6 FAQs about [Photovoltaic support wind load combination coefficient]

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.

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 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 direction affect the wind load on PV supports?

The wind direction angle significantly influences the wind load on PV supports. For example, distinct wind loads are produced on PV supports at varying wind direction angles. For flexible PV supports, the wind load is highly sensitive when the wind direction angle is 150°.

Can wind load models be used to design flexibly supported PV panels?

A wind load model that considered the wind-induced moment was presented based on the nonuniform distribution of wind pressure. This proposed model and its distribution coefficients can be used in designing flexibly supported PV panels. Figure 10. Installation drawing of a rigid model wind tunnel.
