tax abatement hearing.
Pathway Power is seeking a tax abatement from Marion County that would reduce the amount of property taxes the company pays over a period of time. The project is expected to generate roughly $13 million in sales and use tax during construction and nearly $58 million in property taxes during the next 35 years. The project has an expected lifespan of 35 to 40 years.
The tax abatement process includes public hearings during Commissioners Court meetings and a vote by commissioners.
“One question I asked him was, ‘At what stage are you with engineering plans?’ And they’re about 30% done with that,” Bonner said. “We really need to see those engineering plans, and I would definitely say that those engineering plans need to be available before the Marion County commissioners even think about having an abatement hearing on this.”
Before attending the meeting, Bonner had tried reaching out to Pathway Power staff and had a hard time getting in touch with someone. It’s something he says he hopes the company works on.
“While I am glad that Pathway came out and did hold the event that they did, they need to be a little bit more visible and certainly more accessible than what they have been recently,” he said.
He also encouraged residents to make their voices heard and reach out to their local party officials and local representatives with concerns or questions. 
Jam Attari, managing partner and founder of Pathway Power, said when he and his team start a large-scale project such as the solar farm, they try to engage with the community.
“There is both short-term and long-term impact, both positive and negative, and we want to make sure the community is aware of what we’re doing on site, and to find different ways where we can support the community,” Attari said. 
Other than hearing about water concerns, Attari said he talked about road disruptions, economic impact to the area and more.
“Certainly, people are concerned with road use and what that impact will be. So we’ll certainly work with the community to make sure that they understand when trucks are moving on to the site and minimizing the disruption caused by construction traffic,” Attari said. “People are concerned about safety. So we want to make sure that we’re bringing the right kind of information to help have people understand at the end of the day, (a) fire is not a concern, any leaching chemicals … just doesn’t happen on power projects like this.”
Attari added that regional business owners have already approached him about being contractors for the solar farm’s construction.
“Part of this outreach is not just to local residents, but I’ve already met with three businesses that operate here locally that will engage in conversations,” he said.  “We’ll see where it goes, but there’s a concrete plant that is very conveniently local, (and) there’s a civil contractor that’s also local. Part of our requirement for folks that will contract to build our project is that they will use local labor and local contracting sources.” 
Construction is expected to start next year with operation slated for late 2028. 
“What we want to be able to do is to communicate (about this project), and what that means for the community,” Attari said. “Both in a real sort of physical way, what’s going to go on during construction and what’s going to go on during operation, and that at the end of the day, our intent is to minimize any disruption while adding a strong impact economically to what we’re doing.”

A new water heater is supposed to solve problems, not create new ones. But for one homeowner, a replacement job instead led to a trip online for a second opinion after several details in the installation raised concerns.
Following the swap from an older natural-gas tankless heater to a Rinnai RE180, the homeowner shared annotated photos on Reddit and asked other users to look over the installation.
“Please point anything out not to code or not aligned with manufacturer recommendations. I circled concerns of mine in red,” the homeowner wrote.
Users pointed to several parts of the setup that they thought warranted a closer look.
One asked, “No issue with the non UV rated pex directly off the tank?” Another wrote, “Biggest issue I see is the use of CPVC pipes (but that seems to have been there all the time, not part of new install).”
For homeowners who can electrify during a replacement, a heat pump water heater may also be worth comparing before signing off on a new gas unit. Depending on the home and the equipment being replaced, that switch can lower utility bills.
Tankless water heaters can reduce wasted energy compared with conventional storage tanks because they heat water on demand, but proper installation is still critical.
PEX that is not rated for UV exposure can degrade in direct sunlight, while CPVC is often criticized for becoming brittle over time.

Want to go solar but not sure who to trust? EnergySage has your back with free and transparent quotes from fully vetted providers in your area.
To get started, just answer a few questions about your home — no phone number required. Within a day or two, EnergySage will email you the best options for your needs, and their expert advisers can help you compare quotes and pick a winner.
Solar panels can save you more than $50k over their 25-year lifespan, and EnergySage can help you save as much as $10k on installation. Which begs the question — isn’t that worth an email or two?
The placement of the unit also drew scrutiny from one commenter, who wrote, “Where do you live bc in Texas all heaters are inside or covered?” The OP later clarified they live in Florida and that the tank and piping are in direct sunlight for about eight hours each day, which led some commenters to express concern about how some of the materials would fare in that radiation over time. 
Gaps where pipes pass through stucco can allow in moisture, pests, and air leaks, potentially leading to additional repair costs later.
If a new water heater installation looks questionable, the next best step is often to ask the contractor for permit information, installation manual references, and a written explanation of the materials used.
Homeowners can also request a municipal inspection or seek a second opinion from another licensed plumber familiar with the brand.
If you are replacing a water heater anyway, it may also be smart to compare electric heat pump models with gas or standard electric options. Companies such as Cala are trying to make that choice more appealing for consumers focused on both comfort and monthly savings.
Its customizable smart heat pump water heaters help homeowners reduce their energy bills by heating water only when needed. Cala systems are designed to store hot water intelligently, helping households avoid unnecessary energy use and better manage demand throughout the day. For shoppers looking for a longer-term bill-cutting upgrade, Cala offers another example of how water heating technology is changing.
“Have some concerns with the recent new install, but don’t know enough about plumbing,” the original poster wrote.
A commenter suggested a straightforward way to address one part of the job: “OP can easily caulk or seal the holes in the stucco.”

As more and more people adopt clean energy upgrades, residents will increasingly inherit solar panels and battery upgrades when purchasing a new home. 
That’s why one homebuyer took to Reddit to seek advice after purchasing a home with a Tesla Solar Roof and Powerwall installed a few years ago. 
The buyer wrote in the r/TeslaSolar subreddit, “I’m buying a home with a Tesla Solar Roof installed by Tesla about 4 years ago.” With limited time to evaluate the property, the buyer wanted advice on checking for unresolved service cases, past repairs, remaining warranty coverage, production performance, and whether a dedicated solar-roof inspection made sense.
Users in the comment section suggested that the buyer should first review the system’s production via the current owner’s Tesla app. That should offer valuable insight into how much the system saves the owner on utility costs. 
A properly functioning solar roof and battery can mean lower monthly utility bills, reduced future energy costs, and the opportunity to avoid the upfront cost of installing a similar system from scratch.
However, if there are inverter issues, failed tiles, leaks, or unresolved service problems, those savings can disappear quickly.

A Tesla Solar Roof is more complicated than a standard roof replacement because it serves as both weather protection and an energy-producing system. That means buyers are not just inheriting shingles — they are also taking on power hardware, software access, warranty paperwork, and service history.
App access can help confirm that the system is operating as expected, while service records can indicate whether the home has experienced roof leaks, tile failures, battery issues, or inverter problems.
A standard home inspector may catch visible roof concerns, but may not be equipped to determine whether solar generation is tracking normally or whether the Powerwall has experienced problems.
If the equipment is in good condition, installing rooftop solar can provide cleaner backup power, reduce reliance on the grid, and yield meaningful electricity savings.
Anyone buying a home with Tesla solar can start by asking the seller to open the Tesla app and show production data and battery information. 
It can also help to request service documents, installation paperwork, and any warranty information explaining what transfers after a home sale. If repairs have been made, buyers should ask what was fixed and whether the issue has stayed resolved.
Reviewing past utility bills can also be helpful. If the home has solar and storage, the billing history should generally show at least some reduction in grid electricity use, depending on household habits and local rates.
And when the technology makes up a major part of the home’s value, bringing in a solar-savvy inspector or roofer may be a smart extra step.

Scientists use AI to invent viruses never seen in nature, fueling hope for medical breakthrough – The Cool Down

If AI can speed up the search for effective phages, it could eventually help physicians target harmful bacteria more precisely.

A study has found artificial intelligence can generate virus designs that do not occur in nature. While that may sound concerning, scientists who advocate for the technology said the new viruses can unlock medical breakthroughs. 
The viruses in question were bacteriophages, meaning they target bacteria rather than people. Even so, outside experts have said the result is a significant sign of how much AI-driven biotechnology is advancing.
According to Smithsonian Magazine, citing research published in Science, the team used the generative AI models Evo 1 and Evo 2 to make new bacteriophages.
After being trained on vast amounts of genetic information, the models were asked to produce phages similar to Phi X-174, a widely studied virus that infects E. coli.
Out of roughly 700,000 candidate designs, the researchers selected 285 to build in the lab. Sixteen of those synthetic phages were able to halt E. coli growth in Petri dishes.
Those 16 AI-made phages also showed promise in later experiments: together, they successfully attacked two antibiotic-resistant E. coli strains. Phi X-174 and a mix of natural phages did not succeed in those same tests.

According to the World Health Organization, bacterial resistance was associated with more than 4.7 million deaths globally in 2021.
In comments to Carl Zimmer at The New York Times, as reported by The Smithsonian Magazine, Patrick Cai, a synthetic biologist at the University of Manchester who was not involved in the study, called it “an important milestone.”
Researchers have long been interested in bacteriophages as a possible way to treat infections that no longer respond to antibiotics. If AI can speed up the search for effective phages, it could eventually help physicians target harmful bacteria more precisely.
That potential benefit comes with a risk. Technology that can create helpful viruses could also be abused if it were directed toward dangerous pathogens.
Isaac Bogoch, an infectious diseases specialist at the University of Toronto who was not involved in the research, told John Power and Erin Hale at Al Jazeera, as quoted by Smithsonian Magazine, that “A.I.-designed viruses could have some potential benefits, such as the creation of targeted bacteriophages that could possibly help us tackle antibiotic-resistant infections in new ways.”
There are technical limitations as well. Tom Ellis, a synthetic genome engineer at Imperial College London who was not involved in the study, told Al Jazeera that the phage used in this research has an extremely small genome, meaning more complex viruses are much harder to design.
According to Smithsonian Magazine, the researchers said they tried to limit the danger by leaving certain genomes out of Evo’s training data, preventing the system from generating viruses that could infect humans, animals, plants, or fungi.
They also said they adopted safety measures beyond what is standard in bacteriophage research and outlined those steps in the paper’s additional materials as a possible biosafety framework for future work.
Another approach could involve using mixed phage therapies instead of relying on a single virus. Study co-author Brian Hie, a computational biologist at Stanford University, said in a statement that pairing genetically distinct phages could make it harder for bacteria to evolve around treatment.
As the technology develops, oversight, screening, and clear limits may need to keep pace.

Getting started with solar panels can be expensive, but one Reddit user shared a do-it-yourself method to keep costs down. 
The homeowner said affordable used photovoltaic panels were not easy to locate through standard local listings.
Facebook Marketplace turned up better options than Craigslist, and paying for delivery only seemed practical when the purchase was large enough to come by the pallet.
Instead of buying dedicated racking, the poster described a temporary mounting option built from free pallets and weighted with ballast already on hand, including bricks, stones, water jugs, or logs.

“You might be curious or be able to learn from my experience…,” they wrote before detailing the low-cost setup.
One commenter in Maryland described buying 18 440-watt panels at $177 each from a local distributor. 
That would bring the panel cost to $3,186 total for 7,920 watts of capacity, or roughly 40 cents per watt before other equipment.
For homeowners considering their options, going solar is one of the best ways to save on home energy costs. You can explore EnergySage to get free solar installation estimates and compare quotes.

Picking up used panels nearby can help buyers avoid high freight charges, and free pallets can cut costs further by replacing purpose-built mounting gear.
This option may be especially attractive for homeowners who want something temporary rather than a permanent installation.
The original poster said pallets add some weight of their own, can hold extra ballast, are widely available, and can be moved without digging posts or attaching hardware to a house. They also noted that screwing 2×4 boards to the side of a pallet can alter the panels’ tilt angle.
That flexibility could make a DIY system easier to test and adjust, though homeowners still need to consider local codes, utility interconnection rules, and safety requirements before attempting anything similar.
💡Go deep on the latest news and trends shaping the residential solar landscape
Shoppers interested in the cheapest route to solar can start by checking local resale listings, nearby distributors, and community sellers before paying for shipped equipment.
It is also wise to inspect panel labels, condition, and output ratings, then confirm what your utility and local building rules allow before installation.
If you want to explore rooftop solar without all the trial and error, EnergySage’s free services can help you quickly narrow down costs. EnergySage’s solar map shows the average cost of a home solar panel system by state, as well as details on local incentives. Together, these resources can help you get the best price for rooftop solar panels.
Adding battery storage to a solar setup is one of the best ways to protect your home during outages, save on energy costs, and rely less on the grid. You can also explore EnergySage for information about home battery storage options, including competitive installation estimates.
As the original poster noted, “pallets are readily available almost everywhere,” and ballast like “bricks, stone, jugs of water, logs” can help “prevent the panel from moving in the wind.”

Solar PV systems: Economically viable and environmentally beneficial on dairy farms – Teagasc | Agriculture and Food Development Authority

A new study shows that solar photovoltaic systems can reduce emissions and energy costs on dairy farms, with spring-calving systems showing slightly stronger economic and environmental performance.
Integrating renewable energy into agricultural systems is important for reducing the sector’s greenhouse gas emissions. Ireland is targeting a 22-30% reduction in agricultural emissions, a 62-81% reduction in the electricity sector, and an 80% renewable electricity share by 2030 (relative to 2018 levels).
A recent study conducted at Maynooth University and Teagasc, funded by the Sustainable Energy Authority of Ireland, carried out a comprehensive techno-economic and environmental assessment of grid-connected solar photovoltaic (PV) systems for two types of dairy farm operations: spring-calving and winter-calving.
Anne Kinsella, a Senior Research Officer in Teagasc’s Rural Economy and Development programme, says that results are promising.
“The findings demonstrate that solar PV systems are both economically viable and environmentally beneficial for dairy farms. Spring-calving operations tend towards achieving slightly better results, owing to better seasonal alignment between solar generation and electricity demand.”
Taking Ireland’s policy framework into consideration, this study sought to model and optimise solar PV systems to meet farm energy needs. The basis for the modelling was two real-life case farms, from which the study gained detailed energy consumption profiles and data on solar irradiance – the power per unit area received from the sun (measured as watts per m2).
Ireland’s policy framework includes the Targeted Agricultural Modernisation Scheme (TAMS), which offers up to 60% capital grant aid for solar PV systems (maximum investment ceiling of €90,000 per farm), and the Clean Export Tariff, which allows small-scale generators (6-50kWp) to receive €0.15–€0.25/kWh for surplus electricity exported to the grid (contracts of up to 15 years).
Two representative dairy farm operations were evaluated in County Galway, western Ireland: a spring-calving farm at Ballymoe and a winter-calving farm at Athenry. The spring-calving operation uses an automated milking and grazing-management system for 80 cows under a largely pasture-based regime, which raises electricity demand during peak milking periods. The winter-calving operation, with 74 cows, uses robotic milking and continuous indoor housing during colder months, increasing electricity demand.
Monthly electricity consumption profiles based on actual farm electricity bills were analysed. Major energy-consuming operations common to both farms include milking machines, milk cooling, water heating, water pumps, manure scrapers and lighting. Monthly solar irradiance data were also obtained for both locations, with the Athenry site receiving slightly higher annual solar irradiance than Ballymoe.
The proposed PV system consists of three main components: a solar PV array, a battery bank and an inverter. The battery system mitigates the intermittent nature of solar generation, while the inverter converts direct current (DC) from both the solar PV array and the battery into alternating current (AC) suitable for farm operations.
As the dairy farms are connected to existing low-voltage grid infrastructure, there is no requirement for additional high-voltage conversion equipment. This simplifies system integration and reduces installation costs.
The analysis involved collecting all required input data, including solar irradiance, farm-specific energy consumption profiles, component efficiencies, capital and operating costs and relevant policy schemes. The operating strategy prioritises on-site solar PV utilisation to meet farm electricity demand, with any surplus charging the battery until it is full. Additional excess electricity is exported to the grid at the applicable tariff.
During periods of insufficient solar PV generation, the battery discharges to support the load, and the grid supplies electricity only when both solar PV and battery outputs cannot meet demand.
The solar PV model for the spring-calving operation (utilising 30.4kWp) consisted of 76 solar PV panels and 20 battery units. The model developed for the winter-calving dairy operation (utilising 27.6 kWp) consisted of 69 panels and 25 battery units.
“In terms of energy generation, total annual solar PV generation was comparable for both dairy operations,” explains Anne. “The spring-calving operation generated 29,882kWh while the winter-calving operation generated 29,687kWh. However, their utilisation patterns differ significantly.”
On the spring-calving farm, 72% of solar PV energy (21,635kWh) was consumed directly on site, 23% (6,685kWh) was stored in batteries, and only 5% (1,562kWh) was exported to the grid. This means that 95% of solar PV energy was effectively used on the farm, reflecting strong on-site utilisation and reduced grid dependence.
In contrast, the winter-calving farm consumed 51% (15,040kWh) of solar PV energy directly, stored 25% (7,512 kWh) in batteries, and exported 24% (7,134kWh) to the grid. “During low-irradiance months, i.e. winter, peak electricity demand limits self-use and increases exports,” Anne notes.
For the spring-calving operation, solar PV, battery storage and grid imports contributed 59%, 18% and 23% of total energy, respectively, compared to 41%, 20% and 39% for the winter-calving operation. The winter-calving farm also contributed a higher grid export of 19%. These findings highlight the lower utilisation of on-site solar PV energy due to seasonal mismatch in winter-calving systems.
To evaluate the performance of the proposed system, three indicators were assessed:
“Economic results show that both types of dairy operations benefit from solar energy integration,” explains Michael Hayden of Maynooth University, “although the spring-calving operation performs more favourably due to the stronger alignment between solar generation and electricity demand.”
Under current Irish policy conditions, the spring-calving operation achieved a payback period of 3.25 years and an LCOE of €0.091/kWh, compared with 3.83 years and €0.099/kWh for the winter-calving operation.
Sensitivity analysis identified solar irradiance, grant funding and grid electricity prices as the most influential factors affecting financial performance.
Environmentally, the proposed systems achieved significant emissions reductions of 77% for the spring calving operation and 61% for the winter-calving operation.
Overall, the findings confirm that solar PV systems offer a practical and sustainable pathway for improving energy self-sufficiency, profitability and environmental performance in dairy farming.
“These results provide useful insights for farmers and policymakers seeking to promote renewable energy adoption and emissions reduction in agriculture,” Michael concludes.
“Greater adoption of solar PV technologies across the agricultural sector could help develop more economically and environmentally sustainable farm enterprises – creating a win-win scenario for all stakeholders in agriculture.”

