Photovoltaic panel support damper

Do large solar arrays need vibration damping?

Hence, vibration damping for large solar arrays is necessary. The HST vibration suppression is a successful example of passive control applications. 2 However, its damper was in a series damping mode and had a trade-off between the damper stiffness and damping performance.

Does Vanguard 1p have bidirectional dampers?

Therefore, Vanguard 1P comes with bidirectional dampers. The wind tunnel test results from CPP show that Vanguard 1P can reach a critical instability wind speed of up to 60m/s or more at the stow position, which is sufficient to meet the wind resistance requirements for trackers in most areas.

What is a passive vibration damping device for a multi-panel solar array?

A novel passive vibration damping device for the multi-panel solar array is presented. The device is lockable and located near the solar array root hinge to increase the modal damping ratio in the first bending vibration mode without reducing the fundamental frequency.

What is the damping law of a solar panel?

The damping law is F = CV, where F is the damping force, C is the damping coefficient, and V is the relative velocity between the ends of the damper. The solar panel is honeycomb sandwich structure with length × width × thickness of 2258 mm × 1826 mm × 30 mm for every piece.

Can a damping element damp a solar array?

Practically, most modal strain of the deployed solar array’s first vibration mode is concentrated at the root. Therefore, attaching damping element to the root can well damp the structure.

Why do you need a hydraulic damper?

High quality and long service life: The hydraulic dampers of the SOL family can be used to provide support for minimizing the negative effects of weather anomalies (i.e. vortex shedding, wind galloping) to PV Solar Tracking systems. Its ...
