Terry had actually discovered a plan for a solar heat collector composed of empty aluminum cans. Using this method, Terry was able to change the temperature in his house up to 7 degrees and it costs only $1.50 a year to run. That’s right, only $1.50.

So, how exactly can empty soda cans help with the temperature in your house? The simple answer is that they suck in the cool air from the house, heat up the air inside, and send the warm air back out into the house using a fan and vent system.

Plus, the cans were painted matte black to help absorb the sun’s rays even more efficiently. This helps makes the empty soda cans as warm as possible, which helps keep your house nice and warm!

As you might have guessed, this DIY solar panel works best when it has as much access to the sun as possible. If you live in a generally overcast or rainy area, or the solar panel is located in a somewhat shady spot, you may not have much luck with it.
