AI Technical Summary

Technical Problem

In existing photovoltaic module power testing, it is difficult to ensure the consistency of the distance between the module and the light source, and the measurement error caused by the incomplete shading of the back of the module and stray light affect the test accuracy.

Method used

A photovoltaic module power testing device was designed, including a test chamber, a light source, a light-blocking module, and a module gripping device. The movable light-blocking module and positioning device ensure that the back of the module is sealed. Combined with a robotic arm and a fixed suction cup, the module can be accurately positioned and its angle adjusted to ensure that the photovoltaic module is not affected by stray light during the test.

Benefits of technology

It improves the precision and accuracy of photovoltaic module power testing, adapts to the testing needs of modules of different sizes, reduces the risk of module damage, and ensures the reliability of test data.
