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.

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.

How many solar photovoltaic panels are arranged in a linear array?

Each photovoltaic panel has the same geometry with the dimension is 2.187 m × 1.102 m × 0.02 m. In computational domain, 6 solar photovoltaic panels are arranged in a linear array with an equal spacing of 1.5 m. The calculation parameters of photovoltaic panels are as shown in Table 2. Fig. 2. Solar photovoltaic array geometric model. Table 2.

What is the trailing vortex structure around a solar panel?

Fig. 11 shows the trailing vortex structure around the solar panel for different layouts. It is found that the wake vortex of the array photovoltaic panel consists of two patterns of vortex structure. One is the continuous trailing vortex from the left and right sides of the photovoltaic panel.

Do solar photovoltaic modules have different pitch angles and wind directions?

The variation of pressure, pitching moment and force coefficient of single solar photovoltaic module, and array module under different pitch angles and wind directions were studied experimentally (Zou et al., 2015; Winkelmann et al., 2020).

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.
