Will never perform at 100%, so you should oversize the number of panels.

To keep the calculation easier..Say a panel size is 1 m *2m & have output of 400w (under ideal conditions)

If you want a 'fast' charger, output deceases with each car added (ie now a slow charger).

Unlike servos, when with say 20 vehicles refueling, does not slow down when more cars are added to the queue & getting filled.

Maybe put in a sodium iron battery or vanadium radox battery at the solar panel charge station , that stores energy for peak demand when 4 or 5 cars are there at once , then recharges from solar when there is a lull in cars .
