Guanling photovoltaic panels were blown over by strong winds

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.

Does PV panel installation mode affect wind load?

The influence of PV panel installation mode on the wind load of PV panel array model at high Reynolds number (Re =1.3 × 10 5) was studied by a wind tunnel experiment, including PV panel inclination, wind direction, and longitudinal panel spacing of photovoltaic panels (Yemenici, 2020).

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.

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.

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.

How do wind loads and buoyancy force affect solar panels?

Balancing the wind loads and buoyancy force is important to prevent floating structures from sinking or overturning. In this study, numerical simulations were performed to predict the wind loads on solar panels at various turbulence intensities (0.1–0.3) and wind speeds (35–75 m/s).
