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.

FAQ
What Size Attic Can The 20-Watt Solar Attic Fan Ventilate?
The best solar attic fan for your home is one that’s properly sized for it. For optimal performance, the solar panel or fan should be placed near the middle of the attic space to ensure balanced airflow and maximum solar energy collection. Oversized fans will produce too much ventilation, possibly sucking air out of your home that you want to stay there. This small solar attic fan can cover up to 1,800 square feet of space. That means that it’s a good fit for most small to medium-sized homes, or larger homes if you want to install more than one to create a more complex cross-ventilation pattern.
Does The Fan Include A Thermostat And Humidistat?
With a thermostat and humidistat already installed and ready to use, this solar fan is easy to install with less effort. There’s no need to worry about matching the right accessories to the fan or encountering any wiring issues. The thermostat is set so the fan automatically turns on when temperatures inside the space rise above 80°F, ensuring that cold-but-sunny days won’t trigger any loss of heat from the home. Since most solar attic fans are installed to manage humidity that can set off mold growth, the humidistat is a must-have feature. It’ll turn the fan on in the winter if there’s a sudden spike of indoor humidity above 55%, which means the fan turns on when needed and is more valuable than fans that never come on during the cooler seasons.
Considering Solar Attic Fan Cost
Even some of the best-rated solar attic fans on the market don’t include thermostats and humidistats guaranteed to work with them. This can easily add $40 or more to the total cost of installation per fan. Consider the total cost of each fan when comparing different models, not just the cost of the basic equipment. You’re also saving money on installation since there’s less work for your contractor to handle while they’re up on the roof or in the hot attic. Additionally, you’ll save money on your utility bill; thanks to free solar energy, these fans have little to no energy consumption from your power source.
Is the Fan Suitable for Tile Roofs?
Yes. Tile roofs are a little thicker than other materials, which can make it tricky to install some solar roof fans. This Remington solar attic fan isn’t designed specifically for tile roofs, but a professional installer can easily adjust it to fit the raised height of the roofing material. It only requires a basic metal or plastic roofing penetration collar to help raise its mounting position above the tiles. The fan will work great with this type of roofing once it’s installed, since it’s Texas Windstorm Certified to prevent damage to the surrounding materials.
How Does The Fan Perform With Ridge Vents?
Most roofs today feature passive vents at the ridge of the roof to release hot air. While they can work in some circumstances, homeowners generally find the effects of passive vents quite underwhelming on their own. Installing a solar attic fan like this one can boost the cooling power without the need to undo or reinstall any existing vents. This 20-watt solar attic fan works best when you have soffit vents installed to help draw fresh air into the attic, but it’ll work nearly as well if all you have is ridge venting. There’s no need to worry about air being drawn in through the ridge vents either. They’ll continue to let hot air escape when necessary, although it’s unlikely to accumulate much once the fan is in place and operational.