New Orleans renter says 30-year-old AC left apartment at 93 degrees after supposed maintenance fix – The Cool Down

The situation reflects a broader issue in rental housing.

For renters facing extreme heat, a broken air conditioner can quickly turn an uncomfortable home into a serious health concern.
That was the case for one New Orleans renter who turned to Reddit for advice after a broken HVAC system left their apartment at 93 degrees Fahrenheit.
The tenant described the issue in a post on the r/HVACAdvice subreddit. According to the post, the apartment’s AC had been down for five days before maintenance checked it.
Management then told the renter to file another maintenance request and said the system would probably have to be replaced. But when the renter got home, they explained their apartment was 93 degrees despite the thermostat being set 13 degrees lower. 
The renter took to Reddit, asking users how long a potential replacement would take to install. 
Reddit users said there is no standard wait time for that kind of replacement. As one commenter put it, “No one here is going to be able to answer this question,” since the timeline depends on the installer, that company’s backlog, and whether the needed equipment is available. The same commenter said that once technicians arrive ready to work, the installation itself “will just take hours.”

Others said the bigger delay may come from apartment approval processes, scheduling, and whether management is willing to provide a temporary cooling option while the central unit is down.
In this case, commenters noted that a 30-year-old air conditioner would likely be far less efficient than a modern replacement, affecting comfort and utility costs, especially in a hot, humid place such as New Orleans, where cooling systems may run hard for long stretches.
This situation also reflects a broader issue in rental housing. When renters are blocked from making simple home changes and also have to wait on management to address failing major systems, their options for cutting costs or staying comfortable can shrink fast.
For many households, that can mean higher power bills, worse indoor air quality, and more stress during heat waves.
Documentation can help support requests for faster action: records of indoor temperatures, maintenance notes, and every submitted work order, especially where local housing rules set minimum cooling standards.
Several commenters recommended requesting a window or portable unit in writing if a full replacement is delayed. “Ask for a window AC,” said one user. “They should have a few of those (or maybe a portable AC).”

Solar Motorcycles in 2026: What Works, What’s a Concept, and the Math Behind Self-Charging – Intelligent Living

Date:
In November 2025, a Turkish-Italian architecture studio called MASK Architects unveiled a striking two-wheeler: the Solaris, a motorcycle whose retractable circular solar “wings” unfurl like a mechanical flower whenever the bike is parked. Within days, headlines declared it the world’s first self-charging solar motorcycle, a machine that, in the founders’ words, would free riders “from fuel, grids, plugs, and the economics of energy itself.”
It was a beautiful pitch. It was also a concept.
If you searched for a “solar motorcycle” today, you’d land on a strange mix: a flashy concept bike that won’t reach production for years, a handful of real production motorcycles and scooters that actually do carry solar panels but rarely top 40 mph, and a 70 mph electric motorcycle called the Solar E-Clipse whose name contains the word “solar” but whose battery is plugged into a wall outlet, not the sun. Confusion reigns, and the math behind why truly self-charging solar motorcycles remain rare tells you more about the limits of photovoltaic surface area than any concept render ever could.
This guide breaks down what a solar motorcycle actually is, what you can realistically buy in 2026, and why the dream of unlimited solar range on two wheels still runs into stubborn physics.
Table of Contents
The Solaris first surfaced in late November 2025 via a coordinated reveal across design media. The bike is the work of MASK Architects (sometimes styled MARS Architects), an international design studio led by Öznur Pınar Cer and Danilo Petta, whose “Invent and Integrate” approach treats speculative design as a way to seed real engineering projects.
Three features define the Solaris:
The visual language is equally deliberate: a stretched front end, a muscular forward-leaning stance, and flowing bodywork inspired by the anatomy of a leaping leopard. MASK Architects describes the Solaris as a “self-sustaining organism” rather than a vehicle.
What MASK has not disclosed is just as telling. There are no published figures for top speed, 0-60 mph time, battery capacity in kWh, motor output in kW, range per charge, range per day of solar charging, weight in kilograms, or projected price. The company describes performance only as “high-torque electric motor.” As of this writing, the Solaris remains a one-off concept, with no announced production partner, manufacturing timeline, or pre-order pathway. Whether the design ever reaches a dealership floor depends on whether MASK finds an OEM willing to industrialize a fundamentally unusual vehicle architecture.
The Solaris concept leans on a powerful narrative: a vehicle that harvests enough energy from the sun to extend its range indefinitely. The math is more sobering than the marketing suggests.
A typical motorcycle silhouette offers, generously, two square meters of usable surface area once you account for bodywork, fairings, and a top surface that sees direct sun. A modern production photovoltaic panel converts around 22% of incident sunlight into electricity under ideal lab conditions, closer to 18-20% in real-world riding. Average peak solar irradiance in sun-belt regions is roughly 1,000 watts per square meter at noon, dropping to an effective daily average closer to 200-250 W/m2 when you integrate morning, midday, afternoon, and weather variation.
That gives you a realistic solar harvest of roughly 0.36 to 0.5 kWh per square meter per day in good conditions, or about 0.7 to 1 kWh per day for a two-square-meter motorcycle, before efficiency losses. A typical electric motorcycle consumes between 0.1 and 0.2 kWh per mile depending on speed and weight. The numbers line up to perhaps 5-10 miles of solar range per day in genuinely sunny climates, before you even factor in shade from the rider, parked angle, dust on the panels, or the energy the bike uses to power its own management systems.
The Aptera three-wheeled solar EV, a vehicle purpose-built around maximizing solar surface area, confirms this ceiling in real engineering. Aptera’s published specifications, available on the official Aptera site, claim 700 watts of integrated solar capacity delivering up to 40 miles of free solar range per day in sunny California summers.
Independent analysis published by Green Car Reports pegs the more conservative real-world figure at 20-30 miles per day in summer, falling to around 10 miles per day in average conditions. That is from a vehicle whose every aerodynamic curve is a solar panel.
For a conventional motorcycle silhouette, even an aggressive one like the Solaris with its deployed circular wings, you are looking at the low end of that range. Solar is genuinely useful as a range extender, especially for commuters who park outdoors or riders in remote regions where charging infrastructure is sparse. It is not, in present physics, a replacement for plugging in.
One of the strangest side effects of the solar motorcycle conversation is how often it leads searchers to the wrong product. If you typed “solar motorcycle” into Google, the top result is the Solar E-Clipse, a real, street-legal electric motorcycle built by a UK company called Solar Scooters. The E-Clipse is electric. It is not solar.
The bike’s 72V 45Ah lithium-ion battery charges only from a wall outlet or a separately purchased portable solar generator. There are no photovoltaic cells anywhere on the bodywork, despite the sun-themed styling cues on its fairings. Multiple reviewers, including the German e-mobility publication Steckerbiker, have noted that “Solar” in this context is purely the manufacturer’s brand name, not a technology claim.
The confusion matters because the Solar E-Clipse’s popularity, both as a search result and as a real street-legal product, has crowded out awareness of genuine solar-powered two-wheelers that do exist today. The rest of this article focuses on those.
Outside the concept-render world, a handful of small manufacturers are already selling or pre-selling two-wheelers that harvest sunlight through onboard panels. They are not as sleek as the Solaris and most do not break 40 mph, but they exist, they ship, and they prove the underlying physics works at a small scale.
Chinese manufacturer Jiangsu YongLE New Energy Electric Vehicle Co. has put the CG into production, a utility-style electric motorcycle built on a Honda CG125-style chassis with a 250W solar panel and a small wind turbine mounted on a roof cage above the rider. The CG uses a 1,500W electric motor and a 30Ah lithium-iron-phosphate battery, reaching a top speed of around 37 mph (59 km/h). On a full charge it covers 50-75 miles (80-120 km), and on solar and wind input alone it manages roughly 31 miles (50 km), according to a detailed New Atlas breakdown.
The roof-and-turbine arrangement looks ungainly, more like a small delivery tuk-tuk than a sport bike, but the design is deliberate: it captures energy both while parked in the sun and while moving through the wind. The CG also supports plug-in charging from a standard 110-220V outlet, with a 6-8 hour full-charge time. Disc brakes front and rear, a 3-speed transmission, and a claimed curb weight of 293 lb (133 kg) round out the package. Pricing has not been publicly disclosed by the company, and the bike is currently sold only in China.
San Francisco-based Otherlab has taken a different approach with the Lightfoot, a two-seat electric cargo scooter that integrates two 120W solar panels directly into its clamshell bodywork. There are no folding panels to remember, no external accessories, and no setup routine. You park it in the sun, and it charges.
Otherlab claims the Lightfoot’s panels can add up to 18 miles of range per day in good sunlight, roughly three miles per hour of strong exposure. The base 1.1 kWh battery delivers up to 37 miles of plug-in range, with an 80% recharge achievable in 90 minutes from a standard wall outlet. A 750W brushless hub motor drives each rear wheel, the top speed is just under 20 mph, and the 45.2-liter lockable cargo bay can haul up to 33 lbs. The Lightfoot weighs about 136 lb (62 kg) and retails for $4,995.
Caveats matter here. The Lightfoot was announced in November 2024 with first deliveries promised for January 2025. As of mid-2026 the company is still operating in reservation and pre-order mode, with no verifiable independent owner reviews. Italian e-mobility outlet Futuro Prossimo published a lengthy investigation in August 2026 documenting how the same specs have been recycled in press coverage for nearly two years without a single owner delivery confirmed. The product is real and the technology works in demonstrations, but buyers should treat the timeline as soft until production deliveries begin.
The most recent entrant, and arguably the most ambitious of the production-bound designs, is the Phosgo Go5 Ultra, a US-spec electric bike with four solar panels integrated into the wheel discs themselves. According to the product launch coverage and a detailed review on Notebookcheck, the Go5 Ultra pairs a Bafang M430 750W mid-drive motor with a 720 Wh LG battery and 200W of integrated wheel solar capacity, with back-contact cells rated above 26% efficiency.
Phosgo claims the solar system can add up to 17 miles of range per day, extend total range to roughly 120 miles, and let a typical commuter go up to a month between plug-in charges. The US version tops out at 28 mph; the EU version is software-limited to 25 km/h to comply with EPAC regulations. Pre-orders opened at $2,199 via Indiegogo in July 2026, well below the $5,999 MSRP.
The novelty of putting solar cells in the wheels is that they charge both when parked and while riding, a meaningful upgrade over bodywork panels that only work in direct sunlight at standstill. Whether the wheel-integrated design holds up to potholes, curb strikes, and rain in real-world use is the open question, and one only production deliveries and time will answer.
San Diego-based Spy Motorcycles grabbed headlines in 2022 with claims of a 125-mile-range, 75 mph electric motorcycle with integrated solar panels, billed as “the world’s first.” The brand’s website went dark within two years, no social media updates followed, and the company appears to have dissolved without delivering production units. WebBikeWorld profiled the project in late 2024 as a cautionary case for would-be solar motorcycle buyers: bold claims, prototype photos, and pre-order pages are not the same as delivered vehicles.
The price range for solar-equipped two-wheelers in 2026 spans an order of magnitude, depending on whether the bike has actual solar hardware or just solar in the name.
The honest takeaway: a genuine solar-powered two-wheeler with verifiable delivery in 2026 is real but rare. The YongLE Risheng CG ships in China and is the closest thing to a production solar motorcycle today. The Otherlab Lightfoot and Phosgo Go5 Ultra both have functional prototypes and pre-order pipelines, but neither has documented owner deliveries at scale yet. Aptera sits in a class of its own, with three wheels, autocycle licensing, and a 2026 production target. For riders who want to plug in real solar input today without waiting for deliveries, the established route remains portable: any plug-in electric motorcycle can pair with a folding solar panel and a portable power station from brands like Jackery, Bluetti, or EcoFlow for off-grid charging.
For most riders considering a “solar motorcycle” in 2026, the practical decision sits between a true solar machine with modest performance, a three-wheeled solar EV, and a plug-in electric bike they can buy today.
The trade-offs are stark. The YongLE CG gives real solar input and full motorcycle-class performance, but its 37 mph top speed and 31-mile solar range make it a commuter, not a highway bike. The Otherlab Lightfoot is the most practical urban runabout but tops out under 20 mph and is technically a scooter, not a motorcycle. Aptera offers real solar autonomy with car-class performance, but it is heavy, three-wheeled, and only available as a 2026 reservation. The Solar E-Clipse delivers genuine motorcycle speed and price-to-performance, but it is not solar-powered at all. There is no single winner because the four vehicles serve fundamentally different use cases; the right choice depends on whether the rider needs solar range, highway speed, or both.
It depends on what you are riding and where. The YongLE Risheng CG is classified as an electric moped or low-speed electric motorcycle in China and is legal on roads and bike lanes under local moped regulations. In most US states, a sub-40 mph electric motorcycle typically requires a motorcycle license or endorsement, registration, and standard equipment (lights, mirrors, horn, and turn signals).
The Otherlab Lightfoot is designed to comply with US Class 2 e-bike regulations in most states, has a top speed under 20 mph, and can typically be ridden in bike lanes without a motorcycle license. Riders should still check their state’s specific e-bike classification rules, which vary for throttle-equipped versus pedal-assist models.
The Phosgo Go5 Ultra US version, at 28 mph and 750W, sits at the upper edge of federal Class 2 e-bike limits. Several US states impose stricter rules, and Phosgo has not published state-by-state compliance documentation. Buyers should verify legality in their jurisdiction before placing a pre-order.
Aptera occupies a different legal niche. Most US states classify three-wheeled vehicles with specific weight and speed thresholds as autocycles rather than motorcycles, which means riders do not need a motorcycle endorsement to drive one. Intelligent Living previously covered Aptera’s never-needs-charging solar EV in detail when production plans first emerged. A few states still require a motorcycle license for any three-wheeler. If you are considering an Aptera reservation, check your state’s autocycle laws before placing the deposit.
Yes, but with caveats. The YongLE Risheng CG is the only production two-wheeled motorcycle currently shipping with onboard solar hardware (250W roof panel plus a wind turbine), and it is sold only in China. The Otherlab Lightfoot and Phosgo Go5 Ultra both integrate solar panels into their bodywork and wheels, but neither has documented owner deliveries at scale. The MASK Architects Solaris is the most ambitious solar motorcycle concept, with retractable circular photovoltaic wings, but it remains a design study with no production partner.
Genuine solar-powered two-wheelers range from $2,199 for a pre-order Phosgo Go5 Ultra e-bike to $4,995 for an Otherlab Lightfoot cargo scooter to “unannounced” for the YongLE Risheng CG. The Aptera three-wheeled solar EV starts at $33,200 for a Launch Edition reservation, with production targeted for late 2026. The Solar E-Clipse 2.0, often the top search result for “solar motorcycle,” is the cheapest at $5,995, but it is not actually solar-powered; “Solar” is the manufacturer’s brand name.
The Solar E-Clipse is fully street-legal in most US states and EU countries when registered as an electric motorcycle, but it is not solar-powered. The brand is called Solar Scooters UK, and “Solar” is a name, not a technology. The astronomical event (a solar eclipse) and the motorcycle brand are unrelated. If you actually want a motorcycle that charges from the sun, the YongLE Risheng CG is the closest production option, sold in China with a 250W onboard solar panel.
Among motorcycles that come up when searching “solar,” the Solar E-Clipse 2.0 Race Edition is one of the most affordable at 70 mph ($6,799, 16 kW peak motor), though it is not actually solar-powered. Among genuine production electric motorcycles, the Zero SR/F (~120 mph, ~20,000), Energica Experia (~112 mph, ~29,000), and Can-Am Pulse (87 mph, ~8,999) all clear 70 mph. For genuine solar-equipped bikes, no current production model exceeds 40 mph.
Technically yes, practically limited. The YongLE Risheng CG can run on solar and wind input alone for roughly 31 miles per day in good conditions, but only at low speed and only with the roof-mounted turbine and panel both contributing. The MASK Architects Solaris concept is designed around full solar autonomy but has no disclosed daily range and is not yet a production vehicle. The physics of photovoltaic surface area on a two-wheeler’s silhouette caps real-world solar input at roughly 5-10 miles of range per day in good conditions for a typical motorcycle, with smaller vehicles like the Phosgo Go5 Ultra e-bike claiming up to 17 miles per day from wheel-integrated panels.
Solar panels themselves degrade slowly, typically 0.5-1% efficiency loss per year, meaning a quality panel still produces 80-90% of its original output after 20-25 years. The electric motorcycle components (battery, motor, and controller) follow standard EV longevity: batteries last 8-15 years depending on chemistry and care, while motors and controllers can run for decades with minimal maintenance. The YongLE Risheng CG’s lithium-iron-phosphate battery chemistry is particularly long-lived, often rated for 2,000+ charge cycles. The Phosgo Go5 Ultra uses LG 21700 cells with similar durability expectations.
The solar motorcycle market in 2026 is a story of three very different futures coexisting at once. MASK Architects’ Solaris shows what a fully self-charging two-wheeler could look like once battery and panel technology catch up with the designers’ ambitions. The YongLE Risheng CG, Otherlab Lightfoot, and Phosgo Go5 Ultra show what is actually shipping, or about to ship, today: real solar input, modest performance, and pricing that ranges from accessible to aspirational. Aptera shows what an extra wheel and a much larger surface area can do when the entire vehicle shape is rebuilt around solar capture. All three point in the same direction: a near future where sunlight is a meaningful contributor to how we move on two wheels, even if it is not yet the only contributor.

