Abstract
Numerous sources provide methods to extract photovoltaic (PV) parameters from PV module datasheet values. The inputs are the number of series cells N-s, open circuit voltage V-oc, maximum power voltage Vmp, maximum power current Imp, and short circuit current Isc. The 5 Parameter Model solutions outputs are diode ideality factor ?, series resistance Rs, parallel resistance R-p, photon light current I-L, and diode reverse saturation current I-o. The parameter solution requires solving three simultaneous transcen-dental equations for ?, R-s, and R-p and additional calculations for I-L and I-o. One of the primary tenants of Systems Engineering, verification, was applied to parameter solution results to check for physical and model fitness. This manuscript provides novel methods to verify parameter results and applies them to available solutions.
