Summary

This layer contains the GHI solar power potential within the contiguous US and Hawaii. This polygon file is intended for small scale thematic mapping.

Description

            

The spatial data were obtained from the National Renewable Energy Laboratory and are current as of 2012. The layer is composed of 10km resolution grid cells, each with a GHI value. The attributes were modified to include gridcode annual GHI value, and monthly GHI values. The coordinate system of this data is WGS 1984.

“GHI, which stands for Global Horizontal Irradiance, is the total amount of shortwave radiation received from above by a surface horizontal to the ground. This data provides 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. This data was developed using the State University of New York/Albany satellite radiation model. This model was developed by Dr. Richard Perez and collaborators at the National Renewable Energy Laboratory and other universities for the U.S. Department of Energy.” - NREL
