At the same time, according to different terrains and locations, daytime solar energy can be effectively utilized to improve the efficiency of photovoltaic power generation.

Flexible brackets can easily cope with complex mountains or other irregular terrains and have strong adaptability.

[0003] Flexible brackets solve the problems of large spans and high clearances, but since their components are mainly supported by steel wire ropes, they may be twisted under strong winds, causing collisions and hidden cracks in photovoltaic components. A Chinese patent with patent publication number CN213661514U discloses a flexible bracket system and photovoltaic power station for photovoltaic power stations. The patent enhances the stability of the flexible structure through the structure of three suspension cables, effectively preventing photovoltaic components from being affected by strong winds. However, due to the increase in the number of photovoltaic panels, it is still unable to resist strong winds, and due to the increase in the number of suspension cables, it is impossible to adjust the angle of the photovoltaic panels, which limits the improvement of power generation efficiency.
