Hello,

In your FAQ post titled "Why is the Pmpp of my module different than the specified value ?", you discuss differences between manufacturer specified nameplate Pnom and the Imp*Vmp result that PVSyst uses and why this happens. My question is, which value does PVSyst actually use throughout the simulation? If the single-diode model Pnom at STC is higher than nameplate Pnom of the module by a certain percentage, will the simulation output be higher by roughly the same percentage?

Thank you.

The simulation always uses the one-diode model, but at any irradiance and temperature conditions.
The effectve Pmpp at STC (or nominal efficiency) is never used as such. The model doesn't rely to any "nominal" efficiency value.
