A window in a house is already a very good solar collector. For our purposes, there's little difference between window glazing and solar collector glazing. It's already collecting about as much sun energy as a collector panel in the same location would collect and it's already delivering that energy right to the house - no need for fans or ducts or pumps or piping.

The window glazing works the same as the glazing on a solar panel, just as the stuff inside of your house works just like the absorbers in a panel. Adding an absorber surface on the inside of a window may even cause more heat loss since the higher temperatures near the window will increase the losses through the glass.

Take care, Scott MD

Good info, Scott!

Or you can do what I did. I made a collector that "drops down" from our small bathroom window. It only blocks the bottom 1/4 of the window and drops down 7 feed to collect lots of free hot air from Mr Sun
Mine has a case fan that runs off a little PV panel to move the air. I have thought of adding another fan on the other side to move more air thru the panel. In full sun it's 68-70 degrees F going in and about 115 coming back.

Hey, Mitch !

That looks like a very nice  idea !

Would you  have an outside view, by any chance ?

Hi Mitch,

What kind of air collector are you using?  Great use of a small window and still get light in.
