Soda Can Solar Heater

I made a solar can solar heater. Fairly simple, collect a bunch of cans, drill/cut out the top/bottom, assemble into tubes, assemble tubes into a panel, paint panel, stick in window.

Cans in tubes:


Can tubes made into a panel:


Painted and installed:


The bad thing is that I figured out that in the winter the sun doesn't go directly overhead, it is inclined. We are on the wrong side of the building, so the windows do not get direct sunlight.

In the summer, on the other hand, we do get direct sunlight as it is inclined the other way. Sooooo.. that sucks.

I might donate the panel to my sister or mom.
