Module cell temperature

Dear André,

I would need to know if PVsyst calculates operating module cell temperature from the formula below.

or a more sophisticated formula deriving from NREL, link as below.

Hope to hear from you soon. Thank you in advance !

No. We consider that this NOCT approach is confusing, and not reliable in a system (doesn't take the installation mode into account, and concerns modules in open circuit).

PVsyst uses an energy balance, which is fully explained in the help "Project design > Array and system losses > Array Thermal losses".
