Upper Lighting Solar Panel IV Tester
The Upper Lighting Solar Panel IV Tester is a professional device that non-destructively measures the current-voltage (IV) characteristic curve of solar panels or modules under Standard Test Conditions (STC) by illuminating them with simulated sunlight from above. It accurately acquires core performance parameters such as maximum power point (Pmax), open-circuit voltage (Voc), short-circuit current (Isc), fill factor (FF), and conversion efficiency. It is primarily used for quality control, product sorting, and performance evaluation.
Product Features
Top Illumination, Realistic Simulation: Features an overhead lighting design where the light source illuminates the module from above, more realistically simulating sunlight incidence scenarios (especially for framed, double-glass, or modules at specific installation angles), ensuring test conditions are highly consistent with real-world application environments.
Precise Measurement, Core Parameters: Non-destructively, rapidly, and accurately measures the complete current-voltage characteristic curve of solar modules under Standard Test Conditions (STC), and precisely calculates key performance parameters such as open-circuit voltage (Voc), short-circuit current (Isc), maximum power point (Pmax), fill factor (FF), and conversion efficiency.
Efficient & Non-Destructive, Safeguards Production: The testing process requires no flipping or moving of the module under test, significantly improving production line inspection efficiency and avoiding potential damage risks associated with handling and flipping during testing. Particularly suitable for high-speed online inspection and quality control on production lines.
Standardized & Reliable, Quality Assurance: Strictly adheres to international photovoltaic testing standards, providing reliable, repeatable, and traceable test data. It is a core device for module power sorting, factory acceptance testing, incoming material verification, and performance evaluation, effectively ensuring product quality and consistency.
