 We investigated the possibility of estimating global horizontal irradiance, GHI, and parallel to photovoltaic, PV, power production in India using a radiative transfer model, RTM, called Liberatran Fed with satellite information on the cloud and aerosol conditions. For the assessment of PV energy production, we exploited one year's January-December 2018 ground-based real-time measurements of solar irradiation GHI via silicon irradiance sensors, C-sensor, along with cloud optical thickness, COT. The data used in this method was taken from two different sources, which are UMITSAT's MediaSAT Second Generation, MSG, and aerosol optical depth, AOD, from Copernicus Atmospheric Monitoring Services, CAMS. The COT and AOD are used as the main input parameters to the RTM along with other ones, such as solar zenith angle, angstrom exponent, single scattering albedo, etc., in order to simulate the GHI under all sky, clear, no clouds, and clear clean, no clouds and no aerosols, conditions.
