Solar Cool 800 CFM 10-Watt Solar Powered Exhaust Roof Mount Attic Ventilator

A smart alternative to conventional roof vents, the Solar Powered Attic Vent operates during the day and collects power from the sun to convert into electricity. In turn, this energy operates a high efficiency motor inside the power vent, so there's no added cost for electricity. That saves energy, which is better for the environment.
