We’ve got a bunch of power station deals kicking off this week’s Green Deals, starting with Jackery’s combined Early Prime Father’s Day Sale that is offering a 72-hour flash sale window on three units, including the 5,040Wh Explorer 5000 Plus Portable Power Station with 2x 500W solar panels at a new $3,905 low. We also spotted Anker offering a 48-hour SOLIX flash sale on a larger selection of units, like the F2600 2,560Wh Portable Power Station at an exclusive $854, and there are also Early Prime Day deals on EcoFlow’s RIVER 3 series power stations starting from $189. From there, we spotted Navee’s latest UT5 Ultra X Electric SuperScooter dropping down to $2,100 for the first time, the second-best deal of the last year on Worx’s 20V JawSaw Cordless Electric Chainsaw, and more waiting for you below. Don’t forget about all the hangover deals from last week either, which have been collected together at the bottom of the page in our latest Electrified Weekly roundup edition. Head below for other New Green Deals we’ve found today and, of course, Electrek’s best EV buying and leasing deals. Also, check out the new Electrek Tesla Shop for the best deals on Tesla accessories. Jackery has melded its Early Prime Day deals with Father’s Day promotions, taking up to 65% off power stations and offering up to 7% extra savings (using one of three codes at certain pricing thresholds). Right now, there’s a 72-hour flash sale on three units, with one notable inclusion being the brand’s Explorer 5000 Plus with 2x 500W solar panels down at $3,905.07 shipped, after using the code OFFER7 at checkout. At Amazon, were you to buy the bundled station with a single solar panel and add on a second, you’d be spending $503 more. It’s starting the deal here with a cut from its $5,699 MSRP to $4,199 ($100 under last week’s Early Prime Day pricing) that only gets better with the bonus extra $294 cut from the tag, thanks to the bonus savings. We previously only ever saw this bundle go as low as $3,999 during Black Friday, but the combined $1,794 savings lands things at a new all-time low price. Head below to learn more and browse all the flash deals while they last. Jackery has switched up its bonus savings code lineup during this new phase of its sale event, with orders over $1,500 getting an extra 3% discount using the code OFFER3 at checkout, while orders over $2,300 get an extra 5% discount with the code OFFER5, and orders over $3,400 get an extra 7% savings using the code OFFER7. If you’re looking to go big with your backup power support while also having the brand’s best expandability range, not to mention solar charging capabilities, this Explorer 5000 Plus power station bundle is the right choice. It starts here at a 5,040Wh LiFePO4 capacity that can scale up to 60,000Wh. It provides up to 7,200W of steady power delivery through its 12 output ports (4x AC, 2x USB-C, 2x USB-A, 1x DC, and 3x expansion ports for AC and DC use), which can even double to 14,400W output when you’ve paired two stations together. The bundle gives you 1,000W towards its maximum 4,000W solar input maximum, with additional recharging options from an AC outlet, your vehicle’s auxiliary port, or with home integration via the smart transfer switch. This station is ready to cover both 120V and 240V devices/appliances, including RV and EV batteries – plus, there’s tons of ChargeShield 2.0 protections and an IPX4 water-resistant build. You can shop from the full Jackery Early Prime Father’s Day Sale lineup on the main landing page here, or check out all the other Early Prime Day deals from alternate brands over in our dedicated power stations hub here. Amazon is currently offering the latest Navee UT5 Ultra X Electric SuperScooter down at $2,099.99 shipped, which beats out the direct website’s current pricing, where it’s keeping to its full $2,500 tag. This new ride hit the market in February with a launch deal to $1,955, but has only been discounted as low as $2,200 since then. Now, while the brand’s direct Father’s Day Sale is not providing any savings, you can instead pick it up here with $400 slashed from the tag for the second-lowest price we have tracked. Of course, if you want to save a little more money, there’s also the less-advanced UT5 Max Electric Scooter down at $1,400 right now, beating the direct website by $400. You can learn more about this superscooter down below or by reading through our in-depth hands-on review. Not only is the Navee UT5 Ultra X superscooter a monster of a ride that is inspired by Rolls-Royce supercars, but it’s also got NBA legend Kevin Garnett’s signature attached. I’ve been really enjoying my time riding it, what with the 43 MPH top speed and up to 75 miles of travel on each full three-hour charge of its 60V 22.3Ah battery. That ridiculous speed is produced by the dual 1,200W motors (which each peak at 2,400W), and it even comes with a solid lineup of smart features, including NavFlyLock Bluetooth auto-unlock function alongside Apple Find My tracking, AI-controlled adjustable suspension, slope decline assist, anti-rollback hill parking, and uphill push assist, and more. That’s not all that is providing a great riding experience here, as it comes stocked with mechanical features that include a highly durable carbon fiber steel frame, 12-inch self-healing tubeless tires, hydraulic disc brakes alongside an EABS regenerative brake, a dual hydraulic suspension system, 330-pound payload, a 360-degree lighting system, and more. As I mentioned, you can get my full hands-on experience in the recent review here. Navee also currently has its ongoing Father’s Day Sale event with up to 40% electric scooter savings starting from $180, and includes deals like the 44-mile traveling G5 Max Electric Scooter down at a $650 low. As part of the ongoing Anker SOLIX Early Prime Day Sale event, the brand is offering yet another 48-hour flash sale window for a blitz of extra savings on power stations. One notable inclusion is Anker’s SOLIX F2600 2,560Wh Portable Power Station down at $854.05 shipped, after using our exclusive code 9TO5DEALS5 at checkout.

