Jay, We're basically at the mercy of racking and module manufacturers to get their documentation all lined up for us and very few have actually done so. To answer your question, I believe the answer is that we do need to buy listed racking and module combinations. My understanding is that most standard PV modules are type 1 but I have yet to verify that. SunPower is type 2. The racking instructions then need to specify what type(s) of racking system, modules, and roof classifications are compatible (roofing class A, B, or C).
We have a good deal of stock of racking in our warehouse and I'm crossing my fingers that we can use it come next year. We also use customized tilt racking for low slope (flat) roofs and I'm still unclear on how we're going to deal with that.

And I don't know where to find a list of listed components/systems. Anybody know? thanks in advance, jay peltz power _______________________________________________ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.htm l List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org _______________________________________________ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out or update participant bios: www.members.re-wrenches.org
