Over at the Arizona Wind & Sun forum, a user SolarPowered, documented his work for a client out West, I thought in California but I'm not sure. You can at least follow the installation that he did and possibly ask a few questions too.

Even if you're not going to do the work yourself, it is very important to know the fundamentals and if things are being done right. For example, on my installation, I hired a roofer to install the brackets. When he was starting I casually asked him why he didn't snap a chalk line. He said, "I've been doing this for 20 years and I don't need a chalk line." OK, but ... you guessed it, when I went up and looked it was as crooked as a sidewinder in the Sahara. I ended up having to loosen everything and readjust as best I could to get it at least close to straight. He also left me to haul the panels up to the roof myself, backwards up a ladder thinking it is $1000 if I drop this and I sure hope the wind doesn't pick up right now. I got worried about the electrician when he said, "Wow, it's been awhile since I bent conduit." So I finally had to, as the guys in the electrical store kept saying, "fire the electrician," because when I looked him up his license had lapsed. Just an oversight but it would have cost me the $18K rebate. So yes, it still can be a project even when you hire people. In the end, I found a great electrician who came in and did the last bit of the project.
