Photovoltaic support strip steel model

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.

Does a tracking photovoltaic support system have vibrational characteristics?

In this study, field instrumentation was used to assess the vibrational characteristics of a selected tracking photovoltaic support system. Using ANSYS software, a modal analysis and finite element model of the structure were developed and validated by comparing measured data with model predictions. Key findings are as follows.

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:

Does a tracking photovoltaic support system have finite element analysis?

In terms of finite element analysis, Wittwer et al., obtained modal parameters of the tracking photovoltaic support system with finite element analysis, and the results are similar to those of this study, indicating that the natural frequencies of the structure remain largely unchanged.

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 %.

Does tracking photovoltaic support system have a modal analysis?

While significant progress has been made by scholars in the exploration of wind pressure distribution, pulsation characteristics, and dynamic response of tracking photovoltaic support system, there is a notable gap in the literature when it comes to modal analysis of tracking photovoltaic support system.
