A solar fan, sometimes known as a solar attic fan, is an overhead fan that circulates attic air. Because these fans are entirely powered by the sun, they are an excellent investment for both residential and business properties. These fans provide year-round circulation, which is especially advantageous in a hotter area like Arizona.
What Is The Function Of A Solar Attic Fan?
What precisely does a solar fan accomplish to circulate the air in your attic? These fans work by sucking cold air from the soffits into the room. The fans will then force any hot air beneath the fan outwards. This motion is essentially the same as how hot air travels naturally. Warm air rises to the top, while cold air sinks to the bottom. Attic fans are designed to help with air movement and circulation in your house or business.
Solar fans will offer a steady and efficient air flow throughout the attic on a daily basis. Warm, stale air will be evacuated outwards to provide more cool air to the region. This is referred to as the “air exchange” by experts. Although it may appear that your attic is the warmest part of your house, experts advise that this space should never be more than 10 degrees warmer than the outside temperature. Your energy bills will surely be reduced if your attic is properly ventilated.
During the colder seasons, warm air will rise from the inside of the house. Cooler air near the ceiling will eventually collide with this air. Solar fans keep the attic area dry by preventing air from simply condensing on the surface. In a place like Arizona, this is usually not an issue.
The Different Types Of Solar Fans
These are the three most common varieties of solar fans, which can be found in both commercial and residential settings:
- Solar Attic Fan, 10-Watt
- Solar Attic Fan (20 Watts)
- Solar Attic Fan, 30 Watts
Read on to learn more about the benefits of each model.
Solar Attic Fan, 10-Watt
Although a 10-watt solar attic fan is not as strong as other types, it is well worth the money for a household. This model has an airflow rate of 800 CFM (cubic feet per minute), which allows it to effectively remove heat and moisture from the air. The 10-watt will protect your home’s roof by preventing shingles from prematurely deteriorating. A solar attic fan will lower attic temperatures, extending the life of your room and roof. Your home’s air conditioning system will have to work more harder if you don’t have a solar attic fan. This will cause your bills to skyrocket, especially during the hot summer months in Arizona. According to Homeadvisor, the average price is between $200 and $500.
Solar Attic Fan, 20-Watt Elite Master
Elite Solar Systems offers a 20-watt version with a solar panel that can be adjusted to 1,400 CFM / 2,000 square feet. These fans are intended for households with a square footage of less than 2,000 square feet. The fan will exchange air every 11 minutes, or around 5.5 times per hour, in that size home. These attic fans are also excellent for garage ventilation! Price range: $200-$500+
Solar Attic Fan, 30-Watt Elite Master
This huge solar attic fan has a solar panel that can be adjusted to provide up to 1,700 CFM / 2,500 sq. ft. of airflow. For a home of 2,500 square feet or smaller, this is the suggested fan size. Because the fan is larger, it can work harder, especially during the hotter months. Air is exchanged every 14 minutes, or around 4.5 times per hour, by these fans. Installing solar attic fans today will help you save money on heating and cooling. Price range: $200-$500+
Pros of Solar Attic Fans
- Powered by solar energy
- Cools down the attic.
- Full ventilation systems are more expensive.
- Powered by Solar Energy
These fans are far less expensive than most conventional fans since they are driven by the sun. This means that these fans will not require any additional electricity from your house or company to operate. Solar attic fans are becoming increasingly popular for a variety of reasons, including cost savings and environmental benefits.
Attic Area Is Cooled
Another advantage of solar attic fans is that they will significantly cool down your attic space. Cooling the attic will also help to keep the rest of the house cool. The more hot air kept out of the attic, the less hot air is kept out of the house as a whole. Solar attic fans are also known for keeping dangerous dust and debris out of the attic space. Maintaining a low temperature in your home will help you save money on future cooling expenditures.
Full Ventilation Systems Are More Expensive
Solar attic fans are less expensive and easier to install than complete ventilation systems. The installation of these solar attic fans takes substantially less time and is far less invasive.
Cons of Solar Attic Fans
- Attic fans with motors are more expensive.
- Attic fans that aren’t powered by motors aren’t as powerful.
- To function properly, the sun is required.
- Attic Fans With Motors Are More Expensive
Solar attic fans are more expensive since they are newer and use more technology to blast hot air out of the attic area. They’re also more expensive to set up than a standard motor-driven fan. However, over time, the energy savings from these models will greatly surpass the expensive installation expenses.
Attic Fans That Aren’t As Strong As Motorized Attic Fans
Because they consume electricity, motorized fans are more powerful than solar fans. Using electricity, on the other hand, will be more expensive to run than relying on the sun. As a result, even if motorized fans blow out more air, the added expenditures make this an unwise investment.
To function properly, the sun is required
The only risky aspect of buying and maintaining a solar attic fan is this. Your fan will not work properly if you reside in an area with limited sunshine. Other locations, like as Phoenix, Arizona, give the ideal amount of sunlight for these fans.
How much does it cost to install a solar attic fan?
The average cost of installing a solar attic fan is $675, with prices ranging from $575 to $775. Installation of wall-mounted solar attic fans will cost around $650. The cost of the fans ranges from $550 to 770 dollars. Installation of gable-mounted fans, on the other hand, costs an average of $245.
Are Solar Attic Fans Worth It?
Yes, solar attic fans are worth. According to SolarEnergy, solar attic fans remove hot air from your attic which allows your A/C to put out cooler air, makes your roof last longer, and makes your home more comfortable. According to HGTV, “Solar powered fans can make a real difference if you regularly use the space adjacent to your attic. “
