Any homeowner who wants a comfortable attic should seriously consider investing in one of the best solar powered attic fans. As their name suggests, these fans are powered by solar energy, and this means they will have zero impact on your electric bill.
They work with the existing vents to improve the circulation of air in your attic. According to research, temperatures in the attic can exceed 100 degrees Fahrenheit during summer. These fans have been proven to lower temperatures by up to 40 degrees Fahrenheit.
Most attics are well insulated, but this does not prevent heat from being transferred to adjacent rooms. Well, top-quality solar-powered attic fans exhaust the excess heat build-up, thereby, reducing AC run times and HVAC loads. This, in turn, helps cut electric costs. Nevertheless, before you choose an attic fan, you must know the capacity of your attic and which types of fans can best serve it.
You also must know how sturdy an attic fan is to avoid buying a new solar-powered fan after just a few months. Another thing you must have in mind is the warranty. Get all of these factors right and you will be a proud homeowner. In our reviews, we have talked about the models you should have on your list during the hunt for a new solar-powered attic ventilator.
