what capacity wind turbine should I buy if my monthly consumption is 1000Kwh for my residence?

Question

does wind turbine a better and economic option for solar panels and what are the cost

Answer 1

1 MegaWatthour is an average of 1.388 kW rate day-over-day, but you don't use nearly as much at night as you do during the day, so it would make sense to double that rate (or even triple it). Triple 1.388 is 4.166 kW. I doubt they make one that size, but they probably make a 5 kW generator.

If you really only use 1 MWhr per month, my hat is off to you, my friend -- you are already fairly frugal with your electric use.

As for wind vs. solar... My own personal opinion is to go solar, because I believe wind is too unreliable. That, and I live in an area that has a vast majority of sunny days per year.
You can get solar panels for about $5.00 per watt. For a system the supplies 4 kW, including the batteries, inverter, etc., you are looking at about $20,000, after tax credits and any government energy rebates.

You WILL still need a battery system (battery bank, inverter, power switch), whether you go with solar or wind.

I would do some research (available from the Dept. of Energy doe.gov) to get information on how much actual wind you can expect in your area. They also have info. on sunshine levels by geographic area.

Answer 2

That's One Million Watt Hours or 1.3 kwh per day or 13, 100 watt light bulbs on all day. Your going to need a wind turbine that can generate at least 4 times that amount. So you can store it during the calm. You might want to conserve first.
