I think this is why Tesla's home battery is going to be such a big deal in the near future. You could buy your own solar panel system and use it to charge your home battery, which would in turn power your electric car. You wouldn't be adding additional stress to the grid and it would probably be less expensive in the long-run. Not to mention that you'd be running on 100% renewable energy.

Anyone ever do the math on charging your car using a solar panel? I'm guessing that unless you have a massive solar panel setup, it would be tough to charge an electric car and get more than 50 miles out of it.

Nissan leaf has 24 KWhr pack, so a 5 KW solar system getting 5 hours of sun could charge it.

However, the cost of having 2 full batteries (ie panel - powerwall - car battery) would be massive in today's world, where batteries are already a huge cost.
