I'm trying to decide between the 20 watt and the 12-watt. Are the units the same size for the roof or is the 12-watt smaller?

12 watt is almost half the size of 20w fan just get 20 watt and save time with bigger fan it will perform better and only 30 bucks more for the most part.

The 12 volt version will draw twice as many amps, requiring a larger wire size. Watts is watts, its a measure of power passed. Voltage x Amperage = watts so to get the same watts when you decrease voltage you end up pulling twice as many amps.

50 Watt might be to hot for a (Assume Closed Hutch). Would probably think about 25 Watt instead.If you have only two bulbs the 50 Watt could be OK, but otherwise go for the 25 Watt.

I have mine in a 12x20 garage. Does a great job. Is the heater blowing out heated air? If not you may want to have a electrician friend take a look.

The 20 watt unit covers a house with up to 1800 sq ft of attic space according to the item description. That means one unit should cover your house. I do not remember the rating on the 10 w, but it should be easy to find it online.

Its a 1500 watt but there is a low option so you dont have to put it on full strength.

Please be aware this is the lowest wattage unit Farm Innovators makes. If I were going to be looking at 3 gal. and -20 I would think about a higher wattage unit but I have no experience with it in such extreme conditions.

On mine with 450watts it is showing about 22% usage, if linear them 1200 should show about @66%. I don't know if linear, personally I'd opt for a larger unit.

If your going to use it close to a plug most of the time, or drilling in steel or heavy use. get the electric. I have both and the 12v. If your going to build a tree stand...... the 20v is great. overhead work, I love the 12v. it's very light with the LED, awesome. Streight up power, go electic, but think about what you will be useing it for the most. good luck

I have 120w panel on my cabin roof but the sun doesn't hit it that hard....... I struggle to keep one charged. But the 100w is on the roof of my other little hunting cabin that is in the sun all day and it rocks the batteries no prob. Just all depends on the sun.

The base of the unit is 20 3/8" by 19 3/8". The template has you cut a 11" by 11" opening in your roof. This is for the bottom opening of the Light/vent. Your shigles cover the rest of the base. Is has worked very well & it lets in an adequate amount of light; especially for the cost. I bought 2 units. I installed one and am keeping the other as a spare.

All heters are the same really. 1500 watts is 5000 BTUs and it doesn't matter much after that. 13x14 worked fine for me but it depends on house insulation, and outside temperature. It was also supplemental, as the centeral heater was holding the rest of the house at 63.

Depends on the wattage. This unit is good for 20amps. It auto switches from 12 to 24 volts so the wattage capacity will change. Remember the E=IXR rule. Voltage=Amp X Watts. Wattage divided by the voltage will give you amperage. 12volt system,,,,, 20a X 12v=240watts of solar panel ,,,,,,,,,,,24volt system,,,,20a X24V=480Watts of solar.

Hello Laurence, In answer to your question, I don't have a 10 in fan to compare the 12 in to, but I have to believe that the12 can move more air. I am pleased with the fan, it is working in my living room that measures 20' by 24'. I wish I would have got the the tower fan, it's bit bigger and it comes with a remote. Oh and I should mention that it is quiet, but still make a but of noise.
