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.
Photovoltaic failure is not defined uniformly in the literature. Some definitions indicate that a drop of 80% in maximum output power is considered a PV failure . Others claim a 20% drop in maximal power is a PV failure . Durand and Bowling defined failure as a drop of more than 50% in maximum power output.
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 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.
Furthermore, some PV failures, such as cell cracks, propagate rapidly [33, 34]; if undetected, they will cause a significant cost loss that may reach up to 10 times the equipment cost . This is because some undetected failures may lead to fire and catastrophic damage to the entire PV system .
It is worth noting that most of the studies included in this review primarily focus on detailing failures and degradation observed in PV operations, which can be attributed to various factors, including the manufacturing process and other external influences.
