Dear PVsyst team,
I am working in some projects where I can see a high GlobInc gain using default Perez model.
Basically, the model is giving numbers higher than ClearSky model calculated by Nrel guidances (gain of transposition ~26%).
When using Hay model, the result is more than 1% lower than Perez model and the results (see the picture) raised an alert on that topic, once simulations we received from providers presented lower gain when compared to ours (maybe a local installation issue?).
I would like to confirm if the difference in the models are consistent and if Perez model in latest version is really reliable.
