Minnesota Plug-In Solar Laws
By Daniel Okafor · Last reviewed In short: Minnesota has not enacted a statewide plug-in solar exemption. HF 3555 and companion SF 3873 remain in their first committees, so the proposed 1,200 W route is not current law. Minnesota PUC guidance still directs customers to get local utility approval before installing solar. Check the exact utility, electrical, property and local requirements before connection.

What this means today
Minnesota's companion bills have not advanced beyond their first committee referrals. HF 3555 was introduced in the House and referred to Energy Finance and Policy on February 23, 2026. SF 3873 was introduced in the Senate and referred to Energy, Utilities, Environment, and Climate on February 26. The official records show no committee passage, floor vote or enactment.
The proposals would create a narrow exemption for a defined plug-in solar photovoltaic device, but they do not change today's rules. Minnesota Public Utilities Commission guidance says customers must gain approval from the local utility before installing solar and must apply for permission to operate distributed energy resources in parallel with the grid. Municipal and cooperative customers should still ask their own utility for its applicable process.
What applies today versus what HF 3555 and SF 3873 propose
| Question | What applies today | What the companion bills propose |
|---|---|---|
| Legal status | No enacted statewide plug-in-specific exemption appears in the reviewed official record. | A narrow exemption would begin only if a bill completes the Legislature and is finally enacted. |
| Output threshold | No statewide plug-in-specific 1,200 W exemption is in force. | A qualifying device would have a maximum power output of 1,200 W. |
| Utility process | Obtain the serving utility's approval before installing grid-parallel solar under current PUC guidance. | A qualifying device would be exempt from an interconnection agreement and utility approval, fees, conditions and reporting. |
| Product evidence | Current utility, electrical-code and equipment requirements control. | Interactive plug-in PV equipment and systems would need an applicable listing or certification from an OSHA-recognized NRTL. |
| Net metering and export | Use the approved utility route and tariff to determine metering and compensation. | The device would be exempt from Minnesota's net-metering provisions; the bills do not create export compensation. |
| Electrical and local rules | The customer remains responsible for state and local electrical, building and zoning compliance. | The proposed utility exemptions do not state that electrical, building, fire, structural or local requirements disappear. |
| Property permission | Lease, association, balcony, facade and mounting decisions remain separate. | The companion bills do not grant a renter or association member permission to alter or use the property. |
What HF 3555 / SF 3873 says
HF 3555 and SF 3873 use the same introduced text. A plug-in solar photovoltaic device would primarily offset part of a customer's electricity consumption, have a maximum power output of 1,200 W, be capable of connection with onsite energy storage, and be listed or certified for interactive plug-in photovoltaic equipment and systems by a laboratory recognized under federal OSHA's NRTL program. A qualifying device would be exempt from an interconnection agreement, Minnesota net-metering provisions, and utility-imposed fees, conditions, approval or reporting for installation or operation. The utility would not be liable for damage or injury caused by the device. The section would take effect the day following final enactment.