From pv magazine Spain Researchers from the University of A Coruña (UDC) have found that the Spanish coastline could accommodate between 4.45 GW and 6.48 GW of floating offshore solar capacity, depending on the maritime spatial planning criteria applied. The estimated capacity would be enough to supply between 6.2% and 9% of Spain’s electricity demand recorded in September 2025. The study “Assessment of installable offshore solar power capacity in Spain based on maritime spatial planning,“, published in the Journal of Cleaner Production, is the first systematic evaluation of Spain’s offshore solar potential using the country’s Maritime Spatial Planning Plans (POEM), approved under Spain’s Royal Decree 150/2023. Although offshore photovoltaics remains at an early stage of development, the authors said the technology offers several advantages over land-based solar, including greater space availability, fewer land-use conflicts, and improved performance due to the cooling effect of seawater. The study cites previous research indicating that this cooling effect can increase electricity generation by up to 10.2% compared with equivalent onshore installations. It also notes that some floating PV platforms have demonstrated higher energy yields than conventional systems and payback periods ranging from 2.8 to seven years. The researchers said that, in countries with strong solar resources such as Spain, offshore PV could complement offshore wind development and support hybrid projects capable of improving grid stability. The study’s main contribution is a methodology for estimating the installable capacity of floating offshore solar based on the restrictions and permitted uses defined in Spain’s Maritime Spatial Planning Plans (POEM). Current Spanish maritime planning explicitly considers technologies such as offshore wind and wave energy but does not designate specific areas for offshore photovoltaics. To address this gap, the researchers evaluated two scenarios. The first scenario considers only the high-potential areas identified for offshore wind development. The second expands the analysis to all compatible marine areas after excluding protected zones, shipping routes, fishing grounds, military areas, biosphere reserves, energy infrastructure, and other priority uses. For the calculations, the researchers used the Merganser floating platform developed by Dutch company SolarDuck as a reference, assuming a unit capacity of 0.52 MW. The analysis found that the high-potential offshore wind areas could accommodate up to 6.48 GW of floating solar capacity. When the full set of restrictions defined in the POEM is applied, however, the estimated capacity falls to 4.45 GW. Although the second scenario covers a larger total maritime area, the authors explained that many of these zones are fragmented or located in deeper waters, making the deployment of large floating platforms more difficult. Water depth was found to be a critical factor because it determines the length of mooring systems and the spacing required between platforms. As a result, a larger available area does not necessarily translate into greater installable capacity. The analysis also revealed a highly uneven geographical distribution of Spain’s offshore solar potential. Under the scenario based on priority offshore wind areas, more than 90% of the estimated capacity is concentrated in the Strait of Gibraltar-Alboran Sea and Canary Islands regions. When only the general maritime planning restrictions are applied, however, the Levantine-Balearic and North Atlantic regions account for most of the potential. In this scenario, the Mediterranean area alone could accommodate around 2.54 GW, making it the country’s main development hub for offshore solar. The authors said this contrast demonstrates the methodology’s value both for complementing existing offshore wind planning and for identifying new development opportunities in areas that are not currently considered priorities. The study also argues that offshore solar should not be viewed as a competitor to offshore wind but as a complementary technology. One of its main conclusions is that Spain should explicitly incorporate offshore solar photovoltaics into future revisions of its Maritime Spatial Planning Plans, as the current absence of designated areas creates regulatory uncertainty and may limit the technology’s development.

HVR Solar said the Amroha facility is expected to create more than 500 jobs across engineering, operations and administrative functions once operational.
Solar Power World By Apellix | Every solar asset manager knows the math. Dust, pollen, bird droppings, agricultural residue and salt film can steadily eat into production, and depending on climate and tilt, an uncleaned array can lose a meaningful share of its expected annual yield. The cleaning decision has always been a trade-off: production losses on one side, and the cost and risk of putting crews, water trucks and equipment onto rooftops, carports and ground-mount sites on the other. A new option is changing that calculus: the cleaning drone. A cleaning drone is a heavy-lift unmanned aircraft system (UAS) fitted with a hose-fed spray system capable of everything from low-pressure rinsing and soft washing to pressure washing at several thousand PSI. The pilot stays on the ground. The aircraft delivers water, deionized rinse (if necessary) and cleaning solution from above, covering surfaces that would otherwise require rooftop crews, lifts or scaffolding. The technology earned its reputation cleaning structures people couldn’t safely reach, such as high-rise glass, storage tanks and stadiums. Solar arrays are a natural next application. Safety first. Rooftop commercial solar is exactly the environment EHS managers worry about: height, slope and a surface one shouldn’t walk on. A drone takes the crew off the roof entirely. No harnesses, no anchor points, no lift rentals, no fall exposure. For carport canopies and elevated structures, the advantage is even more pronounced. OSHA reports 37% of construction fatalities are due to fatal falls. A drone reduces that fall risk. Speed and uptime. Because there’s no access equipment to set up, drone cleaning compresses job timelines dramatically. Faster cleaning means shorter O&M site visits, less disruption and quicker recovery of soiling losses. Panel-friendly contact-free cleaning. Drones clean without anyone walking on arrays or dragging equipment across modules, reducing the risk of microcracking and damage claims that come with foot traffic and brush rigs. Hard-to-reach sites become routine. Steep rooftops, arrays bordered by water and tightly packed carport rows are precisely the jobs that price highest with traditional methods, and where drones offer the largest savings. The barrier to entry is manageable: In the United States, all one needs is an FAA Part 107 Remote Pilot Certificate, a purpose-built aircraft, training and commercial insurance. Basically, it’s a business in a box for $75,000. A camera drone with a sprayer bolted on won’t survive this work. The recoil from water exiting a nozzle at thousands of PSI demands an airframe and flight controller engineered for it. When evaluating drone platforms, the criteria that matter most include: Reach. Maximum working height determines which rooftops and structures can be serviced. Airframe weight. Lighter is better: the FAA caps small UAS at 55 lb/25 kg including payload, so a lighter airframe pulls more hose and water higher before hitting the regulatory ceiling. Autonomy. Hands-free cleaning modes matter enormously on solar, where the work is repetitive, row-by-row coverage. Automated cleaning improves consistency across thousands of identical modules and lowers the pilot skill barrier. NDAA compliance and origin. Federal-property and government work requires NDAA-compliant aircraft, and the FCC’s late-2025 move to block new foreign-made drones (with exemptions expiring at the end of 2026) makes American-made platforms the future-proof choice for U.S. operators. Training and support. Ask what’s included, how many operators it covers and whether the manufacturer answers the phone. Here’s how the major cleaning drone platforms compare: Information from Apellix Once a UAS is chosen, solar contractors should take training seriously, set up a drone business with adequate liability insurance and then find customers. Drone cleaning is typically priced per square foot, per job or as a day rate, with premiums for access-constrained sites — panels backing onto water, steep terrain or anything a lift can’t reach. Soiling losses are predictable, recurring and expensive, which makes panel cleaning one of the most defensible line items in any O&M budget. Drone cleaning attacks the cost-side of that equation: faster jobs, no rooftop crews, no foot traffic and access to sites that were previously impractical to clean at all. For solar contractors looking to differentiate, and for asset managers writing next year’s O&M scope, it’s a technology worth a hard look in 2026.

