Reduced–Form of the Photovoltaic Five–parameter Model for Efficient Computation of Parameters

"This brief note presents a reduced–form of the five–parameter model introduced. by Desoto et al. (2006) and subsequently generalized by Tian et al.. (2012). The five–parameter model computes five reference parameters utilized. to synthesize performance curves in photovoltaic panels from information. available in datasheets. The improvement resulting from the reduced–. form is two–fold: (i ) the model is reduced from five to two parameters and. (ii ) as a result of (i ) a domain of attraction of the solution space is defined. analytically, which guarantees nonlinear solvers will provide the correct, that. is, physically feasible, solution for the parameters at first launch.
