Do you want to keep your home cooler in the summer in an eco-friendly way? A solar attic fan can help reduce the strain on your HVAC system, keep your upstairs cooler and modestly reduce your electric bill, all by harnessing the natural power from the sun. And, in some locations, you can even qualify for a tax credit for your purchase. Our solar attic fan reviews give you some tips and product recommendations to get you going solar.

What Factors Should You Consider?

Before we dive into our solar powered attic fan reviews, we’ll run through a few factors you should think about when choosing the best fan for your home.

How Large is Your Attic?

The size of your attic will determine how much wattage you need in a solar powered fan. Follow these general rules:

  • 20-watt fan — 1,850 square-foot attic
  • 25-watt fan — 2,200 square feet
  • 30-watt fan — 2,500 square feet

What Type of Roof Do You Have?

Not all solar attic fans fit every type of roof. Be sure to read the installation details and customer reviews to see which fans will work best for your roof. Most solar attic vents fall into two categories: gable-mounted or roof-mounted.

Where’s the Best Place to Mount Your Solar Fan?

Ideally, your solar panel should face south (if you live in the Northern Hemisphere) and be in an area where it won’t get shade from trees or nearby buildings during the majority of daylight hours.

Cost Savings Tip: Be sure to check with your local municipality to see if you qualify for tax incentives toward the purchase of a solar powered roof vent.

Best Solar Attic Fan Reviews

We’ve chosen our best solar attic fans based on several factors, including reliability, quality & durability, ease of installation, features, pricing and more.

Natural Light Review

Natural Light Solar Attic Fan#1

View on Amazon

Natural Light wins our top spot as the best solar attic fan. Endorsed by homeowners and builders alike, Natural Light solar fans give you high-quality materials and a 25-year limited warranty to back them up. They include all the hardware needed for installation, and customers report excellent instructions to get the job done within an hour. The Natural Light solar panel is adjustable from flat up to a 45-degree angle, or you can detach it and mount it remotely for best sun exposure. You can also purchase a turret extension and tile roof flashing kit for installations on tile roofs.

Pros

Cons

  • Easy installation if you have home repair skills (less than an hour)
  • High-quality materials
  • Quiet motor
  • 25-year warranty on entire unit
  • On the expensive side
  • Not meant for flat roofs or side wall mounting

Pricing

Remington Solar Review

Remington Solar Powered Attic Fan#2

View on Amazon

The Remington Solar Powered Attic Fan comes in a close second as our pick for the best solar attic fan. Remington Solar is another high-quality manufacturer of solar attic fans, which come with an unbeatable lifetime warranty. There are several wattage choices, and each fan has an adjustable panel and pre-installed humidistat and thermostat. These fans aren’t cheap, however, and installation can be a bit more tricky than our number one pick (but still easier than most).

Pros

Cons

  • High-quality materials
  • Quiet fan motor
  • Humidistat and thermostat pre-installed
  • Lifetime limited warranty
  • Most expensive in our reviews
  • Installation slightly harder than our number one pick

Pricing

Durabuild Review

Durabuild Solar Attic Fan#3

View on Amazon

The Durabuild Roof Mount Solar Powered Attic Fan rounds out our top three picks as the best solar attic fan. The Durabuild is an excellent value for the quality you get. This fan comes with a quiet 24-volt motor, an industrial grade 20-watt solar panel that’s thermostatically controlled (it turns on when your attic temperature reaches 85 degrees and automatically shuts off at 65 degrees). Durabuild only offers a 20-watt solar attic fan, and their warranty doesn’t come close to our top two picks. But Durabuild does give you a good value.

Pros

Cons

  • Easy installation
  • Less expensive
  • High-quality materials
  • Quiet fan motor
  • Only offers a 20-watt fan
  • Can’t program fan’s thermostat
  • Warranty not as good as Natural Light or Remington Solar

Pricing

  • Check on Amazon for 20-watt fan
  • Limited 5-year warranty on motor; 20-year warranty on solar panel

Best Budget Solar Fan: Brightwatts Review

Brightwatts Solar Attic FanView on Amazon

The Brightwatts Solar Gable Attic Fan is for homes with an existing gable opening. This solar attic vent fan comes with everything you need for easy installation at an extremely competitive price. Homeowners with a small attic (less than 1,200 square feet) should find this fan adequate to pull out the hot air. However, we did find several user complaints that the solar panel isn’t powerful enough to generate enough electricity to run the fan at full capacity. And if you have a larger attic, you’ll need to purchase additional fans to get the job done.

Pros

Cons

  • Easy installation
  • Very affordable price
  • Heavy duty galvanized steel solar vent fan
  • Quiet fan motor
  • Decent 10-year warranty
  • Can’t program fan’s thermostat
  • Not as fast and powerful as more expensive models
  • Some customers report having to purchase a second solar panel to make this fan work

I recently got an email from our neighborhood association about the city where we live offering tax incentives so am definitely considering this for our home as it gets very hot here in the summer and our bills are through the roof (no pun intended!)
