The methodology involved in the fault classification and early detection of solar panel faults begins with the selection of the dataset. Two types of image datasets are used in this case, namely the aerial image dataset of solar panels and the electroluminescence image dataset of solar panel cells.
Both IV curve-based and thermal image-based ML models are commonly employed for fault detection in solar panels after their installation. These models serve as ongoing monitoring tools to ensure the panels' optimal performance and identify any potential issues.
The general block diagram of the solar PV monitoring system is shown in Figure 1. The objective of the solar PV monitoring system is to analyze all the possible data, which affects the performance of solar PV system in real time and to give the correct information about the that occurred in the solar PV system.
Fault detection is an essential part of PV panel maintenance as it enhances the performance of the overall system as the detected faults can be corrected before major damages occur which a significant effect on the power has generated.
The condition monitoring and fault detection in large-scale solar farms is essential to ensure the longevity of equipment and maximized power yield. The large-scale solar farms comprise of thousands of solar panels that are spread over many hectares of land.
This PV system is capable of studying faults among modules with different array configurations. In order to test the ability of the proposed approach to detect and locate the faults and identify the fault types, a series of line-line faults within the string are used in the simulations.
