Is solar worth it in Michigan?
Short answer for a typical Michigan home: a reasonable payback if you'll stay put — roughly 10.0 years to break even after the 30% credit. Run your own bill through the calculator below.
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 $17,930 after the 30% federal tax credit, paying for itself in about 10.0 years and netting on the order of $43,435 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.
