The Spi-Module QA is an automated photovoltaic module testing system that combines the advanced I-V measurement capabilities of the Spi-Sun Simulator with high voltage isolation (Hi-Pot) and ground continuity testing. Integrated automation provides efficient module alignment, transport, probing and testing. An optional label printer/applicator completes the process.
A module conveyor moves modules to the Spi-Sun Simulator, which tests photovoltaic modules under simulated Air Mass 1 5 Global terrestrial conditions. A filtered, pulsed xenon light source closely matches the solar spectrum while avoiding the excessive solar cell heating caused by continuous sources. The spectrum is carefully filtered to meet ASTM and international spectral distributions (ASTM E927 Class A), which facilitates the testing of thin film as well as crystalline silicon materials. A four-point probe automatically contacts terminals in the module junction box or on a contact block attached to the module output leads. An electronic load measures the module's I-V curve and the data is acquired, processed, and displayed on the computer screen.
A conveyor moves modules from the Spi-Sun Simulator to an enclosed test area, where the module is probed for both high voltage and ground continuity tests. Test probes make contact to the module's output terminals and any exposed conductive components, typically four frame members. After the high voltage test, the test probes are automatically reconfigured, and the ground continuity test is executed. Test data is collected and displayed on a computer screen. Test conditions are fully programmable and can be set to comply with ANSI/UL 1703 and IEC 61215 standards.
Module probing and transport through the test system is controlled by the same computer that performs the high voltage, ground continuity and Spi-Sun Simulator tests. After all of the tests are completed, an optional label printer/applicator prints a label and applies it to the back of the module.
