Product Description

Solar Attic Fans are easily installed and a great product for proper attic ventilation. Natural Light brand solar attic fans are top rated by builders and are the highest quality built in the USA! The DC motor is powered by the included solar panel with the attic fan motor moving hot air and moisture out of the attic space everyday. Solar panel is adjustable from flat up to 45 degree angle or can be detached and mounted remotely for best sun exposure. Solar Attic Fans mount on 3/12 to 12/12 pitch roofs. (this unit not for flat roofs or side wall mounting). Moves up to 850 cubic feet per minute. Use one attic ventilation fan for every 1200 square feet of attic space. Note: Purchase the optional Solar Attic Fan Thermostat if to be used in areas with cold winter temperatures. See our Amazon Storefront for this optional part.

After quite a bit of research, I felt that the Natural Light Systems Solar Attic Fan offered the best combination of engineering, quality, and value compared to competitors. As for performance, I conducted a simple test that is reported below, but am not equipped to compare other brands under the similar conditions. Unfortunately, I couldn't find unbiased brand comparisons.

The product sold here is a 10 watt panel unit manufactured in Phoenix, Arizona by Natural Light Systems ([...]). The company also makes a 20 watt panel that costs about $75 more that will probably prove more satisfactory over the long run. The only difference between the 10 and 20 watt units is the panel.

BACKGROUND
I have a house with a moderate pitch (I believe about 15 degrees or so), with a black asphalt shingle roof, located in Mountain View, California. When re-roofing the house a few years ago, the contractor recommended installing several small "eyebrow" vents opposite each other along the ridges. They take advantage of the Venturi effect to exhaust hot air. They really weren't sufficient, though. Wind turbine ventilators were too small to retrofit and obtrusive, and over the years I've 1) installed (and removed) a gable fan (noisy and inefficient), and 2) finally re-engineered a large Vornado fan to direct exhause out of a leeward vent. But it was still a bit noisy and used electricity, of course.

Hence, the search for a low-profile solar attic fan, though, I did consider a new passive system from Aura (see [...]). That company also has a solar panel version, though there are some features I don't particularly care for. I installed the solar attic fan on the leeward side of the house, facing due south, in place of an eyebrow vent, in the center of the house.

Having been a heating & air conditioning contractor, I knew the value of attic exhaust fans: a properly sized fan can keep an attic at least 20 degrees cooler than a gravity-ventilated attic. And if your attic is cooler, your house will stay cooler. The problem is that most 120-volt attic exhaust fans are really noisy. The noise from gable-mounted fans isn't too obnoxious, but the noise from roof-mounted fans can drive you up the wall. (The roof membrane acts as a drum and amplifies both the motor vibrations and the 60-cycle hum.) IN CONTRAST, NATURAL LIGHT'S SOLAR OPERATED DC MOTOR IS SO QUIET, YOU HAVE TO GET RIGHT NEXT TO IT TO EVEN HEAR IT!

I'm very impressed with this product. It is well made, it has good installation instructions, it comes with an exceptional warranty, and if you need to talk to the manufacturer for any reason, Natural Light is very responsive.

The optional thermostat is worthwhile: it prevents the fan from running on a sunny (but cold) winter day.

I looked at a few similar units in local big box stores and I was pretty disappointed. Other fans are made of plastic, or cheap thin metal. This fan is very substantial, very strong and durable. The extra weight does have a drawback in that it's a bit more challenging to get the unit on the roof.

Minor tip: I covered the panel with carboard to stop the fan while installing, but afterwards, (duh), I realized that I could have just unhooked the wiring.

I also detached the panel and fan from the base before the install. It makes it a lot easier to sink the screws in the base into the roof. Next time I will disassemble the unit on the ground and then bring it up and install in pieces.

I wasn't able to simply lift the upper shingles. You really have to remove a few to properly install the unit because the holes for the upper screws are too far back, and using enough sealant would be a challenge with the shingles in place. No big deal, but I think the instructions encourage you to think that the installation is easier than it is.

The included sealant would not be my first choice. I ended up using a SikaFlex-like product from Henry.

I can't quantify the improvement once the fan was in place, but I can tell you that it whirs away all the time the sun is shining, definitely moving more air than the passive setup I had before.

The temperature switch might be a good idea for winter conditions. Hard to say because on the West Coast where I live, humidity is only a problem when the sun is not shining.

I'm planning on getting two more for another house.

*update*

The fan is still going strong about a year later, and I have been pleased with how cool the house stayed even on hot days this summer.

Our crawl space is very difficult to move around, so the price of installing wire to power a traditional exhaust fan was prohibitive. So, solar was a practical choice.
Pros: Installation directions were very clear and easy to follow. Worked the moment the sun hit the panel (so keep it covered until fully installed!).
Cons: Not as powerful an exhaust as traditional fans, but does the job.
Hints: Strongly advise getting the thermostat.

Further update August 2013:

...And 2 years after the first one died, the other one (I have 2 units) died as well. At least I knew how to replace the motors and they did give me the motor for free. If you buy these, make sure it has the "new" motors. I am amazed how loud and annoying (not to me, to the entire neighborhood) these things are when they die. Hopefully the new one lasts 20 years or so.

Addendum, September 2010:

One of the two units failed horribly. It was making this awful squealing noise that pervaded the entire neighborhood. It was louder outside than inside so it took me a couple of days to realize it was coming from my house (I am typically not traveling in the neighborhood while the sun is shining except in a car).

The motor bearings had failed. I called BFM and they sent me a new motor - which bore absolutely no relationship to my old one other than it was kind of round. The bracket did not fit and the holes didnt even line up. I asked for more support and BFM ignored me, then told me to call Natural Light systems (the mfr). To be honest I was surprised BFM did not tell me to talk to the MFR in the first place, but once they accepted paternity of the problem, they should try to solve it.

The mfr said that my unit was an early one and the motors they used back then had a high failure rate, so they had switched suppliers, but it was up to me to make it work.

I had to drill out the holes in the bracket to make them wider to fit the old screws. And I had to do it hunched over in a dark dusty attic.
