Abstract

In order to investigate the influence of sloping landform on the wind-induced vibration characteristics of solar panels, this study conducted a numerical simulation of the wind-induced response of a solar array based on FSI（fluid structure interface）. The flow characteristics of the solar array and the modal response of the solar panels were analyzed, and the wind-induced vibration characteristics of solar panels located on slopes with different inclinations at different heights and spacings were revealed. The results show that： 1） The slope causes airflow blockage, which increases the displacement amplitude of the solar panels, and also reduces the shielding effect of the front-row solar panels on the rear-row solar panels; 2） From the flow characteristics, it can be seen that the first solar panel at the windward edge generates a vortex, which detaches in the rear area, making the flow field in front of the second solar panel complicated, while the flow field around the third solar panel is relatively stable, indicating that the more downstream the solar panel is, the less it is affected by the flow field; 3） The vibration of the solar panels is dominated by low-order modes, and the slope has a significant impact on the vibration of the rear-row solar panels; 4） Increasing the spacing has an impact on the vibration response of the solar array located on the slope, and the impact becomes more significant with the increase of the slope angle; 5） Increasing the height of the solar array on the slope, the displacement amplitude of the first solar panel changes significantly, while the impact on the other two solar panels is relatively small.
