Seasonality

Monthly solar production in Bridgewater

Virginia net metering carries excess credits forward for 12 months, so Jun'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: 16.1%. Elevation about 382 m. Compare every town on the city list, or see how roof direction, tilt and shade change the number.

Questions

Questions about solar in Bridgewater

How much electricity does a solar system produce in Bridgewater?
About 1,409 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 11,272 kWh a year. East- or west-facing roofs make less; the calculator applies those factors.
Who is the electric utility in Bridgewater?
EIA's service-territory data lists Dominion Energy and Rappahannock Electric Cooperative and Shenandoah Valley Electric Cooperative and Harrisonburg Electric Commission for Rockingham County. Boundaries run through the locality; your bill shows which one serves you. Dominion's 2025 average residential price was 15.20¢ per kWh.
Is solar worth it in Bridgewater?
For an average Dominion home (1,038 kWh a month), the default assumptions give a 8.8 kW system costing about $24,464 with a break-even around 10.9 years and $37,189 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 1088427.csv typical-year weather dataset for grid cell 1088427, 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.
