Abstract

This paper simulates the effects of photovoltaic (PV) module temperature variations on the different characteristic of PV array with MATLAB/Simulink software. Four classification for temperature variations of PV module have been defined that are soft uniform, hard uniform, soft nonuniform and hard nonuniform temperature variations. The changes of five parameters of the PV array that are maximum output power (MOP), open circuit voltage (VOC), short circuit current (ISC), fill factor (F.F.) and efficiency have been investigated under four temperature classification. The results are shown that in the two first classes and different scenarios in each class, the MOP, VOC, F.F. and efficiency are monotonically increasing with decreasing the uniform temperature while the ISC of PV array decreases with decreasing the uniform temperature. For nonuniform temperature variations, the MOP, VOC and efficiency have reverse relationship with temperature variations but for two other parameters ISC and F.F., there is not any direct relationship. Also for all classes, always the relationship of five parameters with temperature variations is nonlinear.
