The largest floating photovoltaic (PV) solar power facility on earth has been connected to a local power grid in China. Located in the city of Huainan in the Anhui province, the 40-megawatt facility was created by PV inverter manufacturer Sungrow Power Supply. The lake supporting the facility was created by rain after the surrounding land subsided after intensive coal mining operations. Floating solar farms don’t take up valuable land in heavily populated areas, can reduce evaporation from reservoirs and the cooler air at the water’s surface helps to maximize cell performance.
