Application:
The IV EL Integrated Tester is designed for solar panel production line integration, enabling manufacturers to perform precise sorting, electrical analysis (IV testing), and defect detection (EL testing) in a single system. Ideal for PV panel manufacturers requiring end-to-end quality assurance.
Machine Features:
Dual-Function Testing: Combines an IV Tester and EL Tester into one streamlined unit, delivering high reliability and precision for solar cell evaluation.
Advanced Light Source: Equipped with high-power, long-life imported xenon lamps (IEC/JISC-compliant) for consistent solar panel production line testing.
Ultra-Precision Data Acquisition: Utilizes imported four-channel synchronous data cards and superlinear electronic loads to ensure ≤1% test error in electrical properties.
Non-Contact Detection: Safeguards solar cells against secondary damage during IV testing and EL testing.
Seamless Integration: Fully compatible with automated solar panel production line workflows, supporting 2000 pcs/hour throughput.
