Solar potential Monthly totals

Solar potential Monthly sums based on calculations of the radiation model STRAHLGRID of GeoSphere Austria. It takes into account different components of solar radiation (such as direct and diffuse radiation) on any inclined surfaces. Effects such as cloudiness of the atmosphere due to water vapour and aerosols, cloudiness, shading through the horizon as well as terrain and multiple reflections (e.g. snow) are also taken into account.
