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°.

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.

How does wind load affect photovoltaic panels?

The wind load on the photovoltaic panel array is sensitive to wind speed, wind direction, turbulence intensity, and the parameters of the solar photovoltaic panel structure. Many researchers have carried out experimental and numerical simulation analyses on the wind load of photovoltaic panel arrays. Table 1.

How to calculate wind speed of a PV plant?

Step 1: Calculate the fundamental wind speed ( V) of the project as per the location of the Project (Refer figure 1). TABLE 1). Step 3: Calculate the Terrain factor ( K) based on location and height of Buildings (Refer TABLE 2). Step 3a. Select the Category as per the location of PV plant. Then the structure comes under category 3.

How to study wind load of photovoltaic panel arrays?

Many researchers have carried out experimental and numerical simulation analyses on the wind load of photovoltaic panel arrays. Table 1. Features of different offshore floating photovoltaics. The boundary-layer wind tunnels (BLWTs) are a common physical experiment method used in the study of photovoltaic wind load.

Why do wind-resistant PV modules have a small vibration amplitude?

Due to the wind-resistant anchor cables setting in both the windward and leeward zones, the vibration amplitude of the PV modules near the edge rows is significantly smaller than that of the middle rows when the structure is subjected to wind suction.
