4 Frequently Asked Questions about “Photovoltaic flexible support wind-resistant cable tensioning - ANA Energy Systems S.L.”
What is flexible support photovoltaic module system?
Flexible support photovoltaic module system: (a) the single-layer cable-supported photovoltaic module system, (b) the double-layer cable-supported photovoltaic module system. Recently, the author proposed the cable-truss support photovoltaic module structure system with excellent wind resistance and economic performance.
Does cable-truss support photovoltaic module structure have good wind resistance?
In this paper, a new type of cable-truss support photovoltaic module structure system with excellent wind resistance is proposed. Firstly, the superiority of the new system is proved by the aspects of static and dynamic performance. Then, the wind-vibration response is analyzed by the wind tunnel test.
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.
Do flexible PV support structures have resonant frequencies?
Modal analysis reveals that the flexible PV support structures do not experience resonant frequencies that could amplify oscillations. The analysis also provides insights into the mode shapes of these structures. An analysis of the wind-induced vibration responses of the flexible PV support structures was conducted.
