A Holistic Study on Failures and Diagnosis Techniques in Photovoltaic Modules, Components and Systems

Abstract

The increasing adoption of photovoltaic (PV) systems worldwide highlights the need for reliable fault detection techniques to ensure optimal system performance. This paper presents a comprehensive analysis of various types of faults in PV systems, addressing all major types of physical, electrical and environmental faults of PV systems and their effects. The review also covers a wide range of fault detection methods proposed over the past decade for PV systems. The role and importance of a fault diagnosis technique in maintaining the smooth functioning and real-time energy production of PV systems is also highlighted. The work aims to provide researchers and professionals in the PV field with valuable benchmarks and updated information to improve fault detection and diagnosis techniques.
