Today, with the vigorous development of the photovoltaic industry, the performance and quality of photovoltaic solar panels are directly related to the efficiency and stability of the entire photovoltaic power generation system. However, due to the influence of production processes, material properties, and long-term operating environments, various defects are inevitable inside solar panels, such as cracks, fractures, and contamination. These defects will not only reduce the power generation efficiency of the solar panels, but also may cause potential safety hazards. Therefore, how to quickly and accurately identify these internal defects has become an important issue that the photovoltaic industry urgently needs to solve. The photovoltaic EL detector emerged as The Times required and became a key tool to solve this problem.

The WX-EL2 photovoltaic EL detector, also known as the electroluminescence detector, is a high-tech device that uses the principle of electroluminescence to detect internal defects in photovoltaic solar panels. It adopts a non-contact detection method and will not cause any damage to the solar panels. Meanwhile, this instrument features fast detection speed, high accuracy and simple operation. By emitting light of specific wavelengths and exciting the electrons inside the solar panel, it makes them emit weak light signals. The intensity and distribution of these light signals can reflect the defect conditions inside the solar panel.

The photovoltaic EL detector is widely used in the operation and maintenance management of photovoltaic power stations, the quality control of solar panel production, as well as in scientific research and teaching, etc. In the operation and maintenance management of photovoltaic power stations, this instrument can regularly inspect the solar panels, promptly identify and address potential safety hazards, and ensure the stable operation of the power station. In terms of quality control in the production of solar panels, the photovoltaic EL detector can conduct a 100% full inspection of the solar panels on the production line, effectively eliminating substandard products and enhancing product quality and market competitiveness.
