Read on for more details about these three models, plus the benefits of owning a solar attic fan.
10-Watt Solar Attic Fan
A 10-watt solar attic fan may not be as powerful as other models, but it is certainly worth the investment as a homeowner. This model features 800 CFM (cubic feet per minute) and can efficiently remove heat and moisture from the air. The 10-watt will protect your home’s roof by reducing any premature aging of shingles. A solar attic fan will reduce attic temperatures, which will preserve the life of the room and your roof. Without a solar attic fan, your home’s air conditioning system will have to work even harder. This will cause your bills to increase wildly, especially in the Arizona summers.

How Does A Solar Attic Fan Work?
Solar attic fans work by efficiently reeling in the cold air from the soffits. Then, the fan will push out any hot air that has found its way to the top of the attic, resting just below the fan’s position. Essentially, this is exactly hot air moves naturally. Cold air remains at the bottom, while warm air stays on top. Attic fans will help move the air, adding cooler air circulation within your home or building.
Attic fans will provide a constant and steady air flow throughout your attic and home. Stale warm air is vented out of the attic, giving the area more fresh cool air. This transfer is commonly known as an “air exchange.” While it may seem normal for your attic to be one of the warmest areas of your home, the experts say this room should never be 10-25 degrees above the outside air temperature. A properly ventilated attic can drastically reduce your total energy costs.
Solar Attic Fan Pros
Here are some of the biggest benefits of installing a solar attic fan in your home:
Runs On Solar Energy
It costs less to run a solar powered attic fan because it is powered by the sun. Meaning, you won’t need any electricity from your home or business to power it up. This save on electricity costs and is also great for the environment. It also wastes less energy and is a more attractive option that other motor powered attic fans.
Makes Attic Space Cooler
Another great PRO about solar attics fans is that they cool down your attic space. Cooling down your attic is the best way to keep your home cool too. The more hot air you keep out of the attic – The more hot air you keep out of your home. This will also keep the attic free from dust and dirt. Solar attic fans will keep your home’s ambient temperature low to reduce cooling costs.
Less Expensive Than Full Ventilation Systems
Solar attic fans are also generally less expensive and easier to install than full ventilation systems. They require less time and a less invasive installation process than these other systems do.
