  • The Natural Light Energy SAF20B 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! A single 20 watt unit can fully vent up to 2,000 square feet, operating at up to 1,275 cfms. Place it wherever you need improved circulation; attics, lofts, workshops, storage sheds, garages, even barns.

    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.

    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.

    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.

    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.

    I have finally received the fan after ordering the product a month ago. It took me 3 phone calls to Smarthome to attempt to check on the status of the order. I never received any return information until the product shipped out, which was the day I was going to cancel the order and order from someone else.

    Its upside down. The thermo sensor wire needs to hang from six o clock position but this means the panel will raise towards the vertical. Optimum angle for me at 35 latitude would be 12 below horizontal. Can't be achieved.
