It was a weird morning. I woke up, let the dogs out, then ran out to do some errands. Once I was back home, I headed straight to the garage and turned off the main circuit breaker. Not what you’d normally do upon returning home, right?
When it came to testing the EcoFlow Delta Pro Ultra X , — DPUX for short — and the EcoFlow Smart Home Panel 3, I had a unique problem: My house basically never loses power. I live in the suburbs of Chicago, where natural disasters don’t really happen, and my power lines are buried, so weather doesn’t affect them either. That left me with only one choice: I had to simulate my own blackout. 
Creating my own blackout was pretty easy, actually. I have a normal breaker box in my garage, with an EcoFlow Smart Panel 3 installed as a subpanel. So to simulate the blackout, I only had to kill the breaker that fed the panel.
More from CNET
But let’s back up here (no pun intended). I’ve been using EcoFlow hardware — a smart panel and battery backup — since the winter of 2023. I originally had a Delta Pro Ultra and Smart Panel 2 installed in my home that winter. The units I’m testing now are the next generations of that hardware. 
In the purest case of irony in recent memory, my home actually did lose power just last week — and I wasn’t home for it. I was shopping and got a notification on my phone indicating that the battery was running low. By the time I got home, the grid was back up.
The Smart Panel 3 is a huge improvement over its predecessor. The smart panel can accommodate up to 32 circuits, which is more than enough for my 100-amp home. You’d have to check your local ordinances and codes — and I am not an electrician — but I believe you could have the Smart Panel 3 installed as a main panel if you wanted. The main reason I had it installed as a subpanel is that the Smart Panel 2 that preceded it was not capable of acting as a main panel. When it came time to install the Smart Panel 3, rewiring the entire setup would have been a headache.
Speaking of the installation, my panel was installed by an EcoFlow-certified electrician. The company has a number of contractors nationwide who are trained to install this gear. That’s a stark contrast to my initial installation. My first electrician, who installed my previous system, needed to consult the reviewer’s guide to help with the installation.
Anyway, feeding the Smart Panel 3 is the DPUX. This is a pretty large battery and inverter, roughly the size of two of the best large coolers stacked on top of each other. It rolls around on wheels, so you could, in theory, wheel it out into your front yard to power something if you needed, but its main purpose is to supply power to your home.
The Smart Panel 3 gives you a ton of data and control over your power. I do not have a solar setup, but one way a system like this could help you is by charging via solar during the day and powering your home at night. You could also configure the Smart Panel and the DPUX to provide power to your home when rates are peaking and switch back to the grid when rates are lower.
I wanted to test how things would go if I lost power completely. I shut off the breaker at 8:53 a.m., then I simply went about my day. No one in my family noticed when the power dropped out — the DPUX can switch on and provide power in about 20 milliseconds. It wasn’t even enough of a drop to force a reboot of my computer or modem. I sat down at my desk and started doing my job.
The EcoFlow app lets you control a lot of the power in your home. You can turn circuits on and off as needed. When your battery kicks in, your circuits can be prioritized into three categories: Must Have, Nice to Have and Not Necessary. This allows you to shut down unnecessary circuits and avoid draining more power than needed. The app will even estimate how long the battery will last with each category enabled. I have my “Nice to Have” circuits set to shut down when the DPUX’s charge falls to 50% to help extend battery life. In this test, my DPUX reached 50% around 1:00 p.m.
I had two circuits set to shut off at that point, only for testing purposes, and it worked like a charm. I didn’t leave them off for two reasons. First, I wanted to see how long this battery would last under extreme circumstances. Second, I need to chat with my electrician because the labels he gave me don’t seem to match what is actually being powered. So, you know, whoopsie.
When the battery reached 50%, I only had two circuits shut down, one of which was my dishwasher, which I wasn’t planning to run anyway.
Through the app, I was able to monitor how much power I had left and generally keep an eye on things while I worked. I finally switched the breaker back on when the battery reached 19%, which was at the 7-hour, 51-minute mark. That’s not bad, considering it got me through a full workday with juice to spare.
Throughout the day, I was powering my refrigerator, a smaller beverage cooler, two electric coolers in my living room, plus all the lights, TVs and computers throughout my home. My computer tower is a Legion Tower 5i with a GeForce RTX 4070 with three monitors, so you could say my office uses a fair amount of power on its own. If I had been more conservative — for example, switching to a laptop, turning off some lights or disabling the fuses for the bedrooms in the house — I could have gone much longer. 
All this comes at a price, of course. My system, as reviewed, costs $10,999. For that, you get an inverter, two batteries and the Smart Home Panel 3 (a $3,299 unit on its own). That doesn’t include installation. You can also add additional batteries if you’re so inclined, and they’ll work with solar hookups if you have panels. The new generation of hardware and installers feels like everything got upgraded. That’s rare in a tech review, and happy news.
By comparison, the Tesla Powerwall 3 starts at 13.5 kWh, which is more than the 12.28 kWh that the DPUX offers. The Anker Solix E10 offers a similar package with the power module, two batteries and a smart inlet box for $6,699, which is a lot less expensive than the package I reviewed. All of these systems are expandable, with EcoFlow’s and Anker’s being stackable. The Powerwall, in the meantime, is expandable, as long as you have the wall space.
Overall, I’m very satisfied with how this battery performed. With my current setup, I anticipate being able to last a full day without power, and I can expand my system in the future as needed. If my house ever loses power for real, I’ll certainly be more conservative with power, but I’m confident that I’ll have a lot of lead time before things really go dark.

In Alabama, a solar newbie with a $400 summer bill for a doublewide gets told to insulate – The Cool Down

An Alabama resident preparing to inherit a doublewide turned to social media for beginner solar advice after seeing their summer electricity bills hit $400. 
But instead of panel recommendations, the conversation quickly focused on the home’s efficiency.
In a Reddit thread on the site’s r/SolarDIY forum, the original poster said they were just getting started with solar and wanted guidance on a setup for a doublewide in Alabama with very high summertime power costs.
OP wrote, “I’m very new to solar,” and added, “our doublewide runs a $400 power bill in the summer and I’m supposed to inherit it very soon. Any tips and solar system recommendations greatly appreciated!”
With energy prices through the roof, there’s never been a better time to go solar — and EasyHome can help you find the best prices from the best installers in your area.
EasyHome takes the guesswork and headaches out of energy upgrades by showing you estimated savings from a network of vetted local partners. To get started, just enter your ZIP and share a few details about your home — seeing your estimate is really that easy.
The top response did not start with panel sizing or product picks. Instead, it treated the steep seasonal bill as a sign that improving insulation and cutting cooling waste could make more sense before paying for a solar system large enough to cover that level of use. The user wrote, “You need to insulate the trailer as much as possible. It’s leaking the AC out.”
The same commenter added, “If you are in a park with a small lot you’ll have to emphasize using less power before trying to generate more.”
Essentially, if a doublewide is losing too much cooled air, adding solar does less to solve the real problem. In that case, the homeowner may end up needing a larger, more expensive system just to keep pace with summer demand.
The practical advice in the thread was to tighten up the home first by improving insulation and reducing cooling loss, then look at solar pricing based on lower energy use.
Still, the doublewide owner was right: going solar is one of the best ways to save money on home energy, especially once a high-usage home has been tightened up. Homeowners can try EnergySage to get free solar installation estimates and compare quotes. Those who do can save up to $10,000 on installations.
Homeowners can also use EnergySage’s solar map, which shows the average cost of a home solar panel system on a state-by-state level as well as details on solar panel incentives for each state. 
For homeowners facing steep bills, these stories show why efficiency upgrades and solar planning often go hand in hand. 
• A new homeowner found rooftop panels still allowed a $420 first bill.

China's 12 Solar Export Curbs Could Spike Prices [2026] – tech-insider.org

China’s commerce regulators have put the global solar industry on notice. On 16 October 2026, the Ministry of Commerce and the Ministry of Science and Technology jointly published proposed revisions to the Catalogue of Technologies Prohibited and Restricted from Export, and solar manufacturing is one of the biggest targets in the document. According to AP News, the draft covers 40 technologies across artificial intelligence, photovoltaics and biomedicine, and 12 of those 40 are solar technologies. For an industry that China has dominated for more than a decade, that is not a footnote. It is a signal that Beijing now treats its solar manufacturing know-how the same way it treats rare earths and advanced chips: as strategic leverage, not just export revenue.
For Australian readers, the story matters beyond headlines about trade friction. Solar panels, inverters and the equipment that makes them are deeply embedded in Australia’s energy transition, and any shift in how China licenses the technology behind that equipment can ripple through cost, supply and the pace of new manufacturing capacity anywhere outside China. This article breaks down exactly what Beijing has proposed, what it does not do, and why the next four weeks of public consultation matter more than most people realise.
Don't miss new tech stories on Google
Add Tech Insider once in the Google app and our stories appear in your news suggestions.
The proposal is not a ban on selling finished solar panels, cells or wafers overseas. China still wants to sell the world solar modules, and it remains the largest exporter of finished photovoltaic products by a wide margin. What the draft catalogue targets is narrower and, in a way, more pointed: it restricts the transfer of the manufacturing technology and the specified core equipment used to build advanced solar products, not the products themselves. Bloomberg reported that the move is designed to protect China’s technological edge in photovoltaics while US and Indian manufacturers race to build their own domestic supply chains.
That distinction, technology transfer versus product sale, is the single most important fact in this story. A solar developer in Queensland buying finished panels is unaffected. A manufacturer trying to license Chinese production lines, buy specialised reactors, or hire Chinese engineering teams to build a new factory outside China is the one who runs into the new rules.
Reporting on the draft, including coverage from The News International, groups the 12 solar entries into two tiers: outright prohibitions and conditional restrictions. The split matters because it tells manufacturers, and the countries hosting them, exactly where the line sits.
On the prohibited side, the draft lists manufacturing technology for silicon wafers 70 micrometres or less in thickness, manufacturing technology for perovskite solar cells and perovskite-silicon tandem cells, and technology for large-scale fluidized-bed polysilicon production. These three categories sit at the cutting edge of where solar efficiency gains are coming from right now. Thinner wafers cut material cost per watt. Perovskite-silicon tandems are the technology most analysts expect to push commercial module efficiency past the ceiling of today’s silicon-only cells. Fluidized-bed polysilicon production is the lower-cost, higher-throughput alternative to the older Siemens process.
On the restricted side, rather than prohibited, the draft names advanced solar-cell manufacturing technologies identified as TOPCon, HJT and XBC. These three acronyms, Tunnel Oxide Passivated Contact, Heterojunction, and back-contact cell designs, represent the technology that most of today’s highest-efficiency commercial panels already use. Restricted does not mean banned. It means exporters must register the transfer with Chinese authorities before it can proceed, giving Beijing a formal checkpoint rather than a hard wall.
The gap between “prohibited” and “restricted” is where most of the real-world impact will land, so it is worth laying out side by side.
Every one of those thresholds is deliberately industrial, not symbolic. Setting the polysilicon reduction-reactor bar at 800 tonnes a year, for example, targets the scale that makes a new polysilicon plant commercially viable, rather than catching small research-scale equipment. The same logic runs through the wafer-thickness and trichlorosilane-capacity numbers. These are not blanket controls. They are precision-cut around the specific production scales that matter to a serious competitor trying to build a full-scale solar supply chain from scratch.
China’s solar dominance was never just about cheap labour. It is built on two decades of compounding manufacturing know-how, from polysilicon refining through ingot growth, wafer slicing, cell fabrication and module assembly. Over the past five years, that know-how has become exportable in its own right, through licensing deals, joint ventures, and turnkey factory contracts sold to manufacturers in the United States, India, the Middle East and Southeast Asia who want to build solar capacity without buying every component from China.
That is precisely the channel the new catalogue narrows. Fortune framed the broader October 2026 export-control push, covering AI chips and solar power technology together, as driven by security concerns rather than a simple protectionist trade measure. Whether the primary motive is safeguarding China’s competitive lead, responding to Western chip and clean-tech restrictions with its own leverage, or both, the practical effect is the same: it becomes procedurally harder, and in three specific cases impossible, to walk a complete, cutting-edge Chinese solar production line out of the country.
This is not China’s first use of export controls as industrial strategy in 2026. Beijing has already tightened rules around rare earth processing technology and some categories of AI chips this year, arguing that the same mechanisms the United States uses to restrict semiconductor equipment exports are now standard tools of trade policy everywhere. The solar catalogue extends that same playbook to a sector where China’s lead is arguably even larger than it is in rare earths: China currently accounts for the overwhelming majority of global polysilicon, wafer, cell and module production capacity, a position built over roughly 15 years of sustained state-backed investment.
Framed against that history, the 16 October proposal looks less like an isolated solar story and more like one more chapter in a broader pattern where Beijing treats manufacturing know-how in strategic sectors as a controlled asset. Readers who have followed Tech Insider’s coverage of Beijing’s separate restrictions on AI model exports will recognise the shape of this move: a formal consultation process, a registration requirement rather than a blanket ban, and thresholds calibrated to catch serious industrial-scale transfers while leaving smaller or less advanced technology untouched.
The most immediate effect lands on manufacturers outside China who were counting on licensing the newest Chinese cell and wafer technology to leapfrog into advanced production. The United States has spent several years building domestic solar manufacturing capacity under federal incentive programs, and much of that build-out has leaned on Chinese equipment vendors and, in some cases, Chinese process licensing. India’s solar manufacturing expansion has followed a similar pattern. If the catalogue is finalised close to its current draft form, both markets face a harder path to acquiring the most efficient current-generation cell technology, TOPCon, HJT and XBC, without going through a formal Chinese government registration step, and zero path to licensing perovskite-tandem or sub-70-micrometre wafer technology at all.
That does not freeze those markets in place. It likely accelerates two existing trends: non-Chinese equipment makers and research institutions pushing harder on home-grown alternatives to TOPCon-class cell technology, and manufacturers outside China leaning more heavily on the Chinese companies that already have overseas factories and existing technology-sharing arrangements, since those relationships predate the new catalogue and may be grandfathered or handled case by case during the registration process.
To understand why this proposal carries weight, it helps to see where the rest of the world actually stands relative to China across the solar manufacturing stack.
The pattern in that table is consistent: China is not pulling back from selling the world solar hardware. It is narrowing who gets to learn how the newest, highest-efficiency versions of that hardware are actually made. That is a meaningfully different kind of control than the blanket export bans some early headlines implied when the story broke.
For the technologies listed as restricted rather than prohibited, the draft requires exporters to register the relevant overseas technology transfer with Chinese authorities before the export can proceed, and that registration requirement applies while the proposed catalogue is still pending, not just after it is finalised. In practice, that means a Chinese equipment maker or process licensor cannot wait for the consultation to close before changing how it handles a deal involving TOPCon, HJT, XBC or the specified polysilicon and edge-passivation technologies. The clock on compliance effectively started on 16 October 2026, even though the rules themselves are still a draft.
That detail tends to get lost in headline coverage, but it is one of the more consequential parts of the announcement. A company mid-negotiation on a technology licensing deal now has to build a government registration step into its timeline, regardless of whether the final catalogue ends up identical to the draft.
China’s public consultation period on the draft catalogue closes on 15 November 2026. That gives industry groups, foreign governments and domestic Chinese manufacturers roughly four weeks to submit feedback before Beijing finalises the rules. It is worth being precise about what that deadline is and is not: 15 November is when public comment closes, not a confirmed date for when final controls take effect. No final catalogue or implementation date has been confirmed as of this writing, and reporting on the story, including coverage from TaiyangNews, treats the consultation window itself as the next concrete milestone rather than speculating on an enforcement date.
Consultation periods on Chinese export-control catalogues have, in past cycles covering other sectors, sometimes produced adjustments to specific thresholds or technology definitions between the draft and final versions. There is no guarantee the 12 solar entries survive the next four weeks unchanged, particularly the capacity and thickness thresholds that determine exactly which real-world production lines get caught.
Australia is not a solar manufacturing power on the scale of China, the United States or India, but it is a major buyer of solar hardware and a country whose energy transition plans lean heavily on falling panel costs and rising module efficiency. Most of the panels installed on Australian rooftops and in utility-scale solar farms already use Chinese-made cells, and a meaningful share use TOPCon-class technology, the exact category now sitting in the restricted tier. If the final catalogue slows the global spread of next-generation cell manufacturing outside China, it does not raise the price of panels Australia buys today, since finished products are not covered. It could, however, slow how quickly cheaper, more efficient next-generation panels become available from non-Chinese suppliers, which matters for a country trying to diversify its solar supply chain amid broader concerns about data centre energy demand and grid capacity.
Australia’s own data centre and AI infrastructure boom adds another layer here. As power-hungry data centres compete for grid capacity, the pace at which cheaper, higher-efficiency solar generation comes online outside China becomes more directly relevant to how fast new capacity can be added without straining the grid further.
It is worth closing the factual section with a clear list of what the proposal does not do, since early social media reaction to the story conflated a technology-transfer restriction with a full export ban. The draft catalogue does not ban the export of finished polysilicon, wafers, solar cells or modules. It does not apply retroactively to technology already transferred before the consultation opened. It does not set a confirmed implementation date, since 15 November marks the close of public comment, not the start of enforcement. And it does not name any specific company, financial figure, or shipment volume in the reporting available at the time of publication.
What did China actually announce on 16 October 2026?
China’s Ministry of Commerce and Ministry of Science and Technology jointly published proposed revisions to the Catalogue of Technologies Prohibited and Restricted from Export, covering 40 technologies across artificial intelligence, photovoltaics and biomedicine, with 12 of those technologies specific to solar manufacturing.
Does this stop China from exporting solar panels?
No. The proposal targets technology transfers and specified core manufacturing equipment, not the sale of finished polysilicon, wafers, solar cells or modules. China remains free to export finished solar products under the current draft.
Which solar technologies would be fully prohibited from export?
The draft prohibits manufacturing technology for silicon wafers 70 micrometres thick or less, perovskite and perovskite-silicon tandem solar cells, and large-scale fluidized-bed polysilicon production.
What is the difference between “prohibited” and “restricted” in this proposal?
Prohibited technologies cannot be exported at all under the draft rules. Restricted technologies, including TOPCon, HJT and XBC cell manufacturing, can still be exported, but the exporter must register the overseas technology transfer with Chinese authorities before it proceeds.
When does the public consultation close?
The consultation period on the draft catalogue is scheduled to close on 15 November 2026. That is when public comment ends, not a confirmed date for final rules to take effect.
Has China confirmed a final version of the export control catalogue?
No. As of publication, only the draft proposal has been released. No final catalogue or implementation date has been confirmed.
Why is China restricting TOPCon, HJT and XBC technology specifically?
These are the advanced cell manufacturing technologies behind most of today’s highest-efficiency commercial solar panels. Restricting, rather than banning, their export lets China retain oversight of transfers while still allowing licensed deals to proceed through registration.
Does this affect solar panel prices in Australia?
Not directly and not immediately. Finished panels are not covered by the proposal. Any effect on Australian solar costs would come indirectly, through a slower global spread of next-generation cell technology outside China over the medium term.

