Design and Experimental Study of a Wind-Resistant Solar Panel Bracket with Automatic Solar Tracking

To address the weaknesses of conventional fixed solar panel brackets, namely poor wind resistance and a power-generation efficiency limited by the solar incidence angle, this paper designs an integrated solar panel bracket system that combines wind-speed monitoring, graded wind resistance and intelligent solar tracking. An optoelectronic anemometer is used to acquire real-time wind-speed data, and a dual-threshold control strategy is adopted to adjust the panel tilt and to lower the panel into a protective position. Four photoresistors arranged around the panel detect the light distribution, and stepper motors drive the bracket in two dimensions so that the panel always faces the sun. A prototype was developed through three-dimensional modelling, part machining and control-system programming, and its core functions were verified by simulation tests. The results show that the bracket tracks the solar azimuth stably and remains structurally stable under low to moderate wind speeds, achieving a balance between improved power generation and operational safety. The study also reveals a limitation of structural stability under high wind speeds, which will be addressed by further structural optimization. Economic and environmental assessments indicate that the design has high engineering feasibility and sustainability.
