In PV*SOL® you are able to analyse the additional yield due to bifacial modules. There are two ways to activate the calculation of bifacial modules:
If you create a module elevation in 3D planing that contains a PV module whose bifacial factor is greater than 1, the system is automatically calculated as bifacial. The necessary data such as frame distance, height, etc. are taken directly from the 3D model. On the overview page of the 3D system, the data can be viewed in the “Elevation for bifacial modules” dialog.
If you create a PV system without using 3D planning, the calculation of bifacial modules is activated simply by selecting a bifacial module and the installation situation “Mounted - roof” or “Mounted - open space”. If neither of the two installation situations is selected, a corresponding message appears.
An important value for the calculation of the radiation on the rear side of the module is the reflectivity of the substrate, the albedo. The Albedo can be set in the project options (see also PV modules > Further parameters).
