EXPEDITED PERMIT PROCESS FOR SMALL.SCALE PV SYSTEMS MICRo-tNVERTER The informarion 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 installation is more complex. It is likely that 50% -75% of all residential systems will comply with these simple criteria. For projects that fail to meer rhe simple criteria, resolurion steps have been suggested to provide as a path to permil approval. Required InJormation fot Pefinit: t. Sire plan showing location of major components on the property. This drawing need not be exactly to scale, but il 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 connecrion lo building (see supplied standard elecrrical diagram). 3. Specihcarion 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 of PV Array Mounting System Is the array to be mounted on a defined, permitted roof structure? Eyes flno U No due to non-compliant rool or a ground mount, submit completed worksheet.for the structure WRSI. Roof Infoffiation: l. ls the roohng type lightweight (Yes = composition. lighrweighr masonry, metal, etc )COI\,4P,SHINGLE IJ No, submit completed worhsheetfor rool structure wKSl (No = heqvy masonry, slate, etc.. .) Yes E tto IJ No, submit completed worksheet Jor rool structure WKSI 2. Does the roof have a single roof covering? FLASHING Y CAULK ineered producr designed to mounr PV modules with no more than an 18" gap Yes ! no l Is the mounting structure an en If No, provide details oJ sttuctural attachment certtjed by a design proJessional. 2. For manufactured mounting systems, fill out information on rhe mounting system below benearh the module frames? b. Total [reigh c Toral Number of Attachment Points 34 d. Weighl per Attachment Point (b + c)27 .54 e f. Total Surface Area of PV Modules (square feet) g. Disrributed Weighl of PV Module on Rooi (b + l) a.

Step 2, Electrical Review o[ PV System (Calculations [or Electrical Diagram) In order for a Pv system to be considered for an expedited permit process, the following must apply: L PV modules. uriliry-inreractive inverters, and combiner boxes are identified For use in PV systems. 2. The PV array is composed of 4 series strings or less per invertet 3. The tolal inverter capacily has a continuous ac power oulput 13.440 Watts or less 4. The ac interconnection poinr is on the load side of service disconnecting means (690.64(8)). 5. One ofthe srandard electrical diagrams (E L I , E l I a, E L I b, or E I I c) can be used to accurately represenl [he PV system. lnteractive PDF diagrams are available at www.solarabcs.org/permifting. Fill out the standard electrical diagram completely. A guide to the electrical diagrqm is protided to help the applicant understand each blank to jll in. IJ the electrical system is more complex thqn the standard electrical diagram can efJectively communicate, provide an alternative diagram with appropriate detail. 2 EXPEDITED PERMIT PROCESS FOR PV SYSTEMS MICRO'INVERTER 3.
