  • 5 to 30 Degree Tilt
    With tilt options ranging from 5 to 30 degrees, Precision RMS is suitable for rooftops in northern latitudes.
  • Prepanelization
    Modules are prepanelized (potentially off-roof or off-site) into assemblies of 2, 3 or 4 to speed up module installation by 50 percent.
  • Roof-Friendly
    Features rubber feet which absorb thermal expansion within the system and prevent any metal from touching the roof — often eliminating the need for slip sheets.
  • Stands Up to the Harshest Environments
    Able to withstand conditions in the highest wind, snow and seismic zones.


The highly engineered Precision RMS makes solar a viable option for a much wider range of commercial rooftops.

How does Precision RMS make solar possible for a more diverse range of roofs?

With two load optimizing substructure options — one that includes feet that can be adjusted to align loads with structural elements of the roof and a second that distributes loads along the length of the long beam — Precision RMS is ideal for roofs with limited deck capacity.  Uneven surfaces can be also be accommodated with excellent roof following capability.

Is Precision RMS a solution for roofs in challenging environments?

The system’s stiffness and linked rail design can withstand conditions in the highest wind, snow and seismic zones and its aluminum and stainless steel components can endure even the most corrosive environments.

How are Precision RMS components delivered to site?

Precision RMS fast-tracks installation and improves total system quality by delivering components preassembled to the project site.

What is prepanelization and how will it help me?

As the Precision RMS substructure is being installed, modules can be simultaneously prepanelized(potentially off-roof or off-site) into assemblies of 2, 3 or 4 to speed up module installation by 50 percent.

How is grounding accomplished?

When it comes time to ground the system, Precision RMS’ integrated grounding feature saves even more time and money.

Is Precision RMS roof friendly?

For building owners, Precision RMS offers all of the roof friendly and O&M features for which SunLink is best known. System feet are made from recycled rubber tires, which won’t damage the roof surface and may even eliminate the need for slip sheets.

Does Precision RMS have any features that simplify roof maintenance?

The system features Tilt Access™ to facilitate roof maintenance and an open design for unimpeded roof drainage and airflow.
