The Builder Series 20-Watt Solar Attic Fan is designed to ventilate a 1,000-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.
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 flat rate 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.
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.
