6 FAQs about [Photovoltaic support wind resistance performance]
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.
Are photovoltaic power generation systems vulnerable to wind loads?
(1) Background: As environmental issues gain more attention, switching from conventional energy has become a recurring theme. This has led to the widespread development of photovoltaic (PV) power generation systems. PV supports, which support PV power generation systems, are extremely vulnerable to wind loads.
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.
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
Are flexible PV supports sensitive to wind?
Flexible PV supports are highly sensitive to fluctuating wind, and thus numerous scholars have studied the wind-induced response of flexible PV supports.
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.
