Adding a solar attic fan to an upstairs room in your home could be a permanent solution to overheating during the extreme Arizona summers. If you are wondering if solar attic fans work, the answer is a resounding yes!
How Do Solar Attic Fans Work?
The first question any potential customer has is how exactly the solar fan works to circulate the attic air. These fans will work by pulling in cold air from the soffits, then pushing any hot air outwards. Essentially, this motion mimics exactly how air naturally circulates. Warm air will always stay up top, with cold air always resting below. Attic fans aid air circulation and movement in your home or building’s attic, where overheating is common.
Solar fans are placed in the attic to provide a constant and efficient air flow throughout the day. Stale, warm air is vented outwards to keep the area cool. The solar professionals refer to this process as the “air exchange.” While most people assume the attic should be the warmest area of the home, experts suggest this room should never be more than 10-25 degrees above the temperature outdoors. A properly ventilated attic area will undoubtedly save home and business owners on energy costs for years to come.
During the colder seasons, warm air rises inside the home. This air eventually collides with cooler air, occurring near the roof. Solar fans prevent air from condensing on the surface, which keeps the attic area dry.
Why Install A Solar Attic Fan?
Here are just a few advantages associated with installing a solar attic fan in your home or business:
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.
Solar Attic Fan Installation Cost
Solar attic fan installation will cost $675, on average. Prices will range from $575-$775 for this project.
Best Solar Attic Fans
Here are three types of solar attic fans currently available through Elite Solar Systems in Phoenix, Arizona:
10-Watt Solar Attic Fan
A 10-watt solar attic fan may not be as powerful as other models, but it is certainly worth the investment as a homeowner. This model features 800 CFM (cubic feet per minute) and can efficiently remove heat and moisture from the air. The 10-watt will protect your home’s roof by reducing any premature aging of shingles. A solar attic fan will reduce attic temperatures, which will preserve the life of the room and your roof. Without a solar attic fan, your home’s air conditioning system will have to work even harder. This will cause your bills to increase wildly, especially in the Arizona summers.
20-Watt Elite Master Solar Attic Fan
The 20-watt version, available through Elite Solar Systems, comes with an adjustable solar panel up to 1,400 CFM / 2,000 square feet. These fans are designed for homes of less than 2,000 square feet. In that size home, you can count on the fan to exchange air every 11 minutes or approximately 5.5 times per hour. These attic fans also work great for any garage ventilation needs!
30-Watt Elite Master Solar Attic Fan
This large solar attic fan features an adjustable solar panel up to 1,700 CFM / 2,500 sq. ft. It is the recommended size fan for a home of 2,500 sq. ft. or less. The larger fan means it is capable of working harder, especially during the hotter months. These fans can exchange air every 14 minutes or about 4.5 per hour.
