ADVANCED EL INSPECTION FOR PV MODULE QUALITY CONTROL
Solar Module EL Tester
An automated inspection system integrating electroluminescence (EL) imaging and visual inspection for photovoltaic module quality evaluation, defect detection, and production control.
Comprehensive PV Module Defect Detection With EL Imaging Technology
The Solar Module EL Tester is an automated inspection solution designed for photovoltaic module quality control, production inspection, and reliability evaluation.
By applying forward current to PV modules in a dark environment, the system captures high-resolution electroluminescence images to reveal internal defects that cannot be detected through visual inspection.
Combined with advanced image processing and intelligent defect analysis, the system enables fast identification of micro-cracks, broken fingers, inactive areas, soldering defects, and other quality issues, helping manufacturers improve production efficiency and module reliability.
