We have 2 non-Tesla EVs and an over-sized rooftop solar array. Our solar panels power our house and both of our cars. We use net-metering and pay no monthly electric bills. We net-up in November. In November of 2020, out total electric bill for the entire year of 2020 and late 2019 was $50. I’m satisfied with a $50 annual electric bill. However, there are members of my local EV Club who spend lots of time trying to get their annual electric bill as close to $0 as possible. Their Zoom presentations bore me to log-off early.
