EXPEDITED PERMTT PROCESS FOR SMALL-SCALE PV SYSTEMS MtCRo.INVERTER The in[ormation in rhis guideline is intended to help local jurisdictions and contractors identify when PV syslem installarions are simple, needing only a basic review and when an installarion is more complex It is likely that 50%-75% of all resrdential syslems will comply wirh these simple criteria. For projects rhat fail to meet the simple criteria, resolution steps have been suggesred ro provide as a parh to permit aPproval. Required InJormation Jor Pennit: l. Site plan showing locarion of major componenrs on rhe property. This drawing need no( be exactly ao scale, but rt should represent relative location of componenrs ar sire (see supplied example sile plan) PV arrays on dwellings wirh a S perimerer space at ridge and sides may not need separate 6re service review 2.
