6 FAQs about [Photovoltaic support wind pressure coefficient standard]

What is the wind vibration coefficient of flexible PV support structure?

The wind vibration coefficients in different zones under the wind pressure or wind suction are mostly between 2.0 and 2.15. Compared with the experimental results, the current Chinese national standards are relatively conservative in the equivalent static wind loads of flexible PV support structure. 1. Introduction

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 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 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 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 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°.
