In the field of new energy, photovoltaic panels as an important part of solar power generation, its performance and stability are directly related to the efficiency and life of the entire power generation system. However, photovoltaic panels in the production, transportation and installation process, there may be hidden defects for various reasons, these defects are often difficult to detect by the naked eye, but it will have a serious impact on the power generation efficiency and safety of photovoltaic panels. In order to solve this problem, string EL detector came into being and has become an important tool for detecting hidden defects of photovoltaic panels.
WX-EL3 series EL detector is a kind of equipment for non-destructive detection of photovoltaic panels by using the principle of electroluminescence. It can determine whether there are hidden defects in photovoltaic panels by detecting the luminous condition of photovoltaic panels at specific voltages without destroying the structure of photovoltaic panels.
The series EL detector has the technical characteristics of high precision, high sensitivity and high speed. It can quickly scan the entire photovoltaic panel, capture every tiny luminous point, and through image processing technology, these luminous points into intuitive image information, convenient detection personnel for analysis and judgment. In addition, the string EL detector also has the advantages of simple operation and easy to carry, which makes it widely used in the detection of hidden defects of photovoltaic panels.
The hidden defects of photovoltaic panels mainly include cracks, broken grid, black heart, virtual welding and so on. These defects will reduce the power generation efficiency of photovoltaic panels, and even lead to the failure of photovoltaic panels. For example, cracks and broken gates can cause photovoltaic panels to break easily when subjected to external forces, thus affecting their service life; The black heart will cause the photovoltaic panel to produce heat spot effect in the process of power generation, and even cause fire and other safety accidents in serious cases.
String EL detector plays an important role in the detection of hidden defects of photovoltaic panels. It can quickly and accurately detect the hidden defects in photovoltaic panels, and provides strong support for the quality control and troubleshooting of photovoltaic panels. In practical applications, the inspection personnel only need to connect the string EL detector with the photovoltaic panel, set the appropriate detection parameters, and then start the inspection. After the detection is completed, the inspection personnel can judge whether the photovoltaic panel has hidden defects by observing and analyzing the detection result images, and take corresponding repair measures.
