Is the default wind direction perpendicular to PV panels?

The default wind direction was perpendicular to PV panels. In the present study, the left and right boundaries were set as symmetry planes, which were computationally efficient, and high-resolution simulations were maintained in the computational domain.

Which inclination angle is best for PV panels?

According to the wind resistance effect, the PV panel array with an inclination angle of 35°, a column spacing of 0 m, and a row spacing of 3 m had the best efficiency of wind block. As the increase of ambient wind velocity, the inclination angle should be reduced to rise the resistance efficiency and avoid possible damage to PV panels.

How do PV panels affect wind resistance and wind load?

Wind resistance effect and the wind load As mentioned previously, the presence of PV panel arrays increases the surface roughness and weakens the shear force. The shear stress and relative wind velocity (u r) are commonly used to evaluate the efficiency of wind barriers and breaks (Fang et al., 2018; Guo et al., 2021).

Does oblique wind affect PV panels?

The simulations indicate that, under identical wind speeds, the PV panel arrays exhibit superior capacity in mitigating the impact of oblique wind directions (45° and 135°), particularly noticeable at the forefront of the PV panel.

Can PV panels reduce wind speed under high wind velocity?

The results indicated that the PV panel arrays could effectively reduce wind speed in downwind areas under high wind velocity, while its wind resistance effect was not as good as that under medium or low wind velocity. The PV panels were lifted above the ground, which caused less wind resistance under a high wind velocity. Fig. 15.

What is the optimal configuration for a photovoltaic panel array?

Under wind velocities of 2 m/s and 4 m/s, the optimal configuration for photovoltaic (PV) panel arrays was observed to possess an inclination angle of 35°, a column spacing of 0 m, and a row spacing of 3 m (S9), exhibiting the highest φ value indicative of wind resistance efficiency surpassing 0.64.
