Summary

Louisiana adopts the National Electrical Code via the Louisiana State Uniform Construction Code, setting consistent permit and inspection standards for solar PV installations. Local jurisdictions issue permits but must apply the state-adopted electrical and structural codes uniformly.

A. For purposes of this Section, "solar collector" means any device or combination of elements which relies on sunlight as an energy source. B. No person or entity shall unreasonably restrict the right of a property owner to install or use a solar collector. C. The provisions of this Section shall not supersede zoning restrictions, servitudes as provided by Civil Code Article 697 et seq., or building restrictions, as provided by Civil Code Article 775 et seq., which require approval prior to the installation or use of solar collectors. D. The provisions of this Section shall not apply to property or areas which have been identified as historic districts, historical preservations or landmarks by any historic preservation district commission, landmarks commission, or the planning or zoning commission of a governing authority.

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.

Violations & Penalties

Unpermitted solar installation: stop-work orders, fines, removal/correction orders, and potential utility refusal to interconnect the system.
