Natural Light SAF36B-FL Performance Test Feedback
The installation instructions were as straightforward as they get, so there was no trouble with the setup at all. It took about an hour to have the whole thing ready, including cutting the hole to pass the fan through. I set it up in mid-July, so the temperature was more than alright. The only downside is that when there’s no sun, it won’t run. It’s not a hybrid model either, so it doesn’t switch between solar and electric. This would have come in handy during cloudy days, but it’s not a significant downside seeing how its assistance isn’t needed as much when direct heat isn’t hitting the roof either. You can’t actually adjust the speed at which it runs, so you have to get a little creative. What we did to make it run a bit slower and circulate the air at a tamer pace was to cover a small part of the solar panel’s surface so that sunlight wouldn’t hit it whole.

2. Iliving Smart Solar Fan ILG8SF301
Check Price at Amazon
Pros:
👍 Covers large spaces
👍 Can run in high heat – up to 130 degrees F
👍 Waterproof motor
👍 Large-size blades
Cons:
👎 Fairly noisy
👎 Remote and temperature control not included
For those who seek a fan that can handle providing ventilation for a large-size space, this product is the go-to considering that it is rated to cover areas of up to 2,500 square feet without much hassle, providing a hard-to-top
airflow capacity of up to 1,750 cubic feet per minute.
Smart Thermostat Integrated
Likely the standout feature of this product is the thermostat control that ranges from 65 to 130 degrees Fahrenheit since it guarantees increased control over the unit’s operation. You can disable this feature whenever you want to if you prefer to have the fan turn on whenever sunlight hits it rather than at specific temperature thresholds.
Notable Highlights
- Motor – It features a brushless motor that makes a minimal amount of noise when it runs
- Waterproof – The motor is IP68 rated, so there’s no need to worry that it might suffer any damage if the area you live in is plagued by harsh weather conditions
- Adjustable – Set it up as you like since it can be angled at 0°, 15°, 30°, or 45°
- Panel – The polycrystalline maintains its quality over the years
Needless to say, this product doesn’t fail in the warranty department either. Since it is covered against defects for 15 years from the moment of purchase, you can rest assured knowing that potential issues that arise will be handled by the manufacturer free of charge.

3. QuietCool 40-Watt Solar Powered Roof Mount Fan
Pros:
👍 Since it comes with an AC/DC inverter, the fan can run 24/7 as opposed to only during the day when it receives sunlight
👍 Fully adjustable – it rotates 180 degrees and tilts 60 degrees
👍 Fully detailed installation instructions for easy, cost-free DIY setup
👍 Completely maintenance-free motor
Cons:
👎 You have to drill the flushing installation holes yourself
👎 The thermostat is pre-set and you can’t adjust the temperature
While the area coverage of this QuietCool solar fan might be inferior to that of the
Natural Light SAF36B-FL since
it covers 1,900 square feet tops as opposed to the 2,825 square feet rating of our top pick, this isn’t an issue if you weren’t looking for as large area coverage as offered by the Natural Light entry. The QuietCool is a reliable option to remove the hot and stale air from the attic as long as you use it in an appropriately sized space, so if you seek efficiency and good results, give it a go.
This 40-watt model grants a peak 791 CFM airflow, which is why it works for smaller spaces of up to 1,900 square feet in the first place. It’s a plug-and-play product, so there’s no wiring or complicated setup to worry your mind with. What we do warn you is that you have to drill the holes for the flush mounting as these aren’t pre-drilled.
You can adjust it as you prefer since it tilts 60 degrees and rotates 180 degrees. So there are no limitations from this point of view. There are limitations when it comes to temperature settings since the thermostat is pre-set, not allowing you to make any changes. To be specific, it’s set to turn off automatically at 77 degrees Fahrenheit and start running once more at 88 degrees Fahrenheit.
What we like most, however, is the fact that it can run 24/7, not only when it’s sunny outside. This is thanks to the AC/DC inverter that ensures the motor won’t stop working even after the sun sets down. With this eco-friendly solution to keep your attic and home cool, expect to pay 30% less on A/C-related costs. Lastly, we mention that the manufacturer covers the product against defects for 15 years. This hefty quality guarantee should be more than enough to convince you of the product’s reliability.

