Parameters Determination of PV Cell Using Computation Methods

Abstract

This paper describes two algorithms Newton's algorithm and Improved Newton-Horner algorithm for solving non-linear equation of an electrical circuit of a PV cell. In these algorithms, an approximated solution is assumed; then the assumed solution is used to construct the electrical parameters of a solar cell. The proposed method consists for solving the solar cell's equation using the initial value x0=1. Moreover, the Newton's and Improved Newton-Horner algorithms are used to determine the required voltage,current, and power of the PV cell according to different values of 푅퐿have introduced with the aid of Matlab language. The obtained results appeared that the suggested technique is the most effective compare with NRM
