Solar Attic Fan 48-watt - Florida Rated by Natural Light

I didn't expect much from solar, as it's usually disappointing power-wise. Not this. I took it out of the box at home just for curiosity's sake and it started pulling a ton of air. It spun nicely in the shade but in the sun, it kicked into high gear. It easily exceeded my expectations. As a matter of fact, I'd tape cardboard over the solar panel as you install it so that you don't accidentally slip a finger into the blades! I believe that these will save me a nice chunk of change on my power bill!Another thing to consider. My old 120v attic fans didn't come on until the attic temp hit 90 degrees, and cut off when the temp fell back to 89. 90 degree air hung around in my attic (surrounding my 3 upstairs bedrooms on all sides) for hours before the electric fans kicked on. Not so with these. As soon as there's enough light in the morning, they fire up and pull in cooler air, and this continues until the sun sets. This means that my upstairs AC unit doesn't have to fight the warm air stagnating until that magical 90 degree mark was hit with the older ones. This also helps save a ton on electric bills simply because the AC doesn't have to work as hard here in the very hot South. These are well made, surprisingly good quality, and powerhouses!

Very happy with this purchase. I purchased it for our 1,100 square foot gambrel roof garage which has an apartment on the top floor. We put two air conditioning units in the apartment a year ago, and the temperature still wouldn’t come down to where it needed to be. I had this fan professionally installed, so I can’t say if it is easy to install, but I can say it works great! Just today it was 85 degrees outside and I have had the air conditioning on in our house. I went to check the temperature in the apartment, and to my surprise it was 77 degrees! Without air conditioning. I had had our air conditioning on in the house to maintain that same temperature. The attic fan isn’t cheap, but it is definitely pulling a lot of hot air out of the roof and making it easier to maintain a cool temperature in the apartment. I’m now thinking of purchasing one for our home. Highly recommend.

The media could not be loaded.      This is a *large* fan. And this is exactly what I wanted. Fortunately I have a large roof, so relatively looking, it does not look too large. Installed preliminarily yesterday evening: very little light and very little fan circulation; was a bit anxious how much more powerful it could be. But today noon it is blasting the hot air out of my attic. The sound level is nearly silent; less than 1% of my previous very loud fan. What a relief!! Heard a very, very low noise while meditating in room below attic fan. I will probably insulate between fan and roof to eliminate that sound, but no big deal. I'd most likely get used to it without doing anything. Note on video: this is not my final set-up; wood pieces will be removed. Since I removed my previous fan, the hole and roof preparations were already there. So very simple installation for me. I am going to see if I can get away with turning off my air conditioner, at least more of the time. A bit pricey, but with a 25-year warranty, this seems like a very wise investment. Will definitely save money disconnecting the old fan. I bought the optional themostat and fire safety switch. Doesn't make much sense to not have them installed too. Probably the thermostat should have been included with the fan, if not both items. Update: I noticed today that if I cast a shadow over even a small part of the solar panel the fan slows way down. It appears that the circuitry within the solar panel needs to have continuous light shining everywhere on the panel. I will need to keep leaves, etc. off of it, and I assume that when there are partial shadows on the panel, like from tree branches, that the fan speed will slow down. Need to check on that.Aug 29, 2016 update: I did not like the looks of the solar panel on top of the fan. I *really* didn't like its looks! So I decided to separate them. Now the fan housing looks "normal" on the roof, as does the solar panel directly on the roof, where it should be. Easy extension of wiring under the roof. The angle and position of the solar panel on the roof works perfectly. Repositioning the fan several times created various noise rattles. So I decided to place 1-inch Ethafoam between the roof and the bottom of the fan housing. Unwanted rattling noise stopped. Fan is virtually silent inside the house. Yes, that great 25-year warranty is voided. But just shows you how much I did not like the combined look! Love how it looks now!! Got pine trees, like me? I tried covering the solar panel with a handful of pine needles, and the fan speed slowed down a lot. But with the way pine needles scatter on my roof and slide down the roof, this probably will never be a problem. So, happy camper now. (Note: old video deleted and replace with new video.
