Michigan’s “free solar” pitches have a math problem the salesperson is counting on you not to check. Under the state’s distributed generation program, power you send out earns an outflow credit below the retail rate, so the oversized systems that make $0-down deals look impressive are exactly the systems that underperform here. No Michigan agency gives panels away. What exists are contracts, and in Michigan the size of the system a contract puts on your roof matters as much as its price.
Bigger is the sales default. Under outflow math, bigger is often just more of the wrong thing.

Why Oversizing Breaks the Free Pitch in Michigan
| System sizing | What happens under Michigan’s inflow-outflow math |
|---|---|
| Sized to your daytime consumption | Most production offsets power you would have bought at full retail; the safest value in the state |
| Oversized “to maximize savings” | The surplus flows out at the lower outflow credit, and in a $0-down deal you are paying full freight for discounted-value production |
| Sized to the payment the salesperson wanted | The most common Michigan outcome; the contract wins, the roof loses |
The numbers under that table: Michigan homes pay about 20.18¢ per kilowatt-hour on statewide average, roughly 13% above the national average (a statewide average for context, not what DTE or Consumers charges), and under the inflow-outflow tariff exported power is credited at the power-supply component of the rate only, not the full retail rate. The inflow-outflow mechanics, and what DTE and Consumers Energy actually credit, live in the Michigan solar incentives guide. The Michigan installer rankings are built on utility-process fluency for the same reason.
The Three Contracts Under the Word Free
- Lease: the company owns the array and sized it; you pay rent on its sizing decision for decades, and most Michigan lease and PPA contracts also raise the payment every year, often 2 to 3%. Over a 20 to 25 year term that escalator can quietly outrun the savings, especially on an oversized system earning the lower outflow credit, so get the escalator rate in writing and total the payments over the full term before comparing anything.
- PPA: you buy the output whether it offsets retail-priced inflow or earns discounted outflow; the rate should acknowledge the difference, and rarely does.
- $0-down loan: you own the system, the sizing, and the dealer fee in the financed total. Get the cash price beside it; what solar costs in Michigan is the yardstick.
The federal residential credit is $0 for home-owned systems whose installation is completed after December 31, 2025. Third-party owners may access business-side treatment; in Michigan, watch whether any of it survives into the payment.
You Likely Will Not Qualify If
- You expect a state giveaway. Michigan does not run one for standard residential rooftops; income-qualified support where it exists runs through utilities and community programs, verified directly.
- Ask what outflow credit the model used. If the answer is none, the savings were modeled on math Michigan does not use.
- Your usage is small or evening-weighted. Outflow-heavy production plus a rising payment is the losing combination.
- Your roof has under 10 years left. Michigan winters make re-roofing under third-party panels everyone’s least favorite clause.
The Michigan Ten-Minute Audit
- Ask what share of production the model assumes you consume on site, and how that came from your actual usage.
- Ask what outflow credit rate the model used for your utility, in writing.
- Compare the proposed size against your daytime load, not your roof area.
- Michigan law caps a new distributed generation system at 110% of your prior 12 months of usage (2023 PA 235). Ask the bidder to show the sizing against that cap; a proposal that ignores it was not built on Michigan rules.
- Get the cash price beside the payment stream, totaled over the term.
- Check the bidder’s DTE or Consumers filing fluency against the Michigan installer list.

Frequently Asked Questions
No. Michigan has no free panel program. “Free” offers are leases, power purchase agreements, or $0-down loans, and under Michigan’s outflow crediting the sizing inside those contracts decides whether they ever pay.
Not a statewide giveaway. Some utility and community programs assist income-qualified households; verify any claim directly with the utility or program named, never through the salesperson citing it.
Under Michigan’s distributed generation program, exported power earns a credit below the retail rate. Self-consumed power avoids full retail. That gap is why right-sizing beats oversizing, and why $0-down deals built on big arrays disappoint here.
Michigan replaced traditional net metering with the inflow-outflow distributed generation structure for new customers. If you enrolled under the old net metering program, you keep those terms for 10 years from enrollment; the outflow math on this page governs new enrollments. Confirm your utility’s current crediting before accepting any savings model.
The company that owns the system. The federal homeowner credit ended for systems whose installation was completed after December 31, 2025; ownership-linked business treatment follows the owner and helps you only if the payment reflects it.
For high-daytime-usage households with sound roofs, a fairly priced deal sized to your usage can work. The test is a model built on your usage and your utility’s outflow rate, surviving with no rate-growth assumptions.
