4 FAQs about [No lateral displacement of photovoltaic support column]
Do flexible photovoltaic support systems suffer from aerodynamic instability?
Flexible photovoltaic (PV) support systems have low stiffness, low damping, and may suffer from aerodynamic instability, especially fluttering, under wind loads. Reliable structural modal parameters are essential for studying aerodynamic instability.
Does panel inclination affect flexible PV support structure?
These findings indicate that under the influence of mean wind loads, a more minor panel inclination angle results in reduced displacement values for the flexible PV support structure, ultimately minimizing the detrimental effects of wind-induced responses on the flexibility and stability of the PV support system.
Does a flexible PV support structure respond to wind load?
As a result, the actual response of the flexible PV support structure under severe wind conditions may be underestimated in analysis. Therefore, the safety and wind-induced response of the flexible PV support structure under fluctuating wind load should be considered and compared with its response under mean wind load.
How to reduce vertical displacement of PV modules?
Therefore, it is necessary to make a reasonable design to flatten the structures. Recently, the authors (He et al., 2020) proposed a new cable-supported PV system using three cables and four triangle brackets to form an inverted arch to reduce the vertical displacement of the PV modules.
