Photovoltaic (PV) solar energy is one of the most critical renewable energy sources, which has grown worldwide in the last decade. PV markets are becoming highly competitive and increasing the need for research and development in efficiency and reliability optimization, maintenance and diagnostics of key components such as PV modules. It is becoming of particular interest to current PV plant operators, maintenance engineers future investors and the research and development sector of the PV industry. This study presents an analysis and a hands-on review of detected faults in PV modules with infrared thermal (IRT) diagnostics, which are becoming increasingly popular in the field. In the present study, the causes and types of faults were analyzed by performing thermal imaging in solar power plants (SPPs) in Turkey. According to the flight tests, it has been determined from the results obtained from the SPP in Turkey that the connection fault problem, cracked broken panels, broken bypass diodes, shading and exploded fuse affect the panels significantly and have an important efficiency regarding production. Improvements in energy production in SPP are possible when the technical connection fault in the field is resolved. In particular, in the first main part of this study, the characteristics of the most common fault types of PV modules were reviewed and the PV system, PV module efficiency, and system configuration were explained and information about the thermal drone and flight information used, SPP was provided. Then, the second part discussed of the results of detected faults in field areas with IRT-based diagnostics and thermal image processing, tracked by a discussion of the future prospects, recommendations and challenges for understanding and diagnosing faults.
