6 FAQs about [How to reduce vibration of photovoltaic panels]

Why do photovoltaic panels vibrate?

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.

How to reduce vibrations on PV modules?

Why do photovoltaic panels vibrate in a wind tunnel?

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.

Does wind speed affect the vibration amplitude of PV panel?

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.

Why do PV panels oscillate?

The oscillations in the efficiency of the PV panel is due to the variation in vibration of the PV panel due to the existing winds, which are very strong in some weeks that causes strong vibration of the panel, and consequently immense cleaning of the panel, while in other weeks the winds are weak which can marginally vibrate the panel.

How induced vibration affects the performance of PV modules?

This high stress and deformation of PV modules lead to the generation of cracks and fractures in the PV cells. Therefore, the induced vibration can have a substantial detrimental effect on the performance and life of PV module.
