The other surfaces of the photovoltaic panel that are not the front or back can be collectively referred to as sides (including lateral sides and longitudinal sides). In order to obtain the best irradiation angle, the photovoltaic panel needs to be placed obliquely, so the two cables are arranged one high and one low vertically, and the photovoltaic panel is fixedly connected to the two cables at a certain angle. When air at a certain speed blows through the photovoltaic panel, the photovoltaic panel will generate vertical displacement, torsion and/or random vibration under the action of wind force. Due to the difference in height between the two cables, each cable is connected to the back of the photovoltaic panel through multiple buckles. When the wind load increases to a certain extent, the direction and magnitude of the force are different so that each buckle The pulling force is increased, and the photovoltaic panel may be torn by the pulling force generated by the buckle. The two cables are steel strands with a certain pre-tightening force, and the longitudinal stiffness of the two cables is weak. When the wind load increases to a certain extent, the two cables also have the risk of damage.

In some embodiments, referring to FIG. 1 , multiple rows of tie rod assemblies 210 may be distributed at equal intervals in the lateral direction, and the number of photovoltaic panels 400 installed between every two adjacent rows of tie rod assemblies 210 is equal. The multi-row tie rod assembly 210 is mainly used to increase the wind vibration resistance of the first main cable 110-1 and the second main cable 110-2, and the multi-row tie rod assembly 210 distributed at equal intervals can make the first main cable 110-1 and the second main cable 110-1 and the second main cable 110-2 The longitudinal rigidity of the two main cables 110-2 increases evenly, and the photovoltaic panel 400 is less likely to be damaged due to severe local stretching and deformation of the cables.

In some embodiments, the wind resistance module 200 may include multiple rows of tie rod assemblies 210 . Each row of tie rod assemblies 210 is arranged between two adjacent rows of main cable units 110 , and it can also be understood that each row of tie rod assemblies 210 is arranged between two adjacent rows of photovoltaic panels 400 .

FIG. 2 is only shown schematically, and does not limit the specific number of rows of photovoltaic panels 400 , main cable units 110 and pull rod assemblies 210 in this specification. In some embodiments, the number of rows of tie rod assemblies 210 can be set according to the actual requirements of the photovoltaic support as a whole, so as to meet different terrain and power requirements. For example, there may be six rows of photovoltaic panels 400 and main cable units 110 , and five rows of tie rod assemblies 210 . For another example, there may be seven rows of photovoltaic panels 400 and main cable units 110 , and six rows of tie rod assemblies 210 . For another example, there may be seven rows of photovoltaic panels 400 and main cable units 110 , then six rows of tie rod assemblies 210 , and so on.

Since the photovoltaic panels 400 on the photovoltaic support are arranged in an array with a certain inclination angle, when this flat plate structure with an inclination angle faces the wind, generally speaking, the front row photovoltaic panels 400 facing the wind direction will bear the greatest wind force, and the slightly rear row photovoltaic panels 400 Since the front row of panels 400 has withstood most of the wind force, compared with the rear photovoltaic panels, the wind force is less. Therefore, the tie rods in the tie rod assembly 210 that are first to bear the wind load at the front row and the back row of each span photovoltaic support can be rigid rods.

In some embodiments, the photovoltaic support in FIG. 2 includes five rows of photovoltaic panels 400 and also includes five rows of main cable units 110 .
