Net metering, tax credits and incentives in 2026
Michigan pays less than retail for exported solar power. Under Distributed generation inflow/outflow, power you send to the grid earns about 10.8¢/kWh, against 21.5¢ for power you buy. We assume 40% of a no-battery system's output is used at home as it's produced (worth the full price) and the rest is exported, so each solar kWh is worth about 15.1¢. Using more of your solar yourself, by running appliances midday or adding a battery, raises that.
DTE and Consumers Energy bill all power drawn from the grid at retail and credit exported power at roughly the power-supply part of the rate, about half of retail. Source.
There is no federal tax credit for buying home solar installed in 2026. The 30% Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, so the costs and paybacks on this page include no federal credit.
Michigan and local utilities may still offer rebates, performance payments, property-tax or sales-tax exemptions. Search the DSIRE incentives database for Michigan and ask installers which programs they apply for you.
