The results of comparative experiments on the solar panel defect detection data set show that after the improvement of the algorithm, the overall precision is increased by 1.5%, the recall rate is increased by 2.4%, and the mAP is up to 95.5%, which is 2.5% higher than that before the improvement.
With the deepening of intelligent technology, deep learning detection algorithm can more accurately and easily identify whether the solar panel is defective and the specific defect category, which is broadly divided into two-stage detection algorithm and one-stage detection algorithm.
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 ].
In order to avoid such accidents, it is a top priority to carry out relevant quality inspection before the solar panels leave the factory. For the defect detection of solar panels, the main traditional methods are divided into artificial physical method and machine vision method. Byung-Kwan Kang et al. [
Because most of the target pixels of the solar panel defect detection data set are small, it is necessary to improve the feature recognition ability of the model.
