Description

Technical Field

[0002] At present, photovoltaic modules need to undergo various tests during the research and development and manufacturing process. During the testing process, the photovoltaic modules need to be installed and fixed on the test device. However, in the existing test device, the photovoltaic module can only test one side each time it is installed. When testing the other side, the photovoltaic module needs to be removed and reinstalled, which is cumbersome and greatly affects the efficiency of the test. In addition, the existing test device can only test photovoltaic modules of fixed size, which has a narrow scope of application and is inconvenient to use. Most of the existing test devices are driven by motors to rotate, and when testing in remote areas, it is necessary to bring a battery pack with you.
