Wind Turbine Payback in Susquehanna County, PA

Wind turbine payback in Susquehanna 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 Susquehanna County, PA averages 3.7 m/s (8.3 mph). A 10 kW turbine there would make about 5,164 kWh a year, worth $1,091 at PA's 21.13¢/kWh. Against an installed cost of about $100,000, that is a payback of 92 years, and the turbine is built to last about 20.

What to do in Susquehanna County

A home turbine is not worth buying for savings in Susquehanna County unless your spot is far windier than the county average, 6.5 m/s at the hub against 3.7 m/s here. Per kW, solar panels would make about 1,072 kWh a year here against the turbine's 516, so get a solar quote first.

What would have to change

Against the rest of PA

Susquehanna County is the 2,288th windiest of 3,144 US counties at turbine height; the national middle is 4.79 m/s. The windiest in PA is Philadelphia County at 4.74 m/s, payback 44 years.

Month by month in Susquehanna County

January is the strongest month here, at 4.55 m/s and about 821 kWh. August is the weakest, 2.84 m/s and 184 kWh, so the best month makes 4.5 times the worst. November to March brings in 62% of the year's output in Susquehanna County.

What a taller tower would buy

Measured at 10 m the wind in Susquehanna County averages 2.31 m/s; at 50 m it is 4.61 m/s. That gives a shear exponent of 0.429, typical of rough, sheltered ground: trees or buildings slow the low wind a lot. Going from 20 m to 50 m takes output from 2,943 to 10,008 kWh a year, 240% more, before counting the extra cost of the taller tower. Why tower height decides it explains the shear behind these numbers.

Sun versus wind in Susquehanna County

Susquehanna County gets 3.67 kWh of sunshine per square metre a day on average. One kW of solar panels here would make roughly 1,072 kWh a year; one kW of the turbine above makes 516. 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.