Family's 1,000-square-foot off-grid cabin runs on sun, rainwater, and propane – The Cool Down

“Our cabin is so energy-efficient we only need 1.5 kilowatt-hours of energy per day.”

A TikToker gave viewers a look inside their 1,000-square-foot cabin built to run on remarkably low daily energy use.
The setup relies on solar power, rainwater, propane, and a small-home design that reduces demand from the start.
In a home tour, TikTok creator Wild North Family (@wildnorthfamily) said, “Our cabin is designed to run entirely off of the sun and rain.”
The home’s main systems include solar equipment connected to a battery bank, propane-powered appliances, a propane water heater, and a rainwater system that serves the entire cabin.
That water system is central to the cabin’s operation. As Wild North Family put it, “That means we drink rainwater, we cook with rainwater, and we bathe in rainwater.”
The video highlights several built-in ways the family cuts electricity use, especially the many windows that bring in daylight and create enough airflow to make air conditioning unnecessary.

Inside, the A-frame layout features two loft areas joined by a catwalk, with one used as a homeschool space and the other arranged as a nursery.
The family said the cabin has only one bathroom with a rainwater-fed shower, and they noted that they installed an outhouse before a standard toilet.
The off-grid setup is not just about generating power. The plan also involves storage and winter preparation, including a large pantry for food supplies, canning storage, bulk grain, and a hand-crank mill visible in the video.
They also showed a large Sunstar off-grid deep freezer they plan to stock with elk and beef.
Living farther from conventional utilities can require more planning for food, heating, and household routines than a typical grid-connected home.
With no AC, one bathroom, and a wood-burning stove handling heat, the cabin keeps amenities relatively simple.
The smaller footprint also has advantages: the creator said the compact 1,000-square-foot layout is easier to heat, while all the windows reduce the need for daytime electric lights.
For some households, that could mean lower ongoing energy use, even if full off-grid living isn’t realistic or desirable.
The cabin uses a layered approach to lower energy use. Instead of relying on a single technology, the family combines a compact floor plan, natural daylight, passive ventilation, propane systems, and efficient food storage to keep daily power use low.
Choosing a smaller living space, maximizing windows for daylight, or improving cross-ventilation are very different from building a whole-house rainwater system, but they follow the same logic seen in the video: reduce demand before adding equipment.
The setup also includes preparedness measures. Their pantry, grain storage, hand-crank mill, and off-grid freezer show one way to prepare for interruptions or seasonal challenges.
It also shows how efficiency can come from design decisions and habits, not just from adding more power capacity.
The family framed the cabin as a deliberate lifestyle choice rather than a universal blueprint.
As the creator said, “Our cabin is so energy-efficient we only need 1.5 kilowatt-hours of energy per day. Which means our current battery bank and solar system can last us up to two weeks without being recharged.”
Households are finding ways to keep daily energy use low with off-grid systems and careful planning. 
• In the Rocky Mountains, a family of five showed how 1,000 watts of solar can power an off-grid home.
• In Tennessee, an off-grid family said their energy independence has lasted for decades without regular generator use.
• After two years in a shipping container home, owners said using power differently changed daily off-grid routines.
• One off-grid family said meal planning and prioritizing battery usage helped stretch money and electricity.
• In a dry cabin, one homeowner weighed off-grid water access as a daily survival need.

Solar Spectrum Forecasts Power Ultra-Short-Term Photovoltaic Predictions With Deep Learning – Bioengineer.org

Solar Spectrum Forecasts Power Ultra-Short-Term Photovoltaic Predictions With Deep Learning
Solar power is famously fickle. A single drifting cloud can slash the output of a photovoltaic array within seconds, and grid operators who manage solar-heavy networks live and die by their ability to anticipate those swings. Now, a research team in Kazakhstan has unveiled a forecasting approach that looks at sunlight the way a physicist would: not just as a single number of brightness, but as a full spectrum of colors, each carrying its own information about what the atmosphere is doing and how much electricity a solar panel will actually produce minutes into the future.
The study, published in the journal Results in Engineering, was conducted by Madiyar Nurgaliyev, Batyrbek Zholamanov, and colleagues at Al-Farabi Kazakh National University in Almaty, with collaborators including Saad Mekhilef. The team built a complete Internet of Things measurement system on the roof of the university’s Physics and Engineering Faculty, combining a mini spectrometer, a fisheye sky camera, a pyranometer, temperature and humidity sensors, and a current sensor, all orchestrated by a Raspberry Pi 4 microcomputer that streamed data to a cloud server. Every minute throughout October 2025, the rig recorded not only how much sunlight was falling, but what colors that sunlight was made of.
That spectral detail matters more than most people realize. Photovoltaic cells do not respond equally to all wavelengths of light; silicon crystals convert blue photons and red photons with different efficiencies, and the spectral composition of sunlight shifts as clouds, aerosols, and water vapor scatter and absorb radiation unevenly across the color range. Conventional forecasting methods treat solar irradiance as a single integrated value, which means they implicitly assume the sun’s spectrum stays constant. It does not. When clouds roll in, the blue end of the spectrum can be suppressed while the red end holds relatively steady, and a panel’s output changes in ways that a simple brightness number cannot capture.
The researchers’ central insight was to split the forecasting problem into two stages. First, a deep neural network predicts how the solar spectrum itself will evolve over the coming minutes, wavelength by wavelength. Then, a second regression model translates those predicted spectra into the electrical current a solar array will generate. This two-stage design elegantly separates two sources of nonlinearity that are usually tangled together: the weather-driven changes in incoming light, and the panel’s own internal physics. The team’s hypothesis is that a solar cell’s quantum efficiency, its wavelength-by-wavelength conversion efficiency, depends only on the material it is made of, not on the season, the cloud cover, or the time of day. If that holds, then once you can forecast the spectrum, the panel’s response follows from physics rather than from a black box trained on one specific installation.
To test whether spectral information genuinely helps, the team ran a systematic horse race. Four forecasting scenarios were compared on identical footing: one using only solar irradiance and statistical cloud metrics, one adding the measured spectrum to irradiance, one combining irradiance with sky images processed by convolutional neural networks, and the proposed two-stage spectral approach. Each scenario was evaluated across six forecast horizons, from one minute out to sixty minutes, using the same metrics: the coefficient of determination R-squared, mean absolute error, mean squared error, and root mean squared error. The architectures included bidirectional LSTMs, gated recurrent units, temporal convolutional networks, and hybrid combinations, all tuned with Bayesian optimization through the Optuna library.
The results deliver a clear verdict for the ultra-short term. The proposed spectral approach, implemented with a multilayer perceptron, achieved the best current forecasting quality of all tested configurations for horizons up to roughly fifteen minutes. At the one-minute mark, it reached an R-squared of 0.9706, climbing from 0.9316 for the best irradiance-only model, and it maintained a decisive lead through five, ten, and fifteen minutes. Five-fold cross-validation confirmed the numbers, with R-squared of 0.9683 plus or minus 0.0043 at one minute and tight confidence intervals throughout. Ten independent training runs with different random seeds showed the model is robust, not a lucky artifact of one initialization.
But the picture changes as the horizon stretches out. By thirty to sixty minutes, the spectral advantage fades, and a model that forecasts from sky images, using a gated recurrent unit fed with features extracted by a ResNet-50 classifier, takes the crown, reaching an R-squared of 0.6636 at sixty minutes. The reason is physical: within fifteen minutes, the atmosphere has enough inertia that the spectrum’s recent history is a reliable guide, but beyond half an hour, cloud masses advected by wind can completely transform the radiation regime, and the spectral time series alone simply cannot see that coming. Sky images, which capture the visual structure of approaching clouds, retain predictive power longer. Notably, the researchers also found that simply bolting measured spectral features onto a direct forecasting model does not guarantee improvement, which underscores that how spectral information is used matters as much as whether it is used at all.
The team also mapped where in the spectrum the magic happens. A permutation-based sensitivity analysis revealed that the model leans most heavily on shorter wavelengths between roughly 350 and 425 nanometers, with additional peaks of importance around 470 to 530, 620 to 680, and 810 to 830 nanometers. This makes physical sense, since short-wavelength blue light is the most sensitive to atmospheric scattering, and therefore carries the richest information about changing sky conditions. The researchers also quantified how forecast quality decays with horizon, fitting the R-squared decline with an exponential function and the error growth with a quadratic one, both with fitting quality above 0.995. Error analysis across operating regimes showed that transient, fast-changing conditions are the hardest to predict, while cloudy conditions are easiest at short horizons and high-radiation conditions win out at longer ones.
The practical implications are significant for microgrid management and concentrated photovoltaic systems, where the spectral composition of direct sunlight plays an outsized role. Ultra-short-term forecasts in the one-to-fifteen-minute range are exactly the timescale on which grid operators must balance generation and demand in real time, and a forecast that separates weather effects from panel physics could transfer more readily between installations than models trained end-to-end on a single plant’s history. The approach could also benefit high-concentrator photovoltaic systems, whose multilayer cells are especially sensitive to spectral shifts.
The researchers are candid about limitations: the dataset covers a single month at a single location, so seasonal variability and geographic generalization remain untested, and sensor noise from the spectrometer, camera, and current sensor introduces uncertainty that partially mingles with model error. Future work will extend the dataset to year-round observations and additional sites, and will explore integrating spectral data with sky imagery and meteorological variables. Still, the core result stands: for the critical first fifteen minutes, the color of sunlight is a better predictor of solar power than its brightness alone, and teaching a neural network to see that color ahead of time is a genuinely new tool for keeping solar-heavy grids stable.

Duke Energy Florida opens solar site in Jefferson County – Florida Politics

Duke Energy Florida has opened a new solar facility that can power for about 15,000 homes in the Big Bend area at peak output.
The company announced the completion of the Bailey Mill Solar Center near Monticello in Jefferson County. The site’s roughly 163,000 solar panels give it a generating capacity of 74.9 megawatts.
Duke officials said the facility is expected to save customers about $250 million in fuel costs over its lifetime.
“The launch of Bailey Mill is another step toward lowering long-term energy costs for our customers,” said Melissa Seixas, Duke Energy Florida President.
“Every solar site we bring online reduces the amount of fuel we need to purchase, and those savings go directly to our customers’ bills. We’re grateful to the Jefferson County community for partnering with us to make this project possible.”
At peak performance, the facility is expected to displace 1.2 million cubic feet of natural gas each year, Duke officials said. That is the equivalent of about 15,000 barrels of oil or 12,000 tons of coal.
Bailey Mill is one of four solar sites Duke built under a 2024 settlement approved by state regulators, along with facilities in Madison, Sumter and Hernando counties. Together, the four sites are expected to save Duke’s Florida customers about $843 million over their service lives.
Duke owns and operates more than 25 solar sites in Florida, with a combined capacity of about 1,850 megawatts. Bailey Mill is one of five completed since 2025, and the company plans to add 11 more by the end of 1028.
Duke has about 2 million residential, commercial and industrial customers in Florida, most of them along the Gulf Coast or in Central Florida. The Bailey Mill site is one of the company’s few operations in the Big Bend area.
Nationally, Duke serves about 8.7 million customers, most of them in the Southeast, with others in Ohio and Indiana.

Are the peace movement and the climate movement the same thing? – The Crucial Years | Bill McKibben

