About Photovoltaic support wind resistance contract
(Liu et al., 2023) concluded that the central stability plate has no effect on the improvement of wind resistance performance, and the critical wind speed of the 33m-span cable support photovoltaic module system in a uniform wind field was only about 18.5 m/s. Meanwhile, they proposed effective measures against critical instability wind speed.

Wind-induced response of a type of flexible PV modules support structure with a span of 33 m was investigated by using wind tunnel tests based on elastic test model, and the effectiveness of three types of stability cables on reducing wind-induced vibration of the flexible PV modules support structures were carefully examined.
Wind often damages PV supports. The wind load is the most significant load considered while designing a PV support . Therefore, wind resistance is essential for a safe and durable PV power generation system.
Boundary layer wind tunnel tests were performed to determine wind loads over ground mounted photovoltaic modules, considering two situations: stand-alone and forming an array of panels. Several wind directions and inclinations of the photovoltaic modules were taken into account in order to detect possible wind load combinations that may lead to .
This study investigates the wind loads acting on ground mounted photovoltaic panels and the support structures thereof with wind tunnel experiments. As a result, observed at the northernmost panel is the minimum wind force coefficient to which the corresponding wind load exceeds the wind load specified in IEC 61215. On the

6 FAQs about [Photovoltaic support wind resistance contract]
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.
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.
Do flexible PV support structures deflection more sensitive to fluctuating wind loads?
This suggests that the deflection of the flexible PV support structure is more sensitive to fluctuating wind loads compared to the axial force. Considering the safety of flexible PV support structures, it is reasonable to use the displacement wind-vibration coefficient rather than the load wind-vibration coefficient.
Do stability cables increase critical wind velocity of flexible PV modules support structures?
Wind-induced response and critical wind velocity of a 33-m-span flexible PV modules support structure was investigated by using wind tunnel tests based on elastic test model, and the effectiveness of three types of stability cables on enhancing the critical wind velocity of the flexible PV modules support structures was carefully examined.
Does wind-induced response and critical wind velocity affect a flexible PV support structure?
In this study, wind-induced response and critical wind velocity of a 33-m-span flexible PV support structure was experimentally studied by using a non-contact video displacement measuring system. An elastic test model of the flexible PV modules support structure was firstly designed and manufactured.
