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...

Except for some really tiny egg-shape 5-ers, there is no way you don't have enough space for 560W (at least). That would be 2*280W in series. With 40-45A MPPT controller. ~$700 total.
2*100W is a no-brainer, with PWM Grape 40 controller, $280-300 total including extension cable. For parallel wiring you will need a pair of MC4 Y-splitters
