6 FAQs about [The inclined beam of the photovoltaic bracket has large deformation]

Should a photovoltaic design consider a large deformation effect?

It is recommended that practical photovoltaic engineering designs fully consider the large deformation effects of the cables.

Is structural deformation increasing linearly when stress is building inside a PV panel?

In Fig. 12 a clear portrait of stress vs. structural deformation has been plotted to show that how structural deformation is increasing linearly when stress is building inside a PV panel. Overall view of maximum internal stress vs. maximum total deformation when the wind speed is varying from 10 to 260 km/h

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 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 structural static characteristics of a new PV system?

The structural static characteristics of the new PV system under self-weight, static wind load, snow load and their combination effect are further studied according to the Chinese design codes (Load Code For The Design Of Building Structures GB 2009-2012 and Code For Design Of Photovoltaic Power Station GB 50797-2012).

What is the inflection point of a cable-supported PV system?

When the upward vertical displacement is less than 0.0639 m, the force first counteracts the self-weight of the cables and PV modules. Therefore, there is an inflection point at 0.0639 m. For the new cable-supported PV system, the lateral stiffness is much higher than the vertical stiffness.
