Research Of Online Detective System For Defects In Solar Panels

With the technical development and economical soaring ,the traditional energy sources has become increasingly unable to meet the needs of the people, and its own limited production constraint the energy development and utilization, at the same time, the environmental pollution which the consumption of the traditional energy sources has bring is also affecting the health living of people. In this context, the emergence of new energy has received more and more attention and utilization in daily life, and the representative of the new energy-solar energy has playing an very important role. Photoelectric conversion is the most widely using of the solar energy, solar panels as the basic unit, how to reduce the breakage rate is not also improve the passing rate of finished products and the finished grade, the more important is it can reducing the use of silicon material, played a saving energy, cut costs, increase capacity effect.In this paper, taking"Damage Detection of Solar Panels"as the research object and according to the EL principle, through Near-infrared CCD camera to image, using PC designed image processing software, the author completed the On-line detection function.This study design is used in the chamber for on-line detection, through the opening and closing windows which can be controlled to interference the blocking of external light. this darkroom embedded every links which is need detection of the solar cell production line, With the production line to achieving component loading and processing power at the same time. This imaging device reduce the influence of temperature on the imaging by validation method. Using the mirror reflection principle, growth of optical, reduces the image distortion, is also decreases the geometry of the device. Through developing the reliable and frequent operation soft-off controlled current source, reducing the impact of switching on and switching off for the power, improving the life of the equipment further. The image processing is added in the later period, improve the clarity of image damage defects effectively. Design the simple to use operating software, achieving automatic recognition of the number of the measured components, and have saving, viewing and other functions.
