Quick Answer
Michigan's 2026 solar incentives include the Distributed Generation inflow/outflow program, a 100% property tax exemption on added home value, a 6% sales tax exemption on qualifying equipment, DTE Solar Currents and Consumers SolarCurrents production incentives, the LBWL $500/kW rebate, and Michigan Saves loans. The federal residential tax credit expired after 2025.
Michigan homeowners paid an average residential electricity rate of about 19.3 cents per kWh in early 2026. That is roughly 20% above the national average, according to Palmetto’s Michigan solar market data (2026). That high rate is the single biggest reason solar still works in the state. It offsets the fact that the federal Residential Clean Energy Credit expired for homeowner-owned systems at the end of 2025.
The state’s incentive stack is different from the coasts. There is no large state rebate that every homeowner automatically gets. Instead, Michigan combines a strong property tax exemption, a sales tax exemption on qualifying equipment, and a distributed generation program for export credits. Utility-specific rebates vary sharply by service territory. For installers, the winning proposal is the one that models the customer’s actual utility, rate schedule, and outflow credit correctly.
This guide covers every active Michigan solar incentive in 2026, how the Distributed Generation program changes ROI, and how to stack the programs without overpromising.

Michigan Solar Incentives at a Glance — 2026
Michigan is not a one-size-fits-all solar market. The same 7 kW system can have very different economics in Detroit, Grand Rapids, Lansing, or Marquette because the utility rebate and outflow credit differ. The table below summarizes the main programs active in 2026.
| Incentive | Type | 2026 Status | Typical Value |
|---|---|---|---|
| Federal residential ITC | Tax credit | Expired | $0 for cash or loan residential purchases |
| Federal Section 48E | Commercial tax credit | Active, deadlines apply | 30% for eligible commercial, lease, or PPA systems |
| Michigan property tax exemption | Tax exemption | Active | 100% of added system value excluded |
| Michigan sales tax exemption | Tax exemption | Active | 6% state sales tax not charged on qualifying equipment |
| Distributed Generation program | Bill credit | Active | Outflow credits roughly $0.08-$0.16/kWh |
| DTE Solar Currents | Rebate + production | Verify availability | $2.40/W upfront + $0.11/kWh for 20 years |
| Consumers SolarCurrents | Production incentive | Verify availability | Per-kWh payments over contract term |
| LBWL solar rebate | Local rebate | Active | $500/kW, capped at $2,000 |
| WPPI Energy solar PV rebate | Local rebate | Active in participating territories | Up to $10,000 or 35% of cost |
| Great Lakes Energy battery rebate | Battery rebate | Verify availability | Rebate for qualifying two-way communication batteries |
| Michigan Saves loans | Financing | Active | $1,000-$50,000, up to 15 years |
| Lean & Green Michigan PACE | Commercial financing | Active | Repaid through property tax assessments up to 25 years |
| USDA REAP grants | Rural grant | Active | Up to 50% of eligible project cost for farms and rural small businesses |
The state had about 222 MW of distributed generation capacity enrolled across utilities through 2024, up from roughly 190 MW the year before, according to the Michigan Public Service Commission 2025 Renewable Energy and Distributed Generation report. Growth is steady, but the market is highly utility-specific.
Key Takeaway
Michigan solar works in 2026, but the math is driven by high retail rates, the DG outflow credit, and local utility rebates. The federal residential tax credit is gone, so accurate utility-specific modeling matters more than ever.
The Federal ITC Is Gone for Homeowners. What Still Works?
The 30% federal Residential Clean Energy Credit under Internal Revenue Code Section 25D expired on December 31, 2025. Homeowners who buy solar with cash or a loan in 2026 cannot claim it. This is the single largest change in Michigan’s solar math.
Commercial, third-party-owned, and leased systems may still access the federal Investment Tax Credit under Section 48E. The usual safe-harbor rules apply: construction must begin before July 4, 2026, or the system must be placed in service by December 31, 2027. Lease and power-purchase-agreement providers can pass a portion of that credit through as lower monthly payments. That makes third-party ownership more attractive in Michigan now than it was when the residential ITC was available.
