How are thin-film modules calculated in your software?

All modules are calculated with the part-load characteristic curve (efficiency or ETA curve). The specific part load operation for the modules is in some cases given by the manufacturer (see "Databases" - "PV Module" - "U/I Char. – Part Load"). In all other cases a characteristic curve is used that is specific to the cell type. It is possible to select from 11 different cell types. For the 5 thin film types: amorph, HIT, CIS, CdTe and triple a-Si, standard characteristic curves are available for typical part load operation. For the other 6 cell types the standard operation for monocrystalline modules is used.