The current route still starts with utility approval
Minnesota PUC guidance says a customer must gain local utility approval before installing solar. A grid-parallel distributed energy resource goes through an interconnection application and a contract. Depending on the system and utility, that may be the Uniform Statewide Contract or the Minnesota Interconnection Agreement.
The PUC-approved statewide process applies to investor-owned utilities. Municipal and cooperative utilities use their own procedures, so customers should ask their serving utility to classify the exact socket-connected, grid-parallel configuration. Provide the model, maximum output, plug and circuit method, anti-islanding evidence, mounting location and proposed export behavior. Keep the written response tied to the service address.
What the 1,200 W proposal does and does not define
The introduced text sets a maximum power output of 1,200 W. It does not say whether that figure means panel DC nameplate capacity, continuous inverter AC output or maximum power sent to the grid. Those measurements can differ, so record each one and wait for any final text or implementation guidance before deciding whether a configuration fits the threshold.
The proposal also says the device must be capable of connection with an onsite energy storage system. That condition does not turn the grid-tied device into backup power. Ordinary interactive solar must stop energizing the grid during an outage unless a separate, approved isolation and backup architecture establishes a safe local supply.
The bills do not name UL 3700
HF 3555 and SF 3873 do not mention UL 3700 or UL 1741 by number. They require listing or certification for interactive plug-in photovoltaic equipment and systems by a laboratory recognized under the federal Occupational Safety and Health Administration's Nationally Recognized Testing Laboratory program.
The requirement covers the interactive plug-in equipment and system, not merely one component. A UL 1741 listing for an inverter does not by itself prove that the assembled panels, inverter, controls, cable, plug and instructions meet the proposed Minnesota definition. UL 3700 is an Outline of Investigation, and any claimed complete-system evidence should be matched to the exact model and configuration in a public testing-laboratory record.
- Match the exact system model and included components to the NRTL record.
- Separate panel DC watts, inverter continuous AC output and any export limit.
- Verify outage behavior, plug, cable, circuit protection and installation instructions.
- Do not infer future eligibility from a retailer's Minnesota shipping availability.
Minnesota's electrical-code transition needs a dated check
Minnesota Department of Labor and Industry says electrical permits filed before August 17, 2026 must comply with the 2023 National Electrical Code. Permits filed on or after August 17 use the 2026 NEC. The filing date therefore determines the adopted code edition when a permit is required, but it does not decide whether a plug-in configuration is approved.
PUC guidance leaves state and local code compliance with the customer. Minnesota law also allows political subdivisions to enforce more stringent electrical requirements. Ask the electrical inspector and local building authority about the exact receptacle, branch circuit, mounting method, cable route and any required permit before treating utility approval as the only gate.
Net metering and property rights stay separate
The companion bills would exempt a qualifying device from Minnesota's net-metering provisions. They do not create an export credit. Under the current route, the approved utility tariff and meter determine what happens to surplus energy. Model savings from direct daytime self-consumption unless a written arrangement establishes compensation.
Minnesota Statute 500.216 limits some private restrictions on roof-mounted solar for specified owner-occupied dwellings. It is not blanket permission for a renter to attach panels to a balcony, railing, facade or common area. Where the statute applies, the private-entity process can include an interconnection application and at least a 60-day decision window. Renters and owners outside that scope still need a property-specific written decision for the proposed mount and cable route.
Your serving utility still matters
HF 3555 and SF 3873 are not enacted. Minnesota PUC guidance currently directs customers to obtain local utility approval before installing grid-parallel solar and to follow the serving utility's interconnection process.
Pre-purchase checklist
- 1Open the official HF 3555 and SF 3873 status pages and confirm whether either bill has moved beyond committee referral.
- 2Identify the serving utility and request its current application, contract, meter and permission-to-operate process for the exact grid-parallel configuration.
- 3Record panel DC nameplate capacity, every inverter's continuous AC output and any maximum grid-directed output separately.
- 4Match the exact complete system to an OSHA-recognized NRTL record rather than relying on a component mark or retailer claim.
- 5Verify outage behavior, plug, cable, receptacle, branch circuit, protection method and manufacturer instructions.
- 6Confirm whether the 2023 or 2026 NEC applies to any required permit, then ask the electrical and local building authorities about additional requirements.
- 7Obtain written landlord, association or other property approval for the exact panel, mount and cable route.
- 8Confirm meter behavior and model savings from self-consumption unless an approved tariff documents export compensation.
- 9Do not connect under the proposed exemption unless a final bill is enacted and in force.

Frequently asked questions
Is plug-in solar legal in Minnesota right now?
Minnesota has no enacted statewide plug-in-specific exemption in the reviewed official record. HF 3555 and SF 3873 remain in committee. That does not prove every configuration is prohibited. It means the proposals cannot be used as permission, and current PUC guidance directs customers to obtain local utility approval before installing grid-parallel solar.
Did Minnesota HF 3555 or SF 3873 pass?
No. HF 3555 was introduced and referred to House Energy Finance and Policy on February 23, 2026. SF 3873 was introduced and referred to Senate Energy, Utilities, Environment, and Climate on February 26. The official records show no committee passage, chamber passage or enactment at the August 12 review.
Is the proposed 1,200 W limit based on panel wattage?
The introduced text says maximum power output of 1,200 W but does not label it panel DC nameplate capacity, continuous inverter AC output or grid-export output. Keep those measurements separate. Any final enacted text or implementation guidance would control how the threshold is applied.
Would a Minnesota plug-in system need utility approval?
Today, Minnesota PUC guidance says customers must gain approval from the local utility before installing solar and apply for permission for grid-parallel operation. HF 3555 and SF 3873 would exempt a qualifying device from an interconnection agreement and utility approval, fees, conditions and reporting, but those proposed exemptions are not law.
Would Minnesota require UL 3700 certification?
The companion bills do not name UL 3700 or UL 1741. They require listing or certification for interactive plug-in photovoltaic equipment and systems by an OSHA-recognized NRTL. Verify the exact complete-system record. A UL 1741 inverter listing alone would not prove that the assembled configuration meets the proposed definition.
Would Minnesota pay for exported plug-in solar power?
The proposals would exempt qualifying devices from Minnesota's net-metering provisions and do not create an export-payment right. Under the current route, the approved utility tariff and meter determine compensation. Base savings on direct self-consumption unless the serving utility documents a credit for the exact arrangement.
Would the bills give Minnesota renters permission to install panels?
No. HF 3555 and SF 3873 address utility requirements, not a tenant's right to use a balcony, railing, facade or common area. Minnesota Statute 500.216 concerns specified owner-occupied, roof-mounted systems and is not blanket renter permission. Obtain a property-specific written decision for the mount and cable route.
