Ground wire change?

[Sterling9250]

I have an existing solar array of 6 panels wired in series. I am going to be changing that to two arrays of 3 panels connected in parallel. Do I need to change the way it is grounded? Should I for example have the ground wire follow the neutral instead as illustrated in the picture?

As long as all 6 frames are connected together, it does not matter.

Thank you!
