Xcel Energy customers with solar in Minnesota receive net metering credits at the full retail rate under Minnesota PUC net metering rules (Minn. Stat. §216B.164). Credits carry forward month-to-month on the annual billing period. Minnesota Solar*Rewards provides additional per-kWh performance payments for 10 years on top of net metering savings — this is a major financial differentiator for Minneapolis solar. Cold-climate note: Minneapolis solar production is more skewed toward summer than southern cities; winter production is real but significantly lower due to shorter days and potential snow coverage.

How it works
How solar savings work in Minneapolis
- Your panels produce power year-round in Minneapolis — with a cold-climate twist Minneapolis averages 4.80 peak sun hours per day — better than many expect for a northern city. Minnesota's clear, dry air means summer days produce excellent solar output. A 6 kW system produces roughly 7,208 kWh/year, peaking strongly June–August. Winter production is real but significantly reduced — short days, lower sun angle, and potential snow cover mean December–January produce roughly 35% of peak summer months. Snow generally slides off modern tilted panels within 1–2 sunny days and does not permanently reduce annual output.
- Cold temperatures actually boost panel efficiency This is Minneapolis's hidden solar advantage: solar panels operate more efficiently at colder temperatures. Cold, clear March and October days can generate surprisingly high output compared to hot humid summer days in southern cities where heat-related efficiency losses reduce production. The cold-climate efficiency boost partially offsets shorter winter daylight.
- An inverter converts DC to AC A string inverter or microinverters convert DC electricity from the panels to AC power your home uses. Modern inverters achieve 96–99% conversion efficiency.
- You use solar power instead of buying from Xcel Energy Every kWh your system produces offsets what you buy from Xcel at approximately $0.135/kWh. A 6 kW system in Minneapolis produces ~7,208 kWh/year — saving approximately $973/year at current Xcel rates.
- Excess power flows back to Xcel at retail rate via net metering Under Minnesota PUC net metering rules, excess solar exported to the Xcel grid is credited at the full retail rate against your monthly bill. Credits carry forward month-to-month throughout the annual period, helping balance winter shortfalls with summer surpluses.
- Solar*Rewards pays you monthly for 10 years — the major differentiator Minnesota Solar*Rewards is the standout financial incentive for Minneapolis solar. Xcel pays approximately $0.07/kWh for every kWh your system generates, for 10 years. For a 6 kW Minneapolis system producing ~7,208 kWh/year: $0.07 × 7,208 = $505/year × 10 years = ~$5,040 total incentive income. This income arrives as monthly bill credits on top of net metering savings, dramatically improving payback from ~13 years (energy savings only) to ~8.3 years.
- You claim the 30% federal ITC in the installation year Claim a 30% federal Investment Tax Credit on the full installed cost ($5,220 on a $17,400 system) in the tax year you install. Combined with Solar*Rewards income and net metering savings, Minneapolis solar can offer 8–9 year payback for many homeowners. Also apply for the Minnesota property tax exemption with Hennepin County to save ~$209/year for the system's lifetime.
FAQ
Common solar savings questions for Minneapolis, MN
How much can I save with solar in Minneapolis, MN?
A 6 kW system in Minneapolis produces roughly 7,208 kWh/year and saves approximately $973/year in Xcel Energy electricity costs. After the 30% federal ITC ($5,220), net system cost is about $12,180. Xcel Solar*Rewards adds approximately $505/year for 10 years (~$5,040 total), cutting effective payback to approximately 8.3 years. Over 25 years, combined savings can reach $26,000+, with the first decade boosted by Solar*Rewards income.
What is Minnesota Solar*Rewards and how does it work?
Minnesota Solar*Rewards is Xcel Energy's performance-based solar incentive program, administered under the Minnesota Solar Energy Standard. Approved residential customers receive a monthly payment for every kWh their system generates for 10 years. The current standard incentive rate for Xcel residential systems is approximately $0.07/kWh as of 2026 — meaning a 6 kW Minneapolis system generating ~7,208 kWh/year earns ~$505/year in additional income for a decade. Incentive rates decline as program capacity fills, and waitlists are possible. Verify current rates and availability at xcelenergy.com/solarrewards before committing to a system.
Does Minneapolis get enough sun for solar to make financial sense?
Yes — especially with Solar*Rewards. Minneapolis's 4.80 peak sun hours/day is better than many expect for a northern city. Minnesota's clear, dry climate produces good solar output despite cold winters. When Solar*Rewards ($505/year for 10 years) is combined with Xcel net metering and the federal ITC, Minneapolis solar can achieve payback of approximately 8–9 years — making it financially comparable to much sunnier locations.
How does cold weather and snow affect Minneapolis solar panels?
Two effects work in opposite directions. Cold temperatures boost panel efficiency — panels actually generate more electricity per unit of sunlight at 32°F than at 95°F. This is a genuine advantage for Minneapolis. Snow accumulation temporarily reduces output but typically slides off modern tilted panels within 1–2 sunny days. Heavy snow cover is accounted for in the production estimates above. The net cold-climate effect is modest: winter months produce less due to shorter days and lower sun angles, but the efficiency boost partially compensates.
Does Minnesota have net metering?
Yes. Minnesota requires retail-rate net metering for residential solar under Minn. Stat. §216B.164. Xcel Energy credits excess solar at the full retail rate (~$0.135/kWh) against your monthly bill. Credits carry forward month-to-month; any unused credits at the end of the annual period are paid at the avoided cost rate. This allows Minneapolis solar owners to bank summer surplus production against winter deficit months.
How many solar panels does a Minneapolis home need?
A typical Minneapolis home using 600–800 kWh/month needs a 6–8 kW system — roughly 16–21 standard panels at 380–400 W each. Minneapolis's good solar resource and Xcel's net metering mean the system can effectively bank summer production against winter shortfalls. Use the calculator above with your monthly Xcel bill to estimate accurately.
