6 FAQs about [Solar power generation shows transformer failure]

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.

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.

What are the challenges of a PV plant distribution transformer?

Other challenges include voltage transients (switching, voltage dips and swells), caused by non-linear loads . These transients can result in abnormal stresses in the insulation of the transformer. PV plant distribution transformers are also energised and de-energised more frequently, often daily .
