I've never hooked up solar panels before and now face two different connectors: T4 and MC4. Is one better than the other or more suitable for particular applications? And most important, do they plug into one another, in other words, can you have a mixed system where, for example, a T4 connector on a panel must mate to a MC4 connection on an extension cable?
If you are doing a rooftop permanent install you would not need connectors. Most panels have a junction box on the back which would give you access to a terminal strip. Remove the pigtail wires and hook direct to the terminal strip.
I have two panels that I can remove and set in the sun. I cut the MC4 connectors off and replaced them with Anderson Powerpole SB50 connectors.
