Will these work with Unistrut or superstrut rails from Home Depot?

Yes 1/4" hardware or you can drill out for larger holes

What is the distance between the 2 holes? Is there a U-bolt size that will fit the 2 holes to mount the panel on a car roof rack?

From center to center, 3 and 5/32 inches. 1/4 inch diameter holes. I don't know about the U-bolts, but some U-bolts I have would fit, they are from antenna riggings.
