Buying Guide for Solar Attic Fans

Choosing the best solar company for your solar attic fan for you can be a tough decision. This part of the article aims to make the decision-making process easier for you by helping you understand what a solar attic fan is, its purpose, how it operates, its advantages over air conditioning systems, and its main parts. This buying guide also offers you some pointers on what to look out for in a solar attic and the factors to consider.

Why Do You Need a Solar Attic Fan?

During summer, when it is hottest, most attics can reach a temperature of up to 1500F. If the attic is not well ventilated or fitted with a powerful AC, the heat radiates throughout the house.

This increases the demand for cooling systems in the rest of the house, and consequently, the cost of air conditioning. The extreme heat can also lead to damage on the roofs. Besides, the high humidity during summer may lead to mold or mildew manifestation.

Even in sold seasons, the best solar attic fan can come in handy. They prevent ice damming, which could lead to mold manifestation or damage on the roof. Ice damming happens when snow lands on a fairly warm roof, causing it to melt. The melted snow water collects in the gutters and eaves and refreezes.

If this process happens frequently enough, the roof could get damaged, causing leakages. A solar attic fan pushes the excess moisture out of the attic and keeps the attic roofing cool to prevent ice from thawing.

Ultimately, it improves air circulation in the attic and throughout your home, no matter the season. Suppose you regularly use the rooms adjacent to the attic. In that case, you will notice a significant difference in the temperatures and quality of air in those rooms once you install a solar attic fan.

Advantages of Solar Attic Fan Over Air Conditioning

Below are some advantages that solar attic fans have over air conditioning:

  1. Solar attic fans are quiet. They do not make a loud noise when operating as most air conditioners do.
  2. They are cheaper. Solar attic fans are cheaper to buy, install, and maintain compared to air conditioning systems. Yet, they are effective in cooling the attic, as would air conditioners. Since they are operated on solar panels, they do not increase your cost of electricity. They also help in cooling the rest of the house, especially rooms adjacent to the attic. Therefore, reducing the amount of electricity used by cooling systems in those rooms.
  3. Easy to install. Unlike air conditioning systems that would require you to make significant changes to your electrical wiring and, in some cases, structural changes, solar attic fans are often quick and easy to install without elaborate wiring.

Other Benefits of the Best Solar Attic Fan

  • They are efficient. They adequately ventilate the attic. Moreover, some solar attic fans are thermostatically designed to automatically switch off when it is cooler and run when it is hot in the attic.
  • You may qualify for a tax credit incentive depending on your state’s regulations. Some states award members who are keen to go green to conserve energy. For instance, if you install an Energy Star-rated solar attic fan, you qualify for a 30% federal tax credit on the purchase price and installation cost.
  • They protect your property from damage. If excess heat accumulates in the attic for long, it can damage your roofing system from the inside.
  • Solar attic fans are safe. Electric attic fans are extremely powerful; therefore, they can pull carbon monoxide and other dangerous fumes from ground level gas appliances in your home. On the other hand, solar attic fans operate gently to push hot air out and allow cool air into the room.

Main Parts of a Solar Attic Fan

While different solar attic fans in the market have different specifications in terms of size, shape, weight, number of fan blades, material, etc., most of them have the following main parts:

  1. A photovoltaic solar panel that powers the fan
  2. Solar panel bracket or mount. It attaches the solar panel to the shroud. Can also be used to adjust the incline of the solar panel
  3. It houses the solar panel
  4. Shroud bracket. Attaches the shroud to the roof or gable
  5. DC motor. Transmits the solar energy to the motor
  6. Motor Isolation bracket. Separates the motor and the fan blades
  7. A high output fan blade. It moves the air in and out of the room
  8. Heavy-duty flashing. It is the bottom part of the shroud. It covers the fan blade and animal screen
  9. Some solar attic fans come with an automatic thermostat that allows you to preset the optimal temperature
  10. Protective animal screen. Keeps the debris, bugs, and small animals from entering the fan blade. Some solar attic panels have a protective screen while others do not

Factors to Consider When Choosing a Solar Attic Fan

There is no-one right solar attic fan for everyone. The right one will depend on your needs, conditions, and budget, among other factors. Below are some factors to put into consideration when determining the right solar attic fan for you.

