Prestressed zipper photovoltaic bracket

Why are pre-stressed flexible cable-supported photovoltaic systems becoming more popular?

With the increasing adoption of mountainous photovoltaic installations, pre-stressed flexible cable-supported photovoltaic (PV) systems (FCSPSs) are becoming increasingly popular in large-scale solar power plants due to their evident adaptability to sloping terrain. The wind-induced deformation of FCSPSs significantly influences the wind field.

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 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.

Why are flexible PV mounting systems important?

Traditional rigid photovoltaic (PV) support structures exhibit several limitations during operational deployment. Therefore, flexible PV mounting systems have been developed. These flexible PV supports, characterized by their heightened sensitivity to wind loading, necessitate a thorough analysis of their static and dynamic responses.

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 new cable-supported photovoltaic system?

A new cable-supported photovoltaic system is proposed. 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.