For homeowners who either cannot use their roof for solar or simply prefer not to, a different setup is coming onto the market.
Artisanal PV, a Delaware-based solar firm, is shaking up the home-solar industry with an outdoor carport that hosts a solar panel array.
As Solar Builder Magazine reported, the company’s flagship model is a freestanding carport designed to generate solar power for a home without relying on a roof installation.
The structure is about 18 feet long and 15 feet wide, the company said, with room for one large SUV or two smaller sedans.
At full build-out, the modular unit can accommodate up to 12 standard residential solar panels and is rated for 4.8-5.2 kilowatts of output. In addition to shading a parked vehicle, it could help a home generate part of its own electricity and potentially power EV charging.
Ken Fields, founder of Artisanal PV, told the outlet that appearance was a key consideration.

“It’s a beautiful and thoughtfully designed structure that is unique compared to other offerings on the market,” Fields told Solar Builder Magazine.
The company said it wants the carport to work in residential environments rather than resemble a bulky commercial installation, and it offers customizable exterior inlays including wood molding, tiles, and brick veneers.
A rooftop system is not practical for every home, and that limitation is part of what this product is meant to address.
Solar production can be limited by excessive shading, an unfavorable roof angle, or an unfavorable roof orientation. Some homeowners also run into added complications from homeowners associations or historic preservation requirements.
For those households, a solar carport could provide another path to using cleaner energy.
Generating electricity at home can reduce dependence on utility-supplied power, potentially lowering monthly bills over time. When combined with EV charging, it could also reduce fuel costs and gasoline-related air pollution.
Artisanal PV also said the structure is built to handle severe weather, including hurricanes and heavy snow.
The company is testing demand while working toward commercialization. It is accepting fully refundable advance-reservation preorders for $150.
Artisanal PV expects production to begin in Q4 2026, and the first deliveries are planned for late spring 2027.
If interest builds, the design could give more households a way to go solar without major roof work or the aesthetic tradeoffs some homeowners want to avoid.
Wider adoption of options like this could also help cities and utilities expand distributed energy generation across more neighborhoods, potentially reducing grid strain while giving residents another opportunity to save money at home.
“We’re pretty excited about this idea,” Fields told Solar Builder Magazine. “According to the National Renewable Energy Laboratory for any number of reasons it’s estimated that up to 49% of our housing stock can’t currently install solar panels.”

UK homeowner weighs aesthetics and energy production with solar panel installation – The Cool Down

“Pretty sure the vast majority of us get envy from seeing houses with more panels.”

For a homeowner in the United Kingdom, a renewable energy question was shaped as much by curb appeal as by electricity production. The sticking point was whether fitting five extra solar panels would make the roof look too crowded.
That trade-off between appearance and capacity had a real cost: choosing the smaller setup meant about three additional years before the system would pay for itself.
On Reddit, a homeowner said their roof could hold 15 panels, though a 10-panel arrangement would “be easy and more in keeping with the village.” The two options were quoted at less than £1,000 (around $1,300) apart, but choosing the smaller system would extend the expected return on investment from roughly 7 years to 10 years.
One commenter argued for using all the available space, writing, “If 15 fits then do that. Pretty sure the vast majority of us get envy from seeing houses with more panels.”

For households working through a similar calculation, going solar is one of the best ways to cut home energy costs. It may be worth exploring EnergySage to get free solar installation estimates and compare quotes before deciding on the most sensible system size.
The post reflected more than a basic debate over whether solar was “worth it.” The homeowner was balancing looks, future plans, and the possibility of later wishing they had gone bigger. They also worried that export payments from energy providers might no longer be available by the time the extra power generation really mattered.
Solar purchases are made based on current costs and policies, but the systems are designed to operate for decades. When homeowners are uncertain about future utility rates or how much they will be paid for sending electricity back to the grid, maximizing self-use and choosing the right system size from the beginning can feel even more critical.
The shape and orientation of a roof can make that choice even harder.

Engineering Anionic Sublattices in Perovskite Heterostructures Advances Tandem Solar Cells – Bioengineer.org

Solar technology has spent years chasing a difficult combination: higher efficiency without sacrificing durability. A new perovskite design could bring that challenge closer to resolution by changing not only the composition of a light-absorbing film, but also the behavior of the negatively charged ions inside its crystal lattice. In a study reported in Nature Synthesis, researchers engineered dynamically disordered cyanate anions into wide-bandgap perovskite materials and used them to build a more efficient, more stable top cell for perovskite–silicon tandem photovoltaics. The resulting tandem device achieved a power conversion efficiency of 34.79%, with an independently certified efficiency of 34.29%. It also retained 95% of its initial performance after 1,100 hours of continuous illumination, while extended outdoor-style testing continued for more than 1,300 hours. The work points to a chemical strategy for addressing one of the most persistent weaknesses in next-generation solar cells: the tendency for the materials that deliver high voltage to be especially vulnerable to energy loss and degradation.
Perovskites are a family of semiconductors whose crystal structures can be tuned by mixing different ions. Their strong absorption, adjustable bandgaps and ability to form thin films have made them leading candidates for tandem solar cells, in which two light-absorbing devices are stacked so they can harvest different portions of sunlight. Silicon is particularly effective at converting lower-energy visible and near-infrared light, while a wide-bandgap perovskite top cell can absorb higher-energy photons before they reach the silicon layer. In principle, this division of labor allows a tandem device to produce more electricity than either material could generate alone. In practice, wide-bandgap perovskite top cells often suffer from a voltage deficit: the voltage delivered by the operating solar cell falls significantly below the energy expected from the material’s optical bandgap. Non-radiative recombination, in which excited electrons and holes lose their energy as heat rather than light or electrical current, is a major cause.
The new approach focuses on the anionic sublattice, the network of negatively charged ions that helps define the perovskite crystal’s structure and electronic environment. Rather than treating these anions as passive components, the researchers designed perovskite derivatives containing cyanate anions with dynamic disorder. This means that the anions are not locked into a single perfectly static arrangement within the lattice. Their changing local configurations can influence how the material crystallizes and how charges move through it. The researchers used this behavior to alter crystallization kinetics—the rates and pathways by which a thin film transforms from a precursor mixture into an ordered semiconductor. According to the study, this dynamic anionic engineering directed the formation of a coherent bulk heterojunction, a continuous internal architecture in which related semiconductor regions are intimately connected rather than separated into poorly matched domains.
That structural control matters because the microscopic quality of a perovskite film determines how efficiently it handles photogenerated charge. During crystallization, imperfections can form at grain boundaries, where individual crystalline regions meet, and at interfaces between different materials. These sites can contain electronic defects known as trap states. Deep-level traps are especially damaging because they can capture electrons or holes and facilitate non-radiative recombination, shortening the time available for charges to reach the electrical contacts. A solar cell may therefore absorb sunlight efficiently while still losing much of the resulting energy before it becomes usable current. The cyanate-containing materials were designed to act at these vulnerable locations. The study reports that the anions provided chemical and electronic passivation at grain boundaries and interfaces, effectively neutralizing deep-level traps and suppressing the recombination pathways that create voltage losses.
The film morphology produced by the method was also important. The researchers observed large-grained material, meaning the perovskite contained relatively broad crystalline regions with fewer grain boundaries per unit area. Large grains do not automatically guarantee a high-performing solar cell, because defects can still occur within crystals or at contacts, but reducing the total density of boundaries can limit the number of locations where charge carriers become trapped. The reported coherent bulk heterojunction adds another layer of control by creating a connected internal structure that supports charge transport across the absorber. Together, the crystallization pathway, grain growth and interfacial passivation address different parts of the same problem: keeping photogenerated carriers mobile and preventing them from dissipating their energy before extraction.
The performance results show how those chemical and structural changes translated into working devices. A single-junction wide-bandgap perovskite solar cell made using the method reached a power conversion efficiency of 24.35%. Power conversion efficiency is the fraction of incident sunlight converted into electrical power, and in a wide-bandgap perovskite cell it reflects the balance among current generation, voltage, and the fill factor, which describes how effectively the device maintains useful power across its operating range. The more consequential result came when the perovskite was placed above a silicon cell in a monolithic tandem architecture. Because the two subcells are connected within a single integrated device, the top perovskite layer must transmit suitable light to the silicon beneath it while generating a high voltage of its own. The tandem reached 34.79% efficiency in the reported measurements, and a certified value of 34.29% provided an independently validated benchmark.
Tandem photovoltaics are attractive partly because they can surpass the practical efficiency ceiling of conventional single-junction silicon. A single semiconductor absorbs photons over a limited energy range: photons below its bandgap pass through or are weakly absorbed, while excess photon energy above the bandgap is lost as heat. Stacking materials with different bandgaps reduces both forms of loss. Yet this design also increases the number of interfaces and processing constraints. The top perovskite must be deposited without damaging the silicon device, remain optically and electrically compatible with the lower cell, and withstand illumination, heat and electrical stress over time. Wide-bandgap compositions have been particularly challenging because increasing the bandgap can intensify chemical instability and promote non-radiative losses. By engineering the anion chemistry rather than relying solely on broad compositional adjustments, the researchers sought to improve efficiency and stability through the same underlying material design.
Durability testing provided a second major result. Under the ISOS-L-1 protocol, which evaluates operational stability under continuous illumination, the tandem retained 95% of its initial performance after 1,100 hours. The study also reports more than 1,300 hours of extended real-world testing under the ISOS-O-2 protocol. Stability measurements are crucial for perovskite technology because impressive initial efficiencies have often been accompanied by rapid performance declines. Perovskite crystals and their interfaces can respond to light, temperature and electric fields, with ions moving through the lattice or chemical reactions developing at contacts. Such changes can create new defects, alter the distribution of elements and undermine the electrical properties of the device. The reported retention under both continuous illumination and longer-duration real-world conditions suggests that the cyanate-based design may suppress several degradation pathways, although the timescales remain short compared with the operational lifetimes expected of commercial solar modules.
The significance of the work is therefore broader than a single efficiency record. It demonstrates that the negative-ion framework of a perovskite can be deliberately designed to control processes occurring at multiple scales, from the motion and disorder of individual anions to the crystallization of the full absorber and the behavior of interfaces in a tandem device. The researchers describe this strategy as dynamic anionic sublattice engineering, emphasizing that anions can actively shape the formation and operation of the semiconductor. That concept could help materials scientists move beyond a trial-and-error search through combinations of elements. By selecting anions for their effects on crystallization, defect chemistry and electronic passivation, researchers may be able to design perovskites around specific performance requirements. In this case, the approach was aimed at the stability–performance trade-off, the tendency for improvements in efficiency to be offset by faster degradation.
The new results do not by themselves establish that perovskite–silicon tandems are ready for mass deployment. Commercialization will still depend on manufacturing uniform large-area films, protecting devices from moisture and heat, maintaining performance across millions of cells and demonstrating long-term reliability under diverse climates. Certified laboratory efficiency and controlled stability testing are essential milestones, but they are not substitutes for years of field operation. Even so, the study offers a compelling blueprint for tackling the materials problems that stand between laboratory devices and practical solar power. By using dynamically disordered cyanate anions to guide crystallization, passivate defects and support a coherent heterostructure, the researchers produced a tandem cell that combines unusually high efficiency with substantial short-term operational retention. If the chemistry can be translated to scalable manufacturing, engineering the anionic sublattice could become one of the most important tools for turning perovskite–silicon tandems from high-performance experiments into a durable source of low-carbon electricity.

Students walked among 12,000 panels at a Pennsylvania solar farm carrying collecting gear because they were counting spiders between the rows, and nobody had surveyed them there since 1942 – Energies Media

Energies Media
A Pennsylvania solar farm demonstrates how thousands of panels can impact micro-environments.
The world’s rising electricity demands are necessitating the acceleration of the global energy transition.
In turn, this requires vast stretches of land to accommodate the large-scale installations.
Biodiversity loss is a common concern, but these sites also interact with the environment on a small scale.
Will the latest research in Pennsylvania help developers understand the true micro-ecological impact?
Global climate regulations require preventing Earth’s temperature from rising above the threshold compared to 1990 levels.
This particular goal has become more complicated.
The digital age consumes substantial electricity to maintain operations.
In the U.S., AI and data centers are the main culprits.
Data centers consume roughly 200 terawatt-hours of the nation’s total power annually.
AI workloads are responsible for nearly 2% of America’s total electricity demand.
These demands are expected to grow continuously, placing unprecedented strain on regional power grids.
When electricity usage is too high, operators must execute emergency steps to balance the grid.
This can range from public alerts to mandatory power cuts.
Often, potential blackouts and cascading failures are prevented by switching on fossil fuel plants as backup.
But this is not the answer to keeping the nation’s lights on sustainably.
The rapid deployment of utility-scale renewable infrastructure is needed to close the energy gap without increasing emissions.
In the United States, between 50% and 66% of all new power generating capacity additions are attributed to solar energy.
It has been the number one newly installed capacity for a while.
However, more utility-scale projects are required to anchor America’s clean energy transition.
Thanks to solar’s high scalability and cost-effectiveness, this should not take too long.
Yet, the deployment of these crucial projects has been frequently delayed.
Extreme competition over land use and opposition from local communities are primary reasons.
Installing thousands of panels requires vast tracts of flat, unshaded land.
Standard projects often span hundreds of thousands of acres.
Those contesting these facilities argue that altering open land will threaten regional biodiversity and natural habitats.
Recently, agriculture and solar power began to reconcile.
However, environmentalists are still concerned about micro impacts.
Researchers from Susquehanna University decided to inspect this by conducting a study at a Pennsylvania solar farm.
Solar facilities can affect the surrounding microenvironment.
In Pennsylvania, a landmark field study was conducted at the university’s operating photovoltaic plant to understand these effects.
The facility consists of 12,000 panels, generating approximately 30% of the campus power.
This fenced-off industrial zone was viewed as an undisturbed microhabitat.
Student researchers, armed with collecting gear, walked between the rows to survey and count spiders.
The ground beneath the panels never experiences heavy tilling, intense foot traffic, or chemical spraying.
As a result, the solar site evolved into a protected safe space for the spiders.
The low disturbance and shade are ideal conditions for diverse arthropod communities to prosper.
The field study’s findings challenge the belief that clean energy installations become biological dead zones.
The research demonstrates how renewable power facilities can support conservation in the most unexpected ways.
The findings will prove to be highly beneficial as America’s solar capacity rapidly scales toward 2030.
Developers can now plan future utility-scale projects to serve dual purposes, benefiting the grid and nature.
The key is to gain an in-depth understanding of the environment and its local species before construction begins.
This way, thoughtful site layouts can be designed, ensuring America’s clean energy shift peacefully occurs in line with nature conservation.