  • Type of roof. Solar attic fans can be installed on the roof or gable. Roof-mounted fans are most suitable for flat and pitched roofs, while gable-mounted fans are best installed on already existing gables.
  • Size of your attic. To determine the appropriate size of the fan to buy, multiply 0.7 by the sq. ft of your home. The answer you get is the minimum cubic feet of air that the attic fan should move per minute.
  • Shape of the roof of the attic. A steep roof will require a more powerful fan to move the air compared to a flat roof.
  • Installation costs and expertise are involved. Generally, it is best to get a professional to install the solar attic fan for you. However, gable solar attic fans are easy to install and may cost less than installing roof attic fans.
  • Where to position the solar attic fan. Since the solar attic fans are powered by solar energy, you want the solar panel to be installed in a site where it receives maximum exposure to the sun during the day. This keeps the panel operating effectively throughout the day.

Key Features to Look Out For in a Solar Attic Fan

Here are some important features that look out for in solar attic fans:

  1. Adjustable solar panel bracket. An adjustable solar panel ensures that you can adjust its inclination angle for maximum exposure to UV rays and sunlight.
  2. Durability. Since the solar panel will be installed on the roof, it will be exposed to extreme weather conditions, including UV radiation, rain, thunderstorm, strong winds, snow, hailstones, and hurricanes. Ensure you go for construction materials that are high durability, impact-resistant, waterproof, and corrosion-resistant.
  3. Availability of solar attic replacement parts. When buying any equipment, we hope that it serves us for many years without getting damaged. Unfortunately, that is not always the case. However, if parts of the solar attic fan get damaged, you want to be able to find replacement parts easily. Check the manufacturer’s website to ensure that they sell spare parts too. Alternatively, go for a solar attic fan that has a warranty that covers repairs and replacements.
  4. Versatility. The solar attic fan should fit well in different roofing systems. Some solar attic fans are designed for use in a wide range of spaces, including boats, garages, sheds, outdoors, and greenhouses.
  5. Quick and easy to install. Go for a solar attic fan that can be installed in a few steps without needing major changes in your house’s structure or electrical wiring.
  6. High-performance fan blade The ideal solar fan attic utilizes solar energy efficiently for optimal functionality. The more the fan blades, the more powerful the solar fan attic. Besides, if your attic is big, go for a solar attic fan with high cfm.
  7. Has a warranty. A comprehensive warranty that offers coverage for a longer period is a sign that the attic is reliable and durable. Keenly check what the warranty covers.
  8. Qualifies for federal solar tax credits. It will save you some money on the price and installation costs.
  9. Highly rated and has numerous positive reviews. Check the product’s reviews across different platforms to determine if the solar attic fan you are considering is credible.

If you are not clear on which solar attic fan to go for and its specifications, it is best to consult with a professional who will do a site survey and recommend the best type of attic fan to consider.

A solar attic fan will significantly lower your air conditioning bills while ensuring that your attic remains well ventilated and cool. Use the reviews and guidelines provided above to choose the most suitable solar attic fan for you, and you might qualify for a solar tax credit.

Benefits of Attic Venting

Attic venting is an important aspect of maintaining a healthy, energy efficient home
Is Insufficient Attic Venting Destroying Your Home?

Attic venting is an important aspect of maintaining a healthy, energy efficient home. The Natural Light Solar Attic Fan works with your existing passive vents to improve air circulation. Adding a solar attic fan is a simple and affordable home improvement product that overtime will pay for itself. Cooling your attic space in the summer can reduce your AC costs. It will also extend the life of your roof shingles and prevent damaging rot and ice damming.

Attic Venting Extends the Life of Your Roof

The most obvious reason for attic ventilation is to lower the attic temperature during the warmer months. Attic temperatures can exceed 160°F during hot summer days. Proper attic ventilation can reduce those temperatures by up to 40°F. No matter how much insulation is in the attic, heat can still transfer into adjacent living spaces. In fact, extra insulation can actually add to temperature increases because heat is trapped in the insulation. Proper ventilation removes this excess heat build-up. As the heat is exhausted, the workload of your air conditioning system is reduced, thereby saving energy costs and even extending the life of your air conditioning system.

