I would have to cut down so many trees around my house to get effective sunlight on the roof more than a few hours a day. Plus my roof is pitched east/west so at best I have half the roof in sunlight for half the day. I do have quite a bit of clear space behind the house, so I could consider a system that sits on the ground. I just like paying the utility every month and not having to worry about owning, maintaining, and repairing my own infrastructure though. As it is now, if anything goes wrong upstream of the meter, that's not my responsibility.
