This paper presents a defect analysis and performance evaluation of photovoltaic (PV) modules using quantitative electroluminescence imaging (EL). The study analyzed three common PV technologies: thin-film, monocrystalline silicon, and polycrystalline silicon.
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 technical demand in the industry.
Traditional methods for photovoltaic panel defect detection primarily rely on manual visual inspection or basic optical detection equipment, both of which have significant limitations. Manual inspection is inefficient, prone to subjective bias, and often fails to identify subtle or hidden defects.
Classifying defects in photovoltaic modules is essential for understanding their effects on overall energy generation. Different types and severities of defects, such as cracks, PIDs, LeTID etc. can significantly affect module performance. Even minor defects can aggregate to impact the global energy output of photovoltaic systems.
Photovoltaic panel defect detection presents significant challenges due to the wide range of defect scales, diverse defect types, and severe background interference, often leading to a high
In addition to the small number of manufacturing defects, it is normal for solar photovoltaic (PV) cells to experience a small amount of degradation over time. Solar panels must operate for many years in a
