SOLAR ATTIC FANS
Give Your Attic a Little Breathing Room.
Cool your attic. Cool your home.
Summer can turn your attic into the hottest room in your house. A solar attic fan uses the sun to push that heat out, so your home feels cooler and your AC can finally take a break.
THINK IT’S HOT OUTSIDE?
160°F
That’s how hot an Arizona attic can get in the summer. A solar attic fan helps move that heat outside.
SOLAR ATTIC FANS
Sunshine In. Heat Out.
A solar attic fan sits on your roof and uses the sun’s energy to pull hot, trapped air out of your attic, so cooler air can flow in. No wiring to your home’s electrical system. No power bill to run it.
1 · SUNLIGHT
The solar panel on top of the fan soaks up Arizona sunshine.
2 · POWER
That energy powers a quiet, efficient fan motor.
3 · VENTILATION
The fan pushes hot attic air outside, all day long.
4 · EVEN AFTER SUNSET
ClimaSense™ models keep cooling into the evening.
REAL PROJECTS FOR ARIZONA HOMEOWNERS
Feel the Difference Overhead.
When your attic overheats, that heat doesn’t stay put. It pushes down into your living space and keeps your AC running long after you’d like it to rest.
An attic that holds the heat
- Heat trapped above your ceilings
- Rooms that feel warmer than they should
- AC working overtime
- Higher summer utility bills
An attic that breathes
- Hot air actively pushed outside
- More balanced comfort through the house
- AC gets a well-earned break
- Less heat stress on your roof
The Benefits of a Solar Attic Fan
Push out trapped heat from your attic by up to 30%
An overheated attic raises indoor temperatures. Venting that heat outside means less of it radiates down through your ceilings.
Reduce strain on your AC
Less heat overhead reduces the strain on your cooling system, which can help lower your summer utility bills.
Help stabilize indoor temperatures
Stop heat at the source, before it settles into the rooms where you live.
Run on solar power – no operating costs
Free energy from the sun, every single day.
Quiet, low-maintenance performance
A brushless, high-performance motor runs near-silently, and Soft Start technology helps it last.
Trust The Data
Heat Reduction
Your attic can exceed 160°F. A solar attic fan removes trapped heat at the source, reducing how much of it transfers into your home.
Energy Impact
Less heat above your home means less work for your AC. This can reduce cooling demand and, in some cases, lower runtime by up to 50%.
Home Protection
Excess heat accelerates wear on your roof, insulation, and HVAC system. Ventilation helps reduce that strain, supporting longer-lasting performance across your home.
ACTIVE VS. PASSIVE VENTILATION
Solar Attic Fans vs. O’Hagin Vents
A solar attic fan actively pushes heat out. O’Hagin vents are passive, low-profile vents that let air move naturally. Here’s how they compare.
Solar Attic Fan
Active, solar-powered ventilation.
HOW IT MOVES AIR
A solar-powered fan actively pulls hot air out of your attic.
POWER
Runs on the sun. No electricity cost.
ON THE HOTTEST DAYS
Moves more heat when the sun is strongest, right when you need it.
AFTER SUNSET
ClimaSense™ models keep venting into the evening.
O’Hagin Vents
Passive, low-profile ventilation.
HOW IT MOVES AIR
Passive vents rely on natural airflow, with no fan.
POWER
Needs no power at all.
ON THE HOTTEST DAYS
Continues to vent naturally.
AFTER SUNSET
Hallways, closets, bathrooms, laundry rooms, and interior spaces.
Frequently Asked Questions
How hot can an attic get?
During the summer, attic temperatures can reach 160°F or more, depending on the home, roof, insulation, ventilation, and weather conditions.
How does a solar attic fan work?
A solar panel captures sunlight and uses that energy to power a ventilation fan. The fan helps move hot air out of the attic.
How much can a solar attic fan lower attic temperatures?
A properly installed solar attic fan can help lower attic temperatures by up to 30%, depending on the home’s design and existing ventilation.
Will a solar attic fan make my house cooler?
It can help reduce heat buildup in the attic, which may help improve comfort in the living spaces below. Results vary based on insulation, ventilation, roof design, and other factors.
Can a solar attic fan help my roof?
Improved attic ventilation can help manage excessive heat and moisture, which can support the longevity of roofing materials and other attic components.
Do I need one if I already have attic vents?
Learn more about it! Existing ventilation does not always provide enough airflow. We’ll evaluate your current setup before recommending additional ventilation.
Can you install a solar attic fan on my existing roof?
In many cases, yes. We’ll evaluate your roof type, condition, and existing ventilation to determine the best installation approach.
