Dana--We did a 12" sip w 5/8 osb on a 3:12 roof using DPWs Easy Feet. We needed a PE review and stamp for the permit.Easy Feet were set 44" apart. The system was in profile and the IronRidge xrs rails were set 41" apart for the 300W 72 cell modules w Solar Edge optimizers in Allentown, PA. Design snow load was 30psf. The Easy Feet worked great, but you have to set them right the first time. Mastic will not let go to fine tune. Bill Hennessy Berks Solar, LLC 371 Centennial Rd Mertztown, PA 19539

I had aluminum "plates", 8"x8" and 1/8" thick made up by a local fabricator. We also fabricated flashing for the topside using 12" aluminum. We used threaded bolts running through the SIP (9 5/8") to another 8"x8" metal plate on the underside. Unfortunately, this will not be a finished look. The underside of the roof we installed on was the underside of the SIP (sheathing). 8 years later, this roof remains leak free and full of modules......There are obviously more details to the install, but I don;t think this method will work for you.....
