Main challenges of defect detection in PV systems. Although data availability improves the performance of defect diagnosis systems, big data or large training datasets can degrade computational efficiency, and therefore, the effectiveness of these systems. This limits the deployment of DL-based techniques in practical applications with big data.
Although the terms ‘defects’ and ‘faults’ were interchangeably used in the literature, it was observed that the reference to ‘defects’ was typically related to the physical components or materials used in the PV system, such as physical anomalies in PV modules (e.g., cracks, hotspots, delamination, disconnections, etc.).
The defects on the surface of abnormal PV cells were different from the background in the image, but these defects were generally similar in appearance to the background in the EL image, so it was difficult to distinguish them.
