EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS STANDARD STRING SYSTEM The information in this guideline is inrended to help local jurisdictions and conLractors identify when PV system insEllarions are simple, needing only a basic review. and when an insEllation is more complex. It is likely that 50%-75% of all residential systems will comply wirh these simple criteria. For projects that fail ro meet the simple criteria, resolurion sreps have been suggesled lo provide as a path to permit approval. Requireil Infonnation for Permit: l. Site plan showing location of major components on the property This drawing need not be exactly to scale, bur ir should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings with a 3 perimeler space at ridge and sides may not need separate fire service review. 2. Electrical diagram showing PV array conhguration, wiring system, overcurrent protection, invener, disconnects, required signs, and ac connection ro building (see supplied standard electrical diagram). 3. Specihcation sheets and installation manuals (if available) for all manufactured components including, but nor limited to, PV modules, inverrer(s), combiner box, disconnects, and mounting system. Step 1 : Structural Review o[ PV Array Mounting System ls the array to be mounted on a defined, permitted roof structure?Yes E No U No due to non-coupliant roo.f or a ground mount, submit completed worksheetJor the structure WKSI Roof Infonnation: 1. Is the rooflng type lightweight (Yes = composition. lightweight masonry. metal, etc. .) Comp shingle YES If No, submit completed worksheet for roof stucture WtrSI fNo = heayy masonry, slqte, etc...) 2 Does the roof have a single roof coveringt Elyes n r,lo If No, submit completed worhsheet Jor roof structure WRSI. 3.

Step 2: Elecvical Review of PV System (Calculations for Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the following must apply: l PV modules, utility-interactive inverters, and combiner boxes are identifred for use in PV systems 2. The PV array is composed of 4 series strings or less per invefter 3. The toral inverter capacity has a continuous ac power output 13,440 Watts or less 4. The ac interconneclion point is on the load side of service disconnecting means (690.64(8)). 5. One of the standard electrical diagrams (El.l. El.la. El.lb. or El.lc) can be used to accurarely represenr rhe PV system lnteractive PDF diagrams are available at www.solarabcs.org/permitting. FilI out the standard electrical diagram completely. A guide to the electrico.l diagram is proyided to help the arylicant understand each blank tofll in. If the electrical system is more complex than the standatd elecffical diagram can efJectively communicqte, proyide an slternatiye diagram with appropriate d.etail. 2 ExpEDrrED PERMTT PRocEss FoR PV sysrEMs M oltflting Sy stem Infonnatton: l.
