Sioux FallsSolar Incentives 2026: Rebates, Tax Credits & Net Metering
Sioux Falls homeowners stack the 30% federal tax credit and Xcel Energy net metering. At 4.6 peak sun hours a day, a home with a $110/month bill (about 786 kWh) needs roughly a 7.1 kW system — 18 panels — and pays back in about 9.8 years.
Solar Incentives Available in Sioux Falls
Solar incentives in Sioux Falls come in three layers. First, every homeowner qualifies for the 30% federal Residential Clean Energy Credit on the full installed cost, claimed on IRS Form 5695. South Dakota does not add a state income tax credit, so the federal credit is the main up-front incentive. Third, Xcel Energy sets the local rules for crediting the solar power you export.
Xcel Energy offers net metering in Sioux Falls, and South Dakota exempts the added value of solar from property tax.
