attaching solar panels
I was wondering if I should use well nuts or just wood screws to attach the panels to the roof, of course a healthy amount of Dicor. I was going to use 1" stainless wood screws.

6 brackets per one 255W panel should be enough. If you are making your own brackets, cut them 5-6" long so the load will be distributed.
OEM mounting holes in the bottom of the frames are for permanent mounting on the shore homes, and assume some racking underneath, like rectangular tubing etc. If you use Z-brackets on those holes without racking, it will be difficult to remove the panel later unless brackets are either very tall or are 2-part.
made my own brackets from 1" aluminum angle about 3 1/2" and using a 1" flat bar between them to raise them up a bit and make for easy removal if needed.
