China has announced that the largest floating photovoltaic (PV) facility on earth has finally been completed and connected to the local power grid. Long reviled for its carbon emission record, this is the Chinese government’s latest achievement in its ongoing effort to lead the world in renewable energy adoption.
Located in the city of Huainan in the Anhui province, the 40-megawatt facility was created by PV inverter manufacturer Sungrow Power Supply Co. Ironically, the floating grid itself was constructed over a flooded former coal-mining region.
Floating solar farms are becoming increasingly popular around the world because their unique design addresses multiple efficiency and city planning issues. These floating apparatuses free up land in more populated areas and also reduce water evaporation. The cooler air at the surface also helps to minimize the risk of solar cell performance atrophy, which is often related to long-term exposure to warmer temperatures.
This is just the first of many solar energy operations popping up around China. In 2016, the country unveiled a similar 20MW floating facility in the same area. China is also home to the Longyangxia Dam Solar Park, a massive 10-square-mile, land-based facility touted as the largest solar power plant on earth.
