There is a simplest way to recharge your car battery with solar panel, connect the solar panel to battery terminals and wait. When the voltages on the meter reach near 14 volts the battery is fully charged. Now disconnect the solar panel to avoid overcharging the battery.

Please consult the battery manufacturer's data for guidance about how many amps the battery can handle, while charging and discharging. Some solar panels are made just for the purpose of maintaining batteries in vehicles that are parked a long time. They don't go over 13.5 or 14 volts and don't ever produce enough current to damage the battery. These you can just hook to your battery and forget.
