Again not sure if all wires need to be the same as in copper conductors 3/0-3/0-3/0, or 4/0-4/0-4/0, #6 insulated or Aluminum 4/0-4/0-4/0 or 250-250-250 mcm, #6 insulated Copper Ground? (noting that less voltage drop for a 4/0 copper or 250 mcm choices $$$ for copper not a big increase for AL to 20 mcm). I was told be the electric company that 3/0 copper would likely be sufficient.

This seams like a good deal but I am not sure the UL insulation is adequate. Local store has a 4/0-4/0-2/0 AL triplex UD for $2.64 a linear foot. This leaves the main conductors sizes and insulation type. My questions: 1) how much more conductor should I buy to make connections? 2) Granted I will use Schedule 40 in buried section do I need schedule 80 for the risers? 3) I will run a ground wire in conduit, likely #8 bare copper. 4' bottom of panel to ground +2.5' underground+170' horizontal +2.5' back up + 3.0 to bottom of panel= 170+12 = 182' and gives me my estimate for minimum conduit length.
