The information on solar suitability is entered into database and presented in a series of GIS map layers. Our state-of-the-art GIS database of solar resource availability is in the process of constant growth and development, as information is constantly being added to our digital warehouse. Both empirical data and numeric models are used to achieve high-resolution estimates for all available energy sources. Resource maps are delivered to our customers in hardcopy as well as digitally in MapInfo or ArcView format.
