Here is a good rule of thumb in determining the size of wind turbine that is right for you.
Your electric bill is recorded in kilowatt hours, (KWH). You will need to convert this number to kilowatts (kW) as shown below.
- Look up your electrical usage, if possible, for the last year. Read the bill where it says your usage of KWH this month, or year.
- Now the math: Take your monthly usage and divide by 30 (representing 30 days), then divide again by 24 (representing 24 hours). This equals the kilowatt sized turbine you would need if it ran at 100% capacity.
- Most turbines will run at about 25-60% of capacity (because of varying winds, wind speeds, and location of turbine on property), so multiply your kW number by 3 or 4, to get the turbine that will be potentially most suited for you.
- Your turbine will pay for itself, no matter what size it is, and does not need to be big enough to cover all your electric usage. The examples shown here are to establish system installations that pay for all your electric utility bill, and create income back from the utility as well.
Example:
1. Your monthly KWH is 1,000. 1,000 / 30 / 24 = 1.39 Kilowatts used on average every hour. The Wind Turbine size you'll need to break even on your electrical usage is (1.39 x 4) = 5.6. You'll need (this is only an estimation) a 5kW turbine to break even.
2. Understand that you may get better results with your turbine than demonstrated here. We believe in giving conservative estimates for your rate of return, only to find out that they worked much better than estimated.
3. We offer customized spreadsheets with graphs to show you your specific rate of return, based on inflation, interest rates, and tax rebates. Call 1.800.274.7001 for your free printout today!