For cash and loan buyers, the federal credit is gone. The rest of the stack must carry the project. That means every installer proposal in Michigan should lead with the property tax exemption, sales tax exemption, DG credits, and any available utility rebate. Do not lead with a federal tax credit that no longer exists.
How Michigan’s Distributed Generation Program Works
Michigan replaced traditional net metering with the Distributed Generation (DG) program under Public Act 235 of 2023. The program uses an inflow/outflow billing mechanism, according to the Michigan Public Service Commission (2026).
- Inflow is electricity you draw from the grid. You pay the full retail rate.
- Outflow is excess solar electricity your system sends to the grid. You receive a credit.
For most residential systems of 20 kW or less, the outflow credit is based on the power-supply component of the retail rate. It is lower than the full retail rate because it does not include distribution and transmission charges. The exact credit varies by utility and rate plan.
| Utility | Typical Outflow Credit | Billing Plan Notes |
|---|---|---|
| DTE Energy | $0.0775-$0.14/kWh | D1-DG flat rate; simpler bill structure |
| Consumers Energy | $0.08-$0.16/kWh | RSP-DG time-of-use; on-peak credits higher |
| Lansing BWL | $0.06-$0.10/kWh | Own crediting rules for municipal customers |
| Indiana Michigan Power | Varies by rate case | Inflow/outflow tariff |
| UPPCO / Alpena / Xcel | Varies | Check current utility tariff |

Program caps and sizing rules
Public Act 235 raised the statewide DG program cap from 1% to 10% of each utility’s average in-state peak load for the previous five years. At least half of that cap must be reserved for systems of 20 kW or less. As of the 2025 MPSC report, DTE and Consumers Energy still had capacity available in the small-system category.
System size is limited to 110% of the customer’s electricity consumption over the previous 12 months, up to a maximum of 550 kW. That means a homeowner cannot install an oversized system purely to earn export credits.
Legacy net metering customers
Customers who enrolled in a utility’s legacy net metering program before the switch keep 1:1 retail-rate credits for 10 years from their enrollment date. After that, they transition to the DG program. New customers in 2026 are on DG from the start.
Michigan State Tax Exemptions
Michigan offers two statewide tax benefits that reduce the effective cost of solar for homeowners and businesses.
Property tax exemption
Michigan law exempts the added value of a solar energy system on residential property from property tax assessments. The exemption covers systems up to 150 kW, which includes virtually every residential installation. It is established under Michigan Compiled Laws Section 211.27(p) and related provisions, according to the Michigan Legislature (2026).
At Michigan’s average property tax rate of about 1.25%, a $25,000 solar system adds about $20,000 in assessed value. Without the exemption, that would add roughly $250 per year in property taxes. Over 20 years, the exemption saves about $5,000. The exemption applies automatically once the system is assessed; homeowners do not need to file annually.
Sales tax exemption
Michigan does not charge the 6% state sales tax on qualifying solar energy systems installed for residential use. The exemption applies to panels, inverters, racking, wiring, and related components when sold as part of a qualifying solar energy system. On a $25,000 system, that saves $1,500 at the point of purchase. The exemption is typically applied by the installer at sale, according to Palmetto (2026) and EnergySage (2026).
Utility-scale property tax treatment
For commercial developers, the Solar Energy Facilities Taxation Act of 2023 provides a 20-year property tax exemption. It applies to qualified utility-scale solar facilities of 2 MW or more, replacing ad valorem taxes with a fixed payment.
Utility Rebates and Production Incentives
Michigan’s most valuable cash incentives are utility-specific. They also change the most frequently, so verify current funding before quoting a project.
DTE Energy Solar Currents
DTE Energy’s Solar Currents program is one of the largest upfront rebates available to Michigan homeowners. Eligible residential customers receive:
- $2.40 per watt upfront rebate
- $0.11 per kWh production incentive for 20 years
For a 7 kW system, the upfront rebate alone is $16,800. The production incentive is paid on all solar generation, not just exports. The program is limited to purchased systems in DTE territory and requires DTE pre-approval. Program availability and capacity should be confirmed directly with DTE before installation. Source: Palmetto Detroit solar guide (2026).
