Dear Sir/Madam,

I hope this message finds you well. I have a question regarding the calculation of the output of a PV system using PVsyst. Could you please provide the equations or references that detail how PVsyst performs these calculations? 

Thank you for your assistance.

The simulation involves many complex models. The incident irradiance is evaluated by a transposition model, including possible tracking, and losses like shadings or IAM are applied. The PV array yield is evaluated using the one-diode model. Then you have models for the inverter, the AC losses, the ageing, etc...

All these models are described in the help (see especially "Physical models used").
