Is solar worth it in Michigan?

Michigan gets limited sunshine — about 3.8 peak sun hours a day — and residential electricity runs around $0.19/kWh. For a typical $150-a-month power bill, that points to roughly a 8.5-kW system costing about $25,614 — with no federal tax credit, which ended for installations completed after December 31, 2025 — paying for itself in about 14.2 years and netting on the order of $35,751 over 25 years. Your own numbers will differ — the calculator above uses your real bill.

Michigan's sun is on the low side and net metering was replaced with a less generous inflow/outflow tariff, so size your system to your own usage. Above-average rates still make a right-sized system worthwhile.

What changes the math in Michigan

• Your electricity rate — the more you pay per kWh, the more each solar kWh saves you. Michigan sits at about $0.19.
• Sun hours — more sun means a smaller, cheaper system covers the same usage. Michigan averages ~3.8 hours.
• Net metering / buyback — how your utility credits power you export swings the payback; check your specific utility's current terms.
• Install cost — quotes vary by installer and roof; the calculator defaults to a typical $/watt you can override.

Michigan: the rules that actually decide your payback

Who your utility is, and why it matters

DTE Energy covers metro Detroit and the eastern thumb; Consumers Energy covers most of the rest of the Lower Peninsula. Both replaced classic net metering with the state's Distributed Generation (DG) program years ago, and both compensate exports well below what you pay for power.

What your exported power is worth

Under the DG program, DTE credits exports at roughly 7.75-14¢/kWh depending on your rate, against retail power around 16-17¢ — every exported kilowatt-hour is a small loss versus one you self-consume. Consumers runs an inflow/outflow billing scheme with the same shape. DTE also proposed new solar-customer fees in its 2026 rate case; anything pending before the MPSC belongs in the 'confirm in writing' column of any quote.

The Michigan incentive layer

Michigan has no state tax credit for solar. Utility pilots have occasionally paid per-watt rebates or production incentives, but they open and close; treat anything a quote assumes as unconfirmed until the utility confirms it in your interconnection paperwork.

Battery and self-consumption

With the widest retail-versus-export gap among major states, self-consumption is the whole game in Michigan. A battery that shifts your evening load onto your own afternoon production earns the full retail spread — roughly eight to nine cents on every shifted kilowatt-hour — which is why storage quotes here deserve genuine math rather than a brochure. Michigan's winter production dip also argues for batteries sized against shoulder-season usage rather than peak-summer output; an honest model shows monthly production against monthly consumption side by side.

What to check on a Michigan quote

• Ask which DG tariff and rate schedule the savings model assumed — DTE export value varies meaningfully by rate, and the model must use yours.
• Confirm whether any pending DTE fee for solar customers (the 2026 rate case) is included in the payback model or ignored.
• If a Consumers Energy quote assumes net metering rather than inflow/outflow billing, the model is outdated — ask for the version with hourly netting.
• Size to daytime usage first: Michigan's export credit is the least generous among the states we cover in depth.
