Degradation analysis of PV modules operating in Australian environment

Degradation analysis is important in photovoltaic (PV) modules to monitor the performance of the PV system. In this paper, PV module degradation analysis is performed in the Australian environment. The method uses short circuit current evaluation of the PV modules in experimental setup. Through versatile experiments on a number of modules, it is found that degradation results in an increase in series resistance and decrease in module currents. The reduction in module current may lead to loss of generated power and further accelerated degradation
