New roof in the works gave me a chance to see how it's constructed. Would a roof-mounted solar system be safe?
It's a vaulted ceiling, no attic. The layers from inside out, visible in the pics I took last night"
* 4" x 10" beams every 4' (edges are thinner 2x10)
* 2x8 tongue-in-groove, probably fir
* foam sheet
* 1x6 every 12" laying flat, nailed to the T-in-G sandwiching the foam.
* Plywood decking stapled to the 1x6.
* Tar paper
* Composite shingles
Before the roofing job started I had one Tesla inspector come out and he said absolutely not and cancelled the job. But he also said the T-in-G was obviously foam, which it definitely isn't, and he said he was doing me a favor because, at the time, our roofing job wouldn't start until July so Tesla would cancel it regardless. So I called the project advisor and she said that didn't sound right and reinitiated the job for me.
I have a quote from another installer who seemed unconcerned.
But, man, that solar would just be bolted to decking. Couldn't attach to rafters if you wanted to, they don't exist.
We definitely get high winds and rain. Would a roof-mounted system be safe up there? Should I go with a ground system?
