This paper conducts a state-of-the-art literature review to examine PV failures, their types, and their root causes based on the components of PV modules (from protective glass to junction box). . With the global increase in the deployment of photovoltaic (PV) modules in recent years, the need to explore and understand their reported failure mechanisms has become crucial. The study analyzed three common PV technologies: thin-film, monocrystalline silicon, and polycrystalline silicon. The target audience of these PVFSs are PV planners, installers, investors, independent experts. . A photovoltaic (PV) module, commonly known as a solar panel, is composed of multiple layers. Failure of the backsheet allows humid air to enter the module, resulting in water. . This paper reviews recent progress in fault detection, reliability analysis, and predictive maintenance methods for grid-connected solar photovoltaic (PV) systems.
