Sundeavor stocks S-5!'s S-5-U and S-5-Umini clamps, as they are an extremely popular and versatile clamp that works with most standing seam metal roofs. (Is not compatible with copper roofing material)
S-5! puts it best:
"The concept of combining photovoltaic arrays with standing seam metal roofing is growing—and for good reasons. A standing seam metal roof has a life expectancy consistent with that of framed PV modules."
A 30-year power source on a 40-year roof, along with zero-penetration technology, creates the most sustainable roof system available with alternative power generation, all without compromising the roof manufacturer's warranty!
