Description

Technical Field

[0001] The utility model belongs to the technical field of testing equipment, and in particular relates to testing equipment for solar photovoltaic cells. Background Art

[0002] Before photovoltaic cells are put into practical use, accurate testing of their current-voltage characteristics is crucial. This testing is typically performed by illuminating the photovoltaic panels with simulated sunlight to obtain their current-voltage characteristic curves. However, given that the sun's position in the sky changes over time (e.g., from sunrise to sunset), photovoltaic cells in real-world applications receive sunlight at varying angles and intensities, which directly affects their power generation efficiency.

[0003] While existing test equipment can effectively secure photovoltaic panels to prevent movement during these tests, it generally lacks the ability to adjust the panel's angle. This limitation prevents the test environment from fully simulating the various lighting conditions photovoltaic cells may encounter in actual use, affecting the comprehensiveness and accuracy of test results. This also limits the test equipment's ability to accurately plot the current-voltage characteristic curves of photovoltaic cells at different tilt angles.

[0004] Therefore, in order to solve the above problems, it is necessary to design a testing device for solar photovoltaic cells. Utility Model Content

[0005] The purpose of the utility model is to provide a test device for solar photovoltaic cells, so as to solve the technical problem that the angle of the photovoltaic cells in the existing test devices cannot be adjusted.

[0013] Furthermore, a second support arm is provided on the base;

[0014] The second support arm is arranged on one side of any first support arm;

[0021] The hinge is connected to the simulated light source.

[0022] Furthermore, the fixing fixture includes: a pad provided on the support member, an L-plate provided on the support member, and a pressure plate provided on the L-plate; wherein

[0023] The L-plate is in contact with two adjacent side surfaces of the backing plate; and

[0025] Furthermore, the fixing tool further comprises: two rubber sheets;

[0026] Any of the rubber sheets is disposed on top of the pad; and
