Solar Simulators & EL Testing Solutions
High-Precision Power Characterization (I-V Testing)
Our advanced solar simulators are the gold standard for measuring the electrical performance of PV modules. Utilizing high-stability Xenon flash technology, these systems provide a Class AAA light spectrum that perfectly replicates natural sunlight. The primary function is to accurately capture the I-V (current-voltage) curve, determining critical parameters such as Pmax, Voc, and Isc. This precise characterization ensures that every module is correctly binned and meets its rated power output before shipping.
Electroluminescence (EL) Defect Detection
To ensure internal structural integrity, our EL testers act as the "X-ray" of the solar production line. By applying a forward bias to the module, the system triggers electroluminescence, which is captured by high-resolution cooling CCD cameras. This non-destructive testing method is essential for identifying "invisible" defects such as micro-cracks, PID (Potential Induced Degradation), inactive areas, and soldering anomalies that cannot be seen by the naked eye but would significantly impact long-term reliability.
Intelligent AI Image Analysis & Sorting
Equipped with proprietary AI-driven software, our EL testers automatically categorize defects with high speed and accuracy. The system eliminates human subjectivity by providing standardized "Pass/Fail" results based on customizable TUV or IEC quality criteria. This smart automation allows for real-time sorting on the production line, ensuring that only modules with zero structural flaws proceed to final packaging, thereby reducing future warranty claims and field failures.
Industrial Throughput & Seamless Integration
Designed for high-volume 24/7 manufacturing, our testing units feature rapid cycle times and automated loading/unloading conveyors. The integrated control system offers full data traceability, linking every I-V report and EL image to the module’s unique serial number. With robust electromagnetic shielding and a compact footprint, these testers are easily integrated into any automated assembly line, providing the final layer of confidence for global solar module manufacturers.
