Solar Companies in South Dakota

South Dakota's wide-open plains and clear skies provide about 4.5 peak sun hours daily, giving the Mount Rushmore State solid solar production potential. The state's low population density and lack of a state income tax mean fewer policy mechanisms to incentivize solar, but favorable net metering rules help.

South Dakota mandates net metering at full retail rates for investor-owned utilities including Black Hills Energy and Otter Tail Power. The state provides a property tax exemption for solar equipment and does not charge state income tax, simplifying the solar investment calculation. South Dakota's rural electric cooperatives set their own policies.

Sioux Falls, Rapid City, and Aberdeen are the primary residential solar markets. With moderate electricity rates around $0.12/kWh and no state tax credit (since there's no state income tax), payback periods tend to be 11-14 years, though net metering and the federal credit help make the investment worthwhile.