Reduces the Load on Your HVAC System

Though asphalt shingles are designed to take the abuse of the sun for many years, they are subjected to greater temperatures when the roof decking is allowed to overheat, which is just what happens in an under ventilated attic. In fact, asphalt shingle manufacturers warranties require proper attic ventilation. During the colder months, attic ventilation removes the warm, moist air that heat sources produce. Hot moist air lingering in the attic spaces can condense on the underside of the roof sheathing and rot it out. Moisture in the attic also causes mold to develop on the interior walls. Cold air in the attic space will not affect the temperature in the adjacent living spaces if properly insulated.

Reduces Moisture Build-up in the Attic

In the cooler months, moisture is the most serious concern. Even with the use of vapor barriers to keep moisture from entering the attic, there are air leaks around ceiling light fixtures, bathroom exhaust fans that allow unwanted moisture into the attic. Moisture condensing on the framing members and the inside of the roof deck can lead to the growth of mold, mildew and rot in the roof deck and framing. A good indicator of a moisture problem is rusty roof nails sticking through the roof deck.

Attic Venting Benefits:
  • Eco-friendly
  • Saves AC cooling costs
  • Extends life of roof shingles
  • Reduces moisture build-up
  • Increases air circulation

Enhanced design will ventilate up to 4300 square feet of attic space with a single fan. The fan produces a smoother air flow and increases exhaust performance by up to 30% from previous models. This next generation solar powered attic fan is our most powerful and efficient model yet.

Remove heat and moisture, reduce energy usage, protect your home and roof and reduce premature aging of roof shingles with the addition of a roof or gable-mounted Solar Attic Fan.

Cools your attic and reduces energy usage in the summer months

The Professional Series Solar Powered Attic Fan 9930TR effectively reduces attic heat build-up in the summer months and moisture in the winter months. With 43% of air conditioning base on high attic temperatures frequently up to 160F, lowering attic heat typically lowers air conditioning run-time.

Installing a Solar Powered Attic Fan will help remove the heat build-up in your attic and bring your attic’s temperature down closer to the ambient outside temperature.

The reduction in attic temperature will also benefit the homeowner by preserving and extending the life of the roofing and attic construction materials. Additionally, hot air in your attic can then heat the metal exterior of your HVAC ductwork and consequently heat the air passing through it, causing your air conditioner to work even harder.

Solar Attic Fan

Removes moisture and reduces mold in the winter months

Solar Attic Fan

In the winter months, the building materials in your attic can absorb up to 28 gallons of moisture, contributing to mold and mildew growth. Moisture migrates into the attic space from daily activities such as running the dishwasher, showers and cooking. Additionally, warm attic air meeting the cold roofing materials creates condensation, which drips onto the attic insulation causing it to lose its effectiveness. Warm attics in winter also contribute to ice damming as the snow melts on the roof and re-freezes at the eaves, causing water to accumulate.

Installing a Solar Powered Attic Fan will allow for better air flow and moisture control inside your attic and prevent the condensation which can lead to mold and mildew problems.

Florida Solar Retrofit Fan

Aura Solar Fan Retrofit Vent Cap
Rendering of 12 in. Aura Solar Attic Fan Retrofit

The Florida Solar Fan Retrofits are designed to replace existing roof vents.

Florida Solar Fans are a perfect replacement for Roof Wind Turbines which frequently stop working because of corrosion. The Florida Solar Gravity Retrofit does not need to spin in order to provide excellent ventilation. Instead, it exhausts heat using both solar and wind power. It also works passively by using the Venturi Effect which happens when wind blows against the outer louvers. As a result, this creates an upward draft allowing air to freely flow in and out of the vent.

The vertical louvers continually exhaust air while preventing rain and snow from entering. The vertical louvers also keep out insects and animals allowing for optimal air flow. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph.

The Florida Solar removes hot air in the summer and moisture from the attic in the winter to provide optimal ventilation. The Retrofit Vent head will fit over an existing base of the same diameter.  This allows for quick and easy installation. Upgrade and make your roof ventilation maintenance free.

Easy to install, Florida Gravity Solar Fans do not need to be leveled or balanced like old roof turbines.

Roof turbine parts wear out, even if they are balanced perfectly. If a roof turbine is making noise, it is slowing down because it is wearing out. When it slows down, it is likely to start allowing rain and snow into the attic. All Solar Fans come with a 1-Year Warranty.

