In the end I used a CA company up near Shasta. I found there were other places for the same gear slightly cheaper but this place had better customer service. The package included the racking, all the paperwork I needed, panels, inverter, etc. The only things it did not include was the #6 ground wire and the conduit.
Just had my county inspector check it and he was very happy. Yippy! So I have an 11 year old 3.15 kW DC system south facing and now a new 6.4 kW DC system half East and half West, (no more south available)
I ended up going with an SMA string inverter, 6.0-US and it is great. Everyone seems to recommend enphase or the DC optimizers but I think simplicity is better, one string inverter. And as I have no shading issues, its cheaper too. A test has already confirmed my system beats the PV Watts expected production by about 13% for my test day.
In the end I'm sure I could have done the system cheaper buying used or piecemeal parts but after tax rebate this will still come out around $1/watt. I'm happy.
