. EXPEDITED PERMIT PROCESS FoR SMALL-SCALE PV SYSTEMS MICRO-INVERTER the informarion in rhis guideline is inrended [o help local jurisdicrions and conrractors idenrify when PV s]srem insEllarions are simple, needing only a basic review and when an insallation is more complex. lL is likely rhar 50 %'75 of all residenrial systems will comply with these simple criteria. For projects thal fail ro meer rhe simple crireria, resolurion steps have been suggested to provide as a path to permit approval. Requbed Infonnation for Permit: l.
