Photovoltaic support wind resistance reinforcement solution

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

What are the reinforcement strategies for flexible PV support structures?

This study proposes and evaluates several reinforcement strategies for flexible PV support structures. The baseline, unreinforced flexible PV support structure is designated as F. The first reinforcement strategy involves increasing the diameter of the prestressed cables to 17.8 mm and 21.6 mm, respectively.

Does wind-induced vibration affect flexible PV supports?

Discussion The wind load is a vital load affecting PV supports, and the harm caused by wind-induced vibration due to wind loads is enormous. Aiming at the wind-induced vibration of flexible PV supports, a PV building integration technology [86, 87] was proposed to reduce the harm caused by wind vibration.

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.

What is the eccentricity of a wind-resistant PV system?

Regarding the wind-resistant design, the eccentricity of wind load has received much attention. Zhang et al. used different wind speeds to analyze the stress of PV system under 41° of tension, which showed that the wind load point deviates from that of the PV system geometry center, i.e., eccentric distribution.

Do stability cables improve wind-induced and critical wind speed of flexible PV support structure?

Liu et al. investigated on the wind-induced and critical wind speed of a 33-m-span flexible PV support structure by means of wind tunnel test on the elastic model. The effectiveness of three different types of stability cables on enhancing the critical wind speed of the flexible PV support structure was assessed.
