Below is old thinking. You must engineer the solar panels to the size and weight of the vehicle. Lets say Stella cars have a 1000 pound weight. 15kw powers them 300 miles. They charge in 10 hours and can go 40 mph infinitely. They must have a 1.5kw solar panel. Lets just take an old ULTRAVAN. It is 3000 pounds. Put a 3kw solar panel on it and a Leaf drivetrain and you have something that can go 50 to 80 miles depending on speed every 10 hours. Don't forget the panels will power the vehicle in real time. Just do the math and engineering and your have something. Or you can keep converting 2 ton vehicles and say it can't be done. My 4kw electric trike should have a 400watt or bigger solar panel.

Solar panels on EV's are not for propulsion power but for battery charging during the 8 to 16 hour solar day while parked in the sun, not just the 30 minutes the car is in use. This is for those without a dedicated charger at home.

This has been proven time and time again. There is no way it gets even 20 miles per kWh under anything but perfect conditions and slow speeds. And the energy from the panels again is under perfect conditions. It is so light because it has almost no crash protection.
