Panel size didn't line up with the beams and I didn't use the 4' beams initially.
The roof is peaked and the beams are flat on 4' centers. Removing some ceiling items like lights determined one location. I drilled a small hole next to one from inside to determine it's exact center location from the roof. From the roof for other beams I drilled a small hole and used a small wire to confirm. I used 3" screws to secure the al angle.
Good to know. I'm hoping my install goes a bit easier. This is making me consider those glue-down no-drill mounts... But I don't know that I'd ever be comfortable driving down the road with glue-on mounts...