It struck me the other day that ‘peace’ is a word we’re not using much at present. Our war in Iran is unpopular, for sure, but there’s not really a ‘peace movement’ to end it (though the midterm elections are in some measure a proxy for that). When we talk about it, it’s in the context of ‘forever wars,’ as in ‘what a pain for us to have to fight,’ or it’s about the way that war has raised prices. We seem barely to have noticed that we have attacked another country, killed its leaders, bombed its schools, made life as impossible as we can for its citizens, not to mention billions of other humans who are dealing not with higher prices at the pump but with no access to fertilizer or fuel.
But actually this is the perfect moment for a revival of the peace movement—because it’s easier now than ever before to imagine the rapid transition to a more peaceful world. That’s because all of a sudden we have an alternative to oil, and if you look around us, oil is the cause, the weapon, and the casualty of our current round of conflicts. More than at any point in our past, oil has become inextricably bound up in warfare, which means we could in short order move past it, in ways that I don’t think we’ve focused on clearly enough.
I write this newsletter so I can share ideas like this; if you find them useful, and if you can afford it, please take out a modestly priced and voluntary subscription. If you can’t afford it, then don’t worry about it, just read!
I’m thinking about all this because I’ve taken a day off of the campaign trail to come to Independence, Missouri (just a stone’s throw from the Kansas Senate race!). The town is best known as Harry Truman’s home, but it’s also the headquarters of a denomination, the Community of Christ, that had been unknown to me until they asked me if I’d accept their annual International Peace Award, which had gone in previous years to some of my real heroes: Dolores Huerta, Rev. James Lawson, Terry Tempest Williams, Jane Goodall.
As it turns out, the Community of Christ is an interesting group—they’re descended from the Mormons who didn’t follow Brigham Young to Utah but instead stayed in the Midwest with the family of Joseph Smith after he was killed by an armed mob. Over the years they drifted apart from their Utah brethren, until in the last generation they’ve become much closer to the Protestant mainline, indeed an avowedly progressive church, led by a woman, committed to LGBT participation, and very focused on peace. As I write this, I’m looking out on a Japanese garden, planted with a sister community in that country, in recognition of the complicated role that Independence and its most famous son played in the planet’s nuclear history; I’ve just come from a daily Prayer for Peace service. If I had to describe this group, I’d say: imagine Unitarians, except that they believe in Jesus and are earnestly Midwestern in their manners and customs. I like them very very much; they’ve built something special.
Anyway, the fact that I needed to give a talk as part of this awards ceremony got me more focused than I usually am on questions of peace, and the more I thought, the simpler my task seemed. The world is obviously at war right now; in fact, one Times columnist mused last month that World War III may already be in its early stages. Vladimir Putin is hammering civilian infrastructure across Ukraine, as his ongoing and unprovoked attack nears the five-year mark. The U.S., having attacked Venezuela and then Iran, finds itself running short of missiles and interceptors, bad news for the Saudis who are suddenly facing strikes from renegade Yemenis. There are plenty of other conflicts around the world, some military and some for the moment just running on intimidation and coercion—the U.S. siege of Cuba, for instance, which is killing silently. (In 2018, infant mortality on the island was four per thousand births, lower than in the U.S. Now, thanks to us, it’s more than double that).
War, of course, has many causes—ethnic and religious supremacy, personal ambition—but it is very simple to see the degree to which oil plays a crucial part in so many of these conflicts, as cause, as weapon, and increasingly as vulnerability.
Consider. We attacked Venezuela, holder of the world’s second-largest oil reserves—as far as I can tell there’s been no effort by our leaders to explain this in terms of human rights or democracy, but only as an effort to secure its oil supplies. Read the “fact sheet” the White House put out this summer about our purposes there:
In the biggest oil deal in world history, President Donald J. Trump has secured U.S. majority control of more than 65 billion barrels of proven oil reserves in Venezuela – vastly expanding our current U.S. territorial proven reserves of roughly 46 billion barrels. This deal secures our energy dominance for the next century—all at zero cost to the United States. The deal, signed by Secretary of State Marco Rubio and Secretary of War Pete Hegseth, gives the U.S. government powerful governance rights, economic ownership, and guaranteed low-cost off-take from a new private Venezuelan oil champion, which will be the second-largest private oil company by reserves in the world.
Our attack on Iran was somewhat more complex, clearly affected by Benjamin Netanyahu’s desire to cripple the Tehran regime (and stay out of jail) but also clearly driven by Trump’s fascination with the world’s third-largest oil and gas reserves. In March, for instance, Trump said in a social media post that
that the U.S. would hit Iran "VERY HARD TONIGHT" and would "assume total control" of Iran's oil and gas industries, including the key Kharg Island oil terminal, in the "not too distant future."
As he explained to the Financial Times,
"To be honest with you, my favorite thing is to take the oil in Iran but some stupid people back in the U.S. say: ‘Why are you doing that?’ But they’re stupid people."
And whatever the cause, oil has clearly become the weapon in this ugly and stupid war, with each side trying to close off the other’s crude traffic, in hopes of forcing economic capitulation. Trump may be in the harder place here, because he’s facing an election soon, and despite his best attempts to render the electorate impotent, it appears we will actually be allowed to vote somewhat freely, and that $6 diesel may be coming close to “mutilization of our children” as a campaign issue.
Trump’s clever response to this dilemma has been to betray the people of Ukraine. Remember, Putin was able to attack them because of his country’s oil wealth (John McCain’s classic line: “a gas station with nukes”), and he used his hydrocarbons to try and win the war early on, cutting off the supply to western Europe in an effort to get them to abandon the defense of Kyiv. Now he’s using his supply of diesel (and the lure of lots of “deals” with Trump associates) to get America to walk away from its one-time ally; Trump yesterday suspended the Lindsay Graham Act sanctioning Russian oil, in an act that even at this late date left diplomats speechless.
In particular Putin wants Trump to get Ukraine to stop attacking his oil refineries, the tactic that Zelensky has hit on during the past six months, and which is causing endless pain (and spiking EV sales) in Russia. Trump, of course, has obliged, and his main satrap (or is it the other way round?) Elon Musk has apparently literally sabotaged his Starlink system so as to endanger Ukrainians. It is oil top to bottom—cause, effect, weapon. As it is in the Gulf, where the Houthis and the Iranians target pipelines and pumping stations in Saudi Arabia and the UAE, who in turn use their oil wealth to hit back. As it is in Cuba, where our main weapon is an oil blockade.
Here’s how Trump put that one back in January
“THERE WILL BE NO MORE OIL OR MONEY GOING TO CUBA – ZERO! I strongly suggest they make a deal, BEFORE IT IS TOO LATE. Thank you for your attention to this matter.”
And in March
They have no money, they have no oil, they have no nothing. They have nice land. They have nice landscape.
And Marco Rubio, in June:
For decades, the regime has stolen and hoarded available fuel — using it for the Castros’ private jet, the security services forces used to repress the Cuban people, to keep empty tourist hotels lit up, and to bus people in for fake protests and political stunts
Mostly, of course, they used it to run hospitals and schools and a power grid for people’s homes. But no more. As the AP reported in August:
A 20-minute burst of electricity is a small miracle in Havana nowadays — a miracle that sometimes comes at 3 a.m.
That’s when 72-year-old Leidis Rodríguez frantically cooked beans after the lights switched on this week following hours of uninterrupted blackouts.
“The power has come back on, everyone go!” Rodríguez shouted.
Public transportation and cultural events have come to a standstill. So has tourism, the country’s economic engine, especially as tourism companies have withdrawn, leaving 25,000 hospitality jobs vacant. Flights to the island are regularly canceled and workdays have been shortened to adjust to the new reality of a Cuba without power. Medicine shortages have worsened and food rots in fridges without power.
“If there’s no electricity, there’s no water because it doesn’t get pumped to the tank. When there’s water, there’s no electricity,” Rodríguez lamented.
Anyway, as people in these nations endure horrific lives, and the world edges closer to truly unspeakable catastrophe, the fact that it’s all connected to oil suggests a way out: which is to make oil less important.
And there’s really exactly one way to do that, which everyone with a heart or a mind (or a calculator) is edging toward: replacing it with clean, cheap, far-less-vulnerable power from the sun and wind. That’s what Cuba is doing, installing solar panels faster than anyplace else on earth. It’s what Ukraine is trying to do, with leadership from heroes like Svitlana Romanko and Razom We Stand. (I was unsurprised to see that she’d given up on Trump this week: “Europe must now lead, closing every remaining Russian energy loophole this month, and proving that the democratic world will keep starving Putin's war machine even when the White House will not."). And it’s what all the bystanders to these wars are trying to do, as they move decisively towards clean energy and EVs to cope with the fallout of events they did not initiate.
Since Trump likes plaques, we should give him one as EV salesman of the decade. We will look back on 2026 as the year that it became entirely clear the Internal Combustion Engine was a relic—sales of electric cars are soaring everywhere. Six hundred thousand electrics were sold in Europe in September, up 39 percent from the year before. As Michelle Lewis reports
The UK, France, Spain, Portugal, and Finland all posted their highest monthly EV sales ever. France’s sales climbed 78% year over year to almost 80,000, while Germany’s rose 61% to 117,000.
Look: every EV sold drops the demand for oil. Every heat pump sold cuts the demand for natural gas. Every solar system that goes up on a roof or balcony produces clean energy with no need for hydrocarbons. And all of it not only helps take some pressure off the climate, it helps—really, far more quickly—to rein in the siege of warfare now underway. If we lived on a planet that ran mostly on wind and solar power, war would be less likely. It’s hard to fight over sunshine. I’ve heard often from people over the years, asking if the climate movement and the peace movement could be more united, and it seems to me that this is the key.
The solar panel is the new peace symbol. Pass it on.
Oh, and the picture at the top is the massive steeple of this Community of Christ headquarters set against last night’s setting sun in Independence. Below is what that spiraling steeple looks like from the inside: to me, the interior of a conch shell, stretching far overhead. The architect has managed to bring the living world inside; I’ve rarely been in a more beautiful building. Or a more peaceful one.

In other energy and climate news:
+Daniel Swain, West Coast weather expert, has a new and ominous set of El Niño forecasts for California:
While it’s true that the “tilt in the odds” toward a stormier and wetter California winter during El Niño is decidedly modest during weaker events, this year’s El Niño is far from ordinary. Amid an El Niño that will become the strongest, and also easternmost-centered, event on record (if it isn’t already), this year’s tilt in the odds toward wet and stormy conditions in California will be profoundly unsubtle.
Indeed, the very latest seasonal update from the international multi-model “superensemble” reflects this quite dramatically. Quite frankly, I’ve never seen anything like it before (and I do not say that lightly!). I’ve spent quite a bit of time over the past couple of weeks crunching the numbers and commiserating with other experts in the El Niño space, and here are some key points from my own quantitative and contextual assessment:
The likelihood of a wetter than average winter in California is extremely high by historical standards (odds >90% statewide)
The likelihood of an extremely wet (top 10%/90th percentile) winter are are much greater than usual (~5x background odds)
There is a greatly elevated risk (around ~20x background likelihood) of a record-wet season, and/or individual record-wet months
High confidence wet signal extends farther north along CA coast and inland vs typical El Niño; highest confidence region includes San Francisco Bay Area/Sacramento region and points south
Peak California impacts will be from December through March, and January & February may feature highest likelihood of extreme wet conditions
It’s worth remembering what a record-wet winter for California could mean: the Golden State has seen some truly terrible floods in the past, with the deluge in 1862 killing one percent of the state’s population. Hopefully, good warning and better infrastructure will help this time.
+Genevieve Gunther has a powerful essay in Current Affairs, arguing that we’re not really taking on the climate crisis because too many elites have too much invested in the status quo.
We already have the technological and behavioral solutions we need to live affluent, modern lives without coal, oil, and gas. The core problem is that the phaseout of fossil fuels would catalyze a serious financial and lifestyle shock to the richest among us. But as a trade-off it would also raise people’s real incomes, making the vast majority of us better off. In a decarbonized and electrified net-zero economy—quite aside from avoided costs of worse heat waves, droughts, floods, storms, diseases, and so on—we would be paying much less for electricity, heating, and transportation, currently a huge chunk of people’s monthly bills. Healthcare costs would decline too, simply due to the public-health benefits of reducing air pollution. (We should think of high health-insurance prices as a sort of fossil-fuel subsidy.) And yes, fossil-fuel phaseout would help to mitigate global income inequality (no more private jets and white boats, for one thing).
+While the new permitting reform legislation that I’ve argued against seems for the moment to have the votes required to pass it, more arguments for caution keep emerging. Here’s Erik Schlenker-Goodrich, Executive Director of the Western Environmental Law Center.
There’s a fundamental question regarding the directionality of climate policy: do we cede control to capital and markets or do we nest capital and markets within a framework of strong, modernized federal governance?
BAAJA, the Lee-Capito-Heinrich-Whitehouse industrial fast-tracking deal, is firmly on the side of market dominance. The bill confers a huge set of concessions to developers of all stripes, including new litigation tools, while attempting to defang public-interest organizations, the public in general, and hobble the next President of the United States.
This is precisely what Section 1402 of the bill is all about, which locks in an “all of the above” energy mix, dominated by fossil fuels. It’s touted as a mechanism to counter Trump’s war on renewables—and it may have some marginal benefits over the remainder of his presidency—but I guarantee you that the fossil-fuel industry will weaponize it against the next president, bringing litigation in federal courts with Trump appointees. If a new president says “We’re going to transition from fossil fuels to renewables,” and then executes that statement through executive orders, regulatory actions, and the like, my bet is that fossil fuels or other interests will challenge that as evidence of “disparate treatment” and prima facie evidence, per the bill, of “an intentional course of action undertaken by the Federal Government to create such a pattern.”
Meanwhile, Chris Nelder provides a fine account of how to argue with oil companies, including some fine and fiery language from RI Senator Sheldon Whitehouse:
November could make actually a really big difference. What you have right now is a president who is essentially the tool of the worst elements of the fossil fuel industry and unrepentant about it. And a congress controlled by his party that is completely spineless when it comes to any kind of resistance to him, and even worse, when they look around at the fossil fuel industry, which is their major donor. And, I mean, they’ve been doing the job of the fossil fuel industry for a decade or more now.
So you have this terrible situation in which there’s almost no resistance to the fossil fuel industry’s command over government and its agencies. That changes very fast, if the power shift changes in Washington to a Democrat-controlled House and or a Democrat-controlled Senate. And in that context, there’s a lot to talk about and to put pressure on. One is dealing with the climate driven insurance crisis that we’re seeing, the great climate insurance collapse, a friend of mine calls it.
+My local utility, Vermont Gas, is investing in geothermal power for the first time, highlighting a growing “gas to geo” trend according to Catherine Boudreau:
The utility, which serves about 56,000 customers in the northwestern part of the state, is covering the upfront cost of the new infrastructure that will provide heating and cooling for a new affordable housing project. Dandelion Energy is handling the system design and drilling.
President and CEO Neale Lunderville told Latitude Media that geothermal networks are good business for Vermont Gas because it allows the utility to continue expanding its customer base even as the state shifts away from fossil fuels. In Vermont, most homes still rely on fuel oil and propane for heating, even as the vast majority of the grid is powered by renewables, such as hydropower imported from Canada. The state in 2020 enacted a legally binding target to cut greenhouse gas emissions 80% by 2050 compared to 1990 levels.
“This is an important part of our long-term strategy to diversify our revenue and keep the service we provide affordable for customers,” Lunderville said.
+A fascinating episode of whisteblowing by an anonymous insurance executive, who wrote a compelling manifesto and an accompanying essay for the Guardian
In the face of ever more extreme and unpredictable climate risks, I am coming under pressure to cut my forecasts for the losses that disasters will cause in order to make insurance more affordable – and get my employer more business. In some instances, the questioning of our numbers and models is justified. But too often, it is not being done to produce more accurate models, but to artificially lower prices. If this is happening at my firm, which is struggling to compete with rivals’ prices, it’s happening elsewhere.
In the most basic terms, we are collectively fudging the numbers and taking on more risk than we should for a lower price than the expected loss demands. Sometimes I will forecast losses that would normally be seen as much too risky for us to insure, but we offer the policies anyway. This will eventually lead to a sector built on “competitively priced” contracts that underestimate risk, leaving gaping holes in the safety net that insurance is supposed to provide.
For example, if subsidence – which is made worse by drought – damages a number of homes in your area, insurers may exclude this from your policy, so you won’t be covered if subsidence then hits your house.
When that happens to an entire community, businesses leave, investment dries up and the local economy tanks. Now imagine this happening in multiple towns around the country, at the same time. And subsidence is just one such issue, alongside wildfires, coastal erosion, wind and floods – and that’s just in the UK.
+The weakness of the Intergovernmental Panel on Climate Change has always been government interference—and there are signs that some players are now getting in the way of the basic budget and mission of the scientific process. As the good people at Earth Negotiations Bulletin report
After a week of contentious deliberations and some displays of temper, the Intergovernmental Panel on Climate Change (IPCC) suspended its 65th session without an agreement on either a timeline for the remainder of its Seventh Assessment Cycle or even a budget for the coming year.
The challenging dynamics that have plagued the Panel since the start of the cycle continued in this session, despite many members’ intensive efforts to find paths to consensus on a range of issues.
+Former Washington governor and unparalleled clean energy champ Jay Inslee took to his excellent Substack last week to describe electrifying his nearly century-old home:
Most months, Trudi and I pay less than $20 on our electric bill – compared to $158, the average family’s monthly bill in the US today. We heat and cool our home, cook every meal, heat our water, and charge our car and virtually all of it runs on clean energy.
When we bought this house around 2000, that was far from the case. On a windy day, you could barely keep a candle lit inside. It was heated by an oil furnace, it had almost no insulation, and the single-pane windows might as well have been wide open.
Nothing about getting from there to here required a miracle. It took about 20 years, one project at a time, as we could afford it. And I believe that every American family should be able to make the same journey, without it taking nearly two decades to do so.
+If you’re wondering why the oil companies are so desperate to win their Supreme Court case in Boulder v. Suncor and prevent any litigation of their climate impacts, check out the latest documents unveiled in a Massachusetts court case. As Nicholas Kusnetz reports, they add to the mountain of evidence that these companies knew all about climate change back in the day, and covered it up, costing humanity decades in the most important fight our species has ever faced. For example,
Just weeks before the U.N. vote [to establish the IPCC], Frank Sprow of Exxon’s corporate research department warned his colleagues in an internal memo, “If a worldwide consensus emerges that action is needed to mitigate against Greenhouse gas effects, substantial negative impacts on Exxon could occur.”
Oh, and remember when Exxon was relentlessly advertising its “algae will someday replace oil” greenwashing campaign? Here’s an excerpt from the deposition of a company scientist:
Asked whether a 2018 press release, which said Exxon anticipated “10,000 barrels of algae biofuel per day could be produced by 2025,” was misleading, the scientist said “yes,” adding, “All the clauses in there are patently false.”
The scientist testified that the 10,000-barrel-per-day target was “completely impossible to achieve,” and that he told this to others at the company before the press release was issued.
+A new report from the NeuroClimate Working Group, a consortium of five hundred researchers looking at the effects of the climate crisis on the human brain. It’s not fun reading
Heat exacerbates existing neurological disorders (stroke, migraine, Alzheimer’s disease, epilepsy, multiple sclerosis) and raises hospital admissions for each.7,8 Modeling studies predict a rising burden of Alzheimer’s, other dementias, and Parkinson’s as warming continues.9
The mind moves in step with the mercury. Every 1°C-increase is associated with a 2.2-percent rise in mental-health-related mortality;1 emergency-department visits climb for mood, anxiety, substance-use, and psychotic disorders, as well as for self-harm.7,10 Some psychiatric medications impair thermoregulation.
Prolonged heat erodes attention, executive function, and mental acuity.11,12 Judges issue harsher verdicts;13 workplaces shed productivity;14 impulsivity, aggression, and crime tick upward.15,16
Neuroscientists believe these effects arise because heat weakens the blood-brain barrier, the tightly packed layer of cells that controls molecular flow between the bloodstream and the brain.17 Heat also triggers neuroinflammation, oxidative stress (the build-up of unstable molecules that can damage cells), and mitochondrial dysfunction. Each of these harms is ultimately linked to the progressive loss of nerve cells known as neurodegeneration.18 Neuroimaging ties heat exposure in infancy to reduced myelination and white-matter maturation19 and disrupted functional connectivity in the adult brain.20
+In the rest of the world, financial flows to clean energy are strengthening, and surpassing the money for new fossil fuel development. In the US, not so much, as a new report from Oil Change International and Friends of the Earth documents
The United States is badly out of step with other G20 countries when it comes to ending their public finance for fossil fuels and prioritizing a cleaner, more affordable energy system. Across the G20 and the multilateral development banks (MDB), between 2023 and 2025, for the first time ever, international clean energy finance overtook fossil fuel finance. However, the United States is going against this trend by increasing its international fossil fuel finance in 2025 to over $8 billion from $1.4 billion in 2024, the most of any G20 country. Meanwhile, the United States’ clean energy finance was only $671.5 million in 2025.
+From Elise Blanchard, a not-to-be-missed-though-very-hard-to-read report on how drought in Afghanistan is pressuring families to sell off their very young daughters as brides.
In Badghis, 95% of the population relies on rain-fed agriculture and livestock to live. But droughts, made more frequent and extreme by climate breakdown, have robbed people of their incomes.
As a result, selling young daughters into marriage to repay debts, feed the family or pay for medical treatment has become a common way to cope.
“As a mother, I cried a lot, but I knew my husband had no choice,” says Gul Bobo, who does not know her own age, regarding her daughters, aged two and five, at her home in Tayz Nāwah, a village 12 hours’ drive from Qala-e-Naw. Both girls are engaged to be married.
Like many there, Gul Bobo’s husband used to buy seeds each year and rent a tractor or donkey to cultivate a wealthier man’s plot of land.
“I know they are too young to be engaged but we had no choice – otherwise we would have waited until after 18,” says Gul Bobo.
“I expect them to be beaten, but there is nothing I can do about it. And at 14, they will be pregnant.”
+Hey! Australia becomes the first nation to officially endorse the Global Solar Council’s drive for 300 million solar rooftops globally
Around 150 million homes worldwide have rooftop solar today, and the initiative aims to double that by 2030.
Sonia Dunlop, CEO of the Global Solar Council, said: “Families everywhere want to bring down their energy bills, and rooftop solar and storage lets them do just that. It took the world around 30 years to reach the first 150 million solar homes. We want to add the next 150 million in just four years. Australia's support and practical experience in implementation is exactly what we need to realise that ambition in every corner of the world."
It’s no wonder Australia is backing this effort, because it has more solar rooftops per capita than any place on the planet. As Graham Readfearn reported last week,
Zoom in on satellite pictures of the Melbourne postcode 3029 and one feature becomes glaringly obvious – there are lots and lots of solar panels on lots and lots of roofs.
“If you walk along the streets, it’s actually hard to see a house without solar panels,” says Saajidh Nizam, a software engineer who lives in Tarneit with his wife, two children and a 6.6kWh solar system on the roof.
In fact, let me leave you with the image of that neighborhood that the Guardian constructed from Google Earth.

