Everything you need to know about going solar in Michigan (MI) — costs, savings, incentives, and the best equipment for your climate.
Federal Residential Solar Tax Credit Repealed
The 30% residential solar tax credit (Section 25D) was repealed in early 2026. Homeowners who installed solar before the repeal can still claim the credit. Commercial projects retain the 30% ITC under Section 48/48E. Solar can still pay for itself through electricity savings alone.

Solar Irradiance in Michigan (2026)
Michigan receives an average of 3.5 peak sun hours per day annually, equivalent to roughly 1278 kWh/m² per year of global horizontal irradiance (GHI). Summer peaks reach about 4.5 h/day, while winter lows drop to around 2.1 h/day.
This places Michigan in the fair solar irradiance band compared with other US states. At 3.5 kWh/m²/day, each 1 kW of rooftop solar in Michigan generates approximately 996 kWh/year (assuming 78% system performance after inverter, soiling, and temperature losses), which makes an 8 kW system produce around 10,220 kWh per year.
Data source: NREL National Solar Radiation Database (NSRDB), 1998-2020 typical meteorological year averages. Michigan (MI) values reflect the statewide average; coastal, mountain, and desert microclimates can vary by ±15% from this figure.
Michigan Solar Incentives (2026)
Federal residential tax credit was repealed in early 2026. Michigan continues to offer the following state and utility-level programs:
| Incentive | Value | Eligibility | Deadline | Source |
|---|---|---|---|---|
| Federal Section 25D ITC | 0% (Repealed Q1 2026) | N/A | Was 12/31/2025 | IRS |
| Net metering (Distributed Generation tariff) | — | — | Verify with state agency | DSIRE |
| Property tax exemption | — | — | Verify with state agency | DSIRE |
| PACE financing | — | — | Verify with state agency | DSIRE |
⚠ Always verify state incentive deadlines, caps, and eligibility before signing a solar contract — programs change annually and many have annual funding caps that exhaust mid-year.
Major utility companies in Michigan
Check your utility's net metering policy, interconnection requirements, and rate structure before installing — rules vary significantly within Michigan:
- • DTE Energy
- • Consumers Energy
- • Indiana Michigan Power
- • Upper Peninsula Power
Each utility has different rate structures, net metering caps, and time-of-use schedules. Visit your utility's website for current solar interconnection requirements and queue times.

Can solar panels work efficiently in Michigan's climate?
Yes, solar panels work in all climates. Michigan's 3.5 peak sun hours/day means choosing high-efficiency panels (21%+ efficiency) is important to maximize production. Cold temperatures actually improve panel efficiency. An 8 kW system can still produce significant savings of approximately $1,329/year.
How much can I save with solar in Michigan?
An 8 kW solar system in Michigan produces approximately 10,220 kWh/year, saving about $1,329 annually. The estimated payback period is 19.9 years. Over 25 years, total savings can reach $33,225.
Does Michigan have net metering?
Net metering policies vary by utility in Michigan. Most states offer some form of net metering or net billing that credits solar homeowners for excess electricity sent back to the grid. Contact your local utility or check the DSIRE database for current Michigan net metering policies.
What is the best solar panel for Michigan?
For Michigan with 3.5 sun hours/day, high-efficiency panels are the best choice to maximize energy production. Look for panels with efficiency ratings above 21%.
What is the payback period for solar in Michigan?
The estimated payback period for an 8 kW solar system in Michigan is 19.9 years. This is calculated as: system cost ($26,400) divided by annual savings ($1,329/year). After payback, solar generates essentially free electricity for 15-20+ more years.
Do I need a battery for solar in Michigan?
A battery is not required for grid-tied solar in Michigan, but it provides backup power during outages and can increase savings with time-of-use rate optimization. Battery prices continue to decline, making storage increasingly cost-effective.
Does Michigan have solar incentives?
Michigan currently has limited state-level solar incentives, and the federal residential ITC (Section 25D) was repealed in early 2026. Solar can still pay for itself through electricity savings alone in 19.9 years.
