<Dl> <Dd> In May 2008, the Far Niente Winery in Oakville, CA pioneered the world's first "floatovoltaic" system by installing 994 photovoltaic solar panels onto 130 pontoons and floating them on the winery's irrigation pond . The floating system generates about 477 kW of peak output and when combined with an array of cells located adjacent to the pond is able to fully offset the winery's electricity consumption . The primary benefit of a floatovoltaic system is that it avoids the need to sacrifice valuable land area that could be used for another purpose . In the case of the Far Niente Winery, the floating system saved three - quarters of an acre that would have been required for a land - based system . That land area can instead be used for agriculture . Another benefit of a floatovoltaic system is that the panels are kept at a lower temperature than they would be on land, leading to a higher efficiency of solar energy conversion . The floating panels also reduce the amount of water lost through evaporation and inhibit the growth of algae . </Dd> </Dl> <Dd> In May 2008, the Far Niente Winery in Oakville, CA pioneered the world's first "floatovoltaic" system by installing 994 photovoltaic solar panels onto 130 pontoons and floating them on the winery's irrigation pond .
