How much energy does one personal wind mill make every hour with approximitly a constant 15 mile an hr wind sp

Question

personal windmill a windmill powerful enough to power a house

how much would one cost

Answer 1

At 15 mph a 20kw turbine will produce about 4kw, this would be plenty for an average home. That would be 4kw hours per hour, would be 2880 kw a month or about 3 times my average usage. You would probably have no trouble getting all of your power from a 10kw system and likely could get away with something in the 5 to 10 kw range.  Most manufacturers will have a power curve for their turbine, every one is a little different some are more efficient at low speeds and others in heavy winds, but with a 15mph wind you are in a very good position for almost any wind power system.

This is the web page for the power output for a 20kw Jacobs 31-20  www.windturbine.net/20%20Pwr%20Curve.htm (there are also links on that page to price lists etc. for the Jacobs turbines)  

That is the wind turbine that I have and with approximately 12mph winds I produce twice my electric needs and sell power back to the electric company.  This system costs about $50k and most quality setups that would produce all of your power will probably run over $35k

www.bergey.com has info on their 10kw turbine. I have heard that they build a high quality unit.

Answer 2

that's a 10kw,  or 100 amp generator.

i suspect it's bigger than you were thinking of.

one might note that houses vary.

maybe something around 5kw is more normal.

here's the main url for the company.

Answer 3

I've been doing two years of research and pricing for my condo unit and let me just say

Aviator has the right numbers for electric produced and cost.

Answer 4

depends on the design of the turbine...size

5k and up..

do it yourself it least expensive if you like to do the science.

Jackson Brown has a nice set up at his ranch!

Answer 5

it all depends on many things the propeller span, pitch and the rating of the generator .   so w/o that info it is impossible to answer ......

I have heard that for about 15 K one can install a wind mill that will power up a house
