Cory I tried a railless S-5 system on a metal roof and will never do it again! Looks great and very professional. The clearance under the modules is a real problem for wire management and I had to switch out a bad microinverter and it was really difficult compared to have a rails. Had to disconnect all adjoining modules from the S-5 which allowed things to shift a bit making replacement an absolute pain in the butt. It was a steep roof too which added to the hassle....bad choice for my first try ,but it was a triagular array shape due to shading issue sand dormer locations. That was why I opted for railess, since the cutting of rails would have been very time consuming.
