Michigan Solar Laws

Michigan’s mature clean-energy policies have made understanding solar energy laws more important than ever for homeowners and businesses. The state’s approach to renewable energy is defined by a blend of federal incentives, statewide regulatory oversight, and locally enforced permitting rules. Whether you live in Detroit, Grand Rapids, or the Upper Peninsula, it’s essential to know how Michigan solar laws, local building codes, and utility regulations interact before starting a solar installation. Michigan law also provides a framework for solar easements and local solar panel roof regulations to ensure systems are safe, effective, and fair to property owners and communities.

Federal Regulations and Policies Affecting Solar Installation in Michigan

Residential Clean Energy (ITC/25D)

Homeowners in Michigan can take advantage of the federal Residential Clean Energy Credit (Internal Revenue Code §25D), commonly known as the Investment Tax Credit (ITC). This credit allows homeowners to deduct 30% of the total cost of a solar system (including panels, batteries, wiring, and labor) from their federal taxes. The 30% credit applies through 2032 and then steps down gradually through 2035. For Michigan residents, this federal benefit substantially reduces upfront installation costs.

National Electrical Code (NEC)

Solar systems in Michigan must comply with the National Electrical Code (NEC) to ensure safe installation and operation. Articles 690 and 705 of the NEC cover requirements for photovoltaic systems, grounding, labeling, and interconnection with the grid. The Michigan Department of Licensing and Regulatory Affairs (LARA) enforces the NEC through the Michigan Electrical Code, which adopts the latest national standards. Local inspectors use these rules when approving permits and conducting final inspections.

Equipment Safety and Interconnection Standards (IEEE 1547/UL 1741)

All grid-tied solar installations in Michigan must use inverters and electrical components certified under UL 1741 and compliant with IEEE 1547 standards. These ensure that solar systems interact safely with the power grid by preventing issues like back-feeding or voltage instability. Utilities such as DTE Energy and Consumers Energy require these certifications as part of their interconnection approval process.

Fire Code/Roof Layout Considerations

Solar installations must also comply with state and local fire-safety rules. Michigan’s building departments enforce guidelines derived from the International Fire Code (IFC) and National Fire Protection Association (NFPA) standards. These rules specify roof setback distances, access pathways for firefighters, and proper labeling to identify electrical components. Adhering to these fire code requirements is necessary for obtaining final inspection approval.

Michigan Solar Regulations and Policies

Interconnection Rules (Michigan Public Service Commission)

The Michigan Public Service Commission (MPSC) regulates how solar energy systems connect to the state’s electrical grid. These rules, outlined in the Electric Interconnection and Net Metering Standards, require all grid-tied systems to undergo a formal interconnection review. Residential systems up to 20 kW are eligible for a simplified process, while larger systems go through detailed engineering assessments. Utilities must respond to interconnection applications within specific timelines, ensuring transparency and predictability for solar customers.

Distributed Generation (Net Metering Successor Program)

Michigan transitioned from traditional net metering to the Distributed Generation (DG) program in 2019. Under DG, customers receive credit for excess electricity sent to the grid at the utility’s avoided cost rate rather than the full retail rate. Although this results in slightly lower compensation than legacy net metering, it still provides meaningful savings by offsetting grid consumption. Homeowners who joined the original net metering program before 2019 can remain grandfathered under older, more favorable credit terms for up to 10 years.

Renewable Portfolio Standard (RPS)

Michigan’s Clean and Renewable Energy and Energy Waste Reduction Act requires utilities to supply at least 15% of their electricity from renewable sources. Solar power plays a key role in meeting this target, and new legislation under the state’s Clean Energy Future Plan aims to expand renewable generation to 60% by 2035. This policy framework continues to encourage residential and commercial investment in solar energy systems.

Property Tax and Sales Tax Exemptions

Michigan offers property tax benefits to solar system owners. Under Public Act 342 of 2016, solar installations on residential properties are exempt from being counted as “true cash value” for property tax purposes. This means installing a solar energy system will not increase your property’s taxable value. In addition, Michigan exempts solar panels and related equipment from the state’s 6% sales and use tax, further lowering installation costs.

