MC Cable connections
I'm adding 3 more solar panels to my array. Because of availablility, I'm adding BP Solar panels instead of the original Matrix panels. In my original configuration, I've wired my Matrix in series using 6 gauge copper wire, pig-tailed from the box w/10 guage wire. I'm wondering if I should do the same for the BP panels or if I should use the MC cable connectors that are factory made. Any suggestions? For clarification, I ran the + side of the 6 ga from my pv breaker box to each individual panel (about 40 feet to the furtherest panel) and pigtailed the connection at the junction box. My - side is 6 ga, one wire run with all the panels spliced to it. Seems to me I'm going to have to splice to the mc connector at some point so why not just run the 6 ga all the way to the junction box at the panel? I'm saving 72 bucks on the cost of the cable. I already have the 6 ga wire to do the runs, I think. I may have to buy a little more. Thanks for the help, group.
