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.

No respectable installer will put 35-45 lbs panel onto EPDM roof attached with adhesive only. There are occasional dimwits though.
Small 100-160W panel that is neither lifted few inches (to clear protruding vents, A/C shade etc), nor tilted, should be fine on 4 brackets, 2 #10 screws per bracket.
It is recommended to have at least 0.5" clearance between the panel frame and roof, for heat dissipation.
Keep in mind that so called flat panel should still have few degrees slope to drain water, snow and debris. This slope occurs naturally when conforming to the roof slope, and is not the same as "tilted" panel.
