Full Breakdown

Under La. R.S. 40:1730.21 et seq., the Louisiana State Uniform Construction Code Council adopts the IRC, IBC, and NEC governing rooftop and ground-mount solar PV systems. Permits are required for all grid-tied installations, and electrical work must be performed by a licensed electrician under the State Licensing Board for Contractors when the project exceeds $10,000. Interconnection follows the Public Service Commission net metering rule applicable to investor-owned utilities. Plan review covers structural attachment, electrical sizing, rapid shutdown compliance, and grounding. Local building departments enforce the state-adopted code without authority to weaken it.
