The risk priority analysis is considered one of the promising approaches for identifying the severity of failure modes. The study reports shows that the inverter and ground system has a failure mode with high RPN. Table 1 summarizes various faults related to solar PV systems as reported in the literature studied. Table 1.
The hotspot failure mechanism is considered the most severe failure and leads to catastrophic consequences. It deteriorates all PV module components if undetected, and a PV module affected by an elevated level of hotspots cannot reverse the degradation and often requires replacement.
The PV module failure modes that stood out as the most relevant include PID (50), shading (24), bypass diode failure (24) and junction box overheat-ing (24). Figure 2 presents a chart depicting these failure modes in the PV module with the highest RPN, which helps visualize and highlight the criti-cal failure modes.
The main degradation and failure modes of PV encapsulants include discolouration and delamination, such as in Fig. 5. Additionally, encapsulants are often partly responsible for degradation of other module components by facilitating or mediating degradation modes such as corrosion or potential induced degradation (PID) [25, 61, 104, 114, 115].
The failure of the components affects the reliability of solar PV systems. The published research on the FMEA of PV systems focuses on limited PV module faults, line-line contact faults, string faults, inverter faults, etc. The literature shows that the reliability analysis method is used to evaluate different faults in PV systems.
To reduce the degradation, it is imperative to know the degradation and failure phenomena. This review article has been prepared to present an overview of the state-of-the-art knowledge on the reliability of PV modules.
