Abstract

The ability to reproduce electrical characteristics of a PV module is an essential skill for circuitoriented simulation of solar power processing equipment. This work presents and compares selected PV parameter estimation techniques. The five parameters of the single diode equivalent PV circuit, namely series resistance, shunt resistance, photo-generated current, diode ideality factor and saturation current are estimated according to analytical methods involving the Lambert-W function and numerical methods using the Newton-Raphson algorithm. For each method, current vs. voltage and power vs. voltage curves are generated and compared with the graphs reported in the datasheet. It is observed that curves obtained by extracting the five parameters via analytical solutions are closer to the characteristics published by the manufacturer than those curves obtained by extracting the parameters via numerical methods. Based on this evidence and also considering the ease of implementation, analytical parameter estimation techniques are preferred to their numerical counterparts for PV modelling within circuit based simulation environments.
