Manufacturers perform incoming and outgoing inspections, such as electroluminescence (EL) or electroluminescence crack detection (ELCD) testing. . The manufacturing of photovoltaic cells is a complex and intensive process involving the exposure of the cell surface to high temperature differentials and external pressure, which can lead to the development of surface defects, such as micro-cracks. Currently, domain experts manually inspect the. . However, PV panels are prone to various defects such as cracks, micro-cracks, and hot spots during manufacturing, installation, and operation, which can significantly reduce power generation efficiency and shorten equipment lifespan. These defects, while initially microscopic, can reduce power output by up to 2. 5% annually if left undetected. The silicon used in solar PV cells is very thin (in the range of 180 +/- 20 microns) and hence is susceptible to damage easily if the PV module's. . Cracks in solar panels represent silent threats that progressively degrade performance across decades of operation. The technique consist of three stages, the first stage combines two images, the first image is the crack-free (healthy) solar. .
