A defect is an unexpected or unusual happening which was not observed on the PV plant before. However, defects often are not the cause of power loss in the PV plants: they affect PV modules, for example, in terms of appearance (Quater et al.,2014). There are various diagnostic tools and methods to identify defects and failures on PV devices ...
However, this method is based on expanding a UV beam to illuminate an extensive area of the PV sample, making it troublesome as fluorescence signal (typically small) tends to fade quickly. The least used solar panel defect detection method is the scanning electron microscopy (SEM) imaging technique.
6. Discussion and comparative analysis The solar panel defects can be classified as optical and electrical-mismatch-related degradation, such as discoloration of the encapsulant, front cover glass breakage, delamination, shading, cell fracture snail trails, poor soldering, broken interconnection ribbons, and short-circuited cells [ 80 ].
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.
Various types of methods are used to identify defects and failure modes in PV modules. However, visual inspection is the quickest and convenient way to detect defects in a solar panel [ 79] by directly looking at the PV cell using a naked eye or a magnifying glass. Fig. 7 shows examples of visible defects due to weathering. Fig. 7.
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 least used solar panel defect detection method is the scanning electron microscopy (SEM) imaging technique. The spatially resolved images can be obtained from the SEM image, which provides qualitative information about the surface morphology of hot spots caused by imperfect p-n junction properties and material defects [ 58 ].
