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...

I have 3 panels which had pigtails with MC4 connectors. I removed the pigtails and wired direct to the terminals in the junction boxes on the back of the panels. It's easy enough to get to the terminals if I need to remove a panel. Any connector will add a little resistance. The fewer connections the better.
Even better idea. I wasn't sure if those boxes opened easily. Probably voids the warranty, but that's okay.