I am grateful to all who have been financially able to take out a modestly priced and voluntary subscription to this newsletter, because that’s what keeps it coming!
This is a wonderful post. So many congratulations on the very-well-deserved award.
Dear Bill,
I wish we had spent some real time together when we met in Tallberg in 2008. I would have talked to you about what my mentor, Russell Ackoff (from Wharton… known as the Dean of America's Systems Thinking Community) had taught me about root causes. Were Russ alive today, he'd probably say "Using oil is a symptom… not the cause … of the global crisis we are in, which is a crisis of understanding of the human condition… one in which the wealthy seek to dominate the rest of us and, parallel to that, men seek to dominate women and white men seek to dominate all other cultures."
In other words, we are in a spiritual / emotional maturity crisis… one which will NOT be solved by people learning that "we can replace oil with other means of producing energy". Learning anything new about the history and future of energy needs / production in our world WILL DO NOTHING to change the desire in the (very cold) hearts of the world's most powerful people to rule the world.
Sorry.
What we really need to do is address the "cold heart" crisis in our world… the failure of people like Musk, Thiel, Putin, Trump, et al to care about anyone other than themselves and those cold hearted people just like them.
We need a SPIRITUAL TRANSFORMATION not a breakthrough in the knowledge of what's possible when it comes to producing the energy we need.

The Australia rooftop solar market size reached USD 1,528.1 Million in 2025. The market is projected to reach USD 2,654.1 Million by 2034, exhibiting a growth rate (CAGR) of 6.14% during 2026-2034. The market is propelled by strong policy support and the growing need for decentralized energy solutions. Government incentives and regulatory are making rooftop systems more affordable and attractive, encouraging long-term adoption. Additionally, grid limitations and rising energy demands are encouraging investment in advanced technologies that integrate rooftop solar into broader energy systems. Together, these factors are contributing to a steady rise in the Australia rooftop solar market share. 
Grid Constraints and Decentralized Energy Needs
With energy needs increasing in cities and grid reliability remains uneven in remote communities, rooftop solar provides a decentralized alternative to alleviate strain on the main network. Creating energy at the location of utilization minimizes transmission losses and alleviates peak load strain. To handle this transition successfully, utilities are putting money into cutting-edge grid technologies that enable real-time interaction between distributed energy sources and the primary grid. An important instance is the 2024 collaboration between Itron and Jemena, which launched a Low Voltage Distributed Energy Resource Management System (LV DERMS) in Australia. This system offered real-time information and remote-control features to align rooftop solar contributions with grid requirements, guaranteeing stability and efficiency. Such initiatives indicate a wider trend among energy suppliers to view rooftop solar not merely as a user product but as an essential part of grid infrastructure. These solutions are essential for managing power quality variations and preventing voltage spikes associated with increased solar integration. With the ongoing rise in decentralized solar use, systems such as LV DERMS are becoming crucial for incorporating distributed generation while maintaining reliability, emphasizing the role of rooftop solar in enhancing both household finances and national energy security.

Policy Backing and State-Level Incentives
The Australia rooftop solar market growth is tied to steady policy commitments at both federal and state levels, which is making solar systems financially viable and widely accessible. Programs like the small-scale renewable energy scheme (SRES), along with state-specific rebates, net metering rules, and favorable feed-in tariffs, have collectively shortened payback periods and enhanced return on investment for individuals. These measures not only incentivize system installation but also promote long-term engagement in distributed energy generation and trading. Importantly, government targets and clear renewable energy timelines provide a sense of stability that boosts user and installer confidence. For instance, in 2024, the state of Victoria launched a roadmap aiming to install 7.6 GW of solar by 2035, including 6.3 GW rooftop, 1.2 GW distributed, and 3 GW utility-scale solar. This program directly aided the state's wider objective of 95% renewable energy by 2035 and a net-zero aim for 2045, further aligning rooftop usage with climate responsibilities. By intentionally integrating rooftop capacity into its strategic planning, Victoria strengthened the importance of residential and small-scale commercial solar in reaching statewide decarbonization goals. These specific policies illustrate that rooftop solar is now considered not just an additional energy resource but a fundamental component of Australia's transition approach. These organized and future-oriented incentives maintain ongoing market momentum, particularly as other subsidies start to decline, and establish rooftop solar as a lasting solution integrated into national and subnational climate strategies.
High Residential Adoption
Australia has become a world leader in rooftop solar adoption at the domestic level. A large proportion of suburban and regional homes now boast solar panels, a testament to strong consumer demand to reduce electricity bills and be less dependent on the grid. The high take-up is driven by plenty of sunlight, increasing power prices, and favorable policies. Solar power systems are no longer a rare sight on rooftops, neither in large cities nor in small towns. From a trend of early adopters to mainstream homeowners, the installations have become a routine part of home upgrades or home renovations. The long-term energy savings, coupled with increasing environmental concern, continue to fuel installations. As installation procedures grow more efficient and solar systems more powerful, homeowner demand is far from abating. According to Australia rooftop solar market analysis, residential uptake is expected to remain strong, with continued growth supported by cost reductions, improved technology, and expanding consumer awareness of the financial and environmental benefits.
Rising Electricity Prices
Electricity prices have steadily increased across Australia, placing a growing financial burden on households and small businesses. In response, many are choosing rooftop solar systems as a long-term cost-control measure. Solar power allows users to generate a portion of their energy needs on-site, reducing their dependence on the grid and lowering electricity bills. Time-of-use tariffs and rising peak charges have further incentivized self-generation. For many consumers, the savings from solar outweigh the upfront investment within a few years. This economic motivation continues to be one of the most powerful drivers of solar adoption, especially as inflation and global energy market volatility push power prices higher. The ability to cut ongoing expenses makes rooftop solar a practical choice for energy-conscious property owners.
Environmental Awareness
Public concern over climate change and environmental sustainability is pushing more Australians toward clean energy solutions. Rooftop solar is viewed as a simple, visible way to reduce household or business carbon emissions. As awareness grows about the environmental impact of fossil fuel-based electricity, many consumers are choosing solar to align their energy use with their values. The visibility of solar panels also promotes social proof within communities, further encouraging adoption. Schools, local councils, and community groups are also playing a role in promoting solar as part of broader climate goals. With increased media coverage and education around energy sustainability, solar adoption has become part of a wider cultural shift toward responsible consumption and environmental accountability. This growing environmental consciousness continues to drive consistent Australia rooftop solar market demand, as more households and institutions adopt solar as a practical step toward long-term sustainability.
Technological Advancements
Ongoing technology improvements have resulted in rooftop systems that are more efficient, longer-lasting, and easier to use. Solar panels today produce more energy per square meter, using less roof space to achieve the same output. Smart inverters allow for greater monitoring of energy, remote diagnostics, and connection with battery storage. Most systems today include mobile apps, enabling users to monitor generation and use in real time. Battery technology, although still in development, has improved to be more reliable and cost-effective, leading people to charge power generated during the day for use during the night or for grid outages. Such improvements enhance the solar selling proposition and enhance the overall return on investment. As technology advances, roof-top systems become more mainstream and scalable to more properties.

Homeowner's new mini-split never worked, then he found bad wiring, a leak, and no refrigerant – The Cool Down

© 2025 THE COOL DOWN COMPANY. All Rights Reserved. Do not sell or share my personal information. Reach us at hello@thecooldown.com.
The breakdown came from the installation, with “about everything” done incorrectly.
Photo Credit: Reddit
A homeowner who expected efficient heating from a new LG mini-split instead got a system that cooled, but did not heat — and an unexpected crash course in HVAC troubleshooting. Only after working through installation problems involving the wiring, line set, flare connections, and refrigerant did the homeowner get the heat pump running.
According to an update posted to Reddit, the homeowner said a “knucklehead contractor” installed the mini-split, and the unit never worked.
The week of research led to several corrections. They explained that they swapped Romex for proper connection wire, replaced the bent line set with an insulated set of the proper length, redid all the flares, and installed a proper condensation drain.
For the vacuuming and refrigerant charge, the homeowner got help from a friend who “does some hvac on the side.” The original poster wrote, “As some suggested, one of the flares was leaking and there was no Freon in the unit, replaced all flares.”
Upgrading heating and cooling can cut utility bills and reduce exposure to rising energy prices, but only if the system is installed correctly.
For homeowners comparing newer, more efficient HVAC systems and heat pumps, Palmetto can explain the options, and its Comfort Plan network can connect them with vetted installers and efficient heating and cooling solutions for their home.
A commenter pointed to skipped testing as the likely issue: “Wow, so if the flare was leaking, it means the installer never did a final pressure test. Crazy!”
The homeowner was not dealing with a worn-out system. By the poster’s account, the breakdown came from the installation, with “about everything” done incorrectly. Rather than scrap the unit, the homeowner treated the project as salvageable.
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?
After making the repairs, the poster described the experience as “a learning opportunity.” Another commenter celebrated that outcome, saying it “wasn’t a total loss on the original equipment.”
Other commenters focused on repairability. One commenter wrote: “That’s why I prefer to buy once, repair whenever necessary, and make that initial investment go as far as possible.”
Heating and cooling systems can be one of the biggest household energy expenses, and a properly working system can mean the difference between dependable comfort and a costly headache.
Before signing off on a mini-split installation, homeowners can ask to see the pressure-test results and vacuum reading. In this case, the homeowner eventually got the system working by switching to the proper connection wire, replacing the bent line set, fixing leaking flares, and getting help with the refrigerant work.
For anyone weighing repair, replacement, or a full upgrade, Palmetto’s Comfort Plan offers $0-down options that can cut heating and cooling costs by up to 50%, plus 12 years of free maintenance. That can make it easier to switch to a more efficient system without a big upfront bill.
Homeowners can also pair solar panels with electric appliances, including efficient HVACs, to drive utility costs even lower. EnergySage makes it easy to compare solar options and find the best solar system and installer for a home and budget, and it can help homeowners save up to $10,000 on solar installations.
After the troubleshooting and rework, the original poster wrote: “Anyways, works well now.”
The homeowner added, “Was definitely a learning experience, and made for a fun weekend.”
This kind of installation headache is not unusual for homeowners weighing heat pump upgrades. The articles here cover failed ACs, replacement questions, and more.
• In California, a homeowner facing total AC failure went searching for honest HVAC advice.
• After an old furnace failed, a homeowner weighed cutting-edge HVAC options without upsells.
• Another homeowner found that an expert energy adviser helped compare installers and cut costs.

Tesla's Virtual Power Plants Are Doing A Lot More Than Generating Electricity – SlashGear

In Tesla’s words, a virtual power plant, or VPP, is, “…a community of electric customers on the local power grid who agree to network their energy resources –- such as home batteries, smart thermostats, EV chargers, and solar systems –- to support the grid in ways similar to a traditional power plant.” So, these electric customers are typically homeowners who have already invested in solar panels from Tesla or another manufacturer, have electricity storage systems like the Tesla Powerwall, and own an electric car to use and store energy provided by their VPP.
The benefits of VPPs include their supply of clean, electric power that can take the place of “peaker” power plants, which use heavily-polluting fossil fuels to generate electricity at times of peak demand. Other advantages of VPPs are their ability to replace the construction of additional electricity grid infrastructure, reducing utilities’ budgets and keeping rates down.
The demand for electricity in the U.S. is estimated to increase by 25% by the end of the decade, along with a potential 78% increase by 2050. VPPs don’t need upgrades to their distribution systems or transmission structures, either, positioning them as another way for utilities to reduce the costs of providing power. It has been projected that VPPs could meet more than 20% of U.S. demand by 2030, which could mean significant savings for a wide variety of ratepayers, as well as a major decarbonization of the energy production system as we know it.
With its solar cells, Powerwall home energy systems, and electric vehicles, Tesla adopted this technology early, bringing VPPs to many areas. As of October 2025, these active or pilot VPP projects can be found in over a dozen U.S states, including Arizona, California, Connecticut, Florida, Massachusetts, New York, North and South Carolina, Texas, Utah, and Puerto Rico. Internationally, Tesla has projects in Australia and the United Kingdom.
The VPPs are controlled by software that regulates its electricity usage and the ways in which it is distributed. During calendar year 2024, Tesla paid its Powerwall owners a total of $9.9 million for providing electricity through the VPP system. Tesla’s California VPP system now covers most of the state, and as of June 2026, there are eight states that have mandated VPP programs or active legislation.
What could be standing in the way of more VPPs feeding power back into the grid is the unwillingness of the regulators and the electric utilities themselves to trust sources of power that are not under their direct control, like utility-owned generation plants are. Most VPP programs are involved in providing relief when the grid is overloaded, instead of acting as additional power supplies at all times. 
Other demands on the grid include AI data centers, extreme weather bringing new levels of cold and heat, the increasing costs of aging fossil fuel plants, and mandates at the state level to decarbonize and reduce emissions. VPPs have the potential to reduce the costs of adding the capacity to supply new customers, keeping rates lower. It’s just a matter of making it happen.

