6 FAQs about [General failure of solar power generation]

Does failure affect 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.

What causes a solar PV system to fail?

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.

What happens if a fault occurs in a solar PV system?

Reduced real time power generation and reduced life span of the solar PV system are the results if the fault in solar PV system is found undetected. Therefore, it is mandatory to identify and locate the type of fault occurring in a solar PV system.

Why does a solar PV system lose power?

In addition, the efficiency drop in a solar PV system is because of the effect of various kinds of faults and failures, which the system suffers. According to the test results conducted in 2010, the annual power loss in the solar PV system is about 18.9% due to its faults and failures .

How to identify the severity of failure modes in solar 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.

Are there failure probabilities in solar PV system components?

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).
