South Dakota has no state income tax (applies to ITC benefit calculation), but no state solar credit either. Low electricity rates mean payback is 10–12 years.
What solar incentives are available in South Dakota?
South Dakota homeowners can stack multiple incentives: the state solar incentives (federal ITC expired Dec 2025) (ITC) — $6,480 on a typical 8 kW system; a property tax exemption (solar-added home value not taxed); and net metering through Black Hills Energy / Xcel Energy SD.

  2. 2
    Review your electricity bill

    Your last 12 months of usage determines the right system size. At 13.6¢/kWh in South Dakota, a system that offsets 90% of your bill hits the best cost-per-kWh sweet spot.
