Exempts solar energy systems from building fees.

S 231 exempts solar energy systems certified under New Jersey's current property tax exemption law (P.L.2008, c.90) from municipal building fees and state construction permit charges. It directly affects homeowners and businesses installing solar systems by removing costs for permits, plan reviews, and related fees. The bill updates outdated references in a 1985 law to align with the active 2008 property tax exemption statute, reinstating a fee exemption that expired when the original reference lapsed. This change makes solar installations more affordable by eliminating specific administrative fees, without altering property tax rules or creating new requirements.
