Questions & Answers

Does it have the ability to use electricity to run at night

Asked by: Ed
I bought a 24 volt power brick and a double pole double throw switch. When the sun is out I use solar, when it's not I can switch over.

Can wire be extended

Would there be a way to add to the wire length so that I could put the panel in the sun and the fan in a remote location about 30 feet away. Thanks!
Asked by: Glenn
Wire diameter is what limits extension length. If you use a large enough wire diameter, you can extend a long distance. Of course this can become impractical but within limits it is the only solution. Read on if you want to learn something about this. Okay, DC Resistance 101: A wire's electrical resistance scales with wire length directly but scales inversely with wire cross-sectional Area: R = rho * Length / Area where "rho" is electrical resistivity (not resistance - though related) which for, say copper, is the same for both wires in the example below. Since cross-sectional area goes as the square of the radius, doubling the radius will quadruple the area and therefore reduce the resistance by a factor of four. Under this condition, you could use a wire four times longer with no issues whatsoever....read on.... Example: two copper wires, wire 1 with Length L1, cross-sectional Area A1, similar for wire 2 (L2, A2). DC Resistance is given by: R1 = rho*L1/A1 R2 = rho*L2/A2 If I want L2 to be, say 5 times, longer than L1 (original wire, i.e. the 10 ft piece that comes with this kit) AND I want the wire to look exactly the same electrically, then R2 = R1 is the requirement: Solve for A2. Note: L1 and A1 are kit wire length and cross-sectional area, respectively... Set R2 = R1... rho*L1/A1 = rho*L2/A2 and rho divides out... A2 = L2/L1 * A1 Now, if L2 = 5*L1 (our new wire length), then by substitution... A2 = (5*L1)/L1 * A1 and therefore L1 divides out..... A2 = 5 * A1 which tells us that the longer wire L2 = 5*L1 must have 5 times the cross-sectional area but wait there's more... Area = pi*radius^2 where pi = circumference/diameter which, rounded is approx 3.1415926 but I digress .....so... pi*(Radius2)^2= 5 * pi*(Radius1)^2 and pi divides out... (Radius2)^2= 5 * (Radius1)^2 and finally taking square root.... Radius2 = sqrt(5)*Radius1 which tells us the wire radius must increase by the square root of the length scale factor, here being 5. Why do we care? When you connect a power source to a load, a current flows thus delivery energy to the load to "do stuff". As this current flows through the wires that connect the source to load, the wire presents some resistance (technically makes life harder for charges thereby transforming some of their electrical energy into thermal energy which is why wires get warm under load) and this resistance results in a voltage "drop" which is easily calculated if the current and resistance are known. Voltage = Current*Resistance (V=I*R). This means that the voltage impressed upon the load is less than the source voltage by this amount WHICH IS WHY extending wires in a circuit CAN change the circuit function and efficiency. V_src - I*R = V_load. Note the minus sign....THAT'S WHERE THE WORD DROP (in this context) comes from. HOWEVER, if you follow the math above, so long as you scale the wire size accordingly to compensate for added wire length, the source and load have ZERO sense there is a different wire between. NOTE: this is only true for DC (direct current) and low frequency AC (alternating current). Also keep in mind that manufacturers cut down copper cost by using short wire lengths with small gauge wire (length is chosen so their product functions but has very little margin) so this is marginally ok to begin with. So, if you want to extend, then first add at least 20% to the provided wire size BEFORE you scale for length. If you do not, you may incur heating issues - which, by the way, increases wire resistance as well. You will also incur voltage drops that mean you deliver too little voltage to the load and since Solar cells can generate voltage, they cannot push a lot of current directly so if the wire has too much resistance, the panel will be unable to deliver the current to drive the load. I hope this is helpful to a lot of people. Kindest Regards, ThePhysicist

CAN WORK IT WITH BATTERY 24 V OR 12 DC?

Asked by: JC77
Yes, I imagine it will run with a 24v battery but, you'd have to hook the solar panel up to the battery to keep it charged otherwise, it'd cost you to recharge the battery every time it got low!

How do I know if my attic has the minimum required free air flow for this fan? I have a gable vent on each side.

Ranch style house with 1 vent on each end.
Asked by: Hotsummers
The fan must pull air through it's own housing therefore if your gable vents are the same size or larger than the fan housing, you should be just fine. If you only had the one gable vent, then you'd need to check all the other eave vents/other and look for the sum of all opening areas to be equal to or larger than the fan housing opening.

Rated 5 out of 5 by from solar attic fan this product is pretty nice. although when you see the box the fan is not as big as you think. installation is very easy but I suggest you buy some 2x4's to create a simple box frame to mount it on. in cloudy situations it still works, sun is just flies.its total air output is about 1000cfm. the same a large bathroom fan.the solar panel is 10watts and the motor is 17watts. if your a late morning sleeper or 3rd shifter don't install over a bedroom. during the morning sun it really goes and can be heard as a faint whirling noise through the ceiling.

Rated 5 out of 5 by from Solar attic fan I bought this a few years ago. It did not do so well with only one solar panel, So I bought a second. It works very well to air out the attic at my last place. It dropped the temp in the attic from 160 degrees F to 100 and cut 25-40$ off my cooling bill and the mold cleared up. I have moved to a place without and attic and use it in the foundations to dry it out and also move it to my work shed from time to time. It sure beats stringing electric cords or permanant wiring.

Rated 5 out of 5 by from Pays 4 itself!!! I purchased this solar fan 4 years ago and I couldn't be happier! I live in Phoenix Arizona where the temperatures get up to 116 in the summer so, the temp in my attic got up to around 140 degrees, which could easily cause spontaneous combustion if anything flammable is stored in your attic! Needing more storage, I decided to put an inexpensive particle board floor in the attic and install a pull down staircase in the garage ceiling! Once I placed this fan in the front vent, the temperature has dropped to whatever it is outside and now my wife and I have tons of space to sore out items without the fear of burning down the house! My Heat pump is also in the attic and when the A/C guys come to service the unit, they tell me it's the coolest attic they've ever worked in! This fan also lowers your electric bill if you crack open the staircase and let the fan suck the heat out of your garage as well! The entire house gets cooler because of the fan sucking heat from your ceilings and garage! One quick tip. For my convenience I cut one wire and placed a switch where it's easy to turn on and off during the winter!

Rated 5 out of 5 by from Beyond gable, It works Great as a garage ceiling exhaust fan too! In the hottest part of our Texas summer, my interior garage temperature can get up to 95 degrees. Upon returning home and parking a car in the garage, the temperature can easily get to 105 degrees. So, I cut a 14 inch diameter hole in the garage ceiling, then mounted the 15 inch diameter solar gable fan horizontally, so that it sucks hot air out of the garage and empties into the attic space above the garage. Then, I mounted a solar-powered roof-mount exhaust-fan above the garage. Both solar fans work great, and so quiet! If the sun is shining, the fans are turning. The gable fan and solar panel are solid construction. I only wish the wire cable between the fan and solar panel was longer. The cable is only nine feet long. It really needs to be 15 feet long. I mounted the solar panel on my hip-angle roof with only three inches of cable to spare.

Rated 3 out of 5 by from A little loud Unit was easy enough to install, however it produces a fairly loud humming noise and since its above my bedroom, its noticeable and a bit annoying unless I have my windows A/C unit running. It blows a fair amount of air, however it doesn't turn on as early as my other solar fan. It needs a little more light before it starts up.
