[TRNSYS-users] PV simulation

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
