The Best Solar Attic Fans

Summer is here, and the warmer (or hotter) weather is upon us. Everybody is going to want a way to stay cool, but not everybody is going to want to rack up the electric bill or increase their carbon footprint by blasting the AC around the clock. If you’re looking for a cheaper and greener alternative to beat the heat, then a solar-powered attic fan is a great investment for you. We all know how stuffy attics can get, so you’ll definitely need a good solar attic fan to get to cool things down. Luckily, that’s exactly what we’re here for. We want to help you avoid a sweaty summer so you can actually enjoy the warmer weather.

Carry on reading to see our full list of the best solar attic fans, followed by a recap breaking down what makes each product on our list stand out. Or jump straight to our number #1 pick here.

What Should You Look For in a Solar Attic Fan?

The first step to any purchase is learning what to look for. Before you even think about buying a solar attic fan, you need to learn what separates the good solar attic fans from the bad ones. In pursuit of that goal, we’ve made a short and simple rubric that will detail the criteria we used while evaluating the best solar attic fans. This will help you understand our thought process and even conduct your own further research if we can’t help you find the best solar attic fan for you. In just a few short paragraphs, you’ll be a certified expert in solar-powered attic fans.

Criteria #1: Cooling Capacity – A fan, solar-powered or otherwise, that doesn’t cool things down is… bad. Obviously how cool you need things to get will be based on your attic and your preferences, but it’s probably better to err on the side of the cooler the better. Cooling capacity is measured in cubic feet, so a quick measurement of your attic will give you a good idea of what exactly you’re looking for. We’re going to give you all the relevant information and make sure you find the best solo attic fan that’s perfect for your specific attic.

Criteria #2: Design – A powerful fan that’s annoying to use and install isn’t really all that great. We want to find a solar attic fan that gives you a simple, streamlined experience so it can make your life easier as well as cooler. The best solar attic fan will have an adjustable solar panel so that it’s always getting the most sunlight, and a lot of blades so that it’s nice and quiet, as well as some other extra features to make everything run that much more smoothly. A good design is about much more than pretty packaging.

Criteria #3: Size – Size matters, but bigger isn’t always better. The size you want from your fan will largely depend on the size of your window, but it’ll also be partially preference. You can usually assume that a larger fan will be stronger, but it’ll also be more of a hassle to move around and install. I can’t decide for you what size is best, but we’ll make sure to include the full measurements of every fan on our list. We want to make sure you know everything you need to know to make the best purchase for your home.

Criteria #4: Price – We’re not here to make you spend a ton of money for no reason. Meeting this criterion is less about being cheap and more about justifying your price. We’d rather buy an expensive product that’s cheaper than it should be than waste money on a cheaper product that isn’t worth the money and that will just break on you or not perform well. That being said, it’s important to mention that even if you get one of the cheaper options, you’re going to have to spend a decent amount of money on your new solar attic fan. The good news is that the price spectrum isn’t all that wide until you get to the extreme ends, so if you’re looking at the mid-tier products, you’ll be able to ignore the dollar sign and just pick the product you prefer.

Here’s How We’ve Determined the Best Solar Attic Fans

We measured the specs of the top products on the market against our listed criteria to see how they held up and if they’re worth buying. We then checked customer reviews, blog posts, and “best solar attic fans” articles to see if the products on our list performed as advertised. We’ll also make sure to include a wide variety of products that covers different niches and price points. This way, everyone can find the perfect product that will satisfy their needs and their budget.

And without further ado, here is our list – tailored to your specific needs – of the best solar attic fans. 

#1: Remington Solar Attic Fan (Best Value – All-Purpose)

To get things started, we have the Remington Solar Attic Fan nabbing our top spot as the best solar attic fan. This high-quality solar attic fan is on multiple lists of the best solar-powered attic fans, so you know you’re getting a reliable product that passed the popularity test.

Our top-ranked solar attic fan boasts a strong 30-watt motor that’s guaranteed to cool things down in a hurry, and it claims a cooling capacity of 2,200 square feet. Even the biggest attics out there will be ice cold before you know it.

The Remington Solar Attic Fan’s solar panel is adjustable, so you’ll have no problem getting the perfect angle for optimal performance no matter where you live or no matter what time of year or day it is. Our number one solar attic fan has measurements of 22 x 22 x 11 inches and a weight of about 19 pounds, so it’s definitely not exactly pocket-sized, but it’s decently small compared to some of the other solar-powered attic fans out there.

It also features a brushless motor that’s sure to be whisper-quiet. It comes with all of the necessary parts for assembly plus a humidistat and thermostat, so you can make sure that your attic is your own personal micro-climate that’s always to your liking. On top of everything, the Remington Solar Attic Fan is nice and easy to install.

As we mentioned earlier, the Remington Solar Attic Fan is a real crowd favorite that’s on all of the lists of the best solar-powered attic fans. It’s earned the approval of the masses thanks to its easy-to-install design, its powerful and quiet motor, and its sleek design. Of course, the limited lifetime warranty and the 30-day money-back guarantee definitely don’t hurt either, and they really add to the value of the Remington Solar Attic Fan.

