String Repair EL Station
Application: 1. Defect Detection: It detects various defects in solar cell strings, such as cracks, black spots, misalignment, and other defects that could affect the performance of solar panels using Electroluminescence (EL) imaging technology. 2. High Efficiency and Fast Testing: The machine offers quick testing (≤2 seconds per string), making it ideal for high-speed production lines where fast and accurate quality control is essential.
