System Components

To build a fully functional system, the following components are required.

Rails

GFT Rails

Supports modules These beams run perpendicular to the top chord channels and directly support the solar panels, which are attached using clamps.

Piles

C-Piles

Main structural member of system the anchors the array to the ground. These are the primary vertical supports for the array. Made of steel, they are available in 10.5’, 12.5’ and 15’ lengths so they can be driven directly into the ground for a stable foundation.

Rails

Top Chord

Attached C Pile to GFT Rails which support the module. These are horizontal structural beams that run along the top of the C-piles. The east-west rails are attached to them to support the solar panels.

Rails

Splice

Connects 2 segments of GFT Rails.

Clamps

Mid Clamp – Universal AF

Offers ½” row spacing. 30mm – 46mm modules.

Perfect balance between aesthetics/module gaps & engineering benefits

Hexagonal hardware is designed to help align clamps with module frames for easier installation

Clamps

Mid Clamp – Standard Series

Offers ¼” row spacing.

The smallest module gap for great aesthetics and module density on the roof.

Low-cost, simple design.

SKUs are available for different module thicknesses between 30-51mm.

Clamps

End Clamp – Universal AF
