6 FAQs about [Photovoltaic support special hole punch model]

What are photovoltaic structures?

Photovoltaic structures represent the supports for photovoltaic panels. These photovoltaic panels can be with an aluminum frame with a thickness of between 30 mm and 45 mm, or photovoltaic panels with double glass without frames. Below are our structure systems available for ground-mounted power plants:

How stiff is a tracking photovoltaic support system?

Because the support structure of the tracking photovoltaic support system has a long extension length and the components are D-shaped hollow steel pipes, the overall stiffness of the structure was found to be low, and the first three natural frequencies were between 2.934 and 4.921.

How many pillars does a photovoltaic support system have?

The tracking photovoltaic support system consisted of 10 pillars (including 1 drive pillar), one axis bar, 11 shaft rods, 52 photovoltaic panels, 54 photovoltaic support purlins, driving devices and 9 sliding bearings, and also includes the connection between the frame and its axis bar. Total length was 60.49 m, as shown in Fig. 8.

What are the dynamic characteristics of photovoltaic support systems?

Key findings are as follows. Dynamic characteristics of tracking photovoltaic support systems obtained through field modal testing at various inclinations, revealing three torsional modes within the 2.9–5.0 Hz frequency range, accompanied by relatively small modal damping ratios ranging from 1.07 % to 2.99 %.

Why is a photovoltaic support system prone to torsional vibrations?

Due to the lower natural frequencies and torsional stiffness, the system is susceptible to significant torsional vibrations induced by wind. Currently, most existing literature on tracking photovoltaic support systems mainly focuses on wind tunnel experiments and numerical simulations regarding wind pressure and pulsation characteristics.

What is the modal damping ratio of a photovoltaic support system?

Additionally, consistently low modal damping ratios were measured, ranging from 1.07 % to 2.99 %. Secondly, modal analysis of the tracking photovoltaic support system was performed using ANSYS v2022 software, resulting in the determination of structural natural frequencies and mode shapes.
