Michigan solar pays for the power you use, not the power you make. Exports earn a credit well below the retail price, so a typical home system takes about 17 years to pay back in our example with DTE’s credit, and about 19 with a lower co-op credit. A system sized to your own use lands sooner.
Typical payback, DTE creditAbout 17 years
DTE or Great Lakes Energy creditAbout 17 to 19 years
Typical owned 6.63 kW system at $20,487 cash (Cost Index, September 2026), exports credited at 8.709 cents per kWh (DTE) or 5.6 cents per kWh (Great Lakes Energy). We assume 60% of the power is used at home. See the math.
- Size: matched to your own use. A new system may produce up to 110% of the electricity you used in the past 12 months.
- Utility: DTE, Consumers Energy, Lansing BWL or a co-op. Each pays its own outflow credit.
- Daytime use: power used as it is made saves the full price. Exports earn the credit.
2026 rules: new home systems get no 30% federal homeowner credit (IRS). New DTE and Consumers Energy solar customers join the Distributed Generation Program, where exported power earns an outflow credit below the retail price.
How we checked this guide
Outflow credits come from the utilities’ own rate books and program pages, the electricity price from the U.S. Energy Information Administration, and the example system from the EcoGen Solar Cost Index. Where we assumed a number, the page says so.
The writer and checker shown above are EcoGen staff. EcoGen is paid when homeowners request quotes, which is explained beside the quote form. Read our editorial standards.
Michigan solar works when the power stays home
Michigan solar is worth it more often than its cloudy reputation suggests. The homes it lets down usually bought too much of it. A kilowatt-hour (kWh) is the unit your bill counts. Each kWh your home uses as the panels make it saves the full price. Each kWh sent to the grid earns only an outflow credit, your utility’s bill credit for exported power, which is well below retail. So the value lives in the panels that cover your own use. Read each row across.
System size
Worth a closer look
The design starts from your last 12 months of kWh.
Pause and check
The proposal fills the roof or matches a payment, and never asked for your usage.
Check next: the usage the installer used and the share it expects you to export.
Your utility’s credit
Worth a closer look
The quote names your utility and its outflow credit, with home use and exports on separate lines.
Pause and check
The quote credits every kWh at the full retail price.
Check next: your rate sheet’s outflow credit.
When you use power
Worth a closer look
Much of your load runs in daylight: home office, daytime laundry, a car charged at noon.
Pause and check
Evening-heavy use with no plan to shift it.
Check next: hourly data from your utility account, if you can get it.
Roof and time in home
Worth a closer look
A sound roof with years left, and you expect to stay past payback.
Pause and check
A roof under about 10 years of life, heavy shade, or a move soon.
Check next: the roof’s age and a shade report.
Price and financing
Worth a closer look
A cash price near $3.09 per watt, or a low-rate loan.
Pause and check
A large $0-down offer where the payment, not your usage, set the size.
Check next: the cash price beside the financed price, with all fees.
A typical Michigan system, worked through
Simple payback is the years your savings take to cover what you paid: net cost divided by yearly savings. Here is the typical Michigan system in DTE territory, paid in cash.
- Cash price
- $20,487
- Confirmed incentives
- $0
- Year-one production
- 8,752 kWh
- Used at home / exported
- 60% / 40%
- Average price (EIA, 12 months)
- $0.2105/kWh
- Export credit
- $0.08709/kWh
- Owner-cost allowance
- $200/yr
- Used-at-home value
8,752 × 60% × $0.2105$1,105/yr - Export value
8,752 × 40% × $0.08709$305/yr - Yearly savings after owner costs
$1,105 + $305 − $200$1,210/yr - Simple cash payback
$20,487 ÷ $1,210about 16.9 years
Inputs: the EcoGen Solar Cost Index typical Michigan system (6.63 kW, $20,487 cash, September 2026; 1,320 kWh per kW a year) and DTE’s off-peak outflow credit on its standard D1.11 rate. No rebate is subtracted. The EIA average includes fixed charges, so the rate you really avoid is likely a little lower. Our assumptions: 60% of the solar power used at home, 40% sent to the grid, and $200 a year for owner costs.
Now change only the export credit. Great Lakes Energy, a co-op in the northern and western Lower Peninsula, credits 5.6 cents per kWh for 10 years on systems up to 20 kW.
| Scenario | Export credit | Export value | Yearly savings | Simple payback |
|---|---|---|---|---|
| DTE credit | $0.08709/kWh | $305 | $1,210 | about 16.9 years |
| Great Lakes Energy credit | $0.056/kWh | $196 | $1,101 | about 18.6 years |
The gap comes only from the 40% that leaves the house. The more you export, the more the credit decides your answer; use more at home and both paybacks shrink. If every kWh offset the full average price, the payback would be about 11.1 years, the best case on our Michigan cost page. A well-sized system gets closer to it.

