The dc currents produced by PV modules vary directly with sunlight intensity and when the irradiance exceeds 1000 W/m2, the currents may exceed the Standard Test Conditions (STC) rated values of Imp and Isc. The maximum current a module can deliver is Isc and the rated Isc is multiplied by a safety factor.
