NREL: India Solar Resource Maps

India Solar Resource Maps

This page contains high-resolution solar resource maps and data for India. The high-resolution (10-km) solar resource data were developed using weather satellite data incorporated into a site-time specific solar mapping approach developed at the U.S. State University of New York at Albany. The data were output as data in geographic information system (GIS) format and as static maps.

These products were developed by the U.S. National Renewable Energy Laboratory (NREL) in cooperation with India’s Ministry of New and Renewable Energy, through funding from the U.S. Department of Energy.
