GlobEff and GlobInc

[dtarin]

Hello,

I am aware of what the differences are between GlobEff and GlobInc as stated in the PVsyst documentation. What I would like to know is if one of these is better suited for evaluating plant performance depending on the irradiance sensor used, such as a pyranometer or Si reference cell? And perhaps not just GlobEff, but the other corrected incident energy parameters as well. What would be a physical or practical application of these parameters?

Thanks.

The simulation is suited for using pyranometer measurements.

Reference cells may be used for the evaluation of the stability of the PR, but suffer of IAM and spectral discrepancies. You also have to check the ageing of the reference cell (like the Pyranometers, which should be recalibrated form time to time).
