EXPEDITED PERMIT PROCESS FoR SMALL-SCALE PV SYSTEMS STANDARD STRINC SYSTEM The information in this guideline is intended to help local jurisdictions and contractors idenrify when PV sysrem insallarions are simple, needing only a basic review andwhenan insEllation is more complex. lt is likely that 50 -75% of all residential systems will comply with these simple criteria. For projecB that fail ro meet rhe simple criteria, resolurion steps have been suggested to provide as a path to permit approval. Required Information for Permit: l. Site plan showing location of major components on the property. This drawing need not be exactly to scale. but it should represen( relative location of components at site (see supplied example site plan). PV arrays on dwellings wirh a 3'perimeter space at ridge and sides may nor need separate hre service review. 2. Elecrrical diagram showing PV array confrguration, wiring system, overcurrenl protection, inverret disconnects,srequired signs, and ac connecrion to building (see supplied standard elecrrical diagram) .. a{ W. Dur nor 9 l. Specihcarion sheets and installation manuals (if available) for all manufactured components inclu limited to, PV modules. inverter(s), combiner box, disconnects. and mounting "'*T c Step 1 : Structural Review of PV Array Mounting System It\szo rt\1 ts the array to be mounted on a defined, permitted roof structure?

Step 2: Electrical Review of PV System (Calculations for Electrical Diagram) In order for a Py s]rstem to bâ‚¬ considered for an expedited pâ‚¬rmit pnoccss, 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 inverter 3. The total inverter capaciry has a continuous ac power output 13,440 Warts or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(8)). 5. One of the sandard electrical diagrams (El.1. El.l a. El .l b, or El.tc) can be used to accxrately represent rhe Pv system. lnteractive PDF diagrams are available at www.solarabcs.orgi permit(ing. Fill out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the applicant understand each blank to fll in. U the electrical qlste7n is more complex than the standard electrtcal dtagram can efJectively communicate. provide an alternatil)e diagram with appropriate detail. 2 EXPEDITED PERMIT PRoCESs FoR PV SYsTEMS 20l(" ?s=r