Check Price at Amazon
Pros:
👍 Easy to install
👍 High airflow – 1,750 CFM
👍 Covers up to 2,625 sq. ft.
👍 Long 10-year warranty
Cons:
👎 Shuts off completely when the sun goes down
👎 Loud operation
Considering that it is rated to provide an
airflow capacity of up to 1,750 CFM and that it is suited for spaces of up to 2,625 square feet, you can count on this fan for larger-size areas, unlike its lower-rated counterparts. Thus, aside from the attic, you can benefit from the superior air circulation it provides for areas like the garage, barn, shed, greenhouse, or anywhere else you want. The best alternative for this model is our runner-up, the
Iliving Smart Solar Fan ILG8SF301. Since it is IP68 rated, it withstands water and dust so that it won’t damage under harsh environmental conditions, ensuring that this is an investment bound to last for a long time.
Another option for ventilation in the garage is to acquire a garage ceiling fan that is specifically designed for installation and use in this space, better catering to the occasion to ensure proper air circulation.
Important Aspects Worth Considering
- Operation – The 24-volt motor that sits at the heart of this fan is powered by the 20-watt solar panel which in turn is thermostatically controlled
- Automatic – When the temperature reaches 77 degrees Fahrenheit, the fan automatically turns on. When the temperature drops below 65 degrees Fahrenheit, it turns off. All of this is possible thanks to the thermostat that the unit is fitted with
- Air deflector - It helps increase exhaust performance, adding to the fan’s long-run operational reliability
- To get the best sun exposure, you can adjust it horizontally up to 90 degrees and vertically at 4 angles, namely 0°, 15°, 30°, and 45°.
- Since it is fitted with a whisper-quiet motor, you can count on it not presenting a nuisance in case you turn the attic into a usable living space.
Easy Installation and Long-Lasting Durability
You can set it up by yourself since it comes with a mounting and installation guide that explains in detail how the procedure should go. What impressed us most, however, is the rated durability of this product. The brushless DC motor is expected to last 10 years, the metal casing 20 years, and the solar panel approximately 25 years. Thus, if you acquire this product you are likely making a long-term investment on which you can count for ventilation.

Check Price at Amazon
Pros:
👍 Runs even in harsh temperature conditions
👍 Affordable purchase
👍 Easy setup
👍 Generous backing
Cons:
👎 Smaller area coverage than opponents
👎 Motor is a bit loud
Better Than Thermostat-Regulated Models
Whenever there is direct sunlight, this Air Vent fan starts running to circulate the air in the attic and create proper conditions comfort-wise in it, making it habitable (this would have been out of the question otherwise) and helping reduce cooling costs during hot days for the whole house since the upper area doesn’t transmit as much heat.
As soon as there is no more direct sunlight reaching the panel, it turns off automatically. This is an advantage as opposed to thermostat-regulated electric power fans that only turn on when the attic overheats since the Air Vent guarantees this occurrence is out of the question from the get-go by running whenever there’s sunlight.
Hard-to-Top Performance
- You can count on it to ventilate the area properly as long as it doesn’t exceed 1,200 square feet in size. If you seek heftier coverage, the Broan 345SOWW is what you should check out instead since it’s suited for areas of up to 3,200 square feet.
- What makes it efficient for an area this large is the 800 CFM airflow capacity it boasts that is rarely seen in attic fans.
- It boasts a two-part construction that comprises the solar panel which collects and supplies the power from the sun to the 24V DC motor of the unit.
Notable General Details
This fan features 3 blades and has a 14.5-inch diameter opening, the whole galvanized steel dome that encapsulates the fan measuring 25 inches in diameter. When you set it up, it’s best to make sure that you place it facing the west or south for optimal sun exposure, and that you provide it with 404 square feet of net free intake air. If manufacturing issues arise within the first 5 years as of making the purchase, the company handles repairs free of charge.

