<Ul> <Li> Floating solar arrays </Li> </Ul> <Li> Floating solar arrays </Li> <Dl> <Dd> Floating solar arrays are PV systems that float on the surface of drinking water reservoirs, quarry lakes, irrigation canals or remediation and tailing ponds . A small number of such systems exist in France, India, Japan, South Korea, the United Kingdom, Singapore and the United States . The systems are said to have advantages over photovoltaics on land . The cost of land is more expensive, and there are fewer rules and regulations for structures built on bodies of water not used for recreation . Unlike most land - based solar plants, floating arrays can be unobtrusive because they are hidden from public view . They achieve higher efficiencies than PV panels on land, because water cools the panels . The panels have a special coating to prevent rust or corrosion . In May 2008, the Far Niente Winery in Oakville, California, pioneered the world's first floatovoltaic system by installing 994 solar PV modules with a total capacity of 477 kW onto 130 pontoons and floating them on the winery's irrigation pond . Utility - scale floating PV farms are starting to be built . Kyocera will develop the world's largest, a 13.4 MW farm on the reservoir above Yamakura Dam in Chiba Prefecture using 50,000 solar panels . Salt - water resistant floating farms are also being constructed for ocean use . The largest so far announced floatovoltaic project is a 350 MW power station in the Amazon region of Brazil . </Dd> </Dl> <Dd> Floating solar arrays are PV systems that float on the surface of drinking water reservoirs, quarry lakes, irrigation canals or remediation and tailing ponds .