Inflow and outflow: two prices on one meter
Power you take from the grid (inflow) is billed at your normal rate. Power you send out (outflow) earns the credit. Here is the typical system’s split under our 60/40 assumption.
Used at home: 5,251 kWh. Each one replaces power you would have bought, so it saves the full variable rate ($0.2105 here).
Sent to the grid: 3,501 kWh. These earn whatever your utility pays for exports ($0.08709 here). That can be far less.
On DTE’s standard rate, 100 off-peak kWh cost $18.44 to buy before surcharges, because the 9.726 cents per kWh delivery charge is added. Sent out, they earn $8.71. Each utility sets its own credit:
| Utility | Credit for exported power | What to watch |
|---|---|---|
| DTE Electric | 8.709 cents per kWh off-peak; 14.407 cents per kWh in June to September busy hours (3 p.m. to 7 p.m., Monday through Friday). | Credits can pay all electric charges except securitization charges, and carry forward. |
| Consumers Energy | 8.2996 cents per kWh from October to May; 10.397 to 15.1904 cents per kWh in summer. | Ask which rate the quote used. |
| Lansing Board of Water & Light | 7.5 cents per kWh, plus a $500 per kW rebate up to $2,000. | Ask if unused credits carry over. |
| Great Lakes Energy | 5.6 cents per kWh for 10 years. | A limited, first-come offer. |
DTE and Consumers Energy credits are before a small monthly fuel adjustment (the PSCR factor). Michigan homes paid an average of 21.05¢ per kWh from August 2025 to July 2026 (EIA).
Get a size built from your own usage
Ask each Michigan installer for the system size, the share it expects you to export, and your utility’s outflow credit.
Solar providers that serve your area may contact you, and they pay EcoGen for the introduction. How we make money.
How to size a Michigan system to your own use
Start with your bill, not the roof. Add up the kWh on your last 12 bills and divide by about 1,320 kWh, what a kW of panels makes in a Michigan year. Michigan caps a new system at 110% of the electricity you used in the past 12 months anyway.
Then look at when you use it. A home busy at night and empty all day sends more out at the credit, so it should buy smaller or shift some load to midday. Ask for monthly production with a snow loss, not one flat yearly figure.
Be wary of a large $0-down offer. When the payment sets the size, a bigger system earns the seller more and you less per panel. See what free solar really means in Michigan.
Loans, a city rebate and a tax rule that help
Michigan has no statewide rebate for home panels. Michigan Saves lenders post rates as low as 5.99% to 6.99%, with terms up to 180 months; your rate depends on the lender and your credit. A dealer fee can erase years of savings, so compare every loan with the cash price.
Lansing Board of Water & Light pays $500 per kW up to $2,000, which a typical 6.63 kW system reaches. The form asks for a purchase invoice, so a leased system may not qualify. Statewide, the value a home system of 150 kW or less adds stays out of your property assessment until you sell.
For loan terms and a payment calculator, see our solar financing guide.
What to get in writing from a Michigan installer
A quote that cannot show these lines cannot back up its payback number.
- Your usage, then the size. The 12 months of kWh the design used.
- Home use vs export. The share of output used at home and sent out.
- Your utility’s credit. The outflow credit, not retail, for every exported kWh.
- Winter output. Monthly production with snow loss.
- Cash and financed prices. Both totals side by side, with any dealer fee shown.
- HOA approval, if needed. Michigan gives the association 30 days to answer a written application.

How EcoGen is paid
EcoGen America does not sell or install solar. When you request quotes, we pass your request to solar providers serving your area, and they pay us for the introduction. Providers can include installers, solar marketplaces and lead exchanges, and more than one may contact you. You never pay us. This is not an application to the Distributed Generation Program.

Michigan solar, common questions
Are solar panels worth it in Michigan?
They can be, for a sound roof and a system sized to your own use. In our example a typical owned system pays back in about 17 years with DTE’s outflow credit and about 19 with a lower co-op credit. Using more of the power at home, and not oversizing, shortens it.
Is solar worth it in Michigan with the cloudy weather?
Clouds matter less than the credit for exports. A typical Michigan system makes about 1,320 kWh per kW a year, and cold panels work well. Snow trims winter output, so judge a quote on its yearly total with snow loss included. The bigger question is how much of that power your home uses.
Does Michigan still have net metering?
Not for new systems. DTE closed it on May 9, 2019 and Consumers Energy on January 1, 2021. New customers join the Distributed Generation Program: power you use saves the full price, and power you send out earns an outflow credit. Older net metering customers keep their terms for up to 10 years from enrollment.
Is a battery worth it in Michigan?
Only on its own numbers. A battery stores power you would have sent out at the credit and uses it in the evening at the full price. It earns only that gap on the kWh it shifts, and it costs several thousand dollars of its own. Ask for a separate payback line, and count outage backup separately.
Why would an installer suggest a smaller system than my neighbor’s?
Because each extra panel earns less once your home stops using its output. Past that point, the power goes out at the outflow credit, so it adds cost faster than savings. Michigan also limits a new system to 110% of the electricity you used in the past 12 months. A smaller, well-matched quote is often the better one.
How long does solar take to pay off in Michigan?
About 17 years for our typical 6.63 kW example with DTE’s credit, and about 19 at 5.6 cents per kWh. If every kWh offset the full average price, the best case would be about 11.1 years, as on our Michigan cost page. Real systems land between, depending on how much power you use as it is made.
Sources, method and corrections
The example uses the Cost Index typical Michigan system (September 2026) and the DTE and Great Lakes Energy outflow credits. Our assumptions: 60% of the solar power used at home, 40% sent to the grid, owner costs of $200 a year, and every DTE export at the off-peak credit. Simple payback uses flat first-year values. The calculator sends nothing.
