Upper Lighting Solar Module Simulator
Application:
This Automated Solar Cell IV Tester is used for automatic testing and result recording of electrical performance parameters of monocrystalline and polycrystalline silicon solar modules through upper lighting method. It's an inseperable part of a solar panel production line.
Products Features:
The equipment meets the top spectral standards in the industry:
1. A+A+A+ performance; The Upper Lighting Solar Module Simulator's three core performance indicators of unevenness, spectral matching, and light intensity stability all exceed industry standards.
2. Full spectrum; The spectral range meets the requirements of 300-1200nm, achieving full spectrum testing of high-efficiency silicon batteries and greatly improving testing accuracy.
3. Four wire connection and a high-speed data acquisition system, ensuring the accuracy of solar cell current measurement.
4. I-V Curve Measurement: Infrared non-contact temperature measurement accurately measures the temperature of components, ensuring the accuracy of temperature correction.
