Why are structural and arrangement parameters important for PV power plants?

For large-scale PV power plant, the structural (inclination angle) and arrangement parameters (row spacing and column spacing) were important for improving power generation efficiency and sustaining the local environment and land use.

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.

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).

Which PV panel array has the highest drag and lift forces?

The results revealed that the foremost row of PV panel arrays experienced the highest drag and lift forces, while the maximum overturning moment occurred under a wind direction of 45°.

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.

Are photovoltaic panels safe during extreme wind?

By incorporating the evaluation of surface shear stress corresponding to the extreme wind velocity (Appendix A), it can be inferred that the photovoltaic (PV) panels deployed at the study site exhibit an adequate level of safety during conditions of extreme wind. Fig. 14.
