Seasonality

Monthly solar production in Palmyra

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: 15.2%. Elevation about 100 m. Compare every town on the city list, or see how roof direction, tilt and shade change the number.

Is solar worth it in Palmyra?
For an average Dominion home (1,038 kWh a month), the default assumptions give a 9.4 kW system costing about $26,132 with a break-even around 11.5 years and $36,142 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?”.
