Specialized damping technology designed for solar tracking systems to ensure optimal performance and longevity

What is a Solar Damper?

A solar tracker damper is a hydraulic damping device engineered specifically for solar tracking systems. It provides controlled resistance to suppress vibrations and oscillations caused by wind forces, ensuring stable and precise positioning of solar panels. Key functions include stabilizing the panel angle, buffering external impact, protecting the slew drive during stow events, and suppressing vortex-induced vibration and torsional galloping.

Solar Damper Product

Key Functions

Fixed Panel Angle

Maximizes solar capture for both fixed and tracking solar panels (stabilizes trackers).

Buffer External Impact

Absorbs energy during high winds, earthquakes, or mechanical shocks to prevent damage to panels and mounting structures.

Drive-Lock & Stow Stability

Simplifies site-wide inspection by providing rigid positioning when the tracker enters its maximum stow angle (60°), safeguarding the slew drive from back-driving and high-torque mechanical fatigue during wind-stow events.

Enhanced Stability

Reduces wind-induced vibrations and mechanical fatigue, improving system stability and reliability.

Key Performance Indicators

Wind Load Resistance

Engineered to withstand extreme hurricane-level wind forces and prevent tracker twisting.

Temperature Range

Maintains consistent hydraulic damping performance across extreme desert heat and freezing conditions.

Long Lifespan

2 million cycle lifetime

Solar Damper Sizing & Selection Guide

Match the right damper to your tracker in three steps: size the damping force to the torque tube length and wind load, confirm the stroke against your tracker's rotation range, and choose single- or bi-directional hydraulic damping for your configuration.

Solar Damper Applications

Versatile solutions for various solar tracking system configurations

Single-Axis Trackers

Single-Axis Trackers

Optimal damping for single-axis solar tracking systems, providing stability during rotation and wind resistance. 🌟 Horizontal single-axis trackers 🌟 Tilted single-axis trackers 🌟 Vertical single-axis trackers 🌟 Ground-mounted power stations, especially single-axis or dual-axis solar tracking systems.

Dual-Axis Trackers

Dual-Axis Trackers

Advanced damping solutions for dual-axis tracking systems requiring precise control in both azimuth and elevation. 🌟 Tip-tilt dual-axis trackers 🌟 Azimuth-elevation trackers 🌟 Polar mount trackers 🌟 Rooftop PV systems (primarily fixed mounts, but some use hydraulic dampers for precise angle stabilization and movement control).

Large-Scale Solar Farms & Special Scenarios

Large-Scale Solar Farms & Special Scenarios

Robust damping solutions for utility-scale solar installations with high reliability and performance requirements, and for specialized applications. 🌟 Utility-scale ground-mount systems 🌟 Desert and harsh environment installations 🌟 Coastal and high-wind areas 🌟 Elevated parking lots, agricultural-photovoltaic complementary projects, etc., where tracking brackets are integrated with heavy-duty solar dampers to mitigate wind-induced tensional vibration, prevent aeroelastic fluttering, and safeguard the automated drive system.

Installation & Maintenance

Correct installation is the single biggest factor in damper service life.

View Detailed Installation & Maintenance Manual
  1. 1Mount with the dust cover facing upward (Big End Up) to keep dust, sand, and water out of the seal.
  2. 2Keep the rod clear of the stow and rotation path to avoid side-loading and bending.
  3. 3Apply the specified torque on end fittings and verify mount alignment before commissioning.
  4. 4Perform a visual seal and mounting inspection during routine O&M — no lubrication is required.
