The information in this guideline is intended 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 al residential <br />systems will comply with these simple criteria. For projecls that fail to meet the simple criteria, resolution steps have been <br />suggested to provide as a path to permit approval. <br />t- .. . t u t '" , 1 t t t t .t tfl.

This drawing need not be exactly to scale, but it <br />should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings <br />with a 3'perimeter space at ridge and sides may not need separate 6re service review. <br />2.

PV modules, utility-interactive inverters, and combiner boxes are identifled for use in PV systems. <br />2. The PV array is composed of 4 series strings or less per inverter. <br />3. The tolal 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)). <br />5.
