Germany continues to lead the European battery energy storage market, with 18 GW of utility-scale demand and 8 GW from commercial and industrial applications over the next decade. December 12, 2025 Marija Maisch By ESS news The European BESS market is poised for a major jump in annual additions, with 11 GW deployed in 2024 and an expected 45% increase to 16 GW in 2025, according to Wood Mackenzie. Furthermore, the research and consultancy firm expects European BESS deployment to grow at a compound annual growth rate of 9% over the next decade, reaching 35 GW in 2034. Within this…

REC Group has third-party tested its REC Alpha Pure-RX solar panels for resistance to 45mm hailstones, according to IEC61215 MQT 17 protocols. The industrial baseline requires certification for 25 mm hailstones hitting the front of the panel at 83 km/h. REC says the REC Alpha Pure-RX has demonstrated its strength against 45mm hailstones traveling at 110 km/h, as tested by Changzhou Huayang Inspection and Testing Technology Co., the official laboratory of TÜV SÜD in China. Already certified to IEC 61215 for resistance to 35mm hailstones, the REC Alpha Pure-RX panel was subjected to 44 impacts from 40 and 45 mm…

The Chinese manufacturer said its new Astro 7 TOPCon module has an innovative self-cleaning frame and an energy conversion efficiency of 23.2%. December 12, 2025 Vincent Shaw Astronergy, the solar module unit of China’s Chint Group, has launched Astro N7, a new series of anti-dust modules aimed at the fast-growing residential and commercial rooftop markets. The design aims to maximize generation efficiency and reduce pollution-related losses. The Astro N7 CHSM78RN(DG)/F-BH bifacial module is based on n-type TOPCon cell technology and delivers 725–750 W with a maximum efficiency of 23.2% under standard test conditions. The module uses a 210R rectangular wafer…

Energy think tank Ember says the cost of utility-scale batteries outside China and the United States has fallen to $65/MWh, allowing solar power to be delivered when needed. December 12, 2025 Uma Gupta By pv magazine India Battery costs have fallen sharply over the past two years. A steep decline in 2024 was followed by further declines in 2025, putting storage within reach for dispatchable solar, Ember said. The energy think tank’s analysis, based on October 2025 auctions in Italy, Saudi Arabia and India and interviews with active developers, shows the cost of a fully grid-connected battery system at $125/kWh…

South Korean researchers developed a process that enables the use of aluminum-doped zinc oxide film in radiation-resistant quartz glass. A demonstration in III-V solar photovoltaic space modules showed that the shielding effect of bare quartz glass was significantly improved. December 12, 2025 Valerie Thompson A South Korean research team led by the Korea Electronic Technology Institute (KETI) reported that quartz glass with a thermally annealed aluminum-doped zinc oxide film can provide electron beam protection for III-V space photovoltaic modules. “Our work shows that aluminum-doped zinc oxide (AZO)-coated quartz glass can serve as an effective radiation-shielding cover glass for space photovoltaic…
