Pros and Cons of Solar Attic Fans Pros and Cons of Solar Attic Fans
Solar attic fans are overhead ceiling fans that are designed to help circulate air in the attic. They are powered by solar energy, making them a unique fixture in many homes and a progressive, environmentally conscious addition to a home space. While there are many benefits to including a solar attic fan in your home, there are also some disadvantages and reasons why other systems of air circulation may be more effective. Read on for a brief overview of the pros and cons of a solar attic fan in your house.
Pros of Solar Attic Fans
One of the primary benefits of a solar attic fan over other types of fans is the fact that it runs on solar energy. This means that it will not require electrical power from your home to operate it, which helps to save on electricity costs. It also is beneficial for the environment and is typically less wasteful than other types of fans. All of these are important energy considerations for a solar attic fan, and help to make it a more attractive option than many other types of circulating systems.
Another benefit of a solar attic fan is that it can help to make the attic space more comfortable. By adding a fan to your attic, you help to move the air around in a place that otherwise may not have very good ventilation. This can not only ease your comfort level while you work in the attic, but it may also help to keep the attic cleaner and free of dirt and dust. Removing hot air which would otherwise be trapped in the attic can also help lower the ambient temperature in the home, which can also reduce cooling costs.
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.
Cons of Solar Attic Fans
There are also a number of negative points to keep in mind when you're considering installing a solar attic fan in your home. First, the air in the attic is generally warmer than in the rest of the house, owing to the fact that hot air rises. This means that your solar attic fan may only help to blow around hot, humid air in the attic. This can reduce the effectiveness of the fan as a tool for creating ventilation and air circulation.
Solar powered appliances and fixtures are also somewhat risky because of the fact that they rely on the sun in order to operate. If the weather outside is poor, it may be difficult to operate your solar attic fan, or you may have to conserve your usage of the fan.
Finally, solar powered attic fans tend to not be as powerful as other types of attic ventilation systems. Electric fans and other types of fans are oftentimes able to operate at a higher speed, thereby enhancing the benefits. And full ventilation systems tend to be much more effective at climate control than fans are in general.