Apollo 11 Replica


Ventilated with the Pop Vent


The Pop Vent is more than a roof vent; it’s also a cool way to ventilate a really fun art project. Los Angeles-based composer, Chad Fischer, built a replica Apollo 11 Space Capsule in his garage during quarantine. 



This incredibly beautiful and realistic model is now a playhouse for his daughter.




Chad installed the Pop Vent to ensure that his child played in a safe well-ventilated space. 



He also knowingly chose The Pop Vent because of its aerodynamic shape; he knew it would make for a great looking installation.  




AVP’s vents can withstand wind speeds in excess of 200 mph while also keeping out wildlife, insects and rain. As a result, the pop vent will protect the playhouse for years to come. 




To the right, you see images of this one-of-a-kind playhouse as well as part of the assembly process.

This solar panel produces enough electricity to power a spinning fan in the round ventilator on the roof at the top of the photo. See it? But the fan only works when the panel is basking in sunlight. The fan does not lower the temperature in the attic at all. I feel solar fans are a waste of money. Copyright 2022 David Wolfe


“But after seeing my solar-powered attic fan work, I have a long list of cons.”

Solar Powered Attic Fan Checklist


  • fans don’t move lots of air


  • fans slow down or stop when most needed


  • there may never be an ROI!


In David’s July 7, 2019 Newsletter, he ponders on why solar-powered attic fans are, for the most part, hype and a classic case of an emotional fuzzy-feel home improvement purchase in all too many cases.


DEAR David: My attic space gets as hot as blue blazes. I saw an advertisement for a solar-powered attic fan and that seems like a great way to remove heat and reduce my carbon footprint.


Do these fans really work, and are they hard to install? Will the fan significantly reduce the temperature inside my attic? What are the pros and cons to these solar attic fans? Brad L., Tampa, Fl


DEAR BRAD: I installed a solar-powered attic fan last year to see how well it would work. The installation went like clockwork.


When is The Best Time to Install the Fan?


I had decided to do the work early in the morning while it was cool on the roof. Within an hour after installing it, the sun hit the solar panel and the fan blades started to spin. It was almost magical to see the solar attic fan work.


You’re a pretty clever guy to get the sun to do double duty. It makes perfect sense to make the sun cool your attic space, since it is the source of the problem in the first place.


Free & Fast Bids


Are Solar Attic Fans Really Earth-Friendly?


As for reducing your carbon footprint by not using electricity from a power plant, I can’t tell you if the solar fan you might buy will be that environmentally friendly. The manufacturing process used to make your solar fan might actually be quite carbon positive. But in any event, you might be doing the right thing by trying to use a solar-powered fan.



Are There Pros and Cons to Solar Powered Attic Fans?


There are pros and cons to solar-powered attic fans. Here’s a list:


  • they work for free using the suns rays


  • they do exhaust some hot air


  • the solar fans do not require the services of an electrician to connect


  • they are also very quiet


What are the Cons?


But after seeing my solar-powered attic fan work, I have a long list of cons:


  • My fan only works when it is getting direct sunlight on the solar panel


  • If a cloud drifts through the sky blocking out the sun, the fan stops spinning immediately


  • As the sun sets, the attic is still hot and my solar fan stops spinning


  • The fan I have moves only 800 cubic feet of air per minute (CFM) when the sun is shining directly on the solar panel

Does the Fan Spin at Different Speeds?


Yes, the solar powered attic fans spin at different speeds.


If the angle of the sun is lower in the sky (morning and late afternoon) or the sun’s rays are trying to cut through thin clouds or haze, the fan spins slower moving less air.


The single solar-powered attic fan I have has not lowered the temperature in my attic at all. I took precise before and after temperature readings.



How Much Air Must Move Through the Fan To Cool an Attic?

This is an infrared photo of my own roof. See the white crosshairs and temperature reading? 155F That’s blazing hot and it’s possible it can go as high as 170 F. The entire inside of the attic can reach this temperature. Copyright 2022 David Wolfe




Chicken growers know all about this. Chicken farms in any area of the world that gets hot MUST HAVE enormous fans moving tens, perhaps hundreds, of thousands of CFM of air through the growing houses to keep the chickens alive in hot weather.


