Gable mounted fans, meanwhile, will cost an average of $245, according to Fixr. These fans are energy efficient and installation is a breeze, as these fans can be installed in existing vents. Roof mounted fans, which, of course, are installed on the roof, cost an average of $275.
Generally, solar attic fans will cost between $200-$500, according to HomeAdvisor. Anyone purchasing a solar attic fan may qualify for a federal tax credit. These fans will essentially cost nothing to operate and they will never create any negative pressure zones or pull hazardous gases from home appliances. AngiesList says home and business owners will save on energy costs for years to come after installation.
Solar Attic Fan Pros
Here’s a look at some of the benefits of solar attic fan installation:
Runs On Solar Energy
It costs less to run a solar powered attic fan because it is powered by the sun. Meaning, you won’t need any electricity from your home or business to power it up. This save on electricity costs and is also great for the environment. It also wastes less energy and is a more attractive option that other motor powered attic fans.
Makes Attic Space Cooler
Another great PRO about solar attics fans is that they cool down your attic space. Cooling down your attic is the best way to keep your home cool too. The more hot air you keep out of the attic – The more hot air you keep out of your home. This will also keep the attic free from dust and dirt. Solar attic fans will keep your home’s ambient temperature low to reduce cooling costs.
Less Expensive Than Full Ventilation Systems
Solar attic fans are also generally less expensive and easier to install than full ventilation systems. They require less time and a less invasive installation process than these other systems do.
How Do Solar Attic Fans Work?
Solar attic fans work by efficiently reeling in the cold air from the soffits. Then, the fan will push out any hot air that has found its way to the top of the attic, resting just below the fan’s position. Essentially, this is exactly hot air moves naturally. Cold air remains at the bottom, while warm air stays on top. Attic fans will help move the air, adding cooler air circulation within your home or building.
Attic fans will provide a constant and steady air flow throughout your attic and home. Stale warm air is vented out of the attic, giving the area more fresh cool air. This transfer is commonly known as an “air exchange.” While it may seem normal for your attic to be one of the warmest areas of your home, the experts say this room should never be 10-25 degrees above the outside air temperature. A properly ventilated attic can drastically reduce your total energy costs.
In the winter (usually not a problem in a place like Arizona), warm moist air will rise from the inside of the home, eventually colliding with the cool air near the roof. Solar attic fans will provide circulation to prevent air from condensing on the surface, which keeps your attic dry.
