Hanger bolts came in for for my solar panels. I really messed up, they are much smaller than I needed. They are about the same size as the ones they had at the hardware store, so kinda negated the whole idea of ordering online. i wanted the lag bolt part to be 3 inch but instead the whole thing is 3 inch. Was a derp on my part when I ordered. These might still be strong enough though, it's not like the panels will see as much wind being on the wall as the wall will shield them, and if they get hit directly or at an angle it's going to push on them, and not lift. There will be some pull force but not as much as when they are on the roof.
Going to attempt the roof again though, since I can't return those mounts that I paid like $260 for. Maybe if I use a heat gun and exacto knife I can manage to get the shingles to separate.
My schedule sucks though, I hardly have any time off. I hope I get put on more 12h shifts next schedule.
