S-5! designed the SolarFoot support to mount PV arrays on exposed fastener metal roofing such as AG-Panel or R-Panel. It is an ideal, weatherproof mounting platform for the L-foot of rail mounted solar systems. The SolarFoot provides excellent support for the L-Foot of most commercially available PV racking manufacturers.
The bottom surface of the SolarFoot comes with butyl co-polymeric sealant, creating a permanent water seal once it is pressed on the roof surface. The butyl sealant comes in a walled reservoir, preventing over compression of the sealant. The stainless integrated stud and hex flange lock-nut secure the L-Foot into position. All perforations are distributed with a low center of gravity that reduces the moment arm commonly associated with L-Foot attachments.
The SolarFoot is placed in the flat of the roof metal panel, between the ribs. It must be mounted directly over and into the supporting structure of the roof, for example wood decking, wood or steel purlins, or trusses; never install into the metal roofing material alone.
Roof fasteners are not included with the SolarFoot. The selection will depend on the supporting structure under the roof:
– For wood sub-structures use 1/4-14 Type 17 AB Milled Point screws, size 1-1/2” to 2-1/2”.
– For metal structures use 1/4-14 Self Drilling screws size 1-1/2” to 2-1/2”
