6 FAQs about [Photovoltaic bracket wind resistance design]
Why do PV modules have wind-resistant anchor cables?
Due to the wind-resistant anchor cables, which are anchored to the foundation and set in both the windward and leeward zones, the vibration of the PV modules and load-bearing cables under wind suction is suppressed.
How to reduce wind load of PV support structure?
It is also necessary to reasonably increase the template gap and reduce the ground clearance in order to reduce the wind load of the PV support structure, enhance the wind resistance of the PV support structure, and improve the safety and reliability of the PV support structure. 2.7. Other Factors
Why is wind resistance important in PV power generation systems?
Therefore, wind resistance is essential for a safe, durable, and sustainable PV power generation system. There are three modes of support in PV power generation systems: fixed , flexible , and floating [4, 5]. Fixed PV supports are structures with the same rear position and angle.
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. Results and discussion 4.1. CFD model validation
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).
What are the main wind load issues associated with PV supports?
Making full use of the previous research results, the following are the main wind load issues associated with the three types of PV supports: (1) the factors affecting the wind loads of PV supports—the main factors are shown in Figure 2; (2) the wind-induced vibration of PV supports; (3) the value and calculation of the wind load of a PV support.
