If faults in any components (modules, connection lines, converters, inverters, etc.) of photovoltaic (PV) systems (stand-alone, grid-connected, or hybrid PV systems) are not detected and corrected quickly, they can have a significant impact on the efficiency, energy yield, as well as the security and reliability of the entire PV plant. Furthermore, some defects (such as arc faults, ground faults, and line-to-line faults) might contribute to the danger of fire. Fault detection and diagnostic (FDD) technologies are critical for PV plant system dependability, high efficiency operation, and safety. The kinds and causes of PV system failures are described in this study, followed by a review and discussion of several approaches offered in the literature for FDD of PVS, with a focus on faults occurring in PV arrays (PVA). Methods that can accurately identify, locate, and categorize potential defects in a PVA are given special consideration. The merits and limitations of FDD techniques for large-scale integration are discussed in terms of practicality, complexity, cost-effectiveness, and generalization capabilities. Challenges and ideas for future research directions are also offered based on the evaluated publications.
