Solar Powered Exhaust Fans

Roof Fan 20 watt ©Copyright
Summary: The Benefit of Solar Powered Exhaust Fans is that attic venting is an important aspect in maintaining a healthy energy efficient home. Proper venting cools your roof extending the material life and reduces the load on your air conditioning system.


Advantages of Solar Powered Exhaust Fans


Excess moisture trapped in your attic can cause a variety of problems from rust and rot to increased bacteria and mold counts which can have a direct impact on your respiratory health!


Passive vents have been a part of building codes for years. Soffit vents, ridge vents and louvers rely on nature to provide sufficient air pressure and air movement.


So the majority of the time your attic is stagnant and continues to build up heat and moisture. Solar powered exhaust fans can help prevent these problems from occurring in your home.



Solar Attic Fans

Solar Powered Exhaust Fans are the Natural Choice in Attic Venting!
Solar powered exhaust fans are 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! A single 10 watt unit can fully vent up to 1,200 square feet, operating at up to 850 cfms. Place it wherever you need improved circulation; attics, lofts, workshops, storage sheds, garages, even barns.




Benefits of Solar Powered Exhaust Fans


Attic venting is an important aspect in maintaining a healthy energy efficient home. Proper venting cools your roof extending the material life and reduces the load on your air conditioning system. Attic venting also increases fresh air circulation which reduces vapor build up generated by every day activities like showering and cooking.

1. Minimize back pressure of exhaust gases.
• Quality Solar Exhaust Fans incorporates an angled throat within the flashing that provides a venturi effect, which increases airflow.
• High Quality Solar Exhaust Fans are designed from the ground up to minimize obstructions in the flashing and shroud.

2. Maximize the exposure of the sun to the solar panel.
• Quality Solar Exhaust Fans will designed a mounting bracket that houses the solar panel that allows for angling the panel.

• Some solar exhaust fans offer an optional special order remote solar panel which is installed away from the attic fan housing. It is used in applications where there is limited sunshine where the unit is to be installed. The remote panel is installed in a sunny area, capturing maximum amount of sunlight and therefore achieving optimal attic fan performance.

3. Minimize the ambient temperature of the solar panel because power output rapidly declines as temperature increases.
• A well made solar exhaust fan powder coats the entire assembly, inside and out, 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.
• Quality Solar Exhaust Fans are constructed of .080 (14 gauge) 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.

Benefits of Solar Powered Exhaust Fans

Lowers attic temperature which reduces the load on the HVAC 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 up to 50°F. No matter how much insulation is in the attic, heat can still transfer into adjacent living spaces. In fact, extra insulation can actually add to temperature increases because heat is trapped in the insulation. Proper ventilation evacuates this excess heat build-up. As the heat is exhausted, the work load 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.

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. Cold air in the attic space will not affect the temperature in the adjacent living spaces if properly insulated.

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.

Solar Powered Exhaust Fans - The Environment

Solar Fan Parts

Better by Design...High Quality Solar Attic Fans are engineered to be the best, incorporating the best features, the best materials and the best construction, making it the Natural Choice over our competition!

Adjustable Solar Panel
Our solar attic fan is designed with a mounting bracket that houses the solar panel allowing the panel to be angled for optimum performance. Many of our competitors offer a fixed solar panel which can hinder the units performance.

Powder Coated Inside and Outside
Quality Solar Exhaust Fan materials have powder coats over the entire assembly in a neutral gray color thus ensuring that it does not act like a heat sink. Many of our competitors either paint only the outside or do not paint the unit at all.

Aluminum Fan with 5 Blades
Quality Solar Exhaust Fans offers a five-wing precision balanced aluminum blade for the highest cfm output. Many of our competition offer only 3 or 4 blades and many are made of plastic.

Aircraft Grade Aluminum Flashing
A quality solar attic fan flashing are manufactured from aircraft grade .080 gauge aluminum while many of our competitors flashing are manufactured from sheet metal or galvanized steel.

Aircraft Grade Aluminum Hood
High grade solar attic fan hoods are also manufactured from air-craft grade .080 gauge aluminum while many of our competitors offer either polypropylene (plastic), sheet metal or galvanized steel.

Best Product Warranty in the Industry
A Quality Solar Exhaust Manufacturer will offer a 25 year warranty on the housing, 15 year warranty on the solar panel and a 5 year warranty on the motor - the best warranty in the industry.
