Cool your home in the summer

Solar Attic Fans Cool Your Home in the Summer

The Professional Series Solar Powered Attic Fan 9920TR effectively reduces attic heat build-up in the summer months and moisture in the winter months. With 43% of air conditioning base on high attic temperatures frequently up to 160F, lowering attic heat typically lowers air conditioning run-time.


Installing a Solar Powered Attic Fan will help remove the heat build-up in your attic and bring your attic’s temperature down closer to the ambient outside temperature.


The reduction in attic temperature will also benefit the homeowner by preserving and extending the life of the roofing and attic construction materials. Additionally, hot air in your attic can then heat the metal exterior of your HVAC ductwork and consequently heat the air passing through it, causing your air conditioner to work even harder.



Solar Attic Fan Prevents Mold and Milder in the WinterRemove damaging moisture

In the winter months, the building materials in your attic can absorb up to 28 gallons of moisture, contributing to mold and mildew growth. Moisture migrates into the attic space from daily activities such as running the dishwasher, showers and cooking. Additionally, warm attic air meeting the cold roofing materials creates condensation, which drips onto the attic insulation causing it to lose its effectiveness. Warm attics in winter also contribute to ice damming as the snow melts on the roof and re-freezes at the eaves, causing water to accumulate.


Installing a Solar Powered Attic Fan will allow for better air flow and moisture control inside your attic and prevent the condensation which can lead to mold and mildew problems.

Product Features
Lower your energy costs
Attic temperatures can exceed 160° F in the summer months heating up air-condition ductiing and radiating heat into your home. This forces your air conditioning to work harder.
Adjustable Solar Panel
It is important to capture as much of the available sunlight as possible. Orient the solar panel by tilting and/or swiveling the panel assembly to the position that will face the sun at it's highest point during the day.
Ventilates up to 2400 square feet
One attic fan will ventilate up to 2400 square feet of attic space depending on the slope of the roof and available sunlight. Add more fans for larger attics.
Removes Damaging Moisture
In the winter, moisture is constantly added to your home by the washing machine, showers, and dishwasher. During the winter, this moisture can migrate to the attic and condense in the cool air promoting the growth of mold and mildew.
Cools Your House In The Summer
By expelling the hot attic air and pulling in cooler air from the soffit vents, your house will stay cooler.
Oversized Flashing
US Sunlight's oversized flashing is made of a heavy gauge steel and has been designed for leak-proof installation. The attractive black powder coating blends in with any roof color.

What are the cost benefits of installing a solar attic fan?


How much money you will save is greatly dependent on the price of electricity in your area, the amount of attic space in your home, the efficiency of your attic insulation, the amount of tax credit and rebates available in your area and the amount of ventilation your solar attic vent is able to provide.  In our experience, a typical installation will usually pay for itself within 1-3 summers of use verses  powered Attic Fans that can cost up to $35 per month to operate.



Does my roof already have ventilation?


Static vents or ridge vents will help but generally do not provide sufficient air movement to pull heat and moisture from the attic – especially during the winter or when the ambient air is stagnate. If you have electric fans in the attic, you will benefit from increased air movement in the summer but at a cost of 350 to 400 watts of power per day!


Often, electric attic fans have a thermostat that keeps them inoperable during the winter, just when you need them to expel moisture! A solar powered attic fan runs whenever there is sunlight – and, at no cost of operation.



Is a solar powered attic fan difficult to install


The Solar Powered Attic Fan is extremely easy to install. A homeowner can install one in less than an hour and a professional in less than 30 minutes. An installation video is available on our website and you can receive additional help by calling 866-446-0966. Only basic tools are required and there is no electrical wiring to connect.


We would be glad to refer you to an installer in your area if one is available. If there is not one available we would suggest you call a local handyman or roofing contractor. Your retailer does not provide the installation and does not make any arrangements with any installers, so it is best to call US Sunlight at 866-446-0966 to find out what options for installation services you might have available in your area.



Are tax credits available for installing a solar powered attic fan?


Absolutely.  The fan qualifies for up to a 30% Federal tax credit.  There may be additional energy rebates or tax credits available through your local utility. You can obtain an IRS form 5695 through the internet or visit our Tax Credit Info page on our website, download the form and learn about other possible rebates that may apply.



My current electric fan is noisy and can be heard from inside the home. Is the solar attic fan noisy?


The solar powered attic fan is extremely quiet.  The solar cell provides power to a super-quiet DC motor.  There is no harmonic hum that is common with AC motors.



What is the life expectancy of the solar panel?


The Solar Powered Attic Fan has the latest state-of-the-art solar panel designed to last for more than 20 years.  While a standard solar panel can last 5 years or less, our solar panel has a 20 year prorated warranty – the longest warranty in the industry!



Are there difference in the solar powered attic fans available in the market?


Yes!  It is possible to find several brands and models with different prices and features.  But our Solar Powered Attic Fan has some of the best technology available at the best price, to assure that you have a fan that will last for years to come.


  • Our Solar Powered Attic Fan includes a commercial grade, hail resistant solar panel with a unique tilt-swivel design. By maximizing the solar panel’s orientation to the sun you can gain up to 25% more power.
  • We offer a 20 year limited warranty on the solar panel and a 5 year warranty on the motor.
  • Our motor warranty is one of the longest in the industry. In addition, our top of line motor has been designed with a simple brush replacement feature, assuring many years of worry-free performance.



Is a building permit required to install the Solar Powered Attic Fan?


To our knowledge, no permit is required.



Is additional wiring required?


Additional wiring is only required when installing the included Solar Controller. The fan itself will run independently without additional wiring, but in order to enable post-sunset ventilation, wiring of the Solar Controller is required.



Can the black housing be painted to match the roof shingles?


Yes it can, but you should first prime the housing with an acrylic paint. Be sure to not apply any paint to the solar panel surface.



Can I replace my existing static or turbine vent with the solar powered attic fan?


Yes, in most cases the solar powered attic fan will directly replace existing vents making the installation even easier. In some cases, you may need to modify the existing opening, the installation documentation will take you through each step.



Will the solar powered attic fan continue to run after dark?


Yes. With the addition of the Solar Controller, The Solar Powered Attic Fan can be simultaneously connected to your house electricity and will run for 8 minutes every half hour after dark to provide additional ventilation after sunset.



Can the solar powered attic fan be used to vent garages?


Yes it can! Many of our customers are using the fan to reduce the temperate in the garage or storage shed.



Will the solar attic fan leak?


The Solar Powered Attic Fan is designed to not leak and includes an oversized, steel zinc coated roof flashing integrated into the design.  Please refer to the easy installation instructions included in each unit as well as the online video.