I wonder if a tethered drone would need to be closely regulated. It should also be much cheaper than trying to get enough fly time with heavy/expensive batteries. Maybe not applicable for high-rise buildings, it might be great for residential solar panels which are not very high off the ground. I could see a power cord and even a small hose (3/8″ poly) to supply water. The cleaning drone could be navigated with a ground based joystick controller, and have some automatic features that recognized a solar panel, soaped it, and then blasted it. I’d hire a service to clean my panels yearly if it was affordable — Say $50 + $2/panel .

By now, everyone knows that solar is the fastest, most economical way to get more kilowatts into the terrestrial grid. Used in satellites, solar energy is also an essential element in both commercial and national defense systems, as recently admitted by the self-named Department of War. In particular, the US Air Force has been lending its muscle to the space solar industry, and they have some pretty good arguments on their side. In its new iteration as the Department of War, the agency has muted its once-vigorous support for solar ever since US President Donald Trump swept back into office last year. However, a sign of persistent interest crossed the CleanTechnica radar over the weekend, when researchers in Germany unveiled a germanium-based solar module that set a new world record for solar conversion efficiency. Following some digging through the Intertubes, we find that germanium is in short supply here in the US, and that’s a problem. Germanium is used in high-end solar cells and it also appears in infrared optics, night vision systems, surveillance windows, and weapon sights among other defense applications. In January, DoW addressed the germanium shortfall with an award of $18.1 million to a domestic producer, aimed at pumping up the onshore supply chain. In a press statement announcing the award, DoW took note of multiple defense applications. Solar also made the cut. “Germanium is also essential for solar cells that power military and civilian satellites,” the agency stated. No kidding! The US Air Force totally agrees. As described by USAF, solar represents a next-level logistics improvement over fossil fuels. “Today, expeditionary energy relies on diesel generators, fuel convoys and aerial resupply. These systems increase lift requirements, create detectable signatures and introduce operational risk,” USAF explained last March, in an article explaining its interest in solar energy. The USAF article describes how solar can reduce if not eliminate fuel resupply risks to pilots, crews, and aircraft. The idea is to deploy space-based systems that harvest solar energy in orbit, 24/7 regardless of the weather, and beam it down to receivers on Earth. When first introduced in the early 2000’s, the concept seemed too futuristic for any real shot at reality. However, the technology pieces are in place, the cost of rocket launches has dropped, and private sector stakeholders are closing in on the demonstration phase (see more space-based solar background here). USAF does not intend to be left out of the mix. In May, they issued a contract to the US firm Overview Energy to demonstrate how space-based solar systems could be deployed to power large, remote military operations. Overview is among the stakeholders racing to make space-to-Earth solar technology happen within the next 10 years. The company has been testing its equipment on airborne platforms and expects to send it orbiting around the Earth sometime in 2028. Around 2030, they anticipate megawatt-level delivery to Earth, with plenty more where that comes from. “In the early 2030s, we’ll be capable of delivering more than a gigawatt of 24/7 clean energy anywhere on Earth,” the company has stated. The USAF is among those sorting out the Earth-bound end of things. The article posted in March describes research under way at USAF’s academic branch, Air University, with a focus on fuel resupply in the Indo-Pacific region. The project is titled PERSEUS for Pacific Expeditionary Resilient Solar Energy from Uninterrupted Space. The researchers do not advocate for putting the technology to use any time soon, taking note of further R&D work in addition to cost limitations. However, the project does does describe how space solar could be used in defense applications, once deployed. So far, the researchers have demonstrated a scaled proof of concept model for wireless energy transmission from a satellite to a mobile receiver, based on an analysis from NASA. The mobility element is something that distinguishes the PERSEUS project from other space solar technologies, which rely on static receiving stations. For defense purposes, the ability of the receiver to keep up with force movements is crucial. “It shows that space-based solar power could become a future capability that reduces logistics burdens, supports distributed operations and increases operational tempo for the Air Force and the Joint Force,” USAF concludes. “Space-based solar power offers a way to reduce reliance on vulnerable fuel supply chains. It presents a future where energy can be delivered to distributed forces when and where it is needed,” they emphasize. Here on Earth, the President has tried, and failed, to stop the US solar industry from dominating all other energy sources for new, utility-scale capacity additions to the nation’s grid. Solar manufacturers in the US have also been ramping up operations in anticipation of persistent demand for new utility-scale solar power plants. Manufacturing activity in the space solar field is somewhat more difficult to track, but some recent developments in the field indicate that the demand for solar energy in space is also a force to be reckoned with. On June 4, the US defense supplier York Space Systems announced that it has acquired the space solar startup Solestial. “The acquisition secures a domestic source for critical space solar capability at a moment much of the satellite manufacturing industry remains deeply exposed to Chinese-controlled source materials, delivering a meaningful strategic advantage through a secured, U.S.-sourced supply chain,” York explained. If Solestial rings a bell, it should. The company surfaced on the pages of CleanTechnica back in 2023, when NASA tapped it for an award of $850,000 under a project titled, “Next Generation Silicon Based Solar Arrays for Space Stations and Other Permanent Space Infrastructure,” deploying the company’s ultra-thin, ultra-durable, self-repairing silicon solar cells. The 2023 award followed on the heels of previous development support from NASA and USAF, too. By November of 2024 Solestial was preparing its new solar cells for volume production. Earlier this year the company also announced the purchase of specialized manufacturing equipment from Meyer Burger, a once-promising European solar firm that went bankrupt last year. “The strategic acquisition enables Solestial to completely process its self-healing silicon solar technology from wafer to cell in house, significantly expanding its manufacturing capabilities and supply chain control,” Solestial announced on January 21. “Solestial plans to transition the limited solar cell manufacturing currently conducted in Germany to the United States, resulting in a fully integrated cell to module solar manufacturing operation based in the United States,” the company added. That helps explain why York spotted a ripe opportunity to grow its foothold in the space solar field. As for beaming energy from space to Earth, don’t jump the gun just yet. Solestial has stated that its primary market is in-space applications.

