Aren't solar-cells on the car like multiple magnitudes less power than regular level 2 chargers?
There was a lot of talk about why Tesla wasn't putting solar panels on the cars when the Model S was still new, and I thought the general consensus was it would need crazy amounts of time in direct sunlight to even make any kind of significant impact on the charge.
I mean just look at this announcement. They are talking about 250kW charge rates at peak for SuperCharging V3, and at those charge rates you'd get 75 miles of range in 5 minutes. A solar panel about the size of the car would put out maybe around 250w (give or take a lot, it's been a few years since i looked into what they can put out). Some extremely inaccurate napkin math would put it at less than a mile per hour of charge while in direct sunlight. It's just not worth it (in my opinion) in almost all cases, and probably won't be for a LONG time.
