To remedy this situation, you need to get more air cooling fans or air conditioners. One key area people fail to consider when it comes to cooling their houses is an attic fan.

This goes a long way in ensuring your house does not retain heat in the roof, which cancels the effect of your air conditioning. A great option would be to get a solar-powered attic fan. This will help to reduce your energy bill by tapping into the sun instead of your electricity.

Are Solar Attic Fans Worth It?

Yes. Attics get hot and humid during the summer months. This can lead to the accumulation of moisture that can lead to the growth of mold and mildew. Additionally, a cooler attic will reduce the strain on the central air conditioning system as it will not counteract the HVAC system’s cooling effect.

A solar attic fan will also reduce your cooling energy bill. The reduced strain on the HVAC will mean a reduced need for cooling the house. Not to mention the solar-powered attic fan is also energy efficient.

Where Should A Solar Attic Fan Be Installed?

The best place to install your fan is on the side of your roof that has the most direct access to sunlight as this will ensure it absorbs enough sunlight for powering the fan. It should also be on a slanted part as this will prevent water from pooling around the panel and seeping into your roof. Lastly, ensure that the fan is mounted at the section of your roof that gets relatively warm during the summer. You may need to use a thermostat to figure this out.


The best solar attic fan should be compatible with a large variety of roof types. It should also be able to store energy for powering the fan when there is no sunlight. Look for an attic fan that has a thermostat for temperature control as well as a weatherproof solar panel. If in doubt, pick one of the options reviewed above.
