Unfortunately, me and my car are at work when the sun is shining on my rooftop.

  You could feed power into the grid to offset your charging usage at night. (Perhaps even come out ahead of where you would be charging during the day, if your power utility has lower pricing off-peak.) Alternatively you could add a home battery.

  10 years from now you will have an electric car. An auto battery changing system where the batteries are charged with solar panels and changed automatically when you park your car at night all made by tesla of course. Currently the loss like battery life and power I feel are too high to make economic sense for using a home battery like powerwell charged with solar to top up your car. But swapping the batteries themselves might work.
