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 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.

Where is the highest wind pressure coefficient observed in a PV array?

Under positive wind pressure, the highest mean wind pressure coefficient is observed in the first row of the windward zone. Except at tilt angle α = 10°, the PV array shows a noticeable shielding effect starting from the second row in the windward zone. Wind pressure variations are more pronounced in the windward zone compared to the leeward zone.

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 pressure coefficient of a rear PV module?

As the tilt angle increases, the rear PV modules stabilize. Specifically, when α is 10°, 20°, and 30° in the side span, the mean wind pressure coefficient for R5 to R8 ranges from −0.7 to −0.5, −0.62 to −0.5, and −0.76 to −0.52, respectively.
