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.

the flat bar is between the angle on the roof and the angle on the panel to raise it up a bit so it separates them by a 1" or so.
Now I understand. It's a 3-part Z-bracket.
You can make it simpler and more reliable, a 2-part:
2" angle on the roof, and another 2" angle upside down on the panel. Both angles are joined with machine screws and lock-nuts along the vertical surface. Or, better yet - a pair of 3" angle pieces, then you'll have more surface area on the vertical adjoining sides.
Online Metal Store - a source of aluminum angle of any size. They can cut it into short pieces for a small fee. Or cut it yourself, a hack saw will do.
You should really have a wider foot on the roof than 1" angle that you are considering. The wider the angle - the better seal with Dicor.
Yea it is kind of like a 3 piece z I wanted it that way in case I ever wanted to change the height. The angle is what I found at Home Depot it's 1 1/2".
