I'm working on a large grid-tied PV installation and could use some advice on connecting the system to the utility. It's too large to connect via a backfed breaker on the existing 200-amp load center, so what other options exist? I have read the Code Corner in HP112 about supply-side taps, but I could use some additional guidance. I am a master electrician, and have installed few PV systems.

Existing load centers may not have enough room to make the necessary connections. The National Electrical Code (NEC) limits the number of conductors
