You can dip your toes in the solar energy waters by simply installing a solar powered whole house fan. A solar powered attic fan turns on automatically when it becomes too warm. You'll reduce the cost of cooling your home by having this solar-powered attic fan remove hot air from your home. Additionally, as it is solar powered, your power bill will go down, not up.
