Modeling the PV generator is the second step in the simulation chain for photovoltaic systems. Finally, the electrical behavior of the PV module is simulated from the output data of the radiation modeling. The following sub-steps are necessary:
Various characteristic models are used in PV*SOL to determine the characteristic curves. The calculation of the current-voltage characteristics takes place at each time step in the simulation for each module. In the next step, the characteristic curves of the modules are superimposed in series or in parallel, depending on the wiring, in order to determine the characteristic curve of the PV field.
Input parameters are shown in green, intermediate variables in gray and the models that take over the actual calculation in yellow. Blue stands for simple operations such as addition, subtraction or trigonometric calculations.
