#6 bare to #10 stranded and other transition questions

[arcsum68]

Hi all,

I am self installing solar on my home. Just about done with racking and about to move onto installing SolarEdge optimizers and the panels.

I am sure the friend that is helping me with the electrical side knows most of this already, but I like to understand this stuff myself, plus he is not familiar with solar specific installations. I would also like to be able to pre purchase as much of the supplies as possible as to not inconvenience him.

I have 2 arrays (16 and 15 panels) that are about 6' from each other on 2 different planes.

My questions are
1. I will go from PV to THWN in jbox/emt to the panel. I know wire nuts are not good for this application. Can I use a terminal block for this purpose inside a sealed jbox?

2. What's the best way to transition from #6 bare wire to the stranded #10 ground in the jbox? Split bolt, buchanan, something else?

3. Will I be able to pass emt under an array to meet up with a jbox on the other side and have enough roof clearance?

If there's already a post with some information about this, please let me know. I dont mind reading, but was not finding anything.

Thanks!
