SunPower’s Cobalt Power Systems and Wunder Power Complete Advanced Solar System at San Francisco’s Waterfront Plaza – markets.businessinsider.com

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.

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.”

Another solar farm for Jarrettsville – WMAR 2 News Baltimore

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.

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. (Fj) (IAAS/LAN)

We firmly believe that the internet should be available and accessible to anyone, and are committed to providing a website that is accessible to the widest possible audience, regardless of circumstance and ability.
To fulfill this, we aim to adhere as strictly as possible to the World Wide Web Consortium’s (W3C) Web Content Accessibility Guidelines 2.1 (WCAG 2.1) at the AA level. These guidelines explain how to make web content accessible to people with a wide array of disabilities. Complying with those guidelines helps us ensure that the website is accessible to all people: blind people, people with motor impairments, visual impairment, cognitive disabilities, and more.
This website utilizes various technologies that are meant to make it as accessible as possible at all times. We utilize an accessibility interface that allows persons with specific disabilities to adjust the website’s UI (user interface) and design it to their personal needs.
Additionally, the website utilizes an AI-based application that runs in the background and optimizes its accessibility level constantly. This application remediates the website’s HTML, adapts Its functionality and behavior for screen-readers used by the blind users, and for keyboard functions used by individuals with motor impairments.
If you’ve found a malfunction or have ideas for improvement, we’ll be happy to hear from you. You can reach out to the website’s operators by using the following email
Our website implements the ARIA attributes (Accessible Rich Internet Applications) technique, alongside various different behavioral changes, to ensure blind users visiting with screen-readers are able to read, comprehend, and enjoy the website’s functions. As soon as a user with a screen-reader enters your site, they immediately receive a prompt to enter the Screen-Reader Profile so they can browse and operate your site effectively. Here’s how our website covers some of the most important screen-reader requirements, alongside console screenshots of code examples:
Screen-reader optimization: we run a background process that learns the website’s components from top to bottom, to ensure ongoing compliance even when updating the website. In this process, we provide screen-readers with meaningful data using the ARIA set of attributes. For example, we provide accurate form labels; descriptions for actionable icons (social media icons, search icons, cart icons, etc.); validation guidance for form inputs; element roles such as buttons, menus, modal dialogues (popups), and others. Additionally, the background process scans all the website’s images and provides an accurate and meaningful image-object-recognition-based description as an ALT (alternate text) tag for images that are not described. It will also extract texts that are embedded within the image, using an OCR (optical character recognition) technology. To turn on screen-reader adjustments at any time, users need only to press the Alt+1 keyboard combination. Screen-reader users also get automatic announcements to turn the Screen-reader mode on as soon as they enter the website.
These adjustments are compatible with all popular screen readers, including JAWS and NVDA.
Keyboard navigation optimization: The background process also adjusts the website’s HTML, and adds various behaviors using JavaScript code to make the website operable by the keyboard. This includes the ability to navigate the website using the Tab and Shift+Tab keys, operate dropdowns with the arrow keys, close them with Esc, trigger buttons and links using the Enter key, navigate between radio and checkbox elements using the arrow keys, and fill them in with the Spacebar or Enter key.Additionally, keyboard users will find quick-navigation and content-skip menus, available at any time by clicking Alt+1, or as the first elements of the site while navigating with the keyboard. The background process also handles triggered popups by moving the keyboard focus towards them as soon as they appear, and not allow the focus drift outside it.
Users can also use shortcuts such as “M” (menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
We aim to support the widest array of browsers and assistive technologies as possible, so our users can choose the best fitting tools for them, with as few limitations as possible. Therefore, we have worked very hard to be able to support all major systems that comprise over 95% of the user market share including Google Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, JAWS and NVDA (screen readers).
Despite our very best efforts to allow anybody to adjust the website to their needs. There may still be pages or sections that are not fully accessible, are in the process of becoming accessible, or are lacking an adequate technological solution to make them accessible. Still, we are continually improving our accessibility, adding, updating and improving its options and features, and developing and adopting new technologies. All this is meant to reach the optimal level of accessibility, following technological advancements. For any assistance, please reach out to

'Every town can have a wind turbine or solar panels' – BBC

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.
Nicola Killean warned that a ban "may inadvertently push children to less regulated or riskier parts of the internet".
Scotland won their first game in the World Cup finals for 36 years in the early hours of Sunday.

India's Solar Power Surge: A 22% CAGR in the Next Decade – Devdiscourse

India is slated for a significant surge in solar energy demand, projected to grow at a compound annual growth rate (CAGR) of 22% from FY26 to FY35, according to a report by Nuvama. This growth is largely driven by the burgeoning need for power among data centers, which are seeing expansion parallel to India’s economic growth and urbanization.
The report forecasts total power consumption in the country to rise from approximately 1,848 billion units currently to nearly 3,228BU by FY35. Solar power’s contribution to the national grid is expected to climb from 9% in FY26 to 33% by FY35 under base-case conditions, potentially increasing to 37% in a more optimistic scenario.
Furthermore, electricity costs make up 30-40% of data centers’ operating expenses, compelling operators to adopt renewable energy sources like solar to cut costs and emissions. As data centers expand in tandem with advancements in AI models and computing regulations, the demand for solar capacity is expected to grow, with green hydrogen and data center industries driving an incremental capacity of 416GW in the base case by FY35.

