Research on Solar Panels Online Defect Detecting Method

Taking solar photovoltaic panels as the research object, infrared diagnosis technology is used to inspect the quality of crystalline silicon solar panels, and using infrared detecting principle of infrared thermal imager to design a set of device, which can detect the internal and surface defects of the solar panels. Common defects such as black piece, broken gate, crack and fragment can be detected and classified according to the infrared image characteristics of the four kinds of defects, also it can quickly locate the defects. Experiments show that, after image processing of the images captured by the infrared imager, it can be easily and visually to determine whether a photovoltaic panels is flawed. Last but not least, to classify the defects.
