Example Solar PV Array Curves
Displaying Diminishing Solar Light Intensity
Current-Voltage and Power-Voltage curves for a PV array containing six generic 180 Watt
PV panels in series.
Each panel having the following values at standard test conditions (STC of 1000 W/m
25 °C panel temp): Isc = 5.0 A, Voc = 50 Vdc, Imp = 4.6 A, Vmp = 40 Vdc
Curves calculated for five different light levels: 200 to 1000 W/m
constant 25 oC panel temperature
