Overview
The portable EL defect detector is designed for hidden defects in photovoltaic modules. It uses electroluminescence technology to excite the recombination of charge carriers inside the module, and presents micrometer level defects such as hidden cracks, virtual soldering, and fragments clearly through a high-resolution imaging system. The device adopts an integrated lightweight design, equipped with an intelligent touch screen and wireless image transmission function, supporting single person outdoor rapid detection and real-time image analysis. The built-in AI assisted diagnostic module can automatically mark abnormal areas, providing efficient and accurate non-destructive testing solutions for photovoltaic power plant acceptance, operation and maintenance, and component quality traceability.
