Seasonality

Monthly solar production in Jonesville

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: 15.4%. Elevation about 508 m. Compare every town on the city list, or see how roof direction, tilt and shade change the number.

How much electricity does a solar system produce in Jonesville?
About 1,347 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 10,776 kWh a year. East- or west-facing roofs make less; the calculator applies those factors.
Who is the electric utility in Jonesville?

Is solar worth it in Jonesville?
For an average ODP home (1,238 kWh a month), the default assumptions give a 11.0 kW system costing about $30,580 with a break-even around 11.1 years and $44,886 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?”.
