    Sell solar energy to the utility when kilowatts are expensive.

    Charge the vehicle using the utility's kilowatts when they're cheap (overnight).

    A Nissan Leaf has a 3.3 kW charger, and a 24 kW battery pack.  So while that may suggest 7.2 kWhs of charging every time, in reality you don't run the leaf down to completely empty.  My typical charging session is when the Leaf is anywhere from half to two thirds drawn down, and my typical charging session (which I don't do every day) is in four hours or less (this is with 30A 240V home charging equipment).

    According to Consumer Reports, a 70 mile Leaf trip would cost $2.44 in electricity at 11 cents a kWh.  So at 34 cents, absolute worst case, that trip would cost $7.32.  Obviously with solar, the cost is going to be a lot less.

    •  Yah, that's part of the plan (0+ / 0-)

      The time when we generate the most is during peak use hours, and we'll charge the Leaf at night, during the cheapest times.  Hopeful it all works out about right.
