Based on S-Function Builder of MATLAB/Sim-ulink,the established simulation model for photovoltaic(PV) modules utilizes C programming language to program the simplified mathematical model of PV modules,and then it is connected with other blocks in Simulink to simulate the performance of circuits. The outputs of the simulation model are compared with outdoor measured I-V curves of PV modules, the results of the comparison reveal good agreement with the greatest deviation of simulated maximum power only approxi-mately 1.8%,which shows the model is accurate enough for researches. In addition, the model of PV modules can be connected in series to form a PV array and simulate the output characteristic of PV array under partial shaded conditions.