China moves to curb exports of advanced solar manufacturing technology – Green Building Africa

China’s Ministry of Commerce and Ministry of Science and Technology have published a draft revision of the Catalogue of Technologies Prohibited and Restricted from Export. The proposal adds 40 technologies, including 12 related to photovoltaic manufacturing, and is open for public comment until 15 November 2026.
An interim pre-export registration requirement took effect on 16 October, the day the draft was announced. It applies to planned transfers of listed technologies, including deals already underway but not yet completed.
The draft proposes an outright ban on exports of production processes and related equipment manufacturing technology for perovskite silicon tandem solar cells. The ban covers tandem cells produced on wafers of at least 182 mm with conversion efficiencies of 30% or higher. It also covers slot die coating processes for perovskites with coating widths of at least 1.1 metres.
Controls would extend to large area modules. Single junction perovskite modules measuring at least 1 square metre and achieving efficiencies of 18% or higher would fall within the proposed prohibited category, as would perovskite tandem modules of the same size with efficiencies of at least 28%.
Other proposed prohibitions include cold hydrogenation fluidised bed processes for trichlorosilane production with annual single line capacities of at least 250 000 metric tons, and silane based fluidised bed processes with annual capacities of at least 20 000 metric tons. The draft also covers processes for manufacturing silicon wafers no thicker than 70 micrometres, certain edge passivation technologies for thin crystalline silicon cells, and related equipment manufacturing know how.
Technologies proposed for the restricted category could be transferred overseas only with government approval and the necessary licences. These include polysilicon plant engineering technologies for production lines with annual capacities of at least 30 000 metric tons, advanced crystal pulling processes and wafer cutting processes.
The draft also covers high-performance manufacturing processes for tunnel oxide passivated contact, back contact and heterojunction solar cells. These include deposition, passivation, diffusion and metallisation technologies. The heterojunction provisions include certain p type technologies assessed under air mass zero illumination conditions relevant to space applications.
Finished solar cells and modules would not be directly affected by the proposed measures. However, transfers of controlled manufacturing know how through technology licensing, overseas production line installation and commissioning, equipment exports and on-site technical support could be prohibited or require government approval.
Companies must register planned exports of listed technologies, including qualifying key equipment, through the Ministry of Commerce online system before transfer. The requirement covers intellectual property transfers, overseas technology licensing, changes in ownership or control involving foreign entities, and transactions in progress.
China’s Ministry of Commerce said the proposals address national security concerns as photovoltaic technologies increasingly find applications in aerospace, defence and other sensitive sectors. It said technologies below the specified thresholds, as well as finished products made using controlled technologies, fall outside the proposed scope.
The ministry added that the measures do not target any particular country, region or company. If adopted, the controls could reinforce China’s position in advanced photovoltaic manufacturing by limiting overseas access to some of its most sophisticated production technologies.

In Massachusetts, $700 utility bills push homeowner to weigh cashing out Nvidia stock for roof and solar – The Cool Down

“Our Eversource bills are absolutely bonkers.”

Faced with an electric bill nearing $700 a month, one Massachusetts homeowner is weighing whether to cash out $48,000 in Nvidia stock to pay for a roof replacement and solar panels.
Before buying an EV, the homeowner said summer power costs were already running $500 to $600 a month, and their house also uses about $2,000 a year in oil heat.
Posting on Reddit’s r/PersonalFinance forum, the original poster pointed to Massachusetts utility costs as the reason their bills feel so steep. 
OP wrote, “We’re in MA, and our Eversource bills are absolutely bonkers,” adding, “I want to get on solar, but we would need a new roof as well… We don’t have liquid funds to pay outright, so I would probably need to sell some stocks. I have some NVDA from 2024, now worth $48,000 and am wondering about selling that.”

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.
They then asked the subreddit, “this may be a case of spending money to save money, but just wanted to get some other opinions… Are people still able to make money these days selling back to the grid?”
Solar appealed to OP due to a combination of practical reasons. Their roof is over 20 years old, the property gets strong sun exposure on both sides, and they hoped a project could wipe out about $3,000 a year in electricity costs while possibly setting up future savings on oil as well.
Yet, the replies pushed back on the idea that panels automatically erase their utility bill. The top comment read, “Don’t just assume solar -> no power bill.” 
At the same time, another Massachusetts commenter who had already moved to heat pumps and an all-electric home said their setup hit break-even at about five years and may cover close to 100% of use, depending on how much the EV is driven.
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 that can help you save as much as $10k on installation.
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 local options for your needs, and their expert advisers can help you compare quotes and pick a winner.
A few commenters said the key question wasn’t whether solar helps, but how much of a Massachusetts bill it can offset. One former Massachusetts resident said their system “essentially eliminated” more than 90% of their electric bill, while noting that chasing the remaining share often stops making economic sense because of diminishing returns.
Examples from other homeowners showed how broad the price range can be. A South Shore commenter shared quotes of roughly $19,715 for a 6,887-kWh system and about $23,987 for an 8,262-kWh option once roofing and engineering expenses were factored in, then later mentioned a 15,383-kWh quote delivered at $20,568.
Rather than deciding based on the stock sale first, many people urged the homeowner to model the energy side carefully. 
They suggested reviewing net metering and time-of-use policies and considering cheaper demand-cutting steps, such as insulation, windows, or HVAC upgrades, including Massachusetts’ heat pump programs, before committing. As one commenter put it, “Insulation is the big one.”

BEIJING, Oct 18 (Reuters) – China has proposed export controls on 12 technologies used to make solar equipment, citing national security concerns, as part of a broader revision that also covers AI and biotechnology.
The ministry of commerce proposed adding the photovoltaic technologies to China’s export-control list, it said in a statement on Friday, adding that greater oversight is needed because solar technologies are increasingly being used in sensitive areas like aerospace and national defense.
Chinese officials held initial talks with manufacturers about potential curbs on advanced solar-panel manufacturing technologies, Reuters reported in April, a move that could threaten plans by US firms such as Tesla to expand production in the US.
Beijing has also curbed exports of solar-manufacturing technology to India, Reuters has reported. Analysts say China is seeking to preserve its dominance as India tries to build up domestic manufacturing and shake off reliance on China.
Export restrictions aim to “guard against the risks of technologies from running out of control or being improperly disseminated, while safeguarding normal international exchanges and cooperation in science and technology,” the ministry said.
Exporters must now register certain overseas technology transfers until the export-control catalogue is formally updated. Public consultation on the proposal will close on November 15.
China would ban technologies including those used to make some thin wafers, perovskite and tandem solar cells, as well as large-scale fluidized-bed polysilicon production technologies.
Perovskite is an emerging technology that offers the potential of increased conversion efficiency. Tandem cells combine perovskite and silicon layers to capture more of the sunlight spectrum.
Fluidized-bed technology for producing polysilicon — a key building block for solar panels — is less expensive and more energy-efficient than the dominant Siemens process.
China would also restrict, but not prohibit, exports of advanced solar cell manufacturing technologies, including TOPCon, HJT and XBC.

Texas to account for almost half of domestic U.S. silicon module production in 2027 – pv magazine Global

More than 45% of all silicon-based solar module production in the United States during 2027 is forecast to take place within a radius of roughly 100 miles from the centrally located I-45 Industrial Corridor in Texas, dominated by assembly plants in the Greater Dallas and Greater Houston regions.
These findings are taken from the latest updates to Terawatt PV Research’s new Solar Manufacturing USA Quarterly report that forecasts the capex and production of domestic U.S. solar manufacturers out to 2030.
The state’s ascent to the top of the domestic landscape has been driven by a select group of multi-gigawatt manufacturers. Companies such as SEG Solar, Canadian Solar, Waaree Energies, and TOYO Solar have chosen Texas for its efficient deployment of capital. Often by retrofitting existing industrial infrastructure, these manufacturers have significantly minimized the time between site commitment and manufacturing ramp, skipping the lengthy construction timelines associated with massive greenfield projects.
The broader appeal of Texas as a manufacturing powerhouse extends beyond the availability of empty warehouses or the solar sector alone. Texas has aggressively positioned itself as a leading national destination for advanced industries by leveraging pro-business fiscal policies and targeted economic incentives. Consequently, the state has built a highly attractive operational launchpad that is drawing significant aerospace, automotive, and high-tech expansions alongside the solar manufacturing boom.
It is noteworthy that several companies also have major plans for new silicon-based cell factories in Texas from 2027 onward, complemented by an emerging network of raw material suppliers rushing to meet the rapid uptick in regional module assembly. Then, of course, there is Tesla. Quite possibly, by 2030, this highly integrated silicon-based ecosystem could make it increasingly difficult for other states to compete on inward investment packages. More importantly, it will cultivate a specialized, highly skilled factory workforce in Texas on a scale that the U.S. solar industry has never seen before.

A Normal Camera That Can Detect Solar Cell Efficiency – bioengineer.org

A Normal Camera That Can Detect Solar Cell Efficiency
Commercial cameras can be remarkably powerful instruments, producing images with exquisite detail that mimic real life, and in laboratory settings, specially designed cameras can photograph objects in the infrared region of the spectrum, invisible to the naked eye. Now, researchers from the University of Stuttgart, the Research Center Jülich, and the German company Solarzentrum Stuttgart have shown that a camera most people could buy at an electronics store can be transformed, with only minor modifications, into a quantitative scientific instrument capable of measuring the efficiency of solar cells. The work, published in The Journal of Applied Physics by AIP Publishing, challenges the long-standing assumption that this kind of measurement demands expensive, carefully calibrated industrial equipment.
The quantity at the heart of the study is electroluminescent quantum efficiency, a value commonly used to determine how well a solar cell converts light into electricity. When a solar cell is electrically biased, it emits a faint glow in the infrared, and the intensity of that luminescence is directly related to the cell’s voltage. Generally speaking, the higher the luminescent quantum efficiency, the better the solar cell, because a more efficient device radiates more light for a given electrical input. Measuring this value has traditionally required dedicated scientific cameras whose response to light must be precisely characterized, a process that adds significant cost and complexity to quality control in photovoltaics manufacturing and research.
Our approach shows that even a relatively inexpensive consumer camera can provide quantitative results when its physical response is properly modeled and calibrated, said author Jürgen Werner. The key insight of the team is that the camera does not need to be a purpose-built scientific detector as long as the way it responds to incoming photons is fully understood. By constructing a suitable physical camera model, the researchers could convert raw pixel brightness into absolute luminescent quantum efficiency, turning an ordinary photograph into a map of local solar cell quality.
The camera the team selected was already primed for the experiment because it lacked an internal infrared-blocking filter, a component that is normally present in most commercial cameras. Manufacturers install these filters so that consumer photographs look natural to the human eye, but their removal opens a window into the near-infrared, where solar cells emit their electroluminescence. Cameras with this filter removed are also popular for artistic infrared photography and for capturing images of the night sky, which means the hardware required for the measurement is accessible to hobbyists as well as laboratories.
To suppress unwanted visible light, the researchers added a long-pass filter in front of the camera lens. This optical component blocks shorter wavelengths, including the visible background light that would otherwise contaminate the signal, while allowing the longer infrared wavelengths of the electroluminescence to pass through to the sensor. The result is a clean infrared electroluminescence image that can later be analyzed based on brightness, with the pixel values encoding quantitative information about the emitting device rather than merely a pretty picture.
An electroluminescence image contains much more quantitative information than simply showing bright and dark regions, said Werner. With a suitable physical camera model and calibration, it can provide absolute luminescent quantum efficiency and, therefore, information about the local quality of a solar cell or module. This local dimension is particularly important in practical photovoltaics, where defects, cracks, or degraded regions within a single cell or module can drag down overall performance even when the rest of the device is healthy. A calibrated consumer camera can therefore reveal exactly where a solar module is losing efficiency, something that previously required laboratory-grade imaging systems.
The implications for the solar industry could be substantial. Quality assurance in photovoltaics manufacturing relies on electroluminescence imaging to spot defects on production lines, and field inspections of installed modules use the same technique to identify degradation caused by weathering, microcracks, or faulty connections. If the physical model developed by the Stuttgart and Jülich teams proves robust across different consumer cameras, the barrier to performing absolute quantum efficiency measurements could drop dramatically, allowing smaller companies, research groups in developing institutions, and even advanced inspection services to carry out measurements that were once the exclusive domain of well-funded laboratories.
The methodology also carries broader lessons for experimental physics. The study demonstrates that the limiting factor in many optical measurements is not the detector itself but the degree to which its response is understood. A consumer camera sensor, with its Bayer color filter array, its nonlinear response curve, and its manufacturer-specific processing, is a far messier detector than a scientific CCD, yet the researchers showed that all of these quirks can be folded into a physical model. Once calibrated, the messy detector becomes a quantitative one. This modeling philosophy could extend well beyond photovoltaics, wherever faint light emission carries information about the underlying device.
The researchers plan to expand the camera’s capabilities in future work, keeping an emphasis on using commercially available technology. Our next step is to use the calibrated camera to determine quantum efficiencies and open-circuit voltages of further, previously uncharacterized solar cells and modules, said Werner. The same model should also be applicable to photoluminescence measurements and potentially to measurements performed in daylight. Photoluminescence imaging, in which sunlight or a laser excites the solar cell and the emitted light is analyzed, is another cornerstone technique in photovoltaics characterization, and daylight operation would be transformative for field inspections, where modules currently must often be measured in darkness or under controlled conditions.
The article New Camera Model for Absolute Quantum Efficiency Measurements from Electroluminescence of Solar Cells or Modules is authored by Jürgen H. Werner, Georgette Udo, and Liviu Stoicescu, and it appears in The Journal of Applied Physics on Sept. 22, 2026. As solar energy continues its rapid global expansion, the demand for fast, affordable, and accurate efficiency measurements grows with it, and this study suggests that the tools required may already be sitting in camera shops around the world. With a removed infrared filter, a long-pass filter, and a well-built physical model, an ordinary camera becomes a window into the invisible light that reveals exactly how good a solar cell really is.

Fine-Tuned Molecular Design Pushes Organic Solar Cells Toward 19.67% Efficiency and Lasting Stability – Bioengineer.org

Fine-Tuned Molecular Design Pushes Organic Solar Cells Toward 19.67% Efficiency and Lasting Stability
Organic photovoltaic cells have long promised a future of lightweight, flexible, and low-cost solar energy, yet one stubborn obstacle has kept them from widespread commercialization: the trade-off between power conversion efficiency and long-term operational stability. A research team based at the Department of Chemistry of Southern University of Science and Technology (SUSTech) in Shenzhen now reports a molecular design strategy that appears to dissolve much of that trade-off, delivering devices that combine a power conversion efficiency of 19.67 percent with remarkably low energy loss and outstanding durability under both continuous illumination and elevated temperature. The study, published as an open access Research Article in CCS Chemistry, the flagship journal of the Chinese Chemical Society, demonstrates that subtle, deliberate adjustments to molecular fine structure can simultaneously optimize the crystallinity and miscibility of the active materials that determine how well an organic solar cell converts and retains energy.
The central challenge addressed by the team concerns non-fullerene acceptors, or NFAs, the electron-accepting molecules that have driven the recent surge in organic photovoltaic performance. In a bulk heterojunction solar cell, a donor polymer and an acceptor molecule are blended together to form an interpenetrating network through which photogenerated charges must travel. For efficient charge generation and transport, the acceptor molecules need to pack into ordered, crystalline domains with close π-π stacking, the parallel overlap of their conjugated π-electron systems that facilitates electron delocalization. Yet excessive crystallinity can cause the acceptor to separate from the donor polymer, degrading the miscibility of the blend and producing a coarse, unstable morphology. Historically, molecular designs that pushed crystallinity upward tended to sacrifice blend compatibility, and designs that preserved compatibility tended to leave behind disordered packing and large nonradiative energy losses, the fraction of absorbed photon energy dissipated as heat rather than converted into charge.
The SUSTech group, led by corresponding author Professor Feng He, approached this dilemma through what the researchers describe as fine molecular engineering. Rather than redesigning the acceptor scaffold wholesale, the team made selective, targeted modifications to a parent molecule designated 7C-2F, which is built around a 1,4-diazahexane core. From this starting point, three new non-fullerene acceptors were synthesized by independently controlling two structural variables: the length of the side chains attached to the molecular framework and the degree of π-conjugation in the terminal groups, the electron-deficient end units that largely govern the optical and electronic properties of the acceptor. This modular approach allowed the researchers to isolate the effect of each structural change on molecular packing, blend morphology, and device behavior.
The first structural variable, side chain shortening, produced two acceptors named 7C-BO-2F and 7C-eC9-2F. The second variable, extension of the π-conjugation of the terminal groups, produced a third acceptor named 7C-N2F. Although these two strategies act on different parts of the molecule, the study found that both converge on the same set of physical outcomes. Each modification improved molecular crystallinity, meaning the acceptor molecules adopted more ordered solid-state packing, and each shortened the π-π stacking distance, the spacing between adjacent conjugated planes in the crystalline domains. Closer stacking strengthens electronic coupling between molecules, which promotes efficient charge transport. Critically, the enhanced order also suppressed nonradiative energy loss, the dominant remaining channel through which modern organic solar cells squander potential voltage.
The photovoltaic results underscore how consequential these fine structural adjustments proved to be. When the acceptor 7C-eC9-2F was paired with the donor polymer PM6 in a conventional bulk heterojunction device, the system achieved a power conversion efficiency of 19.67 percent, a figure that places it among the highest-performing organic photovoltaic systems reported. Equally significant is the energy loss of only 0.539 electron volts, a remarkably small value for an organic solar cell. Nonradiative losses arise when excited molecular states decay without emitting photons or generating charges, and suppressing them is widely regarded as the principal route to raising the efficiency ceiling of organic photovoltaics. The fact that the same molecular features that tighten crystalline packing also curtail these losses illustrates the internal coherence of the design strategy: efficiency gains and morphological improvements flow from a single, unified structural logic rather than from competing optimizations.
Stability, the perennial weak point of organic solar cells, is where the new acceptors distinguish themselves most decisively. Devices based on 7C-eC9-2F were subjected to two standard accelerated aging tests. Under continuous illumination, the time required for the device efficiency to fall to 80 percent of its initial value, a benchmark denoted T80, reached 2728 hours. When the devices were held at 65 degrees Celsius, a temperature representative of real-world rooftop operating conditions, the T80 value reached 1242 hours. In both tests, the 7C-eC9-2F devices significantly outperformed the control systems included in the study. The researchers attribute this durability to the optimized molecular aggregation states and the clear, well-defined microstructure of the active layer, which maintains its charge-generating and charge-transporting architecture even under sustained thermal and optical stress. In effect, the same crystallinity that boosts efficiency also anchors the morphology against the gradual coarsening that typically degrades organic photovoltaic devices over time.
The improved performance stems from a convergence of factors that the authors identify as the mechanistic foundation of the work. Sophisticated molecular engineering of the acceptors produced optimized aggregation states, improved crystallinity, suppressed nonradiative recombination, and a well-defined microstructure. These properties collectively promote efficient charge generation and transport while ensuring morphological durability. The balance between crystallinity and miscibility, often treated as an unavoidable compromise in acceptor design, is here resolved by structural tailoring so precise that both properties improve together. The side chain and terminal group modifications act on the molecular fine structure in ways that tighten packing within acceptor domains without provoking the macroscopic phase separation that would destroy blend compatibility, a result the researchers link directly to the simultaneous gains in efficiency and stability.
Beyond the bulk heterojunction architecture, the team also evaluated the new acceptors in quasi-planar heterojunction, or Q-PHJ, devices, an alternative fabrication geometry in which the donor and acceptor layers are deposited in a more layered arrangement rather than as a fully intermixed blend. The acceptors delivered excellent photovoltaic performance in this structure as well, demonstrating good fabrication adaptability. This cross-process applicability matters for practical manufacturing, because different deposition and annealing protocols impose different demands on material systems. An acceptor that performs well across multiple device architectures offers device engineers substantially more flexibility than one optimized for a single fabrication route, and the Q-PHJ results suggest that the benefits of the fine structural tailoring are intrinsic to the molecules themselves rather than dependent on any particular processing window.
The research was carried out by a team whose co-first authors are Dr. Mingpeng Li, Dr. Waqar Ali Memon, and postdoctoral fellow Xue Lai, all senior visiting scholars in the Department of Chemistry at SUSTech, with Professor Feng He serving as corresponding author. The work was supported by the National Natural Science Foundation of China and the Shenzhen Natural Science Foundation. The study was published on 11 September 2026 under the title Subtle Structural Tailoring Enables Improved Crystallinity and Miscibility for High-Efficiency, Stable Organic Photovoltaics, and the authors report no conflict of interest. The article is available as diamond open access, with no fees for authors or readers, consistent with the publishing model of CCS Chemistry.
The broader significance of the study lies in the design guidance it offers for the next generation of organic photovoltaic materials. By demonstrating that selective control of side chain length and terminal group conjugation can raise crystallinity, shorten π-π stacking distances, suppress nonradiative energy loss, and preserve blend miscibility all at once, the work provides a practical molecular blueprint for overcoming the efficiency-stability trade-off that has constrained the field. The performance of the PM6:7C-eC9-2F system, with its 19.67 percent efficiency, 0.539 electron volt energy loss, 2728-hour illumination T80, and 1242-hour thermal T80 at 65 degrees Celsius, constitutes a concrete benchmark for what fine molecular engineering can achieve. As organic photovoltaics move from laboratory curiosities toward commercial devices, strategies of this kind, which treat molecular fine structure as the primary lever for both efficiency and intrinsic stability, are likely to shape the material systems that carry the technology into practical deployment.

