Solar Panel Cost in Michigan (2026): Price, Payback, Incentives

Q: How much do solar panels cost in Michigan?

At the state median installed price of $3.60 per watt (estimate), a 5.7 kW (estimate) system that covers a typical home's use costs about $20,500 (estimate) before incentives. Quotes vary with roof, equipment and installer.

Solar Panel Cost in Michigan

A typical Michigan home uses 618 kWh a month^[1] of electricity. Covering that with solar takes a system of about 5.7 kW est.^[1,2], which costs roughly $17,500 to $23,500 est.^[1,2,3] before incentives at the state's median installed price. With Michigan's average residential price of 21.73¢ per kWh^[4], our model puts payback at about 17 years est.^[1,2,3,4,5]. Your quote, roof and utility plan will move these numbers, so treat them as a starting point.

Solar cost in Michigan by system size

Same assumptions as the typical home above; only the system size changes. Prices are the state median before incentives and include the incentives our calculator applies by default in Michigan.

Incentives that lower the price in Michigan

Federal · tax creditEnding soon

Business credit for leased and PPA systems (48E)

Claimed by the system owner, not the homeowner; solar must begin construction by July 4, 2026 or be in service by December 31, 2027^[6]

If a company owns the panels on your roof (a lease or power purchase agreement), that company may claim the business clean electricity investment credit and can reflect it in your price. You cannot claim it yourself.

Who: Third-party-owned systems (leases and PPAs). Ask the provider whether the price assumes this credit.
Deadline: December 31, 2027

How Michigan utilities credit your solar

Michigan's regulated utilities run an inflow/outflow distributed generation program: customers pay retail for power drawn from the grid and get a credit below retail (the power-supply portion of the rate) for each kWh sent to the grid. Since PA 235 of 2023, outflow credits can offset all charges except securitization and excess credits bank forward without expiring.^[5]

We have not added every Michigan utility yet, so the estimates on this page use the state-level rule: Michigan credits exports below the retail rate; until we add your utility's rate we assume 8.69¢ per kWh, 40% of the state's average price (assumption).

Frequently asked questions

How much do solar panels cost in Michigan?

At the state median installed price of $3.60 per watt est.^[3], a 5.7 kW est.^[1,2] system that covers a typical home's use costs about $20,500 est.^[1,2,3] before incentives. Quotes vary with roof, equipment and installer.

How long does solar take to pay for itself in Michigan?

For a cash purchase at the state's average electricity price of 21.73¢ per kWh^[4], our model estimates about 17 years est.^[1,2,3,4,5]. Your utility's export credit and rate plan matter a lot; see the export-credit table above.

Is there still a federal solar tax credit?

Not for homeowners who buy. The Federal Residential Clean Energy Credit (25D)^[7] does not apply to systems whose installation is completed after December 31, 2025. Leased and PPA systems are different: the company that owns the system may still claim a business credit.
