6 FAQs about [Calculation of cable-suspended photovoltaic support]

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 cable-supported photovoltaic system (CSPs)?

Cable-supported photovoltaic systems (CSPSs) are a new technology for supporting structures that have broad application prospects owing to their cost-effectiveness, light weight, large span, high headroom, few pile foundations, short construction period, and symbiosis with fisheries and farms.

How many cables does a PV system use?

However, most of the traditional cable-supported PV systems use only two cables to support the PV modules. The settlement of the support cables due to self-weight of PV modules always reduces their power generation efficiency. Therefore, it is necessary to make a reasonable design to flatten the structures.

How does a cable-supported PV system change structural parameters?

Parametric analyses The new cable-supported PV system often changes structural parameters to adapt to different geographic environments, such as changing the row spacing to obtain different amounts of daylight or enlarging the cable diameter to enhance the bearing capacity of the structure.
