[0003] With respect to the above-mentioned related technologies, the inventors believe that it is difficult for the test bracket in the traditional technology to effectively adjust the installation angle of the photovoltaic module. Therefore, it is difficult to adjust the angle of light irradiating the photovoltaic module to test the data. In addition, the traditional bracket generally needs to fix the photovoltaic module to the bracket by bolting, which will result in the need for external tools for disassembly and installation, which is more troublesome and has defects. Therefore, an outdoor test bracket for the power generation performance of photovoltaic modules is proposed to solve the above problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
