Seasonality

Monthly solar production in Abingdon

Virginia net metering carries excess credits forward for 12 months, so Jul's surplus offsets Dec's shortfall. Systems are sized to annual usage rather than to the lowest month. How the calculator models net metering; the current rules by utility are on this Virginia incentives page, maintained by the installer behind this site.

Capacity factor: 15.3%. Elevation about 627 m. Compare every town on the city list, or see how roof direction, tilt and shade change the number.

Questions

Questions about solar in Abingdon

How much electricity does a solar system produce in Abingdon?
About 1,344 kWh per year for every kilowatt of panels on a south-facing roof, according to NREL's PVWatts. An 8 kW system would make roughly 10,752 kWh a year. East- or west-facing roofs make less; the calculator applies those factors.
Who is the electric utility in Abingdon?
EIA's service-territory data lists Appalachian Power and Bristol Virginia Utilities for Washington County. Boundaries run through the locality; your bill shows which one serves you. APCo's 2025 average residential price was 17.16¢ per kWh.
Is solar worth it in Abingdon?
For an average APCo home (1,084 kWh a month), the default assumptions give a 9.7 kW system costing about $26,966 with a break-even around 10.1 years and $46,776 net benefit (nominal) over 25 years. Your bill, roof and shade change that; the calculator lets you enter them. The statewide picture is in “Is solar worth it in Virginia?”.
Where does the sun data come from?
NREL PVWatts v8 (8.5.0), using the 1020648.csv typical-year weather dataset for grid cell 1020648, about 2 km from the town center. Inputs: 1 kW DC, fixed roof mount, 180° azimuth, 25° tilt, 14% system losses. Typical-year data doesn't change year to year.
