Do a search on Trickledown solar, or Modified Trickledown.<br>
Very cost effective. I'm planning on doing one, after some
other must-do items get handled first. There are a number of
examples out there, starting with Thomason's design in the 60's, I
believe still providing heat for a Vermont building.<br>

A few links:<br>

Does anyone have experience with, an opinion or knowledge of transparent exposed water collectors?
That is, a flat plate solar water heater where, instead of running the water under a copper field absorber,
the water runs between a glass face, and an absorbing surface. In such a device, the sun's heat would not
have to flow through a copper sheet to be drawn-off with water, but would be taken from the very surface
that absorbs it. A further development could be a dense black mesh in the cooling water, throughly scrubbed
of it's heat. A glass plate exposed to 60+psi would not be pretty, but under low (drain-back) pressure...
