6 FAQs about [Distributed photovoltaic support wind resistance]
Why is wind resistance important in PV power generation systems?
Therefore, wind resistance is essential for a safe, durable, and sustainable PV power generation system. There are three modes of support in PV power generation systems: fixed , flexible , and floating [4, 5]. Fixed PV supports are structures with the same rear position and angle.
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.
Are photovoltaic power generation systems vulnerable to wind loads?
(1) Background: As environmental issues gain more attention, switching from conventional energy has become a recurring theme. This has led to the widespread development of photovoltaic (PV) power generation systems. PV supports, which support PV power generation systems, are extremely vulnerable to wind loads.
How wind induced vibration response of flexible PV support structure?
Aeroelastic model wind tunnel tests The wind-induced vibration response of flexible PV support structure under different cases was studied by using aeroelastic model for wind tunnel test, including different tilt angles of PV modules, different initial force of cables, and different wind speeds.
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.
