Solar power potential mapping in India using remote sensing inputs and environmental parameter

The present paper maps the district-wise potential for concentrating solar power (CSP) and centralized solar photovoltaic (SPV) technology based power plants in India. The evaluation is based on remotelysensed annual average global horizontal irradiance (GHI) and direct normal irradiance (DNI) provided by National Aeronautics and Space Administration (NASA) surface meteorology and solar energy program.The solar irradiation data (GHI and DNI), land-use data and Digital Elevation Model (DEM) were used in GIS environment while employing land-use criteria and topography to exclude unsuitable sites for harnessing solar energy. Furthermore, land-cover factor, number of sunshine hours and conversion efficiencies were taken into account to calculate technical potential in suitable land areas for solar power development. The result shows potential sites for installation of CSP and centralized large scale SPV plants in India.?
