EXPEDITED PERMIT PRoCESS FoR SMALL-SCALE PV SYSTEMS MICRO-INVERTER' fhe informarion in this guideline is inrended ro help local jurisdicrions and conrractors idenrify when pv sysrem insa ationsare simple, needing only a basic review, and when an insEllation is more complex. Ir is likelyihat 50 % -75% ot all residenrial systems will comply with these simple criteria. For projects thar fail to meer rhe simple criteiia. resolurion sreps have been suggested lo provide as a parh ro permir approval.
