Reasons for building your own: You like to tinker, You want a different controller type or capacity, You want a different stand, You want the controller mounted near the batteries. Not because it is cheaper.
The systems are plug and play and you don't need to understand electron behavior.
I dunno...there seems to be a premium for splitting the panel in two. I just paid $125 for a 100W panel and two 5M power cables with MC4 connectors on them and $18 for a 15A controller. The delta I've seen is about $100.

My 20 AMP Renogy MPPT Controller has pretty big lugs. I have not "measured" them but before I bought I asked Renogy and they said #4 would fit. Just by looking I think that is correct if quite snug. I have no plans to ever go larger than #6 so should be fine.