Consumers Energy SolarCurrents
Consumers Energy offers a production-based SolarCurrents incentive for residential customers. The per-kWh rate and contract term vary by program year and available funding. As an illustration, Palmetto estimates that a 9 kW system in Grand Rapids producing about 11,340 kWh per year could earn roughly $284-$397 per year. That totals $2,840-$3,970 over a 10-year contract. Source: Palmetto (2026).
Because this is a performance incentive, system production matters. Accurate shade analysis and production modeling are essential. SurgePV’s shadow analysis tool helps installers get that number right before quoting.
Lansing Board of Water & Light
LBWL offers one of the clearest local rebates in the state. Residential customers receive $500 per installed kW, capped at $2,000 for the first 4 kW. A typical 7 kW system qualifies for the full $2,000. The rebate requires an application, proof of purchase, and equipment specifications. Source: Lansing Board of Water & Light (2026).
WPPI Energy Upper Peninsula rebate
WPPI Energy serves much of Michigan’s Upper Peninsula through member utilities. It offers a solar PV rebate of up to $10,000 or 35% of total installed system cost, whichever is lower. Participating utilities include Alger Delta, Baraga Electric, Crystal Falls, Gladstone Power & Light, L’Anse Electric, Negaunee Electric, and Norway Power & Light. Projects must be pre-approved by the local utility before installation begins. Source: Palmetto (2026).
Great Lakes Energy battery rebate
Great Lakes Energy Cooperative offers a rebate for qualifying home battery storage systems with two-way communication capability. The rebate amount and eligible equipment change, so check directly with Great Lakes Energy. Source: Palmetto (2026).
Financing Options in Michigan
Most Michigan homeowners finance solar with one of four structures. Each changes incentive ownership and long-term value.
Cash purchase
A cash purchase preserves full ownership of DG credits, utility rebates, and any production incentives. It also delivers the highest lifetime savings if the homeowner can afford the upfront cost. The main downside is the longer payback without a federal tax credit.
Solar loan
A solar loan also preserves incentive ownership. Michigan Saves offers unsecured home energy loans from $1,000 to $50,000 with terms up to 15 years. Rates typically fall between 4.44% and 7.90% APR, according to EnergySage (2026). Because Michigan Saves loans do not require home equity, they are a common choice for solar buyers.
Lease or power purchase agreement
A lease or PPA transfers system ownership to a third party. The provider may claim the Section 48E credit and pass part of the savings through as lower monthly payments. The trade-off is that the homeowner usually does not own the utility rebates or production incentives. Always check the contract to see who keeps the incentives and whether the escalator is capped.
PACE for commercial and agricultural properties
Property Assessed Clean Energy financing is administered in Michigan by Lean & Green Michigan. It lets commercial, industrial, agricultural, multifamily, and nonprofit property owners finance solar with no money down. Repayment is added to the property tax bill over up to 25 years. PACE is not available for standard single-family homes. Source: Palmetto (2026).
USDA REAP for rural farms and small businesses
The USDA Rural Energy for America Program provides grants for agricultural producers and rural small businesses installing solar or solar-plus-storage. IRA-funded rounds can cover up to 50% of eligible project costs, with a typical project cap of $1 million. This is one of the strongest federal incentives still available for rural Michigan properties in 2026.

Cost, ROI, and Payback Scenarios
The following examples use illustrative 2026 costs and incentive values. Actual figures depend on location, utility, roof conditions, installer quote, and whether the homeowner qualifies for local programs. The scenarios assume a 25-year system life, 3% annual electricity escalation, and an outflow credit of $0.10/kWh where applicable.
Scenario 1 — 7 kW residential, DTE territory, Solar Currents available
| Item | Amount |
|---|---|
| Gross installed cost ($3.05/W) | $21,350 |
| Michigan sales tax exemption savings | $0 |
| DTE Solar Currents upfront rebate ($2.40/W) | -$16,800 |
| Net cost | $4,550 |
| Annual bill savings (~9 MWh at $0.193/kWh) | $1,737 |
| Annual Solar Currents production incentive (~10,000 kWh at $0.11/kWh) | $1,100 |
| Payback | 1.6 years |
If the DTE Solar Currents program is fully subscribed, the payback stretches significantly. Always confirm program status before quoting.
