Solar Attic Fans.
Solar attic fans circulate hot air out of your attic and are powered by free energy from the sun. If you have an attic fan already then you should consider replacing it with a solar attic fan. Doing so will save you money on your utility bill. If you do not have an attic fan then you may be able to save a significant amount of money on your utility bill when you install a solar attic fan. There is a 26% federal tax credit available for installing this type of fan. The average payback period is 1 to 2 years.
