6 FAQs about [Calculation of wind pressure resistance of photovoltaic bracket]

What is the basic wind pressure of a PV structure?

In a site with category B, 25 years return period, and a height of 10 m, the basic wind pressure of the PV structure is w0 = 0.45 kN/m 2. and the wind pressure height coefficient μz is 1.0. Then Eq. (6) is used to compare the test results with the code.

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

How does wind pressure affect a PV module?

The wind pressure distribution along the surface of the PV module array exhibits a notable gradient, with the wind pressure gradually decreasing in the direction of the wind. When α = 20°, the mean wind pressure coefficient of R2 is nearly the same as that of R11 and R12, which is different from α = 10°.

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°.

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.
