Difference between GlobEff & GlobIAM

[bertin]

Hi there,

In the PVsyst 6 Help, I can find :

- GlobIAM : Global on collectors, corrected for horizon, near shadings and IAM

- GlobEff : "Effective" global, corrected for IAM and shadings simultaneously

I don't get the difference between those two variables?

Thanks in advance for your help

These values are the same if you don't specify Soiling losses.

The soiling losses will also be taken into account in the GlobEff value (it is the effective irradiance in the PV modules).
