Solar MC4 connectors - needed? Why?
I'm in the early planning stage of doing a solar install on our fiver. I see the MC4 connectors and combiners are commonly used, and I wonder why, and if there is a reason why I could not just solder...

MC4 makes it all plug and play. To pull wire to the controller get a pre-made MC4 extension cable and cut in half. MC4 ends on the panels, cut end on the controller. MC4 cable is always UV resistant.
Combiner-junction box just adds a fail point. MC4 is used on home installations and expected to last 30+ years in all conditions.
Otherwise no, you don't need MC4 if you really want to roll your own.
