ELI5—Why do electric cars not have solar panels?

1.58K 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.

The cost/benefit analysis doesn’t hold up. You couldn’t put enough panels on the car to charge it in a reasonable time even in perfect conditions and the cost of adding the panels would raise the total cost of the car. So, could you? Sure. Would you alienate more buyers for virtually no extra value proposition? Absolutely.
