ELI5—Why do electric cars not have solar panels?

1.56K views

It seems like even a small solar panel on the roof of an electric car would make a lot of sense. When you’re sitting at work for 8 hours, your car can just soak up some sun. I’m assuming there is some sort of problem related to cost, rather than efficiency, but I can’t figure it out.

Edit: Thanks for the help. It makes a lot of sense now. I appreciate the in-depth answers too.

Solar panels actually kinda suck is why. The amount of energy they generate is pretty small for how large they have to be. They are OK when you can pave a huge field with them, but on top of a car, they would generate less than a kwh per day, which is like 6 cents worth of electricity.
