10 BEST Solar Attic Fans in 2021

A good solar attic fan may reduce the temperature in your attic by up to 10 degrees Fahrenheit. As a result, you will have the ideal room temperature without being bothered. Furthermore, a solar attic fan is a low-cost, onetime investment that will endure for decades before needing to be replaced.

The only catch is that not every attic fan is constructed in the same way. It’s possible that some of them may fall short of your aspirations. Don’t be concerned, though. We’ve got you covered.

We’ve compiled a list of the BEST solar attic fans on the market after conducting extensive research. This list will assist you in generating business without making a mess.

Things to look for in “Solar Attic Fans”

  • Gable Positioned vs. Roof-Mounted

Different strategies for preventing overheating are required for different attics, garages, and conservatories. The same is true when installing a solar attic fan. There are two types of solar attic fans: roof-mounted and gable installed.

This provides you the freedom to install a solar attic fan based on your requirements and region. Please let us know which option is best for you.

The roof-mounted fan, as the name implies, necessitates the installation of a roof vent. To keep the roof looking nice, the remaining vent is mainly hidden by the shingle when it’s installed properly.

Because the solar panel is usually fitted with these fans, they do not require a long wire. As a result, it receives the maximum amount of sunlight, resulting in greater inefficiency.

On the other hand, a gable-mounted solar panel is linked through a solar panel and can be put in a desirable wall/gable. They’re simple to install and less expensive than roof-mounted attic fans.

  • Coverage Area

The first thing to think about is the area that your solar attic fan will cover. The main rule is that it should be larger than the space in your attic or garage. Assuring that the bottom line maintains the ideal temperature even during summer extreme weather events.

Solar attic fans are available with a variety of motors. As a result, they have unique coverage areas. For specific capacity, look at the motor’s wattage, fan speed (CFM), and area coverage of the solar fan.

Bear in mind that the higher these numbers go, the more expensive the fan would be. A high-watt motor also necessitates higher energy usage.

  • Humidistat and Thermostat

The thermostat and humidistat aren’t required in this room. They will, however, play a role in keeping the ideal temperature and humidity for your targeted region.

The thermostat allows the fan to better understand the temperature of its surroundings. As a result, anytime the temperature rises, the fan will automatically start blowing. This also keeps the fan from operating inefficiently during the winter or monsoon seasons.

Many solar attic fans come pre-programmed with a thermostat, although many manufacturers sell it separately.

Maintaining the ideal humidity level is a continuous analytical procedure. Both higher and lower moisture levels might cause issues. The humidistat detects moisture levels (particularly in the winter) and delivers passive ventilation to maintain an appropriate humidity level.

The humidistat, on the other hand, isn’t necessary for many areas. The lack of a humidistat should not be a compelling cause to discard a worthwhile product.

  • Longevity

It should go without saying that your solar attic fan should be extremely durable. After all, it will be exposed to various weather throughout the year. It also shouldn’t cause you any concern.

Your attic fan’s built-in material should be examined carefully for long-term durability. Many dependable solar attic fans are composed of strong steel and aluminum to withstand wind, rain, and even hail.

Plastic is used as a protective cover on certain low-quality attic fans. In the summer, this material is rather durable, but in the winter, it may become troublesome.

What do we mean by solar attic fans?

Solar attic vent fans use the sun’s energy to draw hot air out of your attic and exchange it with cooler outdoor air. The amount of time and effort your HVAC system needs to undertake to chill your upstairs living area is reduced as a result.

Why use solar attic fans?

Solar attic fans function to reduce attic temperature by pushing hot, stuffy air out of the attic and boosting circulation. Lesser rooms and inhabitants in your house will look better and more pleasant if the attic heat is controlled. It helps in following-

  • You may save money by using solar attic fans.
  • Solar attic fans keep your house safe.
  • Solar attic fans might help you save money on electricity.
  • Solar attic fans are completely risk-free.

How do they work?

Here are the following steps of how it works-

  1. Heat Accumulates In An Attic That Isn’t Properly Ventilated

The sun shines down on a house’s roof, heating up the attic. Passive vents (soffit or gable) give some airflow but not enough pressure to drive hot air out.

  1. A solar attic fan provides air circulation.

The solar attic fan’s pv module absorbs sunlight, which fuels the fan’s motor, which increases air flow.

  1. Air circulation transports hot air from the attic.

Improved air circulation creates the necessary pressure to drive hot air out of your attic. Attic ventilation may reduce the temperature in your attic by up to 40 degrees!

Are Solar attic Fans really worth it?

The solar attic fans all circulated less than 1,000 cubic feet of air per minute (CFM) and did little to cool the attic. The sun’s thermal beams are quite strong. They may heat up over your roof to above 160 degrees Fahrenheit.

Whether that’s worth buying an item relies on your requirements and motives, just like any other purchase.

When you don’t currently have an attic fan and want to install one just to save money on your energy bill, you’ll likely save more money on a separate platform.

Installing the solar attic fan to substitute your electrical attic fan is definitely worthwhile. Solar attic fans are a low-cost alternative to conventional home improvement solutions for cooling your attic.

