Standard load value of photovoltaic flexible bracket

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.

For flexible PV brackets, the allowable deflection value adopted in current engineering practice is 1/100 of the span length [32]. To ensure the safety of PV modules under extreme static conditions, a detailed analysis of a series of extreme scenarios will be conducted.

In this Perspective, Fukuda et al. outline standards and best practices for measuring and reporting photovoltaic performance under bending stresses, strain and load orientation.

The main load borne by photovoltaic modules and support is wind load [2] ~ [9]. There is also a snow load in the northern region. Compared with a rigid support, flexible photovoltaic support is more sensitive to wind load and has large deformation under the static action of snow load.

The static calculation formula obtained in the paper is simple and accurate, and the vertical tangent stiffness of equilibrium state has clear physical significance, which can provide reference for static analysis and structural design of flexible photovoltaic support.

6 FAQs about [Standard load value of photovoltaic flexible bracket]

How safe are flexible PV brackets under extreme operating conditions?

Safety Analysis under Extreme Operating Conditions For flexible PV brackets, the allowable deflection value adopted in current engineering practice is 1/100 of the span length . To ensure the safety of PV modules under extreme static conditions, a detailed analysis of a series of extreme scenarios will be conducted.

What is cable-supported photovoltaic (PV)?

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 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.

Do flexible PV support structures deflection more sensitive to fluctuating wind loads?

This suggests that the deflection of the flexible PV support structure is more sensitive to fluctuating wind loads compared to the axial force. Considering the safety of flexible PV support structures, it is reasonable to use the displacement wind-vibration coefficient rather than the load wind-vibration coefficient.

What is a flexible PV mounting structure?

Flexible PV Mounting Structure Geometric Model The constructed flexible PV support model consists of six spans, each with a span of 2 m. The spans are connected by struts, with the support cables having a height of 4.75 m, directly supporting the PV panels. The wind-resistant cables are 4 m high and are connected to the lower ends of the struts.