OREM, Utah, June 15, 2026 (GLOBE NEWSWIRE) — Cobalt Power Systems (“Cobalt”), located in Mountain View CA and a wholly owned subsidiary of SunPower Inc. (the “Company”) (Nasdaq: SPWR), in partnership with Wunder Power, today announced the completion of the Waterfront Plaza solar installation, which will deliver ~349,000 kWh of clean electricity annually. This project is a significant commercial milestone for Cobalt as it expands its portfolio of complex commercial solar projects throughout California. View of the Waterfront Plaza from the historic Coit Tower. Located across from Pier 33 on San Francisco’s iconic waterfront, the Waterfront Plaza project highlights Cobalt’s ability to deliver sophisticated commercial solar solutions in dense urban areas where engineering precision, safety, and regulatory compliance are paramount. Cobalt President, John Paul Bergh, said, “As building owners need more sophisticated engineering solutions to reduce operating costs and meet sustainability objectives, projects like Waterfront Plaza demonstrate what is possible – and showcase the technical expertise and execution capabilities that have defined Cobalt Power Systems for more than two decades. Working alongside Wunder Power, we have successfully delivered a highly engineered solution on one of San Francisco’s challenging commercial rooftops.” The Waterfront Plaza 220.9 kW DC solar project utilized 554 high-efficiency solar photovoltaic modules and required extensive coordination and innovative engineering due to its special post-tension concrete roof structure. Installation teams had to deploy custom-engineered anchor points, utilizing multiple attachment methodologies, to safely navigate dense post-tension cable layouts beneath the roof membrane. More than 3,000 ballast blocks were strategically distributed across the roof to meet structural loading requirements and provide seismic stability.
Wunder Chief Operating Officer, Kaylee Mulligan, said, “It’s been a pleasure partnering with the Cobalt team on the Waterfront Plaza project. Their attention to detail and commitment to operational excellence made this a seamless collaboration from start to finish. We’re proud to work with high-quality partners like Cobalt to help commercial real estate owners deploy renewable energy across their portfolios to unlock additional long-term value.” The Waterfront Plaza installation further strengthens the strategic relationship between Cobalt Power Systems and Wunder Power as both organizations continue expanding their partnership across California and the United States. SunPower CEO, T.J. Rodgers, said, “This project gives investors a peek at our engineering future as enhanced by the acquisition of Silicon Valley-based Cobalt. The panels shown below are clearly not mounted on ordinary residential mounts. These footings make the system earthquake resilient, and the mount raises all of the panels above the roof, creating a light pathway to the back of the panels that we will use in the future with our second-generation ‘Monolith II’ panels, which will absorb light through glass on both sides of the panel, providing more power per panel.” Waterfront Plaza solar system.

JARRETTSVILLE, Md. — It’s hard to imagine what nearly 9,000 solar panels would look like on this 72 acres along Rocks Road in Jarrettsville, but a longtime resident, Don Brock, would likely have to look at them every day. “It was always farm. It was never intended for anything else and it’s all zoned agricultural,” said Brock, “So when we found out. We saw the signs posted and we heard rumors about it so we started getting really involved and the more we get involved, the more upset we get.” Another solar farm for Jarrettsville
While the county is giving residents a chance to speak out on the plans, their words may be in vain, since state lawmakers passed the Renewable Energy Certainty Act last year, bypassing local zoning for such projects. “We can only hope that people will try to make some adjustments to be good neighbors. A little set back from yards and things,” said Harford County Executive Bob Cassilly, “but as a practical matter, yes, it’s not a whole lot that we can do under the color of law.” That controversial state legislation would allow solar farms to go in on up to five percent of all of the agricultural land in any given county before local zoning would have to be considered. County leaders testified against the measure in Annapolis to no avail. “Just give us a quota. Tell us how much you want and we’ll find land for that in our county,” Cassilly recalls he told them, “and they wouldn’t do that. They specifically targeted the best farmland.” Now, opponents are left with few options, but to appeal to their enriched neighbors. “Those people that are selling out to the solar—it’s very lucrative,” Brock told us, “That’s my assumption.” “At your expense?” “Oh, absolutely.” Little does Brock know that yet another neighbor, Bruce Huber, is about to sell out to a different solar venture as well who would more than make it worth his while. “A lot of money,” says Huber, “I’m not gonna say dollars and pennies, because I’m in a contract, but it’s a lot of money and people don’t understand that, but there’s reasons people do it and mine is for my wife’s health so that’s what the money is for.” “But when we talk about the money, they’re giving you millions of reasons to think about this?” we asked. “Yes. Yes, sir. Millions of reasons,” he replied.

Counsellors Parents Researcher Alumni Partners IPB University, together with the Korea Energy Agency (KEA) and ENVELOPS Co, Ltd, is preparing to implement an Agri-Photovoltaic-based electric motor charging system. The plan for this collaboration was discussed during a visit by KEA President Choi Jae-Gwan and his delegation to IPB University on Friday (6/12). The project, titled “Establishment of an Agri-Photovoltaic-based Electric Motorcycle Charging System in Indonesia,” is funded by the KEA and the Ministry of Trade, Industry, and Resources of South Korea. This collaboration marks a further step in the development of Agri-Photovoltaic technology at IPB University. In 2025, the Agri-Photovoltaic Research Station was inaugurated at IPB University’s Cikabayan Educational Farm, making it the first of its kind in Indonesia. This facility integrates agriculture and solar energy on a single plot of land to support food productivity while generating clean energy. “This collaboration brings together two key pillars of the future: renewable energy and sustainable agriculture. This partnership serves as a concrete example of how innovation can address food and energy challenges simultaneously,” said Prof Iskandar Z Siregar, Vice Rector for Global Connectivity, Cooperation, and Alumni at IPB University. KEA President Choi Jae-Gwan expressed his satisfaction with the results of the Agri-Photovoltaic project developed in collaboration with IPB University. According to him, the success of this first project demonstrates IPB University’s research and implementation capabilities in developing technology that bridges the agriculture and renewable energy sectors. “Through this project, KEA has been able to witness firsthand IPB’s outstanding research capabilities and proactive commitment to collaboration. We believe this experience serves as a crucial foundation for planning new projects currently under development,” he said. Meanwhile, the Agri-Photovoltaic project manager, who is also a lecturer in the Department of Soil Science and Land Resources at IPB University, Dr. Bambang Hendro Trisasongko, explained that this technology is highly beneficial as it integrates food, energy, water, and natural resources into a single sustainable system. “The current research has entered the third soybean planting cycle. In the first cycle, soybean productivity was approximately 1,6 times higher compared to open fields,” he said. Additionally, he noted that the development of Agri-Photovoltaic has also attracted students and researchers from various countries to conduct research at IPB University.

