Solar payback Michigan

Solar panel payback in Michigan

10.7 years for a typical home solar system in Michigan to pay for itself, with no federal tax credit.

A 7.0 kW system sized for the average home here, which uses 632 kWh a month, costs about $19,600 at $2.80 per watt. It saves about $1,610 in its first year, and after 25 years it is $33,655 ahead. That leaves a comfortable margin inside the 25 to 30 years panels usually last.

How Michigan compares

Michigan ranks 15th of 51 for solar payback, fastest first. The fastest is Hawaii at 5.9 years. At U.S. average figures, payback is 12.3 years.

Two things set payback: what each kWh is worth and how many the panels make. Michigan ranks 13th for electricity price, most expensive first, at 23.05¢/kWh, and 48th for sunshine, at an estimated 1,150 kWh a year per kW of panels. Expensive power does the work here; sunshine is below the U.S. average of 1,350 kWh per kW.

The calculator assumes power sent to the grid earns 75% of the retail price, typical of net metering. Your utility's tariff sets the real rate, and a lower credit slows payback.

Solar pays back faster here than in any neighboring state; next is Ohio at 12.8 years.

What these numbers assume

  • A 7.0 kW system, sized to cover about 100% of a typical home's yearly use.
  • $2.80 per watt installed, paid in cash, with no state or local incentives entered.
  • No federal tax credit: Section 25D ended for systems placed in service after December 31, 2025.
  • Half the output used in the home as it is made; the rest credited at 75% of the retail price.
  • Electricity prices rising 3% a year, panels losing 0.5% of output a year, and a $2,000 inverter replacement in year 12.
