Solar Attic Fan with 25-year Warranty! by Natural Light

My initial review, couple days after install... I have appox 730 sq ft of attic floor space and 30 deg pitch w asphalt shingles in light grey. House has ridge vent that were poorly installed. House is turn key foreclosure. Contractor installed my fan. House is typical 3 bedroom split-level which gets HOT in the master bedroom. Attic fan location is slight off center, over master bedroom where most sun is anyway. Purchased the 10 watt unit deliberately. Did not want to risk any gasses, ac, CO, etc from being sucked into whole house. Fan temp switch was also purchased and installed by contractor. Fan is SUPREMELY quiet. Dont care bout that personally. Fan seems to be very good quality. 25 year warranty is a plus. Saw similar solar fan at Home D. and it was 5 yr warranty for $80 cheaper. Not worth it in my book. Whole reason for this is to vent the attic of stale xtra hot air due to roofing paper covered, poorly installed ridge vents by house flipper in 2005. And for confort. Splits are notorious for hotter upstairs. But I am a sucker for split-levels. My central air vents are cleaned and tested and runs 100%. Another big plus is no electrician needed, is Plug and Play, literally and of course save a small bit on electrics with the solar power, plus energy tax credits. There seems to be many schools of thought on attic fans, good and bad. All I know is that I should not get a huge fan. I have soffit vents and they are just big enough for a 950 cfm fan is my guess, so 850cfm mx on this 10 watt unit seemed ok. Again, just wanted a whirly bird without having to mount an actual one. Am going to need to seal up whatever cracks and leaks in attic floor and beef up the original 3 inches of insulation before winter in my Mid-Atlantic region. Probably going with Roxul batts. This fan for me, is a passive subtle ventilator with perks and benefits that should be worry free. I am not a Pro, but just think non-overbearing cfm for appropriate roof is all that matters. Will try and update my experiences with this solar fan in the years to come... But I recommend this fan for anyone seeking to take a lil extra 'edge' of a hot attic along with helping with proper venting. Also, that temp switch is a MUST in my area.(UPDATE. Sept. 2022) Still have the fan on the roof. Been thru an 85mph derecho storm couple years ago and numerous other big storms The solar fan held solid. I believe I paid approx $250 in 2015. Now it is almost $500 with the absolute must, temp switch. Over 7 years now and still quiet and running well. It also provides an 'assist' to my central air by keeping the summer heat down in the attic, making the hvac work a little less harder. My utilities stats and bills show that my house is consistently one of the most efficient houses in my area all year round. This fan was made in Arizona. The fan motor was made in Germany I believe. I am still very happy with this solar fan.

I live in a cape cod house that was built in 1948. My upstairs has always been extremely hot, where you can actually put your hand on the ceiling on days like today (temp was in high 80's) and feel a considerable amount of heat coming through the drywall. In addition, there was a considerable amount of humidity. The attic above the ceiling is without access, and has only one rectangular gable vent on one end. Essentially, the attic space has no air flow. I decided to order this solar powered vent with the additional thermostat. I liked the idea of not having to run any extra wires, or pay for the additional electric usage.Cutting a hole in a my roof was a little scary since I didn't have access to my attic, but I started with a small hole to see where I was, and it all worked out. I actually installed this last fall, after the summer season. It survived through hurricane Sandy's winds of 80 mph with no problems, the thing is built extremely well and solid! So with the wave of warm weather, and a record of 90 degrees today, it kicked on for the first time (that I know of). Sure enough, I checked the ceiling in the room upstairs throughout the day, and it probably only warmed to about 20-25% of what it used to when it was 90 degrees and sunny outside. Normally upstairs is unbearable, but not with the fan installed. Amazingly you barely could hear it too. I imagine it does not produce as much flow as an electric fan, but it certainly does the job for my attic space, which isn't very large. If I had a bigger attic, I would simply order the more powerful solar fan.I will update this post as the summer goes on, just in case I'm jumping to conclusions. I'm pretty confident this fan is going to save me a considerable amount of money on my electric bill, and recommend it for anyone with a small to medium attic space.

I am in Dallas, TX and installed it on my roof about 10 days ago. The installation cost was just $75 (done by southern roofing). By 27th May the temperature has already crossed 90 degrees few days so far. I am pleased with its quite operation and simplicity to install. My attic size is about 1300-1400 sqft. Around 5:00 PM at 95 degree outside temperature my attic temperature is only 100 degree, without this fan the attic temperature would have been at 135 degree. The fan blade spins even when not so bright sunny although not at the highest speed. For the best result place it on the west side of your roof. For best performance, I believe 20 watts fan will work even better. I bought the thermostat switch also but probably there is no need for it in summer in Dallas. The attic temperature is always above 80 degree so thermal switch is useless unless temperature falls below 70 degree. My advice will be to save $25 for the thermal switch and instead spend more money for 20 watts fan. In winter from inside of the attic you can just disconnect the cord supplying the power to the motor so it will stop operating then attach it back during the summer so you don't really need the thermal switch.Overall it is doing its job what it was supposed to do. I'll highly recommend this product.You can find some cheaper fan specially electric powered in the market but my roofer said most of the electric fan motor burns out in just few years so I chose this sloar powered which should have longer life as it runs using DC powered motor.I'll probably update this post again in July when temperature crosses 100 degree mark.
