Residential Solar Attic Fans

In case you have an extra bedroom upstairs that tends to get too hot during the summer, your solution is to have a solar attic fan installed in the attic. It will help in cooling your room, hence making it more comfortable during the hot weather. All that you need to do is purchase the number of fans needed, depending on the size of the space. Some spaces might require you to use three or more fans.

The best part about using solar attic fans is you will have free energy supply throughout its lifespan. Once the fan has been installed, you will have no bills to worry about, and your room temperatures will always be conducive.

How Solar Attic Fans Work

Just as the name suggests, solar attic fans use solar energy to operate. The fans pull the superheated air from the attic and replace it with cooler air from outside the house. As a result, the work done by your HVAC to cool the upstairs rooms will be highly reduced.

If you live in the northern hemisphere, you need to ensure that the fan is on a south-facing roof slope. Such would allow it to acquire as much solar energy as possible, thus making it more efficient. If the fan does not absorb enough solar energy, its effectiveness might be reduced.

You need your fan to operate at high speed always to avoid high temperatures in the room. Such can be best achieved by ensuring that the solar gets enough energy.

Benefits of Solar Attics


The solar attic fans do not draw a lot of air compared to the line-powered fans. Therefore, they do not risk filling the house with carbon-monoxide gases, which might cause death. The line-powered fans can create areas of negative pressure, which would, in turn, pull conditioned air into the attic area. Such creates the risk of pulling carbon monoxide back into the house from combustion appliances. Therefore, solar attic fans are safer.
