Questions and Answers for Active Ventilation 365 CFM White Powder Coated 5-Watt Solar Powered Roof Mounted Exhaust Attic Fan

A:  I cannot give you a specific answer. The fan is the square type commonly used electronics. I have 2 of these installed in Texas where is you can imagine it gets warm. I typically get about 3-5 years of service before I have to replace the fan. The fan operates on 12 Volts D.C. To my knowledge, there is no temperature overload switch. Generally, these type of fans can handle the high temperatures associated with an attic. I am very satisfied with this product, I would buy it again.

A:  While there is a rating, it does not have any thermal overload protection

A:  No switch, connect solar wiring to motor

A:  No switch. Whenever there is enough solar energy to power the fan, it operates. There is no energy storage (i.e. battery), so as long as there is ample sunlight, you will see it run.

A:  There is no switch. When the sun is over the panel the motor will switch itself on. The close the sun is to be directly overhead to the panel, the more power is produced and the quicker the fan motor runs.

A:  No, there is no switch. Fan runs constantly

A:  No switch of any switch of anykind, once sufficient sunlight hits the solar panel the fan starts.. only way to prevent it from running is to cover the panel... Hope this helps

A:  There is no thermostat on this vent

A:  It does not have a thermostat, comes on when the sun is out only. Cloudy or rainy and it doesn't come on.

A:  No, it's just on or off - depending if there is sun or not

A:  The only way I found was to unplug it from the solar panel.

A:  Place something over the solar panels to block the sun light

A:  You would have to cover it. As long as there is enough sun it will stay on.

A:  you can always add a wiring loop to it to switch to different uses when you dont want the fan like a LED over a dark spot like your closet even during daytime. or charging a battery for overnight security light placed elsewhere. whatever.. Ask any of your friends who knows electricity. Those solar guys need to think more about modular functions with their solar products to give them more multi-flexible purposes . You don't need to vent the attic at all times but it helps to do that whenever it is sunny and you dont feel chiilly indoors.. The last thing you need is to have the fan running on a sunless foggy chillly day! right ?

A:  No switch, but you could cover the solar panel; that would shut it down.

A:  There is no on & off switch, to prevent running one can cover the panel, it takes pretty bright sunlight to get the fan spinning, it would be simple enough install a switch though..

A:  You do not want to shut off attic ventilation in the winter. During the winter homes are kept closed up and the humidity generated by cooking, showering etc. builds up in the attic and will condense on the underside of the roof deck. This leads to rotting and/or mold growth. Attics need to breath all year round.

A:  you would have to cover the solar panel with a dark object

A:  This will only run if the sun is directly shining on the solar panel

A:  it runs only if the sun is shining and cuts off when it is cloudy or dark. there is no switch on it and no battery to store energy when it isn't sunny.

A:  Yes, the vent area on the stack is wider and taller than the fan and presumably would allow air to flow easily around it. The solar panel is mounted on top and would not affect air flow. One thing to note: the fan does not have a thermostat so it operates whenever it gets enough sunlight -- summer or winter!

A:  Yes it does have space between panel & fan for passive are exchange, I relocated my solar panel to get more hours of sunshine

A:  As much as any non motorized one of the same size, I would think. It looks like a slotted open hole, and I don’t see what appears to be a door, if that’s what you were wondering.

A:  Yes. Due to natural convection (heat rises) the vent will allow heat to escape. It will however be slightly less efficient than a passive vent with no fan due to the non working fan partially obstructing the vent area.

A:  No, if the unit breaks it will no longer exhaust air from your attic.

A:  If motor is not working. There will be a small amount. of rising hot air through the openings

A:  I bought the 8 inch fan and they come on automatically.

A:  No they do not. They only work in bright direct sunlight.

A:  No, there is no battery. The solar panel powers the motor directly and does not store energy.

A:  No, the solar panel does not store energy.

A:  No. It won't run on a very cloudy day.

A:  No, the fan runs from power directly generated by the solar panel - there is no battery storage.

A:  The louvers are tight. I don’t think they could get through.

A:  The inner vertical louver cylinder of our products have a very small, 1/8 in. (0.125 in.) opening between the louver blades. This will keep out insects, including yellow jackets. This is more effective than an insect screen, because a screen or netting will eventually get clogged, while our inner louver design allows air to move through the vent without resistance.
