Description
technical field [0001] The present invention relates to the field of new energy technologies, in particular to a detection device and method for a broken grid defect of a solar battery panel. Background technique [0002] As a clean energy source, solar energy converts the sun's light energy into other forms of energy. During the entire energy conversion process, no other harmful gases or solid wastes are produced. It is an environmentally friendly, safe, and pollution-free new energy source. At present, the traditional energy represented by coal, oil, and natural gas has been gradually exhausted, so vigorously developing new energy industries is an inevitable trend in the development of the world today. With the rapid development of the global photovoltaic cell industry, the scale of the domestic solar cell industry is also expanding. Effective detection of defects in solar panels plays a vital role in the photoelectric conversion efficiency. Detecting defects on the surfa...