Solar energy increasingly becoming part of major disaster relief efforts – The Arkansas Democrat-Gazette




ISLAMABAD — Every day, Mohammed Saber places a single rectangular solar panel on the roof of the bamboo-and-tarpaulin shack that he and his family have called home for years, the last stop on their journey after fleeing the Myanmar military’s brutal crackdown on the Rohingya in 2017.
The panel is part of a portable solar kit given to the Rohingya refugee family as humanitarian aid six years ago. It’s been the family’s primary source of electricity, making daily life much easier in the camp for the displaced in Teknaf, Bangladesh.
“We can now charge our phones, cook with light, children can study at night and use fans during the hot season,” said Saber, 35.
From the flood zones of Nepal to refugee camps in Africa, experts say solar energy is increasingly becoming part of disaster relief as technology improves, costs fall and humanitarian organizations recognize that having access to electricity is a fundamental need.
Renewable energy solutions are needed more than ever, they say, as climate change drives and intensifies extreme weather while wars, sanctions and political upheavals keep fossil fuel prices volatile.
When disasters strike and humanitarian needs surge, solar kits can become an invaluable resource, says Sarah Rosenberg-Jansen, a research fellow at the Stockholm Environment Institute, an independent research and policy institute specializing in sustainable development.
These solar kits — all-in-one, compact units that are not reliant on utility companies — are easy to move and recharge, according to Rosenberg-Jansen.
“In emergency situations, solar kits can be deployed immediately,” she said, adding that they are particularly useful in situations with rapidly rising floodwaters, changing front lines in a conflict, or for areas where damaged roads make travel difficult.
In terms of function, the kits can be “anything from solar lanterns to solar home systems, solar torches, solar heating pads, to electric cook stoves that use solar as their energy source,” she said.
Rosenberg-Jansen also pointed out that solar panels are not prone to price shocks like fossil fuels, which can be difficult and costly to transport to a disaster zone.
Only a few decades ago, solar energy was a luxury, she added, but as technology evolved, mindsets and the price tag changed. Now it’s more affordable, thanks to the scaling up of mass manufacturing and technology advancement.
It’s also so much easier to use, said Yuriy Boyechko, CEO of Hope For Ukraine, a nonprofit based in the United States that provides solar kits to families living in war-torn Ukraine.

RDH to install solar panels on rooftops of 400 buildings – Amader Barta

#RHD #Dainikshiksha #Dainik Amader Barta
Rdh to install solar panels on rooftops of 400 buildings
To increase the use of renewable energy in government facilities, an initiative has been launched to install solar power panels on the rooftops of more than 400 buildings belonging to the Roads and Highways Department (RHD).
The solar panels with capacity of 5,144 kilowatts (kW) will be installed in these establishments and other unused spaces under the department in phases from the current fiscal to 2029-30 fiscal year.

Through this initiative, the department aims to reduce electricity costs for government offices, decrease dependence on the national grid, lower carbon emissions, and contribute to achieving the nation's renewable energy targets, RHD Chief Engineer Md. Moniruzzaman confrimed .
RHD officials said solar power systems with a combined capacity of 410 kW have already been installed at different RHD facilities, generating about 25,000 units of electricity per month.
The RHD chief engineer mentioned that for the current fiscal 2026-27, steps have been taken to invite tenders for the installation of solar power systems with a capacity of 284 kW.
Additionally, he said, preparations are underway to install further systems with a capacity of 960 kW, while this initiative will be expanded in phases to increase the use of solar power across public facilities.
According to the RHD's roadmap, the targets for solar power capacity installation are as follows: 1,244 kW in the 2026-27 fiscal year, 1,200 kW in 2027-28, 1,200 kW in 2028-29, and 1,500 kW in the 2029-30 fiscal year. The cumulative target for the four fiscal years is 5,144 kilowatts.
The initiative involves utilising not only the rooftops of different departmental buildings but also unused open spaces for solar power generation. Plans are currently underway to develop projects for establishing megawatt-scale solar power plants in these locations.
Moniruzzaman said installing solar panels on the rooftops of government buildings allows for electricity generation without the need for additional land.
He said if the electricity generated during the day is consumed within the respective offices, the dependence on the national grid will decrease, which will lead to cost savings on electricity and enhance efficiency in energy management.
He further emphasised that the use of solar power is crucial for reducing dependence on fossil fuels and lowering carbon emissions.
Consequently, the RHD has devised a plan to identify and utilise all its facilities that offer potential for solar power generation.
The officials said the department views the installation of solar power systems on government building rooftops not merely as a means to generate electricity, but as a comprehensive initiative aimed at reducing energy costs, maximising the utility of existing infrastructure, and promoting green energy.
Experts consider this RHD initiative to be well-aligned with the nation's broader goals for expanding renewable energy.
Muzaffar Ahmed, Chairman of the Sustainable and Renewable Energy Development Authority (SREDA), said Bangladesh is actively transitioning away from fossil fuels toward clean energy sources, such as solar and wind power.
In particular, increasing the use of solar energy will contribute to achieving the country's 'net-zero' climate goal by 2050, he said. The role of the RHD in this endeavor is truly commendable, he added.
According to policy information released by SREDA, the Renewable Energy Policy 2025 sets targets for renewable energy to account for 20 percent of total electricity generation by 2030 and 30 percent by 2040.
Achieving these goals requires a focus on expanding rooftop solar power, large-scale solar power plants, and other renewable energy sources. In this context, it is significant to utilise the buildings and unused land belonging to large government entities like RHD for solar power generation.
By installing solar panels in phases on the rooftops of the department's various offices, engineering facilities and other buildings, a portion of its required electricity could be generated. This would help meet some of the daytime electricity demand at these offices and reduce the load on the national grid.

However, the success of this initiative will depend on the effective operation and maintenance of the installed solar power systems, the efficient use of the electricity generated, and proper grid integration.
Furthermore, regularly evaluating data – such as the amount of electricity generated at each facility, the portion consumed on-site, and the resulting cost savings will make it easier to assess the project's overall effectiveness.

Can we skip ethical banking if we’ve got solar on our cathedral’s roof? – Christian Climate Action

CCA’s Mark Francis has been pondering if it’s okay for cathedrals to not bank ethically if they have solar panels. He’s run the numbers and the results are in.
The transition to renewable energy is a vital part of the fight against climate change. So it’s always very good news to hear that a cathedral or church is considering having a solar photovoltaic (PV) system installed on its roof. Solar PV generates electricity.
Solar is good!
Installing solar PV typically has a significant impact on the emissions related to the use of energy at a cathedral or a church. The emissions saving may look a little like this for a solar system on a cathedral roof;
We certainly want more renewable energy in the UKs energy mix, and at CCA we applaud the many cathedrals and churches that have installed solar PV or are going through the process of doing so.
Fossil Fuel-Free Banking is very good!
So much good is happening in the Church of England to tackle climate change, but many parts of the church, including cathedrals, are still banking with banks that invest in new fossil fuel energy generation.
CCA has recently launched an ethical banking table which highlights this issue and indicates which Church of England cathedrals still bank with fossil-fuel-funding banks.
This generates an interesting question: What would be the impact of – say – £70,000 invested with Barclays Investment Bank ?
Given that most cathedrals will have far more than £70,000 in the bank, making the right choice around banking can have an even greater impact than the significant impact of installing solar.
Both/and, not either/or
No one cathedral, church, individual or organisation can do everything we need to do to tackle climate change, but excusing ourselves from doing one thing because we’ve done another is a dangerous route to go down. We all need to do as much as we can to reduce emissions if want to avoid the worst impacts of climate change.
If a cathedral can, it should install solar AND move to a bank that doesn’t invest in fossil fuels.

Mega solar power farm in Gansu powers China’s green energy ambitions – 巴士的報

Font Size
China
Dunhuang City in northwest China’s Gansu Province is home to the country’s first 100-megawatt molten-salt tower solar thermal plant, a pioneering mega-project that underpins the city’s status as a green energy hub and sets an example for Chinese clean energy projects.
In the plant’s mirror field, 12,000 heliostats track the sun in concentric-circle arrays, reflecting sunlight onto the top of a 260-meter solar power tower. Each mirror covers more than 100 square meters and stands as far as 1.5 kilometers from the tower, requiring milliradian-level precision in angle adjustment to keep the reflected sunlight on target.
To maintain reflection efficiency, workers clean the mirrors before sunset each day with specialized machines and tailored cleaning methods that adjust with the seasons, avoiding water marks and scratches.
As a solar thermal demonstration project, the station was completed and began operation in 2018. Unlike conventional thermal units, which start and stop less often over the year, its operation is closely tied to local weather, with roughly 150 start-stop cycles annually. That frequent cycling puts valves and other components under metal fatigue.
After years of research, imported components of the station are gradually substituted by up-to-standard domestic products, providing a technical reference for similar projects and serving as a test field for Chinese equipment makers.
With its rich and diverse renewable resources, Gansu Province is powering itself and the whole country with wind, solar, thermal power, and new-type energy storage systems, and Dunhuang achieved full-year citywide green electricity supply in 2025.
Gansu’s green power is also being sent to Hunan and Shandong provinces via ultra-high-voltage lines and will soon reach Zhejiang, helping drive China’s nationwide green energy transition.

China’s first-ever multi-generational space rice research has taken a new step toward humans’ ability to fully grow food in orbit, with the Shenzhou-23 crew completing another round of sample collection, sowing, and storage aboard the Tiangong space station.
The research project aims to study the molecular mechanisms behind rice’s multi-generational genetic stability and environmental adaptability in microgravity. Over the past week, the three astronauts collected a new batch of samples, which will be returned to Earth for scientists to analyze at the phenotypic and molecular levels, helping reveal how long-term microgravity affects rice genetic stability.
China’s space rice research began in 2022, when the Shenzhou-14 crew conducted the world’s first full life-cycle rice cultivation experiment in space. During that mission, six rice seeds were grown aboard Tiangong for 120 days, producing 59 first-generation space-grown seeds that the crew returned to Earth.
On May 24 this year, the Shenzhou-23 spacecraft carried a new batch of rice seeds into orbit. The seeds fall into two groups: ordinary seeds that have never left Earth, and third-generation descendants bred on the ground from the 59 space-grown seeds harvested in 2022. Both are Chinese japonica varieties known for their adaptability and three- to four-month growing cycle.
After more than four months in orbit, the Shenzhou-23 crew has reached the first harvest and begun second-generation cultivation using two propagation methods. The aim is to compare how space-flown and Earth-grown rice adapt to space, and to explore how different propagation methods affect second-generation space rice.
The second-generation space rice is expected to mature during the Shenzhou-24 mission, scheduled for later this year.
While the 2022 experiment covered a full life cycle “from ground seed to space seed,” this year’s research advances to “from ground seed to space seed to space seed” — a repeating cycle that researchers hope could provide important theoretical support for in-situ crop production beyond Earth — the ability to grow food in space without relying on resupply from Earth. Such a capability is considered essential for humanity’s future exploration of deep space.

Gombe community gets 1MW solar power plant after 17 years off national grid – Premium Times Nigeria

Nigeria’s Minister of Power, Joseph Tegbe
The people of Talasse in Balanga Local Government Area of Gombe State have received a major boost in electricity supply with the commissioning of a 1-megawatt (MW) solar mini-grid project expected to benefit about 6,000 households and businesses.
At the commissioning ceremony on Saturday, the Minister of Power, Joseph Tegbe, urged residents to protect the newly installed electricity infrastructure against vandalism, theft and other criminal activities that could threaten its sustainability.
The minister stressed that the facility was provided for the benefit of the community and future generations, warning that its destruction or misuse could undermine the investment and deprive residents of its long-term benefits.
“These assets have been built for you, for your benefit and for the posterity of generations to come. I urge you to protect them. Do not allow vandals or other criminals to destroy what has been provided for our collective good,” he said.
He noted that reliable electricity would help local businesses operate more efficiently, improve livelihoods and create economic opportunities for young people.
Mr Tegbe commended the Rural Electrification Agency (REA), the project developer, the Gombe State Government, traditional rulers, community leaders and other stakeholders for their contributions to the project.
He said the initiative aligned with the federal government’s commitment to expanding electricity access, strengthening energy security and promoting sustainable development through renewable energy solutions.
Follow us on Google News and never miss breaking stories, investigations, and in-depth reporting.
Also speaking Governor Muhammadu Yahaya, described the commissioning as a milestone in his administration’s drive to expand reliable and affordable electricity access to rural communities.
He recalled that construction began on November 6, 2025, noting that the project had been completed in less than a year.
According to him, Talasse had remained without connection to the national grid for more than 17 years, limiting economic activities and forcing residents to rely on expensive alternative energy sources.
He added that the state planned to introduce additional solar mini-grid projects with a combined capacity of 4MW in Akko, Dukku, Funakaye, and Kaltungo local government areas, while ongoing projects in Filiya and Gelengu had reached 90 per cent completion.
He said the broader rural electrification programme was expected to extend improved electricity access to 80 communities across the state.
The governor also disclosed that his administration would complement rural electrification with productive-use equipment, including rice milling machines, electric flour grinders and groundnut oil-processing machines, to promote agro-processing, reduce production costs and create employment opportunities.
He called for proper maintenance and responsible use of the facility, urging residents to protect the investment against theft, vandalism and illegal connections.
Mr Yahaya commended the federal government, the Rural Electrification Agency, the World Bank, technical partners and the Talasse community for their contributions to the project.

