Approximately 4 square feet of free and clear ventilation per fan. If you have a grill with holes that may obstruct roughly 50% of the grill, then you would want 8 sq/ft of that type of soffit vent.

Can I mount it on a tile roof?

Yes, we have detailed instructions on how to do that. You would remove tiles, build a box out of 2×4’s, mount the fan on top of the 2×4’s, then flash around it. Click HERE to see detailed instructions on how to do this.

What if I have Ridge Vents?

That’s great! Remington Solar attic fans work great with ridge vents. Just remember to install your attic fans at least 5 feet away from your ridge. You don’t want the fan to pull air from the ridge area. You want the fan to create an aggressive convection current from inside your attic and move the air up and out through your fan and your ridge vents. (NOTE: Ridge vents alone will move about 1/3rd the air as an active ventilation system. Many roofers are still unfamiliar with solar attic fan technology, and they would rather sell you what they know. Don’t let a roofer tell you that you can’t use solar attic fans with ridge vents. All of our data and research proves that is not true!)

How much savings can I expect from solar attic fans?

That varies only because the conditions and location of every attic different. Insulation or radiant barrier in your attic will create a different condition that an attic that doesn’t. However, based on personal testimonials from many customers, it is quite common to see attic temperatures drop 40 degrees with the proper use of a Remington Solar attic fan. While this directly relates to utility cost savings, it has additional benefits. Cooler attic means more comfort in the living space below. It also preserves your insulation. (Ever notice why the insulation turns to powder over time? It’s the heat.) It also preserves your roof itself. The president of Remington Solar put 2 25-watt fans on his 2,300 sq/ft house, and attic temperatures went from 147+ Fahrenheit in August, to only 9 degrees above ambient temperature consistently. There have been multiple benefits and less than a 2 year payback.

Will they operate on a cloudy day?

The polysilicate amorphous panels are designed to operate with a minimum of 7 watts of sun power. This means that they will turn on a hazy day. On very cloudy or very overcast days, the fan may not turn, but if heat is generated by the sun on those days, your fan will still operate.

Why is Your Solar attic fan better than an electric fan?

Remington Solar fans are “brushless” which means they run nearly forever. Ask any roofer how long electric ventilation fans last. The answer is typically less than 3 years. Then you have to replace them, which means ripping the old one off the roof and replacing it with another one that will last only 3 years. (NOTE: Not all solar attic fans use brushless motors. This is a standard feature on all Remington Solar models

Why do we use solar panels so much?

We like solar because solar gives us flexibility. It means portability as well as cost efficiency. It also means we can create and use clever applications that leverage small motors to do big things. And because we use solar, many of our applications qualify for federal tax rebates.

Isn’t solar expensive?
