This paper presents a comprehensive review and comparative analysis of CNN-based approaches for crack detection in solar PV modules. . 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. Therefore, fast and accurate defect detection has become a vital. . Solar cell microcracks, often just 10-100 micrometers wide, can expand under thermal and mechanical stress to significantly impact panel performance. 5% annually if left undetected. . Detection of cracks in solar photovoltaic (PV) modules is crucial for optimal performance and long-term reliability. Three scenarios are defined where these techniques will bring value.
