Why do I get differences in yield in the simulation of different modules, although they have the same power and similar characteristics?

Usually the reason for that is the part load operation behavior of the modules. The specific data for every module are entered in the database by the manufacturers. They have the possibility to enter a specific part load operation point for their modules in our database. Then a specific part load operation curve is calculated for the module. If the manufacturer don’t enter the specific part load operation point and select the "standard part load operation" option a curve for the cell type is used (e.g. monocrystalline) for the calculation. Which part load operation curve is used for the selected modules can be seen in the database.
