Solar Guppy
Red Cobra Guppy
I used the site before to try to figure this out. I called electric co-op and AHJ and was just bounced around with no answers. This is why I started focusing on ground mount
And maybe why the roof installer who also does solar did not even want to discuss it along with roof warranty.
The ones permitting make the rules, find out from them what they expect for wind loads, snow shouldn't matter as that isn't a racking issue, if it would pass on the ground, it would pass on a roof.
Once you have the wind design requirement, then you can use the design tool to come up with a racking plan.
The only difference on racking is the spacing on the feet and the series for the rails, for me and 145 mph, it was every 4ft to rafters and using the 100 series rails. It is a GREAT system and worth every penny. Don't ever use L brackets, you will end up with leaks eventually, look at how the Iron Ridge mounts seal the penetration, it will never leak.
As for your roof warranty, that will be void for anything you do, as long as you install as directed, the Solar mounting will not increase the chance of leaks and will actually protect the shingles below.
You should understand that in general, installers like cookie cutter designs and have no financial incentive to do out of the box designs, if you want Solar, you will have to do the legwork to come up with a permittable design, it isn't hard, but will require effort. Don't overlook the electrical side and the need for UL9540 listed system, that will likely be a much bigger challenge than racking / where the panels end-up.
