Comparing Electric And Solar Attic Fans

Attic fans are one of the most important parts of your roof, as they work to vent heat out from beneath your roof and help keep humidity and heat levels low in your attic. This makes it much less likely for mold and mildew to begin to eat away at your roof, which can cause costly repairs. Two of the most common types of attic fans are electric- and solar-powered attic fans, both of which accomplish the same function but do so in different manners. Understanding the differences between these two types of fans can help you choose the one that is the best fit for your roof.

Electric Attic Fans

Electric attic fans are plugged into your electrical system and are highly efficient at removing air from your attic. Depending on the power of a particular model, electric attic fans are able to cool down your entire house, which can help reduce your energy bills by reducing the load placed on your air conditioner. Finally, electric attic fans tend to be easier to install than their solar counterparts, as they do not require the installation of solar panels and additional accessories beyond basic electrical wiring.

However, electric attic fans still represent an energy expenditure, which increases their long-run costs when compared to solar attic fans. Additionally, electric attic fans will cease to function in the event of a power outage, which can leave your attic and home stuck in the heat during the summer months.

Solar Attic Fans

Solar attic fans, like their name suggests, make use of solar energy to vent air out of your attic. Because they are not plugged into your electrical grid, they won't raise your energy bills at all during operation, which means that they will give you more energy savings when used to cool down your home when compared to their electric counterparts. Besides the financial benefits that this represents, solar attic fans can also reduce your home's environmental impact. Furthermore, solar attic fans will continue to work in the event of a power outage as long as it is sunny outside.

However, the main downside of solar attic fans is that they will not operate during cloudy weather, which can make them a poor choice depending on your climate. Furthermore, solar attic fans tend to be less effective at venting air out of your attic when compared to electric fans.
