EXI'EDITED PERMII' PROCESS FOR SMALL.SCALE I'V SYSTTUS STANDAtlD STRING SYSTEM The lnlormation in this guideline rs inlended to help local Jurisdicrions and conrractors idenrify when pV sysrem insrallarions are srmple, needing only a basic review and when an rnsrallarion rs more complex l! is likely Lhar 50%-75% of all residential systems will comply with these slmple critena For proJecrs that fail to meet the simple crirena, resoturion steps have been suggested to provide as a parh to permit approval.
