6 FAQs about [What does the bottom beam of a photovoltaic support mean ]

What is cable-supported photovoltaic (PV)?

Cable-supported photovoltaic (PV) modules have been proposed to replace traditional beam-supported PV modules. The new system uses suspension cables to bear the loads of the PV modules and therefore has the characteristics of a long span, light weight, strong load capacity, and adaptability to complex terrains.

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 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 PV support structure?

Support structures are the foundation of PV modules and directly affect the operational safety and construction investment of PV power plants. A good PV support structure can significantly reduce construction and maintenance costs. In addition, PV modules are susceptible to turbulence and wind gusts, so wind load is the control load of PV modules.

What is a photovoltaic module (PV)?

The photovoltaic modules (PV) are installed in the solar radiations with sufficient tilted angles on the ground or rooftop to provide electrical energy. The overall conversion efficiency of this technology is very less due to the material properties which are utilized for the PV cells.

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.
