In the tide of green energy, photovoltaic panels as the core components of solar power generation, its quality and efficiency are directly related to the stability and economic benefits of the entire system. However, even in the most sophisticated production line, it is difficult to completely avoid those invisible killers that are difficult to discern by the naked eye - internal defects of photovoltaic panels. Fortunately, with the progress of science and technology, el tester came into being, it is like the photovoltaic industry's "X-ray machine", so that hidden problems can not be hidden.
The WX-EL1EL tester generates visible light (electroluminescence) by applying a specific voltage or current to a photovoltaic panel to stimulate its internal electronic transition. This process is like a full-body scan of the photovoltaic panel, and any slight cracks, impurities, poor welding and other defects will emit different intensity of light in the dark, which is captured and recorded by high-definition cameras. This non-contact, non-destructive testing method not only improves the accuracy and efficiency of the test, but also greatly reduces the risk of secondary damage to photovoltaic panels.
The EL tester can capture extremely weak luminous differences, and even small defects are difficult to escape its "normal eye". This high-precision detection ensures that the photovoltaic panel can be strictly screened before leaving the factory to improve the overall quality; Combined with advanced image processing technology, EL tester can quickly generate the luminous image inside the photovoltaic panel, and visually display the location and nature of the defect through color, brightness and other parameters, which is convenient for rapid positioning and classification processing.
Modern EL tester has achieved a high degree of automation, from loading photovoltaic panels to detection, analysis, report generation, the whole process without manual intervention, greatly improving the detection efficiency and accuracy, reducing labor costs. As well as integrated big data analysis function, EL tester can continuously accumulate test data, provide valuable information such as quality traceability and process improvement for photovoltaic panel manufacturers, and promote continuous optimization and upgrading of products.
