Defects of solar panels can easily cause electrical accidents. The YOLO v5 algorithm is improved to make up for the low detection efficiency of the traditional defect detection methods.
Nevertheless, review papers proposed in the literature need to provide a comprehensive review or investigation of all the existing data analysis methods for PV system defect detection, including imaging-based and electrical testing techniques with greater granularity of each category's different types of techniques.
In this study, a novel system for discovering solar cell defects is proposed, which is compatible with portable and low computational power devices. It is based on K -means, MobileNetV2 and linear discriminant algorithms to cluster solar cell images and develop a detection model for each constructed cluster.
To this end, we propose the design and implementation of an end-to-end system that firstly divides the solar panel into individual solar cells and then passes these cell images through a classification + detection pipeline for identifying the fault type and localizing the faults inside a cell.
Various defects in PV cells can lead to lower photovoltaic conversion efficiency and reduced service life and can even short circuit boards, which pose safety hazard risks . As a result, PV cell defect detection research offers a crucial assurance for raising the caliber of PV products while lowering production costs. Figure 1.
To demonstrate the performance of our proposed model, we compared our model with the following methods for PV cell defect detection: (1) CNN, (2) VGG16, (3) MobileNetV2, (4) InceptionV3, (5) DenseNet121 and (6) InceptionResNetV2. The quantitative results are shown in Table 5.
Many methods have been proposed for detecting defects in PV cells , among which electroluminescence (EL) imaging is a mature non-destructive, non-contact defect detection method for PV modules, which has high resolution and has become the main method for defect detection in PV cells .