China proposes export curbs on 12 key solar manufacturing technologies – Yahoo Finance UK

Something went wrong
Investing.com — China has proposed export restrictions on 12 solar manufacturing technologies, citing national security concerns, in a move that could affect overseas production plans and reinforce Beijing’s dominance in the global photovoltaic industry.
China’s Ministry of Commerce announced the proposal on Friday as part of a broader revision of its technology export-control catalogue, covering artificial intelligence and biotechnology.
The ministry said tighter oversight was necessary because photovoltaic technologies are increasingly used in sensitive sectors, including aerospace and national defence.
Under the proposed measures, China would prohibit exports of certain technologies used to manufacture thin silicon wafers, perovskite and tandem solar cells, alongside large-scale fluidised-bed polysilicon production systems.
Perovskite technology offers the potential for higher solar conversion efficiency, while tandem cells combine materials to capture a broader spectrum of sunlight.
Fluidised-bed polysilicon production is also more energy-efficient and less expensive than the conventional Siemens process.
Beijing would separately restrict, rather than prohibit, exports of advanced solar cell manufacturing technologies, including TOPCon, heterojunction technology (HJT) and XBC.
The proposed controls could complicate overseas manufacturers’ efforts to expand domestic solar production.
Chinese officials previously discussed potential restrictions with manufacturers, raising concerns about expansion plans by U.S. companies, including Tesla (NASDAQ).
China has also tightened access to solar manufacturing technology for India, which is seeking to develop domestic production and reduce reliance on Chinese suppliers.
The proposal reflects Beijing’s efforts to maintain oversight of strategically important technologies while protecting its position in the global solar supply chain.
The commerce ministry said the measures were intended to prevent the uncontrolled spread or misuse of sensitive technologies while preserving legitimate international cooperation.
Exporters must register certain overseas technology transfers pending the formal revision of the export-control catalogue.
Public consultation on the proposal will close on November 15.
If implemented, the restrictions could increase uncertainty for international solar manufacturers seeking access to Chinese production expertise.

Legal approval for plug-in solar kits in the U.K. means households can try solar power without installing a full roof array, with potential bill savings of up to £110 a year.
REAL says the new option could make lower-cost home solar available to more people, but it also tells consumers to verify that any kit they buy complies with the government’s updated safety standards.
As of August 27, plug-in solar is permitted nationwide, according to Renewable Energy Magazine. The group said this first stage covers panel-only products, while systems that include batteries are being left out until more evidence is reviewed.
In bright conditions, a single kit can run a fridge, TV, Wi-Fi router, laptop, phone charger, and Xbox S at the same time, REAL said. The systems are rated at up to 800 watts, which the group said is enough to cover up to 20% of a typical household’s electricity use, without installation charges or reliance on grid electricity.
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.
REAL, which runs the Renewable Energy Consumer Codes (RECC), said the policy change followed independent testing of key electrical components and added that products meeting the rules are compatible with U.K. home wiring.
“Clear information, realistic expectations and strong consumer protections will be essential to building confidence in this new market,” said Catherine Cousins, interim director of consumer codes at REAL.
For renters and flat residents, the policy could matter most because those groups have often had limited access to rooftop solar. Cousins said, “Plug-in solar has the potential to make renewable energy more accessible, particularly for people who may not previously have been able to install rooftop solar, such as those living in flats or rented accommodation.”
Going solar is one of the best ways to save money on home energy. If a full rooftop system is an option, homeowners can try EnergySage to get free solar installation estimates and compare quotes.

The U.K.’s framework is also stricter than Germany’s; balcony solar is already widely used there, and about half a million new devices were plugged in during 2025.
MCS figures put certified solar installations at nearly 150,000 in the first half of 2026, 17% above the prior fastest start to a year in 2025, about one every 74 seconds.
Before buying, consumers should make sure any plug-in system is marketed as fully approved and compliant with government safety standards. REAL also said buyers should confirm that their property is suitable and check whether they need permission from a landlord, freeholder, or building owner, or through planning or listed-building consent, before putting panels on a balcony or other outdoor space.
The group also advises consumers to review product details closely, understand maintenance and warranty terms, keep proof of purchase, and be wary of exaggerated savings promises or pressure to buy quickly. The systems are expected to appear online and in stores, with major retailers such as Currys, B&Q, Screwfix, and Amazon having worked with the government on the rollout.

Adding battery storage to a solar setup is one of the best ways to protect your home during outages, save money on energy, and go off-grid. It can also help homeowners use more of the electricity their panels generate instead of sending it elsewhere. Explore EnergySage for information about home battery storage options, including competitive installation estimates.
“Plug-in solar is a simple, affordable way for households to take control of their energy bills and start saving straight away. From this summer, we’re giving more families the ability power their homes with clean homegrown energy,” said Energy Secretary Miatta Fahnbulleh.
Plug-in solar is part of a larger push to make home solar more affordable and accessible.
• In the U.S., advocates say renter-friendly plug-in solar panels could unlock wider home energy access.
• In Maine, lawmakers advanced a bill to provide American renters new access to plug-in solar systems.
• In Colorado, officials backed removing barriers and red tape for residents unable to go solar.
• In the U.K., record levels of rooftop solar show how quickly national demand is rising.
• In North Lincolnshire, a free solar panel scheme reached a milestone with bill-cutting potential.

UHS celebrates solar array – Chadds Ford Live

Stay informed • Subscribe To Our Newletter
It might have been cloudy, but Unionville High School celebrated its new solar array on Friday with an official ribbon-cutting ceremony. The array — installed by TerraSol Energies — covers roughly 70 percent of the school’s roof surface with almost 900 panels.
According to Director of Facilities James Whitesel, since the system went online on Sept. 9, it has already generated 58 megawatts of power.
“That’s 58,000 kilowatt-hours of electricity generated right here on our roof. That’s enough electricity to fully power any one of our elementary schools this past month. And at today’s electricity rates, that’s also enough power to offset approximately $75,000 in electricity costs,” he said.
“I’m very confident the sun is going to continue coming up every morning and now, thanks to this project, the sunshine is working for Unionville-Chadds Ford School District,” Whitesel added.
Funding for the project came from a $300,000 grant from the Pennsylvania Solar for Schools Grant.
Tim Hoffman, the superintendent of schools, said the project took a lot of work and there were many people to thank, including project partners and the state politicians who helped make it come together by voting for the grant program.
“This wouldn’t have been possible without the support of the solar grants,” Hoffman said.
He added that the project coincided with one of the district’s four core values, that of principled stewardship.
“That means we make the most of the resources that we have, whether that’s financial resources or natural resources; we do what we can do to the best of our ability with what we have. This solar array will help offset rising liquid fuel costs and electricity costs that have had a detrimental impact on school budgets.”
Also on hand for the ceremony were state Sen. Carolyn Comitta, D-19, and state Reps Christina Sappey, D-158, and Craig Williams, R-160.
Comitta said, “Energy and the environment are at the intersection of some of the biggest issues and challenges that we face…Pennsylvania is one of about half the states in the nation where electricity rates have risen faster than inflation. Meanwhile, we continue to lag behind in the deployment of renewables.”
She continued by saying the state ranks 47th in growth when it comes to solar, wind, and geothermal generation, but said forward-thinking schools and districts, such as Unionville-Chadds Ford, are leading the way in overcoming such a deficit.
Sappey likewise said the project is a “massive win for students and facilities. Utility bills are consistently one of the largest operating expenses for our public schools. When the House of Representatives created the Solar for Schools Grant in 2024, our goal was to protect local taxpayers by lowering operating costs for districts. By completing this project, Unionville-Chadds Ford demonstrates how state grants reduce overhead and keep district funds focused on where they matter most, on students.”
The final speaker was Craig Williams, who said, “This really is a big moment. There was a little bit of bad news conveyed today about our current development of energy in Pennsylvania, and it’s absolutely true. But there’s also some good news in the message we bring you today,” he added. “We are still the number one electricity exporter state in the entire country, but we’re not building it fast enough.”
Williams went on to say, “The entry of data centers onto our energy grid means that we are now competing with them, for the moment, for the available power. Until we get that fixed legislatively, that is the pricing reality. So, school districts, like Unionville-Chadds Ford, face a daunting financial position which is they can either add power for their own facilities or lean less on the grid where those power prices are out of control. We need to fix this in Harrisburg and Washington, and I think we will, but in the meantime, one thing you can do is add power for your own facilities, take care of your own needs, and lean less on the power grid.”
Williams was the last of the speakers before the ceremonial ribbon cutting.

Homeowner traces a musty smell to the crawlspace, then commenters urge a structural engineer – The Cool Down

“We had something very similar and our floor collapsed soooo spend the money to fix it.”
Photo Credit: Reddit
Trying to trace a persistent musty odor, a homeowner zeroed in on a sunroom crawlspace, and the image shared online raised another issue.
The replies did not stay limited to smell prevention. Several people on the r/homeowners subreddit said the poster should have a structural engineer take a look.
The original poster wrote on Reddit: “The entire first floor has this earthy, musty smell that even goes upstairs to an extent.”
The photo showed sections of subfloor exposed between insulation boards, with tape starting to peel away. The homeowner said this crawlspace is under the sunroom, while the rest of the home sits over a finished basement, and guessed the area was likely “done in 2003 and left like that.”
The discussion moved in two directions at once, revolving around moisture and structure. Looking at the crawlspace, one commenter asked, “Isn’t there supposed to be a support under the house on that nice big concrete support?”
Not everyone saw the uneven crawlspace floor as a major warning sign. A self-identified home inspector wrote, “Crawlspace floors are not typically leveled, so no concern there.” That same commenter still said the area should have a barrier extending “a foot or two up the sides of the walls and secured with adhesives and foam as well.”

Other commenters were much more alarmed about what could happen if the issue is ignored. One person wrote, “We had something very similar and our floor collapsed soooo spend the money to fix it,” while another said plainly, “You need to call a structural engineer. Stat.”
The homeowner said the smell isn’t confined to the sunroom area. The finished basement smells “very musty, too,” and the earthy odor reaches much of the first floor and even upstairs.
A concrete footer visible in the crawlspace became another point of debate. Commenters repeatedly questioned why it didn’t appear to support anything. One suggested it was “probably just an old deck support from before the sunroom,” while another wondered if the visible material was “just foam board.”
Some commenters connected the odor to a larger moisture problem rather than a single bad-smelling spot. One said that if the smell is strongest in the sunroom, “that’s probably the culprit,” but also advised checking drainage around the house and comparing humidity “before and after rain.”
The next step most people mentioned was having a professional evaluate the structure. Multiple commenters tied that advice to the exposed subfloor, the peeling tape, and the concrete footer beneath the room.
For the odor itself, the clearest recommendations focused on reducing moisture in the crawlspace. One commenter suggested to “start with a vapor barrier and go from there.”
Some suggestions also focused on conditions outside the crawlspace. One commenter recommended making sure drainage is good “all around the house” and tracking humidity changes before and after rain to see whether water intrusion is causing the smell.
In follow-ups to commenters, the original poster said they were open to a range of options, including hiring an engineer to look at it, sealing off the sunroom, using an odor absorber, encapsulating the sunroom, and taking moisture readings.
When homeowners and renters track down strange smells or uncover hidden problems around the home, the culprit is often a surprise.
• In California, a resident found a 500-pound creature squatting beneath the house after hearing noises.
• A renter traced a strange odor to shoddy plumbing for a gas stove that looked unsafe.
• A homeowner found a strange object in the garage when the smell suddenly stood out.
• In a rental backyard, a foul problem with the artificial lawn left the outdoor space reeking.

State Permitting Approves 90% of US Wind and Solar Projects, Study Finds – Bioengineer.org

State Permitting Approves 90% of US Wind and Solar Projects, Study Finds
When a wind turbine or a field of solar panels is proposed in the United States, two bureaucratic hurdles stand between the developer and construction: connecting the project to the transmission grid and obtaining a permit to build it in a specific location. Interconnection queues and their notorious multi-year waits have been studied extensively, but the second hurdle, permitting, has remained largely opaque. Now a team of researchers at Lawrence Berkeley National Laboratory, the University of California Santa Barbara, and the University of Massachusetts Amherst has compiled the first project-level dataset of state-based permitting for wind and solar facilities across 19 states, and their findings upend some common assumptions about how hard it is to get a renewable energy project approved.
The headline result is striking: 90 percent of the projects considered by state permitting authorities during the study period were granted permits, and most received their decisions within roughly a year of entering the process. In other words, at least for projects adjudicated under state authority, permitting is not the wall blocking new clean energy from reaching the grid that anecdotes sometimes suggest. The study, published in Frontiers in Sustainable Energy Policy, documents 460 projects across 19 states, representing nearly half of the 41 states identified as having a state-based authority with jurisdiction over some or all large-scale energy facilities.
That such a dataset exists at all is itself a technical feat. Permitting for energy facilities on private land is particularized to individual states, with no common standard for docket record keeping or public data access. The research team searched and reviewed publicly available special permits and related documents, recording dates and decisions for all proposed large-scale solar and wind facilities with permit application dates after January 1, 2018 for solar and January 1, 2015 for wind, and expanded the wind timeline slightly to boost representation given less recent wind development. The data were organized in a relational PostgreSQL database, a structure the authors deemed necessary because individual projects often carry multiple permit applications, decision stages, and regulatory interactions that a flat table could not capture, and then analyzed using R statistical software.
The study period runs through a data collection cut-off of January 1, 2025, and the authors believe they captured the universe of proposed projects subject to state-level permitting authority in those 19 states. For statistically meaningful comparisons between states, they restricted their analysis to states with at least 20 projects with a known outcome, leaving six states, Kentucky, Mississippi, Maryland, Ohio, Minnesota, and New York, plus a combined set of the remaining states. Approval rates among those states varied from 80 percent in Maryland and Ohio to a perfect 100 percent in Kentucky, with Mississippi close behind at 97 percent.
Timelines told a more differentiated story. The overall average from permit application to a state decision was approximately one year, but a one-way analysis of variance testing whether mean permit days differed among the seven state groups was highly significant, F(6, N − 7) = 19.40, p = 2.01 × 10⁻¹⁹. Tukey post-hoc pairwise comparisons revealed two distinct clusters: New York, Minnesota, Ohio, and Maryland averaged about three months above the overall mean, while Kentucky and Mississippi averaged about five months below it. Notably, the researchers found no significant differences in decision time by application year, technology type, or project capacity, suggesting that where a project is permitted matters more than what or how big it is.
The two fastest states share a governance feature that may explain their speed and their near-universal approval rates. In Kentucky, facilities of 10 megawatts or more are reviewed by the State Board on Electric Generation and Transmission Siting, which must render a decision within 180 days of application completion, and the board cannot modify or waive local setback or decommissioning requirements. In Mississippi, the Public Service Commission grants a certificate of public convenience and necessity, but in most cases the project must first obtain agreement from local government. The authors suggest that in these states, most applicants may only apply after already bringing their projects into compliance with local regulations, which would help explain the very high approval rates.
Other states present more complicated relationships with local authority. Minnesota, Maryland, and New York typically preempt local requirements, and it may be that developers in these states propose projects with greater potential impacts, hoping the state authority will be more likely to grant approval. These states also carry state-level environmental regulations that could challenge certain projects. Ohio tells a different tale: since 2021, the Ohio Power Siting Board is not allowed to approve projects that a county has specifically precluded through zoning, a constraint the authors suggest may explain the 20 percent cancellation rate there. Maryland’s commission, meanwhile, may preempt local zoning authority, a power it has held since 2019.
Breaking the permitting process into stages reveals where the time actually goes. Four key dates structure the analysis: Notice of Intent, when a developer publicly announces plans to submit an application; Application Submission; Application Completion, when the authority deems the application complete and begins review; and Application Decision. Across most states, the longest stage is from completion to decision, indicating that authorities spend more time reviewing complete applications than requesting or waiting on additional information from developers. Oregon and New York stand out for substantially longer submission-to-completion stages, and Oregon also shows a long median timeline from Notice of Intent to submission, with the public typically notified at least a year before an application is filed. The authors suggest this may indicate the process is exceptionally onerous for developers to comply with in those states, and that clearer guidelines or standardization could help, though they caution this deserves further research.
Cancellations, the 10 percent of projects that did not receive permits, came in four flavors. A withdrawal is developer-initiated, removing an application before an official decision, and occurred in 8 of the 19 states. Terminations occur when the authority stops considering a project before issuing a decision. Denials are negative decisions from the authority, and one revocation of a previously approved permit occurred in North Dakota. Withdrawals may reflect developers observing a high likelihood of denial or increased costs during review, and the level of opposition a project will experience is notoriously difficult to predict at the onset. The authors note that many more projects request interconnection than are ever built, with connection request wait times typically exceeding four years and unpredictable, and that understanding the interplay between interconnection and permitting will require project-level matching of these datasets, which was not available for this study.
The findings carry weighty implications for the national debate over permitting reform, which in U.S. energy policy often fixates on federal policy and the National Environmental Policy Act. Yet federal permitting is most relevant to projects on federal lands, and to date less than 3 percent of all operating utility-scale land-based wind, photovoltaic solar, and geothermal facilities are located there. The real action, this study shows, is at the state level, where policies vary considerably and where reforms are reshaping the balance between local control and centralized review. The authors emphasize that their analysis cannot speak to community perception of process, project impacts, or cost, and that future research should measure those dimensions across permitting regime types, clarify what factors drive cancellations and long timelines, and establish whether swift approvals correlate with better or worse social and environmental outcomes. Administrative capacity, including sufficient staff and expertise, likely remains critical to states’ ability to process applications, and whether state processes better align projects with clean energy goals, or simply offer fewer opportunities for public participation, remains one of the most important open questions in sustainable energy policy.

