DTE Energy: how it credits the solar power you send to the grid
Outflow credits at the power-supply rate: about 7.75 to 14 cents per kWh, depending on the rate plan and time of day.
Checked November 12, 2026. Utilities change these rules; check the current tariff before you sign.
How it works
DTE pays 7.75 to 14 cents depending on plan and hour; we use the middle, about 10.9 cents. That estimate is about 54% of Michigan's average electricity price.
Michigan's inflow/outflow billing charges full price for everything you take from the grid and pays only the supply part for what you send out.
On DTE's time-of-day plans, outflow during peak hours earns more.
DTE serves Detroit and southeast Michigan; its outflow credit range is a little lower than Consumers Energy's.
What it means for a typical Michigan home
An average Michigan home uses about 7,620 kWh a year. A 5.5 kW system costs about $14,135 at the 2026 median price and makes about 7,101 kWh in its first year, of which we assume about 4,260 kWh goes out to the grid because no one is home to use it.
| First-year savings | Payback | 25-year savings, after the price | |
|---|---|---|---|
| With DTE Energy's credit | $1,033 | 15 years | $16,284 |
| If every exported kWh earned the full price | $1,422 | 10 years | $28,723 |
The difference, about $12,439 over 25 years, is what DTE Energy's rules cost a typical system compared with full net metering. Using more of the power at home, while the sun is up, closes some of that gap. Uses Michigan's average electricity price; DTE Energy's own prices may be higher or lower. Paid in cash, no federal credit, prices rising 2.5% a year, one inverter replacement.
