Huasun supplies HJT modules for Shandong agrivoltaic plant: In a WeChat communication, leading heterojunction (HJT) module manufacturer Huasun said that a 100 MW agrivoltaic power plant to which it had supplied its Himalaya G12 HJT bifacial dual-glass modules for the project has been successfully connected to the grid. Located in in Gaomi, Shandong Province, the plant combines photovoltaic power generation with agricultural cultivation beneath the modules, targeting an average annual output of 140 million kWh. These modules feature advanced encapsulation techniques and new light conversion films, ensuring excellent waterproofing and resistance to humidity and heat. The modules also deliver strong performance in weak light conditions such as rain, dawn, or dusk, maximizing the utilization of sunlight over agricultural land, the company added. At Intersolar Europe this year, Huasun Energy stood out with its innovations designed to address both current market pressures and long-term technology shifts (see Vertical PV And Pre-commercial Tandem Modules From Huasun)
CNNP Optoelectronics commissions 200 MW perovskite production line: CNNP Optoelectronics, a subsidiary of China National Nuclear Corporation (CNNC) specializing in perovskite research and manufacturing, has signed a 100 MW perovskite module supply agreement with China National Nuclear Corporation (CNNC) New Energy, officially commissioning a fully automated 200 MW rigid perovskite mass production line technology development and scenario-based application verification.