Scenario 2 — 7 kW residential, Consumers Energy territory, no upfront rebate
| Item | Amount |
|---|---|
| Gross installed cost ($3.05/W) | $21,350 |
| Sales tax exemption savings | $0 |
| Net cost | $21,350 |
| Annual bill savings plus DG credits (~9 MWh, mostly self-consumed) | $1,400 |
| Annual Consumers SolarCurrents production incentive (estimated) | $300 |
| Payback | 12.5 years |
Scenario 3 — 7 kW residential, LBWL territory, $2,000 local rebate
| Item | Amount |
|---|---|
| Gross installed cost ($3.00/W) | $21,000 |
| LBWL solar rebate | -$2,000 |
| Net cost | $19,000 |
| Annual bill savings plus DG credits | $1,450 |
| Payback | 13.1 years |
Scenario 4 — 150 kW commercial rooftop, DTE territory
| Item | Amount |
|---|---|
| Gross installed cost ($2.55/W) | $382,500 |
| Section 48E tax credit (if eligible) | -$114,750 |
| Net cost | $267,750 |
| Annual bill savings and demand reduction | $42,000 |
| Annual DG credits | $4,500 |
| Payback | 5.7 years |
The numbers show why utility territory is the first question a Michigan installer should ask. A system in DTE territory with Solar Currents can pay back in under two years. The same system in a no-rebate territory may take 12 years or more.
How to Stack Michigan Solar Incentives in the Right Order
The order in which you apply incentives matters. The correct sequence is:
- Confirm federal credit eligibility. For 2026 residential cash or loan purchases, the Section 25D credit is not available. Leases and PPAs may still benefit from Section 48E claimed by the system owner.
- Apply for utility rebates before installation. DTE Solar Currents, LBWL, and WPPI require pre-approval or application before work begins. Retroactive applications are usually void.
- Subtract upfront rebates before calculating any commercial tax credit. The tax credit basis is generally the amount paid after rebates.
- Claim the sales tax exemption at purchase. Most installers handle this automatically.
- Receive the property tax exemption automatically. The local assessor excludes the added value once the system is inspected and recorded.
- Enroll in the DG program after interconnection. The utility will switch the meter to a bidirectional meter and start crediting outflow.
Common Mistakes and Misconceptions
Michigan’s patchwork incentive structure means mistakes are costly. Here are the most common errors we see from installers and customers.
Quoting the expired federal ITC
The most expensive error is telling a homeowner they can claim the 30% federal tax credit on a cash or loan purchase in 2026. Section 25D ended on December 31, 2025. Only commercial, lease, or PPA structures can still access federal credits.
Treating DTE Solar Currents as guaranteed
DTE Solar Currents has capacity limits and funding cycles. Do not promise the $2.40/W rebate in a 2026 proposal without confirming current availability and pre-approval requirements.
Oversizing for export
Michigan’s DG program credits outflow at a lower rate than retail electricity. A system sized to 120% of annual consumption may look good in a simple production estimate but leaves value on the table. Size for what the household uses.
Ignoring utility territory
A 7 kW system in DTE territory can have a materially different payback than the same system in Consumers Energy or LBWL territory. The retail rate, outflow credit, and rebate availability all differ. Always model the customer’s actual utility and rate schedule.
Missing the DG program cap
The statewide DG cap is now 10% of utility peak load, but some utilities are filling the small-system allocation faster than others. Check current cap space with the utility before promising interconnection timing.
Assuming all batteries qualify for rebates
Great Lakes Energy’s battery rebate requires two-way communication and eligible equipment. Not every battery on the market qualifies. Verify the model before including the rebate in a proposal.
Conclusion
Michigan’s solar incentive stack in 2026 is a mix of stable statewide benefits and volatile utility programs. The federal residential tax credit is gone. The value now comes from the property tax exemption, sales tax exemption, DG credits, and utility rebates like DTE Solar Currents, Consumers SolarCurrents, LBWL, and WPPI.
