6 FAQs about [Horizontal force of photovoltaic support]

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.

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.
