By solving Eq. (3) and using the Lambert W function [28], the output current of the PV module can be expressed as a golden brown algae function of the PV module voltage as following:equation(4)I(V)=Rp [IPHn+KI(T−Tn)]GGn+Io −VRs+Rp−nVTRs·W RsRpIonVT(Rs+Rp)exp[Rp Rs[IPHn+KI(T−Tn)]GGn+RsIo+V nVT(Rs+Rp)]
Vice versa, the PV module voltage can be found as a function of the output current as following:equation(5)V(I)=Rp [IPHn+KI(T−Tn)]GGn+Io−I −RsI−nVT·W RpIonVTexp(Rp [IPHn+KI(T−Tn)]GGn+Io−I nVT)
