I'd be wiring in series for 74v, not 24v. I have a local place where I can get 8 gauge for 65 cents/foot, thanks for the link though. I love Princess!
In Bulk the voltage on the panel to controller wiring will be set by the MPPT near the Vmp of the panels (added in series) so that would be more like 60 volts with the two panels. (You still use the added Vocs for controller voltage limit though)
In Float you can also get a higher current to run any loads but no more than one panel's Isc if they are in series.
Good price for the #8. IMO use that! Some panels don't have wiring boxes on the back, just the wires with MC4s. (and the wire is al not cu on mine) I wonder about the store-bought with MC4 wire if it is al too :( I use the cu #8 connected to the cut-off al pigtails with wirenuts for my portable set-ups
