Why savings vary by location

Federal credits no longer apply to 2026 installations, so every dollar saved depends on Wisconsin-specific programs at the state, utility, and local levels.

Because these incentives differ by utility and locality, your savings math is local rather than federal.

DSIRE is the authoritative, regularly-updated source to check current state, utility, and local incentives.
