Hanersun releases 695 W TOPCon solar module with 22.37% efficiency rating
China’s Hanersun has unveiled its HItouch 6N module series, which is based on n-type TOPCon tech, 210 mm wafers, and half-cut cells. The monofacial and bifacial modules feature power outputs ranging from 605 W to 695 W and efficiency ratings of 21.38% to 22.37%.
Giant battery goes online in China
Sineng Electric has switched on a 400 MW/800 MWh storage facility in China’s Shandong province. The project features the company’s 3.15 MW turnkey battery stations.
New electrolyzer to split saltwater into hydrogen
Chinese scientists have developed a new way to split seawater into hydrogen without using a separate desalination process. They incorporated a self-breathable waterproof membrane and a self-dampening electrolyte (SDE) into the electrolyzer, so water migrates from the seawater across the membrane to the SDE, without extra energy consumption.
Construction begins on massive solar-plus-storage project in China
China’s Three Gorges New Energy has started building the first 1 GW phase of solar-plus-storage capacity for a planned 16 GW mega-project in Inner Mongolia’s Kubuqi Desert. Upon completion, the massive installation will include 8 GW of solar, 4 GW of wind, and 4 GW of upgraded coal capacity.
Tibet commissions 120 MW, high-altitude solar plant
China Huadian has connected a 120 MW solar plant to the grid in the Tibetan city of Nagqu, which has an average altitude of 4,500 meters. The installation is reportedly the largest PV project in Tibet.
