The photovoltaic bracket was blown down by the wind

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 does wind pressure affect a front-row photovoltaic panel?

Pressure distribution along the solar panel profile line. In addition to SP1 being subjected to the main wind load, the wind pressure attenuation of the rest of array a is obvious. Hence, the structure needs to focus on strengthening the structural strength of the front-row photovoltaic panels.

Why is wind load important for a Floating photovoltaic system?

The wind load is especially important for floating photovoltaic systems. Fig. 2, a floating photovoltaic system is above the sea or a lake. A floating body supports the solar panels by the buoyancy force, which is balanced with the weights of the solar panel and itself.

Does wind direction affect a photovoltaic panel?

And the lift coefficient of the photovoltaic panel in the back two rows is also significantly reduced. In choi 's research, the drag and lift coefficients of PV panels are significantly higher than those of other attack angles when the wind direction is 180° (Choi et al., 2021).

What happens if wind impinged the first row of solar panels?

When the wind flow impinged the first row of solar panels, it separated to go above and under the panels. This phenomenon was observed for different TIs. Behind the first row of solar panels, the wind separated, and a recirculating flow developed. As the wind passed the second to tenth rows, the flow developed along the wind direction.

Can solar photovoltaic arrays balance wind load and buoyancy?

And a solar photovoltaic array layout that can balance wind load and buoyancy is proposed to achieve the purpose of preventing the floating structure from sinking or overturning. 3.1. Flow characteristics Fig. 9 shows the wind speed distributions at monitoring surface 1 for different layouts.
