6 FAQs about [Photovoltaic support wind resistance test]

Do flexible PV modules support structures have a critical wind velocity?

Furthermore, little attentions were paid on the critical wind velocity of the flexible PV modules support structures. 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.

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-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.

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.

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.

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.
