What does a ground-mounted solar system cost in Michigan, and what permits does it need?

Why a ground mount is a different job from a roof

Michigan's residential code amendment, R 408.30521a, covers PV panel systems mounted on or above the roof covering, and says they must comply with the code, Section R324 and NFPA 70. That rule is written for roofs and says nothing about footings, so ask your city's building department what it wants for a ground array before you design one.

As the City of Portage's handout reproduces the residential code (it doesn't name the edition), R324.6 says ground-mounted PV systems are designed and installed under R301, and R324.6.1 makes them subject to fire separation distances set by the local jurisdiction. Midland publishes separate building and electrical photovoltaic checklists that ask whether the system is a roof or ground mount and request structural calculations. Cities differ, so the first call is to yours.

What a ground mount costs in Michigan

Our estimate is $19,300 to $25,800 for a typical 7 kW ground-mounted system, before any incentive. It's a model, and a bid will differ. It draws on 4 published national ranges, including those that price the ground-mount premium, scaled by what Michigan solar installers are paid against the US mean, and adds a typical city electrical permit fee. The range leaves out a zoning or building permit for the structure, trenching to the house, or site work.

A federal credit isn't in the range, and none applies to a system installed in 2026. The wage row shows pay and not a price.

How we estimate costs: the Estimated range row comes out of a model, so treat it as a planning figure and never as a quote. It takes 4 published national ranges for this job (cost guides from third-party sites that we haven't verified and don't cite) and multiplies them by Michigan's solar installer wage ratio to the US (0.87, BLS May 2025) and adds a typical permit fee ($94). The range is before any incentive: the federal residential clean energy credit does not apply to systems installed after December 31, 2025. The wage and permit rows are what installers are paid and what the city charges, and neither is a price. We have not collected quotes, and too few Michigan installers publish prices to show a range. Full method. Prices as of Oct 23, 2026.

Where on the lot a city lets the array go

Grand Rapids prints a distance. Its solar guide says ground panels go to the side or rear of the main building, not within 5 feet of a side or rear property line, with adequate screening. Solar is an accessory use in every zone district there, and a home in a historic district needs a Certificate of Appropriateness.

Ann Arbor rewrote its rule in 2024. Ordinance ORD-23-38, effective February 11, 2024 (as of March 2024), says a ground-mounted personal-scale system in a single- or two-family district follows the accessory-structure rules. It may not sit in a front yard and must be screened from the right-of-way. As printed, the ordinance also allows front-yard placement no closer than 10 feet to the lot line, so ask the planning office which clause governs your lot. The 2018 ordinance, whose personal-scale section the 2024 amendment rewrote, set at least 3 feet from the property line, a 21-foot height limit and no more than 35 percent of the required rear setback area.

Dearborn ties a ground array to its accessory-building rules. Its zoning guide says ground-mounted installations "shall be located in the rear yard," and that they "shall comply with height, yard setbacks, and lot coverage requirements for accessory buildings." They count toward lot coverage, which is capped at 35 percent in the one-family RA and RB districts.

In a 2020 MSU Extension survey of Michigan zoning, published September 24, 2020, roof-mounted solar was permitted in more districts than ground-mounted, and ground-mounted allowances grew less common as residential districts got denser. Royal Oak permitted small systems in all districts only as an accessory use, and East Lansing permitted personal-scale systems in all districts by right. Cities may have amended their rules since, so check the current code for yours.

What a city may want for the structure

Several cities treat solar as both a building job and an electrical job. Dearborn's residential solar checklist, updated January 23, 2025, requires both permits and gives 10 business days for review. Its building plan review is "$100 administrative fee + $5 per $1,000 of construction cost with a maximum of $250," and its building permit "$100 + $15 for each additional $1,000 of construction value over $2,000."

The same Dearborn checklist adds that a freestanding system should sit in the rear yard and that the contractor must hold a Michigan license and be registered with the city. Kalamazoo's checklist lists a primary-use ground-mounted PV system as needing an electrical permit and a building permit. It also says arrays and storage systems that meet the International Fire Code's setback requirements need no separate fire service review.

East Lansing's solar checklist asks for zoning compliance with section 50-156 of the city code and a Certificate of Appropriateness in the Historic District. Its building fee is $140 for systems under 10 kW, covering the application and rough and final inspections, and "based on value of construction" above that. Grand Rapids prices its building permit by value too, with a fee calculator on the city's site. Ask your own city which permits a ground array needs and how the building fee is figured.

The utility rules are the same as for a roof

A ground mount joins the same distributed generation program. Public Act 235 of 2023 raised the program cap from 1 percent to 10 percent, set a 550 kW limit and lets a system be sized to 110 percent of your prior 12 months of use. Systems over 20 kW no longer need a generation meter. DTE and Consumers Energy each charge $50 for the application, and at Consumers a system over 20 kW moves from Level 1 to Level 2, which runs to 150 kW.

The power you draw is charged at the retail rate, and the power you send out is credited at the power supply rate. MCL 211.27(2)(p) treats residential PV up to 150 kW, whose output doesn't exceed your annual use, as not adding to the home's assessed value until the property is sold, and the assessor may add it after a sale.

Who builds it and what to ask

The law's definition of electrical wiring covers generating equipment, so ask for the company's Michigan electrical contractor license number and look it up with LARA; Detroit issues its own licenses locally. A homeowner on an owned and occupied single-family home is exempt from the license, not from the permit or the utility. Ask who designs the structure, who pulls the building permit if your city asks for one, and who files the utility application.

Get the usual items in writing: total price with financing and dealer fees, kW DC, cost per watt before any incentive, equipment by model, warranties, and whether it's a purchase, loan, lease or PPA. The quote guide lists them, and the winter and snow guide covers snow on panels.

When to call 911 and when it can wait

What to settle before you design it

1. Call your building department about zoning, setbacks and a building permit.
2. Ask whether fire separation rules apply to the array.
3. Ask who designs and permits the structure.
4. Ask for the electrical contractor license number and look it up with LARA.
5. Ask your utility, DTE or Consumers Energy, how the application works for your size.

Permits for a ground mount

The electrical permit is pulled under the electrical contractor's state license number, and cities set their own fees. A zoning or building permit for the structure may be needed as well, and the model doesn't add one. Dearborn requires both building and electrical permits for solar.

Michigan adopted the 2023 National Electrical Code effective March 12, 2024, and for a house LARA's code page points to the Michigan Residential Code.

Ask for the company's contractor license number and look it up with your state's licensing board before you sign.