Bulging, rusted water heater sparks urgent calls to shut it down – The Cool Down

“I’d say it was about to pop like a very expensive balloon.”
Photo Credit: Reddit
One troubled homeowner shared pictures of his water heater that looks like it’s about to pop at any moment with the ominous title: “How dangerous was this hot water heater?”
Online commenters were alarmed by the photos shared. It appeared badly warped and rusted out.
For households already facing a replacement, that kind of situation can also open the door to lower future utility costs. Upgrading from an older electric-resistance model to a heat pump water heater can often reduce energy bills.
After turning off both the gas and water supply, the homeowner asked for advice in a post on Reddit, writing, “already shut off the gas and the water supply. How dangerous was this?” The attached images showed a severely deformed water heater that commenters said looked dangerously close to failing.
One commenter summed up the reaction bluntly: “Whoa. I’d say it was about to pop like a very expensive balloon.”
Another commenter raised a key safety concern: “Is there a pressure relief valve? Wondering if it’s capped.” Water heaters are built to hold hot, pressurized water, and relief valves are one of the main protections against dangerous pressure buildup.
A visibly bulging tank is not just a cosmetic problem. It can point to a serious internal failure that may lead to leaks, flooding, or worse.
Water heaters are usually tucked away out of sight, making it easy for problems to go unnoticed until they become severe. But warping, bulging, leaks near the base, rust around fittings, or unusual noises can all signal that a unit needs immediate attention.
FROM OUR PARTNER
Want to go solar but not sure who to trust? EnergySage has your back with free and transparent quotes from fully vetted providers in your area.
To get started, just answer a few questions about your home — no phone number required. Within a day or two, EnergySage will email you the best options for your needs, and their expert advisers can help you compare quotes and pick a winner.
Solar panels can save you more than $50k over their 25-year lifespan, and EnergySage can help you save as much as $10k on installation. Which begs the question — isn’t that worth an email or two?
People in the thread also pointed to shutdown steps that depend on the type of unit: Electric heaters can be turned off at the breaker, while gas models should have the gas supply shut off. Because the original poster had already cut off the gas and water, those steps likely reduced the immediate danger.
A failing water heater can quickly become both a safety threat and a financial burden. Beyond the risk of a ruptured tank, even a unit that is still limping along can waste energy, raise monthly bills, and leave a household scrambling for an emergency replacement.
If a water heater looks swollen, warped, or otherwise misshapen, the safest move is to stop using it and contact a licensed plumber immediately. A professional can determine whether the issue is pressure-related, structural, or tied to a failed safety component.
For homeowners weighing replacement options, Cala makes smart heat pump water heaters that focus on both efficiency and control. Its customizable smart heat pump water heaters help homeowners decrease their energy bills by heating water exactly when it’s needed. Because they are designed around household demand rather than constantly maintaining excess hot water, they can reduce waste and make utility costs more predictable. 
Homeowners comparing long-term operating costs may want to look at how Cala pairs heat pump efficiency with a more tailored approach to hot water use.
One commenter put the situation into perspective: “Could very well turn into a perfect reenactment of the mythbusters water heater rocket episode.”

North Carolina homeowner weighs outage options as standby generators dwarf portable setups – The Cool Down

While generators are one option, solar panels paired with batteries are another.

For homeowners considering backup power, the price gap between an automatic standby generator and a portable setup may be far wider than many expect.
The question came from a North Carolina resident with a 1,500-square-foot home who wanted a rough idea of how much more a whole-home standby system might cost than a portable generator set up with the proper connections.
In a Reddit thread, the homeowner said they didn’t want to manage individual circuits during an outage. The post said the house is connected to natural gas, has an accessible crawlspace, a 2.5-ton air conditioner and a gas furnace. “I’m not really interested in finagling breakers/appliances/devices to try and get by with a 4kw generator or anything,” the poster wrote.
“Obviously I’ll need to get some quotes, but I was wondering what you all thought would be a rough estimate for the cost difference between a standby solution and a portable solution,” the homeowner added.
Luckily, commenters shared their thoughts, giving the homeowner a clearer picture of what the upgrade will cost. 
One commenter offered a straightforward rule of thumb: “Standby will be 3-4 times the cost of a portable.”

The same commenter said that a properly sized portable system for whole-home use can still require substantial upgrades. “I just updated the inlet and generator breaker and purchased a larger generator with the intent of running the whole house and AC. The whole project cost $5000.”
A portable setup capable of powering an entire home and central air is not necessarily inexpensive, and a permanently installed standby system may cost far more.
The difference between the two options goes beyond convenience. Standby generators are permanently installed, usually connected to a fuel source such as natural gas, and designed to turn on automatically when grid power goes out. Portable generators, by contrast, require manual setup, though they can cost significantly less upfront.
Safety is another major consideration. As the commenter noted, “For the portable you will need a breaker interlock so that your main breaker is off when the generator is powering the house. That prevents your generator from delivering power outside your house.”
Although backup power can be a pricey upgrade, more and more homeowners are investing in backup solutions in the face of increasing power outages. 
While generators are one option, solar panels paired with batteries are another. When paired together, the tech not only provides backup power during emergencies, but also long-term savings on energy costs. 
When exploring options, it’s best to contact professionals to ensure you’re getting the best deal for your home and budget. 
A formal load calculation can show whether a home actually needs a large whole-house generator, would pair well with backup batteries, or whether a smaller system with more targeted coverage would meet most needs.

Homeowner says neighbor's in-roof solar tiles send glare sweeping across doors, kitchen, and office – The Cool Down

Solar tiles are often marketed as a sleeker alternative to traditional rack-mounted panels.

A neighbor’s new solar installation has become an aggravation for one homeowner, who says strong reflections from the system are spilling into several of their rooms.
The family says the roof-integrated setup looks good from the outside, but the light bouncing off it reaches their doors, kitchen window, and home office at certain times of day.
In a post on Reddit, the homeowner said the house next door added in-roof solar tiles. They said the installation takes up about half of the roof area facing their property and that it “looks amazing but unfortunately causes extreme glare into our property when the sun hits it at certain parts of the day.”
According to the post, the glare shifts position throughout the day rather than hitting a single area. The homeowner said it passes over “2 double glass sliding doors and a long kitchen window,” and that one of the rooms affected is the family’s office.
They said the only remedy they had found was window film, but that it was “apparently quite expensive.” Because of that, they asked whether there were any alternatives that could be addressed from the panel side.

Although solar products are designed to absorb sunlight, factors such as roof angle, window placement, and time of day can still make reflected light a nuisance in certain home layouts.
Documenting exactly when and where the glare appears can help when speaking with a neighbor, installer, or local official about the problem.
It can also help to ask the solar installer for product specifications and any manufacturer guidance related to reflectivity. In some cases, the installer may be able to clarify whether approved adjustments or replacement components are available for the affected section.
If the only realistic fix is on the impacted home, getting multiple quotes for window film, shades, or exterior screening may still be worthwhile. While film can come with a high upfront price, it can also reduce heat gain and glare, potentially lowering cooling costs over time and improving comfort in sun-exposed rooms.

Solar Motorcycles in 2026: What Works vs. What's a Concept – Intelligent Living

Date:
In November 2025, a Turkish-Italian architecture studio called MASK Architects unveiled a striking two-wheeler: the Solaris, a motorcycle whose retractable circular solar “wings” unfurl like a mechanical flower whenever the bike is parked. Within days, headlines declared it the world’s first self-charging solar motorcycle, a machine that, in the founders’ words, would free riders “from fuel, grids, plugs, and the economics of energy itself.”
It was a beautiful pitch. It was also a concept.
If you searched for a “solar motorcycle” today, you’d land on a strange mix: a flashy concept bike that won’t reach production for years, a handful of real production motorcycles and scooters that actually do carry solar panels but rarely top 40 mph, and a 70 mph electric motorcycle called the Solar E-Clipse whose name contains the word “solar” but whose battery is plugged into a wall outlet, not the sun. Confusion reigns, and the math behind why truly self-charging solar motorcycles remain rare tells you more about the limits of photovoltaic surface area than any concept render ever could.
This guide breaks down what a solar motorcycle actually is, what you can realistically buy in 2026, and why the dream of unlimited solar range on two wheels still runs into stubborn physics.
Table of Contents
The Solaris first surfaced in late November 2025 via a coordinated reveal across design media. The bike is the work of MASK Architects (sometimes styled MARS Architects), an international design studio led by Öznur Pınar Cer and Danilo Petta, whose “Invent and Integrate” approach treats speculative design as a way to seed real engineering projects.
Three features define the Solaris:
The visual language is equally deliberate: a stretched front end, a muscular forward-leaning stance, and flowing bodywork inspired by the anatomy of a leaping leopard. MASK Architects describes the Solaris as a “self-sustaining organism” rather than a vehicle.
What MASK has not disclosed is just as telling. There are no published figures for top speed, 0-60 mph time, battery capacity in kWh, motor output in kW, range per charge, range per day of solar charging, weight in kilograms, or projected price. The company describes performance only as “high-torque electric motor.” As of this writing, the Solaris remains a one-off concept, with no announced production partner, manufacturing timeline, or pre-order pathway. Whether the design ever reaches a dealership floor depends on whether MASK finds an OEM willing to industrialize a fundamentally unusual vehicle architecture.
The Solaris concept leans on a powerful narrative: a vehicle that harvests enough energy from the sun to extend its range indefinitely. The math is more sobering than the marketing suggests.
A typical motorcycle silhouette offers, generously, two square meters of usable surface area once you account for bodywork, fairings, and a top surface that sees direct sun. A modern production photovoltaic panel converts around 22% of incident sunlight into electricity under ideal lab conditions, closer to 18-20% in real-world riding. Average peak solar irradiance in sun-belt regions is roughly 1,000 watts per square meter at noon, dropping to an effective daily average closer to 200-250 W/m2 when you integrate morning, midday, afternoon, and weather variation.
That gives you a realistic solar harvest of roughly 0.36 to 0.5 kWh per square meter per day in good conditions, or about 0.7 to 1 kWh per day for a two-square-meter motorcycle, before efficiency losses. A typical electric motorcycle consumes between 0.1 and 0.2 kWh per mile depending on speed and weight. The numbers line up to perhaps 5-10 miles of solar range per day in genuinely sunny climates, before you even factor in shade from the rider, parked angle, dust on the panels, or the energy the bike uses to power its own management systems.
The Aptera three-wheeled solar EV, a vehicle purpose-built around maximizing solar surface area, confirms this ceiling in real engineering. Aptera’s published specifications, available on the official Aptera site, claim 700 watts of integrated solar capacity delivering up to 40 miles of free solar range per day in sunny California summers.
Independent analysis published by Green Car Reports pegs the more conservative real-world figure at 20-30 miles per day in summer, falling to around 10 miles per day in average conditions. That is from a vehicle whose every aerodynamic curve is a solar panel.
For a conventional motorcycle silhouette, even an aggressive one like the Solaris with its deployed circular wings, you are looking at the low end of that range. Solar is genuinely useful as a range extender, especially for commuters who park outdoors or riders in remote regions where charging infrastructure is sparse. It is not, in present physics, a replacement for plugging in.
One of the strangest side effects of the solar motorcycle conversation is how often it leads searchers to the wrong product. If you typed “solar motorcycle” into Google, the top result is the Solar E-Clipse, a real, street-legal electric motorcycle built by a UK company called Solar Scooters. The E-Clipse is electric. It is not solar.
The bike’s 72V 45Ah lithium-ion battery charges only from a wall outlet or a separately purchased portable solar generator. There are no photovoltaic cells anywhere on the bodywork, despite the sun-themed styling cues on its fairings. Multiple reviewers, including the German e-mobility publication Steckerbiker, have noted that “Solar” in this context is purely the manufacturer’s brand name, not a technology claim.
The confusion matters because the Solar E-Clipse’s popularity, both as a search result and as a real street-legal product, has crowded out awareness of genuine solar-powered two-wheelers that do exist today. The rest of this article focuses on those.
Outside the concept-render world, a handful of small manufacturers are already selling or pre-selling two-wheelers that harvest sunlight through onboard panels. They are not as sleek as the Solaris and most do not break 40 mph, but they exist, they ship, and they prove the underlying physics works at a small scale.
Chinese manufacturer Jiangsu YongLE New Energy Electric Vehicle Co. has put the CG into production, a utility-style electric motorcycle built on a Honda CG125-style chassis with a 250W solar panel and a small wind turbine mounted on a roof cage above the rider. The CG uses a 1,500W electric motor and a 30Ah lithium-iron-phosphate battery, reaching a top speed of around 37 mph (59 km/h). On a full charge it covers 50-75 miles (80-120 km), and on solar and wind input alone it manages roughly 31 miles (50 km), according to a detailed New Atlas breakdown.
The roof-and-turbine arrangement looks ungainly, more like a small delivery tuk-tuk than a sport bike, but the design is deliberate: it captures energy both while parked in the sun and while moving through the wind. The CG also supports plug-in charging from a standard 110-220V outlet, with a 6-8 hour full-charge time. Disc brakes front and rear, a 3-speed transmission, and a claimed curb weight of 293 lb (133 kg) round out the package. Pricing has not been publicly disclosed by the company, and the bike is currently sold only in China.
San Francisco-based Otherlab has taken a different approach with the Lightfoot, a two-seat electric cargo scooter that integrates two 120W solar panels directly into its clamshell bodywork. There are no folding panels to remember, no external accessories, and no setup routine. You park it in the sun, and it charges.
Otherlab claims the Lightfoot’s panels can add up to 18 miles of range per day in good sunlight, roughly three miles per hour of strong exposure. The base 1.1 kWh battery delivers up to 37 miles of plug-in range, with an 80% recharge achievable in 90 minutes from a standard wall outlet. A 750W brushless hub motor drives each rear wheel, the top speed is just under 20 mph, and the 45.2-liter lockable cargo bay can haul up to 33 lbs. The Lightfoot weighs about 136 lb (62 kg) and retails for $4,995.
Caveats matter here. The Lightfoot was announced in November 2024 with first deliveries promised for January 2025. As of mid-2026 the company is still operating in reservation and pre-order mode, with no verifiable independent owner reviews. Italian e-mobility outlet Futuro Prossimo published a lengthy investigation in August 2026 documenting how the same specs have been recycled in press coverage for nearly two years without a single owner delivery confirmed. The product is real and the technology works in demonstrations, but buyers should treat the timeline as soft until production deliveries begin.
The most recent entrant, and arguably the most ambitious of the production-bound designs, is the Phosgo Go5 Ultra, a US-spec electric bike with four solar panels integrated into the wheel discs themselves. According to the product launch coverage and a detailed review on Notebookcheck, the Go5 Ultra pairs a Bafang M430 750W mid-drive motor with a 720 Wh LG battery and 200W of integrated wheel solar capacity, with back-contact cells rated above 26% efficiency.
Phosgo claims the solar system can add up to 17 miles of range per day, extend total range to roughly 120 miles, and let a typical commuter go up to a month between plug-in charges. The US version tops out at 28 mph; the EU version is software-limited to 25 km/h to comply with EPAC regulations. Pre-orders opened at $2,199 via Indiegogo in July 2026, well below the $5,999 MSRP.
The novelty of putting solar cells in the wheels is that they charge both when parked and while riding, a meaningful upgrade over bodywork panels that only work in direct sunlight at standstill. Whether the wheel-integrated design holds up to potholes, curb strikes, and rain in real-world use is the open question, and one only production deliveries and time will answer.
San Diego-based Spy Motorcycles grabbed headlines in 2022 with claims of a 125-mile-range, 75 mph electric motorcycle with integrated solar panels, billed as “the world’s first.” The brand’s website went dark within two years, no social media updates followed, and the company appears to have dissolved without delivering production units. WebBikeWorld profiled the project in late 2024 as a cautionary case for would-be solar motorcycle buyers: bold claims, prototype photos, and pre-order pages are not the same as delivered vehicles.
The price range for solar-equipped two-wheelers in 2026 spans an order of magnitude, depending on whether the bike has actual solar hardware or just solar in the name.
The honest takeaway: a genuine solar-powered two-wheeler with verifiable delivery in 2026 is real but rare. The YongLE Risheng CG ships in China and is the closest thing to a production solar motorcycle today. The Otherlab Lightfoot and Phosgo Go5 Ultra both have functional prototypes and pre-order pipelines, but neither has documented owner deliveries at scale yet. Aptera sits in a class of its own, with three wheels, autocycle licensing, and a 2026 production target. For riders who want to plug in real solar input today without waiting for deliveries, the established route remains portable: any plug-in electric motorcycle can pair with a folding solar panel and a portable power station from brands like Jackery, Bluetti, or EcoFlow for off-grid charging.
For most riders considering a “solar motorcycle” in 2026, the practical decision sits between a true solar machine with modest performance, a three-wheeled solar EV, and a plug-in electric bike they can buy today.
The trade-offs are stark. The YongLE CG gives real solar input and full motorcycle-class performance, but its 37 mph top speed and 31-mile solar range make it a commuter, not a highway bike. The Otherlab Lightfoot is the most practical urban runabout but tops out under 20 mph and is technically a scooter, not a motorcycle. Aptera offers real solar autonomy with car-class performance, but it is heavy, three-wheeled, and only available as a 2026 reservation. The Solar E-Clipse delivers genuine motorcycle speed and price-to-performance, but it is not solar-powered at all. There is no single winner because the four vehicles serve fundamentally different use cases; the right choice depends on whether the rider needs solar range, highway speed, or both.
It depends on what you are riding and where. The YongLE Risheng CG is classified as an electric moped or low-speed electric motorcycle in China and is legal on roads and bike lanes under local moped regulations. In most US states, a sub-40 mph electric motorcycle typically requires a motorcycle license or endorsement, registration, and standard equipment (lights, mirrors, horn, and turn signals).
The Otherlab Lightfoot is designed to comply with US Class 2 e-bike regulations in most states, has a top speed under 20 mph, and can typically be ridden in bike lanes without a motorcycle license. Riders should still check their state’s specific e-bike classification rules, which vary for throttle-equipped versus pedal-assist models.
The Phosgo Go5 Ultra US version, at 28 mph and 750W, sits at the upper edge of federal Class 2 e-bike limits. Several US states impose stricter rules, and Phosgo has not published state-by-state compliance documentation. Buyers should verify legality in their jurisdiction before placing a pre-order.
Aptera occupies a different legal niche. Most US states classify three-wheeled vehicles with specific weight and speed thresholds as autocycles rather than motorcycles, which means riders do not need a motorcycle endorsement to drive one. Intelligent Living previously covered Aptera’s never-needs-charging solar EV in detail when production plans first emerged. A few states still require a motorcycle license for any three-wheeler. If you are considering an Aptera reservation, check your state’s autocycle laws before placing the deposit.
Yes, but with caveats. The YongLE Risheng CG is the only production two-wheeled motorcycle currently shipping with onboard solar hardware (250W roof panel plus a wind turbine), and it is sold only in China. The Otherlab Lightfoot and Phosgo Go5 Ultra both integrate solar panels into their bodywork and wheels, but neither has documented owner deliveries at scale. The MASK Architects Solaris is the most ambitious solar motorcycle concept, with retractable circular photovoltaic wings, but it remains a design study with no production partner.
Genuine solar-powered two-wheelers range from $2,199 for a pre-order Phosgo Go5 Ultra e-bike to $4,995 for an Otherlab Lightfoot cargo scooter to “unannounced” for the YongLE Risheng CG. The Aptera three-wheeled solar EV starts at $33,200 for a Launch Edition reservation, with production targeted for late 2026. The Solar E-Clipse 2.0, often the top search result for “solar motorcycle,” is the cheapest at $5,995, but it is not actually solar-powered; “Solar” is the manufacturer’s brand name.
The Solar E-Clipse is fully street-legal in most US states and EU countries when registered as an electric motorcycle, but it is not solar-powered. The brand is called Solar Scooters UK, and “Solar” is a name, not a technology. The astronomical event (a solar eclipse) and the motorcycle brand are unrelated. If you actually want a motorcycle that charges from the sun, the YongLE Risheng CG is the closest production option, sold in China with a 250W onboard solar panel.
Among motorcycles that come up when searching “solar,” the Solar E-Clipse 2.0 Race Edition is one of the most affordable at 70 mph ($6,799, 16 kW peak motor), though it is not actually solar-powered. Among genuine production electric motorcycles, the Zero SR/F (~120 mph, ~20,000), Energica Experia (~112 mph, ~29,000), and Can-Am Pulse (87 mph, ~8,999) all clear 70 mph. For genuine solar-equipped bikes, no current production model exceeds 40 mph.
Technically yes, practically limited. The YongLE Risheng CG can run on solar and wind input alone for roughly 31 miles per day in good conditions, but only at low speed and only with the roof-mounted turbine and panel both contributing. The MASK Architects Solaris concept is designed around full solar autonomy but has no disclosed daily range and is not yet a production vehicle. The physics of photovoltaic surface area on a two-wheeler’s silhouette caps real-world solar input at roughly 5-10 miles of range per day in good conditions for a typical motorcycle, with smaller vehicles like the Phosgo Go5 Ultra e-bike claiming up to 17 miles per day from wheel-integrated panels.
Solar panels themselves degrade slowly, typically 0.5-1% efficiency loss per year, meaning a quality panel still produces 80-90% of its original output after 20-25 years. The electric motorcycle components (battery, motor, and controller) follow standard EV longevity: batteries last 8-15 years depending on chemistry and care, while motors and controllers can run for decades with minimal maintenance. The YongLE Risheng CG’s lithium-iron-phosphate battery chemistry is particularly long-lived, often rated for 2,000+ charge cycles. The Phosgo Go5 Ultra uses LG 21700 cells with similar durability expectations.
The solar motorcycle market in 2026 is a story of three very different futures coexisting at once. MASK Architects’ Solaris shows what a fully self-charging two-wheeler could look like once battery and panel technology catch up with the designers’ ambitions. The YongLE Risheng CG, Otherlab Lightfoot, and Phosgo Go5 Ultra show what is actually shipping, or about to ship, today: real solar input, modest performance, and pricing that ranges from accessible to aspirational. Aptera shows what an extra wheel and a much larger surface area can do when the entire vehicle shape is rebuilt around solar capture. All three point in the same direction: a near future where sunlight is a meaningful contributor to how we move on two wheels, even if it is not yet the only contributor.

