A simplified and accurate photovoltaic module parameters extraction approach using matlab

This paper presents a novel approach to extract accurately the photovoltaic (PV) module single-diode model five parameters I_ph, I_sat, A, R_s, and R_p. The parameters extraction method incorporated a new equation dP/dI=0 at the maximum power point replacing the typically used equation in the literature dI/dV=-1/R_p. The new equation avoids the dependence on the value of R_p, and it also does not require any complex calculation and tedious combination of other equations to extract the five parameters for a PV module. The PV module behavior at different temperature and irradiance is also forecasted.
