A quality solar attic fan can manage to drop the temperature up to 10 degrees Fahrenheit. Thus, providing you with optimum room temperature without even bothering you. Moreover, a solar attic fan is a one-time low investment that lasts for decades without demanding any replacements.

The only catch here is- not every attic fan is built similarly. Some of them might fail to meet your expectations. However, don’t worry at all. We’ve got your back.

After performing a tonne of research on the solar attic fans available in the market we’ve made a list of the best. This list will help you to pick the most ideal option without wasting much time.

To decide the ideal solar attic fan, you should have at least a rough idea about the comparing factors. Looking at the factors mentioned below will give you a better idea about what to look for.  

Coverage Area

Every attic fan provides you with a specific coverage range. In such a case, you should make sure that the attic fan you’re considering should easily control the temperature of your place. The coverage area of the fan is primarily dependent on the motor wattage it comes with.

A fan with a high wattage motor will cover more area as compared to the low wattage. However, a high wattage motor demands more energy too. Your solar power might fail to provide much power on cloudy days or you might’ve to pay much on electric bills if plugged in with a power supply. 

You should look at the motor wattage, the area covered, and the fan speed of the solar attic fan to have better insight.

Wall-Mounted Vs Roof-Mounted

Every solar attic fan is either one of these types- Wall-Mounted Vs Roof-Mounted. It is totally up to you who’ll be more appropriate for your needs.

The Wall-mounted attic fans are easy to install and don’t have to bear those rough weather environments directly. Moreover, these fans cost less than the roof-mounted attic fans.

Roof-mounted fans require a vent in the attic. They’re more energy-efficient as the solar panel is installed along with them. 

You might need a detailed insight on other important factors of the fan as well. This is why we’ve included a “Buying Guide” at the bottom of this article for convenience.

But, now, it’s time to begin the best solar attic fan hunt.

Buying Guide of Best Solar Attic Fan

This is time to move one step ahead. The list mentioned above includes some of the top-notch solar attic fans. To compare the products previously you’ll need to have a better insight. The buying guide mentioned below will help you to make the final decision.

Roof Mounted Vs Gable Mounted

Different attics, garages, and greenhouses require different methods to prevent the overheating issue. The same goes while installing the solar attic fan as well. These solar attic fans are available in two different types- Roof and Gable Mounted.

This gives you the flexibility of installing a solar attic fan according to your location and needs. Let us know which would be more appropriate for you.

As the name suggests, the roof-mounted fan demands a vent in the roof for the installation process. After installing properly, the remaining vent is mostly covered by the shingle to maintain the beauty of the roof.

These fans don’t require large cable as the solar panel is mostly installed with them. Thus, getting the utmost sunlight and increased inefficiency.

Gable-mounted on the other side is connected through a solar panel and can be installed in a desirable wall/gable. They’re easy to install and cost low as compared to the roof-mounted attic fans.

Area Coverage

Considering the area coverage of your solar attic fan is the foremost thing to consider. The bottom line here is obvious- it should be more than the area of your attic/garage. Ensuring the bottom line will maintain the optimum temperature even during heatwave summers.

The solar attic fans come with different powered motors. Thus, they’ve distinct area coverage too. You should have a look at the wattage of the motor, the fan speed (CFM), and the area coverage of the solar fan for precise capacity.

Keep in mind, the higher these numbers will go, the pricier will be the fan. Also, a high watt motor demands more energy consumption. 

Thermostat and Humidistat

The thermostat and humidistat aren’t the mandatory features here. But, they will have some importance in maintaining the optimum temperature and moisture for your desired area.

The thermostat helps the fan to know better about the temperature of its environment. In this way, the fan automatically starts blowing whenever the temperature rises. This also prevents the fan from useless running during winters or monsoon seasons.

In general, the thermostat is preset with many solar attic fans but many manufacturers include it separately.

Maintaining a perfect humidity level is like a constant analytical process. Both low and high moisture might lead to a problem.  The humidistat senses the moisture level (especially in winters) and provides passive ventilation for bringing humidity to an adequate state. 

However, the humidistat isn’t that important for many places. The absence of humidistat shouldn’t be a vital reason for dropping a worthy product. 


It’s a no-brainer why your solar attic fan should have utmost durability. After all, it’s going to face all types of weather throughout the year. And it shouldn’t make you worry at all. 

To ensure good durability you should have a keen look at the built-in material of your attic fan. Many reliable solar attic fans come with high-quality steel and metal to stand firm against the wind, rainfall and even hail too.

Some of the low-quality attic fans have plastic as their protective shield. This plastic does provide decent durability in summers but might become problematic during winter days.


The solar attic is one of the great examples of a simple but significant idea. Choosing the best product is a one-time effort to be worry-free about the heat. Moreover, I also believe that the list and buying guide has proved vital in this process.

If you’re still feeling dizzy regarding your final choice, you should have a look at my favourite. The New Light Solar Attic Fan has everything you’ll ever need in a solar fan. The coverage area is up to the mark and its metal body provides enough durability. Additionally, it also provides you with the option of mourning it on both the wall or roof.
