NREL: News - NREL data set shows clouds' effects on solar power: via @AddThis

News Release NR-4411 NREL data set shows clouds' effects on solar power Measurement stations in Hawaii gauge second-by-second impact August 31, 2011 The U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL)has produced and made available a rich data set showing what happens, second-by-second, when clouds pass over a solar power installation. Seventeen measurement stations near Hawaii’s Honolulu International Airport on the island of Oahu collected data at 1-second intervals over the course of a year. The data set is of great interest to utilities, developers of large-scale photovoltaic (PV) systems, forecasters, system operators, laboratories and universities. By understanding the characteristics of cloud shadows that pass across a large PV system, utility officials can devise strategies to better manage those fluctuations so the grid isn’t adversel...
