6 FAQs about [Photovoltaic support down pressure]
How does wind pressure affect a flexible PV support structure?
When the flexible PV support structure is subjected to wind pressure, the maximum of mean vertical displacement occurs in the first rows at high wind speeds. The shielding effect greatly affects the wind-induced response of flexible PV support structure at α = 20°.
How to reduce wind load of PV support structure?
It is also necessary to reasonably increase the template gap and reduce the ground clearance in order to reduce the wind load of the PV support structure, enhance the wind resistance of the PV support structure, and improve the safety and reliability of the PV support structure. 2.7. Other Factors
What is the wind load of a PV support?
The wind load is the most significant load when designing a PV support; thus, its value and calculation should be investigated. Different countries have their own specifications and, consequently, equations for the wind loads of PV supports.
How to design a PV support system?
When designing PV support systems, the wind load is the primary load to consider for PV power generation. The amount of the PV wind load is influenced by various elements, such as the panel inclination angle, wind direction angle, body type coefficient, geometric scale, shielding effect, and template gap.
How does wind pressure affect a PV module?
The wind pressure distribution along the surface of the PV module array exhibits a notable gradient, with the wind pressure gradually decreasing in the direction of the wind. When α = 20°, the mean wind pressure coefficient of R2 is nearly the same as that of R11 and R12, which is different from α = 10°.
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.
