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...

Got it up and charging today. This is what I ended up with, 4@ 100W x 12V Mono panels. Still got some anchoring of cables to take care of, and I will do some roof maintenance at the same time. I've got plenty of space for 4 or even 6 more of these if the mood strikes me. But we'll see how these handle our needs, and I think they are going to be plenty.
The panels on the right are wired in series, as are the panels on the left, and the sides are paralleled prior to dropping down.
I went with the EPever 40a Tracer AN MPPT controller. Their newer "N" model with negative chassis/common.
I will move the remote meter inside, but I've got to get some ribbon cable to extend the length. It only came with 2 meters of cable. I need about 25 feet.
Nice sunny (hot) day today.
