Solar Module IV Tester
A Solar Module IV Tester is a key professional inspection device used to rapidly and accurately measure and plot the current-voltage (IV) characteristic curve of photovoltaic (solar) modules by simulating solar irradiance under Standard Test Conditions (STC). It comprehensively analyzes core performance parameters such as open-circuit voltage, short-circuit current, maximum power point, fill factor, and conversion efficiency. This enables the evaluation of module power output capability, detection of potential defects, quality binning, and verification of product specification compliance.
Product Features
High-Speed and Precise Measurement: Utilizes advanced electronic load and control systems to complete a full IV curve scan within seconds, providing high-precision current, voltage, and power data. Meets the requirements for high efficiency and throughput on production lines while ensuring the reliability of test results.
Comprehensive Parameter Analysis: Measures not only basic parameters like open-circuit voltage (Voc) and short-circuit current (Isc), but also accurately calculates and reports key performance indicators such as maximum power point (Pmax), voltage at maximum power (Vmp), current at maximum power (Imp), fill factor (FF), and conversion efficiency (η). Provides comprehensive data support for module performance evaluation and quality binning.
Compliance with Standards and Automation Integration: Strictly adheres to international/domestic photovoltaic testing standards such as the IEC 60904 series, ensuring standardized test conditions and comparable results. Equipped with rich communication interfaces for easy integration into automated production lines or laboratory information management systems. Enables automated testing processes, real-time data upload, and traceability management, enhancing overall quality inspection efficiency.
Stable, Reliable, and Intelligent Diagnostics: Employs high-quality components and robust design to ensure long-term stable operation in industrial environments. Some high-end models feature intelligent analysis capabilities, enabling potential defect warnings based on abnormal IV curve shapes (such as steps, burrs, slope changes, etc.). Assists in quickly locating issues (e.g., micro-cracks, hot spots, poor soldering, PID effect), thereby improving quality control levels.
