I cannot for the life of me figure this out. I had my 2 solar panels on the ground and now put them on a fence. They are now end to end; not side by side like in all the illustrations.

So, the label ends are facing each other. I will put the "in to solar in the bottom right one, .... so now the top right is the "out to the next panel" one. Which do I connect it to on the left one? can it go in the left top which would be easier to plumb, or does it always have to go in the bottom...

I do hope someone can understand what I am doing...(obviously I don't)

Thanks,
Ellie
