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.
The same could be asked with smartphones.
Why don’t smartphones include solar panels on the back side of the phone?
Do you usually use your phone in the sun or leave it exposed to direct sunlight?
We buy solar phone chargers for use in the backyard. They work ok. It would take a long time to fully charge, but it will keep you from going empty.
