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...

Bpounds, big panels from 180W and up are twice cheaper per watt than 100W panels and are very common today. 280W are often same size as 220W, 300W is slightly bigger. Solar Blvd is a good source.
Big panels are 24V nominal, this means you need to use MPPT controller, more expensive than PWM, but in the end $/watt cost of 600W system will be the less than 200W.
For sustainable living on solar you want at least 300W. Having more wattage won't hurt, because in rain and low overcast solar output drops several times.