It’s all about moving vast amounts of air in your attic if you want to lower the


Attic temperatures in the summer on a hot day can easily get to 140 F. In late June early July with the sun passing through the least amount of atmosphere in the Northern Hemisphere, an attic could get up to 160 F, or more.


How Many Solar Fans Do I Need to Cool my Attic?


If you are going to go solar, I urge you to by several solar-powered attic fans. You will need them. You may need fifteen or more to move thousands of CFM of air through your attic.


Where Should the Solar Panel be Located?


The solar panel should be located away from the actual fan. In the Northern Hemisphere, you want the solar fan pointing due south.



My solar fan has this neat feature. This allowed me to put my solar fan on the rear portion of my roof so you don’t see it from the street, while the solar panel is on the part of my roof that faces due south.


Should the Fans be in Direct Sunlight?


You want the solar panels located on the roof where they will not be shaded by trees, and where they will get direct solar power from Noon until sunset. This is the hottest part of the day, that part where you need the fan blades spinning at full speed.


Do I Have to Cut a Hole in My Roof?


Solar-powered attic fans require a hole to be cut in the roof, possibly two if you purchase one that has the remote-panel location feature. If you do not know how to properly flash these fan housings into the roof shingles, then you should hire a qualified roofer.


It’s not hard to do the work, but there are very important steps that must be followed to have a leak-proof installation.


Do These Fans Require Caulk?


When installed properly on a roof with standard asphalt shingles, solar-powered attic fans do not require caulk, roofing cement or any other product to prevent leaks. A great roofer will cut the shingles and lace the fan housing into the shingles so that rain will stay outdoors where it belongs.


How Much Air at a Minimum Needs to Move Through My Attic?


If your attic space is over 1,800 square feet, you will need enough solar fans to move 8,000 CFM. You need that amount of air, if not more, to get any sort of cooling benefit from the fans.


Intense sunlight can create heat faster than one or two small fans can cool an area. If you want to see how to properly cool attic spaces, visit a chicken farm. These farmers use giant fans that move tens of thousands of CFM of air that keep the chickens alive.

Whole house fans – This is not one. This is an attic fan but can also be called a powered attic ventilator (PAV). They are often visible on the outside of a house either on the roof or on a side wall of an attic gable. Whole-house fans are located inside homes. Both perform entirely different functions. Copyright 2022 David Wolfe

“A whole-house fan is a fixture that is often located in the ceiling of a home. In rare occasions, they can be located in a wall.”


Whole House & Attic Fan Checklist


  • Whole house fans cool you AND your attic


  • Attic fans only cool the attic – AVOID solar attic fans!


  • Both fans need lots of NET FREE AREA to push out hot air


  • For best cooling, you need both types of fan in your home


DEAR David: What’s the difference between a whole-house fan and an attic fan? Which is the best one to have in a home?



What’s the best way to cool a home using these fans? Can either of these fans cause problems? Jon Solaris, Orlando, Florida



DEAR John: Whole-house fans and attic fans are as different as apples and watermelons.


What’s the Difference Between a Whole House and Attic Fan?


Both fans move air just as apples and watermelons are both fruit, but the similarities end there.


What are Whole-House Fans?


A whole-house fan is a fixture that is often located in the ceiling of a home. In rare occasions, they can be located in a wall.

It turns out the motor was the issue! Copyright 2022 David Wolfe

Where are Whole House Fans Located?


A whole house fan might be in a hallway or some other central location of the home. The fan is always located on the highest ceiling or wall and oriented so that it blows air directly into an attic space.



This is a typical whole house fan. It can be set horizontally as you see here or vertically in a side wall.

The whole-house fans cool you because they pull air through open windows and doors in your home. The breeze in a house can be significant depending on how many windows you open and where they are in relationship to the fan.



Does a Whole House Fan Move Lots of Air?


A typical whole-house fan moves vast amounts of air. The blades of the fan can be large, and they can have significant pitch so they can move thousands of cubic feet of air per minute.


Turn one of these bad boys on inside an average-sized ranch home that has 2,400 square feet of finished floor space, and you can replace every bit of stale, hot inside air with cooler outside air in less than five minutes.


Do They Push Air Through an Attic?