Fraser Stewart wants every town and village to have its own renewable power source – such as wind turbines or solar farms – and it is his job to turn this idea into a reality. Stewart is head of local energy strategy for GB Energy, the company set up by the UK government to develop green energy projects. The publicly-owned company, which is headquartered in Aberdeen, has been criticised for confusion over what it will actually do and whether its role has been watered down since it was first announced. But Stewart is clear that his personal task is to deliver 1,000 community-owned renewable projects across the UK by 2030. He hopes these will both provide power and generate a steady income for the towns and villages involved. Wind turbines and solar panels are not popular with everyone, especially when they are confronted with the visual impact or disturbance, but Stewart insists they are vital part of Scotland's transition to a clean energy future. He told BBC Scotland's Scotcast podcast that he's been talking about community ownership of energy for the best part of 10 years, long before he got his current job. "The idea is that rather than relying on big energy companies to come in and build the wind farms and the solar farms, communities can do it themselves," he says. Stewart admits these will necessarily be on a smaller scale and that big energy firms will still be needed for large-scale projects – but he says any town or village can get involved, provided they have good support. "It is tricky to do," he says. "It takes an awful lot of will and collective enthusiasm to get it done but when those assets start generating and they sell their electricity, the profits then get reinvested back into that community." In the podcast, Stewart cites Huntly in Aberdeenshire, which has a population of 4,600, as an example of a town that has already taken up the community-owned turbine idea. It owns a wind turbine, which sits alongside others which are commercially-owned on a hill above the town. Donald Boyd, joint general manager of the Huntly Development Trust, said it had been "a long and drawn-out process" – but that he feels "very fortunate" that the project went ahead. The idea began in 2010 but took six years before the community trust received its final boost of funding. The overall cost for installation, purchasing, planning/consultation fees and to gain connection to the electricity grid was £1.5m. Boyd says issues such as getting energy back into the grid are "humongously difficult and expensive" in Scotland. The turbine generates a maximum of 500kW of electricity, which Boyd says is small compared to commercial projects. It is paid for its electricity at a rate guaranteed by a pre-2019 feed-in tariff, which was put in place to encourage people to invest in green energy but has since been replaced. Over the course of 10 years, it has brought £1.5m for investment into the local area after all operating expenses, loan repayments and maintenance. As a result, Huntly town centre now boasts a refurbished cinema and co-working space as well as a banking hub from the generated income. Fraser Stewart, who is originally from Forfar, says he wants to see projects like this across the UK. He is building on the existing schemes such as the Scottish government's Cares programme, which has been backing community energy for a number of years. "There is more money in the local and community energy sector now than there ever has been in Scottish or UK history," he says. "I would say to anyone who thinks this is a good idea 'now is the time, there is a gold rush on this stuff'. "The good news is that where there has been difficulty in funding it in the past – where communities have relied on individuals championing it and driving it through despite the funding landscape – actually now there is real political momentum behind it and real will." Stewart says these projects will not necessarily be how the transition to renewable energy is powered, but that they can play a big part. "It can be one turbine in Huntly or Orkney Council setting up really big wind farms that then power bits of the island and generate money for the community," he says. It can also be small projects such as putting solar panels on school rooves, like he did when he worked as a community organiser in Glasgow. "That was a fairly meagre amount of community benefit, the profits that get generated back, but all of it goes into the local community," he says. "I think there has been a misnomer in the past that it is just for the leafy middle classes or you can only do it if you are out in a village somewhere and you have no other choice. "Every type of community across the country is doing this stuff now." GB Energy has not been without its share of criticism in the year since its inception. Earlier this month, the firm was labelled "an ideological election promise" by Conservative Gordon and Buchan MP Harriet Cross. Cross, who is also a member of the Scottish Affairs Committee, says GB Energy is one of the "largest white elephants we've seen in years". Her comments came after it was revealed the publicly-owned company has just 30 permanent employees. Cross said: "Labour promised GB Energy would create 1,000 direct jobs, but with just 30 permanent employees, it's little wonder that people across the north east feel like they've been sold a dud." But Stewart told Scotcast: "The reality is GB Energy is a year old. "So, it's a case of getting everything in place that you need to deliver investment in big energy projects. "We're now at the point where we are ramping up that direct recruitment in Aberdeen." He added: "In the next couple of years we will be employing 300 permanent staff, mostly based out of Aberdeen, which is part of the promise. "But the bigger numbers around the jobs are attached to the investments we make in renewable projects." Thousands of fans watched the Red Sox play against the Texas Rangers Hundreds of workers have accepted offers from bosses at Glasgow and Edinburgh airports. Watch as thousands of Scotland fans sing Runrig's 'Loch Lomond' at their opening World Cup match against Haiti in Boston.

JARRESTTSVILLE, Md. — As neighbors in Abingdon held a community meeting, people in Jarrettsville are voicing concerns over a proposed solar farm. Jarrettsville residents push back on proposed solar farm off Rocks Road
On Wednesday, neighbors gathered to discuss the plans for a property off Rocks Road. It calls for nearly nine thousand solar panels on 72 acres. It’s the second proposed solar farm in Jarrettsville. RELATED:Another solar farm for Jarrettsville

