<br />EXPTDITED PERMIT PnocESS FoR SMALL-ScnIc PV Sysrrus. STANDARn STnING SYSTEM
<br />The informa.tion in this guideline is intended to help local jurisdictions and contractors identifu when PV sysrem installations
<br />are simple,'needing only a basic review, and when an installarion is more complex. It is likely rhar 50 7o-75% of all residential
<br />systems will comply with these simple criteria. For projects rhat fail to meet the simple criteria, resolution steps have been
<br />suglgesred to provide as a path to permit approval. / ,,,i ..r,, ,,, .

<br />maximum spacing allowed based on maximum design wind speed)
<br />545 ft2
<br />2.56 lbsi ft:
<br />IJ distributed weight of the PV system is greater than 5 lbs/fr'z, see WKSI.
<br />Step 9: Electrical Review of PV System (Calculations lor Electrical Diagram)
<br />In order for a PV system to be considered for an expedited permit process, the following must apply:
<br />I . PV modules, utility-interactive inverters, and combiner boxes are idenrifred 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 point is on the load side of service disconnecting means (690.64(8)).
<br />5. One of the standard electrical diagrams (El.l, El.la, El.lb, or El.lc) can be used to accurately represenr the PV
<br />system. Interactive PDF diagrams are available at www.solarabcs.or$/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. IJ the electrical system is more complex than the standard electrical diagram can effectively
<br />communicate, provide an alternative diagram with appropriate detail.
