Through processing and analyzing the measured modal data of the tracking photovoltaic support system with Donghua software, the dynamic characteristic parameters of the tracking photovoltaic support system could be obtained, including frequencies, vibration modes and damping ratio.
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.
As the current study uses mounting systems with horizontal single-axis tracker configuration, the shading study between P V modules is different, and the determination of the solar tracking algorithm was not the subject of the previous study.
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.
Recent research indicates that the dynamic characteristics of tracking photovoltaic support system, namely inertia, damping, and stiffness, significantly influence the tracking photovoltaic support system's ability to respond to wind-induced loads, affecting its stability, reliability, and overall performance , .
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.
