U21C Solar Tracker Damper Vibration Damping Buffer Device for Wind Disturbance Protection

U21C Solar Tracker Damper

The TOMUU U21C solar tracker damper is designed to slow and dampen tracker movement under wind gusts and other external disturbances, helping reduce excessive movement of photovoltaic tracker structures.

U21C is available with two force and speed configurations, providing different options for tracker structures, mounting conditions and project requirements.

Two Force & Speed Configurations

U21C provides two standard performance configurations. The appropriate version can be selected according to the force and movement requirements of the tracker system.

U21C Solar Damper Specifications

Dimensions & Installation

U21C stroke, fully extended length and fully retracted length are determined by the tracker geometry and mounting position.

The standard front-end and rear-end connections use Ø26.7mm mounting holes. Other mounting-hole configurations can be evaluated when required by the tracker structure.

Typical Solar Tracker Applications

• Utility-scale photovoltaic tracking systems
• Single-axis solar trackers
• Dual-axis solar tracking structures
• Solar installations exposed to wind disturbance
• Ground-mounted photovoltaic power plants

Solar Tracker Project Experience

TOMUU supplies actuator and damper solutions for utility-scale photovoltaic tracking projects. In tracker systems using both components, the actuator drives and positions the structure, while the damper helps control unwanted movement caused by wind and other external disturbances.

One example is the Samarkand 1 Solar PV + BESS project, where TOMUU supplied U20 Series industrial linear actuators and U21 Series dampers for the solar tracking application.

Why TOMUU for U21C Solar Dampers?

TOMUU has supported solar tracking applications since 2017, with actuator solutions used in more than 57GW of solar projects worldwide.

The U21C extends TOMUU's solar tracker component range with two defined force and speed configurations, supporting different mechanical and installation requirements within tracker projects.

For U21C selection, TOMUU evaluates the required restoring and compressive force, movement speed, stroke, mounting dimensions and tracker structure together.

Manufacturing for Solar Tracker Components

TOMUU supports the production of linear actuators and dampers for solar tracking applications, with manufacturing processes covering assembly, inspection and product testing.

U21C Testing & Environmental Specifications

U21C is specified with IP66 protection, an operating temperature range of -40°C to +65°C, and an 840-hour salt spray test for outdoor solar tracking applications.