With less than a month left before the key, July 4th Federal Clean Energy tax-credit deadline, a federal judge has handed the solar industry an unexpected win, restoring the 5% safe harbor that Trump’s IRS tried to kill. Last week, a US District Court for the District of Columbia vacated IRS Notice 2025-42, which had sought to eliminate the previous 5% “safe harbor” rule established in 2018, which defined the beginning of construction (BOC) date that could allow solar panel system projects with longer lead times to qualify for valuable Section 45Y and 48E tax credits. If you missed it, here’s what the 2018 notice actually says: SECTION 3. METHODS FOR ESTABLISHING BEGINNING OF CONSTRUCTION .01 In general. This notice provides two methods for a taxpayer to establish that construction of energy property has begun for purposes of the ITC under § 48. A taxpayer may establish the beginning of construction by starting physical work of a significant nature as set forth in section 4 of this notice (Physical Work Test). Alternatively, a taxpayer may establish the beginning of construction by meeting a safe harbor based on having paid or incurred five percent or more of the total cost of the energy property as set forth in section 5 of this notice (Five Percent Safe Harbor). Both methods require that a taxpayer make continuous progress towards completion once construction has begun (Continuity Requirement). Section 6 of this notice discusses the Continuity Requirement and provides a safe harbor for satisfying this requirement (Continuity Safe Harbor). IRS N-18-59 The Trump administration had been moving to eliminate the safe harbor path for most solar and wind projects last year, forcing developers to rely on a far more demanding “Physical Work Test” standard to establish BOC instead, but Oregon Environmental Council v. Internal Revenue Service (Civil Action No. 25-4400 (CKK)) has effectively put that effort to bed. “This is a significant victory for the industry as it provides an extra layer of certainty for those who want to claim the credit,” writes Bill Curtis, an attorney at Spencer Fane. “The IRS typically cannot unilaterally increase a taxpayer’s tax burden absent congressional action. Notice 2025-42 was clearly an attempt by the IRS to dissuade taxpayers from claiming a rightful deduction. Courts, not IRS notices, are the ultimate arbiters of tax deductions. The District Court’s opinion is well-reasoned and provides ample certainty to anyone who meets the 5% rule, even if the IRS appeals or attempts to limit the deduction in the future.” In other words: if your installer told you that your project wouldn’t qualify for safe harbor, you might want to give them a call, because IRS N-2025-42 might no longer apply. Tax law is a messy, complicated, and high-stakes field. Federal tax credits, state laws, utility programs, and the fine print in the contracts from company to company can overlap or even contradict each other, and navigating any part of it isn’t especially intuitive. That complexity is exactly why the smart people you know hire accountants and tax professionals to make incentives work for them, and you should do the same. If you’re considering a lease or PPA, a conversation with a qualified professional installer can help you understand what’s being offered and how a given deal is being structured. Take that information to your accountant to understand what’s real, what’s marketing, and what actually saves you money. Finally, if there’s money on the table, make sure you don’t leave it there! Remember that US tax law could be a single line codified into law. Instead, it’s more than 4,000+ pages of densely worded legalese.

15/June/2026 In a major step toward building a more climate-resilient tourism model, the Bad Kleinkirchheim mountain lifts (Bad Kleinkirchheimer Bergbahnen) have officially secured a €60,000 state funding package to supercharge their transition to solar energy. Carinthia’s Provincial Councillor for Energy and Economic Affairs, Sebastian Schuschnig, traveled to the resort to personally present the financial commitment to Hansjörg Pflauder, the managing director of the Bad Kleinkirchheim mountain lifts. The state-backed subsidy, pulled from Carinthia’s specialized energy department, will offset the capital expenditures of a newly completed, multi-site photovoltaic network engineered to run heavy ski resort infrastructure entirely on green energy. Powering the Mountain from Roofs and Facades The newly integrated green energy matrix spans four strategic buildings across the mountain and ski area. Rather than clearing forested land for ground-mounted solar arrays, engineers utilized existing real estate by plastering solar panels across highly exposed roof and vertical facade surfaces.
The four interconnected systems generate a combined peak output of 306.38 kWp. Because of the high-altitude setting, the panels benefit from increased solar radiation and the natural cooling effect of mountain air, which prevents overheating and maximizes conversion efficiency compared to low-elevation urban arrays. A Direct Pipeline to Snow Cannons and Lifts Unlike traditional residential solar setups that feed electricity back into a public utility grid, Bad Kleinkirchheim’s network is designed for immediate, on-site consumption. The clean electricity flows directly into the daily operations of the mountain railways. The generated power is wired to run the resort’s primary energy hogs: the high-voltage cable car systems, chairlifts, and the expansive automated snowmaking network. On freezing autumn and winter mornings, the solar array will directly feed electricity into the mountain’s high-pressure pumping stations, water storage reservoirs, and automated snow cannons, allowing the tourism company to offset a massive chunk of its seasonal carbon footprint. Redefining the Energy Transition in Alpine Tourism The initiative comes as ski areas across Europe face intense scrutiny over their energy consumption amid warming winters and volatile electricity markets. State officials are holding up Bad Kleinkirchheim as a prime blueprint for how the outdoor recreation sector can achieve self-sufficiency. “The Bad Kleinkirchheim mountain lifts demonstrate how the energy transition can work in tourism,” Provincial Councillor Schuschnig emphasized during the presentation. “The electricity generated on their own roofs flows directly into operations. Every euro of funding also flows back into the local economy multiple times and largely remains in the region.” By shielding itself from fluctuating commercial energy prices through clean, independent generation, the resort is laying a sustainable financial and environmental foundation to safeguard its winter operations for years to come. 01/June/2026 01/June/2026 01/June/2026 02/June/2026 03/June/2026 Snowsports News is a global news platform dedicated to skiing, snowboarding, and the wider snowsports industry.

Advertisement Nature Photonics (2026) Cite this article Thermal instability under temperature fluctuations remains a critical challenge for the practical deployment of perovskite solar cells. Here we report a wide-temperature-range fluid-phase grain boundary (WTR-FGB) strategy enabled by incorporating a molecular complex that remains fluid between −40 °C and 85 °C. When introduced into polycrystalline perovskite films, this molecular complex is found to preferentially localize at grain boundaries, forming a dynamically adaptive and mechanically compliant intergranular network. This WTR-FGB configuration appears to accommodate thermally induced lattice mismatch, mitigate strain accumulation and suppress defect evolution during thermal cycling. Correspondingly, perovskite films exhibit enhanced structural integrity, improved photoluminescence stability and reduced morphological degradation under repeated temperature variations. These material-level changes are associated with improved device performance, enabling n–i–p perovskite solar cells with a certified power conversion efficiency of 26.52%. Thermal cycling durability is also improved, with p–i–n devices retaining over 92% of initial power conversion efficiencies after 200 cycles in accordance with the International Electrotechnical Commission 61215 standard. This work suggests that mechanically adaptive WTR-FGB engineering may offer an effective pathway towards improving the efficiency and thermal robustness of perovskite photovoltaic devices under operational temperature fluctuations.

