Earlier this year, Danish investor AIP Management acquired a 49% stake in a 2.4 GWh UK battery energy storage system (BESS) portfolio from UK-headquartered BW ESS.The portfolio includes three projects, including the operational Bramley project and the under-construction Hams Hill and Berkswell projects, which were completed at the end of September. At that time, Solar energy portal revealed the transaction was worth more than £650 millionand was a significant development for AIP’s storage investments, marking the first investment in a UK storage project and the first investment in a standalone storage project, as opposed to projects located next to solar…

Spain’s grid operator has approved 24 renewable energy plants to provide dynamic voltage regulation services from January, making them a priority under a new operational program. October 30, 2025 Pilar Sanchez Molina Image: Haberdoedas, Unsplash By pv magazine Spain Spanish grid operator Red Eléctrica de España (REE) said this week that it has authorized 24 renewable energy facilities to provide dynamic voltage regulation services under Operational Program 7.4 (OP 7.4). The approval follows a request submitted by REE in 2020 and a June decision by the National Commission for Markets and Competition (CNMC) to grant authorization through an urgent resolution.…

EG4’s production facility in Texas. New data from the Solar Energy Industries Association (SEIA) shows that the entire solar supply chain has been redesigned and that U.S. manufacturing capacity has grown in every segment of the solar and storage supply chain. With news of Corning’s new ingot and wafer facility coming online in the third quarter, the United States now has the capacity to produce every major part of the solar supply chain. However, this progress could all be in jeopardy if the Trump administration continues its attacks on solar energy. According to SEIA Solar & Storage Supply Chain DashboardSince…

The Chinese manufacturer claims that back-contact Hi-MO 9 modules outperformed TOPCon counterparts in a six-month offshore test, showing higher power output, better low-light performance and lower operating temperatures. October 30, 2025 Emiliano Bellini Chinese module manufacturer Longi has released the results of a six-month test of its back-contact solar modules deployed in an offshore deep-sea experimental installation. The company said the results, covering the period January-June 2025, were validated by the China National Photovoltaic Product Quality Inspection Center (CPVT). The experimental site, located off the coast of Yantai, a major Chinese port city on the Yellow Sea, houses 10 Longi…

China uses advanced solar telescopes to measure magnetic fields with unprecedented accuracy The Accurate Infrared Magnetic Field Measurements of the Sun (AIMS) are now operational in Lenghu Municipality, Qinghai Province, at an altitude of about 4,000 meters. This solar magnetic field telescope is the first in the world to operate in the mid-infrared wavelength range, marking a significant advance in the direct measurement of the Sun’s magnetic field. For decades, measurements relied on indirect methods, which limited accuracy. AIMS was developed to address these challenges, moving from traditional 100 gauss accuracy to measurements better than 10 gauss accuracy. Deng Yuanyong…
