6 FAQs about [The impact of photovoltaic brackets on tensioning]
Does pre-tension force affect wind-induced vibration response of flexible cable-supported photovoltaic systems?
In the current study, a series of two-way fluid-structure interaction (FSI) coupling numerical simulations are carried out to investigate the impact of the initial pre-tension force of steel cables on the wind-induced vibration response of a Flexible Cable-Supported Photovoltaic System (FCSPS).
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.
How does the tilt angle affect a solar panel?
As the solar panel tilt angle increases from 0° to 60°, the support reaction wind-induced vibration coefficient (βz_f) ranges from 1.07 to 1.67, and the displacement wind-induced vibration coefficient (βz_u) ranges from 1.70 to 1.93, showing a clear impact of the tilt angle on these coefficients.
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.
Should a photovoltaic design consider a large deformation effect?
It is recommended that practical photovoltaic engineering designs fully consider the large deformation effects of the cables.
