What are the characteristics of a cable-supported photovoltaic system?

Long span, light weight, strong load capacity, and adaptability to complex terrains. The nonlinear stiffness of the new cable-supported photovoltaic system is revealed. The failure mode of the new structure is discussed in detail. Dynamic characteristics and bearing capacity of the new structure are investigated.

What factors affect the bearing capacity of new cable-supported photovoltaic modules?

The pretension and diameter of the cables are the most important factors of the ultimate bearing capacity of the new cable-supported PV system, while the tilt angle and row spacing have little effect on the mechanical characteristics of the new type of cable-supported photovoltaic modules.

What are the mechanical properties of a tracking photovoltaic support system?

In terms of the mechanical properties of the actual components of the tracking photovoltaic support system, the bar element and shell element were used to simulate different components: beam elements were mainly used to simulate the axis bar, photovoltaic support purlins and pillars. Shell elements were used to simulate the photovoltaic panel.

What is the modal damping ratio of a photovoltaic support system?

Additionally, consistently low modal damping ratios were measured, ranging from 1.07 % to 2.99 %. Secondly, modal analysis of the tracking photovoltaic support system was performed using ANSYS v2022 software, resulting in the determination of structural natural frequencies and mode shapes.

What is a finite element model of tracking photovoltaic support system?

Finite element model of tracking photovoltaic support system. The tracking photovoltaic support system consisted of 10 pillars (including 1 drive pillar), one axis bar, 11 shaft rods, 52 photovoltaic panels, 54 photovoltaic support purlins, driving devices and 9 sliding bearings, and also includes the connection between the frame and its axis bar.

How many PV modules are there?

There are 25 PV modules in each span, which are divided into 5 groups. Each group has 5 PV modules, and the gap between two groups is set at 10 cm. The distance between Cable 1 and Cable 2 is 1.14 m, and the horizontal distance is 1.1 m, forming an inclined angle of 15°.
