DC HOUSE 32 Watt Solar Attic Fan Solar Powered Roof Exhaust Fan Up to 3000 Sq Ft,2500 CFM Metal Shell Solar Vent Hail and Weather Resistance

I have a shed that gets over 100* in the summer. I've done all I can to keep it cool. The only thing that kind of works is to run the poor little 8K BTU window AC all day and all night. So, after a few $600 electric bills, I'm done with that idea. The walls and ceiling are insulated, but there is not much air flow. This fan is so quiet that you barely hear it running. I need to put my ear up to it to hear it run. And it does a GREAT job of venting out the room. The different mounting options let you mount it pretty much anywhere. Mine is in the roof. Really easy to install. NO WIRES! The one and ONLY issue with it is if you cover any part of the panel, the fan barely runs. I was testing it, and even with the shade of just my hand, the fan speed drops really low. Weird. If you have direct sunlight, this thing pulls a lot of air. Temps are down in the 80*s at the most now!

This product works. It does lower the temperature in the attic by exhausting the hot and humid attic air out. The difference in over all house temperature during hot summer is noticable. Update 3.2.24: One of the fan stopped working on a clear hawaiian sun. I spun it manually thinking that it may help start spinning again with no joy. There is one good thing that i discovered though, the fan blade and the motor unit can be removed while the entire unit is still mounted on the roof. So i proceeded on removing the motor and took to my workshop and i was very diasappointed to have found that the motor is NOT, again is NOT a brushless motor as stated in its product features. It is a conventional brush type motor. In fact, the very reason it stopped working is the commutator has turned black-an indicative of bad contact with the brushes which were wearing out quickly evidently with heavy brush dust all over it. I am able to clean it, and got it to work again. From the look of the brush wear, they look like they are only going to last for about only a year or two max. I feel bad for the folks that bought these solar fans that may not have the ability to do what i just did to get it running again. Replacement of the entire unit is not cheap. I blame Amazon for selling a falsely advertised product by not fully vetting it. AMAZON should revised this solar fan's product features. Brush-type motor not brushless as deceptively writen. I would like to have a full refund on this purchase. If amazon wants them back, they can pay the roofers to have them removed. 7.3.25 update: Both fan now are obviously have gotten very slow. July is when the sun is most straight up in the sky here in Hawaii and the panels are receiving the most sunshine. Fan 1 is squealing real loud that no birds want to hang around the roof any more. Fan 2 has tremendously gotten slower now. Please if your in the market for solar attic fan, look somewhere else. Read all the other unpleasant comments if I'm not convincing enough. I can not over empathize the fact that these are NOT brushless motors (huge difference). Look at the pictures that I had posted. Note the black dust from the brushes.

Still working after one year. Really helps cool the attic.

I am a roofing contractor. I tried this model out on a recent project. The fan is solid. The exterior housing was very study, which is important in the SE with all the hurricanes. Easy to install and operates within minutes of being in the sun. Good value for the price.

This thing works outstanding I'm fortunate that my attic has a Gable vent on each end and one faces the South and that's where I installed this solar ventilating fan and there is enough articulation from the solar panel mount to put it at easily 20° and I have strong winds where I live and it has never once moved.

Works great. Bought 2 for south side of roof. One had bad welds that failed causing vibration. Contractor who replaced roof and installed solar vents replaced for us free of charge on a 12x12 pitch roof. Otherwise would. Have asked seller to help on reinstall of replacement. Sent photos of damaged vent and was replaced promptly.

This Item worked for about 3 months then started making noise now the motor is frozen I am unable to get support from the manufacturer I would serious consider purchasing this Item from someplace else not this brand at all now I have a solar attic fan that just sit there and does absolutely nothing I have reached out to the manufacturer but my request fell on death ears

took about ten minutes for the install as long as you have all the tools with you,its heavy and large but works like a charm,pulled hot air out of the attic immediately and our small attic space and home had an immediate temp difference on the inside,i would venture to guess about 5 degrees but smaller spaces would probably cool down alot more,this is probably one of the better purchases i have made for the house ever.
