Minneapolis Solar Overview
Minneapolis may seem like an unlikely solar market—cold winters, shorter days, and plenty of snow. But the Twin Cities have become one of the Midwest's strongest solar markets, thanks to excellent state incentives, Xcel Energy's Solar*Rewards program, and surprisingly good solar production during the long summer days.
Xcel Energy Programs
Solar*Rewards Program
Xcel Energy's Solar*Rewards is one of the better utility solar programs in the country. Here's how it works:
- Performance-based incentive: Payment based on actual production
- 10-year contract: Locked-in incentive rates for a decade
- Net metering: Full retail credit for excess generation
- No system size cap: Residential systems of any reasonable size qualify
Net Metering Details
| Feature | Xcel Energy Policy |
|---|---|
| Credit Rate | Full retail rate (~$0.14/kWh) |
| Credit Rollover | Monthly, annual true-up |
| System Size Limit | 40 kW residential |
| Interconnection | Straightforward process |
Minnesota Solar Incentives

Costs & Savings in Minneapolis
Typical System Costs
| System Size | Gross Cost | After MN Incentives* |
|---|---|---|
| 5 kW | $15,000 | $12,000-13,000 |
| 7 kW | $21,000 | $17,000-18,500 |
| 10 kW | $30,000 | $24,000-26,000 |
*Includes Solar*Rewards present value; excludes expired federal 25D credit
Savings Estimates
- Annual production: ~1,200 kWh per kW installed
- Annual savings: $150-180 per kW (at current rates)
- Payback period: 10-13 years
- 25-year savings: $15,000-25,000
Cold Climate Considerations
Winter Performance
Yes, Minneapolis gets cold and snowy. Here's the reality:
- Snow: Panels typically self-clear within 1-2 days due to angle and dark surface
- Cold temperatures: Panels are actually MORE efficient in cold (less heat loss)
- Short winter days: Production drops significantly Dec-Feb
- Long summer days: 15+ hours of daylight in June compensates for winter
Monthly Production Pattern
Expect about 60-70% of annual production from April through September. Winter months (Nov-Feb) contribute only about 15% of annual production. This is normal and factored into savings calculations.
Installation Considerations
- Roof pitch: Steeper pitches (30-40°) help snow slide off faster
- Snow guards: May be needed to prevent dangerous snow slides
- Racking: Must handle snow load requirements
- Installation timing: Spring/summer/fall preferred for installation
The Bottom Line
Minneapolis is a solid solar market despite its northern location.Xcel Energy's Solar*Rewards program, Minnesota's tax exemptions, and full retail net metering create favorable economics. Payback periods of 10-13 years are typical, with strong long-term savings potential.
Best candidates: Homeowners with south-facing roofs, electric bills over $100/month, and plans to stay in their home 10+ years. The combination of moderate electricity rates and strong incentives makes ownership (cash or loan) competitive with PPA/lease options.
