6 FAQs about [Photovoltaic support purlin force diagram]

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 is a tracking photovoltaic support system?

The tracking photovoltaic support system ( Fig. 1) is mainly composed of an axis bar, PV support purlins, pillars (including one driving pillar in the middle and nine other non-driving pillars), sliding bearings and a driving device. The axis bar is composed of 11 shaft rods. Photovoltaic panels are installed on the photovoltaic support purlins.

What is a finite element model of tracking photovoltaic support system?

Finite element model of tracking photovoltaic support system. 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.

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 %.

What are the mechanical properties of a tracking photovoltaic support system?

In terms of the mechanical properties of the actual components of the tracking photovoltaic support system, the bar element and shell element were used to simulate different components: beam elements were mainly used to simulate the axis bar, photovoltaic support purlins and pillars. Shell elements were used to simulate the photovoltaic panel.

How to evaluate the dynamic response of tracking photovoltaic support system?

To effectively evaluate the dynamic response of tracking photovoltaic support system, it is essential to perform a tracking photovoltaic support systematic modal analysis that enables a comprehensive understanding of the inherent dynamic characteristics of the structures.
