EXPED1TED PERMIT PROCESS FOR SMALL.SCALE PV SYSTEMS, STANDARD STRINC SYSTEM The information in this guideline is intended to help local jurisdictions and conractors identiry when PV system installations are simple, needing only a basic review and when an installation is more complex. lt is likely that 50 % -75 % of all residential systems will comply with these simple criteria. For projects rhar fail to meet the simple criteria, resolution steps have been suggested ro provide as a path to permit approval. Requbed hforrnation for Permit: l. 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'perimerer space at ridge and sides may not need separate hre service review. 2. Electrical diagram showing PV array configuration, wiring system, overcurrent protection, inverte( disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 5. Specifrcarion sheets and insEllation manuals (if available) for all manufactured components including, but nor 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?ves E r,lo U No due to non-compltant roof or a ground mount, submit completed worksheet lor the structure WKS I Rooj lr{onnation: l. Is the roofing type lighrweight (Yes = composition, lightweight masonry, metal, etc...)YES If No, submit completed worksheet lor rooj structure WKSI (No = heavy masonry, sbte, etc. . .) 2. Does rhe roof have a single roof coveringu Eves !no If No, submit completed. worksheet for rcof structure WKSI . 3. Provide method and rype of weatherproofing roof penerrations (e.g. flashing, caulk)UNIRAC FLASHKIT. CAULK M offiting Sy s t em Informat ion : L ls the mounting structure an beneath the module frames?

Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the following must apply: 1. Pv modules, utility-interactive inverrers, and combiner boxes are idenrihed for use in Pv sysrems. 2. The PV array is composed ol4 series strings or less per inverter. 3. The toral inverrer capacity has a continuous ac power output 15,440 Watts or less 4. The ac inlerconnection point is on the load side of service disconnecting means (690.64(8)). 5. One of rhe standard electrical diagrams (El.1, El.l a, El .l b, or El.lc) can be used to accurarely represenr rhe PV system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standdrd electical diagram completely. A guide to the electrical diagram is provided to help the applicant understand each blank tofU in. U the electTical system is more complex than the standard electrical diagram can effectively communtcate, provide an alternative diagram with appropriate detdil. 2 EXPEDITED PERMIT I'}ROCESS FOR PV SYSTEMS a b c d e f.