HOA-Related Considerations in Michigan

Michigan currently has no statewide HOA solar law preventing homeowners’ associations from restricting or regulating solar installations. Instead, local ordinances and neighborhood covenants determine whether solar is allowed. Some municipalities have adopted solar-friendly zoning ordinances that limit the ability of HOAs to prohibit systems outright. Homeowners planning to install solar should review their community’s bylaws and, if necessary, negotiate solar easements or design modifications that satisfy HOA aesthetic standards without violating state code.

Does Michigan Have Solar Access Laws?

Michigan recognizes solar easements as a means for property owners to legally secure access to sunlight across adjacent properties. These agreements, governed by Michigan Compiled Laws §565.35, are voluntary and recorded in the county land records. A solar easement specifies the vertical and horizontal angles of sunlight protected, ensuring that future buildings or vegetation do not block a system’s solar exposure.

While Michigan does not have a formal solar access law guaranteeing every property owner unobstructed sunlight, it provides a framework for neighbors to create enforceable agreements protecting solar investments. Some local governments, such as Ann Arbor and Traverse City, have incorporated solar access considerations into their zoning codes, discouraging development that would shade existing systems.

The difference between solar access and solar easements is important:

Solar access laws protect the right to receive sunlight through legislation or zoning codes.
Solar easements are private contracts between property owners that ensure continued sunlight exposure for a specific installation.

These mechanisms allow solar customers to preserve long-term access to solar energy even as communities evolve.

Do You Need Permits for Solar Installation in Michigan?

Yes. All residential and commercial solar installations in Michigan require local permits and inspections to ensure compliance with building, electrical, and safety codes. The primary permits include:

Electrical Permit: Required statewide under the Michigan Electrical Code and issued through the Department of Licensing and Regulatory Affairs (LARA) or local authorities.
Building Permit: Needed for roof-mounted or ground-mounted systems to verify structural integrity, load calculations, and wind resistance.
Zoning or Site Plan Approval: Some cities require zoning approval, particularly for ground-mounted arrays or installations near property lines.
Utility Interconnection Approval: Necessary before a solar system is connected to the power grid.

Certain historic districts, such as those in Detroit or Grand Rapids, may also require design or preservation review before approving rooftop installations. Working with a certified installer ensures compliance with all these requirements.

How to Obtain Permits for Solar Installation in Michigan

Although local processes vary, the general procedure for obtaining solar permits in Michigan follows a similar pattern statewide. Proper permitting ensures safe installation and smooth interconnection with your utility provider.

Step 1: Site Evaluation and System Design
A licensed installer assesses your property, roof condition, shading, and local solar panel roof regulations. The system design must meet state electrical and structural codes and comply with municipal zoning ordinances.

Step 2: Prepare Permit Applications
The installer prepares detailed construction drawings, electrical one-line diagrams, and equipment specifications. These documents are submitted to your local building department along with permit fees.

Step 3: Apply for Electrical and Building Permits
Both permits are typically filed together. The electrical permit must be obtained by a licensed electrician authorized in Michigan.

Step 4: Utility Interconnection Request
Your installer submits an interconnection application to your serving utility, such as DTE Energy, Consumers Energy, or UPPCO. The utility reviews your design, confirms compliance with IEEE and UL standards, and issues conditional approval to connect.

Step 5: Installation and Inspections
After installation, local inspectors verify compliance with the Michigan Electrical Code, NEC standards, and fire safety rules. Once approved, final inspection documentation is sent to the utility.

Step 6: Permission to Operate (PTO)
The utility installs or reprograms your meter and grants permission to operate. Once PTO is received, your solar system can legally send power to the grid and begin generating savings through Michigan’s Distributed Generation program.

Step 7: Record a Solar Easement (Optional)
If neighboring properties pose potential shading risks, you can record a solar easement with the county registrar to protect your system’s sunlight access.

Recent adjustments to new solar laws in Michigan have primarily focused on updating interconnection timelines and aligning state rules with federal standards. While Michigan does not yet have broad HOA or statutory solar access laws, its combination of property rights, tax exemptions, and utility regulations provides a stable and supportive foundation for solar growth across the state.
