ALTERNATIVE METHODS FOR POTENTIAL INDUCED DEGRADATION EVALUATION IN PHOTOVOLTAIC MODULES

Abstract

This article addresses the investigation of alternative methods for evaluating Potential Induced Degradation (PID) in photovoltaic (PV) modules. Although PV modules are widely used in electricity generation, they are susceptible to various failure mechanisms, with PID being a notable one. Traditionally, PID detection is performed through electroluminescence analysis in a laboratory, involving the relocation of panels and additional costs. The identified methods aim to enable field evaluation, reducing both the costs involved and the losses in energy generation. This approach not only simplifies the detection process but also allows for a more prompt intervention to mitigate the detrimental effects of PID on PV systems.
