Is solar worth it in Michigan?

What drives solar payback in Michigan

Michigan homeowners pay about 20.5¢/kWh, which is 2.1¢ above the national average. A rooftop here generates roughly 1200 kWh per kW each year — below the typical US figure. On exports, Michigan offers partial / below-retail export credit: Distributed-generation tariff pays below retail for exports.

A worked example

For a Michigan home with a $179/month power bill (typical household usage at Michigan’s rate):

That nets out to a payback of about 17.7 years — shorter than simply dividing net cost by year-one savings, because power prices climb ~2.5%/yr so your savings grow each year. Year-one savings already reflect Michigan’s below-retail export rate (you save full value on the power you use as it’s made, less on what you export), which is why they’re lower than the bill. Assumes 3.00 $/W installed before incentives and a typical 40% self-consumption; your actual cost, roof and usage will differ — adjust the calculator above.

Who supplies your power in Michigan

Michigan is dominated by two big investor-owned utilities — DTE Energy, which serves southeast Michigan including metro Detroit, and Consumers Energy, which covers most of the rest of the Lower Peninsula. Between them they serve the large majority of homes. Smaller investor-owned providers include Indiana Michigan Power (I&M) in the southwest and Upper Peninsula Power Company (UPPCO) and other utilities up north. Add municipals such as the Lansing Board of Water & Light and rural electric co-operatives like Great Lakes Energy and Cherryland Electric. The investor-owned utilities all operate under the Michigan Public Service Commission's distributed-generation rules, so export terms are broadly similar statewide; co-ops and munis set their own, often less generous, terms.

What you’re paid for what you export

2018 is the year that matters here: that's when Michigan retired true retail net metering. Its replacement, the MPSC's distributed-generation tariff, splits your solar into two prices. Power you use as it's generated still offsets the full retail rate — about 20.3 cents — but anything flowing out to the grid is credited only at a reduced rate tied to the utility's power-supply (energy) component, noticeably less than what you pay to buy it back. In practice the grid is a stingy trading partner, and the economics reward keeping your own power. Size to your daytime load rather than overbuilding to bank credits, and give a real battery a serious look — shifting your midday surplus into the evening beats selling it at avoided-cost money.

Michigan incentives & taxes in 2026

There's no sugar-coating this one: no state solar tax credit, no statewide rebate worth naming, no SREC market — and now nothing federal either, so a 2026 owned system stands entirely on its own maths. The one genuine bright spot is property tax: under Michigan's Mathieu-Gast home-improvement exemption, qualifying residential solar is generally excluded from your home's taxable value, so the panels shouldn't raise your bill. Odd pockets of support do surface — Lansing Board of Water & Light customers, for instance — and low-income and weatherisation help exists through separate channels, but a typical owner-occupier buying a grid-tied system should expect the sticker price to be, more or less, the price.

The 30% federal credit ended on 31 December 2025 and can now only reach a homeowner indirectly through a lease or PPA. Check the current state and utility programs on DSIRE’s Michigan list, then type any incentive into the calculator above to see how it shortens your payback.

What solar costs in Michigan

A 7-8 kW Michigan system comes in at the low-to-mid $20,000s gross, from per-watt pricing of $3.00 to $3.40 — much what the rest of the country pays. Straightforward jobs on larger roofs sit at the bottom of that band; small or complicated installs climb above it. And because nothing meaningful offsets it, that gross figure is the one that goes straight into your payback arithmetic.

The honest verdict for Michigan

Michigan asks a lot and gives back slowly. Rates near 20.3 cents/kWh do real work, but output is a modest 1,200 kWh per installed kW a year, exports earn below retail, and the incentive cupboard is close to bare — so payback on a grid-tied owned system commonly stretches into the mid-teens of years. The path to making it work is narrow but real: size tightly to daytime use, self-consume aggressively (ideally with a battery), and take a view that utility rates will keep climbing. Just know exactly what you're buying — this is no longer an easy yes.

Driving electric — or heating electric — in Michigan?

Your home electricity rate also sets what it costs to charge an EV and whether a heat pump beats a gas furnace. See the Michigan EV charging cost and the Michigan heat pump vs gas comparison.
