[Technical field]

[0001] The utility model belongs to the technical field of solar energy component testing, in particular to a downward-lighting photovoltaic component testing device. [Background technology]

[0002] During the photovoltaic module testing process, the module needs to be illuminated. In order to ensure the reliability and accuracy of the test results, the light source is irradiated on the photovoltaic module without any obstruction in the middle. Since the photovoltaic module is generally placed on a conveyor line for testing, if the tester illuminates the conveyor line from below, the amount of light entering the bottom edge of the module will be blocked. Therefore, in the prior art, IV testing of photovoltaic modules generally uses a light source to illuminate from above the photovoltaic module, and the test probe detects the electrical connection from below or above the photovoltaic module. For example, a photovoltaic module power tester disclosed in patent publication number CN 111323620 A adopts the method of illuminating from above and detecting from below. The conveyor line transports the solar module to the top of the floating test platform. After the alignment mechanism corrects the position of the solar module, the lifting cylinder of the floating test platform lifts the detection module to the set position of the test junction box, and the tester illuminates from above to perform a power test. However, the following problems still exist for the power test equipment of top lighting: during the test, the power of the photovoltaic module cannot be tested directly, but it must be converted through a simulator before the test, which increases the complexity of the test process, reduces the efficiency of the test, and increases the cost of the test.
