Product Applications

The OEL-S2400 EL Defect Tester serves critical quality control functions across various solar panel manufacturing scenarios:
Pre-Lamination Quality Control
Essential for identifying defects before the irreversible lamination process, saving materials and production costs. The system detects cell cracks, soldering issues, and alignment problems that could compromise the final product quality.
Post-Lamination Verification
Provides final quality assurance for completed modules, ensuring that the lamination process hasn't introduced new defects and verifying the integrity of the finished solar panels before packaging and shipment.
Production Line Integration
Seamlessly integrates into existing solar panel production lines from 5MW to 1GW capacity, supporting various technologies including:
PERC solar modules
TOPCon technology panels
MBB (Multi-Busbar) configurations
IBC and HJT cell technologies
Standard G1, M6, M10, and M12 wafer sizes
Quality Management Systems
Supports comprehensive quality management programs with detailed defect documentation, traceability through barcode integration, and systematic image archiving for quality audits and continuous improvement initiatives.
