Honestly it seems like a no-brainer to me to put a solar panel on the roof of electric cars to increase their action radius, so I figured there’s probably one or more good reasons why they don’t.
Also, I acknowledge that a quick google could answer the question, but with the current state of google I don’t want to read AI bullshit. I want an actual answer, and I bet there will be some engineers eager to explain the issues.
For range it doesn’t add much in most cases. But it also depends on how long between journeys you have. If you’re traveling in a van and you are going to be stationary for a few weeks at a time then it can start to make sense, maybe with an extra fold out.
