I have solar as well and my net meter was 1460 kWh, Inflow 1640 kWh. $186 bill. The car used 960 kWh last month by my best guess. I have a separate meter and rate coming for the car. Everything but the meter is installed and I built a timer/contactor to only charge in off peak hours. Next months bill should be lower. I was looking at your user name. Do you have a 66 Mustang?
