For reasonable cost you can get 22.5% panels. A Camry is 193 inch x 72 inch or ~9 square meters. However, you don't get to tilt the panels and need to deal with shade, but can add cells to the sides which helps though at lower efficiency. Still ~6 hours of full sun equivalent x 9 * 0.225 ~= 12 kwh for a fairly normal shape.
Tesla Model 3 gets 310 miles on 75kwh so call it 4 miles per kwh that's 40-50 ish miles per day if you can stay in the sun.
Current records for solar panels well over 40%, so a fully solar powered car may actually be possible even if stupid expensive.
PS: Those solar challange cars are getting impressive. http://solarteameindhoven.itility.nl/ is a 4 seater doing 60+mph though far from street legal.