Here’s What You Need To Know About the Solar Tax
In 2015, Congress has renewed the popular solar tax credit which allowed more homeowners to benefit from solar power. When you install a solar power system,
the federal government rewards you with a tax credit for investing in solar energy. Thus, the money will be deducted from the amount of federal tax you owe each year just by having solar power.
- Credit steps down – It’s important to understand that the value of the credit will go down as the years’ pass. In 2022, it is predicted that you will receive no credit if you don’t use it for commercial projects.
- Easy to claim –There are numerous expenses that you can claim. Some of them are solar equipment, freight shipping costs, solar consulting fees, professional installer fees, electrician fees, engineer fees, and tools bought or rented. It’s important to understand that the cost will vary depending on the approach you take when it comes to installation.
- There’s no middle man – Unlike electricity, you will be in charge of the system as you own everything. Therefore, you will have full control of how much the appliances can be powered with and when to turn them on or off. You don’t have to worry whether it will function at nighttime or in cloudy weather as the solar panels are innovatively designed to ensure maximum efficiency.
- Money-saving – The bill states that if the motor doesn’t have a large capacity, you won’t have to pay tax. In other words, if your house runs on solar power, you will save a lot of money as you won’t have to pay the same taxes someone with unsustainable electricity does.
Solar Attic Fan vs Electric
There’s no hiding that a hot and humid attic is detrimental to your home. Some of the issues you will inevitably face if you don’t solve the issue regarding the conditions in the attic include
high electricity bills, a shorter lifespan for the shingles, and mold/mildew. Back in the day, electric fans were the only viable solution to tame the high temperatures in the attic and solve some of the moisture-related problems caused by poor ventilation. Woefully, because of the way these models work, they imply higher running costs since the electric bills skyrocket.
On the other hand, we now have solar-powered fans that do the job just as fine if not better in some cases, depending on the model at hand. The extra perk you benefit from with these more Eco-friendly products is that there are no running costs involved whatsoever seeing how they draw their power from the sun.
Take a look at each aspect to decide which type best suits your needs:

Because these fans rely on solar power, they ventilate the space for which you install them without adding a cent to the electricity bills. Solar power is more Eco-friendly, cost-effective, and overall better option for both the consumer and the environment. Add to these perks the fact that you will be exempt from certain taxes, and you can see why more and more people opt for solar-powered products. Here, we reviewed and ranked the best fans at the moment to help you figure out what model best suits your situation, providing sufficient coverage to handle ventilation in your attic. Before we reach the inevitable end, we want to go over a few of the standout products once more to help you make up your mind.
Best Solar Attic Fan for Sale: Natural Light SAF36B-FL
This Natural Light model comes with all of the installation hardware needed and it’s fairly easy to set up so you don’t have to call a professional to help you with the process. What we like is that it comprises several standout features, including the fire safety switch that automatically turns the fan off when power surges are detected to prevent fire hazards. Moreover, the product is fitted with a DC motor that maintains quality over the years, ensuring that your money is spent as wisely as possible if you acquire it.
Editor’s Choice: ESM Products 30w Solar Fan
Fairly priced considering the stats it flaunts which makes it vastly superior to its competitors, this ESM Products model was bound to catch our eye. It turns on automatically when the temperature reaches 80 degrees Fahrenheit to make sure that the attic won’t ever overheat again. Since it can cover spaces of up to 2,800 square feet, you can use it for ventilation in plenty of other areas, including warehouses, garages, barns, sheds, and more. Add to these perks the 25-year warranty for the housing and 5 years for the motor, and it’s clear as day why we favor it.
Best Solar Attic Fan for Shed: Solar RoofBlaster
Your primary option if you have a utility shed greenhouse, but just as appropriate for attics and garages, the RoofBlaster is a must-have as it provides up to 50,000 hours of operation, which makes it a smart investment from the get-go. If you run it 9 hours per day, this means that it will serve you for up to 15 years. Considering the asking price for the system, it’s safe to say this is a bargain. Woefully, it’s not that great in terms of coverage as it can only service areas of up to 100 square feet, but this is more than sufficient for sheds.

At the third of the price most models come at, you can have the Amtrak, which comes with a 50-watt panel and operates daily from the moment sunlight reaches it. Although it comes at a more than reasonable price, it doesn’t sacrifice durability or safety in use. It makes for an appealing option even for those who live in extremely hot areas as it features integrated protection to prevent unwanted incidents.
