tecnun Posted February 18, 2021 Share Posted February 18, 2021 Hello André and Team,Simulating a PV Plant with our Client .pan file (defined parameters by 3rd Party tests) we realized there was a problem with Rs definition. I´m attaching warning of too high Rs definition, so we made a simple test: We created a new module definition with half Rs value (0,059 instead 0,118) and we surprised that simulation yield was similar even a little bit worse.As we know if Rs decreases, gamma increases, I-V curve "flatten" and module power decreases, at least in our understanding (please correct me if I am wrong). Is it PVsyst model correct??It is charted in your tool (you can see it also at the images we attach) that changes are minor indeed, yes in this case a little bit better shape factor with Rs = 0,059 (half Rs), but a minor difference (but gamma now is higher!)Is it something wrong with simulation and/or graphical tool? What am i missing?We hope this could be analyzed, best regards Link to comment Share on other sites More sharing options...
