About How strong is the tension of the flexible photovoltaic bracket

Compared with a rigid support, flexible photovoltaic support is more sensitive to wind load and has large deformation under the static action of snow load. In addition, it has been found in the project that the damage rate of photovoltaic components on the flexible support is far higher than that on the fixed support.

The suspension cable structure with small sag-span ratio (less than 1/30) is adopted in the flexible photovoltaic support, and it has strong geometric nonlinearity.

The system fully utilizes the strong tension ability of cables and improves the safety of the structure. It is convenient to adjust the tilt angle of the PV modules to ensure the maximum lighting area.

A DAS Solar flexible bracket counteracts high structural loads by applying pre-tension to a steel cable, allowing it to span between 20m and 40m by controlling cable strength and deformation. Construction challenges associated with traversing slopes and ravines faced by conventional photovoltaic bracket is effectively addressed by a maximum .

6 FAQs about [How strong is the tension of the flexible photovoltaic bracket ]

Do flexible PV support structures deflection more sensitive to fluctuating wind loads?

This suggests that the deflection of the flexible PV support structure is more sensitive to fluctuating wind loads compared to the axial force. Considering the safety of flexible PV support structures, it is reasonable to use the displacement wind-vibration coefficient rather than the load wind-vibration coefficient.

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.

What is a flexible PV support structure?

The baseline, unreinforced flexible PV support structure is designated as F. The first reinforcement strategy involves increasing the diameter of the prestressed cables to 17.8 mm and 21.6 mm, respectively. These configurations are named F1-1 and F1-2 for ease of comparison.

Do flexible PV support structures have resonant frequencies?

Modal analysis reveals that the flexible PV support structures do not experience resonant frequencies that could amplify oscillations. The analysis also provides insights into the mode shapes of these structures. An analysis of the wind-induced vibration responses of the flexible PV support structures was conducted.

What is a flexible PV mounting structure?

Flexible PV Mounting Structure Geometric Model The constructed flexible PV support model consists of six spans, each with a span of 2 m. 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.

Does a flexible PV support structure exhibit a consistent response trend?

However, for mid-span acceleration, the wind suction condition results in greater values than the wind-pressure condition. Overall, it can be concluded that the flexible PV support structure exhibits a consistent response trend under both wind-suction and wind-pressure conditions. Figure 10.
