Minnesota Net Metering — Full 1:1 Retail Rate, Up to 40 kW

Minnesota state law (Minn. Stat. § 216B.164) requires regulated utilities to offer full retail-rate net metering for residential systems up to 40 kW AC — one of the most generous caps in the country. The mechanics:

• •Full retail credit: Every kWh your system exports to the grid earns a credit equal to the full retail rate you pay for electricity — no discounted avoided-cost rate, no tiered reduction.
• •Monthly rollover: Unused credits carry forward month to month, letting summer production bank credits that offset winter bills.
• •40 kW system cap: Covers virtually all residential rooftop installations many times over — the typical Minnesota home system is 8–12 kW.
• •Applies to investor-owned utilities: Xcel Energy, Minnesota Power, Otter Tail Power, and other utilities regulated by the Minnesota Public Utilities Commission are required to comply. Municipal utilities and rural electric cooperatives may have different policies — confirm directly with your provider if you are not served by an investor-owned utility.

Xcel Energy Solar*Rewards Program

Xcel Energy customers in Minnesota can access Solar*Rewards, a performance-based incentive that pays on top of standard net metering:

• •Payment rate: Approximately $0.03 per kWh your system generates, paid annually each February for 10 years.
• •Eligible system size: 0.5 kW to 20 kW DC — covers the vast majority of residential rooftop installations.
• •Income-qualified bonus: Participants meeting income-qualification thresholds may be eligible for a larger upfront incentive of approximately $3.00/kWh. Verify current income qualification criteria directly with Xcel.
• •Annual funding limits — first-come-first-served: Solar*Rewards is funded each program year and enrollment can close once capacity is reached. Availability, payment rates, and program terms are subject to change by Xcel and the Minnesota PUC. Confirm current enrollment status and incentive rates directly with Xcel Energy at xcelenergy.com before factoring this into your budget.

Solar*Rewards is available only to Xcel Energy customers. Minnesota Power, Otter Tail Power, municipal utility, and co-op customers should check with their own provider about available performance incentive programs.

Community Solar Garden Program — No Roof Required

Minnesota's LMI-Accessible Community Solar Garden Program (which replaced the legacy program on January 1, 2024) is one of the most developed community solar programs in the country. It lets renters, condo owners, and homeowners whose roofs aren't suitable for solar subscribe to a share of a shared off-site solar garden and receive monthly bill credits.

• •No installation required: Subscribe to a share — no panels on your roof, no upfront equipment cost.
• •Typical savings: Subscribers generally save an estimated 5–10% on their electricity bills through monthly bill credits. Actual savings depend on subscription size, solar garden output, and current electricity rates.
• •25-year transferable subscriptions: Subscriptions run for 25 years and can be transferred to a new address if you move within Xcel's service territory.
• •Enrollment cap: Annual program capacity is approximately 100 MW for the 2024–2026 period. The program primarily operates in Xcel Energy's service territory.

Check current community solar garden availability and subscription openings at xcelenergy.com or through the Minnesota Department of Commerce (mn.gov/commerce).

Minnesota Electricity Rates and Solar Resource

Minnesota's average residential electricity rate is roughly 15–16.4 cents/kWh — below the national average of approximately 18.8 cents/kWh as of 2026. Lower rates than high-cost states extend payback periods somewhat, but the strong 1:1 net metering and Solar*Rewards incentive (Xcel customers) partially offset this difference. All rate figures are approximate and vary by utility and rate class — confirm your current rate on your electricity bill or directly with your utility.

Minnesota averages roughly 4.0–4.5 peak sun hours per day on an annual basis, with seasonal variation from approximately 5.4 hours/day in summer to around 3.5 hours/day in winter. This is below the national sunbelt average, but two factors help. First, Minnesota's 1:1 net metering lets you bank summer surplus credits to offset winter bills — effectively smoothing the seasonal imbalance. Second, solar panels operate more efficiently in cold temperatures than in heat, partially offsetting reduced winter sunlight. Treat these as approximate regional averages; actual production at your address depends on roof orientation, pitch, shading, and local microclimate. Your installer can provide a site-specific estimate using NREL's PVWatts or similar tools.
