Why Solar Attic Fans

Here we have some reasons why you should use solar-powered attic fans. What advantages will you get with a solar attic fan instead of a grid-powered model? Of course, many of you have the same doubt, especially when the solar attic fans are quite expensive than their traditional grid alternatives.

1. Cut on Your Power Bill

The primary reason is that you could get a cut on your power bills. You need to run attic fans constantly to ensure fresh air inside your attic spaces. It is not always expensive to rely on electricity to do so.

It is here a solar attic fan will come in the help of you. They will run your fans all the time around with solar energy. Though most of the best solar attic fans are battery-free plug-and-play solutions, some models are there with built-in rechargeable power back-up options.

So, you could utilize solar power to keep your attic spaces fresh round the clock. During the day, it would be running on the solar energy directly, and in the nighttime by the stored power in the battery.

2. Easy-to-Install and Operate

It is another lovely thing with solar attic fans. All the best solar attic fans are DIY solutions. You could yourself fix them and start removing the heated air to cool your attic space. The function of an attic fan is also very simple. It works instantly after the sunlight hits the included solar panel.

3. Perfect for Small Rooms, RVs, and Campers

Solar attic fans are not heavy machines. They are small devices with low-power profiles to remove bad air from your small living spaces. In that sense, they are surely ideal picks for your small rooms, cabins, RVs, campers, trailers, and more. We have listed out some of the best attic fans suitable for such small living spaces above.

4. Environmentally Friendly Solutions

Of course, running on solar power, attic fans are eco-friendly. Everybody wants free energy and looks for environmentally power solutions. So, you could better try an attic fan at least in your small rooms, RVs, campers, and more. For larger rooms, solar attic fans may not be a good choice, though.

Why Not Solar Attic Fans

Absolutely, some experts claim that solar attic fans are not powerful enough to remove the sufficient bad air to lower the attic temperature of a big room. An average solar attic fan could only pull out less than 1,000 cubic feet a minute, which would contribute nothing to the decrease of temperature.

Anyway, we would like to recommend you try out an attic fan in your small living spaces only. It would surely work finely in small enclosures like RVs, cabins, campers, and small bedrooms as well. If you have another experience, share them in the comments below.
