South Dakota solar notes
South Dakota has no statewide net-metering law, so export compensation depends entirely on each utility, and low rates make solar a slower payoff.
Heads up: the 30% federal tax credit for purchased home solar ended Dec 31, 2025. Leased/PPA systems may still qualify through 2027, and South Dakota may offer its own incentives — check locally.
