Rotate solar dampers 4–5 times after installation!

 Rotate solar dampers 4–5 times after installation!
Because this simple step makes a big difference.
Although solar dampers are built to withstand wind, shock, and years of outdoor exposure, they don’t reach full working condition the moment they’re mounted. They need a brief activation process — and here’s why it matters:

The core reason:

To stabilize internal damping performance and ensure the damper works as designed.
Let’s break that down:
Redistributing Internal Oil
Dampers use silicone or hydraulic fluid to create resistance. During storage or transport, this oil may settle. Rotating the damper a few times ensures the oil is evenly distributed across the entire working chamber — especially around the piston and seals.
Engaging the Seals
Many dampers contain precision sealing systems to prevent leakage. These seals often require a few cycles of movement to fully seat and create the proper internal pressure balance.
Removing Trapped Air
Air pockets inside the damper (from filling or transport) can compromise damping force. Rotating helps purge these bubbles so the damper delivers smooth, reliable resistance.
Stabilizing Resistance (Torque)
The first few turns help the damper reach its intended torque curve. Without this step, you might see irregular or inconsistent performance — especially when the tracker first faces wind loads.
Verifying Proper Installation
During rotation, any unusual noise, stiffness, or leakage can be detected early. This gives installers a chance to fix issues before the system goes online.
 

So next time you install a solar tracker damper, don’t forget to rotate it 4–5 full cycles.
It’s quick, simple — and absolutely essential for long-term system performance.
