This is my second week trying to learn about this - and I get most of my education for most things from SD….
It got delivered a few minutes ago. I was surprised to see the box. It showed the newer style with the metal kickstand. I couldn't believe it. i opened it up and sure enough it's the new style. Nothing on the box says Nextgen but it does say "25% high conversion rate".

In series, the current/amps will go by the lowest panel.
In parallel, the voltage will go by the lowest panel.
So, let's say you have a 220w and a 160w panel you want to run together. If the specs of the 160w are 20V/9A and the 220w are 22V/12A:
Series: 20V+22V=42V, but only at 9A.
Parallel: 9A+12A=21A, but only at 20V
Meanwhile, if you had 2x220w panels with the same spec, it would be:
Series: 44V @ 12A
Parallel: 22V @ 24A
This is why it is always better to match up panels so the voltage and current are the same, otherwise you'll take a hit, one way or another.

To the point above, if you are in series you are limited by the panel with the lowest current. If you are running in series and one panel is in a shadow due to a cloud or a tree or something else it will drop the current of the whole system! That is why I like to run in parallel unless I am in full sun.
