<br />The information in this guideline is inlended to help local jurisdictions and contractors identify when Pv system installations
<br />are simple. needing only a basic review and when an installation is more complex. It is likely that 50%-75% of all residential
<br />systems will comply with these simple criteria. For projects that fail to meel the simple criteria, resolution steps have been
<br />suggested to provide as a path (o permil approval.

<br />l. Site plan showing location of major components on the property This drawing need nol be exactly to scale. but it
<br />should represent relative location oI components at sire (see supplied example site plan). PV arrays on dwellings
<br />with a 3' perimeter space at ridge and sides may not need separare hre service review.
<br />2 Electrical diagram showing PV array configuration, wiring system, overcurrent protection, invener. disconnects,
<br />required signs, and ac connection to building (see supplied standard electrical diagram).
<br />3. Specihcation sheets and insElladon manuals (ii available) for all manufactured components including, but not
<br />limited to, PV modules, inverter(s), combiner box, disconnects. and mounting system.

<br />ln order for a Pv slEtem to t e considered for an expedited p€rmit process, the following must apply:
<br />L Pv modules, utility-interactive inverters, and combiner boxes are identified for use in Pv systems.
<br />2. The PV array is composed of 4 series strings or less per inverter.
<br />3. The rotal inverter capacity has a continuous ac power output 13,440 watts or less
<br />4 The ac interconnection point is on the load side of service disconnecting means (690.64(8)).
