attaching solar panels to a metal roof

The electrical side of installing a solar electric system is a pretty straight forward process although when it comes to the mechanical aspect of attaching solar panels there can be a lot of variances based on the type of roof. One of our customers was involved with a new home construction project that had a standing seam metal roof. He called us and asked us to design and provide him with a complete solar electric system that would attach to the metal roof. The 4.1 kilowatt grid tie solar electric system consisted of 18 Canadian Solar CS6P 230 watt solar panels with an Enphase M190 Micro-inverter behind each solar panel converting the DC power generated by the solar panels into grid compliant AC power. Attaching the solar panels to the metal roof was easy by combining the UniRac SolarMount Rails with S-5-U Clamps made by S-5!. S-5! clamps attach to the seam of a metal roofing by the tightening of two “bullet-nosed” stainless steel setscrews against the seam material. The round point setscrews compress the seam material against the opposite wall of the clamp. The clamps will “dimple” the seam material, but will not penetrate it. Threaded holes in the clamp enable the easy attachment of the UniRac SolarMount Rails to the clamps. The customer was able to attach the solar panels to the metal roof by taking advantage of the S-5! clamps. The picture above shows the installed solar panels, what do you think of the outcome of his...
