Should PV system fault detection methods be based on onsite fault detection?

Future research directions are recommended for both industry and academia to advance PV fault detection methods. PV systems are prone to external environmental conditions that affect PV system operations. Visual inspection of the impacts of faults on PV system is considered a better practice rather than onsite fault detection mechanisms.

What are the different types of PV fault detection methods?

In the existing literature, three fundamental PV fault detection approaches are proposed, that are, vision-based detection, image-based detection with classification, and data analytics-based detection [, , , ]. Vision- and imaging-based techniques have been widely used to detect visual PV faults .

Can automatic fault detection be implemented in photovoltaic arrays?

This work presents a methodology for automatic fault detection in photovoltaic arrays, which is intended to be implemented in Colombia, in zones with difficult access and not interconnected to the ...

Can neural networks detect faults in photovoltaic systems?

A fault diagnosis technique for photovoltaic systems based on neural networks is proposed by (Chine et al., 2016 ). Two different algorithms are developed to detect and classify eight different faults. The results demonstrated that this technique is highly capable of localizing and identifying the different kind of faults.

What is PV fault detection using DL?

PV fault detection using DL enables the algorithms to identify and classify specific anomalies based on the characteristics of the given dataset . In addition, it is possible to modify a particular algorithm's learning parameters for the specific fault detection.

Does varifocalnet detect photovoltaic module defects?

The VarifocalNet is an anchor-free detection method and has higher detection accuracy 5. To further improve both the detection accuracy and speed for detecting photovoltaic module defects, a detection method of photovoltaic module defects in EL images with faster detection speed and higher accuracy is proposed based on VarifocalNet.
