This paper reviewed several publications which studied the failures of the PV power plant equipment's and presented that the central inverter failures rate is the highest for the PV power plant equipment's which affected negatively in both PV power plant availability and ROI.
As discussed in, , , , Some authors use the machine learning software to estimate the common failures of the PV inverters by collecting large numbers of maintenance records and implement the data analysis. Table 3 shows frequently O&M Tickets for PV Inverter Failures as per O&M tickets based on field data gathering.
Some authors discuss inverter failures due to the issues of reactive power control. The PV inverters operate at unity power factor, but as per the new grid requirements, the PV inverters must operate at non unity power factor by absorbing or supplying reactive power to control the grid voltage and frequency.
The general PV system consists of subsystems that decompose to subassemblies as shown in Fig. 4 . The central inverters failure rate is the highest for the PV power plant components. It is estimated that 52% to 60% of the total failures rates of overall equipment of the PV power plant as shown in Fig. 5 .
