According to the latest analysis from GlobalData, the US will add between 41 and 52 GW of solar energy annually through 2035. December 31, 2025 Patrick Jowett The USA is on track to deploy 737.8 GW of solar energy by the end of 2035, according to an analysis by the London-based consultancy Global data. GlobalData says the US will add 47.9 GW of solar power in 2025, slightly less than current record of 49 GW deployed in 2024. Annual deployment is then expected to decline, with GlobalData projecting an increase of 42.2 GW of solar in 2026, 44.8 GW in…
The intermittent production of solar energy poses challenges for grid operators who have to balance supply and demand. Traditional numerical weather prediction models often handle cloud initialization poorly, causing ultra-short-term solar irradiance predictions to deteriorate over time. Researchers Min Chen and Liangchen Guo from the Institute of Urban Meteorology of the China Meteorological Administration have built a 0-6 hour ultra-short-term global horizontal radiation forecast system for China by combining data from the Fengyun-4B satellite with the regional numerical forecast model RMAPS-ST. Their work appears in Atmospheric and Oceanic Science Letters in an article titled “Ultra-short-term global horizontal irradiance forecasts in…
A regional government agency in eastern China is considering whether to wind down its multi-billion-yuan joint venture with Eging PV after construction delays and financing disruptions, underscoring mounting pressure in the country’s solar supply chain. December 31, 2025 Vincent Shaw A regional government agency in Chuzhou, China’s Anhui province, has notified Chinese module maker Eging PV of a hearing that could lead to the termination of its flagship expansion project, following lengthy closures and stalled construction plans. In a filing dated Dec. 28, 2025, Eging PV said it had received a hearing from the Quanjiao Economic Development Zone Administrative Committee…
A team of materials scientists has developed a bio-based carbon airgel, derived from chitin, that improves thermal energy storage in shape-stabilized phase-change materials while addressing leakage during melting. Phase change materials store and release heat as they melt and solidify, so they are used in building temperature control, solar thermal storage and electronic thermal management. Many organic phase change materials leak when they melt, which shortens their service life and limits their practical application. In the study published in Sustainable Carbon Materials, researchers converted chitin, a natural polymer found in crustaceans and fungi, into an ultra-light airgel and then carbonized…
The total number of UK PV installations supported by Contracts for Difference (CfD) could more than double by 2026 if developers meet deadlines. The contracting company’s latest investment report shows that solar energy has the largest number of contracts of any generation technology. December 31, 2025 Matthew Lynas The UK’s largest PV installation to date, Cleve Hill, was commissioned in 2025 and has a CfD contract. Image: Quinbrook A record number of UK solar power plants, backed by CfDs, are due to come online in 2026 as contract deadlines kick in following a tender process that saw PV win more…
Outdoor retailer REI Cooperative has announced that it has taken further steps to reduce its impact on the planet. In 2025, REI partnered with several companies to accelerate the development of renewable energy. The company is supporting a 2.5 MW community solar project in Woodbury, Minnesota, developed by American solar energy. The project will reserve 500 spots for low- to moderate-income households to subscribe to renewable energy and add clean power to the grid near REI’s Bloomington store. REI too connected a Virtual Power Purchase Agreement (VPPA) with Carhartt and other outdoor partners to develop an 18.5 MW solar portfolio…
Scientists have developed a floating digital PV twin system, trained on data from 155 physical experiments, using a dual artificial neural network (ANN) with a high-fidelity model and a lower-order model. The predictive performance achieved R2 values of 0.9996 for PV surface temperature and 0.9189 for output power. December 31, 2025 Lior Kahana A research team led by scientists from Britain’s Cranfield University has developed an AI-powered digital twin framework for FPV systems. The system uses a physical FPV twin deployed on a water surface, with sensors transmitting data to the cloud and ultimately to the digital version of the…
Waaree Energies exceeded 20 GW of approved solar panel manufacturing capacity after adding the Chikhli plant to the Indian Ministry of New and Renewable Energy’s (MNRE) Approved List of Models and Manufacturers (ALMM), strengthening domestic supply for utility-scale projects. December 31, 2025 Uma Gupta By pv magazine India Waaree Energies’ Chikhli facility in the Indian state of Gujarat has been added to the MNRE’s ALMM with an approved capacity of 16,444 GW. The listing brings Waaree’s total solar panel manufacturing capacity in India to 20.17 GW, including Indosolar capacity. The updated ALMM entry includes high-efficiency module lines produced in Chikhli,…
Scientists have simulated a residential building based on a real two-storey house in the UK, combining rooftop agrivoltaic energy with on-site hydrogen production. The electricity generated by the solar system is used to produce hydrogen, which is then supplied to a hydrogen vehicle and insulated gasochrome smart windows. December 30, 2025 Lior Kahana A research group at the University of Exeter investigated a modular agricultural voltaic-powered hydrogen production concept for households. Agrivoltaic solar panels on the roof power an electrolyzer that produces hydrogen for hydrogen vehicles and for insulated gasochrome smart windows. The windows are a form of thermally insulating…
Kit Carson Electric Cooperative will collaborate Nuvve Holding Corp. to establish two battery projects in New Mexico. Nuvve will deploy two four-hour, 5 MW battery systems to limit peak loads, provide grid resiliency and market participation through the Western Energy Imbalance Market (WEIM) through Guzman Energy and the PNM Balancing Authority Area. Kit Carson Electric Cooperative (KCEC) will use this battery-as-a-system model to access critical grid infrastructure without upfront capital investments, while transferring ownership, financing, operations, maintenance, expansion and performance responsibilities to Nuvve. The systems will be configured with grid-forming and black-start capabilities, supporting the operation of microgrids during power…
