What happens if a fault occurs in a solar PV system?
Reduced real time power generation and reduced life span of the solar PV system are the results if the fault in solar PV system is found undetected. Therefore, it is mandatory to identify and locate the type of fault occurring in a solar PV system.
How to identify a fault in a PV panel?
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.
Is humidity a potential fault source in solar PV systems?
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].
Why do PV panels need a fault diagnosis tool?
Continuous determination of faults must be carried out to protect the PV system from different losses, so a fault diagnosis tool is essential to the reliability and durability of the PV panels. Fault detection and diagnosis (FDD) methodologies include three main approaches as shown in Fig. 3.
What are the different types of solar PV faults?
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. Once a fault is located and detected, an appropriate diagnosis method needs to be used to rectify it.
Why is fault diagnosis important for photovoltaic systems?
The reliable performance and efficient fault diagnosis of photovoltaic (PV) systems are essential for optimizing energy generation, reducing downtime, and ensuring the longevity of PV installations.
