How to solve the displacement of photovoltaic bracket

Why is plate deflection important in BIPV design?

That shape of plate deflection agrees well with the boundary condition. Moreover, it denotes that the maximum deflections of PV panel with two boundary conditions are both produced at the middle position of the plate, so it should be considered very carefully in future BIPV design work. Fig. 23.

What is a fixed adjustable photovoltaic support structure?

In order to respond to the national goal of “carbon neutralization” and make more rational and effective use of photovoltaic resources, combined with the actual photovoltaic substation project, a fixed adjustable photovoltaic support structure design is designed.

How does plate stress affect a PV panel?

That shape of plate stress also agrees well with the boundary condition. Moreover, the maximum stress of PV panel with two boundary conditions are both produced at the middle position of the plate. The middle position is a key position to decide the damage of the whole PV panel.

What is a new cable supported PV structure?

New cable supported PV structures: (a) front view of one span of new PV modules; (b) cross-section of three cables anchored to the beam; (c) cross-section of two different sizes of triangle brackets. The system fully utilizes the strong tension ability of cables and improves the safety of the structure.

How is a PV module fixed?

The PV module is fixed on Cables 1 and 2 by using back-fasteners. The maximum stress is calculated as 6.60 × 10 7 N/m 2 at the four nodes connecting the load-bearing cables and the PV module. Similar results are observed in Case 180°, as shown in Fig. 13 (b).

How are PV panels connected?

The spans are connected by struts, with the support cables having a height of 4.75 m, directly supporting the PV panels. The wind-resistant cables are 4 m high and are connected to the lower ends of the struts. The end support beams are 4 m high, with tie rods connected to the end support beams at a 45° angle, each measuring 5.657 m in length.
