When solar panels are wired in series, the array’s voltage is added together while the current (or amps) stays the same.
When solar panels are wired in parallel, the array’s voltage stays the same while the current (or amps) are added together.
In an ideal world, your camper solar setup will consist of a set of identical solar panels. It's not an ideal world!
So which is best? Our calculator gives you a good idea of the total power output, current, and voltage you might expect from each wiring configuration.
