After studying the various fans on the market as well as other attic ventilation options, I opted to purchase this unit, the US Sunlight Corp. 1010TR. I will share with you my conditions before the install, the install, the results and my overall observations.I have about 5,000 sq ft. of attic over my home with a peak of 18 feet above the ceiling. I had 4 stagnant vents with 41 soffit vents. The insulation is blown in style for most areas and bat type for second floor walls and such. For over a month, I took regular readings of temps using an IR type thermal gun in 3 different areas of the attic. All readings indicated at 3:00 with an ambient temp of 102 an attic temp. of 148 on average. 154 upstairs and 142 over the garage area.I purchased 5 of the 1010TR fans with the controllers. The items were packaged very well including extra cardboard, small item boxes taped closed, zip lock bags for written materials and small zip ties.Because I had existing stagnant vents at the roof peak with openings that were the same as the opening required for the 1010TR, I simply removed the tops and using a cutoff saw, cut flush the riser so that I had a flashing base in place with existing shingles still covering it. I ran 120V service to each opening and mounted the controller boxes along with receptacle boxes right next to the opening on a rafter. Using a tar/cement, I put a liberal coating around the hole extending out 6 inches on all sides. The tar/cement was put on in a coating of just over ¼ inch. Following the instructions, I plugged the fan and solar panel into the controller box and added the power cord from the receptacle to the controller as well. I placed the fan over the hole and lifted it to view that the tar/cement had made contact all the way around the opening. I screwed the fan flashing down in 4 places and coated the tops of the screws with the tar/cement. Using a calk gun with the same tar/cement in a tube, I applied a ½ inch bead all the way around the out edge of the flashing.The circuit feeding the fans is a single line so they are all on one circuit. The circuit is switched on one end but I will add a timer to it this fall. More on that later.The fans began operating as soon as they were mounted and the sun gave adequate energy to power them up. The reading on the remote came up right away and gave indications that the fan was running and indeed it was quietly turning. The following day, I used the same IR temp gun to verify that the numbers either matched or at least that I could get a reading that I could compare to the current temps.For the past 2 weeks, the fans have kept the temp at 117 or lower during the same time period of 3:00 in the afternoon. At night, they are down to exactly ambient of 85 and they don't get above 100 until well after 12:00 noon. So far, I am getting amazing results. My AC system has two units and prior to the install, they would run 22 hours a day. I could sit outside and they would run nonstop for hours. At this time, they are running about 17 hours per day and they cycle off all the time. Again, I am having outstanding results from the fans that I have installed.Since I have 5 fans and they will cycle off in the evening, I noticed that they cycle at different times depending on when they were unable to be powered 100 percent of the time on solar. Thus there may be a time that one is on for its 8 minute run while the other one is off. In order to get optimum performance, all fans need to cycle on and then off at the same time so this is the reason for the addition of a timed switch. I will put a timer switch in the circuit that will shut off the power to the units about 8:00 every night for one minute. The controllers will reset and when power is restored, the run times will be about the same for the remainder of the night.The cost of materials to install the fans was 80 dollars. This included the receptacles, wiring, tar/cement and 2 gallons of Gatorade. The expertise level required to install the fans is low but the stamina to withstand being on a hot roof and working on a slope the entire time is quite high. The ability to have a helper is almost paramount as you never want to be alone in an attic or on a roof.Costco had an amazing deal that meant the cost of the fan plus controller was well below full retail by 35 percent.Installation Time in 100 plus temps for one man was 90 minutes per fan with lots of cool down breaks.Effectiveness of the units is 148 to 117 temps from day one.Usefulness of the controller/remote is very high. Temps on controller match within 1 degree of IR temp gun.On 3 occasions I have called US Sunlight Corp. for questions and advice. In the past 20 years, I have yet to encounter this level of professionalism, courtesy and care.Needless to say, I highly recommend dealing with this company and of course their products.

I bought this solar attic fan from Costco and had a professional roofer to install it on my south-side roof. The fan claims to cover 1350 square foot of attic area and it does not. The temperature difference between attic and outdoor at solar noon (when solar panel has the most efficiency) is about 30 degree F. I was expecting less than 10 degree F difference. I have over 10+ soffit vents, so it's not the intake. They need to stop the false claim.Connecting the controller to it proves to be a bad idea since the controller failed easily due to heat. A few people have complained about this and the solution from the company is to unplug the wires and re-plug the wires to do a hard reset. Who would like going to attic every other week to do this kind of thing? It is a big hassle. However, if you don't use the controller, you can't control the fan when there is no sun. Sunlight company needs to make the controller more robust and heat/cold resistible.Mechanic fan with over 100 watts and thermostat can do a better job and is cheaper. I regret my decision to go solar. It is a premature technology for homeowner.

I have 2 of these in my attic. On an average day of 96 degrees outside, my attic temp was 120. Not a really big drop from the 140+ I was seeing before I put them in, but enough to notice my AC not running as much. Next year I will be putting in one more that way I have three spaced out evenly across the roof covering the sun from morning till dusk, since my attic space is one big open area from the east end of the house to the west end of my garage.If you want my opinion, always take the manufacture rated CFM and or area covered, and cut them in half just to be on the safe side. They always do 90% of their testing in lab conditions anyway, also, clean the solar panels at the beginning of the summer and every month until fall to insure they operate at peak performance.