For solar professionals, the competitive edge is the ability to model each utility territory correctly. The proposal that wins in Michigan shows the homeowner exactly how the inflow/outflow credit, local rebates, and financing structure interact. Model these factors over 25 years.
SurgePV’s solar design software and generation and financial tool let you build Michigan-specific proposals. They reflect real utility rates, DG credits, and rebate values. For installers scaling in the state, our guide for solar installers covers proposal automation and compliance workflows.
Three actions to take now:
- Confirm utility territory and current DG rates before every quote — territory drives payback more than panel choice.
- Apply for utility rebates before installation begins — most programs reject retroactive applications.
- Size for self-consumption, not maximum export. The DG outflow credit is lower than the retail rate, so every exported kWh is worth less than one used on site.
Frequently Asked Questions
What solar incentives are available in Michigan in 2026?
Michigan homeowners can use the Distributed Generation program for bill credits. They also get a 100% property tax exemption on added home value and a 6% state sales tax exemption on qualifying solar equipment. Utility-specific programs include DTE Solar Currents, Consumers SolarCurrents, the Lansing Board of Water & Light $500/kW rebate, and WPPI Energy rebates in the Upper Peninsula. The federal residential tax credit expired for systems placed in service after December 31, 2025.
Does Michigan have net metering for solar?
Traditional 1:1 net metering is no longer available for new customers of most major utilities. It was replaced by the Distributed Generation program, which uses inflow/outflow billing. Customers pay the full retail rate for electricity drawn from the grid and receive a lower credit for excess solar sent to the grid. A small number of municipal utilities and cooperatives still offer traditional net metering.
Is the federal solar tax credit still available in Michigan in 2026?
No. The 30% federal Residential Clean Energy Credit under Internal Revenue Code Section 25D expired for homeowner-owned systems placed in service after December 31, 2025. Commercial, leased, and power-purchase-agreement systems may still qualify for Section 48E. Construction must begin before July 4, 2026, or the system must be placed in service by December 31, 2027.
How does Michigan’s Distributed Generation program work?
The Distributed Generation program separates electricity you buy from the grid (inflow) from electricity your solar system exports (outflow). Inflow is billed at the full retail rate. Outflow is credited at the power-supply portion of the rate, typically between $0.08 and $0.16 per kWh depending on the utility and time of day. Credits roll over month to month. System size is capped at 110% of your prior 12 months of usage or 550 kW.
What is the DTE Solar Currents program?
DTE Energy’s Solar Currents program offers eligible residential customers an upfront rebate of $2.40 per watt of installed solar capacity. It also pays a 20-year production incentive of $0.11 per kWh for all solar electricity generated. The program is limited to DTE service territory and purchased systems. Program availability and funding should be confirmed directly with DTE before signing a contract.
Does Michigan have a state solar tax credit?
No. Michigan does not offer a state income tax credit for residential solar. The main state-level benefits are the property tax exemption on added home value, the sales tax exemption on qualifying equipment, and the statewide Distributed Generation program.
Will solar panels increase my property taxes in Michigan?
No. Michigan law exempts the added value of a residential solar energy system, up to 150 kW, from property tax assessments. The home itself can still appreciate for other reasons, but the solar equipment value is excluded. This exemption is automatic once the system is assessed.
What is the Lansing Board of Water & Light solar rebate?
LBWL offers Lansing-area residential customers a solar rebate of $500 per installed kW, capped at $2,000 for systems up to 4 kW. The rebate requires an application and proof of purchase. It can be combined with Michigan’s sales tax exemption and LBWL’s distributed generation credits.
What is the typical solar payback period in Michigan in 2026?
Payback periods for well-designed residential solar systems in Michigan typically range from 9 to 14 years in 2026 without the federal residential tax credit. Systems in DTE territory with Solar Currents, or in Lansing with the LBWL rebate, can pay back closer to 8 to 10 years. Results depend on utility territory, system size, outflow credit rate, and financing cost.
What is the most common mistake when sizing a solar system in Michigan?
The most common mistake is oversizing for export. Because the Distributed Generation program credits outflow at a lower rate than retail electricity, excess production is worth less than self-consumed production. The safer design rule is to size the system for roughly 90-100% of annual usage and treat exports as a bonus.