Trump tried to kill solar’s 5% safe harbor, a federal court brought it back – Electrek

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. Get yourself an expert, and get what your democratically elected leaders decided you have coming to you.

Bad Kleinkirchheim Locks In €60,000 In State Funding For Expansive Solar Initiative – Snow Industry News

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.

MPC Energy Solutions’ solar plant in Guatemala enters testing and commissioning phase – TradingView

Key takeaways:
Amsterdam / Oslo – 15 June 2026 – MPC Energy Solutions NV (“MPCES”, “The Company”) today announced that its 66.1 MWp San Patricio solar photovoltaic (PV) plant in Guatemala has secured its final permit and has entered the testing and commissioning phase. The testing will start in the coming days and is then expected to take approximately two weeks. Following successful completion of the testing phase, the plant is anticipated to receive its Commercial Operation Date (COD) certificate during the month of July. Consequently, MPCES revised its timeline for starting operations from the originally guided second quarter of 2026 into the third quarter of 2026.
MPCES will be able to sell the energy generated during the testing phase and period until official COD through the spot market. Reaching COD will mark a key milestone for the San Patricio project and also represents a critical step toward the closing of the planned sale of the asset.
As a result of the delay into the third quarter, additional debt service payments, on-site staff commitments and operational expenses will have to be met, and the Company made an additional capital contribution of USD 1.5 million to cover the final stage of the project until COD. MPCES expects that nearly the entire amount of this additional funding will be recovered through proceeds from the agreed sale of the plant from contractually agreed closing adjustments to the purchase price.

Study Shows TOPCon Modules Outperform BC Technology in Power Generation Photograph: (Archive)
A four-year field study conducted at China’s National Photovoltaic and Energy Storage Demonstration Platform in Daqing has found that N-type TOPCon solar modules consistently outperformed N-type Back Contact (BC) modules in power generation, with the performance gap widening over time.
Located in Heilongjiang Province, the Daqing testing base operates under challenging climatic conditions characterized by low temperatures and high solar irradiance. The site, which has an average annual temperature of 5.5°C and irradiance levels ranging from 900 W/m² to 1,000 W/m², is widely regarded as a representative environment for evaluating the long-term performance, reliability and environmental resilience of photovoltaic technologies.
The first phase of the demonstration project was commissioned in January 2022 and brought together 12 photovoltaic manufacturers and 29 module products with a combined installed capacity of 24.25 MW. The project has since generated four years of continuous operational data under real-world conditions.
According to the latest evaluation, N-type TOPCon modules delivered an average power generation gain of 2.27% per watt compared with N-type BC modules over the four-year monitoring period.
The study also found that the performance advantage of TOPCon technology increased over time. TOPCon modules recorded a power generation gain of 1.39% in 2022, which rose to 2.68% in 2023 and further increased to 3.49% in 2025.
The findings suggest that TOPCon modules not only maintain stable long-term operational performance but also demonstrate sustained improvements in energy yield over extended deployment periods, potentially translating into higher lifetime returns for project developers and asset owners.
The report further highlighted notable performance differences within the TOPCon segment itself. According to the analysis, the gap in power generation between leading TOPCon products and standard TOPCon modules can reach around 2%, underscoring the importance of manufacturing quality, process control and technological expertise in determining field performance.
Among the products evaluated, JinkoSolar’s Tiger Neo series was identified as one of the leading performers. The company attributed the results to its large-scale commercialization of N-type TOPCon technology, mature manufacturing processes and continuous product optimization efforts.
The findings come amid growing competition between TOPCon, BC and other next-generation photovoltaic technologies as manufacturers seek to improve module efficiency, energy yield and long-term project economics.
Industry observers say the Daqing results provide valuable real-world operating data at a time when developers and investors are increasingly focusing on lifetime energy production rather than laboratory efficiency records alone when evaluating solar technologies.

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 region to expand coal-to-oil output in energy security push – The Standard (HK)

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.

Fire strikes another German home with solar roof tiles – pv magazine India

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.

Are Agrivoltaics The Future Of Sustainable Agriculture? – Emagazine.com



—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.

Blending FEOC and non-FEOC modules: The design choice worth millions to your solar project – Solar Power World

Solar Power World
|
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.

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.

