EXPEDITED PERMIT PRoCESS FoR SMALL.SceIT PV SYSTEMS MICRo. INVERTER e information in this guideline is intended to help local jurisdictions and contractors identify when PV system installatjons are simple, needing only a basic review and when an installation is more complex. It is likely that 50%-75% of all residential sysrems will comply with these simple crireria. For projects that fail to meet the simple criteria, resolution steps have been suggested to provide as a path to permit approval. Required Infonnation for Peflnit: 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'perimeter space at ridge and sides may not need separate nre service review 2. Electrical diagram showing PV array configuration, wiring system. overcurrent protection, inverter, disconnects. required signs, and ac connection ro building (see supplied standard electrical diagram). 3. specification sheets and installation manuals (if available) [or all manufactured components including, but nor limited ro, PV modules. inverter(s). combiner box. disconnects, and mounting system. Step 1 : Structural Review of PV Array Mounting System / ts the array to be mounted on a defrned, permitted roof structurez ZYes Etto IJ No due to non-compliant roof or a ground mount, submit completed worksheet lor the structure WKSI . RooJ Information: l. Is the roofing type lighrweight (Yes = composition. lightweight masonry, metal, etc ..)yes If No, submit completed worksheet Jor roof sffucture wXS, (No = heavy masonry, slate, etc. . .) 2.

Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagram) In order for a PV systcm to be considered for en expeditcd p€rmit process, the following must apply: l. PV modules, utility-interactive inverters, and combiner boxes are identihed for use in PV systems. 2. The PV array is composed of 4 series strings or less per inverter 3. The total inverter capacity has a continuous ac power output 15,440 watts or less 4. The ac inrerconnection point is on the load side of service disconnecting means (690.64(8)). 5.
