Dual rail attachment reinforces rails and splices
Maintains roof integrity for lifetime leak-free function
H.F.S.M. features a hole-less design that avoids puncturing the external shingle layer by anchoring underneath the shingle course, at the traditional nail strip below. The unique solar mount preserves a roof's integrity, synergizing with its normal function to provide a leak-free installation for life.
H.F.S.M. earned numerous awards from the United States Department of Energy, was granted a patent in 2026, and is now in national demand by homeowners, contractors, and even insurance agents who desire longer-lasting roof-top attachments.
H.F.S.M. is compatible with practically all railed and rail-less PV module mounting mechanisms which accept horizontal attachment, including Martin's very own newly released Dual-Channel Solar Rail.
