The procedure to evaluate the integrity of solar panels specifically for hidden cracks is known as the Thermography inspection. This method utilizes infrared thermography to identify issues that may not be visible to the naked eye. . Solar cell inspection by machine vision with InGaAs short-wave infrared (SWIR) cameras reveals voids in silicon boules before slicing them into wafers to produce mono-crystalline solar cells. Inspection of the resulting wafers with SWIR permits detecting defects, hidden cracks or saw marks inside. . To address the challenges of high missed detection rates, complex backgrounds, unclear defect features, and uneven difficulty levels in target detection during the industrial process of photovoltaic panel defect detection, this article proposes an infrared detection method based on computer vision. . This study presents a new approach for detecting defects in photovoltaic modules by applying infrared images. It shows a high level of accuracy and efficiency over traditional manual inspections by employing advanced algorithms to identify issues like cracks, hot spots, short circuits, and. . Abstract—Utility-scale solar arrays require specialized inspection methods for detecting faulty panels.
