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.

PS:
in the retrospect, there could be a reason why my super-buper ultrasound stud-finder could barely see the rafter under 3/4 particle board: rafter was too far below. There was often a gap 1/4"-3/4" between the particle board and rafter. Don't try squeezing this gap down to zero, stop when Dicor starts coming out from under the bracket. In my trailer the ply was not screwed to the rafter in the middle of the roof, except for where there were 2 adjacent sheets of ply.
