- DTE Energy is the regulated electric utility for Detroit and much of Southeast Michigan, and it runs the interconnection that lets a home solar system switch on (Michigan Public Service Commission, as of August 2026).
- Michigan replaced one-for-one net metering with a distributed generation inflow and outflow tariff, so DTE charges the power you pull from the grid at the full retail rate and credits the power you export at a lower rate based on the supply portion of that rate, not the full retail price (MPSC, as of August 2026).
- Michigan residential power averages about 22.01 cents per kWh (EIA, as of May 2026), among the higher rates in the Midwest, so the bill your solar offsets on site is a large one.
- Michigan raised the old 1 percent cap on distributed generation to 10 percent of a utility’s peak load under 2023 clean energy legislation, which reopened room for new rooftop projects (MPSC, as of August 2026).
- The 30% federal homeowner credit (Section 25D) ended for systems placed in service after December 31, 2025 (IRS, as of 2026), so a 2026 cash or loan buyer cannot claim it, and Michigan’s own value now carries the payback.
If DTE Energy is your electric utility in Detroit or Southeast Michigan, rooftop solar still pays, but Michigan changed how it pays, and that is the part most people miss. DTE delivers your power and runs the interconnection that lets a home system operate. Michigan no longer credits solar exports one-for-one, so understanding DTE’s inflow and outflow tariff is the key to sizing a system that actually saves you money. This page covers who DTE is, the real Michigan rate your solar offsets, exactly how the inflow and outflow credits work, the program cap that reopened, how you connect, and how to tell whether your roof is a good fit, with every figure sourced and dated.

Is DTE your utility in Michigan?
DTE Energy is the regulated electric utility for Detroit and much of Southeast Michigan, and it is also the interconnection authority for rooftop solar there. If your bill says DTE, your solar crediting and interconnection run through DTE and the rules on this page apply. Much of the rest of Michigan’s Lower Peninsula is served by Consumers Energy, which uses a similar inflow and outflow structure but has its own rate and tariff, so the exact numbers differ. Confirm the utility name on your bill first, because the crediting details are set per utility by the Michigan Public Service Commission (MPSC, as of August 2026).
What you pay: the Michigan rate DTE solar offsets
Solar offsets the power you would otherwise buy from DTE, so the rate it replaces is what makes the math work. Michigan residential power averages about 22.01 cents per kWh (EIA, as of May 2026), among the higher rates in the Midwest. The cleanest figure is always your own bill, so divide the total by the kWh you used to see your personal DTE rate, since DTE’s residential price is set in rate cases and moves over time. What matters for solar is that the power your panels replace on site is priced at that full retail rate, which is more than DTE pays you for the surplus you export. For the full Michigan cost and payback picture, see our Michigan solar cost and payback guide.
MySolarFY estimate (August 2026). According to MySolarFY’s analysis (August 2026), a 7 kW rooftop system in the Detroit area produces about 9,034 kWh a year (NREL PVWatts) and, at Michigan’s average residential rate of 22.01 cents per kWh (EIA, May 2026), offsets roughly $1,988 of grid power in its first year when you use that production on site. Your own figure depends on your roof’s pitch, shade, and how much of your solar you consume as you make it rather than export, so treat this as a starting point, not a quote.

How DTE credits your solar: inflow and outflow
DTE prices two flows differently: grid power you buy costs the full retail rate, and surplus you export earns a smaller credit. That is the most important thing to understand about DTE solar, because it changes how you size a system. Michigan retired traditional one-for-one net metering and moved new solar customers to a distributed generation tariff that meters two separate flows (MPSC, as of August 2026). Inflow is the power you draw from the grid when your panels are not making enough, and DTE charges it at your full retail rate. Outflow is the surplus your system sends back, and DTE credits it at a lower rate tied to the supply portion of the retail rate, not the full retail price. In plain terms, the power you use in your own home the moment you make it is worth the full retail rate, while the surplus you export is worth less. For a plain-English primer on how export credits work in general, see how net metering credits your solar exports.
| Flow | What it is | How DTE prices it |
|---|---|---|
| Inflow | Power you buy from the grid when solar is not covering your use | Charged at your full retail rate |
| Outflow | Surplus solar you export back to the grid | Credited at a lower rate based on the supply portion of retail, not full retail |
| Self-consumption | Solar you use in your home as you make it | Worth the full retail rate you avoid paying, the best value of the three |
Why this changes system sizing. Because exports are worth less than the power you use on site, an oversized array that dumps a lot of surplus onto the grid earns the lower outflow credit for that surplus. The exact outflow credit is set in DTE’s rate cases and changes over time, so verify the current figure with DTE or your installer before you count on it. The practical takeaway is to size the system to your own daytime usage, and to consider whether a battery, which lets you use more of your own solar at night, fits your goals.
