The characteristics are that the fixed bracket has the difficulties of high raw material cost, longer construction period, high labor cost and the like in the construction process. In recent years, a rigid purline is changed into a steel strand mode by a flexible photovoltaic support to form a flexible rope structure, and a photovoltaic module is directly installed on two module installation ropes with inclination angles so as to better receive sun illumination; because the flexible support adopts a mode of stretching the prestressed cable between the two fixed points, the two fixed points adopt a rigid foundation to provide reaction force, and the installation with a larger span can be realized.

The flexible photovoltaic bracket relieves the problems existing in the rigid bracket system to a certain extent, but the side beams are easy to deform under stress when the flexible photovoltaic bracket is constructed, and the side beams need anchoring by anchor piles, such as the flexible bracket system with zero deflection, high damping and high work efficiency disclosed in Chinese patent (bulletin number: CN 216873114U), and anchor piles are arranged on the outer sides of the pipe piles, wherein the heights of the anchor piles are lower than the heights of the pipe piles; therefore, in order to ensure the balance of the flexible photovoltaic support system, the anchor pile structure is increased, the pile consumption and the steel consumption are still large, the cost of the photovoltaic support system is high, and the land utilization rate is reduced by building the anchor pile structure.
