Seasonality

Summer surplus pays for winter.

Virginia net metering carries excess credits forward for 12 months, so Jul's overproduction offsets Dec's shortfall. That's why systems here are sized against annual usage, not the worst month. How the calculator models net metering; the current rules by utility are on Virtue Solar's incentives page.
