Consider a crystalline PV module with the following output parameters mentioned at STC (Standard Test Conditions) conditions by the manufacturer.
Pmax = 300 W
Voc = 40 V
Isc = 8 A
NOCT = 40°C
Temperature coefficient of power = -2 W/°C
If the ambient temperature falls to 15°C while the irradiance is 1000 W/m², what is the cell level temperature in ºC, as per the NOCT model?
