Looking for a cost efficient alternative to solar panels?
Check out the whole house fan:

Q: What is a whole house fan?

A: Whole house fans are an alternative type of home cooling unit. They come in two main construction models: belt-driven, and direct-driven. Direct-driven fans are cheaper, but tend to be noisier than belt-driven fans.

Q: How does it work?

A: Simply open up a few windows and switch the fan on! The fan draws in cool air from outside and moves it through your home to create a breeze. Hot air in the home gets pushed up into the attic where it is ventilated. An additional attic fan can be paired with the whole house fan to push hot air out of the attic more effectively.

Q: Why should I add a whole house fan?

A: A whole house fan can be paired with your air conditioner to reduce your monthly cooling cost. It doesn’t replace A/C on those sweltering summer days. It will, however, work very efficiently to get cool air from the outside into your house.

Q: How much does it cost?

A: All you need to start cooling your home is the whole house fan component. Extra ventilation is optional. The cost with installation but without extra attic fan ventilation runs about $1,200 – $1,550.
