Michigan's solar math in 2026 is honest work, not a slam dunk. The state's 4.0 peak sun hours per day are real but modest, and electricity rates from DTE Energy and Consumers Energy average $0.192/kWh — among the higher rates in the Midwest, which helps the ROI considerably. There's no Michigan state income tax credit for solar, but full retail net metering is in place statewide.

Key Takeaways
- A typical 8 kW Michigan system costs ~$22,400 at $2.80/watt (LBNL 2024) — no federal 25D credit applies in 2026
- Michigan electricity rates of $0.192/kWh (EIA 2025) are above the national average, improving solar ROI despite modest sun
- Full retail net metering is available statewide for DTE and Consumers Energy customers
- Estimated payback: 11–15 years — viable over a 25-year panel lifespan but requires a longer-term commitment
Michigan Solar Costs in 2026
At $2.80/watt, Michigan is near the national median for installation costs. An 8 kW system — appropriate for a typical Michigan home — costs approximately $22,400 before any incentives. With 4.0 peak sun hours per day averaged across the state, that system produces roughly 11,700 kWh annually.
What partially offsets the lower sun production is Michigan's above-average electricity rate. At $0.192/kWh, Michigan homeowners pay significantly more per kWh than the national average ($0.161/kWh), which means each kWh of solar production saves more.
| System Size | Cost at $2.80/W | Annual Production (4.0 hrs) | Annual Savings at $0.192/kWh |
|---|---|---|---|
| 6 kW | $16,800 | ~8,760 kWh | ~$1,682 |
| 8 kW | $22,400 | ~11,680 kWh | ~$2,242 |
| 10 kW | $28,000 | ~14,600 kWh | ~$2,803 |
Those savings assume full self-consumption. Michigan's full retail net metering means exported kWh earn the same $0.192/kWh credit, so the figure holds whether you're home during solar hours or not.
Net Metering in Michigan: The Full Retail Policy
Michigan's net metering law — updated under Public Act 235 of 2023 — requires DTE Energy, Consumers Energy, and other investor-owned utilities to credit residential solar exports at the full retail rate. This is a meaningful policy advantage compared to states like California (NEM 3.0) or Arizona, where exports earn only $0.05–$0.09/kWh.
For Michigan solar owners, this means:
- You can size your system to cover 100% of your annual consumption without penalizing exported power
- Excess summer production credits offset winter grid purchases at the same rate
- The annual true-up calculation is straightforward: your net consumption times the retail rate
Michigan cooperative and municipal utilities are not covered by the statewide net metering rules — check with your specific utility if you're outside DTE or Consumers Energy territory.
Why Michigan Has No State Solar Credit
Michigan has no state income tax credit specifically for solar installations. Unlike states such as New York (25% credit, $5,000 cap) or Arizona (25% credit, $1,000 cap), Michigan relies entirely on the federal incentive structure — and with Section 25D expired as of December 31, 2025, Michigan homeowners in 2026 have no state or federal income tax credit to apply.
The practical implication: the full $22,400 (for an 8 kW system) is the net cost in Michigan. No credits reduce the upfront figure. This is the main reason Michigan's payback period runs 11–15 years rather than the 7–10 years seen in higher-credit or higher-rate states.
According to Lawrence Berkeley National Laboratory's Tracking the Sun 2024 report, states without incentive programs show payback periods 30–50% longer than comparable states with active state credits, holding sun resource and electricity rates constant.
Regional Variation: Southern Michigan vs. the U.P.
Michigan's solar resource varies meaningfully by geography. Southern Michigan (Detroit, Ann Arbor, Grand Rapids, Kalamazoo) averages 4.0–4.3 peak sun hours per day — toward the better end of the state. The Upper Peninsula averages 3.5–3.8 peak sun hours, producing meaningfully less solar energy for the same system size.
| Region | Peak Sun Hours/Day | 8 kW Annual Production | Annual Savings ($0.192/kWh) |
|---|---|---|---|
| Detroit / Ann Arbor | ~4.2 | ~12,300 kWh | ~$2,362 |
| Grand Rapids | ~3.9 | ~11,400 kWh | ~$2,189 |
| Upper Peninsula | ~3.6 | ~10,500 kWh | ~$2,016 |
What to Do Next
Confirm your utility and rate tier.
DTE Energy and Consumers Energy both offer full retail net metering, but their rate structures differ. Your actual per-kWh rate — including any tiered or TOU pricing — determines your real annual savings. Check your last electricity bill.
Assess your time horizon honestly.
Michigan’s 11–15 year payback requires confidence you’ll stay in your home through the payback period. Solar can still make sense on a 25-year panel lifespan, but it’s worth honest reflection before committing $22,000+.
Run your personalized ROI estimate.
Your ZIP code determines your actual sun hours, and your annual kWh usage determines optimal system size. The statewide averages shift based on your specific roof and location.
Get at least three competing installer quotes.
Michigan’s installer market is active in southern Michigan, thinner in the U.P. EnergySage and SolarReviews can help identify vetted installers in your area and typically save buyers 15–20% on average.

Bottom Line
Michigan solar in 2026 works — but it requires patience. The combination of 4.0 peak sun hours and no state or federal credit stretches payback to 11–15 years. The high electricity rate ($0.192/kWh) and full retail net metering are the most favorable factors. For homeowners planning to stay in their home for 15+ years, the 25-year panel lifespan still delivers a positive return. For those with shorter horizons, the case is harder to make.