China’s top coal-producing region plans to build the country’s largest base for turning coal into oil, gas and chemicals to help reduce reliance on imports, highlighting how the Iran war has sharpened China’s focus on energy security. Inner Mongolia is also China’s top producer of renewable energy, making it a microcosm of the country's complicated energy transition, with a reliance on foreign oil sitting alongside a relative abundance of coal. At the same time, the process of converting coal into petroleum products is a significant and growing source of carbon emissions, challenging China's climate goals. "We are scaling up and strengthening the domestic production capacity of coal-to-oil, coal-to-gas and coal-to-chemical projects in order to increase the domestic self-sufficiency of oil and gas," Huang Zhiqiang, the number two official in the region, said at a press conference on Thursday without providing further details. A growing industry found almost nowhere else, production is still small compared to the vast amount of oil and gas China imports. China’s production volume of gas, liquids and chemicals from coal in 2024 was enough to replace only about 6 percent of the gas and crude oil China imported that year. However, production is growing and in May, China's environment ministry signed off on a 22.1 billion yuan (US$3.3 billion), 800,000 metric-tons-per-year coal-to-olefin demonstration project in Ordos, Inner Mongolia. Olefin is a basic building block for plastics and chemicals. Profits for the coal-to-petrochemicals industry have surged since the Iran war as the use of cheap domestic coal puts it at an advantage over petrochemical competitors who rely on more expensive oil as a feedstock. Huang did not directly respond to questions on how policymakers would address the carbon cost of the process, but said Inner Mongolia is balancing utilisation of its massive coal reserves with growing development of renewable energy, which has risen to 53 percent of the region's installed capacity. Government documents show plans to promote green hydrogen in coal-to-chemicals projects, a move that clean energy advocates warn should not be used to justify further expansion of the sector. Inner Mongolia produces around 1.25 billion to 1.28 billion tons of coal every year, Huang said, more than a quarter of China’s total. Two-thirds of that is produced in Ordos, where the government is building the coal-to-petrochemicals base. Reuters 𝗗𝗼𝘄𝗻𝗹𝗼𝗮𝗱 𝗧𝗵𝗲 𝗦𝘁𝗮𝗻𝗱𝗮𝗿𝗱 𝗔𝗽𝗽 ↓
Following a May incident in Gütersloh, Germany, where a firefighter was injured by electric shock during a blaze at a site with photovoltaic roof tiles, another fire broke out at a home fitted with solar tiles on June 9 in Kleve. The fire affected a single-family home and required about 65 firefighters, who worked for nearly five hours to extinguish the fire. Initial reports of a balcony fire escalated after crews arrived and found the roof structure involved. According to Kleve fire department spokesperson Florian Pose, the roof included integrated photovoltaic tiles and a green roof system, which complicated firefighting by making hotspots harder to detect and prolonging operations. The fire remained confined to the roof, and the interior was not affected. All occupants evacuated safely, and no injuries were reported. The cause is still under investigation. During the operation, firefighters partially dismantled the roof to reach hidden hotspots and fully extinguish the fire. The intervention lasted until about 7:00 p.m., after which the fire was out and the road was reopened. One key challenge with integrated photovoltaic roofs is that the modules continue generating voltage when exposed to sunlight. “When the sun is shining, these modules are always energized,” said fire department spokesperson Florian Pose. Unlike standard rooftop systems where panels are mounted above the roof, solar tiles are built into the structure itself. This makes access more difficult and complicates ventilation and firefighting tactics. The Kleve fire came just weeks after a similar incident in Gütersloh, where a firefighter suffered an electric shock while dismantling photovoltaic roof tiles during a roof fire. The firefighter was treated in hospital and did not suffer serious injuries. The Gütersloh case highlighted broader risks linked to building-integrated photovoltaics (BIPV), including persistent electrical generation during daylight, hard-to-access conductors, and the need to remove structural roof elements during firefighting. While European fire services have developed protocols for photovoltaic systems, the growing use of integrated solar solutions is introducing new operational challenges.

EarthTalk Q&A Marium Zahra —Pat Billings, Butte, MT Agriculture requires large amounts of resources, especially water and energy. Almost a third of global greenhouse gases are linked to agriculture. As world population grows, the demand for food and agricultural production only increases. That’s where agrivoltaics come in, utilizing land for both solar installation and agricultural production, fostering a symbiotic bond between agriculture and energy. Agriovoltaics allows for more efficient land use while also protecting agricultural yields. Solar panels protect plants from intense weather conditions and prevent them from exceeding their light saturation point, while plants help keep solar panels cool. The protection of plants also protects economies that rely on agriculture. At the same time, solar energy can power essential agricultural needs like equipment. The excess energy produced in agrivoltaics is stored in battery banks or transmitted to the grid for other users. Agrivoltaics represents the epitome of sustainable agriculture and climate resilience because of its ability to address various concerns. It also provides a renewable energy system that directly limits greenhouse gases by reducing reliance on fossil fuels, thus mitigating the carbon footprint involved in agriculture. Agrivoltaics also promotes water conservation by ensuring that plants are not oversaturated with sunlight. Chad Higgins, an environmental engineer at Oregon State University, told Reuters in 2023 that agrivoltaics nullifies the choice between energy and farm production. “The solar versus ag debate is a non-starter…They’re [solar panels] like any other electronic device, they become more efficient as they become cooler, so it can be a truly symbiotic relationship.” Challenges still exist, especially cost. The high start-up expenses and the difficulty in having farmworkers adapt to new systems are obstacles that reinforce the importance of realism. Still, the many advantages of agrivoltaics are a reason for optimism. According to Colorado State University, utilizing agrivoltaics for land systems can potentially increase farm productivity from 35 to 73 percent. Through prioritizing sustainability and energy efficiency, agrivoltaics embody a win-win situation. Agrivoltaics is only becoming more popular. According to the U.S. Department of Energy, solar energy could jump from providing 4 percent of the U.S. electrical supply to 40 percent by 2035. Moreover, policy across the United States from Colorado to New York is working to increase awareness, research, and usage of agrivoltaics systems, amplifying it as the future of sustainable agriculture.

