Isn't it kind of obvious, that a "photovoltaic" type power generator is
located on top of the building rather than inside or below?
You may assume a basic level of intelligence from the user of the data
and add only information that has more than one option. E.g. is the post
box attached to a wall or does it stand on its own? In this example you
would not need a relation, since the post box node can simply be joined
with the building way.
If there is something notable about the object, you could also start
with a note=* tag that describes the interesting features. If there are
more advanced tagging schemes in the future, other mappers can apply it
without visiting the place again.
