6 FAQs about [Photovoltaic support structure system drawings]
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 %.
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 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.
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 photovoltaic support systems track wind pressure and pulsation?
Currently, most existing literature on tracking photovoltaic support systems mainly focuses on wind tunnel experiments and numerical simulations regarding wind pressure and pulsation characteristics. There is limited research that utilizes field modal testing to obtain dynamic characteristics.
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.