Chinese scientists identify degradation pathways in low-silver heterojunction solar cells – pv magazine Global

Researchers from the East China University of Science and Technology have investigated degradation mechanisms in low-silver electrodes used in heterojunction (HJT) solar cells, with the aim of developing design guidelines for manufacturing cost-competitive and high-efficiency photovoltaic modules.
“Our study systematically investigates the thermal aging behavior of silver (Ag)-coated copper (CU) electrodes in heter solar cells, revealing significant increases in contact resistance due to interdiffusion between the Ag and Cu layers,” corresponding author Xiaojun Ye told pv magazine. “It clarifies the underlying degradation mechanisms and provides important guidance for the design of cost-effective and reliable metallization strategies for HJT solar modules.”
The research was based on the premise that the thermal aging behavior of silver-coated copper electrodes is still not fully understood, particularly for thin Ag shells used in commercial pastes. With this in mind, the scientists investigated, in particular, degradation under accelerated aging, linking microstructural evolution and interdiffusion to electrical performance and long-term reliability.
For their experiments, they used a silver-coated copper paste composed of core–shell particles, submicron silver powder, and an epoxy resin matrix, with particles sized 2–4 μm and an around 70 nm Ag shell. It was screen-printed onto n-type monocrystalline silicon wafers, followed by drying at 150 C and curing at 195 C.
The electrical performance of silver-coated copper electrodes was assessed through the transmission line method (TLM), which is a standard technique used to measure electrical properties of semiconductor contacts. In a typical TLM measurement, a set of metal contacts is fabricated on the surface of a sample with varying distances between them. By measuring the total resistance between different contact pairs and analyzing how this resistance changes with spacing, it becomes possible to separate and quantify key parameters such as contact resistivity and sheet resistance.
This approach is especially valuable in solar cell research because it provides a direct way to assess how contact quality changes under different processing conditions or thermal aging, helping researchers understand degradation mechanisms at the interface. It is primarily used to determine line resistance (Rline) – the electrical resistance along a printed or deposited metal line – and contact resistivity (ρc) – how easily current flows across the metal–semiconductor interface
The analysis showed that both Rline and ρc increase with aging time, with a strong dependence on temperature. Moreover, contact resistivity was found to be significantly more sensitive to temperature than Rline, indicating that interfacial degradation is the dominant factor in electrical failure.
Through energy-dispersive X-ray spectroscopy (EDS), focused ion deam–scanning electron microscopy (FIB-SEM), and X-ray Diffraction(XRD) the researchers confirmed that degradation is driven primarily by Ag–Cu interdiffusion and defect formation.
Overall, the research team concluded that the electrical behavior is governed by two competing processes: on one hand, sintering improves particle-to-particle contact and temporarily enhances electrical connectivity; on the other hand, interdiffusion between Ag and Cu, along with defect formation, progressively damages the internal structure.
As aging progresses, the second process overtakes the first, with the originally continuous conductive network breaking apart into isolated and poorly connected pathways, thus forcing electrons to travel through a more tortuous, discontinuous structure. This transition from a well-connected network to a fragmented transport regime is what ultimately drives severe long-term electrical degradation.
“Theoretical analysis indicates that, under practical operating conditions, interfacial diffusion and void evolution are the primary factors governing long-term reliability. Therefore, enhancing interfacial stability is critical for improving device durability,” the academics emphasized.
The research work was presented in the paper “Thermal aging-induced interdiffusion and reliability degradation in low-silver electrodes for SHJ solar cells,” published in Solar Energy Materials and Solar Cells. “Our findings offer critical insights for balancing silver reduction with long-term module reliability in HJT technology.”

Sangamon County board rejects solar farm – Capitol City Now

Business report also includes data centers and Vinegar Hill.
Springfield, IL (CAPITOL CITY NOW) – Data centers are not the only controversial projects in county governments around here. The Sangamon County Board has turned down a proposed solar farm.

Michelle Ownbey, executive editor of the Springfield Business Journal, told the WTAX Morning Newswatch. “This is going to be very interesting from a legal standpoint. The Sangamon County Board’s own attorney told them that, were they to reject this solar project, the developer would have a very strong case in court, but the board basically said, watch this, and did it anyway.”
As for data centers, Ownbey said, “Logan County just enacted a twelve-month moratorium, kicking the can down the road, but the developer for a proposed project there has not said whether they plan to stick around or file legal challenges.”
A data center is planned about two miles west of Taylorville. Ownbey said, “It is anticipated to be ten times more expensive to build than the Cyrus One project here in Sangamon County. Critics are already alleging that the board and the developer have not been forthcoming about private discussions and the potential impact of the project. And the developer is claiming it will create 500 jobs paying six figures a year. I don’t know, that sounds like it might be in the ‘too good to be true’ category.”
A representative of that Christian County development emailed Capitol City Now to take issue with Ownbey’s remarks. Said Jennifer Handshaw of iMiller Public Relations:

 

There is also news about the Conn Hospitality Group‘s unwinding of some of its properties. It had placed Vinegar Hill Mall and the adjacent DeWitt-Wickliffe-Smith mansion up for auction.

