A friend of mine from my gun forum built this. I'm not so sure I like it. Would not it be more efficient to operate if the cans were replaced with tubes filled with anti-freeze? They might take longer to warm up but would hold the heat longer. I also think he needed to make his panel more weatherproof with better seals/insulation around the edges.
He also is planning to use manual valves to seal it off but I think it would be far better if he used louvers that were pressure sensitive, when the solar panel is not running the fan, the louvers would be closed. I have suggested those changes, which he is considering.
For your consideration:
50inx81in 235 cans.
This is a work in progress.2 inch intake and exhaust.The reason for the size is the cover is going to be half of an old sliding glass door.
The plan is to place this on the south side of the house and run 2 inch pipe from the floor level(intake)and run 2in pipe close to the ceiling for the exhaust.
