A Perfect Day for Net-metering

Last Friday was a great day for solar power, so great that our house and habits had no way to use the 31.6 kWh generated by our west-facing 7.5 kW solar array.  Charging the car at 1 am only used about 1/5th the power we generated.

Even if we'd started the day with our home batteries empty, we still could not have used all the power we generated.

Fortunately, our solar array is grid-tied and can push the extra power we don't use to our neighbors. Thanks to our net-metering agreement with the utility, our neighbors got to use clean solar power for the afternoon, and we banked the power credit for use on laundry day.
