ExpTDITEO PSRMIT PROCESS FOR SUnII-SCALE PV SySTeuS MICRO-INVTRTER The information in this guideline is intended to help local jurisdictions and contractors identify when PV system installations are simple, needing only a basic review and when an insmllation is more complex. It is likely that 50%-75% of all residential systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolution steps have been suggested to provide as a path to permit approval. Required Information for Permit : t. Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings with a 3' perimeter space at ridge and sides may not need separate fire service review. 2. Electrical diagram showing PV array configuration, wiring system, overcurrent protection, inverter, disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specifrcation sheets and installation manuals (if available) for all manufactured components including, but not limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. Step 1: Structural Review o[ PV Array Mounting System Is the array to be mounted on a defrned, permitted roof structuref Eyes flno I!

Step 2: Electrical Review of PV System (Calculations [or Electrical Diagram) In order for a PV system to be considered for an expedited permit pnocess, the following must apply: l. PV modules, utility-interactive inverters, and combiner boxes are identified for use in PV systems. 2. The PV array is composed of 4 series strings or less per inverter. 3. The total inverter capacity has a continuous ac power output 13,44O Watts or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(8)). 5. One of the standard electrical diagrams (El.l, El.la, E1.lb, or El.lc) can be used to accurately represent the PV system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. Fill ottt tlw standard electrical cliagrant cotnpletely. A guide to the electrical diagratn is provided to help tlrc applicart understand each blank to fill in. lf the electrical system is more contplex than the standard electrical diaE arn can ef.fectively communicate. provide an alternative diagratn wtth appropriate detatl. 2 IXI,EDII.ED PERI\4I-I.
