Advanced Upper Lighting IV Tester for Superior I-V Curve Measurement in Solar Module Analysis

Application:

Our system is engineered for automated electrical performance evaluation of monocrystalline and polycrystalline silicon solar modules. Utilizing an upper lighting approach, this Upper Lighting IV Tester delivers highly accurate I-V Curve Measurement. Manufacturers can efficiently sort and classify solar cells based on detailed electrical criteria. This technology is an indispensable component of a solar panel production line, enabling rigorous quality control and ensuring that only high-grade cells are assembled into modules.

Product Features:

• Customizable Load Board: Designed to accommodate a wide range of battery types (including PERC, TOPCon, HJT, SUNPOWER, IBC, and more), ensuring a thorough electrical performance assessment.

• Efficient Upper Lighting Solar Module Simulator: Implements a direct light structure to accurately mimic solar irradiation, offering realistic conditions for precise I-V Curve Measurement.

• Flexible Installation Options: Supports adaptable configurations of the Upper Lighting IV Tester to meet on-site requirements through both side and top illumination setups.

• Full Spectrum Capability: Covers the wavelength range from 300 nm to 1200 nm, ensuring that the simulator provides a complete spectrum for accurate testing.

• Adjustable Pulse Width: Offers a pulse duration range from 10ms to 150ms, allowing users to fine-tune test parameters for optimal I-V Curve Measurement.

• Advanced Data Acquisition: Integrates a four-wire connection with a high-speed data system to capture accurate, synchronized data from multiple measurement points.

• Temperature Correction: Uses non-contact infrared techniques for precise temperature readings, vital for ensuring the accuracy of I-V Curve Measurement.
