I think home solar is great regardless of your transportation method. Those panels are putting power back into the grid specifically when demand is high due to air conditioning. To actually run your car on sunshine, you'd need a battery system at home. But battery charging losses are greater than the local electrical grid. So it's most practical to use the electricity from the panels at the time of generation and nearby. Here in Sacramento, SMUD, the local utility, has a "solar shares" program, where you buy into a solar farm nearby. It costs a little more year round, but it evens out your bills all year. You get credits for "your" solar panel generation, and you get to increase demand for solar, there are no installation costs, and no maintenance. I think utilities are reluctant to give you time-based billing when you have solar in place. They don't want to pay you peak- or ultra-peak-rates for your solar power.
