Artificial neural network based model for retrieval of the direct normal, diffuse horizontal and global horizontal irradiances using SEVIRI images

► Artificial neural network (ANN) ensemble based model for solar irradiance retrieval in a desert. ► Satellite thermal images as inputs provide beam and diffuse irradiance at 15min & 3km resolutions. ► The global horizontal irradiance is then computed from beam and diffuse irradiance estimates. ► Developed model could be used for near real-time beam, diffuse and global irradiance maps. ► Archived satellite images could be used to derive historical irradiation maps for past years.
