Seasonality

Monthly solar production in Middletown

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: 15.1%. Elevation about 205 m. Compare every town on the city list, or see how roof direction, tilt and shade change the number.

Questions

Questions about solar in Middletown

How much electricity does a solar system produce in Middletown?
About 1,327 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 10,616 kWh a year. East- or west-facing roofs make less; the calculator applies those factors.
Who is the electric utility in Middletown?
EIA's service-territory data lists Rappahannock Electric Cooperative and Shenandoah Valley Electric Cooperative for Frederick County. Boundaries run through the locality; your bill shows which one serves you. REC's 2025 average residential price was 15.49¢ per kWh.
Is solar worth it in Middletown?
For an average REC home (1,195 kWh a month), the default assumptions give a 10.8 kW system costing about $30,024 with a break-even around 11.2 years and $43,575 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 1107304.csv typical-year weather dataset for grid cell 1107304, about 3 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.
