Constructing Suns-Voc from Outdoor Time-Series I-V Curves
Description
Suns-Voc (or Isc-Voc) curves can provide the current-voltage (I-V) characteristics of the
diode of photovoltaic cells without the effect of series resistance.
Here, Suns-Voc curves can be constructed with outdoor time-series I-V
curves [1,2,3] of full-size photovoltaic (PV) modules instead of having to be measured in the lab.
Time series of four different power loss modes can be calculated based on obtained Isc-Voc curves.
