If a car had 1800 W of solar panels and could sit in ideal sun for 4hrs, it would recharge 7.2kWh back into the battery. That would get the typical EV 28 miles of range. We don't live in an ideal world, so it would not work out like that.
Much better to put the solar panels on a roof and charge the car from the grid.
BTW, even if we replaced all fossil fuel passenger vehicles with EV, that would not save the world from petrol. It's used much more extensively in many other areas besides personal transportation. It would be a nice start though.
