Dear André I'm designing a stand alone PV system with batteries. I simulated the system and obtained extranges results (or at least I can't understand them) as PR>1 or missing energy equal 0 when the PV system produce less energy than load requirement. (see attachment) Could you help me to know what is wrong? Thank you very much

Thank you very much André.

Good morning. I would like to know whats is the right wat to to calculate the yearly time series for the produced energy of a PV generator during its life using as a base the yearly production obtained from PVsyst and assuming a module's average degradation over the time. have I to assume that the annual produced energy obtained from the PVsyst simulation is the production for the first year?, and from it, i have to derate the power production for the following years with the panels degradation factor (0,5-1%)? Thanks you for your help, best regards Pablo
