With the widespread adoption of solar photovoltaic (PV) systems, ensuring their efficient and stable operation is essential. However, during long-term operation, PV systems may encounter common faults.
Current methodologies can be divided into two categories: The first one identifies photovoltaic (PV) defects, whereas the second one categorizes the specific sort of fault in a photovoltaic (PV) system. The literature has proposed various suggestions for fault identification.
Therefore, detecting and identifying faults in PV systems is an essential task that helps to improve the reliability, efficiency and safety of PV systems. Without suitable and proper detection, the emergence of faults in PV power plants causes performance losses and can lead to safety issues and fire hazards.
Therefore, PV system (PVS) fault diagnoses are crucial for PV power plant reliability, efficiency, and safety. Many fault diagnosis methods and techniques for PVS components have been developed. In addition, with the development of PV devices, more advanced and intelligent diagnostic technologies are continuously being researched and developed.
For a number of years, in an effort to improve photovoltaic systems'' performance, research on the technology has focused on fault analysis, installation reliability and system degradation. The
