Basic math. Off course it makes no sense.

Pmax. = 1'000 W/m2 * sin alpha

Size of a tesla 3 is about 4.7m to 1.93m, so apr. 10m2 (incl. windows). So on the aequator, with the sun directly above you, you could get as much as 10kW. Best degree of efficiency on solar panels is nowadays up to 29%, so you can get up to 2.9kW (remember, inkl. covering windows, sun directly above you on the aequator, high noon). If the sun lowers to 30 Degrees, the power is cut in half.

The battery of this Tesla 3 has 50 or 75 kWh, the electric motor 192 kW.

It's just a dribble coming from the solar cells. Far more space is needed.