After months of waiting for a rooftop solar-and-battery system to go live, one British homeowner got an unexpected twist: the launch happened on the same day as a solar eclipse.
Instead of sounding annoyed, the homeowner treated the coincidence lightly.
In a post on Reddit, the original poster called it “a bit of a joke” and said they “can’t wait to see the impact on the panels!”
“After months of waiting, my solar and battery system goes live today… Only to be the same day as an eclipse!” the homeowner wrote.

Pennsylvania county urges state to block landfill plan to truck polluted waste liquid – The Cool Down

Schuylkill County officials formally stepped up their opposition to a landfill plan they say could leave nearby communities facing risks for years to come, according to The Republican-Herald.
Letters made public at the commissioners’ Aug. 19 meeting show the county asked the Pennsylvania Department of Environmental Protection to reject two pending requests: a permit modification for the Blythe Recycling and Demolition Site Landfill and a permit renewal for Natural Soil Products.
A central issue in the BRADS dispute is leachate, a polluted liquid created when water passes through waste and picks up contaminants.
Commissioners Larry Padora, Barron L. “Boots” Hetherington, and Gary J. Hess are asking DEP to deny BRADS’ request for a major permit change.
That change would make truck hauling the primary method for handling that liquid rather than sending it through the pipeline connected to the Schuylkill Valley Sewer Authority.
In the county’s view, that change would expose St. Clair and nearby areas to avoidable danger.

The commissioners’ letter also described a troubling record at the landfill, including odor issues, failed sump valves, litter blown off-site, and an unreported fire.
Commissioners also used the meeting to challenge Natural Soil Products. 
In a five-page letter to DEP Program Manager Roger Bellas, they asked that NSP’s municipal waste processing permit renewal be denied and included a petition signed by nearly 60 nearby residential property owners.
County officials said NSP accumulated 87 DEP violations between 2007 and 2025. 
They also raised concerns about building expansions they say occurred without permits from 2015 through 2021.
The dispute centers on odors, truck traffic, contamination fears, and whether the companies involved are following rules enacted to protect public health.
County officials say BRADS was first approved with a system that sent leachate by pipeline to the sewer authority. The commissioners argue the turn toward trucking is due to cost disputes, not to an engineering failure.
They say that putting more leachate on the road increases the risk of spills reaching highways or waterways, with potential impacts on drivers, nearby residents, and local ecosystems.
Officials also alleged that NSP’s operation may have moved beyond its original approval. 
County records, as summarized by The Republican-Herald, showed a 1992 zoning permit for a “leaf and yard waste composting facility only,” while the site now also handles municipal sewage sludge composting.
The board separately objected to NSP’s request to extend compost drying times from 30 days to as many as 75 days, warning that longer holding periods could worsen odor and pest problems.
By submitting their objections in writing, the county has created a formal record urging the DEP to reject both the BRADS permit modification and the NSP renewal.
The petition opposing NSP’s request demonstrated that nearby property owners are documenting concerns about odors and nuisances.
For BRADS, commissioners cited repeated violations and argued that safer disposal infrastructure is already in place. For NSP, they cited zoning concerns, building changes, and years of violations.
The next move rests with the DEP, which will decide whether either company receives approval to move forward under the requested terms.
“The safest and most convenient method of leachate disposal is to convey the leachate to SVSA, in accordance with permit requirements,” the letter said. 
“An accident can occur with a leachate truck and the leachate spills on the highway or spills into a stream. These are potential risks that can easily be avoided with the direct disposal of leachate to SVSA.”

Alliant Energy solar project draws farmer concerns in Winnebago County – NBC26

OSHKOSH (NBC 26) — A proposed solar project from Alliant Energy would stretch across Winnebago County, and it’s already drawing pushback from local farmers concerned about rising land costs.
The project would include at least 142,000 solar panels across 1,500 acres, with a capacity of 130 megawatts. Alliant Energy expects to lease the land in 30-year intervals.
Local farmer Aaron Radloff said the lease rates Alliant Energy can offer landowners will have a ripple effect on those who do not participate.
“Because of the rates that they are able to offer, that also artificially increases the land rent for the rest of us locals in this area,” Radloff said, “It’ll directly raise rents and land prices for me and all the other farmers in this area.”
WATCH THE FULL BROADCAST STORY HERE:
Alliant Energy Renewable Development Manager Justin Foss said the project offers financial benefits for participating landowners.
“We’ve heard from some landowners that it’s going to help them make sure they’ve got money to pay for their kids’ college. We’ve heard from some landowners that it’s what’s helping them keep that farm and the land continuing in their family so that future generations can use it once the solar is done,” Foss said.
A project study boundary map outlines the overall area under consideration. Not all land within the boundary will be used for solar panels — it represents the outer limits of where panels could be placed.
Winnebago County Executive Gordon Hintz said the county has limited authority.
“There’s no direct role for the county in a project of this scale, but clearly anything that’s in the county we have an interest in. But the regulation and oversight and approval would be at the state level with the Public Service Commission,” Hintz said.
More information about how the Public Service Commission reviews construction projects is available at psc.wi.gov.
Additional details about the solar project are available on the Alliant Energy website.
Pending regulatory approval, the project is expected to be operational by 2029. Alliant Energy will hold public listening sessions on September 22 and October 27 at Dauntless Soul Brew Company in Omro.

At Nevada's 1.8-million-panel Gemini solar farm, a rare desert milkvetch produced eight times more flowers and ten times more fruit than plants outside, because the panel rows held rain in the soil long after the same Mojave sun had pulled it from open ground – ScienceBlog.com

The solar panels meant to harness the desert's sun are inadvertently nurturing one of its rarest plants, raising questions about whether industrial sprawl might sometimes create unexpected refuges.
By
Published
Before the Gemini Solar Project was built, botanists combed its 20 square kilometers of Mojave Desert northeast of Las Vegas and found exactly 12 individuals of a plant called the threecorner milkvetch. Twelve. The species, a small, sprawling member of the pea family named for its odd three-sided seed pods, is rare enough to be under consideration for the U.S. Endangered Species Act, and it lives in loose desert sands of precisely the sunny, gently sloping kind that solar developers covet. The expectation, when 1.8 million panels went up on its habitat, was not a happy one.
The follow-up surveys found the plant had not merely survived the solar farm. It had moved in and prospered. By 2024, two years after construction, ecologists counted 93 threecorner milkvetch plants inside the fence, nearly eight times the pre-construction dozen, and the individuals growing among the panels were outperforming their wild cousins on every measure that matters to a plant.
The comparison was clean because the researchers designed it that way. A team led by Tiffany Pereira of Nevada’s Desert Research Institute tagged and tracked milkvetch plants inside the array and at an undisturbed population on federal land nearby, same rains, same sands, same Mojave sun, and followed them through the growing season, publishing the results in Frontiers in Ecology and Evolution.
The plants inside Gemini grew wider and taller. They began fruiting nearly three weeks earlier. And by season’s end the gap had become a chasm: the solar-farm plants produced roughly eight times more flowers and ten times more fruit than the plants outside, while survival rates between the two groups were statistically the same. For an annual plant whose entire evolutionary strategy is to erupt after rain, reproduce frantically and die, a tenfold difference in fruit is not a detail; it is the species’ future, banked in the seed.
The mechanism is desert arithmetic. A Mojave annual lives and dies by how long the moisture from a rain event stays within reach of its roots, and on open ground the answer is: not long. Full sun and wind strip water from bare sand within days, and the plants outside the fence grew accordingly, small, quick and conservative.
Inside the array, the panel rows changed the water budget without changing the rain. Shade cast across the ground for part of each day slowed evaporation, wind speeds between the rows dropped, and the soil held its moisture deep into spring, letting tagged plants keep stretching, flowering and setting pods for weeks after the open desert had dried down. The panels also redistribute what falls on them, their driplines concentrating runoff at the row edges. The result was a landscape that received Mojave rain but spent it like somewhere gentler.
The plant’s own preferences, mapped across thousands of microsites, tell the story with precision: 94 percent of the milkvetch at Gemini grew in the sunny interspaces between panel rows, enjoying the improved moisture without sacrificing the light a desert annual craves, while almost none, a single plant, grew in the permanent darkness directly beneath a panel. The sweet spot was not shade; it was the neighborhood of shade.
The milkvetch had help, and the help is the transferable lesson. Gemini was built under requirements to minimize disturbance in milkvetch habitat, and its developers departed from the industry’s default of blading and grading, the practice of scraping a site to bare, level dirt that destroys the desert’s seed bank along with everything else. Across much of the project, vegetation was left in place or crushed rather than removed, panels were raised over intact soil, and the buried seeds of the 12 original plants, plus decades of their ancestors’ seed rain, survived construction to germinate into the improved microclimate. The study is one of the first to measure what that gentler approach, which its advocates call ecovoltaics, actually buys, and the answer at Gemini was a rare plant population multiplying inside an operating power station.
The researchers are careful about the boundaries of the finding. One species, one site, two years; other desert plants want different light budgets, and a wetter or drier run of years could shift the balance. Panel geometry matters enough that the paper reads partly as design guidance, higher panels and wider rows as habitat parameters. But the core observation stands, and it lands on the same physics that solar developers bank on. The Mojave sun is relentless; that is why 1.8 million panels are there. The unplanned discovery is that intercepting a slice of that sun does for the ground what it does for the grid, capturing something the desert otherwise wastes. The panels harvest the light, the soil keeps the rain, and a plant with twelve survivors took one look at the arrangement and produced a decade of seeds in a season.

