MC-4 Parallel Y Cables

Solar panels can be wired together in either series (+ to -) or parallel (+ to +) configurations. Wiring two panels in series effectively turns them into one larger panel, which can simplify installation but makes the array more susceptible to shading — if any part of either panel is shaded, total array output drops dramatically.

A parallel configuration solves this problem: the output of one panel isn't affected by the output of the other, which can make your array more efficient in partial shade — common for vehicles that move around a lot.

This parallel Y-cable makes connecting two panels in parallel simple, and can improve your system's overall power output. Looking to connect three panels in parallel? Check out our 3-to-1 parallel cables instead.
