pvpl Posted May 20, 2022 Share Posted May 20, 2022 In the help file I read: "When possible, the PV efficiency is calculated according to the operating conditions of the module. Otherwise it is taken as 10%. " In the hidden parameters I find that the 10% has been changed to 15%, but the real question is: what does it mean "when possible"?

André Mermoud Posted May 23, 2022 Share Posted May 23, 2022 The PV efficiency may be used in several different situations within PVsyst. - When used in the simulation, the Array temperature is known (evaluated from Tamb and GlobInc, by iteration). - In other situations (tool for PV curves or PV model plots, other tools outside of the simulation, this is not known and we have to do an hypothesis.
