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.
It’s also possible that one solar panel in your pv array failed. As the pv modules are connected in series, one failing pv module will shut down the entire system. If your solar system is not delivering sufficient power for which it is rated for, the resulting situation is called a low power situation.
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.
Please note: The most common fault on a Solar PV System is the Inverter Failing internally on a hot sunny day. Every type of Solar PV system that you will come across works on the same main principals: Solar Irradiance (sunlight) shines onto the panels (Photovoltaic Cells) which starts generating an electrical current.
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.
These two conditions which may require troubleshooting are: Zero output is a common problem and in nine out of ten cases, it is due to a faulty inverter or charge controller. It’s also possible that one solar panel in your pv array failed. As the pv modules are connected in series, one failing pv module will shut down the entire system.
