PV Module EL Testing Equipment for Accurate Solar Panel Inspection
Quality and reliability are the most important aspects in the solar energy industry. The actual performance of any solar panel depends not only on its design or material, but also on its testing process. An important part of this testing process is PV module EL testing equipment , which helps in testing the internal quality of the solar module. What is EL Testing and why is it important? EL, i.e. Electroluminescence Testing, is an advanced technology through which micro-cracks, cell damage, soldering defects and hidden faults present inside the solar module can be easily identified. This testing is not possible with the naked eye, but EL testing equipment detects these problems at an early stage. Defects in solar panel production, if not detected in time, can lead to reduced power output, premature module failure, and loss of company reliability. How PV Module EL Testing Equipment Works This device passes electrical current to the solar module, causing the cells to emit mild light. A h...
