( www.s-5.com ) aluminum clamps that squeeze down on the vertical part of the roofing (the "standing seam"). Onto those clamps you mount the aluminum rails and then the PV panels onto the rails. This will work with any type of framed panels. Its nice because it is quick, you don't have to drill holes through your brand new metal roofing and the clamps can be positioned wherever is convenient.