These fans are designed to pull air through a house and exhaust the air by pushing it through an attic space. Since you live in an area that has low humidity, they are superb and highly efficient cooling devices.


They work best when they are operated in the early evening or night hours as outdoor temperatures start to nosedive and the inside air temperature of a house is still high. As outdoor humidity rises, the cooling effect from whole-house fans drops.

What are Attic Fans?


An attic fan is completely different. These are smaller fans designed to move hundreds of cubic feet of air per minute out of your attic area only. These are mounted to the surface of your roof in most cases looking like a small space ship has landed on your home.


This is a typical attic fan. It just mounts up on your roof. You need to run 120-volt electric to it to power it. Do NOT get the solar-powered fans. They’re WORTHLESS as they don’t move air when you really need it late in the day. CLICK THE PHOTO NOW TO SEE ALL THE DIFFERENT TYPES OF ATTIC FANS SO YOU CAN HAVE ONE OR TWO DELIVERED TO YOUR HOME IN DAYS.

In some cases, the fans can be mounted INSIDE your attic on a vertical gable wall. You then see a louvered vent in your gable wall.




Do Attic Fans Move Air Through a House?


No, these fans are not supposed to move air through your home. They only move air through an attic space above where you are.


The cooling principle here is simple: If you replace the extreme hot air inside an attic that might be 140-160F with air that is 85-95F, the inside of your home should also be cooler.


How Long Does it Take To Cool the Attic?


The issue is it can take many hours before the attic lumber and insulation cools enough that you might feel a difference down inside your home.

The heat gain from extremely hot ceilings adjacent to hot attics can stress air-conditioning systems, and push them to the limits of their ability to cool a home.


Where do the Fans Exhaust the Air?


For both fans to work properly, they need to easily exhaust the air to the outdoors. The attic fans do this by default, as you typically have to cut an opening in the roof or a side wall of an attic to mount the fan. When installing a whole-house fan, you need to install several static pot vents in the roof that allow air to get out.

You can also install very large gable vents if your home design permits this. The whole-house fans come with instructions that tell you how much NET FREE SPACE of ventilation you need so the fan works properly.


Do the Fans Need Lots of Intake Air?


The attic fans also need lots of intake air vents along the lower edges of the roof. Continuous soffit venting is the best and the air from the outdoors needs to be able to easily enter the lower reaches of the attic where the roof passes over the outside walls of the house.

Since most attic fans are located high up on a roof, this design allows for excellent cross ventilation of the entire attic space.


Can Attic Fans Can Rob Air From Home?


If you don’t provide enough intake air vents for attic fans, they can draw air from inside your home. This happens because the moving blades of the fan create a partial vacuum.

It’s not a good idea to send cool air from the inside of your home up into an attic, since you are paying good money to cool inside air with an air conditioner.


Do Whole House Fans Need Lots of Vent Space?


Whole-house fans also need plenty of exhaust air vents through the roof or through side gable walls of attics. Each whole-house fan manufacturer tells you for each size fan how much net-free area of exhaust ventilation the fan requires to work properly. If you don’t provide this exhaust ventilation area, the fan blades will spin, but not move the maximum amount of air.


Do Both Fans Remove Hot Attic Air?


Whole-house fans serve double duty as they remove hot air from the attic as they work. But you do not necessarily want the whole-house fan operating in the middle of the day as your attic heats up.



IMPORTANT TIP: For this reason, it makes sense to have both types of fans in a house. They operate at different times of day and night, since they are designed for two different purposes.


Whole-house fans work so well, they are often equipped with timers. If you operate one all night long, you might need to sleep with blankets. They often can cool a house to a comfortable temperature in just several hours.


What Windows Should Be Open With a Whole House Fan?


You can get concentrated cooling with a whole-house fan by opening the windows in selected rooms. As the fan operates, it creates a comfortable breeze in the rooms with open windows.


Should You Close Fireplace Dampers?


Be sure you do open windows before you turn on a whole-house fan. If you don’t and you have a fireplace with ashes in it, you will create an ash storm as air is sucked down the chimney and rushes across the dry fireplace ashes.


The dirty ashes are then broadcast through the house as they are sucked towards the whole-house fan. How do I know this? It’s the voice of experience talking.
