Four types of faults in a photovoltaic (PV) system. [...] Photovoltaic (PV) system output electricity is related to PV cells' conditions, with the PV faults decreasing the efficiency of the PV system and even causing a possible source of fire. In industrial production, PV fault detection is typically laborious manual work.
Therefore, it is mandatory to identify and locate the type of fault occurring in a solar PV system. 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.
Fault analysis in solar photovoltaic (PV) arrays is a fundamental task to increase reliability, efficiency, and safety in PV systems and, if not detected, may not only reduce power generation and accelerated system aging but also threaten the availability of the whole system.
The faults in the PV panel, PV string and MPPT controller can be effectively identified using this method. The detection of fault is done by comparing the ideal and measured parameters. Any difference in measured and ideal values indicate the presence of a fault.
Any factor which reduces the output is considered as “fault”. It may be temporary (shadows, bird droppings, and dust or snow accumulation on the surface of the PV panel) or permanent (electrical disconnection, wiring losses and ageing).
Besides solar intensity and ambient temperature as main climatic parameters, humidity can be examined as a potential fault source in solar PV systems [77, 78]. For further reading and works pertinent to solar energy utilization in solar collectors, PV panels, and heaters/coolers can be referred in [79 – 96].
