Technical specifications:
Application:
Specifically designed for use by solar photovoltaic (PV) panel manufacturers, this equipment is ideal for sorting and performing analytical tests on solar panels within a Solar Cell Production Line. It integrates the capabilities of an Automatic IV Tester and an IV PL Tester to perform comprehensive assessments. In addition, the system supports IV Curve Measurement for detailed analysis and functions as a Solar Cell PL+IV Integrated Tester. This multi-functional setup helps manufacturers efficiently assess panel performance, quality, and consistency, ensuring industry standards are met and production processes are optimized..
Machine Feature:
The solar cell tester serves as a high-reliability, high-precision solar battery test equipment and operates as an Automatic IV Tester in the Solar Cell Production Line. As an advanced IV PL Tester, it is specifically engineered for testing solar batteries, providing exceptional reliability and precision to deliver accurate, consistent test results under various conditions. The design also incorporates IV Curve Measurement to profile the solar cell performance in detail, enhancing its role as a Solar Cell PL+IV Integrated Tester.
Key features include:
Simulator Light Source:
The equipment adopts a high-power, long-life imported pulses xenon lamp. This choice is vital for the Automatic IV Tester mode, ensuring a consistent, durable light source that maintains realistic testing conditions across the Solar Cell Production Line.
Data Acquisition:
An imported ultra-high-precision four-channel synchronous data acquisition card enables simultaneous test data collection, boosting efficiency in both IV PL Tester and Automatic IV Tester operations. This precision supports the integrated functionality of the Solar Cell PL+IV Integrated Tester.
Load Control:
A professional superlinear electronic load is integrated to ensure that test results are accurate. This component is essential for IV Curve Measurement and maintains load conditions that closely simulate real-world performance.
Non-contact Detection:
To avoid secondary damage to the battery, the system employs non-contact detection technology, ensuring that the solar cells remain undamaged while delivering reliable results within the Solar Cell Production Line.
