The US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) has released an updated 20-year version of its US National Solar Radiation Database.
The web-based report covers a period between 1991 and 2010, including, for the first time, data from 2006 to 2010. It holds information about solar and meteorological data for 1,454 locations in the US and its territories. It also provides improved cloud algorithms for modelling solar radiation data and a State University of New York model for gridded data based on satellite observations.
The updated project was completed in partnership with Clean Power Research and the National Climate Data Centre.
