[RE-wrenches] Multi-structure PV install

[Jason Lombard]

Kurt,

I worked on a elderly housing site in northern Ca in which we connected to
the main service on each structure (total of 12) or building. These were
about 2kw each and combined over three or four apartments and in some cases
a full flat roof with a tilt up to 6kw. All of them were grid tied so a
breaker in the panel was easy to put together the system. Labeling was
accomplished by first the NEC and by PG&E requirements and disconnects were
installed by the service. The nice thing about CA is they use only one meter
which is a bi-directional digital system so the production meter was not
needed.

Hope this helps a bit.