As summers grow hotter, we’ll need new solutions for agriculture and the people who keep this industry going. Now, a study finds that the practice of coupling solar panels with farmland, known as agrivoltaics, isn’t only cooling for crops, but for people, too—decreasing heat by several degrees for both.
Many agrivoltaics studies have investigated the pros and cons of these hybrid landscapes in specific, real-world field scenarios. This study took a different approach, using a computer model to simulate the unique microclimates that develop beneath solar panels.
“We wanted to build a model so people can test these physics and new design ideas before spending money on hardware,” say Erfan Hosseini, PhD candidate at Princeton University, and Elie Bou-Zeid, researcher in civil and environemtal engineering at the university, and both authors on the new study. The model simulated the movement of air, heat and moisture between panels, soil, and plants, and then looked at the effects on those crops, panels—and the people tending to them. 
In this case, using data from tomato farms and simulating the effect of a typical New Jersey summer’s day, the model compared open-field tomatoes with crops grown under solar panel shading, and found something extraordinary. Tomato leaves would be at least 1.84 °C cooler under a patchwork of solar panels, it found, but up to 7.56 °C cooler during the heat of the day, compared to unshaded plants. 
This cooling effect would also reduce water loss from the leaves by 22.4% per day, and by 42.6% daily from both crops and soil. In turn, the air-cooling effects of this evapotranspiration would chill the solar panels themselves by 5.6 °C, reducing heat-related efficiency losses by 15%.
 
 
Despite the shaded tomatoes receiving 47% less direct sunlight, their photosynthesis declined by 31%—a figure that was lower than the researchers expected. This suggested, as other studies also have, that the benefits of a cooler microclimate offset the productivity losses of less sun
Most uniquely, the model revealed that the overall cooling influence had a benefit for people. Farm laborers would experience this as a 4.46 °C decline in average temperatures. In the simulated scenario, installing solar panels on tomato farms brought down perceived temperatures from 39 °C to around 35 °C. 
That’s a significant reduction in a warming world. “Outdoor workers bear the brunt of this heat, and their drop in productivity has wider socio-economic repercussions,” say Hosseini and Bou-Zeid. “Our results show that shading dominates and results in improved thermal comfort, improving workers’ health, wellbeing, and productivity.”
Solar panels are emerging as a key climate solution for energy, crops, and people. But before we roll them out across farmland at large scales, we’ll need to weigh up their pros and cons. “Agrivoltaics design is not one-size-fits-all,” the two researchers say. “That’s exactly why a tool like this is needed. It lets you find out before you build your first prototype.”
“We’d welcome working with growers and developers who want to try it on real sites.”

3,100 solar panels now float on the reservoir where 35,000 Ohioans get their drinking water, on four acres instead of the ten the same output needs on land, and the mayor who proposed it in 2019 retired two years later without seeing a single float go in – Autonocion.com

By: Chema Bonilla Díaz
Published: Aug 29, at 3:00pm ET
Solar developers in the Midwest usually lose their fights at the township level. Neighbors show up, trustees pass a resolution, and the project dies long before anyone pours concrete. Ten miles southwest of Lima, Ohio, that is what finished Birch Solar 1, a 300-megawatt farm planned for 1,410 acres of cropland. The Ohio Power Siting Board denied it on October 20, 2022, the first time the board had ever rejected a utility-scale solar application.
Lima watched that from up the road. On August 12, 2026, the city energized 2 megawatts of solar panels floating on four acres of Twin Lake Reservoir, which is where its 35,000 residents get their drinking water. No county resolution, no siting case, no hearing.
The array powers the water treatment plant next door, a building that runs pumps and filters around the clock and pushes about 14 million gallons a day. That plant burns more electricity than anything else the city owns.
Lima is better known for other industry. The Cenovus refinery on the north side of town processes around 183,000 barrels a day, and the Joint Systems Manufacturing Center, government-owned and run by General Dynamics Land Systems, is the only plant in the United States that builds M1 Abrams tanks.
More than 3,100 bifacial panels sit on Ciel & Terre Hydrelio floats, tied to anchors on the reservoir bed and its banks. Power runs ashore to eight Yaskawa Solectria XGI inverters. Rain does not bother any of it, and Ohio had plenty of rain the week the array came online. The mooring lines let the whole thing ride up and down with the water level.
Other towns will copy the land math. A 2-megawatt ground-mounted system needs at least 10 acres once you allow for row spacing and service access, and the floating version covers 4 acres of surface. D3Energy, the Florida developer behind it, has now built all three of Ohio’s floating arrays, with contractor ARP Solar doing the construction on each one.
“By building on water the city already owns, Lima is generating 2 MW of clean power while preserving nearly 10 acres,” D3Energy managing director Stetson Tchividjian told Solar Power World.
Lima put in roughly $2 million of its own money on a project the developer prices at $5 million. A $2.4 million Department of Energy grant covered the largest share, money that then-U.S. Senator Sherrod Brown helped secure. Close to $900,000 more came through the Inflation Reduction Act’s direct pay provision, which lets a city with no federal tax bill collect the investment tax credit as cash.
No spam. Unsubscribe anytime. Privacy policy (opens in new window)
Mayor Sharetta Smith has said the project would not have been possible without that provision. Running the water plant costs Lima about $1 million a year.
Utilities director Michael Caprella puts first-year savings around $200,000 and lifetime savings near $10 million across an expected 15 to 20 years, he told The Lima News. Twenty years at $200,000 comes to $4 million. Closing the gap to $10 million assumes Ohio electricity keeps getting more expensive. That is a forecast.
Any town trying this now faces a harder clock. The One Big Beautiful Bill Act, signed July 4, 2025, ends the Section 48E investment credit for solar placed in service after December 31, 2027, unless construction began before July 5, 2026. That construction deadline passed six weeks before Lima flipped the switch. Direct pay itself survived the law, but it only pays out whatever the underlying credit is worth, so a municipal project starting today has until the end of 2027 to be generating.
Ohio Senate Bill 52 took effect on October 11, 2021. County commissioners can designate any unincorporated part of a county as a restricted area where large wind and solar are prohibited outright, and the siting board cannot accept an application there. Roughly a third of Ohio’s 88 counties have adopted some restriction. Richland County voters upheld bans across 11 of that county’s 18 townships on May 5, 2026, with just under 53% of the vote.
Lima’s array never went near any of it. Ohio law defines a “large solar facility” as 50 megawatts or more, and the restricted-area power reaches only unincorporated county land. A 2-megawatt array inside city limits on city-owned water sits outside both tests. That is the whole trick, and it is a boring one.
Two megawatts does not replace 300.
Lightsource bp said Birch Solar would have supplied roughly 55,000 homes. Lima’s array covers about 250 homes’ worth of annual electricity, according to WLIO, and offsets around 1,076 US tons of carbon dioxide a year, or 976 metric tons. Lima proved something smaller and more useful. A mid-sized American city can put real generation on infrastructure it already owns and skip four years of hearings to do it.
NREL has been making the land-sparing case since 2018, when its researchers estimated that floating panels on more than 24,000 man-made American water bodies could supply about 10% of national electricity generation and spare roughly 5.2 million acres of ground. That same work listed reduced evaporation and reduced algae growth as side benefits, and Lima cites both. We went through NREL’s federal reservoir numbers in more detail when Britain opened its own consultation on covering lakes with panels.
Field data is thinner than the modeling. A team led by Alexander Cagle at UC Davis sampled four American floating solar ponds twice a day across all four seasons and published the results in Frontiers in Water in October 2025. Differences in chlorophyll-a, phycocyanin, dissolved oxygen, pH and temperature between shaded water and open water were mostly minimal. One site with 4.8% coverage showed chlorophyll-a down as much as 80% under the panels in spring. A eutrophic site with 22% coverage sometimes ran higher under the panels than out in the open. The authors asked for longer monitoring before anyone banks on the water-quality benefits.
A separate 2025 study of a shallow drinking water reservoir reported benthic cyanobacteria appearing beneath a floating array, which is the one organism a water utility does not want more of. Lima’s four acres are a small share of Twin Lake, so whatever shading effect exists there will be smaller still. The array started generating on August 12, 2026. Anything measurable at Twin Lake will take seasons.
Del-Co Water finished Ohio’s first floating array in spring 2024, 1.5 megawatts and about 2,600 panels on a pond at its Olentangy Water Treatment Plant in Delaware, offsetting close to half that plant’s electricity. Monroeville, a village in Huron County, has 6 megawatts going in on its own drinking water reservoir, due online before the end of 2026 and rated at more than 7,500 megawatt-hours a year. That one will pass Lima as the largest floating array in the state.
Ownership separates the three. Gardner Capital owns the Del-Co and Monroeville systems, and the utility and the village buy the power back under long-term agreements. Lima owns its array outright, which is exactly the outcome the direct pay credit was written to make possible.
Cohoes, New York, a city of about 17,000, went further on a smaller pond, with 5,880 panels and 3.2 megawatts covering most of its 10-acre drinking water reservoir, paid for with $3 million in federal money, state incentives and $750,000 from National Grid.
The American pattern here is small, municipal and attached to a water plant. Most of the country’s floating solar sits on closed-loop water like this, as we found when a California winery floated 1,000 panels over its irrigation pond, and when Arkansas researchers put 96 panels on a rice irrigation reservoir.
David Berger, mayor of Lima for 32 years, took the floating solar idea to Power a Clean Future Ohio in 2019 and retired in 2021 without seeing a single float go in the water. City council authorized the project in 2023, crews drove the first anchors in October 2025, and the array started producing on August 12, 2026, feeding a plant that serves close to 27,000 water accounts.

InfoLink 1H26 module rankings: Top 10 suppliers post record shipment drop as market pivots outside China – Green Building Africa

InfoLink’s first half 2026 global photovoltaic module shipment ranking shows an unprecedented contraction among the largest suppliers. The 10 biggest names saw combined deliveries fall 31% compared with the same period last year, while a like for like view of the eight firms present in both 1H25 and 1H26 still points to a 30% drop. In total, the companies included in the ranking moved approximately 181.39 GW, with volumes so close at the lower end that four suppliers tied for eighth place, making 11 names in the published list.

LONGi and JinkoSolar finished level at the top. Trina Solar took third by a narrow margin, with JA Solar just behind in fourth. These four leaders accounted for around 59% of all ranked shipments, creating a clear gap over the rest. Yet the chase is tightening, as the shipment gap between the leading group and the next tier narrowed by about 4 to 5 percentage points from a year earlier. All four leaders include output from their United States module plants in their totals, with LONGi counting Illuminate USA, JinkoSolar counting Jinko Solar (U.S.) Industries, Trina Solar counting T1 Energy, and JA Solar counting American Panel Solutions in Corning.
The third tier comprised Tongwei, Astronergy and Yingli Solar in fifth to seventh. In the fourth tier, DMEGC Solar, AIKO, TCL Solar and GCL tied for eighth as their volumes differed by less than 5%, intensifying competition for position. For this ranking, TCL Solar’s data combine several brands, including HuanSheng, TCL Solar, TCL Photovoltaic Technology, SunPower, Maxeon and DAS Solar.
Three companies stand out in the movement of the list. Canadian Solar, a long time fixture, dropped out of the top 10 for the first time. That does not signal lost competitiveness. The company has been one of the few Chinese PV manufacturers to stay profitable over the past three years, sharpened its focus on the United States market, and recently started production at its US cell plant, a move that aligns with a pivot toward higher value markets.
AIKO entered the module shipment ranking for the first time. Though historically a specialist cell maker, it secured a leading position by leaning into its BC technology and an all BC module strategy, illustrating how a focused cell supplier can transform into a tier one module player.
TCL Solar now represents the combined entity of TCL Solar and DAS Solar, two brands that previously sat inside the top 10. As the industry enters a plateau phase, the established wafer specialist filled its long standing gap in cell capacity through the acquisition of DAS Solar’s brand and production assets. The merged scale and market reach have lifted TCL Solar to become the third largest BC module supplier globally, with integration expected to wrap up this year.
Policy and demand dynamics reshaped where modules went in 1H26. An export tax rebate change and a sharp drop in domestic demand in China pushed the top 11 suppliers to redirect volumes overseas. China accounted for about 39.9% of total shipments, while other markets made up 60.1%, an increase of roughly 18 percentage points from 1H25.
By technology, TOPCon remained the workhorse. Shipments of TOPCon modules made up about 83% of volumes among the top 11. BC modules also posted growth. Beyond AIKO, LONGi, JA Solar, TCL Solar and GCL all recorded BC shipments, taking total BC volumes to nearly 30 GW in the first half, or 16% of the top 11 total. HJT does not feature strongly in this list because major HJT manufacturers were not in the top 10, so the data mainly reflects technology choices by the leading module suppliers rather than the full global HJT share.
The sector is in a structural adjustment. Imbalances between supply and demand, overcapacity and elevated inventories have slowed capacity rationalisation, while end market demand faces downward pressure. These conditions are pushing companies across the chain to accelerate technology upgrades and reinforce core advantages.
Into 2026, expectations around China’s mandatory national standard on minimum energy efficiency values for crystalline silicon modules and inverters have grown, highlighting the product premium and competitive edge of high efficiency modules. With most regional markets now broadly covered, the next phase will likely reward firms that use differentiated products to reach niche segments, align more closely with customer needs and build long term stickiness, moving beyond homogenised products and price led competition.
Suppliers that balance scale with profit, shift competition from price to value and turn short term shipment gains into durable moats are best placed to outperform in the next upcycle. The industry is expected to move from unchecked capacity expansion to a phase of high quality development focused on energy efficiency and value creation.

State gives green light for 870-acre solar farm in Ingham County – Lansing State Journal

LANSING — Michigan has given the go-ahead for a nearly $100 million solar farm in southern Ingham County, the first project to move forward under a 2023 state renewable energy law that shifted approval for such projects from local governments to the Michigan Public Service Commission.
The MPSC agreed to let Chicago-based Ranger Power construct its 90-megawatt Acceleration Solar Project on 870 acres spanning Leslie, Vevay and Onondaga townships in southwest Ingham County. It also OK’d a settlement agreement between the developer, local governments and the state agency, MPSC officials said in its Thursday, Aug. 27, release.
The project will be developed mainly east of College Road and south of Barnes Road in Vevay Township, and also includes parcels in Vevay and Onondaga townships.
The settlement agreement between MPSC, Ranger Power and the three townships establishes requirements for project construction, noise control, vegetative screening, lighting limitations, prompt complaint resolution, financial assurance for decommissioning, limitations on tree clearing, and more.
The agreement also sets limitations on the project’s footprint, which will include 618 fenced acres, and lays out rules for decommissioning including removal of underground infrastructure and restoration of the land for future agriculture use.
It also includes additional funding for township legal expenses, drain maintenance, and local fire personnel and first-responder training. The company agreed to execute a collective bargaining agreement with one or more labor organizations for the project construction and maintenance work to be performed.
“The MPSC and the townships will monitor construction and operation of the project to ensure compliance, with required reports submitted to the Commission and townships,” the commission said in its release. “That includes annual reports on energy production, complaints, maintenance, and financial assurance through the life of the project.”
Ryan Wardin, spokesman for Ranger Power, said construction should begin in the first quarter of 2027 and operations should begin in mid-2028.
Gov. Gretchen Whitmer said in a statement that Michigan is leading the way on the future of clean energy.
“This project will bring tens of millions in investment and more than a hundred good-paying jobs to Michigan communities,” she said. “It’s the very first project sited under the historic clean energy bill package I signed in 2023, which is helping us improve the grid, lower electricity bills, and build, baby, build more solar panels and wind turbines across Michigan.
“Let’s work together to grow our economy, protect our air, land, and water, secure our energy independence, and build a bright future for Michigan.”
Supervisors John Lazet of Vevay Township and Phil Hutchison of Onondaga Township could not be reached for comment.
Dallas Henney, Leslie Township’s supervisor, has been critical of the solar project and said earlier this year the legislation “pretty much took it out of our hands.” So he and the the other supervisors did what they could, Henney told the State Journal on Friday, Aug. 28, to get the best deal for their constituents.
“The process was tedious, which most government processes are,” he said. “Obviously, it was going to happen. It is what it is.”
Ranger Power’s release included a statement from Lazet.
“Following the filing of an application with the MPSC, the Township is grateful that Ranger Power was willing to sit down and listen to the quality of life concerns we had,” Lazet said. “We found Ranger Power to be thorough, detailed, competent, and open to township input. The result being an agreement that we feel is in the best interest of both the township and the Project.”
Ranger officials said Acceleration Solar is expected to bring up to $136 million in investment to thecounty and create approximately 150 jobs during construction. There will be a handful of long-term, full-time operations and maintenance positions.
The company said the project will generate substantial tax revenue, with an estimated $8 million going to Ingham County, $5.1 million to the Ingham Intermediate School District, $4.6 million to local schools, and $7.3 million in combined revenue for township millages.
“Today’s decision demonstrates what can be accomplished when communities, project developers, and state leaders work together toward a shared goal,” said Paul Harris, Ranger Power’s co-founder and president. “We are grateful to the community members and leaders of Vevay, Leslie, and Onondaga townships for their thoughtful engagement throughout this process. Acceleration Solar will deliver significant investment and employment opportunities while supporting Michigan’s long-term energy goals to provide the cheapest power available.”
Ranger Power promised in the release to maintain close coordination with the three townships, Ingham County, residents and state officials as Acceleration Solar progresses. This continued engagement is to include regular construction updates, pre-construction coordination and resident input on preferred visual screening.
DESRI, Ranger Power’s New York City-based partner on projects across the upper Midwest, will assume project responsibility at the start of construction and continue community engagement throughout Acceleration Solar’s buildout and operations.
Ranger Power’s Acceleration Solar application was the first filed with the MPSC after legislators approved Public Act 233. The MSPC’s website shows the agency has granted a certificate for Acceleration Solar and it continues to review six complete applications.
Walker Road Solar Farm LLC has voluntarily withdrawn its application to use about 1,600 acres for a solar farm in Bingham Township, near St. Johns.
MPSC records show Walker Road Solar Farm LLC voluntarily withdrew its application.
In January, local residents crowded the Bingham Township hall to protest and raise concerns about the project that a company official said would produce 150 megawatts of clean energy, which is enough to power about 28,000 homes.
The township board did not have a vote in the matter.

