Carl, Rob Haddock, the founder of S-5! Attachment Solutions just wrote a Q&A response for "SolarPro" magazine. In it he writes:
"Aluminum S-5! clamps are compatible with all these metals except copper. When roofing is copper, brass S-5! clamps should be used. Somewhere between the brass clamp and the aluminum PV frame an electrolytic switch must be made. This can be done with a passive metal like stainless steel or with rubber isolators or both." You can read the entire article online in HTML format, or download it as a PDF for free. You just need to subscribe to either the digital or print version of the magazine. The subscription is free and it takes less than 5 minutes to set up an account: solarprofessional.com/subscribe I'll defer to others for their favorite S-5! Supplier, but this should not be difficult to find.
