Abstract

The potential induced degradation (PID) phenomenon of crystalline silicon photovoltaic (PV) modules has been often found in outdoor PV systems until recently since firstly reported in 2010. Many studies have been conducted about the mechanism and the preventive methods, but systematic diagnosis of the PID has not been applied on-site. This paper focuses on analysis of 5 categories and 10 PID diagnosis methods using the monitoring data, light current-voltage, dark current-voltage, infrared and electroluminescence. We expect to contribute to improvement of power generation through PID diagnosis and troubleshooting in PV plants.