HOA asks new homeowners for easement across property: 'I would not allow it unless they paid me' – The Cool Down

“This is a negotiation and you have the upper hand.”

After buying a home in August, a Washington resident says they learned the homeowners association has no established way to reach a wetland area behind the subdivision — and is now asking for an easement across their lot.
In return, the HOA offered to re-bark the owners’ yard once a year.
According to a Reddit post, the home backs up to a “critical area wetland tract” and wetland buffer that the HOA maintains, including fencing and vegetation. But because the tract is “completely surrounded by houses,” the homeowner said the planners never created an easement that would let the association get in to do that work.
They said two issues worried them most: possible yard damage “with equipment” and whether allowing an easement could make the property more difficult to sell in the future.
Commenters focused on the HOA‘s legal authority. One commenter wrote, “The HOA CCRs give them authority to maintain it not you. If you deny them access. They could take you to court to have their access to the wetlead upheld and an easement will be granted. You will pay the HOA lawyers.”
Some commenters said the problem appeared to trace back to how the subdivision was originally laid out, rather than anything the current owner did. “Almost everywhere part of subdividing the land includes handling access via an easement,” one commenter wrote, and asked whether another route would require “an ‘expensive’ driveway, a bridge or some other change.”

Another theme was whether the HOA had other options and simply chose the easiest one. “Why are they targeting you and your house?” one commenter asked, while also raising the possibility that a nearby home not yet sold or still under contract could potentially be modified before closing to provide access instead.
In this Washington case, however, the dispute runs in the opposite direction: The HOA is seeking a new property right after the sale has already closed. Homeowners facing these kinds of conflicts can learn how to work with HOAs to best navigate tricky or limiting situations.
Before agreeing to anything, commenters said the homeowner should get clearer details on how access would work in practice. 
They also suggested challenging the idea that this particular lot had to carry the easement. Recommended questions included why they chose this house, whether the HOA had approached other neighboring owners, and whether any unsold homes could still be adjusted to provide access instead. 
On compensation, commenters largely treated the proposal as a negotiation over a burden on the property, not a courtesy. One wrote, “An easement is certainly a burden on a property,” and suggested putting a dollar figure on how much less the house would have been worth if that easement had already existed at the time of purchase. 
As the original poster put it: “They’re now coming to me asking if we will agree to an easement on our property to give them access to the wetland in exchange to rebark our yard once a year.” 
“Show me the MONEY! I would not allow it unless they paid me,” one commenter wrote. “This is a negotiation and you have the upper hand.” 
This dispute raises familiar questions about property rights, yard access, and how far an HOA can go. Other homeowners have faced similar battles, as highlighted in these stories.
• After HOA pushback, a homeowner installed a gate to a greenbelt without drawing more scrutiny.
• A homeowner grew frustrated when the HOA backtracked on approval for a lawn-saving retaining wall.
• One family said the HOA demanded removal of a fruit tree after years without complaints.

UK homeowner's $29,000 solar quote sparks a bigger question: 40 panels, or more battery for winter? – The Cool Down

“You may not be able to export all you generate.”

A U.K. homeowner was left with a conundrum after being quoted roughly £22,000 ($29,000) for 40 solar panels, two Sigenergy batteries, and a 12-kilowatt inverter.  
Would using as much roof space as possible make the most sense, or would putting more of the budget into battery storage be better for long-term savings?
In a post on the subreddit r/SolarUK, the homeowner said the property could take 12-13 panels on the southeast-facing roof, another 19 on a similarly oriented garage roof, and 18 more on a northwest-facing rear roof. 
Rather than treating 40 panels as obviously excessive, one commenter wrote, “General rule is you can’t have too many panels, you can have an optimal number and that would depend on your house usage.”

Much of the discussion focused on sizing the system to real consumption rather than simply cutting upfront costs.
In fact, going solar is one of the best ways to save money on home energy. EnergySage can help you get free solar installation estimates and compare quotes to find the system that best fits your needs.
Another user said they use roughly 22 kWh during daytime or peak periods. Describing their own system as “23 panels and 28kwh of battery with a 12 KW inverter system all Sig,” they added, “Sizing the battery to be able to cover all your daytime usage in the winter is more important than more panels according to all the payback calculations I’ve done.”
Roof exposure was another variable. The homeowner said the southeast-facing sections get sun early, and that in summer “all areas of the roof is in sun from around 12pm, with this lasting until early evening,” which could shape how much each part of the roof produces.

Want to go solar but not sure who to trust? EnergySage has your back with free and transparent quotes from fully vetted providers that can help you save as much as $10k on installation.
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 local options for your needs, and their expert advisers can help you compare quotes and pick a winner.
They also said the final design may depend on the local grid operator, noting they were “at the mercy of the DNO report,” meaning the distribution network operator could still restrict what is installed or exported even if the roof has space for more panels.
Some replies highlighted trade-offs that can come with a larger array. One commenter warned, “You may not be able to export all you generate,” and added that export earnings could raise tax questions if design generation exceeds 120% of expected household use.
Overall, commenters urged the homeowner to size the system around actual household demand, especially in the darker months. If winter daytime use is the bigger issue, they suggested batteries may deserve priority over filling every available roof section with panels.
Adding battery storage to a solar setup is one of the best ways to protect your home during outages, save money on energy, and go off-grid. In this case, the homeowner was already considering two Sigenergy batteries, and commenters said storage can matter just as much as panel count. Homeowners can use EnergySage to explore home battery storage options, including competitive installation estimates.

Vikram Solar Bags 187 MW TOPCon Module Supply Order – https://www.mvapulse.com/

⚡ Quick Read
Vikram Solar, a prominent name in the Indian renewable energy manufacturing landscape, has announced the acquisition of a significant 187 MW PV module supply order. This contract, awarded by a leading renewable energy developer, underscores the growing demand for high-efficiency solar components in the Indian market. The modules are destined for deployment across three distinct project sites located in the states of Karnataka and Tamil Nadu, both of which remain key hubs for utility-scale solar development in India.
Under the terms of the agreement, Vikram Solar will provide its advanced n-type TOPCon (Tunnel Oxide Passivated Contact) G12R modules. These units utilize glass-to-glass bifacial technology, a configuration increasingly favored for its durability and superior energy yield in diverse climatic conditions. The modules boast power ratings ranging from 615 Wp to 625 Wp, positioning them among the high-performance offerings currently available to domestic EPC contractors. This order strengthens the existing partnership between Vikram Solar and the unnamed developer, further cementing the manufacturer’s footprint in the southern Indian solar corridor.
For EPC contractors and project developers, this order highlights the aggressive shift toward TOPCon technology. As developers strive to optimize land usage and maximize generation per square meter, the transition to n-type bifacial modules has become a strategic priority. Vikram Solar’s ability to deliver high-wattage G12R modules at scale provides developers with the reliability required to meet stringent commissioning timelines. Furthermore, as a Tier 1 manufacturer recognized by Bloomberg NEF for nine consecutive quarters, Vikram Solar offers the bankability that project financiers demand, reducing the risk profile for large-scale solar installations.
The execution of this 187 MW order will contribute to India’s broader objective of achieving 500 GW of non-fossil fuel capacity. As the domestic manufacturing sector scales up, the availability of high-efficiency modules is expected to stabilize, potentially lowering the Levelized Cost of Energy (LCOE) for future projects. Industry stakeholders should monitor the commissioning timelines of these Karnataka and Tamil Nadu sites to gauge the real-world performance of the G12R TOPCon modules. This development is a positive indicator for the India renewable energy sector, demonstrating sustained investment and technical maturation as the country accelerates its energy transition efforts.

Take Advantage of CR’s Bill Negotiator
Stop overpaying on your monthly expenses.
Solar energy can help you save on your electric bill for years to come, but it’s a big investment. Here’s everything you need to know.
Installing solar panels can lower your electricity bills and provide healthy returns in the future–especially given recent rate hikes for electricity. Plenty of American households have already decided to go solar. Investment in solar panels ramped up mightily after the passage of the Inflation Reduction Act (IRA) in 2022, which offered a generous federal tax credit to homeowners who purchased systems. Approximately 6 million households now have solar panels, according to the Solar Energy Industries Association, a trade group. The organization expects that number to surpass 10 million within the next eight years–despite Congress abruptly ending the tax credit in 2025. 
Now, monthly “subscription” services, such as leases and power purchase agreements (PPAs), may be the more feasible path to getting solar panels. But if you want to own a system, there are still state and local incentives for solar. Plus, you may have other options where you live, like tapping into community solar projects, banding with neighbors to negotiate bids with an installer, and even selling back solar energy credits to your utility. The point is, bringing solar energy into your life may be more doable than you realize and can help keep your electric bills in check for years to come. 
Of course, getting a solar array for your home is still a significant investment, not to mention a major home improvement project requiring a skilled installer. EnergySage, a clean energy marketplace, estimates the cost of installing a typical rooftop system at approximately $31,000. Not every property may be a good candidate for solar, and there are local laws and regulations to navigate. You’ll want to choose an experienced company with a track record of working in your area to guide you through the process. So consider these questions when deciding whether to go solar.
Depending on what you spend on electricity, the answer may be a clear yes. The increasing cost of electricity in the U.S. has outpaced inflation over the last year, and it’s clear that people are struggling with these rising prices. About half of Americans report that higher electricity costs have strained household finances, according to a nationally representative 2026 Consumer Reports survey of 2,003 U.S. adults. The same survey showed that a majority of Americans have made or considered significant trade-offs to pay their electric bills, such as cutting back on other spending, lowering heat or air conditioning to uncomfortable levels, or seeking financial help from family members or organizations. Given the real-life effects of higher electricity prices, it’s understandable that people are looking for ways to cover or offset these costs. 
Going solar, while costly, can significantly reduce your electric bills for decades (or possibly bring them to zero), saving you money over the long term. Solar panels typically function at a high level for 25 to 30 years, so you are playing the long game of managing your electricity costs when buying a system or leasing one.
According to EnergySage, while purchasing a solar array may cost more than $30,000, the average homeowner will save more than $60,000 on electricity over the lifetime of their system (depending on how much energy they use and how large their solar system is). 
You can calculate your average monthly electricity expenses and plug that figure, along with your address, into a solar calculator such as Google Project Sunroof, EnergySage, or SolarReviews. Those tools will combine that information with aerial views of your roof from mapping programs such as Google Earth to estimate how large a PV system your home could handle, how much you could save over, say, 20 years, and your investment’s break-even point: that is, when a purchase would begin to pay off. Homeowners who buy a solar panel system could break even in about 10 years, on average, EnergySage says. 
Savings and break-even estimates for the same property can be wildly different among the calculators, so consider them a starting point in your decision-making. And of course, not all panels are created equal. Consumer Reports tested 10 different panels and found 3 clear winners.
With the end of the residential solar tax credit, which benefited homeowners who purchased a solar system, leasing may now be a more accessible option–and in many cases, a good deal. That’s especially true now, since federal tax credits still exist for solar companies that offer leases and power purchase agreements (PPA). PPAs are another kind of third-party ownership model, similar to a lease, but you pay for the energy you generate rather than a standard monthly fee.
But owning a system still has its benefits. And if you’re in a situation to purchase a solar system outright with cash, you’ll save even more money over the long term. That’s because you’re essentially buying years worth of energy in bulk, so you’ll likely get a lower rate for that energy compared to leasing. 
You can read more about the pros and cons of leasing vs. buying solar, but here is a quick summary of what to consider for each.
When you lease:
When you buy:
Getting back-up battery storage, in locations where it’s permitted, is another option for maximizing the electricity you generate with your solar system. Many companies now offer both batteries and solar as a package, whether you lease a system or purchase one. 
“It’s one of the opening questions we ask when we’re chatting with someone: ‘Are you interested in battery backup as well?’” says Clary Franko, chief operating officer of Sugar Hollow Solar, based in Asheville, North Carolina. “Most people come in at this point saying yes.” 
That’s because being able to store the energy you produce during daytime hours would allow you to use that stored electricity during evening hours of peak demand, when your utility may charge a higher rate. Plus, a backup battery can keep you resilient during power outages.
Franko says her customers experienced firsthand how crucial home energy storage could be when Hurricane Helene devastated Asheville and the surrounding area in 2024. 
“One of the things that came out of that was the people who had solar and battery backup systems at their home or business got to see it really work,” she says. “We heard story after story of households becoming these little hubs of resilience in their neighborhoods, being able to take care of people.” 
These lithium-ion devices are made by companies such as Franklin WH, SolarEdge, and Tesla and connect to your solar array via an inverter.  EnergySage estimates that a backup battery could power your home’s essentials for a full day on a single charge, depending on the electrical load. But when those batteries are connected to solar, they can provide power longer, as long as the sun is shining.
If your roof is old, the answer is no–at least not until you replace it. Many solar panels are warrantied to last 25 years or longer, while most roofs are warrantied for 30 years or less. 
With newer roofs, you’ll still only know for sure if a solar installation is feasible after a solar company rep checks out your roof and surrounding foliage in person. They’ll determine whether there’s too much shade or other obstacles, or whether the roof has problems that don’t make an installation worthwhile. 
“A good installer will help guide the process, catering to their customers’ needs and answering all their questions with honesty,” says Ruby Carbajal, president and CEO of Amicus Solar Cooperative, which includes more than 90 community-based solar businesses around the country, like Sugar Hollow Solar. “They won’t focus on getting the biggest system on a roof, whether it makes sense or not.”
Check, too, with your municipality–and homeowners’ association, if you have one–to find out about any restrictions on the type and placement of solar panel arrays.
As we’ve mentioned, working with an experienced installer is central to having a positive solar experience. Roger Horowitz, vice president of Go Solar programs at Solar United Neighbors, a solar advocacy and policy group, offers these best practices for vetting companies:
Go local. Solar is a local enterprise, given varying permitting requirements and arrangements with utilities. So make sure your installer has the experience to navigate the specifics of your location.
Get at least three bids. Start by looking at companies recommended by neighbors or others in your area who have had good experiences.
Compare the price per watt or kilowatt. That’s the up-front cost divided by the system’s size. The lower the cost per watt (the unit price), the better the system’s value. You can use each company’s estimated cost per watt to compare proposals. 
Avoid door-to-door sales. Horowitz says he has heard of roving teams of solar salespeople looking to expand in certain jurisdictions who don’t yet have an established local business. “First of all, we don’t recommend buying stuff door-to-door,” he says. If anything, “tell them, ‘Hey, give me your proposal. I always want to get three proposals.’”
Read online reviews. Make sure they’re good and plentiful. You’re looking for a contractor with hundreds of good reviews, not just a handful.
Ask about warranties. There should be warranties for the actual product (the panels and the inverter) as well as for the amount of electricity those panels are expected to produce. Both of those warranties are typically offered by the manufacturer. Additionally, the installer may offer a warranty for workmanship. 
Check to see whether the company has signed an ethics pledge. Certain states and even counties have solar associations with ethics pledges that companies can sign. For example, Solar United Neighbors helped create an ethics pledge in Ohio. 
Solar United Neighbors also runs a help desk for questions about solar, whether you’re starting research or need to troubleshoot an issue. 
There are a few different ways that you may be able to save on getting solar systems or benefit from solar energy without leasing or owning your own panels. Here’s how:
Most states have community solar projects, which are essentially another type of solar subscription service but with the panels located at an off-site solar farm within your utility area. You pay a solar provider for a share of solar energy and then receive a credit on your electric bill. This can be an option for people whose homes are not good candidates for solar panels–including condo owners or renters–or for those where paying for an individual solar system just isn’t in the cards. New York State, for example, has more than 1,000 community solar projects and offers a guide on how to choose one. As with solar leases and loans, you’ll want to review contract terms closely.
A solar co-op consists of a group of people, all seeking solar systems for their homes, who band together to negotiate bids from installers. Essentially, you’re purchasing in bulk to get a better deal for each household. 
Solar United Neighbors, for example, has organized bulk purchase groups for about two decades. First, they will begin building a group of solar-curious homeowners–about 50 to 100 households–and gather bids from installers without any strings attached, says Ben Delman, the organization’s editorial director.  
“A committee of the participants reviews the bids, chooses one, and then that installer develops a proposal for each co-op participant,” Delman says. “[Homeowners] decide individually if they want to go solar or not.” 
Delman says that, in addition to the possible financial benefits, grouping together for a solar installation can help navigate solar permitting and installation, which is sometimes a lengthy process.
