Solar Panel Installation in Rapid City FAQs
Is solar worth it in Rapid City?
The sun is strong (about 1,240 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the South Dakota incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. South Dakota has no state solar income tax credit that we found, but it exempts the first $50,000 or 70 percent of the assessed value of a renewable energy system from real property tax.
Do I need a permit for solar panels in Rapid City?
Usually yes, and the utility may need to approve solar and batteries. Building Services, Community Development Department (City of Rapid City) handles permits in Rapid City; see the permit information above.
