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.
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].
Apart from the faults occurring due to environmental and physical factors, electrical faults are also very common in PV systems. Most of electrical faults are caused mainly due to improper or loose connections of conductors or poor soldering between joints.
In addition, the efficiency drop in a solar PV system is because of the effect of various kinds of faults and failures, which the system suffers. According to the test results conducted in 2010, the annual power loss in the solar PV system is about 18.9% due to its faults and failures .
This work proposes an automated reconfiguration system to manage two types of faults in any position inside the solar arrays. The faults studied are the short-circuit to ground and the open wires in the string. These faults were selected because they severely affect power production.
