The Export-Import Bank of Korea is investing in a 132 MW solar plus 325 MWh battery energy storage project in Guam, being developed by a consortium of Korean developers. December 24, 2025 Patrick Jowett Image: Oskar Kadaksoo, Unsplash The Export-Import Bank of Korea (Eximbank) will provide $241 million in financing for a large-scale solar-plus-storage project in Guam. The Yona solar project will consist of a 132 MW solar power plant and a 325 MWh battery energy storage system, which will be developed in the Yona area in the south of the island. About 200,000 solar panels will be placed on…

Romanian utility Electrica Group is conducting two solar tenders: a 62.5 MW project open for applications until February 17, 2026, and a 77.6 MW project open for bids until February 12, 2026. December 24, 2025 Patrick Jowett Image: Teodora Popa/Unsplash Romanian utility company Electrica Group has published two tenders for solar energy. The first concerns the 62.5 MW Satu Mare 3 project to be built in the municipality of Doba in the northwest of Romania. New Trend Energy SRL, a company wholly owned by Electrica SA, is conducting the tender. According to the invite you to registerThe project is in…

By Martin McConnell December 23, 2025 Clean tomorrow Siting Solutions Projects released its new Site Policy Field Guide on December 18, offering policy models, principles and a “practical framework” for clean energy advocates. The new field guide aims to address siting, which the project claims has become the “largest clean energy bottleneck” in the US. Project officials have centered the guide around designing clean energy advances while also balancing the needs of company stakeholders. “Siting is the bottleneck holding back America’s clean energy potential,” said Alex Breckel, co-author and Senior Director of Programs at the Siting Solutions Project. “With the…

By Martin McConnell December 23, 2025 Several groups with strong interests in clean energy, led by the Oregon Environmental Councilhave sued the IRS and Treasury Department over anti-solar and wind tax guidelines that they say “illegally harm renewable energy.” The lawsuit, filed Dec. 18 in the U.S. District Court for the District of Columbia, includes seven plaintiffs from across the country. The group of plaintiffs has called the new tax rules, specifically the “five percent safe harbor” standard for solar and wind construction, “restrictive and unprecedented.” The new tax credit rule breaks with a decade-long precedent set by the federal…

Saatvik Green Energy has commissioned a 2 GW in-house EPE film production facility at its Ambala campus in Haryana. December 24, 2025 Uma Gupta By pv magazine India Saatvik Green Energy has commissioned a 2 GW in-house EPE film production facility at its Ambala campus in Haryana, India. EPE is a multi-layer encapsulation film that combines ethylene vinyl acetate (EVA) and polyolefin elastomer (POE) for the encapsulation of photovoltaic modules. Saatvik’s recently commissioned EPE facility, located within the existing module manufacturing complex, marks a major milestone in the company’s journey towards deeper vertical integration and supply chain self-reliance. Encapsulation films…

The efficiency result represents one of the best performances achieved to date for this type of thin-film solar cells. The device is manufactured with a contact interface on the back that reportedly improves charge transport. December 24, 2025 Valerie Thompson Researchers from Chonnam National University in South Korea have used vapor processing to deposit a germanium oxide layer on the back contact surface of thin-film tin mon sulfide (SnS) solar cells to improve the energy conversion efficiency of solar cells to 4.81%, up from 3.7% for the standard cell. Although known as a cheap, plentiful material with promising properties for…

Japan plans to impose stricter environmental oversight on future large-scale solar projects. The government may also end financial support under its feed-in tariffs and feed-in premium schemes for large ground-mounted solar from April 2027. December 24, 2025 Patrick Jowett Image: Fumiaki Hayashi/Unsplash The government of Japan plans to take a series of countermeasures against large-scale solar farms. Dubbed the Mega Solar Countermeasure Package, the plans include introducing stricter environmental oversight by lowering the threshold for mandatory environmental impact assessments and expanding their scope. A threshold for this measure has yet to be made public. Japan’s Ministry of Economy, Trade and…

Trina Solar has completed the sale of its 5 GW US solar module factory to T1 Energy, exiting direct manufacturing while retaining a minority stake. December 24, 2025 Vincent Shaw Trina Solar has completed the sale of its 5 GW solar module manufacturing facility in the United States to T1 Energy, completing a transaction first approved by the company’s board of directors in November 2024. The Shanghai-listed manufacturer said in a December 23 filing that all asset transfer and share exchange steps have now been completed. Following the transaction, Trina will own 45.9 million shares in T1 Energy, equivalent to…

Trina Solar says new certified results in perovskite crystalline silicon tandem cells and modules demonstrate progress toward next-generation industrial-scale PV. December 24, 2025 Vincent Shaw Trina Solar said its researchers have achieved new certified benchmarks in perovskite-crystalline silicon tandem solar cell efficiency and module power, which the company described as world records for industrial-sized devices. The company said an industrial-scale tandem solar cell with a half-cut format of 210 mm achieved a certified energy conversion efficiency of 32.6%, while a standard-sized tandem module integrating the cells delivered a peak power of 865 W. Both results have been independently verified by…

Scientists in China have built and tested a device that uses redox couples combined with a single three-junction amorphous-silicon photoelectrode. When tested under a xenon lamp simulating a single sun, the device achieved an average solar energy to electricity conversion efficiency of 4.2%. December 24, 2025 Lior Kahana A research team from China’s Nanjing Tech University (NanjingTech) has developed and built a new anthraquinone-based solar redox flow battery (SRFB) device. The system consists of redox couples known as 2,6-DBEAQ and K4[Fe(CN)6]combined with a single three-junction amorphous silicon photoelectrode. SRFBs are systems that combine a solar cell with a redox flow…
