Description

Technical Field

[0001] The utility model belongs to the field of solar power generation equipment, in particular to a fixing device for a solar panel sun tracking system. Background Art

[0002] The solar panel tracking system automatically adjusts the angle of the solar panel so that it is always aligned with the sun to maximize the efficiency of capturing solar energy and thus increase power generation. The solar panel fixing bracket plays a vital role in the solar power generation system. Its main function is to firmly install the solar panel in the designated position and keep the panel at the optimal angle to maximize the capture and utilization of solar energy. Since the width of the fixing bracket in the related art is not adjustable, it can only accommodate solar panels of a specific size. If the size of the panel changes or the project requires the replacement of panels of different specifications, the fixing bracket may not be able to be used, resulting in a problem of limited applicability of the fixing bracket. In addition, during the actual installation process, the non-adjustable width bracket leads to low space utilization, especially in a limited installation area. The layout of the bracket cannot be flexibly adjusted, which may result in a waste of installation space. Since the fixing bracket in the related art does not have a preliminary pre-tightening and positioning function, the contact between the panel and the bracket may not be tight enough, resulting in uneven force in certain parts and prone to stress concentration.
