This report describes data collection and analysis of solar photovoltaic (PV) equipment events, which consist of faults and failures that occur during the normal operation of a distributed PV system or PV power plant.

The paper presents failure rates per PV Site and per kW, considering all portfolio and dividing it regarding five PV plants groups per size, distribution of failures per element, Mean Time.

As of 2017, the inverter and associated power conditioning components accounted for $0.15/W– $0.17/W of residential applications, significantly more than the U.S. Department of Energy (DOE) benchmark of $0.12/W by 2020.
