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...

The MC4 wire and connectors will far outlast even an exterior rated extension cord. The connections are waterproof and UV resistant. IMO, there is no good reason to use anything but MC4 for solar installation.
FWIW, I like to solder and seal my connections, also. I have a dozen wires under the trailer that are all lead through conduit and boxes to their final termination on the tongue of the trailer. Their terminations at the brakes and lights are all soldered.
