I think that's just what it is in Greece: you buy a package with a
collector and plumbing all connected up and stick it on your (flat) roof.
Cheap as chips over there and AFAIK not a gov't subsidy in sight.

We need something that frost proof so it has to be indirect and use a
frost protected working fluid.
