Not really an accurate statement. The gauge of the wiring limits the amperage.

Mine looks like they used 10 awg wiring (maybe) That's good for 30 amps.
Panels are rated for maximum amperage, 100w panels are usually around 5A.

Let's use an imaginary panel that's rated for 5A and and 10V. (Easy math)

I could run 4 panels in parallel and get 20 amps at 10V, or I could run 4 panels in serial and get 5 amps at 40v.

Here's a decent overview of wire sizing:
