Buying a Solar Attic Fan

Installing a home attic fan is essential if you want your home to be more energy-efficient.

The size

To calculate the size of each room separately, multiply the width, length, and height measurements you recorded earlier. Add the size of each room to match the size of the entire house. This number will eventually affect the amount of power you need in the fan.


First, you will carefully measure the length and width of one room at a time, as well as the height from floor to ceiling. While this includes smaller spaces such as bathrooms and hallways, it does not include cabinets or other areas where the door remains closed. When measuring a conventional or solar extractor, the proper measurements are vital.

Ventilation area

To determine the ventilation area in your attic, divide your CFM rating previously by 750. So if you are at 3000 CFM, your ventilation area will be 4. It is essential to realize that this number is the area network of ventilation and not the actual dimension of the unit. Thus, it not only represents the home attic fan but also for checking faults and nozzles.

Cubic feet per minute

To determine your CFM rating, you will divide the total size by three. This new number is one cubic foot per minute for your entire home. So if your overall size is 9,000 cubic feet, the fan you buy will need a rating of at least 3,000 CFM.

Gable Mounted Fans vs. Roof Mounted Fans

The openings through which this air passes may or may not be covered with the net, but when purchasing equipment for a fan used to ventilate the attic, it is highly recommended to use a profit covered hood as it prevents the entry of animals and waste.

On the other hand, roof-mounted fans include high and low ventilation options. With top openings, this indicates a section of the ventilation system that allows hot air to be carried out in the attic. For this, you will have a choice of hills or gable grooves. Regarding low openings, this part of the system design is really mandatory to return cold air from outside to the attic.

The cost of installing an attic fan installation is between $300 and $600. At most, you will use nearly $550, including labor. Apart from that, there are factors that affect the final cost. Some of them include the time of the year, energy, professionalism, and the availability of technology.

What is the Average Life Span of a Solar Powered Attic Fan?

The warranty gives the whole lifespan of a solar attic fan. If you read online reviews well, you will note that most attic fans come with a 25-year limited warranty which covers that whole unit.

Attic Fan vs. Full House Fan

A solar attic fan ought not to be confused with a whole house fan, which has an alternate use case. While an attic fan removes tourists from the attic through the rooftop, a whole house fan removes sight-seeing from the house through the attic and takes into account cooler air to come in through the windows.
