Photovoltaic support prestressing

4 FAQs about Photovoltaic support prestressing

What is a flexible photovoltaic support?

In recent years, a flexible photovoltaic support, which uses prestressed cables to fix and support the photovoltaic module and which transmits the upper load to the foundation through a substructure on both sides of the cable, has gradually received extensive attention in the engineering field. An example of this is shown in Figure 1 b.

Can a flexible photovoltaic module support system be used in long-span environments?

The flexible photovoltaic module support system, which can be used in complex and long-span environments, has been widely studied and applied in recent years. In this study, the wind-induced vibration characteristics and the suppression measures of a 35-meter-span cable-truss support photovoltaic module system array are studied.

How to evaluate a flexible photovoltaic support structure?

For the flexible photovoltaic support structure, the evaluation criteria of structural performance should be established according to its working characteristics, and its “shape” and “state” under prestress and load should be analyzed and compared, so as to obtain the optimal initial state under the premise of economy and functional requirements.

Does a flexible photovoltaic module support system have a strong wind load?

Du et al., Ma et al., and Wang et al. also studied the wind load characteristics of the single-layer cable flexible photovoltaic support system with a span of about 20 m and concluded that this type of flexible photovoltaic module support system had weak wind resistance and obvious wind-induced vibration, , (Fig. 1 a).
