How does this differ from the VXSOLDOMWGUPS, dome mounted model? It looks like there's no metal foot plate, but hard to say as picture is cut off. All the specs are the same. Thanks!
Asked by: Chuck
Yes, all of the specs are the same for the units. The only difference is how the solar panel is mounted. You have the VXSOLDOMWGUPS that has the solar panel mounted directly to the dome. The VXSOLARWGUPS has the solar panel mounted away from the unit. This one you can decide where you would like to mount the panel.

how does it turn on and off without a thermostat

Asked by: bob
Hi bob, this unit will operate as long as adequate sunlight is available to the solar panel. If you'd like to control the operation with a thermostat, we have a compatible DC thermostat that can be purchased separately under part number XXSOLARSTAT. You can give our customer service line a call toll-free at 800-433-1626 for more information.

can it be mounted vertically

Asked by: fred
Hi Fred, We do not recommend this unit be mounted vertically, as this could allow rain to enter the attic space.

Cool Attic 1000 CFM Grey Solar Powered Roof Attic Vent with Roof-Mounted Solar Panel is rated 4.4 out of 5 by 8.
Rated 4 out of 5 by from Too Early To Tell I bought this as a replacement for a fan with motor brushes. So a main criteria was to have an easily replaceable, commonly available, standard brushless motor. This met that criteria. It's installed and running so my suggestions are: The motor leads are too darn short. As it is, they connect 1 inch into the skirting. That's a very inconvenient location. Ideally they would go into the attic, but that means puncturing your roof to access the solar panel (since it's not attached). The motor leads need to be at least 2" longer. Its laughable to expect this highly-plasticized cord to last 20-30 years (the life expectancy of a roof). This stuff will degrade to dust in 3 years. It needs to be installed in some sort of conduit. I used a piece of old polyethylene sprinkler pipe (the flexible black stuff). It's fine to kit this cord, the instructions should say "put the cord in conduit or you'll be replacing soon" or something to that effect. Also, I used some Spiral-wrap wire containers on other sections of the cord that are in year-round full sun. Back to the motor leads--the housing needs a grommeted exit port so that the cord doesn't exit under the sharp sheet metal. The instructions should list that you may need wire connectors. While providing adequate cord is commendable, the correct installation will not have much excess. A couple of pairs of M/F connectors would be nice. The big plusses for me are: BRUSHLESS MOTOR. I found this or a very similar motor on several industrial supply sites. I'm not worried about having to find some goofy-sized motor brushes every year. It's a fairly standard configuration. Except for not having a grommeted wire port, it fits right in where the old one came out. Easy doughnuts to install. Lots of wire. Good. If you can trim it and install new connectors. The panel allows for additional connections!!! EXCELLENT! I salvaged the panel from my old fan and added it to this one. Now I have a panel for east exposure and another for SSW. (I live at 43 degrees north). My fan now starts hours earlier than before and doesn't have to try to catch up. Wonderful design. The sheet metal work is surprisingly good. It should last my lifetime in this dry part of the world Last word. This unit is only as good as the motor. The motor is only as good as the bearings. Only time will tell. Ventamatic bets that it's last two years. I'm expecting 10. We'll see.

Rated 4 out of 5 by from Moves a lot of air! I bought this product to ventilate my Palo Alto, CA garage which often gets very hot under summer sun. First the PLUSSES: 1. Fan and solar panel were easy to install on my sloped, composition-shingle roof, 2. Detached solar panel can be mounted up to about 25' away with included wiring, 3. Fan operation is mostly quiet, 4. Fan is highly efficient and air movement is significant when panel is in direct sun and generating maximum current. The MINUSES: 1. Fan motor makes a whistling noise during early morning hours when there is some, but not quite enough, sunlight to turn the rotor, 2. No thermal switch is included (for the price, I think it should be; this would automatically stop the fan from running when temps are cool so that heat is not ventilated away from the house during winter), 3 Screws that are provided for mounting the solar panel are not long enough to fully penetrate roof shingles and grip sub-roofing, 4, No sealant or weather stripping is provided to prevent roof leakage under fan flange or around solar panel wire hole. On the whole, this is a good product and I am considering buying a second one for my attic.

Rated 4 out of 5 by from Easy to install but... The product had no defects and worked once installed. The installation instructions on the HD website and those coming with the unit are different leading to confusion over sealing the unit on the roof. I'm a do-it-yourself person and was initially intimidated by the instructions, but guessed my way around them. Otherwise, the product is good and allows for a ventilation system without running a 110V line into my attic. Fan is VERY quiet and does not need direct sunlight to operate.

Rated 4 out of 5 by from Great idea, average performance. This solar fan is a great idea. On a scale of 1 to 10 I would rate the performance a 5. Solar powered devices rely on an optimum exposure angle to the sun to perform at their best. When pointed directly at the sun I would rate this fan a 7 compared to a 120 volt ac fan rated at a 10. Problem is it can't always be pointed to maximize its performance. So there is a compromise, the advantage for this solar fan is the power is free. Depending on where you live a 120v attic fan may cost you $15-30 or more a month to operate. I pointed the solar panel directly at the sun when it's about 2-3 pm this is shortly before peak temperatures. This angle keeps the fan running strong late in the afternoon when outside and inside temps are at their highest. The fan will run whenever there is light, although barely when the light is indirect or overcast. You may need different screws to attach the mounting brackets to the solar panel frame (they are too small in diameter). Also if you don't have a south facing roof slope with unobstructed solar exposure you will need to make some supports to tilt the panel toward the sun. I used (2) 12" threaded rods with 8-32 threads and a package of 8-32 nuts plus 2 flat 2" metal braces that I bent into a kind of "z" shape. The "z" braces screw to the roof giving a raised contact with the threaded rod which attaches to the solar panel braces and the "z" braces with (2) 8-32 nuts at each end for adjustability.

Rated 5 out of 5 by from Great Peforming Attic Vent Fan It's been about a month since I had the Ventamatic Solar Powered Roof vent fan installed and I can say that I've noticed the difference it has made upstairs. Runs extremely quiet, you don't know that it is operating.

Rated 4 out of 5 by from Works great Minor complaint, it should include an adjustable bracket to set panel at the correct angle for your latitude. Our roof pitch is too low, so I fabricated an adjustable bracket to correct the orientation.
