Thanks,
It really is not that difficult now a days with the microinverters. you plug the units into premade cabling. There is no high voltage DC of the string inverters or the math to design the strings etc. Its basically adding a branch circuit. The manual takes you through everything you need to know.
While I did all the electrical myself I would agree if you are not solid on doing this you should just trench, run the wire and then pay a electrician to make the connection as already pointed out.
The racking is also easy, you go to ironridge and run their program, put in your panels and the number of them, wind load speeds required and it does the work and you print the stamped engineering data to provide your building department for your permit. It's just a big erector set. You follow the instructions in the assembly manual.
I am not saying it is not alot of work but the design work is all done for you. But like most DIY if you don't mind doing it yourself the rewards can be great. To have the system installed was quoted at $63,000 We did it for $25,000. After the 30% tax refund from it we ended coming in with the $17,500 As I said. A great place to deal with is wholesalesolar, This is where we got our stuff and they were very helpful. They sell kits for it of about any size you want.
