Back and front contact layers failure, failures of semiconductor layers, encapsulant failure. Faults related to string and central inverter. Errors in PV modules, cables, batteries, inverters, switching devices and protection devices are considered. The failure of the components affects the reliability of solar PV systems.
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.
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.
Several studies have discussed the issue of failure probabilities in solar PV system components (Abed and Mhalla, 2021;Ghaedi and Gorginpour, 2021;Ostovar et al., 2021;Shashavali and Sankar, 2021;Firouzi et al., 2022). (Table 5) lists the failure rates per unit hour of the PV-battery systems (Abdon et al., 2020).
The failure rate of photovoltaic system connected has been estimated based on , calculating the resulting failure rate based on each element of the PV installation element. For the calculation of precise reliability of PV farm, the number of panels should be considered, which in the analyzed installation is relatively large.
Critical observation of the junction box is required, and external factors that cause the panel to fail or degrade should be monitored carefully to prolong the panel’s life. Delamination and soiling are the solar panels’ most critical failure modes, having RPN values of 224 and 140, respectively, and contributing 16.2% to the total RPN.
