Essential Info

Does your attic overheat during the summer? Have you ever worried about, or found, mold and/or mildew in your attic during the winter? If your answer is yes, then US Sunlight Solar's 9910TR 1,150sq/ft Ventilating Solar Attic Fan is a must have. During the summer your attic can rise to temperatures upwards of 160°! A result of this is that your air conditioner will over compensate in an effort to cool the entire house down which in turn leaves you with a huge and unnecessary electricity bill. Now you may be asking yourself, "how can a fan help my attic during the winter?" The answer is that warm air from your home rises up into the attic throughout the day and eventually interacts with your cool and damp roof. This creates moisture in the air and can lead to the formation of mold and mildew without you even knowing.

Having a Solar Attic Fan from US Sunlight Solar will help regulate your attic temperature by using the free and clean energy provided by the sun. During the warm months the fan will draw out the warm air sitting in your attic while at the same time pull in cooler air from outside. This leaves your attic and house at a more stable temperature leading to less wasted electricity by your air conditioning unit and thus, smaller electricity bills. Now, during the winter months the fan will remove the moist air that is created by the mixture of the warm rising air from your rooms below the attic and the cool underside of your roof. This leaves you with drier air in the attic and thus prevents the growth of harmful mildew and mold which need dark, wet spaces to thrive. This mold and mildew build up can lead to much larger problems down the road as well as causing your family to be more prone to sickness.

The 9910TR Solar Attic Fan is powerful enough to ventilate up to 1,150 square feet. Because this attic fan is solar powered it will run year round at no additional operating costs to the user and even begin to pay for itself with the savings you'll see on your monthly energy bill. This solar fan is also capable of being tied into your houses power connection with a Solar Controller to allow the fan to be operated at night when there is no sunlight. The fan has a powerful 38 volt motor but is whisper quiet while operating so that you, the user, won't even realize it's there. It features 3 high efficiency fan blades that sit in a 25 gauge steel housing which will not dent or rust to provide years upon years of optimal service. The solar panel is commercial grade and encased in a hail and high speed wind resistant covering that can be tilted and swiveled so that it receives the best sunlight possible. The solar panel itself is a 10 watt panel and even comes with a 20 year manufacturers warranty to ensure the quality of the product. If you're ready to begin taking advantage of the free energy provided by the sun and start seeing monthly savings on your electricity bill then this is the product for you.

The Federal tax credit for solar attic fans has been extended through 2016. The Solar Powered Attic Fan is eligible for a 30% (up to $1,500) credit on the purchase price of the fan, installation and sales tax. Check with your tax consultant and county for these potential added benefits.

    The fan also comes equipped with a thermal switch which allows the attic fan to automatically run when temperatures exceed 80°. However, this switch can easily be bypassed should the user prefer that that fan run continuously throughout the day. This is done by disconnecting the black leads from the thermal switch and re-connecting them directly to the motor. Refer to the installation manual or product video (below) for further instructions on how this is achieved.
