Parameter estimation of double diode photo-voltaic module

Abstract

Solar Energy is a clean and boundless energy source and the worldwide solar market demand is increasing for industrial and domestic purposes. The purpose of this paper is to show the comparison of Stochastic Method(Genetic Algorithm) over derivative methods. A mathematical development [3] is provided for the extraction of Solar Panel equivalent circuit parameters from datasheet values. The analytical approach is selected for the mathematical development as the initial-point vital for proper evaluation of the Parameters of the double diode Model of PV cells. And thus using Evolutionary technique to extract the values of the parameters, a valid comparison has been presented between the numerical approaches and the Evolutionary Algorithms.