China Deploys World’s First 100-kW Bamboo-Built Offshore Solar Platform – Marine Insight

China has deployed a 100-kilowatt floating solar platform made from engineered bamboo off the coast of Yantai in Shandong province.
The platform, called Jilin-2, is designed to test whether bamboo can replace the steel and plastic normally used in offshore floating solar projects.
It uses composite bamboo tubes and pipes instead of the steel or high-density polyethylene (HDPE) used in most floating solar platforms.
Jilin-2 will supply electricity to a demonstration project that produces ammonia, hydrogen, and methanol.
Developers will also monitor the platform to see how the bamboo structure holds up at sea. They will check its performance in corrosion, high humidity, salt spray and ultraviolet radiation, as well as its resistance to long-term fatigue.
Jilin-2 was jointly developed by the CIMC Offshore Engineering Research Institute, China Forestry Group Corporation and Beijing Forestry University. It follows an earlier 10-kW bamboo floating solar prototype, Jilin-1, which was launched in 2023.
Yantai CIMC Raffles Ocean Technology Group announced the new platform in June. The company said using bamboo-based materials could lower the environmental impact of offshore structures compared with conventional steel and HDPE designs.
Bamboo platform
Jilin-2 uses bamboo-wound pipes for its main support structure. It also uses “Sea Bamboo Pipe”, a fibre-reinforced wood-bamboo composite developed by Beijing Forestry University.
The pipes are designed to provide both buoyancy and support for the platform. The bamboo and wood fibres were modified to help them withstand marine conditions, according to Beijing Forestry University professor Qi Chusheng,
Qi told China Green Times, an official forestry trade newspaper, that the materials were designed to withstand corrosion, high humidity, salt spray and ultraviolet radiation.
The platform will be monitored over time to check its durability, adaptability and resistance to fatigue.
The results will help understand if similar wood-bamboo materials can be used in offshore power plants, marine energy islands and marine ranches.
Marine ranches are areas of the sea where marine life is cultivated and ecosystems are restored. China has been developing them to support food security through sustainable seafood production.
10-kW prototype to megawatt scale
Jilin-2 has ten times the capacity of the Jilin-1 prototype, which had a capacity of 10 kW.
The developers plan to build a megawatt-level bamboo-based project. They also want to promote the use of bamboo-based materials in marine applications.
China has been expanding offshore solar projects along its coastline as it works toward its goals of reaching peak carbon emissions by 2030 and carbon neutrality by 2060.
In December, a 1-gigawatt offshore solar farm was brought online off Dongying in Shandong. State-owned developer CHN Energy described it as the world’s largest offshore solar farm.
Most floating solar systems use steel or plastic structures along with buoyant floats. Jilin-2 uses engineered bamboo and wood composites instead.
The 100-kW platform will show how well the bamboo structure performs during long-term use at sea.
China’s growing use of bamboo
The project is part of China’s effort to find more uses for bamboo and cut the use of some plastic products.
China introduced an action plan in 2023 to replace plastic with bamboo. The initiative was also included in the country’s latest forest and grassland conservation plan released in July.
Bamboo is a fast-growing woody grass found naturally across Asia, Africa, and Central and South America. It is used as a building material because it is lightweight, flexible, durable and strong.

Norwegian engineers built a floating solar system that survives 11-foot waves by bending with the ocean like a net rather than fighting it – Energies Media

Energies Media
Floating solar works remarkably well — until the water stops cooperating. On calm reservoirs and sheltered lakes, conventional systems perform reliably. But push them into choppy inland waters or nearshore environments, and they struggle to survive the load.
That boundary has quietly constrained the industry for years. Now a Norwegian company says it has crossed it — with a system independently verified to handle waves that would overwhelm anything currently on the market.
Floating photovoltaic power has gone from novelty to near-mainstream in roughly a decade. Installations have multiplied across Asia, Europe, and the Americas, turning reservoirs, quarry ponds, and irrigation lakes into productive energy surfaces. The growth has been genuinely impressive.
It comes with a quiet asterisk, though. Conventional floating solar systems are engineered for calm, sheltered water — reservoirs and irrigation ponds that offer predictable, gentle conditions, exactly what rigid pontoon-based platforms need to stay intact and generate power reliably over a multi-decade lifespan.
Move beyond those protected environments, and the physics become unforgiving. Choppy inland lakes, open reservoirs exposed to prevailing winds, and nearshore coastal zones subject floating arrays to hydrodynamic loads they simply aren’t built to absorb. Most of the world’s wave-prone water surfaces have stayed off-limits as a result.
That geographic constraint has quietly capped the industry’s potential — particularly in land-scarce regions where water surfaces represent one of the few remaining deployment options. Industry observers have increasingly identified exposed waters as the critical next frontier: the unlock that could take floating solar from a useful niche to a large-scale contributor to the energy transition.
Fred. Olsen 1848, a Norwegian company, developed Brizo specifically to operate where conventional floating solar can’t. The system’s core design insight is straightforward but consequential: instead of building a rigid structure that resists wave energy, Brizo moves with it.
The technology uses a flexible rope-mesh and tensioning system that lets the entire array articulate as waves pass beneath it — bending and recovering rather than bracing and cracking. Think of the difference between a wooden raft and a fishing net dropped over a swell. The net survives because it conforms; the raft survives only if the water stays flat.
That design philosophy translates into a verified operational envelope of significant wave heights up to 3.5 meters — roughly 11 feet, well beyond what conventional floating solar systems are rated to handle. It opens up a meaningfully different category of deployment sites: nearshore marine locations and wave-prone inland water bodies, both representing large, largely untapped surface areas the floating solar industry hasn’t been able to access until now.
Verification from DNV — one of the world’s leading independent technical assurance organizations — isn’t a marketing label. It’s a structured, methodology-driven review conducted against DNV-RP-0584, the recognized recommended practice for floating solar systems.
DNV’s assessment of Brizo covered design methodologies, hydrodynamic load assessment based on physical model testing, structural behavior, and testing procedures. That scope matters. The review examined not just whether the system looks sound on paper, but how it actually performs under simulated wave conditions — a distinction that’s everything to project developers, investors, and lenders.
The floating solar industry has a term for what this kind of verification unlocks: bankability. A technology carrying independent third-party validation is one that financiers can underwrite with greater confidence, because a credible external party has assessed the technical risk. As Fred. Olsen 1848 noted, the successful review “supports the BRIZO bankability and commercial deployment at scale” — reducing perceived technology risk and building the stakeholder confidence needed to move projects from demonstration into real commercial implementation.
The case for wave-resilient floating solar isn’t purely technical — it’s also geographic and economic. Many regions face simultaneous pressure from land scarcity, competing land use, and strained grid infrastructure. Water surfaces, where available, offer a way to add renewable generation capacity without displacing agriculture, housing, or ecosystems.
DNV’s Senior Vice President Prajeev Rasiah framed the stakes directly: floating solar is “entering a new phase of maturity, where the industry must move beyond sheltered waters to unlock meaningful scale.” Technologies capable of operating in exposed environments, he noted, could significantly expand the addressable market for floating photovoltaics globally. Countries with limited flat land but long coastlines or large open lakes stand to benefit most — for those geographies, a verified wave-resilient system isn’t a nice-to-have. It’s potentially the difference between floating solar being viable or irrelevant.
The DNV verification positions Brizo for its next concrete step: pilot project announcements. The bankability case is established, the technical foundation independently reviewed. What follows is translating a verified design into operating hardware on actual water.
Commercial deployment at scale is the stated milestone beyond that. Each pilot project that performs as designed adds real-world evidence to the technical case DNV has already reviewed — compounding confidence among developers and investors considering subsequent commitments. Brizo also arrives amid broader maturation across the floating solar sector, where specialized designs for cold climates, vertical configurations, and wave-exposed environments signal an industry diversifying past one-size-fits-all solutions toward purpose-built systems for specific conditions.
Watch for project developer and investor commitments as the first real-world Brizo deployments take shape. Those announcements will be the signal that a verified design has cleared its final hurdle — moving from a promising engineering solution into a proven piece of the global clean energy mix.

A drone fleet is being built to pull sunlight back onto solar panels by breaking up the cloud deck overhead, and the engineer selling it spent his master's degree doing the opposite, spraying seawater to make clouds more reflective and cool the planet down – Autonocion.com

By: Luis Reyes
Published: Aug 29, at 1:30pm ET
Clouds cost solar farms money, and the industry treats that the way it treats sunset. The forecast says overcast, the plant makes a fraction of its clear-sky output, and the financing model already assumed it would.
Meteoric Technologies showed up on August 21 with a different plan. The company wants to send fleets of autonomous drones up into the cloud deck above a solar farm, mechanically change the water droplets that make that deck reflective, and hand some of the lost sunlight back to the panels underneath.
No silver iodide. No chemicals at all.
Two Cambridge-trained engineers run it out of San Francisco, Y Combinator took it into the Summer 2026 batch, and the entire company is those two people. The pitch is enormous and the published evidence fits in a paragraph, so let’s go through both.
In its Y Combinator launch post, the company says low and mid-level overcast cuts incoming sunlight by 73 to 82 percent while it sits overhead, citing a 1980 paper in the journal Solar Energy. CEO Mete Karslioglu says the drones win part of that back. Meteoric’s own cloud-loss model puts the recovery at 10 to 30 percent of annual generation across major US grid regions, which the company values at $5,000 to $28,000 per megawatt.
A prototype dissipated an artificial cloud by 13 percent in cloud-chamber tests. That is the whole traction section.
TechSpot reported that the company has not published the chamber size or the measurement method, and Meteoric has not described how the drones alter the droplets in the first place. No aircraft has flown over an operating solar plant. Meteoric itself calls the 10 to 30 percent range a modeled estimate rather than a demonstrated result, which is the honest way to label it, and it is still the number in every headline the launch produced.
Cost is the one piece of the pitch resting on somebody else’s arithmetic. Meteoric puts electric drone flight at $30 to $60 an hour against the $2,000-plus an hour it cites for crewed cloud-seeding aircraft, and crewed seeding really is that expensive, because you are paying for a turbine engine, a pilot, and an insurance policy that covers flying a human being into weather on purpose. Drones remove all three line items. That part of the argument holds up before anybody measures a single droplet.
No spam. Unsubscribe anytime. Privacy policy (opens in new window)
Karslioglu’s research at the Cambridge Centre for Climate Repair, funded by ARIA, the UK’s Advanced Research and Invention Agency, was on making clouds more reflective using seawater spray nozzles. That work is marine cloud brightening, a solar geoengineering technique built to bounce sunlight back into space and cool the planet down.
He is now selling the same physics pointed the other way, at a smaller scale, to power plants.
Co-founder and CTO Eric Nilsson came out of microfluidic chips that control water and droplet-removal hardware for LiDAR lenses. Between the two of them, that is a decade of hands-on work on the exact question of how to make a water droplet do what you want.
Which cuts both ways. Droplet control in a lab is the credential that makes the mechanism plausible, and it is also the credential that makes the leap obvious, because a nozzle on a bench and a stratus deck over 2,000 acres of west Texas are not the same object.
That 73 to 82 percent figure is real, and it is old. It measures how much sunlight a site gives up when a low overcast deck moves over it, which is a settled piece of solar engineering. It says nothing about how much of that loss anybody can claw back, and clawing it back is the entire business.
The World Meteorological Organization’s standing statement on weather modification gets close to Meteoric’s approach in one place. Fog, the WMO says, can in principle be dispersed by enough heating or mechanical mixing, though those methods are usually impractical and expensive. Mechanical dispersal of a cloud is a recognized idea. It has just never been the cheap one.
Fog is a cloud sitting on the ground. It stays put. A stratus deck at 5,000 feet moves with the wind, regenerates from the moisture underneath it, and covers hundreds of square miles at a time, so a drone fleet that opens a hole in it has to keep opening that hole for as long as the sun is up. The WMO also notes that dispersing supercooled fog with glaciogenic material is well established, while warm cloud stays the hard case. Meteoric’s target is exactly the warm case.
Meteoric wants to work between 3,300 and 16,400 feet above ground, and FAA Part 107 caps small drones at 400 feet. Flying beyond visual line of sight still takes a visual observer or a case-by-case waiver, six years into the data-gathering meant to replace that system.
The FAA proposed Part 108, the rule that would set common BVLOS standards, on August 5, 2025. The agency reopened the comment period in January 2026, then missed its own June 2026 deadline for a final rule, and the Department of Transportation said this month that the delay is deliberate.
On August 27 the DOT announced a Phase 2 expansion of the FAA’s BEYOND program, adding up to eight new lead participants specifically to test larger drones flying above 400 feet.
Rainmaker Technology is the closest thing to a precedent, and it is not an encouraging one. The El Segundo company flies a 50-pound quadcopter with a 15,000-foot ceiling, carrying silver iodide into supercooled clouds over the mountain west. It petitioned the FAA in July 2025 for relief from the hazardous-materials rule, and DroneXL reported on August 24 that no grant or denial had appeared in the public record 13 months later. The Air Line Pilots Association filed against that petition on safety grounds.
Meteoric carries nothing, which deletes the hazmat fight. The airspace fight is untouched.
Tennessee banned weather modification in 2024. Florida followed with SB 56, effective July 1, 2025, which turns unauthorized weather modification into a third-degree felony carrying up to five years in prison and a fine of up to $100,000. The Florida statute reaches acts intended to affect the temperature, the weather, or the intensity of sunlight.
Meteoric’s product description is a system intended to affect the intensity of sunlight reaching the ground.
No party has alleged that Meteoric is in violation of any law, and the company has not said it plans to fly in Florida. Its launch post asks to hear from solar operators in Texas, the northern US, the UK and northern Europe, and from hail-suppression programs in North Dakota, Texas and Alberta.
Montana went a third way with SB 473, banning geoengineering while explicitly carving out cloud seeding, which is the kind of drafting distinction that decides whether a company like this has a market in a given state.
Solar developers are entertaining ideas like this because the alternative is the interconnection queue. Berkeley Lab’s Queued Up 2026 report counted 773 gigawatts of solar sitting in US interconnection queues at the end of 2025, down 19 percent year over year, with the median wait from interconnection request to commercial operation running past five years for projects finished in 2025.
Squeezing more out of a plant that already exists skips that line entirely, which is the same logic behind the perovskite front glass three manufacturers just signed 13 gigawatts of.
Karslioglu wrote in the launch post that the company’s “ultimate goal is to reduce the intensity of severe storms and hurricanes.” Meteoric targets its first storm operation for late 2028, one year after the first large-scale cloud-clearing flight.
The WMO’s answer to that is one sentence long: no generally accepted evidence suggests that tropical cyclones can be modified at all. The organization goes further on the general case, saying weather systems carry so much energy that eliminating severe weather is impossible, and that technologies claiming large-scale or dramatic effects should be treated with suspicion.
That is a UN agency writing about the category, not about Meteoric, and the company has not claimed to have solved it. It has claimed it intends to try.
Between those two positions sits the thing solar operators actually have to price, which is weather they cannot control. Two Minnesota arrays swapped gravel for prairie and watched native bee populations climb twentyfold in five years.
Texas farms now tilt their panels to 77 degrees when hail crosses a 30-mile line, and insurers price the ones that duck differently from the ones that don’t. German scientists spent this spring hauling LiDAR into the UAE to test whether a big enough solar farm can brew its own rain clouds. Meteoric is the first outfit proposing to go the other direction and take the cloud away.
Meteoric has put a date on the only test that settles any of this. The company says its first large-scale cloud-clearing flight happens in 2027, at a solar farm it has not named, with a drone it has not shown. Until somebody outside the company measures what comes out of a real overcast deck, the number on the record is 13 percent, in a chamber, posted August 21, 2026.
Did we nail it or blow it?