Solar Power World By Aaron Gomolak, CEO, Ampt | Since its passage, the One Big Beautiful Bill Act (OBBBA) has introduced new constraints for companies seeking clean energy tax credits, requiring projects to meet both domestic content thresholds and foreign entity of concern (FEOC) sourcing restrictions. Together, these provisions have compressed eligibility timelines, created new cost considerations related to higher-priced non-FEOC equipment and generated procurement, supply chain and system design issues. Credit: iStock FEOC restrictions are primarily directed at modules and components sourced from Chinese manufacturers, which have historically supplied the majority of utility-scale PV equipment in the U.S. market. With the July 4 beginning-of-construction and safe harbor deadline approaching, developers and EPCs are racing to find approaches that remain compliant with the new law while still capturing as much of the FEOC cost advantage as possible and meeting project timelines. One strategy gaining traction is blended module procurement, combining FEOC and non-FEOC modules within the same project. Done correctly, this approach improves supply flexibility, reduces cost pressure and preserves a pathway to achieving FEOC-compliance, domestic content and full investment tax credit (ITC) eligibility. Done incorrectly, it can eliminate tens of millions of dollars in credit value. The OBBBA introduced two distinct compliance considerations for projects looking to secure §48E ITC and §45Y PTC. Both are important and must be properly addressed to receive full credit value, but they carry different consequences when missed. The FEOC material assistance restriction disqualifies a project from claiming tax credits entirely if prohibited foreign entity (PFE)-sourced manufactured product costs exceed a statutory threshold. The compliance calculation, known as the material assistance cost ratio (MACR), requires that non-PFE sourced costs represent at least 40% of total manufactured product costs in 2026, rising annually to 45% in 2027, and 50% in 2028. For energy storage, the threshold jumps from 55% in 2026 to 60% in 2027, and then 65% in 2028. The domestic content bonus adds 10 percentage points to the base credit rate for projects sourcing enough manufactured products from U.S. suppliers. The current 2026 threshold is 50% U.S.-origin cost, which is set to rise to 55% in 2027. Failing to meet this threshold forfeits the adder but not the base credit. Most developers have remained focused on project-level FEOC and domestic content calculations. However, the regulatory text points to something stricter. The final IRS regulations under §45Y and §48E define a unit of qualified facility as all solar panels connected to a common inverter. The MACR statute cross-references the same definition. This means that in a utility-scale project with dozens or hundreds of central inverters, each inverter block is its own compliance unit, not the project as a whole. The OBBBA’s material assistance provisions apply to each “qualified facility” as defined under §48E, which adopts this same unit definition. IRS Notice 2026-15, which is the primary FEOC compliance guidance issued under the OBBBA, confirms that a separate MACR calculation is required for each qualified facility, meaning per-inverter-block compliance is the operative standard. Per-inverter-block compliance should also mean project-level compliance, so designing for the former is key. Designing for project-level compliance and being inaccurate exposes every non-compliant inverter block to credit disqualification. This creates an asymmetry that strongly favors treating the inverter block as the compliance unit immediately. Practically, this creates a problem for blended procurement strategies. Without a solution that enables FEOC and non-FEOC modules to be mixed on the same inverter block, the only two viable architectures are: Mixing FEOC and non-FEOC modules from different manufacturers on the same inverter is not straightforward in a conventional central inverter system. Two technical problems arise: First, string mismatch occurs because modules from different manufacturers have different electrical characteristics, including current output, temperature coefficients and degradation profiles. In a central inverter system, mismatched strings in parallel force the inverter’s single MPPT to find a compromise operating point, reducing energy yield across all strings. Second, reverse current damage can occur when a higher-current string drives current backward through a lower-current string in a parallel-connected configuration, potentially damaging bypass diodes and cells. This risk grows as the two module populations age at different rates over the asset life. It may also put module warranties at risk. Addressing these issues is necessary to preserve system performance, reliability and long-term project economics while navigating FEOC and domestic content requirements. Ampt string optimizers are DC/DC converters deployed between the module strings and the combiner box. Each optimizer performs independent maximum power point tracking (MPPT) on its input strings, conditioning each string’s output before it combines with others on the DC bus. This eliminates the direct parallel electrical connection between dissimilar strings, removing mismatch losses and reverse current risk. The result is that FEOC and non-FEOC modules can be placed on the same central inverter block without electrical performance penalty, regardless of differences in manufacturer specifications or long-term degradation profiles. Every inverter block can be designed to satisfy both the per-inverter MACR threshold and the domestic content bonus threshold simultaneously. Optimizers can be deployed across all strings to enable blending of FEOC and non-FEOC modules on each inverter block, achieving per-inverter FEOC compliance and full eligibility for ITC and the domestic content bonus. Full deployment also captures additional system-level benefits, including reduced electrical balance-of-system cost, inverter and transformer capex savings, improved lifetime energy yield and O&M savings from granular string-level monitoring data that also supports compliance documentation efforts. A partial deployment, for example only on the strings carrying non-FEOC modules, can also achieve the blending capability needed for per-inverter compliance. Ampt has modeled the economic impact of these design decisions across four scenarios for a representative 130-MWDC utility-scale project. The scenarios progress from a 0% FEOC baseline through full optimizer deployment with 70% FEOC module procurement. Based on a 130-MWDC/100-MWAC project, 2026 construction start, $1.10/W installed cost, 30% base ITC, 93.5¢ transfer price, $0.08/W FEOC module price advantage. Scenario B result reflects ITC on non-FEOC blocks only with domestic content bonus lost due to per-inverter test failure on FEOC-dedicated blocks. The four scenarios together frame a range of economic outcomes. Scenario A — all non-FEOC modules, no optimizer — achieves full ITC and domestic content bonus eligibility but forfeits the procurement cost advantage that FEOC modules offer. At scale, that forgone savings represents millions of dollars in higher module costs relative to a blended procurement strategy. Scenario B captures the FEOC module cost advantage by having FEOC and non-FEOC modules on separate inverter blocks but ends up with only ITC qualification on the non-FEOC inverter blocks and loses the domestic content bonus altogether, producing the worst outcome of the four. Scenarios C and D use string optimizers to blend modules on each inverter block enabling full ITC and domestic content bonus eligibility while also capturing FEOC module procurement savings. In the case of the full deployment of optimizers in scenario D, there are additional system-level cost savings and energy production benefits. Both optimizer scenarios generate materially higher total value than the others. A full technical paper detailing the compliance framework, the engineering basis for the blending solution and the complete four-scenario value analysis is available by contacting Ampt or downloading online. Developers with specific project configurations are welcome to reach out to Ampt for a project-specific compliance and value analysis. As the July 2026 safe harbor and construction deadline approaches, utility-scale developers can no longer treat FEOC compliance, domestic content strategy and system design as separate workstreams. The regulatory framework links all three, and the financial consequences of misalignment can be worth tens of millions of dollars. Yet, proactive design strategies that enable cost-effective blending of FEOC and non-FEOC modules, without compromising performance, reliability or compliance, are the practical path to preserving full tax credit eligibility and maximizing project value.
