Minnesota is one of the few states left where every utility, investor-owned or not, has to credit your solar output at essentially the retail energy rate. That is a genuinely good position. There is a bill in the legislature that would end it for some Minnesotans and not others, it has not been enacted, and whether it should change your timing depends entirely on who sends your bill.
One Rule, Every Utility, Which Is Rare
Minnesota Statutes 216B.164 subdivision 3 requires net metering for systems under 40 kW at all utilities: investor-owned, cooperative and municipal alike. Compensation is at the average retail utility energy rate, which works out as one-to-one on the energy portion of your bill, with monthly netting and payout. Xcel, the largest provider here, credits at one-to-one retail.

Most states’ net metering laws bind the investor-owned utilities and leave cooperatives and municipals to their own terms, which is why South Dakota’s answer collapses to “ask your provider” and Kansas’s statute reaches only the investor-owned utilities. Minnesota does not have that gap, and it is worth knowing you are covered.
| Provision under 216B.164 | What it means for a homeowner |
|---|---|
| Applies to systems under 40 kW | Far above what any house needs, so not a real constraint |
| Covers investor-owned, cooperative and municipal utilities | No coverage gap, unlike most states |
| Compensation at the average retail energy rate | Your output is worth roughly what your power costs |
| Or you may elect avoided cost instead, under subdivision 4 | An option almost nobody should take, but it exists |
| Cooperatives and municipals may add a cost-recovery fee | A real cost that does not appear in the statute’s headline |

The Pending Bill Splits Minnesota in Two
Senate File 4504, the energy omnibus bill, would end net metering for new cooperative and municipal systems that apply to interconnect after December 31, 2026, moving them to avoided cost. It passed the Senate 35 to 32 on May 12, 2026 and was referred to the House Energy Finance and Policy Committee the same day. As of August 20, 2026 it has not passed the House and has not been signed; it is a bill, not a law. Investor-owned territories would be unaffected and existing systems would be grandfathered.
It is not law, and bills change or die routinely. What follows is how to think about it, not a prediction that it passes.
If an investor-owned utility bills you, this proposal does not reach you and there is no timing argument at all. Decide on the merits, at whatever pace suits you.
If a cooperative or municipal utility bills you, the question is asymmetry. Applying while current rules hold costs nothing if the bill dies, because you keep the same arrangement either way. Waiting costs something only if it passes. That is a mild reason to bring a decision forward if you were already close to making it, and a poor reason to make a decision you were not ready for.
What the Numbers Actually Look Like
A typical Minnesota system is 6.12 kW at about $19,033, producing roughly 8,550 kWh a year against household consumption of around 712 kWh a month, well below what most states use. Minnesotans use less electricity than most, partly because heating here is usually not electric.
Because output is credited at your utility’s average retail energy rate, which runs about 15.14¢ on the statewide average, essentially all of that production counts, giving $1,294 a year and a simple payback of about 14.7 years. Minnesota needs one figure rather than a range, because one-to-one crediting means how much you personally use during daylight barely changes the outcome. A cooperative cost-recovery fee, where one applies, would lengthen it: at $10 a month, year-one savings fall to about $1,174 and simple payback stretches to about 16.2 years.
Xcel customers who secure Solar*Rewards add about $256 a year for ten years on this system, which shortens the payback by roughly two years; the figure above excludes it because funding is not guaranteed.
Two things hold that figure back from being better. Minnesota installations run about $3.11 per watt at the state benchmark as of March 1, 2026, on the expensive side, and 4.84 peak sun hours is modest. What rescues it is a 15.14¢ retail rate rising about 3.45% a year, and the fact that one-to-one crediting means none of the output is discounted.
The Cooperative Small Print Worth Reading
Two provisions apply specifically to cooperative and municipal customers and neither is obvious from the headline rule.
- A cost-recovery fee may be added. The statute permits it, so ask what yours is in dollars per month before you model anything. On a payback near fifteen years, a modest monthly fee moves the answer by a year or more.
- Customers may elect kilowatt-hour credits that cancel at year-end. That option can suit a household whose production and consumption line up across the year, and it quietly forfeits value for one whose surplus builds up. Ask which basis your account uses and whether you get a choice.
- The subdivision 4 avoided-cost election exists. It is worth knowing only so you can decline it. Nobody with normal household consumption should choose avoided cost over the retail energy rate.
When to Leave It in Minnesota
- If you expect to move inside fifteen years. With so little spread around the central figure, time in the house is the main variable you control and the one that most often decides against.
- If the roof carries snow for long stretches or is shaded. At 4.84 peak sun hours there is not much margin to give away.
- If a quote shows a 30% federal credit. Section 25D is $0 for purchased systems whose installation is completed after December 31, 2025 under Public Law 119-21, and the figure on this page already assumes no credit at all. No company currently offers a lease or PPA in Minnesota, so the separate Section 48E business credit that a third-party owner can claim does not reach a Minnesota homeowner in practice.
- If an installer is using the pending bill to create urgency without first establishing whether your utility is even covered by it. For most Minnesotans it is not.
- If you are on a cooperative and cannot get the fee in writing. It is a recurring cost against a fifteen-year payback.

Minnesota Solar FAQs
Yes for a household staying put, at a simple payback of about 14.7 years on a typical 6.12 kW system costing around $19,033, assuming no tax credit. Minnesota credits output at essentially the retail energy rate under Minnesota Statutes 216B.164, so nearly all production counts at the full 15.14¢. Installations are on the expensive side at about $3.11 per watt and sunshine is modest at 4.84 peak hours, which is what keeps the figure in the mid-teens.
Not currently, and any answer that says otherwise is ahead of the facts. Senate File 4504, the energy omnibus bill, would end net metering for new cooperative and municipal systems that apply to interconnect after December 31, 2026, moving them to avoided cost, with investor-owned territories unaffected and existing systems grandfathered. It passed the Senate 35 to 32 on May 12, 2026 and was referred to the House Energy Finance and Policy Committee the same day. As of August 20, 2026 it has not passed the House and has not been signed; it is a bill, not a law.
Only if a cooperative or municipal utility bills you. If you are served by an investor-owned utility such as Xcel, the proposal does not reach you and there is no timing argument at all. If you are on a cooperative or municipal system, the framing is asymmetry: applying while current rules hold costs nothing if the bill dies, and waiting costs something only if it passes.
They are permitted to. Minnesota Statutes 216B.164 allows cooperative and municipal utilities to add a cost-recovery fee, so ask what yours is in dollars per month before modeling anything. Against a payback near fifteen years, a modest monthly fee moves the answer by a year or more. Cooperative customers may also elect kilowatt-hour credits that cancel at year-end, which suits some consumption patterns and quietly forfeits value in others.
Yes, and that is unusual. Minnesota Statutes 216B.164 subdivision 3 requires net metering for systems under 40 kW at all utilities, investor-owned, cooperative and municipal alike. Most states’ net metering laws bind the investor-owned utilities and leave cooperatives and municipals to their own terms, which is why South Dakota’s answer collapses to asking your provider and Kansas’s statute reaches only the investor-owned utilities. Minnesota has no such coverage gap.
Methodology: $3.11 per watt as of March 1, 2026, no federal residential credit for host-owned systems, retail-rate compensation under 216B.164; the 14.7-year figure is simple payback before financing, escalation (the state 5-year average is 3.45%) and degradation.
