Is that $12000 Canadian? I don't know the exchange rate. Could you state this in U.S. dollars?
How tall are the trees in your area?
Is it an upgraded inverter or a completely different inverter ? Does the inverter have a seperate choke (looks like a large transformer in a seperate housing from the inverter)?
1440 kwh/ month would be for an average windspeed close to 12 mph.
"This windmill needs to be economical and comparable to increasing the KW of the present transformer and paying the extra charges." I don't see the relevence of this statement as the wind turbine cannot lower your peak demand unless you plan on exeeding 20 kw only when it is windy (very impractical)
