Diffuse irradiance mode

[ClaireWest]

When i provide GHI as input but not DHI (so PVsyst has to calculate DHI), why does the PVsyst output report say "Diffuse: Perez, Meteonorm" under "Models used" when the PVsyst advice on this is that the Erbs model is used and Perez is not currently implemented?

It is correct, that PVsyst uses the Erbs correlation for the case that only GlobHor (GHI) is given, and the diffuse contribution needs to be derived from a model.

The report does not seem to reflect this properly. A ticket has been created to fix the problem in one of the next PVsyst releases.

Thank you for reporting the issue.