Pros and cons of Solar attic fans


  • In the Summer, Keep Your Attic Cooler — Heat accumulation in your attic, especially in warmer areas like Florida, not only travels to the living spaces below, but may also harm your roof, insulating, and structural stability of your home. As a result of the increased heat, your air conditioner has to work harder, resulting in higher electricity costs.
  • Decrease Attic Moisture – Summer’s warmth and humidity may contribute to the development of fungus and molds in your attic, and also cause physical damage to your home.
  • Solar attic fans are ecologically beneficial since they use the sun’s energy instead of electricity. The solar attic fan, as a sustainable source of energy, will help you decrease your environmental impact while also saving money.
  • Solar power, also known as solar electricity, is utilized by the solar attic fan to force hot air out of your attic, which is not only free but may also help you save money on energy costs. These blades are also low-maintenance and simple to establish. You shouldn’t need to operate an attic fan on cloudy days, and with solar attic fans, you only use the energy you need from the warmest, hottest days of each year, at no additional cost.
  • A Fantastic Investment — With more than 250 days of sunlight on average in Florida, a solar attic fan is a good investment to make your house more pleasant while also lowering your energy bills. Solar attic fans also add curb appeal, with a sleek, reduced look that demonstrates environmental awareness and energy savings.


  • Conventional Models are More Expensive – Solar attic fans are more expensive upfront than regular attic fans, but the initial cost is offset over time by energy savings.
  • Most Homes Will Require Two — To circulate air and save money, most homes will require two solar attic fans.
  • Solar Attic Fans Need Clear Sunshine — Because the sun as their energy source, solar attic fans require direct sunlight to function. To work, your solar panel will have to be in bright sun, which might be hampered by cloud cover, mature trees, and even dirt.

Tips and tricks to use Solar Attic Fans

You could be going to purchase and install an attic fan, but nobody really wants to invest in a home improvement project they don’t fully understand. Here are our top six recommendations to remember in order to fully understand the topic, “How do attic fans work?”

The #1 Way “How Attic Fans Work” is to remove hot air.

Because of the sun’s heat leaking through the roof, your attic is always the warmest place in your house. Too much heat in the attic can leak down into your living rooms, which isn’t generally a concern.

An attic fan prevents the heat from rising to the point where it can spread. It increases the quantity of hot air evacuated from your attic and transported outdoors where it won’t bother you during the warmer Spring and Summer months.

  1. Bringing in Fresh Air

The process of releasing hot air and drawing in cold air is already built into your attic, but an attic fan speeds up and enhances it.

The number of fans you’ll need will be determined by the size of your attic, the climate you live in, and other considerations described further down.

  1. An Attic Fan Performs Best When There Is Enough Airflow

When understanding how to cool an attic, anybody wondering “how does an attic fan function” must first understand the importance of ventilation.

If your attic has little ventilation and hot air may easily become trapped, the attic fan will have to work hard to remove the undesirable air, wasting energy in the process.

  1. Attic fans are only effective if there are seals in the attic.

While it’s true that attic ventilation fans, like AC units, require enough airflow, they also require adequate seals. Another important piece of the puzzle in figuring out “how do attics fans function?” is to understand how they work.

You will not run your air conditioner all day with all your windows open, would you?

Certainly not! If the space between your attic, roof, and the rest of your living space isn’t sealed, the fan will rapidly become a nuisance.

The adjustable humidity and temperature parameters from these attic fans might lead to an overheated machine if the seals among your attic, roof, and living space aren’t good enough.

  1. It Doesn’t Matter How Big Your Fan Is

Attic fans with larger blades may impact more air than those with smaller blades. Just remember that there is such a thing as too much of a good thing. If your fan is more strong than it needs to be, it may have an impact on airflow throughout your home.

  1. It Only Has to Work When It Is Required

Treat your attic fans the same way you would any other fan in your home. Its duty is to keep the attic cool, especially during the hotter months of the year.

During the colder months, just use it sparingly. Attic fans may help to remove moisture accumulation that could contribute to mold, and they don’t have to operate for very long to do so.

Some of the best solar attic fans feature a built-in thermostat that turns on only when the temperature reaches a specific level. This will prevent you from having to repeatedly climb into the attic even while guaranteeing that your main house temperature is maintained.

Solar energy, on the other hand, isn’t suitable for everyone (yet), so be sure it’s suited for you.

Frequently Asked Questions (FAQs)

  • Are Attic Fans Really Beneficial?

Yes, attic fans are really beneficial! Attic fans, as per the Renewable Energy Laboratory (National Renewable Energy Laboratory, may decrease the concentration in your attic by 10 to 25 degrees. Convection causes heat to rise, and attic fans function by pushing hot air out of your home and pulling cooler air in from outside.

Pairing attic fans with appropriate insulation and attic air-sealing can help keep your house cool while also saving money on energy bills.

  • Are solar attic fans cost-effective?

Solar attic fans do, in fact, save money! We’ve all heard the saying, “If anything seems too authentic, it probably is.” While this is generally the case, it isn’t with solar attic fans. Solar attic fans, according to recent research, can help you save money in a variety of ways. They have the ability to:

1) Reduce the burden on your air conditioner to extend its life.

2) Keep your roof cool and dry by removing excess heat and moisture.

3) Lower your utility expenses by cooling your attic with less power.

4) It is significantly less expensive than putting a second air conditioner in your home.

Installing the solar attic fan has advantages and disadvantages, but it’s well worth the initial investment when you calculate the annual savings.

  • How many solar attic fans do I need?

“It varies depending,” is the quick response. The basic answer is that a variety of factors influence the number of fans you’ll require. The size of your house, existing air conditioning, the pitch of your roof, attic soundproofing and sealing, or whether or not you have sloped roofs all play a role.


The solar attic is a fantastic example of a simple yet powerful concept. Selecting the finest product is a onetime investment in not having to worry about the heat. Furthermore, I feel that the list and shopping guide had an important role in this process.

If you’re still unsure about your ultimate decision, have a peek at my personal favorite. The New Light Solar Attic Fan offers all the features you might want in a solar fan.
