Rated 4 out of 5 by krdl46 solar attic power vent
This product is great, not so much for 1800 sq ft as advertised, but install two and combine the solar panels for increased efficiency, and it dropped the temp in my 2100 sq ft attic by 40*f. Well worth the purchase price as the cost is better than other distributors. Delivery was quoted 5-7 days, I received in two!!!

Rated 1 out of 5 by rich worst purchase ever
this item came with no instructions and no way to connect the motor to the panel without drilling a hole in the fan. the fan does not put out any more cfm's than fans half the price.

Product was well made. Did not flow as much air as I expected . Very dependent on un blocked sun light. Would not work well if you had a lot of tall trees near your house. Also has hook up for extra solar panel .I guess that would increase the fan speed. Missed that when reading info. Overall product looks and works like it should. Just does not get the airflow like a wired fan will do. But does not cost anything to run. For now sunlight is free.

Rated 3 out of 5 by Working design & execution lackluster
We needed two fans for our roof, and possibly more for another building so bought a 25-watt fan from Home Depot but another manufacturer, and this Ventamatic 12.6W in order to compare.
In general there was lack of quality in design and assembly of the Ventamatic. First, there were no signs of damage to outer shipping or inner cartons, yet out of the box, when rotating one of the fan blades hit the surrounding cylinder. We moved the outer end of one of the struts or supports so that the cylinder could return to round. This was careless positioning when assembled but it should not have shipped with such an obvious defect. An assembly jig would prevent this defect.
Second, the welded wire cage beneath the dome, to keep out birds and bugs and sparks, was a good 1" short of covering the gap because of the way it rests on the supports. Design problem? Wire cage cut too short? Skimping on materials?
Third, the plate bars intended to hold the solar panel at an angle are ill-designed. The ends are cut at right angles but need to fit into what is a long narrow trapezoid between the horizontal base and the tilted panel. There are many combinations of upper and lower bolt holes simply impossible to use because the corners of the bars force the hole in the bar above the hole in the base. Did anyone even try this? The user will need to either drill new holes into the bars, base or both, or trim the corners of the bars to bevel, or substitute other supports.
Fourth, unfinished sheet metal edges make it unpleasant to work with. The dome itself has a rolled edge but nothing else was rolled or ground after being cut. Presumably the unit is only handled once or twice in its life so I understand the lack of finish but overall impression is of careless design and execution.
We could have returned the unit for the first defect but the other three are inherent. And we had the holes in the roof, the tools and weather to proceed.
the quality of the crystals on the solar panel was a bit better than on the other model.
A caution: we did not understand from the web page that the wiring between the panel and the motor MUST run through a separate hole in the roof. There is no provision to run it up through the unit, even when placing the panel directly on the dome.
In operation the Ventamatic "warbles", is higher pitched and I can hear it three rooms away. The other model is more quiet; I can hear that it is on but it does not draw attention.
In the mornings, for about twenty minutes the fans can cycle on and off as the temperature bounces around, at least that is our hypothesis. Another dollar in thermostat electronics could add a better threshold? In the evenings the fan cuts off due to sundown even though the thermostat is still calling for power and we do not notice the cycling.
p.s. I have tried two computers, three browsers to upload a photo but always times out.

Rated 5 out of 5 by nocost I was surprised at the speed of delivery!
I am completely happy with the ease of install and the thoroughness of instructions.Two hours from start to finish.My attic in the hot New Mexico sun went from 160 degrees to 92 degrees in three hours and has not been above 95 degrees since.My recommendation is if you do not have one get one!
