Solar Panel IV Tester

Overview of Solar Module Tester

The Solar Module Tester is a highly reliable and high-precision testing device designed for solar cells. It uses high-power, long-lifetime imported pulsed xenon lamps as the light source, an imported ultra-high precision four-channel synchronous data acquisition card for data collection, and a professional ultra-linear electronic load to ensure precise test results. It is suitable for use by solar photovoltaic module manufacturers for sorting and analyzing solar cells.

• Professional Linear Scanning Electronic Load: Guarantees measurement accuracy and ensures the linear measurement error within ±2% across the entire measurement range.
• Simplified Software Design: The software is simple to use, with only the correction of relevant coefficients needed during calibration.
• Light Source: Uses the internationally popular pulsed xenon lamp simulator, with a parabolic reflector device to achieve high uniformity of simulated sunlight, avoiding temperature-related test result deviations from steady-state sunlight simulators.
• Imported Xenon Lamp: Ensures the spectral correctness of the light source and long service life.
• Cell Measuring Mechanism: Uses synchronous motor drive, reducing operational noise and minimizing cell damage during testing.
• Voice Reporting Function: Allows relevant measurement parameters to be announced by voice, enhancing measurement efficiency and reducing damage rates.
• Crystalline Silicon Cell Measurement: Uses a four-wire connection to ensure accurate measurements.
• Semiconductor Probe: Measures the temperature of the test cell, ensuring accurate and reliable temperature measurements.
• Short Measurement Intervals: The time interval between tests is less than 5 seconds, enabling fast measurements.
• Human-Machine Interface: The interface is user-friendly, making operation more intuitive.

Environmental Requirements for the Solar Module Tester

• The testing area must be larger than 3m × 5m, with a height of at least 2.5m.
• The room should have an illuminance of less than 100 lux and should be equipped with both heating and cooling air conditioning to stabilize the room temperature around 25℃.
• The power supply should be 220V/2KW, with easy connection, and a reliable grounding system.
• There should be sufficient space for a storage room connected to the testing area, ensuring the temperature of the test cells is similar to the test room temperature.
• The testing room should be equipped with a compressed air source interface. The air pressure should be stable between 5-8 Kg/C㎡.
