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! A $129 value… included FREE! 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 BRUSHLESS MOTOR TO EXTEND THE FAN’S LIFE… TEXAS WINDSTORM CERTIFIED: Say goodbye to brush replacements on your outdated attic fan… This Solar Roof Vent features a brushless motor, which turns the motor without wear or friction, extending the life of your fan!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.

“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 does the 40-watt solar attic fan cover?
This quiet attic fan can cool attics of up to 3,400 square feet. While the exact amount of cooling effect varies based on your installation placement and the air flow in your home, you can expect good results from this solar-powered attic fan without the need for extra ventilation. It’s also easy to install multiple attic fans in combination to ventilate your home even more thoroughly for rapid cooling and drying.
How much airflow does this fan provide?
There are many ways to ventilate an attic, but a fan with solar power is a top choice. The Remington 40-watt solar attic fan relies on a powerful attic roof fan motor that can move dozens of cubic feet per minute (CFM) for rapid cooling. With appropriate attic and gable installation, this fan offers an airflow of over 1,500 CFM. That ensures a full turnover of the air in even the largest attic spaces.
How does the 110V hybrid adapter improve performance?
A solar-powered attic fan with a thermostat won’t add to your electricity bills, but you don’t want it running all the time when it’s not needed, either. This 40-watt fan includes a built-in thermostat so the fan only kicks on when it’s hot. Since humidity is a major issue in most attics, it’s also triggered by a humidistat to keep your home drier. If sun exposure isn’t direct or reliable enough in your area to keep a solar-powered roof fan working all summer long, the 110V hybrid adapter allows you to rely on your home’s power supply instead.
How does the 40-watt model compare to lower-wattage fans?
This gable attic fan is one of the more powerful options from Remington Solar, thanks to the 40-watt motor. It covers a larger attic space and provides a higher CFM than many similar fans on the market, making it the perfect solar-powered attic fan for most homes. Check out our entire selection to find the right solutions for keeping your attic cooler and managing moisture issues that can lead to mold growth.
