Has anyone built a south-facing roof on a building that's 45 degrees off?

I have the opportunity to add an attached garage to my house, and I'd like to provide a plaftform for solar PV on the roof (Zone 5, NW Ohio). The existing structure (and the entire town) is oriented 45 degrees off; that is to say, the street runs northeast/southwest. I'd be attaching the garage on the side of the house that faces southeast.
