Product Overview
The S-5! SolarFoot is a mounting platform for attaching the L-foot of a rail-mounted solar system to an exposed-fastened metal roof, such as AG-Panel or R-Panel. The L-foot is not included.
SolarFoot sits in the flat of the panel between the ribs and fastens through the roof into the supporting structure. S-5! says it must go into wood decking, wood or steel purlins, or trusses, never into the metal roofing alone.
Factory-applied butyl sealant in a reservoir seals the base. An integrated stainless M8-1.25 stud and an M8 hex flange nut hold the L-foot.
Best For
- Exposed-fastened metal roofs such as AG-Panel or R-Panel: S-5! says SolarFoot fits almost any trapezoidal-rib, exposed-fastened profile.
- Rail systems that use an L-foot: S-5! describes SolarFoot as a pedestal for the L-foot of a rail-mounted system and says it is compatible with rail manufacturers' L-foot components.
- IronRidge XR Flush Mount: IronRidge's XR Flush Mount Installation Manual (Version 5.2) lists SolarFoot among the third-party roof attachments tested or evaluated with the XR Flush Mount system. IronRidge says to follow S-5!'s instructions for installation.

What You May Also Need
Usually required
- An L-foot from your rail system: Sold separately. Check that its base fits over the M8 stud. See roof mounts.
- Fasteners for your roof structure: S-5! says the fasteners in its instructions must be used when relying on tested load values.
- Rails and rail hardware: See metal roof mounts.
May be required
- Tools: S-5! lists an electric screw gun, rag, string line, tape measure, a 3/8" hex socket and a 13 mm (or 1/2") hex socket.
Optional upgrades
- A string line: Helps keep a row of SolarFeet aligned.
Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.
Important Considerations
- Into structure only. S-5! says SolarFoot must never be fastened into the metal roofing alone.
- Attachment spacing. S-5! says attachment frequency and spacing for PV arrays are the system designer's responsibility.
- Engineering is your responsibility. S-5! says the user or installer is responsible for all engineering and design, including spacing. S-5! publishes load test results on its website for load-critical designs.
