Dear all,
I am trying to simulate a solar PV plant with type 94a in different cities around the world. As known, the efficiency of a pv module, decrease with the increasing of the ambient temperature. It seems that the component doesn't take properly into account this behaviour. In fact, for example, I find a bigger average annual efficiency of solar field in Ryiadh than in Napoli. I have also noticed that the changing of the value of the parameter n. 8 (=Temperature coeficient of Voc (ref. cond.)) does not produce any change in the output power.
Do you know what is the reason for these inconsistencies? Where I can finde the source code for this type to check the equation used for the calculation (I don't find it in my installation path)?
Thanks in advance for your help.
Best Regards,
Marco Scarpellino
