. <br />EXPEDITED PERMIT PRoCESS FoR SMALL-SCALE PV SYSTEMS <br />MICRO-INVERTER <br />The informalon in this guideline is intended ro help local jurisdictions and conrractors idenify when PV sysrem insallations <br />are simple. needing only a basic review and when an installation is more complex. Ir is likely that 50% -75% of all residenrial <br />systems will comply with these simple criteria. For projecrs that fail ro meet the simple criteria. resolurion steps have been <br />suggested to provide as a path ro permir approval. <br />Reqdreal Inforfiation fot Pefinit: <br />1. Site plan showing locarion of maJor components on rhe properry. This drawing need nor be exacrly ro scale. bur ir <br />should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings <br />wirh a 3'perimeter space at ridge and sides may not need separale hre service review. <br />2. Electrical diagram showing PV array confrguration, wiring system. overcurrenr protecrion, inverter, disconnects, <br />required signs. and ac connecrion ro building (see supplied standard elecrrical diagram). <br />3. Speci6cation sheets and installation manuals (iF available) for all manufacrured componenrs including, bur nor <br />limited to, PV modules, inverter(s), combiner box. disconnects, and mounring sysrem. <br />Step 1 : Structural Review of PV Aray Mounting System <br />Is the array to be mounted on a de6ned, permitted rcof structure? EyesEno <br />lJ No due to non-compliant rooJ ot a ground mounl submit completed wotksheet Jor the structure WKSI . <br />Roof lr{oflnatiofl: <br />l. ls the roohng type lightweight (Yes = composirion, Iighrweighr masonry meral, erc. .)Yes <br />IJ No, submit completed worksheet for roof structure WKSI (No = heayy masonry, slate, etc. ..) <br />2. Does the roof have a single roof coveringz Eyes EUo <br />f No, submit completed worhsheet Jor roof sfiucture WKS I . <br />3. Provide merhod and rype of weatherproohng roof penerrarions (e.g. flashing, caulk)Flashin <br />M ounttng Ey st efi Informati on : <br />l. Is the mounting structure an e_!Sineered product designed to mount PV modules with no more than an 18" gap <br />beneath the module frames? LjYes LINo <br />If No, provid.e details oJ structural attachment certified by a design WJessionaL <br />2. For manufactured mounting sysrems, hll out information on the mounring system below: <br />a. N4ounting Sys tem Manufacrurer SWH producr Name and 14o6"11Solar Mount <br />b. Total Weight of PV Modules and Rails <br />c. Total Number of Attachment Points <br />598 bs <br />18 <br />d. Weight per Atrachment Point (b+c) 3322 lbs (rfgreater than 45 lbs, see WlGl) <br />e. N4aximum Spacing Between Arrachment Points on a Rail 72 nches (see product manual for <br />maximum spacing allowed based on maximum design wind speed) <br />f. Toral Surface Area of PV Modules (square feet)229.U <br />g. Distribured Weighr of PV Module on Roof (b + f)2.61 Ibsi ft'? <br />IJ distributed weight ol the PV system is greatet than 5 lbste, see WKSI . <br />Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagram) <br />ln order for a PV s)6tem to be consider€d for an expedited permit process, the following must apply: <br />l. Pv modules, utility-interactive inverters. and combiner boxes are identihed for use in Pv systems. <br />2. The PV array is composed of 4 series strings or less per inverter. <br />3. The total inverter capacity has a continuous ac power output 13,440 Watts or less <br />4. The ac interconnection poinr is on the load side of service disconnecring means (690.64(8)). <br />5. One of rhe sEndard elecftical diagrams (El .l , E l .l a, E l .1b, or E1 .1c) can be used ro accurarely represenr rhe Pv <br />system. lnteractive PDF diagrams are available at www.solarabcs.org/permifting. <br />Fill out the standard electricd.l diagram completely. A g\id.e to the electrical diagram is ptovided to help the arylicont <br />understand each blank to lll in. If the electrical system is morc conpler than the standard electrical diagram can elfectively <br />communicate, proyide an alterna.tiye dio.gran with awropiate detail. <br />2 EXPEDITED PERMIT PROCESS FOR PV SYSTEMS - MICRO-INVERTER
