The aim of this study is the estimation of solar irradiance on building roofs in complex Alpine landscapes. Very high resolution
geometric models of the building roofs are generated by means of advanced automated image matching methods. Models are
combined with raster and vector data sources to estimate the incoming solar radiation hitting the roofs. The methodology takes into
account for atmospheric effects, site latitude and elevation, slope and aspect of the terrain as well as the effects of shadows cast by
surrounding buildings, chimneys, dormers, vegetation and terrain topography. An open source software solution has been developed
and applied to a study area located in a mountainous site and containing some 1250 residential, commercial and industrial buildings.
The method has been validated by data collected with a pyranometer and results made available through a prototype WebGIS
