Landsat and MODIS satellite image processing for solar irradiance estimation in the department of Narino-Colombia

The identification of solar potentials in remote areas represents an opportunity to provide renewable energy solutions to population isolated from the main electric grid. For this, a methodology to estimate the solar irradiation is proposed, taking into account free satellite images from Landsat 7 and MODIS projects. The method includes the image processing and regression models to obtain high-resolution solar irradiance maps. To prove the application of the methodology, the process is performed over a zone in Southwest Colombia and the resulting maps are presented in a website with georeferencing tools.
