You’ll not be surprised to find out from our solar attic fan reviews that, as the name implies, these fans are powered by solar energy. This means that they use a photovoltaic panel that will protrude through the roof and soak up light, this special feature makes the solar fan ventilator the most cost-effective accessory for your roof that will help you eliminate the over-heating problems.

The bottom line is that in this solar attic fans review we are going to help you chose the best roof ventilator fan to generate cool air without taking a toll on your energy bill. This means:

  • Lower monthly costs
  • No risk of power-outage (the attic fan is powered by solar energy)
  • A cleaner conscience knowing you aren’t harming the environment


While there are many solar installations a family can consider installing a fan on their roof for ventilation purposes, after reading our attic fan reviews, you’ll realize that the great thing about solar attic fans is that they offer a lot of benefits while being relatively easy to install. The solar attic ventilator is generally very quiet and will require very little set-up for the attic fan.
And here’s another great thing about solar powered attic fans: they are almost guaranteed to work right when you need them most! While other solar powered tools and appliances might be ineffective when the sun is out, the great thing about a fan is that you are most likely to want the ventilation when the sun is out! When it’s cloudy, you won’t need to use your ventilation anyway!

On top of all this, the best solar roof fan ventilators may also qualify for tax credits, meaning they’ll save you even more money.


Solar attic fan review – Cooling Guide

Like any fan, a solar attic fan also has the job of keeping your home nicely cool. It does this by specifically cooling your attic, circulating air in order to keep it cool, and thereby reducing some of the strain that is otherwise going to be squarely on your HVAC system.

Remember: hot air rises and so a lot of the warmth will rise into your attic. If you can cool that space, this will often mean cooling the entire house.

Using one of the best rated solar attic fans also has the advantage of helping to reduce moisture and prevents mold from forming. Not only will it increase the lifespan of woodwork and fittings in your attic, but it also helps you to prevent health issues that can arise from inhaling mold spores otherwise. Also, in winter, some of the attic fans we reviewed can also prevent the buildup of ice on the roof.

1. Best Solar attic fan with thermostat by Natural Light

Product Review

This is for sure our best solar attic fans, we can say that because of numerous reasons. First: this is a ventilator that looks the like no other attic fan. It has a sleek design that looks neat and tidy on your roof and that won’t draw undue attention to itself. At 36 watts, it is also highly energy efficient and powerful. In fact, this model may even qualify for solar tax credits.

The product comes with a very impressive 25-year warranty, as well as being made from very impressive materials. Installation on the roof is easy with no wiring necessary and there is an included optional thermostat.

Overall Rating: 5/5
  • Sleek design
  • Sturdy materials and good warranty
  • Powerful
  • Easy installation in the attic

2. Amtrak Solar Attic Fan 40 Watt

Product Review

This is another very powerful solar attic cooling system with a powerful motor and a healthy 10-year warranty. The device uses an attractive chrome finish but isn’t quite as well made as the Natural Light product and feels a little more flimsy. The solar panel also sits flush against the roof.

However, in terms of price, this is a great way to get started. And with positive reviews and that good warranty, you should still be able to buy in confidence. At 35watts, it’s also one of the most powerful from our solar attic fan review.

Overall Rating: 4/5
  • Affordable
  • 10 year warranty
  • Powerful enough for Hot Summers
  • Not as good looking
  • Flat against roof

3. Rand Solar Powered Attic powered Fan

Product Review

This is significantly less powerful than the best solar attic fans from our review and definitely won’t be eligible for tax credits. At just 5 watts you’ll be doing a lot less cooling but it’s also pleasingly simple to install and according to the manufacturers it can still cool up to 700 feet of attic space. It is quiet and looks nicely finished and thanks to the lower power, it also costs considerably less than some of the competition.

It’s all self-contained in a single unit and once again, this is a good choice for someone just looking to get into the world of solar heating and cooling.

Overall Rating: 3/5
  • Very affordable
  • Single unit
  • Easy installation
  • Relatively underpowered

4. Durabuilt Solar Attic Fan Ventilator 20-Watt

Product Review

This solar attic fan from Durabuilt is very similar to the last model on our list, suggesting a common manufacturer. However, it is significantly more expensive and for the extra power it provides (20W). As there are more powerful options out there, this isn’t all that compelling. We consider this one of the less impressive models on the market right now and not great value for money, but with a whole lot of similar product on the site, it was worth mentioning for the sake of comparison.

Overall Rating: 2/5
  • Best design
  • Easy installation
  • Low powered
  • Similar design to others
  • Not great value

5. Solar Panel Attic Fan 30 Watt

Product Review

This is a very nice looking solar fan that has a more premium feel. It is adjustable to best get the angle of the sun and will protrude slightly above the attic roof for extra height. It’s also well suited to flat roofs.

The power is relatively good too at 30W. Overall, it’s a very sturdy option and has positive reviews right now. It’s on the more expensive side though and it doesn’t come with the same authority as Natural Light products – nor the same warranty!

Overall Rating: 4/5
  • Amazing design
  • Adjustable
  • Suitable for flat roofs
  • Most powerful
  • Not the cheapest
  • No warranty
