Solar power on electric cars has yet to become a common feature, but Tesla is about to change that — starting with the Cybertruck electric pickup.

We’ve discussed solar roofs on electric vehicles before, most recently with the one on the latest Prius Prime, but the recurring problem is that they rarely generate enough power to be worth it.

For example, we estimated that the solar cells on the Prius Prime’s roof could generate enough power to add about 2 miles of range during the day. And of course, that’s highly dependent on where you are in the world and where you park your car.
