For projects that fail to meet the simple criteria, resolution steps have been <br />suggested to provide as a path to permit approval. <br />Required lnformation for Pennit : <br />I . Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it <br />should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings <br />with a 3'perimeter space at ridge and sides may not need separate fire service review. <br />2. Electrical diagram showing PV array configuration, wiring system, overcurrent protection, inverter, disconnects, <br />required signs, and ac connection to building (see supplied standard electrical diagram). <br />3. Specification sheets and installation manuals (if available) for all manufactured components including. but not <br />limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. <br />Step 1 : Structural Review of PV Array Mounting System <br />Is the array to be mounted on a defined, permitted roof structure? Elyes EIno <br />I,f No due to non-compliant roo"f or a ground mount, submit completecl worksheet Jor the structure WKSI. <br />Roof Information: <br />l. Is the roofing type lightweight (Yes = composition, lightweight masonry, metal, etc...)Yes <br />If No,submitcompletedworksheetforroof structure\RSl (No = heavymasonry.slate,etc...). <br />2. Does the roof have a single roof coveringZ Zyes Euo <br />If No, submit completed worksheetfor roof sffucture WKSI. <br />3. Provide method and type of weatherproofing roof penetrations (e.g. flashing. caulk).- <br />M ount ing Sy st em Informat ion : <br />l. Is the mounting structure an engineegld product designed to mount PV modules with no more than an I8" gap <br />benearh the module frames? EIyes f]no <br />If No, provide details of structural attachment cerilrted by a design professional. <br />2. For manufactured mounting systems, fill out information on the mounting system below: <br />a.MountingSvstemManufacturer-ProductNameandModel# <br />b.

PV modules. utility-interactive inverters, and combiner boxes are identified 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 13,44O Watts or less <br />4. The ac interconnection point is on the load side of service disconnecting means (690.64(B)). <br />5. One of the standard electrical diagrams (El.l, El.la, El.lb, or EI.lc) can be used to accurately represent the PV <br />system. lnteractive PDF diagrams are available at wwwsolarabcs.org/permirting. <br />Fill out rhe sttutdard electical clittgram contpletell' ,4 guide to the electrit'al diagrun is provided to help the ultplicunt <br />understancl each bltmk to.fill irt.
