Is plug-in solar legal in Minnesota?
- Introduced
- Passed one chamber
- Passed both chambers
- Signed
- In effect
What this means for you
✓ What you can do
- Apply for interconnection like any small generator (Certified inverter <=20 kW), typical fee $200.
- Use portable panels with a power station, never connected to house wiring, with no permission at all.
- Install conventional rooftop or ground-mount solar through the standard interconnection process.
✕ Not yet / not allowed
- Plug a grid-tied kit into an outlet without an interconnection agreement; it can breach your service terms.
- Expect a permit or wiring exemption; none exists without a law.
- Count on SF 3873 / HF 3555; folded into SF 4504 omnibus this year: SF 4504 passed Senate 5/12/2026; House never acted; sine die 5/18/2026; deferred to 2027.
What the rules say
Minnesota's 2026 bills did not pass; Xcel interconnection rules apply.
Before you plug in: Minnesota checklist
- The rule that applies is Minnesota Public Utilities Commission's interconnection process: MN DIP (2019) Simplified Process.
- A plug-in kit falls in the smallest tier (Certified inverter <=20 kW). Xcel $200 cost-share fee (<=40 kW); munis $100-$125.
- Permits: Licensed electrician or homeowner with permit/inspection; 2026 NEC.
- Only consider kits with a UL 1741-listed inverter (UL 3700 preferred); a non-listed inverter will not be approved anywhere.
- What exports are worth: Retail-rate net metering <40 kW (Minn. Stat. 216B.164).
- If approval is slow or costly, a portable panel and power station (never connected to house wiring) needs no permission.
- Watch SF 3873 / HF 3555; folded into SF 4504 omnibus: SF 4504 passed Senate 5/12/2026; House never acted; sine die 5/18/2026; deferred to 2027.
The rules in detail
Minnesota has no statute specific to plug-in solar (the only bill so far is HF 3555 / SF 3873 / SF 4504). Average residential electricity price: 17.45¢ per kWh (EIA, July 2026).
- Sponsor: Rep. Larry Kraft (HF 3555); Sen. Rob Kupec (SF 3873).