The solar grid-lock: Why Rhode Island’s project siting corridors matter for developers – pv magazine USA

Despite being the smallest state by land area in the U.S., Rhode Island packs a punch in utility-scale solar development. A new study out of the University of Rhode Island revealed that the state’s 119 ground-mounted solar projects sized 1 MW and larger are heavily clustered into tight, overlapping corridors.
The study found that solar deployment is not distributed evenly. Instead, projects are packing tightly within specific zones inside Kent and Providence counties.
While early developers likely flocked to these areas due to favorable local zoning or open terrain, that geographic consolidation creates a massive headache for the next wave of projects: 
The University of Rhode Island’s study found that the median distance between a solar farm and its nearest neighbor is just 1,531 meters.
When solar projects aggregate in distinct geographic pockets, the localized community impact multiplies. Instead of a single town dealing with an isolated project, entire multi-town regions are watching large tracts of land transition to solar infrastructure. The study warns that this hyper-concentration of projects gives local opposition groups ammunition, leading to stricter local ordinances, moratoriums, and complex permitting hurdles.
Because these clusters routinely cross over municipal borders, the study notes that traditional town-by-town zoning reviews are ill-equipped to process the regional requirements of utility-scale solar expansion.
The report suggests early market opportunities of “low-hanging fruit” in established solar hotspots is hitting a wall. To dodge localized grid saturation and fierce permitting pushback, developers must look past individual municipal zoning maps.
Winning in compact markets will require shifting toward sophisticated regional planning, targeting unclustered territories, and anticipating where the next regional development corridors will form before the local grid locks up. Find the full spatial analysis here.

Pseudo-planar heterojunction organic solar cell achieves world record efficiency of 20.21% – pv magazine Global

A research team from China has proposed a novel interfacial buffering strategy for pseudo-planar heterojunction (PPHJ) organic solar cells (OSCs), aiming to improve device stability and fabrication reliability. PPHJ architectures, which combine features of both planar and bulk heterojunction designs, are widely used in high-performance OSCs because they enable efficient charge separation while maintaining relatively well-defined donor–acceptor interfaces.
PPHJ cells are typically fabricated via layer-by-layer (LBL) deposition, in which donor and acceptor materials are sequentially deposited. This creates a favorable vertical phase separation that promotes charge transport and exciton dissociation. However, during acceptor deposition, the solvent can swell or partially dissolve the underlying donor layer, causing excessive intermixing, degraded morphology, increased recombination, and reduced device performance. The proposed interfacial buffering strategy introduces a protective layer that minimizes direct solvent–donor interaction, preserving film integrity and enabling more controlled and reproducible interface formation.
“Here, a simple approach for incorporating a highly crystalline polymer as a buffer layer between the donor and acceptor layers is proposed,” the researchers said.
The group incorporated a highly crystalline polymer called D18 as a buffer layer between the donor and acceptor layers in three different cell designs: PM6/L8-BO, PM6:D18/L8-BO, and PM6/D18/L8-BO.
To create the PM6/D18/L8-BO architecture, they first spin-coated a PM6 donor layer onto a 2PACz-coated indium tin oxide (ITO) substrate. Next, a thin D18 layer was deposited on top of the PM6, forming a crystalline solvent-resistant barrier. The L8-BO acceptor layer was then spin-coated onto the D18 layer, followed by post-treatment and thermal annealing. Finally, a electron-transport layer made of a n-type interfacial layer material knonw as PDINN and a silver electrode were deposited, resulting in a device structure of ITO/2PACz/PM6/D18/L8-BO/PDINN/Ag.
The PM6/L8-BO and PM6:D18/L8-BO devices were fabricated as reference cells. The PM6/L8-BO structure represented a conventional LBL device without protection against solvent erosion, whereas PM6:D18/L8-BO was used to assess the effect of directly blending D18 into the donor layer. These active layers were incorporated into the same device architecture, resulting in ITO/2PACz/PM6/L8-BO/PDINN/Ag and ITO/2PACz/PM6:D18/L8-BO/PDINN/Ag devices, respectively.
The PM6/D18/L8-BO-based device was found to achieve a superior power conversion efficiency of 19.80%, surpassing both the conventional PM6/L8-BO device (18.53%) and the PM6:D18/L8-BO architecture (19.21%), where D18 was directly blended into the donor phase. According to the team, the optimized morphology enhances exciton generation and separation while simultaneously reducing interfacial trap states and suppressing non-radiative energy losses. It also facilitates faster hole transfer kinetics and extends carrier lifetimes, indicating improved charge transport and reduced recombination.
Building on these results, the researchers further incorporated a non-fullerene small-molecule acceptor (NFA) known as BTP-eC9 into the PM6/D18/L8-BO active layer by pre-blending it with the L8-BO acceptor prior to deposition. This additional modification led to a further increase in device performance, reaching an efficiency of 20.21%, which the authors highlight as one of the highest reported efficiencies for pseudo-planar heterojunction (PPHJ) organic solar cells.
“Overall, this work highlights a simple yet effective approach to simultaneously regulate the active layer morphology and enhance the device performance, offering practical insights for the scalable fabrication of high-performance PPHJ OSCs with precisely controlled vertical phase separation (VPS) morphology,” the academics concluded.
The cell design was described in “Erosion-immune Layer-by-layer Deposition Enabled by Interfacial Buffering toward 20.21%-Efficient Pseudo-Planar Heterojunction Organic Solar Cells,” published in the Chinese Journal of Polymer Science. Researchers from China’s Jiangxi Normal University, Zhejiang University, Chinese University of Hong Kong, Changzhou University, and Gannan Normal University have contributed to the research.

