The photovoltaic panels were blown to the ground by the strong 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.

What is the wind loading over a solar PV panel system?

Jubayer and Hangan (2014) carried out 3D Reynolds-Averaged Navier–Stokes (RANS) simulations to study the wind loading over a ground mounted solar photovoltaic (PV) panel system with a 25 ° tilt angle. They found that in terms of forces and overturning moments, 45 °, 135 ° and 180 ° represents the critical wind directions.

Do solar panels receive the greatest force of headwinds?

The solar panels installed alone received the greatest force of headwinds. Moreover, as the gap between the panels increased, the magnitude decreased, and the average wind load on the structure increased as the gap ratio increased. In addition, the array had less wind load.

How does a photovoltaic array develop along the wind direction?

However, the flow of other arrays developed along the wind direction when the wind passed the SP2 to SP6 (Figs. 9 b–f). For array b, a fluctuating region similar to regular waves is formed as they flow through SP3, which is closely related to the equidistant staggered installation form of photovoltaic panels.

Does a guide plate affect the wind load on a solar panel?

However, they analyzed the effects of the guide plate in the single solar collector. Bitsuamlak et al. numerically analyzed the wind load on a solar panel array and observed the maximum wind load at an inlet angle of 180°. Thus, they proved that wind load on the 180° should be considered more importantly than other flow directions.
