Detecting cracks in solar panels through electrical current flow analysis. The development of convolutional neural networks (CNNs) has significantly improved crack detection, offering improved accuracy and efficiency over traditional methods. These defects, while initially microscopic, can reduce power output by up to 2. 5% annually if left undetected. Conventional visual inspection methods. . This work aims to developing a system for detecting cell cracks in solar panels to anticipate and alert of a potential failure of the photovoltaic system by using computer vision techniques. Three scenarios are defined where these techniques will bring value. The proposed method is designed with the following modules preprocessing, enhancement, feature computations, classification and crack segmentation.
