Oklahoma Plug-In Solar Laws

The former 1,200 W limit was explicitly AC

Unlike proposals that leave the measurement undefined, HB 4060 specified aggregate rated alternating-current output and capped it at 1,200 W. That is the inverter-side rating, not the combined DC nameplate rating printed on the panels. A package advertised with 1,200 W of panels could have a lower AC output. Several inverters would have to be counted together under the proposal.

The definition also required a standard grounded 120 V outlet and integrated anti-islanding or an equivalent function that prevents the building's electrical system from being energized during an outage. Those details describe a grid-parallel plug-in PV device. They do not describe a panel-only bundle or a solar generator supplying isolated loads through its own outlets.

Describe each of those points in the past tense. The Legislature did not enact the definition, threshold or outlet route. A retailer's claim that a system matches the former 1,200 W proposal does not establish permission to connect it today.

The proposed exemption would not have covered every provider

The engrossed bill defined an electric utility as a public utility providing retail service subject to Oklahoma Corporation Commission jurisdiction. The OCC says it regulates the rates and service reliability of Liberty Utilities, OG&E and Public Service Company of Oklahoma. It also says governmental utilities fall outside its regulation and many electric cooperatives have opted out of price regulation.

Even if HB 4060 had passed, its definition would have limited the proposed restrictions on approval, fees, extra equipment and agreements to the defined OCC-regulated utility. The text was not a universal instruction for every municipal, governmental or cooperative provider in Oklahoma.

Identify the provider named on the electric bill. Request its written classification of the exact system, including panel DC rating, continuous inverter AC output, connection method, anti-islanding evidence and expected export. Do not borrow PSO or OG&E instructions for a different provider unless that provider adopts them.

How the current interconnection and meter route works

The OCC's current net-metering page says grid-connected distributed generation is governed by 17 O.S. section 156 and OAC 165:40:9. Its guidance covers qualified rated capacity of 300 kW or less and uses a 125% peak-load limit. Those are general distributed-generation rules, not a plug-in socket exemption.

Provider implementation still controls the project sequence. PSO tells customers to submit an interconnection application before connecting a distributed energy resource. Its current process includes technical review, approval, installation, inspection and an interconnection agreement. The technical page also calls for IEEE 1547-2018-certified equipment and a visible lockable disconnect. These are PSO instructions, not a statewide checklist for every provider.

Ask for the current application, tariff, equipment list, one-line diagram requirements, inspection steps, meter work and permission-to-operate condition before ordering. If the provider says an ordinary application does not fit a small plug-in device, request that answer in writing rather than assuming the ended bill supplies an exemption.

HB 4060 did not name UL 3700 or an NRTL

The safety clause required compliance with nationally recognized electrical safety standards and anti-islanding protection. It did not name UL 3700, UL 1741, IEEE 1547 or the National Electrical Code. Nor did it require certification by a nationally recognized testing laboratory. Do not read those requirements into the former bill.

UL 3700 is the December 11, 2025 Outline of Investigation for Interactive Plug-In PV Equipment and Systems. It is relevant evidence for this product category, but HB 4060 did not make it a statutory condition. A component listing under another standard also would not prove that the complete panel, inverter, cable, plug and protection package met every proposed definition and safety condition.

Verify the exact model and configuration in the certifier's public directory, including the named standard and any installation conditions. OSHA recognition applies only within each NRTL's approved scope. The scope record helps evaluate product evidence, but it does not revive or rewrite HB 4060.

• Record the exact panel, inverter, cable, plug and protection model numbers.
• Match certification records to the supplied configuration, not a related component or product family.
• Confirm the named test standard and the laboratory's approved scope.
• Keep product evidence separate from utility approval and property permission.

Export value, electrical work and property permission remain separate

HB 4060 expressly denied any new right to compensation for exported electricity and left existing distributed-generation and net-metering programs unchanged. The OCC currently describes retail netting up to onsite consumption and utility purchase or credit of excess generation at avoided energy cost for covered net-metering customers. That does not establish how an unapproved plug-in configuration would be measured or credited.

Model savings from direct daytime use until the provider confirms the applicable tariff and meter in writing. A meter capable of recording reverse flow does not by itself create a credit. The proposed bill's primary-use language focused on offsetting consumption, not earning export revenue.

Oklahoma adopted the 2023 National Electrical Code effective September 14, 2024. The Construction Industries Board says notice can be required for electrical work in places without an adopted code, permit requirement or appointed inspector. Local enforcement and provider requirements can add address-specific steps, so confirm the circuit, receptacle, protection, permit and inspection path for the actual site.

The ended bill created no landlord, association or structural right. Obtain a written property decision for the exact panel position, mount, support, cable route, outlet and removal plan. Electrical eligibility, if established through today's route, would still not prove that a balcony or facade may be used.
