Michigan
Rooftop solar in Michigan
Michigan's residential solar economics run through two dominant investor-owned utilities — DTE Energy in the Southeast and Consumers Energy across most of the rest of the state. Michigan uses an inflow/outflow billing structure that pays a different rate for power sent to the grid than for power drawn from it, which changes the math compared to states with one-to-one credit arrangements.
Utility coverage
DTE Energy
Investor-owned utility serving Detroit, the Downriver communities, and most of Southeast Michigan including Wayne, Oakland, Macomb, and Washtenaw counties.
Consumers Energy
Investor-owned utility serving most of Michigan outside the DTE service area — Grand Rapids, Lansing, Kalamazoo, and the broader West Michigan and Northern Lower Peninsula regions.
Municipal and cooperative utilities
A number of Michigan cities run their own municipal electric utilities (Lansing BWL, Holland BPW, others), and rural cooperatives serve much of the Upper Peninsula. Solar economics for these addresses don't follow DTE or Consumers rules.
