6 FAQs about [Photovoltaic support wind pressure and snow pressure]

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 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°.

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 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

How does wind load affect PV panel support?

2. Influencing Factors of Wind Load of PV Panel Support 2.1. Panel Inclination Angle The angle β between the PV panel and the horizontal plane is called the panel inclination (Figure 3). Because of the PV panel’s varying inclination angle, a PV power generation system’s wind load varies, impacting the system’s power generation efficiency. Figure 3.

How does wind load affect PV power generation?

A wind load accelerates the cooling of PV panels, thereby reducing the cell’s temperature and increasing the power generation efficiency for PV power generation. However, the PV panel generates wind-induced vibration due to the wind load, which can damage the system (Figure 12).
