Solar Attic Fan Installation

Make Your Home More Comfortable & Energy Efficient

In Central Florida, attic temperatures routinely hit over 150°F, forcing your air conditioner to work overtime and dramatically increasing your monthly bills. When you deal with that kind of intense heat, the only solution is precision-engineered ventilation. Solatube’s Solar Star® Attic Fan is not an off-the-shelf accessory. It is a robust, premium system designed specifically to withstand and defeat our climate’s relentless heat and humidity.

These ventilation fans harness solar energy to ventilate your attic space, effectively reducing temperatures that can soar up to 150°F. By actively removing hot air and drawing in cooler outside air, solar attic fans help maintain a lower, more consistent attic temperature. This temperature regulation helps to protect your home by reducing the strain on your air conditioning system, resulting in significant energy savings and lower utility bills, and extending the lifespan of your roofing materials by decreasing the likelihood of heat-related damage. 

In addition to temperature control, solar attic fans play a crucial role in moisture management. During cooler months, warm air from your living spaces can rise and condense on the chilled surfaces in your attic, leading to moisture buildup. This excess moisture can cause structural damage, promote mold and mildew growth, and compromise indoor air quality. Solar attic fans prevent these risks by enhancing air circulation and expelling moist air, thus protecting your home’s structural integrity and creating a healthier living environment.

Another compelling benefit of solar attic fans is their eco-friendly operation. Powered entirely by solar energy, these fans require no electricity from your home, making them a sustainable choice that reduces your carbon footprint. The solar panels capture sunlight and convert it into energy to run the fans, providing consistent performance without any ongoing operational costs. Additionally, solar attic fans are designed to be maintenance-free and operate silently, ensuring a hassle-free and quiet solution to attic ventilation. With professional installation by The Solar Guys, you can enjoy the peace of mind that comes with improved home efficiency, enhanced comfort, and a greener lifestyle.

Frequently Asked Questions

Solar Attic Fans

Is the Solar Star Attic Fan quiet?

The Solar Star® Attic Fan features a brushless DC motor that reduces noise and lightweight, polymeric fan blades that minimize vibration. The result is whisper-quiet operation.

How does the Solar Star Attic Fan perform in extreme temperatures?

The Solar Star® Attic Fan is designed to work in the harshest of climates, from the scorching southwestern regions of Arizona and Texas to the frigid northern areas of Canada and Alaska. Featuring a Venturi design for maximum airflow capacity and durable polymeric fan blades for high performance and reliability, the Solar Star Attic Fan equalizes interior and exterior temperatures to safeguard your home against the extremes of summer and winter.

Do Solar Star Attic Fans run at night?

There are no batteries on Solar Star® Attic Fans that will store energy. Thus, they only run when daylight is available on the solar panel.

Does the Solar Star Attic Fan have an on/off switch or thermostat?

Attics are meant to be ventilated year-round, and the Solar Star® Attic Fan is designed to run whenever daylight strikes the solar panel. During the winter, proper ventilation helps prevent condensation from forming within the attic. If moisture does accumulate, it could cause significant heat loss from the home if the attic insulation gets wet. A cool, dry attic is the best solution for keeping heat inside during the winter. If your attic is properly insulated and moisture buildup is not a concern, but cold temperatures are, then the optional Solar Star Thermal Switch may be the solution for you.

While the Solar Star Attic Fan does not have an on/off switch, the optional Solar Star Thermal Switch can be added to turn off the fan when the temperature in the attic is cooler than 65° F (18° C). It will also turn on the fan when the temperature in the attic is warmer than 85° F (29° C), giving you greater control over the operation of your Solar Star Attic Fan.

What if I install a Solar Star Attic Fan on a section of the roof that doesn't have all-day sun exposure?

The Solar Star® Attic Fan runs best when the solar panel is in direct sunlight. Although the unit will continue to operate in the shade (provided the sky is bright), it will run at a reduced speed. On a roof that is heavily shaded for most of the day, a Solar Star Roof Mount 1200 Add-on Panel is recommended. The extra panel can be placed up to 15 ft (4.5 m) away from the main roof unit—if possible, in an area that has all-day sun exposure—to boost performance.
