EXI,EDITED PERMIT I,RoCESS FoR SMALL_SCALE I,V SYSTEMS STANDARD STRING SYSTEIvI The informalion in this guideline is intended to help local jurisdictions and contractors identity when Pv system insrallarions are simple. needing only a basic review and when an insEllation is more complex. Ir is likely rhar 50% -75% of all residenrial systems wrll comply with these slmple cnteria. For projects that fa,l to meet the simple crireria, resolution sreps have been su&gested to provide as a parh to permit approval. Required Inlormation for Permit: l. Site plan showing iocation ol major components on the property. This drawing need not be exacrly ro scale, but tt should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings with a S perimeter space at ridge and sides may nor need separare nre service review 2. Electrical diagram showing PV array connguration. wiring system. overcurrent prorecrion, inverrer, disconnects. required signs, and ac connecrion to building (see supplied smndard elecrrical diagram). 5. Specihcation sheets and installation manuals (if available) for all manufactured components including, but nor limited to, PV modules, inverrer(s), combiner box, disconnecrs. and mounring system Step 1 : Structural Review o[ PV Array Mounting System ls tJre array to be mounted on a defined, permi$ed roof structure?

Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the following must apply: l. PV modules, utility-interactive inverters, and combiner boxes are identined for use in PV systems. 2. The PV array is composed of 4 series srrings or less per inverter f. The total inverter capacity has a conrinuous ac power output 13.440 watts or less 4.
