Vertical tracking photovoltaic bracket design

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.

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.

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.

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.

Can a tracking photovoltaic support system reduce wind-induced vibration?

Finite element analysis also showed a slight increase in natural frequencies with increasing inclination angle, which was in good agreement. This suggests that the design of the tracking photovoltaic support system can be optimized to reduce the impact of wind-induced vibration on the tracking photovoltaic support system.

How are horizontal single-axis solar trackers distributed in photovoltaic plants?

This study presents a methodology for estimating the optimal distribution of horizontal single-axis solar trackers in photovoltaic plants. Specifically, the methodology starts with the design of the inter-row spacing to avoid shading between modules, and the determination of the operating periods for each time of the day.
