Aptera has this planned but not sure if they ever reach market maturity.
There also was a project car from the Nordics I think. Can't recall the name though.
Main problem is the large amount of energy a car needs vs what kind of surface area you have and efficiency we get.
An ideal (100% effiwncy) solar cell of 5m² would still need 20 hours to charge a 100kWh battery. And we are way off on area an efficiency in reality.
Well but that would be a problem for keeping the car infinitely running with only solar power. But what about just passively charging it while idle? Cars sit idle most of the time.

Yes, Aptera does not have a shipping product, and if they ship the current design it might not have a large market for it. The have been promising delivery for a long time now, so it certainly looks a lot like vapourware.
