(1) How quiet (or noisy) is this? (2) Are the solar panel and the fan attached together? Can I install my solar panel at the roof top?

My fan had a bit of vibration that caused some noise. I "fixed" it by tying a cord between the fan motor and fan shroud. The fan is now very quiet and I have to stand outside my home just below the fan to know it's running. The solar panel is separate from the fan and the two connect with the power wire. The solar panel must be mounted on a flat surface, not directly on the peak of a pitched roof. The solar panel mounts to the roof with two flat angle iron (aluminum) brackets so it needs to be placed on a flat portion of a pitched roof. Installation instructions are available from the company's website and clearly show the installation requirements. My fan had a bit of vibration that caused some noise.

It is very quiet. When I stand next to my house, I can hear the wind noise through the vent, but not the fan itself. You should install the solar panel on your roof. The panel itself has a short cord, and the fan part has the 30' cord. Both ends have connectors that snap together. And get the matching thermostat. It is cheap.

It is very quiet you have to really listen for it when I am standing under the fan inside the house. When the tv is on we do not need to turn it on high. The panel goes on the roof with a long connection wire from the fan. I bought a inside out thermometer put the out in the middle of the attic keeps it about 10 to 20 degrees higher then out side. I live in AZ temp in attic about 150 to 180 works.

The fan is so quiet an barely here it outside - no noise inside. Solar panel is attached to the fan, we pulled wire thru vent that is close to the roof (from attic) and panel is on the roof,

Consult the manufacturer. The fan and solar panel are matched to provide sufficient power and air flow. I live in Arizona and solar power is not an issue.

It's more like a very small fan. I'd say it is relatively quiet. It's not a rattling sound or anything. I usually use mine at night so it's ready by morning.

I don't think that fan is going to be loud enough. The sole purpose is to use in a camping sleeping mode.treat your tinitius and get s good night sleep

Ventilates roof area up to 1250 sq.ft. Motor is 24 volts solar panel is 12 Watts. Have no specs on CFM. Contact customer service 1-800-459-4409. I guess since we are using the solar rays it varies to much and will not give us a constant cfm rating. More sun the faster it goes, less sun slower it goes. Go for it. You will won't regret it.

I hope you have a solar panel rigjt. Good! Is the battery part of the fan? Parts that work are one solar panel connected. Two battery connected . Three fan (load) connected. Once battery receives charge. The fan will work. The panel may over charge the battery. Be careful. I use a regulator. Worry free! Hope this helps.

The fan is connected directly to the solar panel with no battery. But for me, it's good. I see no point in ventilating an area when the sun isn't heating up the place.

It's not terribly quiet. It's a bit louder than most computers. It's about the same as my work computer while at 100% usage, which has 5 large fans in it. (most home computers only have 2 medium fans) But since it's a constant drone it isn't really disturbing. The light would disturb you more, which is why we only run ours in the daytime, and to allow the plants to have a night cycle.

Our home is 1400 square feet and it's just right. I think the larger unit would be too much. This one could probably go up to 1500. We have 4 of the 1/2 round roof vents and 2 of the ~12x16 dormer vents - that's more than enough to vent the air out the roof. You'll also notice secondary cooling because the attic get's aired-out. The noise isn't bad - of course that's subjective. Anyway, we have no central air and when it cools off outside at night, the fan cools the whole house very quickly. During moderate days, it keeps a freshing breeze throughout.

It's relatively quiet for a fan. Anytime you have fan blades moving air, you have a hum, of course, just from the friction with the air, but there is little to no motor sound. I find it quite steady and quiet.

I have only had mine installed for a week. It's installed in the front of my 2011 Chevy 3500 HD. I haven't ran the battery down with it because I leave the engine running if it's on. I highly recommend doing that if your gonna use it because as I understand it, it will drain one fairly quickly. I can't tell if the fans are on all the time. Honestly I haven't checked. That said it's quiet. Real quiet. I had a small inverter that plugged into the cig lighter that was much louder and annoying than this one by far. I bought it to charge cordless batteries for my drill. They require pure sine wave stuff because the others will fry your batteries. I also use it now for several other things like laptop, tablet and even a knife sharpener. So far very happy with it.

I wouldnt call it a 'quiet' fan. But neither is it loud. I would put it right in the middle. We can leave it on and not hear it in the bedroom attached to the bathroom if the door is closed, just a low hum, but easy to sleep through. I did notice that it got a little bit louder after a few months of installing it, but I may just need to clean it a little.

No detectable noise and no fan that I saw. However, there are vents along the side so I'm guessing there is some kind of ventilation system to keep it cool. Whatever or however it does that, noise is not a factor.

The solar panel is on top. The only one I found with the panel integeral to the unit.I have it installed on the West wall about 10 feet up. This is a two-story brick home with a big tree in front, overlapping this aide.I'd estimate that it only see's direct sun for ~3 hrs per sunny day.It worked immediatly. I've been showing my neoghbor, and he bought two for the West wall of his house.NO complaints.... Well made...You'll be very plesased !

If the fan to which you refer is the convection oven fan, the answer is no, it is not noisy. The unit appears to be well insulated from sound.

I agree with the previous answer, the more direct sunlight (solar power) the faster the fan will rotate. I presume there is a maximum rotation speed also regardless of the power applied/supplied by the solar panel. It is a nice unit, quiet and keeps my attic cooler.

I would recommend against it due to the noise level of the fans. It would fit however and it would move s lot of air. Have you considered putting wind turbine in your garage roof?
