l l <br />ll <br />EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS <br />MICRO-INVERTER <br />The information in this guideline is intended to help local jurisdictions and contractors identify when PV system installations <br />are simple, needing only a basic review, and when an installation is more complex. It is likely that 50%-75% of all residential <br />systems will comply with these simple criteria. 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 Information for Permit: <br />1. 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? Yes <br />If No due to non-compliant roof or a ground mount, submit completed worksheet for the structure WKS1. <br />Roof Information: <br />Mounting System Information: <br />1. Is the mounting structure an engineered product designed to mount PV modules with no more than an 18” gap <br />beneath the module frames? Yes <br />If No, provide details of structural attachment certified by a design professional. <br />2. For manufactured mounting systems, fill out information on the mounting system below: <br />a. Mounting System Manufacturer Seg solar Product Name and Model# SEG-400-BMD-HV[400W] <br />b. Total Weight of PV Modules and Rails 722.68 lbs <br />c. Total Number of Attachment Points 28 <br />d. Weight per Attachment Point (b÷c) ___25.81lbs (if greater than 45 lbs, see WKS1) <br />e. Maximum Spacing Between Attachment Points on a Rail 72 inches (see product manual for maximum <br />spacing allowed based on maximum design wind speed) <br />f. Total Surface Area of PV Modules (square feet) 294.20 ft2 <br />g. Distributed Weight of PV Module on Roof (b÷f) 2.45 lbs/ft2 <br />If distributed weight of the PV system is greater than 5 lbs/ft2, see WKS1. <br />Step 2: Electrical Review of PV System (Calculations for Electrical Diagram) <br />In order for a PV system to be considered for an expedited permit process, the following must apply: <br />1. PV modules, utility-interactive inverters, and combiner boxes are identified for use in PV systems. <br />2. The PV array is composed of 2 series strings or less per inverter. <br />3. The total inverter capacity has a continuous ac power output 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 (E1.1, E1.1a, E1.1b, or E1.1c) can be used to accurately represent the PV <br />system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. <br />Fill out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the applicant <br />understand each blank to fill in. If the electrical system is more complex than the standard electrical diagram can effectively <br />communicate, provide an alternative diagram with appropriate detail. <br />2 EXPEDITED PERMIT PROCESS FOR PV SYSTEMS — MICRO-INVERTER <br />1101 W 6th St <br />03/21/23
