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.

Why do photovoltaic panels have similar vortex structures?

For array b, a large amount of the central vortex shedding periodically occurs between the SP3 and SP4, and the vortex column on both sides of the photovoltaic panel is deformed by the influence of the recirculation region. Array c and e have similar vortex structures due to the high similarity of the overall structure.

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.

Should PV panels be arranged in parallel?

Thus, it is very unfavorable for the structure of the PV panel arrays arranged in parallel due to the variable wind direction at sea. In this regard, the staggered or symmetrical arrangement may be a feasible measure.

How does a photovoltaic panel arrangement affect the lift?

Compared with resistance, the lift is more sensitive to photovoltaic panel arrangement, and the primary influence is the lift direction (Photovoltaic panel installation direction). The drag and lift of the mutually parallel panels all show the same trend of gradual increase or decrease with increasing the pitch angel of the platform.

What is a photovoltaic vortex?

One is the continuous trailing vortex from the left and right sides of the photovoltaic panel. The other is the vortex street generated on the upper surface of the photovoltaic panel is truncated and broken into a small-scale vortex shedding from the center due to the recirculation flow behind the photovoltaic panel.
