6 FAQs about [Graphical method for connecting the inclined beams of photovoltaic brackets]

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 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 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.

What is the tilt angle of PV modules?

According to Eq. (4), in the present study, the tilt angle of PV modules β is set to range from 0° to 30° with increments of 5°. The cable forces are constant H1 = H2 = 30 kN and H3 = 18 kN. In addition, the row spacing is set as D = 2.98 m. The self-weight of the PV modules is mainly borne by the pretension of Cable 3.

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 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.
