Size a solar array from the energy your van uses in a day, the sun you expect, and the wattage of the panels you can fit.

How it works
Divide daily battery demand by peak sun hours and the fraction of rated solar energy you expect to recover. The panel count rounds up; expected daily production uses that whole-panel count.
Reference: PVWatts solar resource and system loss model.
What to check before you use the result
Use peak sun hours for the season and location where you need the power. Roof shade, a flat mount, temperature, and charging limits can reduce actual output.
