Natural Light- 12 Watt Solar Attic Fan

The 12-watt 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 it is powerful, operating at up to 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.

Lowers attic temperature which can reduce the load on the HVAC (air conditioning) System. 
The most obvious reason for attic ventilation is to lower attic space temperature during the warmer months. Attic temperatures can exceed 160°F during hot summer days. Proper attic ventilation can reduce those temperatures by 50°F.  Proper ventilation evacuates this excess heat build-up. As the heat is exhausted the work of the air conditioning system is reduced thereby saving energy and extending the life of the air conditioning system.
Extends the life of the roofing materials.
Though asphalt shingles are designed to take the abuse of the sun for many years, they are subjected to greater temperatures when the roof decking is allowed to overheat, which is just what happens in an under ventilated attic.  

In the cooler months, moisture is the most serious concern.  Even with the use of vapor barriers to keep moisture from entering the attic, there are air leaks around ceiling light fixtures, bathroom exhaust fans that allow unwanted moisture into the attic.  Moisture condensing on the framing members and the inside of the roof deck can lead to the growth of mold, mildew and rot in the roof deck and framing.  A good indicator of moisture problem is rusty roof nails sticking through the roof deck.
Asphalt shingle manufacturers warranties require proper attic ventilation.
Attic ventilation is required in cold environments-it evacuates the warm moist air that heat sources produce. Hot moist air lingering in the attic spaces can condense on the underside of the roof sheathing and rot it out and also causes mold to develop on the interior walls.

Good ventilation helps prevent ice dams, which begin to form when warm air in the attic melts the snow from beneath and creates runoff that refreezes on the colder eaves. An optional shut-off thermostat is available for colder climates.
Critical Factors that impact solar powered attic fans unique to our product:

Minimized backpressure of exhaust gases: Natural Light Solar Attic Fan incorporates an angled throat within the flashing that provides a venturi effect, which increases airflow.

The design from the ground up is to minimize obstructions in the flashing and shroud to also increase airflow.

The unique Natural Light designed mounting bracket allows for optimum angling of the solar panel for maximum exposure to the sun.

The mounting bracket allows for remote mounting of the solar panel that allows for optimal panel / flashing placement.

Design minimizes the ambient temperature of the solar panel keeping the solar panel cooler for maximum power output.

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.

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

Constructed of powder-coated heavey-duty .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.

Thanks to use of industry leading manufacturers of solar panels, low voltage DC motors and the use of high quality materials and precise construction techniques employed, this product is covered by an industry leading 25 Year Warranty on housing, solar panel and motor!