The Michigan program cap that reopened room for solar
Michigan raised its distributed generation cap from 1 percent to 10 percent of a utility’s peak load, reopening room for new rooftop projects. For years the state capped how much rooftop solar each utility had to enroll, and that mattered because a utility could approach the limit. Under 2023 clean energy legislation, Michigan lifted the cap from the original 1 percent of average peak load to 10 percent, which reopened significant room for new home solar on DTE and the other utilities (MPSC, as of August 2026). Michigan rules also let a residential system be sized up to 110 percent of your prior 12 months of usage, so plan around your own consumption rather than oversizing for export credits that are worth less.
Michigan incentives a DTE customer can use
Michigan’s state stack is leaner than some coastal states, so being accurate about it matters. Michigan has no state income-tax credit for residential solar and no general statewide cash rebate for homeowners in 2026, and it does not exempt solar equipment from sales tax, so do not let a sales pitch add incentives that are not there. What Michigan does offer is a property tax exemption on the added home value from qualifying solar (DSIRE Michigan, as of 2026), confirm the details with your local assessor. For every Michigan incentive, utility, and eligibility detail in one place, see our Michigan solar guide. For the statewide picture, see our guide to solar incentives, and for the 2026 federal picture, see our page on the federal credit that ended after December 31, 2025.
| Incentive | What it gives you | The Michigan detail |
|---|---|---|
| Self-consumption savings | Every kWh you use as you make it avoids the full retail rate, about 22 cents (EIA, May 2026) | The biggest lever in Michigan; size to your daytime use |
| Outflow credit | A per-kWh credit for exported surplus, below the full retail rate | Set in DTE’s rate cases; verify the current figure before you rely on it |
| Property tax exemption | The added home value from qualifying solar is exempt from property tax (DSIRE) | Confirm the current terms with your local assessor |
| State credit or rebate | None statewide for residential solar in 2026 | Do not budget for a Michigan program that does not exist |
How to connect solar to DTE in Michigan
Connecting a home system follows Michigan’s interconnection rules, administered by DTE, and the rule that matters most is that you cannot turn the system on until DTE grants permission to operate (DTE Rooftop Solar and Private Generation, as of August 2026). The general path is:
- Application. Your installer files DTE’s interconnection and distributed generation application with the system design, a one-line diagram, and the inverter data. Most home systems qualify for the simplest review level.
- Review and approval to install. DTE reviews the package and issues approval to install; the application details must match the account holder.
- Permit, install, and inspect. You pull your local building permit, a licensed contractor installs the system, and it passes local electrical inspection.
- Meter and permission to operate. DTE sets the metering that separately counts inflow and outflow, then issues permission to operate, and the system may not run in parallel with the grid before that.
A licensed installer normally manages this whole process, including the interconnection paperwork. Plan for a few weeks of local permitting plus DTE review after installation.
What changed federally, and what it means for DTE customers
The federal homeowner credit is gone: Section 25D ended for systems placed in service after December 31, 2025. People are searching whether the 30 percent solar credit is still available, and the answer is that it is not, so a DTE customer who buys solar with cash or a loan in 2026 cannot claim it (IRS, as of 2026). For the full timeline, see what the end of the federal solar tax credit means in 2026. What carries the payback now in Michigan is the high retail rate you avoid through self-consumption, the outflow credit on your surplus, and the property tax exemption.
One federal exception remains, and it is not yours to claim. A separate commercial credit, Section 48E, is claimed by the business that owns a leased or PPA system, not by the homeowner. On a leased system you do not file for a federal credit yourself, because the company that owns the panels does. The 25D homeowner credit, by contrast, ended after December 31, 2025, so do not let a sales pitch tell a 2026 cash or loan buyer that the 30 percent federal credit is still available.
How to choose a solar installer in DTE territory
Southeast Michigan has a competitive installer market, so vetting matters. Rather than chasing a “best installer” list, screen any company against objective criteria:
- NABCEP certification, the industry’s professional standard for PV installers.
- A valid Michigan residential builder or electrical license for the contractor.
- A clear workmanship and equipment warranty in writing.
- Real experience with DTE interconnection and permission to operate, plus your local building permit, so your system starts on time.
- A written production estimate and a transparent quote that models the inflow and outflow tariff honestly and shows your bill after solar, fixed charges included.
