Abstract: There are many reasons for the output degradation of the PV module. The main factors are the higher PV module temperature, the shaded cell or module, the shortened or conducting bypass diodes, the PV array is soiled, degraded and so on. In this study, we have studied the operation method of thermal imaging camera to analyze the degree of deterioration of PV module. The modeling of photovoltaic cells and the principle of generating hotspot were studied and the thermal changes were studied by electrical analysis. In addition, an experiment was performed to analyze the thermal change of PV module using a thermal imaging camera and to predict the deterioration state of the PV module.
