6 FAQs about [Surface roughness standard of photovoltaic 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 wind resistance affect surface protection in PV panels?
By analyzing the wind resistance effect in different PV panel arrays designs, a higher value of the wind resistance effect reflects a better efficiency of surface protection, indicative of a more conducive environment for the vegetation under PV panels. 4.
