There is no actual information on how self sufficient the car actually is. There is only 1 number which states how long the car drives on a sunny day with solar+battery combined.
The car probably needs to charge for days via the solar panels in order to fill up the battery.
there doesn't need to be. It's not. plain and simple. There just isn't enough area on a car's body (remember, most of them won't even be oriented properly most of the time) for panels to generate enough power for self sufficiency. Even if the panels were 100% efficient. This will always be the case for any solar car.
I mean that's just not true unless you're referring to the very narrow scope of powering itself while driving down the highway at 70MPH.
With a sufficiently efficient design and enough solar panels and sun exposure, like can be seen on the Aptera, you can get 30-40 miles of range/day, which is more than sufficient for a daily commute.
