China launches 250 MW hybrid fishery-solar farm with 370,000 panels

China has launched one of the world’s largest hybrid fishery-solar farms in Tangshan, Hebei Province, developed by Beijing-based Dajin Heavy Industry. The project integrates a 250 MW solar photovoltaic (PV) farm with aquaculture, covering approximately 353 hectares. It features 370,000 bifacial solar panels installed above fish ponds, which capture sunlight from both sides—benefiting from the water’s reflective surface to enhance energy generation. The farm is expected to produce around 400 million kilowatt-hours of clean electricity annually, saving 120,000 tons of coal and reducing carbon dioxide emissions by 320,000 tons, thus contributing to improved local air quality. This fishery-solar hybrid model offers multiple advantages beyond energy production. The solar panels provide shade that lowers water temperatures, improving aquatic life metabolism and reducing disease outbreaks in fish. Additionally, the shade decreases water evaporation, conserving water resources. The cooling effect of the water also increases solar panel efficiency by up to 15%
