How Detroit homes get paid for solar

Export rules are set at the state and utility level, not by the city. Detroit is under Michigan's net billing: Michigan's Distributed Generation program bills inflow at full retail and credits outflow at the power supply rate minus transmission; it replaced net metering in 2019 (DTE) and 2021 (Consumers). The full rules, incentives and sources are on theMichigan page.

Why the city matters

Two things change from one city to another in the same state: the sun, which sets how many panels you need, and the utility, which sets what exported power is worth. Detroit gets 1,249 kWh per kW a year on a south-facing roof at a 20° tilt, so covering a year of use for a $150 bill at 21.5¢ takes about 6.7 kW, roughly 17 panels of 400 W. Electricity prices in the calculator are the Michigan residential average; your utility's rate can be higher or lower, so put your own bill in.