According to the latest IndexBox report on the global Roof Flashing Kits for Solar Modules market, the market enters 2026 with broader demand fundamentals, more disciplined procurement behavior, and a more regionally diversified supply architecture.
The World Roof Flashing Kits for Solar Modules market is entering a sustained growth phase, with projections indicating a compound annual growth rate (CAGR) in the range of 8–13% from 2026 to 2035. This expansion is fundamentally tied to the accelerating global deployment of rooftop solar photovoltaic (PV) capacity, which is expected to more than double over the forecast period. Roof flashing kits, which provide a critical weatherproof seal around roof penetrations for solar module mounts, are an essential, non-discretionary component of any rooftop installation. As building codes worldwide tighten requirements for fire safety, wind uplift resistance, and moisture barriers, the specification and adoption of high-quality, certified flashing kits are becoming mandatory rather than optional. The market is currently valued at approximately USD 1.2 billion in 2025, with residential and small commercial installations accounting for roughly 60–65% of total unit demand. Replacement and retrofit demand, while currently representing 10–18% of volumes, is growing faster than new installations as early solar arrays from the 2010s begin to age and require maintenance. Material costs, particularly for aluminum extrusions and stainless steel, remain a key variable influencing pricing and margins. The market is also witnessing a shift toward integrated, pre-assembled kits that reduce on-roof installation time by an estimated 20–30%, driving procurement toward bundled solutions. Regionalization of supply chains is accelerating, with manufacturers establishing local production facilities in North America, Europe, and India to mitigate trade tariff exposure and shorten lead times. Digital design tools, including solar-specific CAD plugins and automated bill-of-material generators, are bec
The baseline scenario for the World Roof Flashing Kits for Solar Modules market through 2035 is one of robust, sustained growth, underpinned by structural demand drivers that are largely independent of short-term economic cycles. The primary engine remains the global expansion of rooftop solar PV capacity, which is projected to grow at a CAGR of 10–15% over the forecast period, driven by falling solar panel costs, government incentives, and corporate renewable energy targets. As of 2025, the market is estimated at USD 1.2 billion, with volumes expected to reach approximately USD 3.0–4.5 billion by 2035 in nominal terms, assuming a mid-range CAGR of 10.5%. The market index (2025=100) is projected to reach 270 by 2035, reflecting a near-tripling of demand. The residential segment will continue to dominate, accounting for 55–65% of kit volumes, but the commercial and industrial (C&I) segment is expected to grow faster as large warehouse and factory rooftops are increasingly utilized for solar generation. Replacement and retrofit demand will become a significant growth vector, particularly after 2030, as the first wave of residential solar installations from the 2010s reaches 15–20 years of age and requires flashing replacement due to seal degradation. Material costs, especially for aluminum, will remain a key variable; however, the trend toward integrated, pre-assembled kits is expected to improve margins for manufacturers by reducing SKU complexity and enabling higher value-add pricing. Regional dynamics will shift, with Asia-Pacific maintaining the largest share (40–45%) due to massive rooftop solar programs in China, India, and Southeast Asia, while North America and Europe will see above-average growth rates driven by regulatory mandates and retrofit demand. Trade flow
The residential segment is the largest consumer of roof flashing kits, accounting for approximately 58% of global demand.

Ann Arbor to purchase over 8,000 solar panels for SEU installation – WEMU

The Ann Arbor City Council will vote tonight to spend nearly $1 million for the purchase and storage of solar panels for the Sustainable Energy Utility.
The city is set to buy over 6,800 Solar PV modules from New York-based Samba Energy. They’re to be installed at participating SEU locations in Ann Arbor beginning in 2028.
SEU Executive Director Shoshannah Lenski says it’s a major milestone for the utility.
Lenski says that will help secure $3 million in tax credits, which will be critical in keeping solar rates affordable. She says they are preparing to serve hundreds of residents in the coming years.

Nature Sustainability (2026)
Harnessing rooftop photovoltaic (RPV) generation to power electric vehicles (EVs) can substantially accelerate the renewable energy transition and carbon mitigation. Yet, the mismatch between electricity generation and charging demand, exacerbated by rapid EV adoption, introduces large uncertainties in charging capacity, economic feasibility and decarbonization potential. Here we assess the spatiotemporal scalability of PV-powered EV charging across 40 global cities, analysing 3.38 billion charging records from 22,000 charging piles. Under three charging strategies, influential factors affecting daily charging capacity (generation-to-demand ratio) across all urban microgrids of varying sizes consistently followed an exponential scaling law. By 2050, RPV generation is projected to double in each city (1.6–434.7 TWh yr−1), supported by rooftop area expansions aligned with the shared socioeconomic pathways and charging demand will rise 4–1,759-fold (1.5–10,451.7 GWh yr−1), driven by increased EV adoption under International Energy Agency scenarios. Under these evolving conditions, the annual charging capacity of each city declines but remains sufficient to meet 2050 charging demands. Across all cities, total revenue is projected at US$3,173.2 (±99.5) billion with accumulative carbon mitigation of 11.9(±0.4) Gt from 2025 to 2050. These results suggest that RPV-powered EV charging can remain economically viable and sufficient to meet growing demand across diverse urban settings through 2050.

