Oh you mean like the Aptera or the Hyundai Ioniq 5? They do have solar panels built in. Prius Prime as well. These aren’t powerful enough to charge the main drive though, not enough surface area and voltage.

But why not put it on a Tesla if it will be so much more efficient than putting the same panels on your roof of your house and charge your Tesla with that?

Because they want to sell you the cheapest car possible for the most money possible, sell you a home charging unit, sell you solar shingles, sell you a new power plant for your home to go with those shingles. They are not in the business of making their cars efficient, only making the cash flow efficient.

		What stops you from slapping a solar panel on the roof if it is the most efficient way to charge an EV?
