I replied about this on another comment but have a look at "We Do Solar" their product is designed for installing on balconies but I guess there is nothing to stop you installing it where ever you like! (You might just need to add a bit of a frame to support them?)

Beware, those tend to be ballasted, for mounting on a light roofing structure you really want something that isn't ballasted.