The top-down stage predicts the daily EV charging demand by applying a federated meta-learning framework and estimates the RPV electricity generation to explore the spatial patterns of daily solar EV charging capacity. The bottom-up stage uses an integrated scenario framework to estimate the projected annual EV charging capacity and derive the economic feasibility, enabling the assessment of carbon mitigation potential by 2050.
Several cities experienced dramatic increases in EVCDs, such as AMS, BER, CPH, DUB, etc. This is because the installation of new charging stations immediately followed by intensive charging demands, revealed from the geospatial analysis investigating the locations of charging stations over time. Large variations of the real EVCD imply great challenges in accurately forecasting daily EVCD at each station.
Source data
The prediction and observation values were normalised between 0 and 1 for easy comparison. The linear regression fits are shown with 95% confidence intervals (light red bands). EVS and R2 are close to 1 and the biases are notably small, demonstrating outstanding performance in daily EVCD forecasting for the investigated cities.
Source data
a, The microgrids are modelled by a set of hexagons with the edge length r equalling 2 km. The maps show noticeably heterogeneous distributions of EV charging stations across cities, in terms of the number of charging stations, their density, and location. b, Annual mean charging capacities (a dimensionless quantity) vary from hundreds to a few thousand under the MES strategy. c, Annual mean charging capacities are around hundreds of thousands under the woESS strategy. There were three microgrids in Shenzhen (SZH) that did not produce rooftop PVEG as rooftops were unavailable in these regions.
a, Regression under the AES strategy. b, Regression under the MES strategy. φ* and (rm{cc}_{m}^{* }) represent the mean ln(φ) and the mean ln(ccm) across all 40 cities, respectively, at a given resolution of microgrids. Statistical significance was assessed by using two-sided Pearson correlation across the eight resolution-level aggregated data points (n = 8, df = 6). No adjustment for multiple comparisons was made. Pearson correlation coefficients (R) and p-values are shown in the plots. For AES, a strong negative correlation between φ* and (rm{cc}_{m}^{* }) was observed (95% confidence interval, in [ − 0.993, − 0.795]; t(6) = − 8.54). For MES, a similarly strong negative correlation was observed (95% confidence interval in [ − 0.997, − 0.904]; t(6) = − 12.95).
Source data
The scatter plots show strong positive correlations between ln(φ) and ln(ccm), with Pearson correlation coefficient (R) ranging between 0.53 and 0.64 (p < 0.0005) when r varies from 2 km and 16 km. Statistical significance was assessed for each plot using two-sided Pearson correlation across 40 cities (n = 40, df = 38). No adjustment for multiple comparisons was made. The 95% confidence interval and t statistics are [0.270, 0.723] and 3.86 for r = 2 km, [0.279, 0.728] and 3.93 for r = 4 km, [0.32, 0.764] and 4.48 for r = 6 km, [0.432, 0.804] and 5.31 for r = 8 km, [0.303, 0.742] and 4.13 for r = 10 km, [0.372, 0.774] and 4.73 for r = 12 km, [0.362, 0.769] and 4.66 for r = 14 km, and [0.410, 0.796] and 5.15 for r = 16 km.
Source data
The bar plot shows that the charging demands under the APS are larger than under the STEPS. Surprisingly, 6 cities are expected to grow more than 100 times, followed by 5 cities between 50 and 100 times, 15 cities between 25 and 50 times, and the remaining 14 cities smaller than 25 times.
Source data
ae, The bar plots show the differences in annual Eg across five SSPs and present large differences across cities under the same scenario, with the smallest demand around 1.10-1.31 TWh yr−1 in RVK and the largest demand around 323.13-447.72 TWh yr−1 in LOA in 2050.
Source data
a,b, cca under the SSP2. c,d, cca under the SSP3. e,f, cca under the SSP4. g,h, cca under the SSP5. Overall, cca is the largest under the SSP5, followed by SSP2, SSP4, and SSP3, which indicates the most substantial urbanisation and consequently, the largest rooftop area expansion and PVEG. cca is smaller under the APS than STEPS since APS suggests a larger penetration of EVs and thus, a larger EVCD.
Source data
a,b,c, LOA, SZH, MEL, SPO, and DBA under the SSP5 obtain the largest carbon mitigation from RPVs, followed by SSP1, SSP2, SSP4, and SSP3. d,e,f, SZH, MEL, SYD, MIL, and LDN under the APS (Gasoline) achieve the largest carbon mitigation from EVs, followed by APS (Diesel), STEPS (Gasoline), and STEPS (Diesel). g,h,i, SZH, MSL, SYD, TLV, BER under the APS make the largest carbon emission from ESSs, compared to the STEPS.

