MITIGATING POTENTIAL-INDUCED DEGRADATION (PID) IN SOLAR PANELS THROUGH GROUNDING: DIAGNOSTIC AND OPTIMIZATION APPROACHES

Abstract

Annotation; This paper explores diagnostic and optimization approaches to mitigate Potential-Induced Degradation (PID) in photovoltaic (PV) modules through effective grounding techniques. PID is a critical issue in solar energy systems that leads to significant power losses due to high-voltage stress and leakage currents. The study analyzes the underlying mechanisms of PID, evaluates common diagnostic tools used for early detection, and examines various grounding strategies to reduce or eliminate its effects. Experimental results and comparative assessments highlight the effectiveness of isovalent impurity doping and optimized grounding configurations. The findings offer practical insights for improving the long-term performance and reliability of solar panels in high-voltage applications.
