The module estimates the spatial distribution of irradiance value (W/mq) in a specific area that has elements of complexity, e.g. inhomogeneous morphology of the terrain, buildings, vegetation. The input elements are the terrain surface and building models which can be added by the user via a specific user interface. The module surveys the earth surface and creates three representations of irradiance: (i) on bare ground, (ii) on roofs and (iii) on both. These analytical surfaces are calculated using a model which considers the angle of incidence, atmospheric factors, and other items that are entered at the user level.
