EXPEDITED I'ERMIT IROCESS FOR SMALL-SCALE I'V SYSTEMS MICRO-INVERTER The informarion in rhis guideline is intended to help local ju risdicrions and conrracrors idenrify when PV sysrem insrallations 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 wirh these simple criteria. For projects that lail to meet the simple crireria, resolution steps have been suggesred to provide as a path to permit approval. Required lnformation for Permit: l. Site plan showing location of major components on the property. This drawing need not be exactly to scale, but ir 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 not need separate hre service review. 2. Elecrrical diagram showing PV array conhgurarion, wiring system, overcurrenr prorecrion, inverrer, disconnects, required signs. and ac connection to building (see supplied standard electrical diagram). 3. Specincarion sheets and installation manuals (if available) for all manufactured components including, but not limited to, PV modules, inverrer(s), combiner box, disconnects, and mounting system Step I : Structural Review oI PV Array Mounting System Is the array to be mounted on a defined, permitted roof structure?
