Seasonality

Monthly solar production in Norton

Virginia net metering carries excess credits forward for 12 months, so May's surplus offsets Jan'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 742 m. Compare every town on the city list, or see how roof direction, tilt and shade change the number.
