Just to demonstrate the variance between jurisdictions, I recently did a
system in a rural county in Oklahoma. There was no inspection process
and folks were allowed to do their own wiring without a license.
Essentially there was no AHJ at all. The utility did require a single
line diagram, but that was about it, for that little corner of the still
wild west.

Marco,
Here in Vermont no schematic is required for residential PV system
installations. There is a simple CPG process (Certificate of Public
Good, which is automatically acquired within 11 business days after
registering) for all systems 10kW and under. Larger residential
systems can take about 6 weeks to get a CPG. Commercial installations
do not necessarily require a schematic before being permitted.
Our State Incentive Grant program (currently unfunded and suspended)
has a review of system documentation including a simple one-line
drawing before the Incentive is paid out after completion and
commissioning of the system.
About 10% of residential systems that receive an incentive also
receive an inspection, these inspections happen well after the system
is commissioned. The incentive was at 55 cents per DC Watt when the
program closed at the end of 2012. This program will most likely open
up again fairly soon at about 50 cents/Watt.
Note that Vermont does not require that electrical work on residences
be done by licensed electricians, except in the City of Burlington. In
order to be eligible for the Incentive Grant the PV system has to be
installed by a Vermont Solar Partner. In this way the state has some
control over the quality of net metered PV installations. Off grid
systems receive no incentives and are not being reviewed by any
authorities.
Best,
Dave Palumbo

We've got a strange situation in our little Aloha State. While the
counties of Maui, Kauai and the Big Island require a PV permit package
to include system design schematics with the package, the largest
county in the state by population, the island of O'ahu, does not
require any schematic for residential systems. This blows my mind.
I'm wondering if there are other AHJs out there on the Mainland where
no schematics are required to obtain a PV permit.
Any feedback would be appreciated.
Thanks,
marco