California doubles down on ‘unworkable’ community solar program – pv magazine Global

The CPUC voted to advance a community solar program that solar industry members are calling “unworkable.” The Solar Energy Industries Association (SEIA) says “virtually ensures” that no new community solar projects will be developed in the state under current structure. 
Rather than creating a viable path for new, independent projects, the commission chose to implement portions of its community solar program using an existing, utility-controlled pricing structure. According to solar industry advocates and the advocacy group Californians for Local, Affordable Solar and Storage (CLASS), the regulatory decision essentially hands the keys back to the state’s investor-owned utility monopolies, the same utilities that have spent years working to ensure community solar never gets built. 
The CPUC’s decision relies on the existing Renewable Market Adjusting Tariff (ReMAT) pricing structure to determine grid export compensation rates, rejecting the solar industry-backed Net Value Billing Tariff model. SEIA and other industry advocates argue the rate structure makes building community solar a losing proposition for any business, ensuring projects won’t be built. 
In most U.S. community solar programs, subscribers, including homeowners and businesses, pay a discounted monthly fee for a share of a remote solar farm’s energy and receive larger credits on their standard utility bill for the electricity that share produces, typically resulting in a net savings of 5% to 20%. However, in California’s approved program, the rate paid by utilities to solar developers is too low, which stifles the creation of projects and ultimately leaves subscribers with nothing to sign up for 
Commission officials, including CPUC President John Reynolds, stated the move ensures the program grows responsibly by balancing affordability, equity, and grid reliability so non-participating customers do not pay more than the avoided wholesale cost of the generated electricity. However, clean energy groups argue the baseline wholesale metrics are far too low, destroying the predictable market economics needed to secure private capital and make new project construction viable for developers. 
The approved framework also relies on one-time federal funding, specifically the $250 million federal Solar for All grant money awarded to California. Advocates state that by packaging this federal money into an utility-led model rather than a scalable market-based program, the CPUC is effectively forfeiting the funding’s potential and dooming future deployment. 
“Today’s vote is a doubling down on failure,” said Derek Chernow, Executive Director of CLASS. “In the midst of an affordability crisis and rising utility rates, the CPUC has once again handed the keys to the utilities and called it a program. California ratepayers are drowning in electricity bills. The Legislature passed AB 2316 four years ago with clear direction to deliver a workable community solar and storage program. Instead, the CPUC produced a program that got zero projects built, forfeited $250 million in federal Solar for All funding, and is now being voted through again in essentially the same packaging.” 
The regulatory gridlock leaves California ratepayers completely cut off from bill relief during a period of record-high energy prices. While families, renters, and small businesses across the Central Valley continue to face soaring electricity costs, more than 20 other states have successfully deployed market-based community solar programs that actively save consumers money. 
With the CPUC maintaining its focus on utility-backed positions to avoid cost-shifting to non-participating customers, solar advocates argue the regulatory route through the commission is officially a dead end. 
Clean energy advocates are redirecting their efforts to the state legislature, pushing for the immediate passage of AB 1813 in the Senate to bypass the CPUC’s framework entirely and establish a functional, financeable community solar program by law.

