High-Resolution Multi-Camera EL Tester | Automated EL Defect Testing System for Solar Panel Production Lines

Technical specifications:
Application:

Our system is engineered as an advanced EL Tester designed to thoroughly inspect solar modules. It effectively detects a wide range of defects—such as hidden cracks, fragments, faulty soldering, grid breaks, and other anomalies—that can impact conversion efficiency. This comprehensive detection process is crucial for quality control in an Electroluminescence test sale environment on a busy Solar Panel Production Line.

Machine Feature:

• Multi-Camera Direct Capture:
  The system employs multiple cameras to capture high-quality images from different angles, ensuring precise imaging necessary for accurate defect identification by the EL Tester.

• Sealed Optical Path:
  Its closed optical design minimizes external interference (e.g., dust and ambient light), ensuring long-term, stable operation. This makes it particularly suitable for various environmental conditions in a Solar Panel Production Line and critical for Electroluminescence test sale applications.

• Bilingual Interface and Barcode Scanning:
  Featuring both Chinese and English interface options, the system supports automatic or manual scanning of graphical codes. Files are saved automatically with barcode-based names, streamlining workflow and ensuring efficient data management.

• Detailed Image Analysis:
  The system allows captured images to be enlarged for closer inspection, enabling users to make precise judgments during defect detection.
