Re: I've been pointing this out for years.
You are either not driving many miles per week, or you are kidding yourself if you believe that the total output of your PV panels in a week can hope to match the amount of electricity consumed by an electric car in the same week. The average electric car consumes 34kWh per 100 miles. The average home PV installation produces an average (but highly variable) 20kWh per week.
Also (a) how much did the 34kWh storage batteries cost and (b) what is their expected life period?
