Faults in a Large-scale photovoltaic installation: A Review

The global warming and realisation that fossil fuel is limited, has been a drive over the years to move to renewable energy sources. Consequently, solar energy and other renewable energy sources are currently being exploited. The fast development of photovoltaic technologies makes the systems one of the leading methods to effectively exploit the RES. In recent times, the PV system are done at large to augment the classical energy supply. However, large-scale photovoltaic installations possess challenges of being susceptible to occurrence faults Therefore, it is imperative that faulty modules are detected and isolated to preserve the efficiency of the overall PV system. This paper presents a review of various faults often encountered in large-scale PV installation.
