If you're going to run it on the roof,I recommend that you soften the front and side perimeter with convex radii equal to the panel thickness,and a gentle ramp off the rear face to keep flow attached back down to the roof surface.This ramp could taper in at say 5-degrees at the sides on each side for a tiny improvement.
The sides will help in crosswinds.
