Hi Super;
I read a great article on a home built solar wall (the home power link in the article). You might want to have a look before you carry on. It turns out black window screen can be a very good solar collector in this application.

Instead of aluminum cans for heat collection you may consider just painting the foil on the insulation a flat black. The trouble with these types of solar panels is the active process for farming the heat away from the panels and into the house. Too many people stuck them up on housetops and ran faulty plumbing through their roof-lines, causing some serious mayhem. But for warming sheds and non-living spaces its a good idea.
We experimented with some windows about a decade ago and found them to be good for keeping the pool warm during the summer. But we found just lining the baby pool with rubber - and covering it with clear plastic in the winter like a cold box - actually collected far more heat until the snow fell. (The baby pool was 18" deep and approximately 6' by 12'. Nice sized rectangular sections of rubber manufactured for roofing can be found fairly inexpensive, if not free in the dumpster from the right job sites. And the rubber held up well for a decade, even with the kids using it on a fairly constant basis.
I think I've seen all of your videos at one time or another over the past six months. Keep up the good work.

Nice project Windy,
You can share any subject on the forum (within reason), it doesn't have to be wind power necessarily.
As MattM suggests,painting the foil on the insulation a flat (matt) black might be a simpler solution
I am not quite sure why the cans are being used.

I'd have though that the cans were used as they give a larger surface area (corrugated front),hold more heat than the foil and channel the airflow better, but IMHO the fan would be better blowing denser (cooler) air in at the bottom than sucking thinner (warmer) air out. Hef  |

A piece of corrugated sheet metal siding is pretty inexpensive and would produce uniform results across the panel. Several magnitudes cheaper than the several cases of barley soda it takes to do one panel. :)
