MC4 connectors are designed for series connections.
To use MC4 connectors in parallel, you need to buy a pair of Multibranch MC4 adapters and you need of course to have MC4 connectors on both panels. I think MC4 are soldered on the cable, so you have to either solder or crimp it somehow (after buying all the connectors and adapters).
