Wind Turbine Payback in Levy County, FL
Wind turbine payback in Levy County
No. The turbine wears out before it pays for itself.
At 30 m, the height a home turbine tower usually reaches, the wind in Levy County, FL averages 4.05 m/s (9.1 mph). A 10 kW turbine there would make about 6,831 kWh a year, worth $1,047 at FL's 15.32¢/kWh. Against an installed cost of about $100,000, that is a payback of 96 years, and the turbine is built to last about 20.
What to do in Levy County
A home turbine is not worth buying for savings in Levy County unless your spot is far windier than the county average, 7.8 m/s at the hub against 4.05 m/s here. Per kW, solar panels would make about 1,419 kWh a year here against the turbine's 683, so get a solar quote first.
What would have to change
- Power would have to cost 73¢/kWh, 4.8 times what FL pays now.
- Or the average wind at the hub would have to be 7.8 m/s instead of 4.05. A taller tower or an exposed ridge can add some of that; a rooftop never will.
Against the rest of FL
Levy County is the 2,027th windiest of 3,144 US counties at turbine height; the national middle is 4.79 m/s. The windiest in FL is Brevard County at 5.62 m/s, payback 39 years.
Month by month in Levy County
January is the strongest month here, at 4.58 m/s and about 836 kWh. July is the weakest, 3.24 m/s and 287 kWh, so the best month makes 2.9 times the worst. November to March brings in 54% of the year's output in Levy County.
| Month | Wind at 30 m | Output | Worth |
|---|---|---|---|
| January | 4.58 m/s | 836 kWh | $128 |
| February | 4.47 m/s | 702 kWh | $108 |

What a taller tower would buy
Measured at 10 m the wind in Levy County averages 3.14 m/s; at 50 m it is 4.56 m/s. That gives a shear exponent of 0.232, typical of ordinary open country. Going from 20 m to 50 m takes output from 5,106 to 9,702 kWh a year, 90% more, before counting the extra cost of the taller tower. Why tower height decides it explains the shear behind these numbers.
| Hub height | Average wind | Output | Payback |
|---|---|---|---|
| 20 m | 3.69 m/s | 5,106 kWh | over 100 years |
| 30 m | 4.05 m/s | 6,833 kWh | 96 years |
| 40 m | 4.33 m/s | 8,346 kWh | 78 years |
| 50 m | 4.56 m/s | 9,702 kWh | 67 years |

Sun versus wind in Levy County
Levy County gets 4.86 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,419 kWh a year; one kW of the turbine above makes 683. Kilowatt for kilowatt, panels make 2.1 times as much here as the turbine. Panel output assumes an 80% system performance ratio. Wind or solar runs the same comparison for every county.
How this is worked out
Wind is NASA's Power climate record, the 2001-2025 average at 10 m and 50 m for the county's centre, carried to 30 m with this county's own measured wind shear and spread into hours with a Rayleigh distribution. The turbine is a generic 10 kW, 7 m rotor machine with 10% losses. Cost is $10,000 per kW installed with no tax credit, because the federal one ended in 2025. One county-centre number cannot see your hilltop or your tree line, so treat it as the starting point for a site survey, not a substitute. The full method and its weak spots are in how the numbers are made.
