Solar powered attic vent fan

Anyone seen or have one of these? Been seeing videos on them and a relative got one as well. Like many others our attic gets hot as frick and we currently have pretty standard soffit vents. Can’t recall off the top of my head but not sure we have any kind of fan system, motorized or otherwise. These seem pretty legit if installed correctly. Anyone have experience with them?

We had these. Put them on the backside roof so they don’t show from the street. My current house has ridge vents which seem to work well.

Coworker is installing some in the winter and I'm waiting to hear his thoughts before I pull the trigger.

I've got some in my new (to me) house and I was up in the attic 2 days ago and noticed it was significantly cooler than the rooms below that had no AC running.

Are the solar powered fans any different than the electric ones, other than the power source?

If you have enough ridge on your roof, and enough soffit vents, I would fully recommend them
If you go with whirlwind bib vents, just know if they get damaged, or have a defect, you will hear it every time they turn
As far as powered attic vents go, I would stay away... when, not if, the motor goes out, you're also replacing shingles along with the massive hole you cut in your decking... considering you cant just replace the motor anymore and you have to replace the whole unit... we'll, i would run away before giving it a second thought

Make sure they're good quality with metal ball bearings for the whirly birds instead of plastic. Plastic melts at high speeds i.e. hurricane. This leads to.the turbine freezing and being ripped off. Electric fan motors will always burn up. Electric motor on a solar unit would probably also.

I replaced the motor on one I had in a previous house.

They work great but aren’t cheap. The ones we install are called attic breeze

All powered attic fans need to be placed in front of a moving asphalt roller.

Installed Remington builders series 40 watt solar attic fan 20 months ago. $300 at Amazon. So far electric bill down 7%. No leaks and attic is as cool as outside temp.

I have been looking for a small solar powered attic vent fan for my shed, but I have not found one yet. I don't have power at it and it gets hot in there.

Do those of you with vent fans also have ridge vents and soffit vents?
Posted on 8/13/26 at 8:07 pm to bluemoons
I had no ridge vents unfortunately and obviously no whirlybirds. I live in the Woodlands and have a two-story house and the solar powered attic vent has actually been a godsend so far

Does your attic have to be sealed off good from your house. I have alot of can lights everywhere throughout the house and ive heard an attic fan can pull conditioned air from the house to the attic

That can indeed happen, particularly with stronger electrically powered attic vents, even under conditions where sufficient soffit vent area is available for “make up” ventilation air. Air, like water, will take the path of least resistance. Attic should be sealed really well from the conditioned area below.
From what I’ve read in the state of GA, since 2012 (?), it’s against code to install electrically powered attic vents in new construction, although solar powered attic vents are allowed.

Would like to see how they work. I moved into a house with a 7-year-old electric vent fan and a few months later the breaker kept tripping. I ended up checking the fan and found a bushing had worn so badly that the motor couldn't spin and blew the breaker. Had the entire thing removed and patched when the shingles were replaced.
