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 are the different types of solar PV faults?

The faults occurring in the solar PV system are classified as follows: physical, environmental, and electrical faults that are further classified into different types as described in this paper. Once a fault is located and detected, an appropriate diagnosis method needs to be used to rectify it.

Do PV systems have internal faults?

Other than environmental implications, PV systems are seen to encounter inner faults for example, ranging from basic electrical faults (open-short/circuit) to Power Processing Units (PPU) faults such as Maximum Power Point Tracker (MPPT), and inverter malfunction [9, 10].

Why do photovoltaic systems fail?

PhotoVoltaic (PV) systems are often subjected to operational faults which negatively affect their performance. Corresponding to different types and natures, such faults prevent the PV systems from achieving their nominal power output and attaining the required level of energy production.
