These results indicate average values of 93.93% accuracy, 89.82% F1-score, 91.50% precision, and 88.28% sensitivity, respectively. The proposed method in this study accurately classifies photovoltaic panel defects based on images of infrared solar modules. 1. Introduction
The results obtained indicate that the proposed method has significant potential for detecting faults in photovoltaic panels. Training the model from scratch has allowed for better processing of infrared images and more precise detection of faults in the panels.
Another significant aspect of this study is that the Efficientb0 model has been trained from scratch using infrared solar module images. The purpose of this approach is to optimize the model's ability to detect faults in photovoltaic panels.
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.
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.
