Annual average capacity factor from the National Renewable Energy Laboratory (NREL).

Daily total solar direct normal irradiance average from 1998 to 2014 from the National Renewable Energy Laboratory (NREL).

Average daily total solar global horizontal irradiance average from 1998 to 2014 from the National Renewable Energy Laboratory (NREL).

Monthly average and annual average daily total solar resource averaged over surface cells of 0.1 degrees in both latitude and longitude, or about 10 km in size. The insolation values represent the resource available to fixed flat plate system tilted towards the equator at an angle equal to the latitude. The data are created using the SUNY Satellite Solar Radiation model (Perez, et.al., 2002).

Monthly average and annual average daily total solar resource (DNI) averaged over surface cells of 0.1 degrees in both latitude and longitude, or about 10 km in size. The insolation values represent the resource available to concentrating systems that track the sun throughout the day. The data are created using the SUNY Satellite Solar Radiation model (Perez, et.al., 2002). The data are averaged from hourly model output over 8 years (1998-2009).
