I need to install a solar-powered garage attic exhaust fan to reduce the heat buildup. I see an ad in the paper by Corad Inc., for this. Has anyone used them? I'd appreciate any recommendations.

Most folks use Solar Guys. I did and I'm quite happy, though I chose an electric fan rather than solar.
Keeps the garage relatively cool and I'm sure it helps the attic. I've had it 10+ years now, not a problem.
Good luck.

If you heat flow in your attic (soffit to the ridge vent) is working like it should, no need for a attic fan.

A solar fan is too weak to move much air, if you are really serious about this get an AC powered fan with a thermostatic switch, this will aloow the fan to run when required. Cost will probably be similar to a solar fan especially if you can use an existing vent cutout.

If your garage faces west only hot air from outside will be pulled inside the garage. Look into a retractable screen door and / or insulation.

We recommend an electric fan for the garage. This gives you full control even if the sun isn't out. For instance if you pull a car into the garage in the evening. That car engine can heat the garage up and our fan will help pull the heat out.

Talk to a Reputable Roofer…. That’s what they do….

Another vote for a 110 AC powered fan, especially if you have a garage larger than a single bay. Too little power with a solar fan.

Solar Guys does these installations everyday and has it down pat. Very good results at affordable prices and available at reasonably short wait times.

The Solar Guys do perfect work at a fair price. Why go elsewhere?

So your house was designed for HVAC by an engineer, they design attic vents to handle this.

But you think lowing the temp a few more that the designed flow is going to make difference?

There have been studies done on this and they found these fans suck the cool air out of the home thru tiny openings in ceiling and walls.

So you spend $$ for more AC.

I think they are a waste of money, google it!

I highly recommend Solar Guys. We have the vents in our garage door, an electric fan in our garage ceiling and the solar attic fan. It makes a huge difference! Their Solar tubes are excellent as well.

You may want to check the fire code on that.

There are several good reasons for not venting into your attic, or creating positive pressure into your garage from outside: venting to the attic creates a fire chimney from the place where your flammable products are stored. If the garage were to burn, you just torched the rest of your house.

Will the insurance pay????

We have a solar exhaust fan installed by Solar Guys. (I have a background in that area, but it was more fun watching them do the work ). The fan is sized sufficiently to pull air through the garage cooling it quite well. It doesn’t chill your beer, but you can work in the garage. We chose garage vents in the doors and painted them to match. The garage screens are fine too. Love the system. It cools after dark too. Technology advanced quickly in the last few years. (Solar powered usually means battery operated.)

Our Lazy Daze RV used solar technology too, so we knew what we were getting. Those Fantastic Fans were amazing .. temp triggered to protect your pets and comfort. Our attic fan is just as good. We were in the attic yesterday in this darn heat. Not bad, but warm.

Whoever said solar is too weak to move much air needs to revisit the technology. Just choose the right size. I always size up if given a choice. Guess I like the power of a whole house fan.

The same thing can be said about the open concept floor plans. Whoosh is the word if you are not careful. Fans definitely moderate temperatures in the attic and garage/ lanae reducing stress and flex on construction materials. Your house will love you more.

I love all these experts. I was in the business for over two decades. First: many sizes of solar attic fans
2-26% Federal Solar tax credit
3-Air Vent makes the only reliable ridge vent. Go to their web site to learn why standard ridge vents seldom work as designed
4-principle of attic ventilation is to bring in the cool air from the soffit vents to displace the hot air in the attic through the fan
5-the best location for a roof fan, be it electric or solar is at the peak of the roof which means blocking the ridge caps to prevent negative air flow.
6-even in the colder months you still need to vent your attic. Electric fans have T-Stats while, unless you live in Arizona, Solar fans run year round.
7-Solar fans use ball bearings and generally have a 20 to 25 year warranty. Check the warranty on electric fans as well as the motor.
Hope this helps.
