GIS-based solutions have been proposed to estimate incoming solar radiation. This research investigated the dependence of estimation solar radiation from DEMs on two basic elements of the estimation: (1) the spatial resolution of DEM and (2) GIS-based models, specifically how it defines climate and terrain parameters. Three models (SRAD, r.SUN, and ESRI) for estimating incoming solar flux were implemented in different platforms (i.e., C++ and FORTRAN, GRASS, and ArcGIS), respectively.
