Solar irradiation databases from satellite estimates are based on images taken from satellites with wide spatial resolution. The rising interest on solar energy technologies and climate change suppose the necessity of high spatial resolution data of solar irradiation. The downscaling of satellite estimates provides an alternative to dense pyranometers networks, which are very expensive to maintain. The methodology proposed is based on the shade impact analysed from a digital elevation model of high spatial resolution. This methodology is applied and validated with on-ground measurements in the Iregua river valley in the Spanish region of La Rioja. Eventually, it is generated a map of the annual sum of solar global irradiation for this valley
