How A Solar Attic Fan Works
1. Heat Builds Inside An improperly Vented Attic
The sun beats down on a homes’ roof and heats up the enclosed attic space. Passive vents (soffit or gable) allow some circulation but do not provide the pressure needed to force out the hot air.
2. Solar Attic Fan Provides Air Circulation
The photovoltaic panel of the solar attic fan collects sunlight that powers the fans motor to increase air movement.
3. Air Circulation Moves Hot Air Out Of Attic Space
The increased air circulation provides the pressure needed to force out the hot air from your attic. Attic venting can cool your attic space by up to 40 degrees!
Attic Venting Key Concepts
Attic ventilation is an important aspect of maintaining the structure of your home as well as saving energy. Improper attic venting can lead to moisture buildup that can cause mold growth and also cause wood rot. The key to proper attic ventilation is to create continuous air circulation throughout the attic space while preventing moisture from entering. In an ideal venting system, air should enter the attic from the eaves or soffits and escape outside at the roofs ridge.
Solar Attic Fans Work With Your Existing Passive Vents
If you’ve ever been in your attic, you know just hot the space can get, especially in summer months. The sun beats down on the roof surface and heats up the stagnant air inside the attic. Building codes require homes to have a passive vent system. But, passive ventilation does not provide the pressure needed to force the air through the attic and outside. That’s where a motorized fan comes in. An attic fan placed at the roofs ridge will pull air in from outside, force it to move through the entire attic space and escape through the attic vent.
Solar Attic Fans Operate Using Free Solar Energy
A solar attic fan is a simple way to add a motorized venting system to your home without needing any extra electrical wiring or structural changes. Natural Light Solar Attic Fans are manufactured using high-impact photovoltaic solar panels to power the fan for free all during the day. The units are fully operation right out of the box and install in less than an hour. Natural Light Solar Attic Fans are available in 4 model sizes to accommodate any attic space – 12, 24, 36, or 60 watts. They are also available in 3 mounting types: roof, curb or gable.
5 Reasons To Install Solar-Powered Attic Fans On Your Home
When you think “rooftop solar,” panels usually come to mind. However, there’s another type of solar you might want to consider installing on your roof.
Solar attic fans are small, standalone rooftop ventilation devices powered by the sun. Like other attic fans, they help cool your attic in the summer and address wintertime condensation issues. Yet you might be surprised to learn that solar-powered attic fans actually work better than their conventional, line-driven counterparts.
Let’s take a look at some of the benefits of solar attic fans.
Improve Home Comfort
By improving ventilation and moving hot, stuffy air out of your attic, solar attic fans work to lower your attic temperature by up to 40 degrees Fahrenheit. This helps keep the rooms below your attic — and their occupants — cool. Be aware that conventional electric fans can sometimes pull dangerous fumes and carbon monoxide from basement or ground-level gas appliances up through your home. The gentler air-moving capacity of solar fans keeps your attic pressure at a safe level while still providing effective airflow.
Removing excess attic heat reduces your HVAC load so your air conditioner doesn’t have to run as often. But did you know that running conventional attic fans often consumes more energy than they save? Solar fans use energy from the sun, so you’ll reduce your consumption of fossil fuel and your carbon footprint.
Protect Your Roof
In the summer, excessive heat buildup in an attic can damage asphalt shingles. In cold weather, the attic is a place where moisture often condenses. This can cause all sorts of moisture-related damage, including rot, mold or mildew. If you notice that metal objects left in your attic tend to rust, it’s a good indication you could benefit from installing solar attic fans. Finally, proper attic ventilation helps prevent ice damming along your eaves and the potential damage it can cause.
Many of the above benefits will directly or indirectly save you money. While the energy savings from using a solar attic fan are typically moderate, consider the value of protecting your roof and prolonging the life span of your air-conditioning unit. Also, keep in mind that home and business owners can still receive a 30 percent federal tax credit for renewable energy units — including solar fans — installed through 2019.
Many people dislike fans because of the noise. If you are one of these people, you can breathe easy: Solar fans are whisper-quiet and won’t keep you up at night. In fact, they don’t even run at night!

Solar attic fans are relatively simple to install. Though they require making a roof penetration, so if you’re not absolutely sure of your ability to install proper roof flashing (or if you’re concerned about the risk of working in a rooftop environment) why not give us a call?
