Yes, personal reason, but linked to Code reasons. For the following reason:
The GEC must be "continuous and unspliced" all the way thru conduit, alL the way to MAIN or gr. rod!. With planning, this is doable.
Conduit requires stranded (for Code, or practical reason, not sure, but you need stranded in conduit )
I use THWN-2 stranded #8 GREEN....the slick insulation is great for conduit.

As INETDOG said......YEs, in theory, one single long , and twisty , and repetitive conductor could bond all metal up on the roof.
Some solar guys think all bonding with a conductor needs to be "continuous and unspliced". Not true. They conflate GEC with EGC.
In practice if protected (under panels) #10 BARE, solid, COPPER EGC IS CHEAP AND EASY FOR FRAMES AND RACK: REMEMEBER: YOU WILL HAVE TO STRIP INSULATION AT EVERY DAMN LUG....
