[Stand alone project extrange simulation results]

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.

[Hw to calculate yearly time series of produced energy for a PV generator]

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