Put a reasonable price tag on that and all of a sudden you have yourself the best value on the market, and that’s why the Remington Solar Attic Fan was an easy choice for us as the best solar attic fan.

#2: Natural Light 24W Solar Attic Fan (Best Overall Solar Attic Fan)

Replace Image below with Amazon SiteStripe Image

A lot of customers might have looked at the Remington Solar Attic Fan and thought that it pushed the boundaries of what they’re willing to spend. Of course, other customers might have decided that they’re willing to go beyond that if it means walking away with a better product. If you fall into the second category and you’re the kind of customer who won’t settle for anything but the best, then you’ll have to check out the Natural Light 24W Solar Attic Fan.

This heavy-duty solar attic fan might be a bit more expensive than our number one fan, but, as the saying goes, you get what you pay for. Keep reading to find out more about the big selling points that might just convince you to max out your credit card and treat yourself to the Natural Light 24W Solar Attic Fan.

Reason #1 to Choose This Product: IP68 Waterproofing

Thanks to the IP68-rating waterproofing of the Natural Light 24W Solar Attic Fan, you never have to worry about a little rain damaging your expensive new fan. This premium-grade solar attic fan is also dustproof and just overall weather-resistant, so it’s really going to be able to stay with you for the long haul. I wouldn’t be at all surprised if this fan ends up sticking with you until you move to a different home or retire down in Florida. Get a solar attic fan that can stand up to the elements and buy the Natural Light 24W Solar Attic Fan.

Reason #2 to Choose This Product: The Sturdiest Material

There are things much more damaging out there than a little water, but the Natural Light 24W Solar Attic Fan is more than just waterproof. If you really need to make sure your solar-powered attic fan will be the last one you ever buy, then you’ll want the sturdy aluminum frame that the Natural Light 24W Solar Attic Fan offers. And if this fan does somehow break on you, it’ll be covered by the 25-year warranty. The bottom line is that it’s impossible to find a truly cheap solar attic fan, so it’s a good idea to make sure you won’t be replacing your new fan any time soon. Thankfully, that’s what the Natural Light 24W Solar Attic Fan is here for.

On top of the waterproof, dustproof, and overall nearly indestructible design of the Natural Light 24W Solar Attic Fan, this top-notch fan is compatable with all sorts of different roof materials whether they’re slanted or flat. It has an amazing cooling capacity of 2625 square feet. It has a size of 27.25 x 27.25 x 11 inches and a weight of 29 pounds.

Other than the price, the big detracting quality of the Natural Light 24W Solar Attic Fan is that none of the more leisurely features – like a thermostat and a humidistat – come included, though they are available to be purchased separately. So if you want something a little more streamlined, then you’ll probably prefer the Remington Solar Attic Fan. But if you want a more powerful machine that will keep on trucking for years to come, then you’ll have to break the bank and buy the Natural Light 24W Solar Attic Fan.

#3: iLiving Smart Exhaust Fan (Best Small Solar Attic Fan)

Our number one best solar attic fan was pretty large, and the Natural Light 24W Solar Attic Fan is honestly massive. Not everyone wants a solar attic fan that’s so bulky, and you don’t have to feel out of luck if you’re looking for something on the smaller side of things. The iLiving Smart Exhaust Fan is just perfect for anyone who wants to keep things nice and compact.

The iLiving Smart Exhaust Fan has a frame of 21 x 21 x 10 inches, though there are even smaller options available. It’s surprisingly heavy, but the smaller frame gives you a lot of leeway, and the adjustable solar panel – which has four different positions – makes the iLiving Smart Exhaust Fan one of the most versatile solar-powered attic fans out there.

But don’t let its size fool you. This iLiving solar attic fan boasts a cooling capacity of 2500 square feet, and the fan has 7 different blades which will reduce noise and maximize airflow. Just like our previous solar attic fan, the iLiving Smart Exhaust Fan is IP68 waterproof, and it boasts a brushless motor.

The iLiving Smart Exhaust Fan comes with a smart thermostat, so it’s also a great option for anyone who prefers that convenient, automated lifestyle. Another feature the iLiving Smart Exhaust Fan shares with the Natural Light 24W Solar Attic Fan (this one a little less fortunate) is that our 3rd ranked solar attic fan is compatible with a lot of extra extensions, but they’re not included.

Lastly, the iLiving Smart Exhaust Fan falls into about the same price range as the solar-powered attic fan from Natural Light. But you’re getting a real Mighty Mouse of an attic fan that offers a lot of flexibility. So if that’s what you’re looking for, the iLiving Smart Exhaust Fan is the obvious choice.

