AUTOMATICALLY SWITCHES POWER SOURCE… OPERATES AT NIGHT: Most solar fans “claim” to have a 110v inverter to run the fan at night… except YOU have to climb up and MANUALLY switch the fan!
Remington Solar has solved that issue with the 110v Hybrid Adapter. It AUTOMATICALLY detects low power from your panel, while checking the temperature of your attic to determine if it should run on house power! SOLD SEPARATELY!
BUILT-IN HUMIDISTAT / THERMOSTAT: Whether its humid or a dry climate, this fan was made for your home! Its Humidistat and Thermostat allow it to automatically fight Moisture or Heat based on its readings!
BRUSHLESS MOTOR TO EXTEND THE FAN’S LIFE… TEXAS WINDSTORM CERTIFIED: Say goodbye to brush replacements on your outdated attic fan… This Solar Roof Vent features a brushless motor, which turns the motor without wear or friction, extending the life of your fan! This fan is also Texas Windstorm Certified!
30-DAY SATISFACTION GUARANTEE AND 15-YEAR LIMITED WARRANTY: We’re so confident in this Solar Powered Fan for Attics, we’re giving you a 30-day RISK-FREE TRIAL, on top of a 15-year warranty! If you don’t like it, simply send it back and we’ll refund every cent!
Ounce for ounce, pound for pound, you deserve the best. Our "Brushless" DC motor means "we run quiet and forever". And our warranty backs it up. Brushless is more expensive, but worth it. Compare our cost to the cost of ripping your brushed fan off the roof in 5 years and replacing it. (But some of our competitors want to charge you more for "brushed" motors? Hmmmm.) HINT #2: Overall, we're a better fan, and we're less expensive. Why? Well, seeing our competitors at big fancy trade shows and booths stuffed full of salespeople (earning 20% commission on their fan sales) may have a little something to do with it.

“My attic was hitting at least 145 degrees in the summer in Arizona on some days. The fans definitely cool the house. But it made a huge difference in the attic where my furnace is trying to operate.”
“The cheapest way to cool your attic. Period.”
“I put a Remington Solar gable fan on my shipping container on my ranch 7 years ago. It’s still going strong and keeping the contents cool.”
“Keeps the moisture out during winter and heat out in the summer. It’s so quiet I don’t even notice it’s working unless I go up into the attic!”
“I had not even heard of a solar attic fan. The Remington Solar fan works like a charm. Probably dropped the temperature in my attic by 40 degrees. Installation was a breeze and the lifetime warranty will keep it going forever. Awesome.”

FAQs
What Size Attic Is This Builder Series 20-Watt Solar Attic Fan Designed To Ventilate?
The Builder Series 20-Watt Solar Attic Fan is designed to ventilate a 2,000-square-foot attic. It can also ventilate attics slightly larger and smaller than this effectively. However, you may need to choose a solar attic fan of a different size if your attic space differs significantly.
In general, you want a fan that offers 700 CFM of air movement for every 1,000 square feet of attic space. However, you may need a bit more power than this if your roof has an unusually high pitch.
It’s important to choose a fan size that fits the space you have. Use too small of an attic fan, and you won’t get enough cooling. Use too large a fan, and you’ll waste energy, decreasing the ROI on your purchase.
What Makes This Builder Series Fan Unique?
This small solar-powered fan packs a powerful punch. It’s made with high-performance stainless steel and includes everything you need for installation. Plus, it features a built-in thermostat and humidistat. These turn the fan off and on automatically to improve efficiency, helping you save more money throughout its lifespan.
Another unique feature is the fan’s brushless motor. It rotates the fan without the traditional amount of wear or friction. This extends the product’s life and reduces the potential for costly repairs. It’s also Texas Windstorm Certified. So, you can have complete confidence in the engine’s quality.
We also offer free shipping, a 30-day satisfaction guarantee, and a 15-year limited warranty. These benefits make it easy to try our 20-watt solar attic fan with minimal financial risk. If you don’t enjoy the product, you’ll have 30 days to return it at no cost. This combination of power and convenience is what sets Remington Solar products apart.
You can also combine your fan with our 110V inverter (sold separately). It detects when the fan isn’t getting enough free solar energy to run and automatically switches to house power. This simplifies the operating process further, saving you time and helping you get maximum value from your investment.
What Are the Activation Settings for the Built-In Thermostat and Humidistat?
This small solar fan turns on and off automatically thanks to its built-in thermostat and humidistat. These monitor environmental conditions in your attic area, using the information to improve efficiency. The fan will turn on when your attic reaches 80 degrees Fahrenheit or 75% relative humidity. It turns off when the humidity drops below 55% or the attic temperature dips below 65 degrees.
