Abstract：In this paper, a novel solution to the equivalent resistances of a photovoltaic (PV) cell was developed. The simulation model of a PV array is established using a matlab/s-function. In addition, popular MPPT algorithms for PV systems-perturb and observe algorithm (P&O) and incremental conductance algorithm (INC) are investigated. A modified P&O algorithm is proposed for the improvement of P&O algorithm. Both simulation results and experimental results demonstrate the validity of the model of PV array and the advantages of the proposed P&O MPPT algorithm.