#4: Amtrak Solar Attic Fan (Best Low Cost)

You’re over halfway through our list, and you might be worried that it’s impossible to save money and still get a solar attic fan. But rest assured, there doesn’t have to be a price wall on living a greener lifestyle and doing your part. The folks over at Amtrak made sure of that. Not to be confused with the New Jersey transit company, the Amtrak Solar Attic Fan is just about the cheapest solar attic fan out there, and it’s the exception that proves the rule: “You get what you pay for.”

This dirt-cheap solar attic fan has a powerful 40-watt motor that gives it a cooling capacity of 2,250 square feet, and reviewers have praised it for being nice and quiet. The Amtrak Solar Attic Fan has a frame of 27 x 20 x 4 inches, so it’s definitely a little bulky, but it weighs just 10 pounds, which means that lifting and installing it will be easier than many others.

Other than the amazing price tag and the effective cooling, there’s not really much to write home about when it comes to the Amtrak Solar Attic Fan. This affordable solar panel attic fan will ventilate your attic, keeping it nice and cool and free of mold, but there’s really nothing too fancy going on unless you count the whole solar-powered part. Of course, it’s the cheapest option out there and delivers a great performance, so all the bells and whistles would probably be a lot to ask for.

If you want to buy a solar attic fan without paying an arm and a leg, then go ahead and save your hard-earned money by purchasing the Amtrak Solar Attic Fan.

#5: GBGS Solar Attic Fan (Best Green Solar Attic Fan)

Replace Image below with Amazon SiteStripe Image

One of the most common reasons for deciding to look into solar attic fans is the desire to live a greener lifestyle. If that’s what brought you here, why not go all out and buy the greenest solar attic fan on the market? The GBGS Solar Attic Fan is the best friend of the environment, and this fan features a Smooth Air deflector for better air circulation, as well as a completely silent motor and an adjustable solar panel for some flexibility.

With a cooling capacity of 2,000 square feet, the Smooth Air deflector for better air circulation is the weakest choice on our list, but that’s the price you pay for saving the planet. It also features IP68 waterproofing. It comes with a built-in thermostat that will automatically turn the fan on once the temperature rises above 77 degrees Fahrenheit and automatically shut off at 65 degrees, so staying comfortable is as easy as its ever been.

The Smooth Air deflector for better air circulation has a frame of 20 x 20 x 13 inches and weighs a massive 34.55 pounds. Other than its slightly weak cooling capacity, the biggest flaw with the last solar attic fan on our list is that it’s pretty limited in terms of roof compatibility, which means it’s best to double-check beforehand that everything will fit.

Of course, a nice side-benefit to go with the greenest fan out there is that it’s pretty cheap – all things considered. The only fan on our list that’s cheaper is the Amtrak Solar Attic Fan. So if you want an eco-friendly fan that will automatically turn on and off and that won’t cost you your life’s savings, then the only choice for you is the GBGS Solar Attic Fan. Just make sure it’ll fit in your attic window first.

Frequently Asked Questions

Not everyone is certified in HVAC, and you might still have a lot of questions about solar-powered attic fans – and attic fans in general – that we haven’t answered yet. We wouldn’t be doing our job if we didn’t at least try to answer all of your pressing concerns. We can’t read your mind, but we can address all of the common questions before we send you on your way, and that’s why we’ve added this FAQ section to the end of our article. Keep reading for your HVAC crash course.

Are There Benefits to Solar Attic Fans Other Than Environmentalism?

Absolutely. Even if you aren’t particularly passionate about reducing your carbon footprint or don’t feel that buying a solar-powered fan is the best way for you to do that, there are plenty of reasons to buy a solar-panel-equipped fan for your attic.

First of all, it’s important to have at least some sort of fan in your attic even if it’s not solar-powered, and even if you’re not hanging out there during the hot summer days. Circulation and airflow are important for reducing the chances of mold growth, so it’s best both for your health and for the condition of your belongings to have something cycling the air in and out of your muggy attic.

Plus, a solar-powered fan will be completely removed from the grid. So if you’re really blasting your fan around the clock, throwing a solar panel into the mix is an amazing way to cut back on your electric bill.

Saving the planet is its own reward, but even if it weren’t, there are plenty of reasons to go out and buy a solar attic fan.

How Do I Install My Solar-Powered Attic Fan?

I’m going to be honest. Unless you really know what you’re doing, it’s probably best to just hire a professional on this one. That being said, if you do feel confident you can go it alone and you want to save yourself some cash (you did just buy a new solar-powered fan after all), here’s a quick step-by-step guide of how to install your solar attic fan.
Without detailing anything that I’m quite frankly not qualified to detail, you’re first going to have to pick your attic window and prep it. This may involve carefully measuring and cutting a hole in your ceiling, so remember to leave room for the flashing.

After that, you’ll just have to place the fan in the hole, set the solar panel to the right angle, and you’re done.

As far as tools go, you’ll need a ladder, a power drill, a reciprocal saw, a roofing knife, a pry bar, a wrench, a hammer, caulking gun, chalk, measuring tape, and possibly more. Like I said, if you’re not a certified expert, it’s probably best to just leave it to the professionals.
