Why this number

Solar panels in Michigan cost about $2.91 per watt — $23,280 for a typical 8 kW system — and pay back in roughly 19.7 years at the state’s 23.1¢/kWh average rate, with the 2026 federal credit at $0. Net billing pays exports below retail here.

Everything below uses Michigan’s real average residential electricity rate (23.1¢/kWh, EIA) and a production band of about 1,205 kWh per kW per year. Both are stated openly because they are the two inputs that decide the answer. These are estimates for sanity-checking a quote, not a quote.

Run it with your own numbers

Why Michigan’s payback lands where it does

Michigan’s rate climbed about twelve percent to 23.1 cents per kilowatt-hour this July from 20.55 cents last July, landing the state at rank 12 nationally. With yield at just 1,205 kilowatt-hours per installed kilowatt — on the low side, reflecting Michigan’s cloudier climate — the payback still runs to 19.7 years despite the above-average rate. DTE Electric, the state’s largest utility serving over 2 million residential customers, prices at 20.1 cents, below the statewide average, so DTE customers likely face a somewhat longer payback than the 19.7-year state figure. Consumers Energy, the next-largest utility, runs close behind at 19.1 cents. Michigan compensates exports under net billing rather than full retail, so it’s self-consumption at that rising rate — not the export credit — offsetting a weak solar resource here; without the double-digit rate growth, the payback would look considerably worse.

Electric utilities in Michigan

The state average hides real spreads between utilities. The largest residential utilities EIA-861 lists for Michigan, with each one’s own average bundled residential price (2024 — revenue ÷ sales, the audited annual figure, not this month’s tariff):

Your utility decides Michigan’s real number — the ZIP lookup finds it in three clicks; the 2024 annual utility averages above sit apart from the June-2026 monthly 23.1¢ state figure.

An 8 kW system in Michigan, priced out

The $2.91/W used above comes from EnergySage marketplace quotes (August 2026). Those are quotes in a competitive online market, not signed contract prices.

Read that table with one caveat: $2.91/W is Michigan’s market average, and it is the input most likely to differ for you. A quote $0.50 per watt above or below the $2.91 used here moves the payback by roughly a year and a half in either direction.

How much sun Michigan actually gets

A kilowatt of panels in Michigan produces about 1,205 kWh a year on an unshaded, south-facing roof at a 20-degree pitch. Sites that swap Michigan’s 1,205 kWh for a single national average are how Arizona and Washington end up with identical paybacks despite a 1.6x real difference in output.

That figure is a five-point cluster around Michigan’s largest metro area, which keeps it representative of where most people actually live rather than of the state’s best site.

City-level figures for Michigan

We have separately modeled production for 1 Michigan city, and they are 0% apart — Detroit at 1,247 kWh per kW against Detroit at 1,247. Installed cost held at $2.91/W; paybacks use each city’s own utility tariff and export treatment where we have official EIA-861 data, which is why some differ sharply from this page’s state-average model.

• Detroit — 1,247 kWh per kW, payback about 21.4 years (on its own utility’s tariff)

Those are real PVGIS-NSRDB location points, not the state figure scaled by guesswork. All Michigan and other city figures .

Two adjustments matter before you apply this to your own roof:

• Shading and orientation. The 1,205 kWh figure assumes an unobstructed south-facing array. A real Michigan roof — its own azimuth and pitch, a tree or a chimney — typically produces 10-25% less; this page models 90% of the ideal, so the 8,676 kWh/year above is already derated from 9,640. A genuinely unshaded south roof can adjust upward in the calculator.
• Year-to-year weather moves output by roughly ±5% either way. Snow is not modeled either, and costs a further 2-5% in a state like this one.

How Michigan compares with the other 49

Michigan ranks 12th of 50 on electricity price and 10th on annual output value per kW installed — close enough that its rate is a fair proxy for its solar case, which is not true everywhere. Its immediate neighbors on price are Vermont (23.8¢) just above and Pennsylvania (21.7¢) just below.

Vermont is Michigan’s closest comparable-rate analogue — 23.8¢/kWh, roughly 1,125 kWh per kW, and a payback about 4.3 years apart (15.4 vs 19.7 years). Use it as a directional marker rather than a proxy — the gap is real.

Net billing: the rule that decides solar in Michigan

Michigan does not credit exports at the retail rate — this is net billing , not net metering. The program is Distributed Generation Program, in force since 2019-05-09, and it credits surplus power at an assumed 6.9¢/kWh, about 30% of retail, because no per-kWh figure is published — against a retail rate of 23.1¢.

Because a typical Michigan home uses only about 40% of its generation as it is produced, most of what the panels make is sold at 6.9¢. That is why the payback above is 19.7 years rather than the 11.3 years the same hardware would return under full-retail net metering. Raising self-consumption — a battery (worth its own arithmetic: is a home battery worth it? ), an EV charged in daylight, daytime occupancy — is the lever that closes the gap. Whether a Michigan buyer should own a battery or take a lease/TPO deal is priced in the battery buy vs. TPO calculator .

Unresolved conflict: the MPSC consumer brochure describes full retail for systems up to 20 kW, while DTE and Consumers inflow/outflow tariffs credit exports roughly 7c below retail. Verify against your own utility’s tariff.

One limit worth knowing: this reflects investor-owned, state-regulated utilities; Michigan’s municipal utilities and co-ops are exempt in most cases and set their own terms.

What is actually left in Michigan

The 30% federal credit ended for systems completed after December 31, 2025, so it is $0 here as everywhere. What remains is state, utility and local — and it varies far more than the federal rule ever did.

Michigan offers no state-level solar tax credit or rebate. Utility-level rebates, and the tax exemptions below, are where any remaining help comes from — those are set locally, so DSIRE and your own utility are the places to look.

Tax exemptions

There is no property-tax exemption, so a system may raise your assessed value. Ask your assessor what it would add.

If that list looks thin, it is — the solar incentives hub shows which states still put real money on the table, and where Michigan sits among them.

Is solar worth it in Michigan at 23.1¢/kWh?

Michigan is workable but unspectacular. At 23.1¢/kWh the rate does the lifting while 1,205 kWh per kW adds little, so your quoted price and your export terms decide the outcome rather than the geography.

At a horizon that long, owning the roof is not the only route to cheaper power. Community solar versus rooftop walks through the subscription alternative — no roof, no loan, and no 19.7-year wait — which is worth reading before committing capital in a market like Michigan’s.

Two numbers put that in context. At Michigan’s rate, the electricity an 8 kW system would produce is worth about $1,160 a year, so the system costs roughly 20.1 years of that output to buy outright — a simple division, before costs. The headline 19.7-year figure above is the full model: it additionally counts 2.5%/yr rate inflation, $150/yr of running costs and one inverter replacement, which is why the two differ slightly. And doing nothing is not free: 25 years of that same electricity, with rates rising at 2.5% a year, comes to about $68,316.

For a 15-year payback in Michigan — given its sunshine rather than a national average — the electricity rate would need to be about 18.2¢/kWh. Michigan is at 23.1¢, which is comfortably above that line.

Frequently asked questions

How we calculated this

Worked for Michigan: 8 kW × 1,000 × $2.91/W = $23,280 gross (federal credit $0, so net before state incentives); 8,676 kWh a year × the blended kWh value at 23.1¢ retail and 6.9¢ export ≈ $1,160 year-1 saving; payback ≈ $23,280 ÷ $1,160 = 19.7 years with 2.5%/yr rate growth, 0.5%/yr degradation and one inverter replacement in the 25-year model.
