Abstract: The proposed paper highlights the performance analysis of the effect of vibrations on the flexible solar panel. The vibrations have been produced by vibration generator embedded on the rear side of the flexible solar panel for testing purpose.
Strong vibrations occur when the wind speed is above a critical value. The vibrations of the windward panels are much stronger than the leeward panels. The Photovoltaic panels mainly vibrate at the first vertical and torsional mode. A suppression measure is proposed and successfully controls the wind induced vibration.
Photovoltaic panels supported by suspension cables is tested in a wind tunnel. Strong vibrations occur when the wind speed is above a critical value. The vibrations of the windward panels are much stronger than the leeward panels. The Photovoltaic panels mainly vibrate at the first vertical and torsional mode.
The wind-induced vibration caused by wind loads is one of the main reasons for the failure of PV supports, so the research focus is not only to improve the power generation efficiency of PV systems but also to reduce the wind-induced vibration of PV support structures.
The results indicate that under the boundary layer flow, the vibration amplitude of PV panel increases almost linearly with the square of wind speed, and vortex shedding induced vibration might occur at low wind speeds.
Wind-Induced Vibration For PV panels, due to the absorption of solar energy, the temperature may be too high; this is only one of the reasons for the increase in the temperature of PV panels , which also reduces the power generation efficiency of PV panels.
