Having a hot attic is no fun, especially if you for some reason want to be in that attic.

From the site:

The Solar Attic Fan is a simple and environmentally sensible solution that can save you money. Powered completely by free solar energy, this sleek and efficient vent is both compact and quiet. Fully operational right from the box, it installs easily, with no electrical wiring, no expensive electrician and city permits. And let’s not forget powerful! Operating at a whopping 850 cfm, a single unit can fully vent up to 1200 square feet. Place it wherever you need improved circulation; attics, lofts, workshops, storage sheds, garages, even barns.

At over $350 you might want to just use natural venting, but if you really need the ventilation this is a good easy option that will not make you run wires. And the Natural Light comes with all these handy features.

1. Minimize backpressure of exhaust gases.
   • Natural Light incorporates an angled throat within the flashing that provides a venturi effect, which increases airflow.
   • Natural Light was designed from the ground up to minimize obstructions in the flashing and
     shroud.
2. Maximize the exposure of the sun to the solar panel.
   • Natural Light designed a mounting bracket that houses the solar panel that allows for angling the panel.
   • The mounting bracket allows for remote mounting of the solar panel that allows for optimal panel flashing replacement.

3. Minimize the ambient temperature of the solar panel because power output rapidly declines as temperature increases.

   • Natural Light

     powder coats the entire assembly in a neutral gray color thus ensuring that it does not act like a heat sink.

   • The solar panel mounting bracket allows for an envelope of cool air to continually circulate around the entire solar panel.

4. Adaptable to any location, roof type, in any environment.

   • Natural Light is constructed of .080 (14gauge) aluminum, the flashing and shroud are seamless ensuring weather tight installations.

   • Stainless steel animal protection screen.

   • Stainless steel hardware throughout.
   • Powder coated to withstand any environment.
   • Fifty year Neutral Cure silicone bonds the flashing to the roof.