Trending:
“Climate change is not one condition among many; it’s the backdrop condition to them all,” said Angela Lipanovich, a clean energy attorney with Estriatus Law, at a recent event. It has stayed with me.
Climate change may be global in scale, but on California’s Central Coast, we experience its consequences close to home, in our coastline, our weather, our power grid and the rising costs of keeping our homes and businesses running.
History reminds us that meaningful change often begins through local leadership, innovative partnerships and people willing to work together toward a common purpose.
As Santa Cruz County staff work to take practical steps through the county’s Climate Action and Adaptation Plan, progress is being made toward reducing climate impacts.
The county has established ambitious goals that include reducing greenhouse gas emissions, increasing clean electricity, encouraging electric transportation, expanding energy efficiency and developing local microgrids that can provide greater resilience during emergencies and power outages. These strategies are interconnected. Every rooftop solar installation, battery storage system and locally generated kilowatt helps strengthen our ability to adapt to an increasingly uncertain climate.
But successful climate action requires more than government planning. It requires community participation and, increasingly, community ownership.
That is why the launch of SolarWAVE Action comes at such an important moment.
SolarWAVE Action is a new Santa Cruz-based nonprofit dedicated to helping Californians take a more active role in shaping our clean energy future. Its mission is simple but powerful: to empower homeowners, businesses, schools, farms and multifamily property owners to participate in clean energy ownership while advocating for policies that make renewable energy more accessible and affordable. The timing couldn’t be better.
Last year, Lipanovich and her SolarWAVE co-founder, Jenny Folkesson, a data scientist, proved what can happen when different kinds of experts come together around a common problem. Working with Scudder Solar, the Santa Cruz Area Chamber of Commerce and Assemblymember Gail Pellerin, they built the data-driven case for Assembly Bill 1104. The legislation removes unnecessary regulatory barriers for private businesses and organizations installing solar projects. By cutting red tape, the law opens the door for more local investment in renewable energy.
While legislative changes often sound technical, their impact is anything but.
When a local school, nonprofit, farm, apartment complex, homeowner or business installs solar, it does more than generate clean electricity. It lowers long-term operating costs, improves energy resilience, reduces greenhouse gas emissions and keeps more dollars circulating within the local economy instead of leaving the community through rising utility bills. Those savings can be reinvested into employees, services, housing, education and local economic growth.
Energy spending is inevitable. The question is who owns the infrastructure that produces our energy and where the benefits of that investment go. Local ownership creates local resilience.
Communities become stronger when they have greater control over their own energy future. Rather than relying solely on large, centralized systems, distributed renewable energy allows smaller entities to become active participants in building a cleaner, more reliable electric grid. That sense of ownership matters.
For decades, environmental conversations have often focused on what individuals should give up. Drive less. Use less. Consume less. Those actions remain important. But the clean-energy transition offers a different story: not simply asking people to consume less, but giving them a chance to own more, produce more, save more and have more control over the energy systems they depend on.
For those of us who care deeply about our coastline, climate action is about reducing emissions and preserving the natural resources that define our quality of life and support our local economy. It is about ensuring that the communities that make up the Central Coast are prepared for the changes ahead.
That is why organizations like SolarWAVE Action are so important. They bridge the gap between policy and people, helping communities understand new opportunities, advocating for smart legislation and creating pathways for more Californians to participate in the clean energy transition. Santa Cruz County has long been a place where environmental innovation takes root, and SolarWAVE Action represents the next chapter in that tradition.
SolarWAVE Action’s launch party set for Sept. 17 will bring together people interested in the future of clean energy. It will be an opportunity to consider the larger question: What role do we want to play in building the energy future of the places we call home? Climate action becomes more powerful when communities don’t just consume energy, but when they own part of the solution. Visit their website at solarwaveaction.org for more details.
The decisions we make about energy today will shape the health of our coastline tomorrow. When we invest in cleaner, locally owned energy, we are also investing in the communities and marine environment that define life on the Central Coast. Because protecting our climate begins with strengthening our communities, and there is no better place to start than in our ocean backyard.

BlueWave to update stormwater data for Northfield solar project – Greenfield Recorder

Greenfield Recorder
Sign up for the Recorder’s FREE morning newsletter and get essential news each day.
NORTHFIELD — After hearing from experts in water resource management who called for updated data, the Planning Board decided to continue its public hearing on a solar array being proposed for Pine Meadow Road to Tuesday, Sept. 1.
The proposal by BlueWave Solar calls for a 4,316-panel solar array within a fenced-in area, and while the company currently does not have a farming contract executed, the proposal calls for a local partner to produce vegetables within the array. BlueWave Solar had previously gained approval in 2021 to construct a three-array, 26,000-panel, 10.9-megawatt project on the same road.
To address the board’s concerns with the solar panels exacerbating flooding, the members reached out to three experts in the field of water resource management, including Scott Horsley, who has 30 years of experience in the field and founded Horsley Consulting, Tufts University professor Jim Limbrunner who specializes in hydrology and water resources systems and hydrologist and lecturer Stephen Garabedian.
Horsley told the board that he and the other scientists used two different models to project the array’s impact on the flow of rainwater. Limbrunner used the first model, which the Federal Emergency Management Agency uses to determine that the array would increase the flow of water in the floodplain by a “minor raise” of 0.05 feet per-second during a 100-year flood event.
“That’s pretty slow,” Horsley said. “Jim (Limbrunner) did not find significant effects from the structures that are being placed in terms of how it might deflect floodwaters or raise floodwaters.”
On the web or with our app, the Greenfield Recorder provides award-winning, essential local coverage from arts and sports to breaking news and opinion. You get unlimited access to it all, including archives and our popular e-Edition.
Tad Heuer, legal counsel for the applicant, BlueWave Solar, confirmed with Limbrunner that his analysis did not determine a “floodplain-related basis” for the Planing Board to prohibit the project.
Horsley and Garabedian used HydroCAD, the second method for stormwater modeling that Horsley mentioned and the standard model for the Massachusetts Department of Environmental Protection (MassDEP)’s stormwater standards, according to Horsley. Under MassDEP’s Stormwater Management Standards, “Stormwater management systems shall be designed so that post-development peak discharge rates do not exceed pre-development peak discharge rates,” meaning stormwater management systems must not increase the flow of rainwater.
To predict whether the solar array will increase flow, scientists use “curve numbers” that take into consideration the land cover on the ground. The higher the curve number, recorded as a percentage, the higher the water flow. For example, according to Horsley, the curve number for a forest that catches water through the plants that cover the land, is typically around 50%, while parking lots have a 97% curve number.
For Garabedian, the “crux of [his] critique” was that the data BlueWave provided followed a curve number for a meadow, 58%, instead of pasture, grassland or range, which has a curve number range of 61% to 79%. For his own calculations, Garabedian used the 79% curve number. According to the hydrologist, while BlueWave determined that rainwater flow would decrease by 10% in one area of the site and 27% in another area of the site after the array was built, Garbedian’s analysis found that the development of the array would increase flow by 15% in one area and 66% in another area.
“Given that we don’t know how they’re going to farm this, what is going to be done as far as the soil’s concerned, how they’re going to manage it, it is my professional opinion that the most conservative number for this given land cover should be applied,” Garabedian said. “That is the bottom line here, I feel that they are not using a conservative approach, if they do, they will see that there is the potential for the design as it is now to not meet standard 2.”
Instead, Garabedian said the field analysis BlueWave Solar provided reflects the “best-case scenario.”
Garabedian said the worst-case scenarios can occur. As an example, he mentioned the $1.14 million settlement solar company Dynamic Energy Solutions LLC paid after the office of Gov. Maura Healey, who was the attorney general at the time, alleged that the company disregarded “fundamental pollution control requirements” for construction sites under federal and state law when it constructed an 18.5-acre solar array on a steep hillside above the West Branch Mill River in Williamsburg, according to the former AG’s office.
“These failures can and do occur,” Garabedian said. “These are not hypothetical.”
According to Tad Huer, the attorney for for BlueWave Solar, and BlueWave Solar Project Director Mike Zhe, the updated plans for the project as of September 2024 propose row crops and hay under the arrays, leading Huer and Garabedian to disagree over whether the characterization of the array as a meadow and corresponding curve numbers mischaracterize the project’s effect on rainwater flow.
During their discussion, it arose that BlueWave has not provided a revised stormwater report to reflect the row crops.
Field engineer Richard Ricci agreed to create a post-development analysis incorporating the latest plans for the site of the array, the experts’ comments and the “sensitivity analysis” Horsley recommended. The Planning Board hopes to review the new numbers at the next hearing and further discuss the three experts’ responses.
During public comment, John Buxton, an abutter of the array, listed rainfall data from past flooding in Northfield, including six inches of rainfall during the 2023 flooding and six inches of rainfall over only two days during Tropical Storm Irene, according to Buxton. During the 2023 flooding, Buxton said he was ready to evacuate his home, with his family’s “few personal items that [they] cared about most” packed.
“There’s at least the opportunity for a reasonable denial (of a solar array proposal) where necessary to protect public health, safety and welfare,” Buxton said.
He emphasized the words “to protect.”
“You don’t have to prove it’s a threat, just use your best judgment to protect the public,” Buxton told the Planning Board. “Am I part of the public? Is my family part of the public?”
The next hearing for the proposed solar array will take place on Tuesday, Sept. 1 at 6 p.m. in the Town Hall and over Zoom.

COHEN: No, MIT, ‘Clean Energy’ isn’t the future — nor is it really clean – The North State Journal

Is the world still transitioning to green energy in the era of Donald Trump and in the midst of, yet again, geopolitical unpleasantness in the oil-rich Middle East?
While climate activists bewail the Trump administration’s embrace of fossil fuels and its corresponding disdain for solar panels and wind turbines, a new report released by the Massachusetts Institute of Technology’s Center for Energy and Environmental Research says greener days may yet be in our future.
The report, “Glass Half-Full: Building a Decarbonized U.S. Power Sector,” sees a green light at the end of Trump’s dark tunnel of dismantling Biden-era climate policies. Focusing exclusively on electricity generation over the next decade, the report uses a mathematical model to compare how much “clean power” will survive the Trump administration’s phase-out of wind and solar subsidies and its scuttling of other green-energy initiatives with what would have been produced under Biden-era climate policies.
According to the model, the energy transition is alive and well, with about three-quarters of the “clean electricity capacity” that would have come online under the Biden-era Inflation Reduction Act and power plant regulations surviving the Trump onslaught. Yes, onshore wind power will take a hit, and other decarbonization initiatives will be delayed.
But the headwinds that the vaunted transition from fossil fuels to renewable energy is encountering show no sign of letting up. A recent report from the BlueGreen Alliance, a partnership between labor and environmental organizations, found that the 2025 One Big Beautiful Bill Act and other Trump energy initiatives have already delayed or canceled 223 wind and solar projects representing at least $82 billion in capital investment and 111,000 green-energy jobs. While a few coastal wind facilities survive, since March, developers have canceled five leases for offshore wind projects in coastal California, New York, Maine, Louisiana and North Carolina valued at more than $3.9 billion. In accordance with agreements developers negotiated with the Trump administration, most of that money will be redirected to oil and gas projects, geothermal development and upgrading the power grid.
Furthermore, “deep decarbonization” has been aggressively pursued in Europe, with disastrous results. “From 2015-2025, the first decade of the Paris Agreement on climate change, global energy consumption rose by more than 14%, with sharply contrasting dynamics,” notes Samuel Furfari, professor of energy geopolitics at the Université Libre de Bruxelles. “Europe’s decrease in energy use is no triumph of ecological heroics but rather the outcome of the assault of the EU Green Deal on competitiveness and its predictable deindustrialization and economic decline.”
Citing a recent Energy Institute report showing fossil fuels make up 86% of global primary energy consumption, with wind and solar accounting for just 3%, Furfari, writing in The Center Square, throws cold water on the idea of an energy transition. “The dominance of fossil fuels in the world energy system persists even as wind and solar, expensive and intermittent, expand. The world is undergoing an energy addition, not a transition, as new technologies supplement the growing capacity of legacy sources.”
Japan, the world’s fourth-largest economy and once a champion of decarbonization, has responded to the recent Middle East energy bottlenecks by reducing its liquefied natural gas (LNG) imports from that troubled region (while increasing LNG imports from the U.S.), ramping up coal-fired generation and restarting nuclear power plants. Wind and solar power, along with battery storage, are being pushed aside.
In addition to failing to meet the soaring global demand for affordable and reliable energy, what is billed as “clean energy” — in the MIT report and elsewhere — isn’t really clean. Wind turbines and solar panels may not produce carbon emissions, but they do create waste — lots of it. Disposal of giant wind turbines in landfills is often the only way to deal with equipment that is no longer serviceable.
“Blades are frequently buried in fragments in several landfills throughout the Great Plains, transforming sites in Wyoming, Iowa, and South Dakota into wind turbine graveyards. By 2050, the cumulative decommissioning material from wind turbines could reach 133 million tons,” noted Ariel Cohen in Forbes.
Out-of-service solar panels, laden with lead, cadmium and other heavy metals, pose their own environmental problems. According to the U.S. Environmental Protection Agency, by 2030, the nation could have as much as 1 million tons of solar panel waste on its hands.
These not-so-clean, weather-dependent energy sources will never be more than bit players in today’s fast-moving, technology-driven industrial revolution.

Solar program aims to help Bloomington residents reduce energy costs – WEEK | 25 News Now

BLOOMINGTON (25News Now) – A new partnership for the City of Bloomington aims to help residents save money on their utility bills.
The Community Solar Campaign brokered by The Stone River Group is a collaboration between the city and PowerMarket, bringing community solar to more people across Central Illinois.
“The Community Solar Program, it’s a statewide program that is specific in the Ameren territory. There are developers that have installed large solar installations that allow residential and small commercial customers to take advantage of these solar credits that are produced,” said Justin Cheger, vice president of operations for The Stone River Group.
“And the way that the program is set up, when you sign up for the program, your account gets enrolled and becomes part of that project,” Cheger said.
What is Community Solar?
According to Ameren Illinois, it is an easy way for people to help expand solar energy without having to install solar panels on their homes or businesses. All while helping consumers save money by working with community solar developers, ensuring that a portion of renewable energy is deducted from their monthly utility bill.
“Because of that enrollment, you can benefit from a 10% credit on your bill. So, the developer will apply those solar credits that they have generated to your bill. And when all of the line items on the bill come out, you’ll save 10% off of your delivery and your supply,” explained Cheger.
However, the 10% isn’t a set rate; a person can qualify for a higher percentage if they are a low-income household or individual. At that point, it could go up to 20%.
As for the cost of the program, according to city officials, it is free, and you can cancel your subscription at any time for free as well.
If you have more questions regarding the program or its enrollment process, call 1(800)253-4333 or email support@powermarket.io.
You can also visit the PowerMarket enrollment website, where you will find a tab to learn more about community solar and another section where you can contact them.
