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.Energy storage systems (ESS) addressed in Article 706 will have different currents, as will standalone PV systems in Article 710. Adapting the Code to PV Currents. When the irradiance is greater than the STC value, we get a PV system that can produce more power (voltage and current) than its rated values at STC.
