Yes, this exactly. Put the same panel on your roof and charge your car at home (which you do anyway.) You won't mar the car's appearance and you'll get more out of it.

What I would love to see is a Tesla that can act as a powerwall and power your house when the grid fails. Some people hack them to do that but it doesn't look simple or without risk.

This already exists, although not for Teslas. It's called V2G (vehicle to grid) and it's already happening in the UK with the Nissan Leaf.

Not only is this a backup for a rare outage but it makes you money by charging when power is cheap and selling back when expensive. Occasionally the price of power goes negative and you are paid to charge.

If you are in the UK and interested in participating in a trial, see https://www.ovoenergy.com/electric-cars/vehicle-to-grid-char...