U.S. deploys 7.8 GW of solar in Q1 – pv magazine Global

According to the SEIA/Wood Mackenzie US Solar Market Insight Q2 2026 report, the United States solar industry installed 7.8 gigawatts direct current (GWdc) of capacity in the first quarter of 2026. This represents a 27% decline compared to the first quarter of 2025 and a 42% decline compared to the fourth quarter of 2025, following typical industry seasonality. 
Even with this decline, solar by itself accounted for 60% of all new electricity-generating capacity added to the grid during the quarter. When combined with battery storage, the two technologies accounted for 91% of all new domestic capacity additions in the first quarter. 
 On a state level, installation rankings for the first quarter of 2026 were led by Texas in the first position with 1,591 MWdc, followed by Florida with 1,044 MWdc, Ohio with 617 MWdc, Indiana in fourth, and California in fifth.
Utility-scale 
The utility-scale segment remained the largest market driver by deploying 5.9 GWdc in the first quarter of 2026. While this reflects a 34% drop year-over-year and a 45% reduction quarter-over-quarter, underlying contracting activity expanded significantly. Developers signed 6.3 GWdc of utility capacity agreements during the quarter, marking a 15% increase year-over-year. The surge in contracting was driven primarily by projects in Texas, with offtake agreements led by data and technology companies.  
Looking ahead, a total utility-scale pipeline of 216 GWdc supports a strong buildout through 2030, though near-term capacity additions face constraints from permitting headwinds.  
Specifically, a memorandum from the Department of the Interior regarding solar and wind development is estimated to be affecting roughly 30% of the early-stage utility solar project pipeline, said the report. Over the longer term, Wood Mackenzie forecasts that the utility-scale segment will add 211 GWdc between 2026 and 2031. 
Residential 
The distributed generation segments recorded divergent trends in the first quarter. The residential segment installed 1,179 MWdc of capacity, achieving a 6% increase year-over-year, though dropping 15% from the final quarter of 2025. Residential volumes were temporarily buoyed by an overflow of installations that had been initiated at the end of 2025 so customer-owned projects could qualify for the expiring Section 25D tax credit.  
California, Florida, and Illinois led the residential rankings, with Florida and Illinois posting their strongest quarters since the end of 2024.  
However, following the bankruptcy of the second largest national installer, updated permitting data, and tighter tax equity availability, the residential market is projected to experience a 21% contraction over the full year of 2026. The market is expected to return to growth in 2027, expanding at an average annual rate of 6% through 2031, supported by prepaid offerings and third-party ownership (TPO) projects utilizing safe harbor strategies. 
Commercial and industrial 
The commercial solar segment secured its second-highest first quarter on record by installing 523 MWdc. This represents a minor 4% decline year-over-year and a 25% drop quarter-over-quarter.  
California dominated this space by adding 201 MWdc, making up 38% of the national total as legacy NEM 2.0 projects continued to come online before an April 2026 installation deadline. Illinois and Pennsylvania followed in commercial performance, contributing 49 MWdc and 40 MWdc respectively.  
The commercial market is projected to contract later in 2026 due to California’s tariff transition and interconnection delays in legacy markets like New York and Massachusetts , before rebounding between 2028 and 2030 as developers rush to build out safe-harbored projects.  
Community 
The community solar segment installed 247 MWdc in the first quarter, representing a 4% year-over-year decline and a 67% plunge quarter-over-quarter.  
New York drove the bulk of this decline, dropping 46% year-over-year to 61 MWdc. Despite this, an 8.2 GWdc project pipeline and improved queue efficiencies in Illinois and New York are projected to drive a 1% national community solar expansion in 2026 to reach roughly 1.7 GWdc. 
Manufacturing 
From a supply chain and manufacturing standpoint, no new module manufacturing capacity was added in the United States during the first quarter of 2026. While domestic module production has grown historically to cover about 70% of 2025 installation volumes, manufacturers face severe domestic cell shortages.  
The United States possesses only 3 GW of operating cell capacity, forcing module producers to rely heavily on imported cells. Import reliance is further complicated by trade actions, including high preliminary anti-dumping and countervailing tariff rates announced by the Department of Commerce for cells and modules imported from India, Indonesia, and Laos. These three nations, combined with Malaysia, Thailand, and Vietnam, supplied 78% of all US cell imports in 2025.  
Additionally, the industry is grappling with regulatory uncertainty surrounding Prohibited Foreign Entity provisions under the One Big Beautiful Bill Act. Full guidance is delayed, which has forced many manufacturers with ties to China to reorganize under American ownership. Fortunately for developers, a recent quantification shows that a vast majority of the utility-scale pipeline completed safe harboring by the end of 2025, protecting it from these foreign entity requirements. 
Pricing 
National solar system pricing fell across nearly all segments year-over-year in the first quarter, with the exception of commercial solar. Residential system costs fell 7% year-over-year to an average of $3.21 per watt direct current ($/Wdc), down from $3.44/Wdc in the first quarter of 2025. Utility-scale fixed-tilt systems dropped 3% to $0.90/Wdc, down from $0.92/Wdc, while utility single-axis tracking systems fell 3% to $0.99/Wdc, down from $1.02/Wdc.  
Price drops were largely driven by solar module prices decreasing across all segments, including a drop of more than 20% for distributed projects, bringing average module prices down to $0.34/Wdc from $0.43/Wdc the previous year.  
The report found price relief stems primarily from the repeal of International Emergency Economic Powers Act tariffs, which previously placed 20% to 50% duties on certain regions.  
Conversely, commercial solar system pricing bucked this trend by increasing 4% year-over-year to $1.67/Wdc, up from $1.60/Wdc. Cost escalation was caused by a 60% year-over-year surge in equipment costs for both electrical and structural balance-of-system components, driven higher by Section 232 metal tariffs that have impacted imported and domestic equipment prices, said the report. 
Looking ahead 
Looking forward, the five-year outlook for the United States solar industry has been revised upward by 1.4%. 
While this long-term trend indicates that the cumulative U.S. solar fleet will double over the next five years, it also reflects a stagnation in annual additions. Annual capacity additions are forecast to remain essentially flat, hovering at an average of 43 GW per year through 2031.
The flat trajectory stands in contrast to the previous doubling of the domestic solar fleet, which took only three years to accomplish. Market analysts conclude that despite intensifying power demand across the country, structural constraints like permitting bottlenecks, lengthy equipment lead times, grid interconnection queues, and the ongoing transition into a post-tax-credit environment continue to function as major headwinds limiting further annual expansion.
