Seasonality

Monthly solar production in Tazewell

Virginia net metering carries excess credits forward for 12 months, so May'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: 14.9%. Elevation about 771 m. Compare every town on the city list, or see how roof direction, tilt and shade change the number.

Is solar worth it in Tazewell?
For an average Dominion home (1,038 kWh a month), the default assumptions give a 9.5 kW system costing about $26,410 with a break-even around 11.7 years and $35,235 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 1030396.csv typical-year weather dataset for grid cell 1030396, about 1 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.
