Tax credit
#01
Federal Residential Clean Energy Credit (Section 25D) - ENDED
The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025. Cash and loan purchases made now receive no federal tax credit, and South Dakota has no state solar tax credit to fall back on.

#02
Federal Commercial ITC (Section 48E) - via Lease / PPA
Section 48E, the commercial Clean Electricity Investment Credit, survives at 30 percent and is available to third-party owners of residential systems under leases and power purchase agreements. The provider claims it and may reflect part of the value in the rate offered. Ask what they claim and what actually reaches you, and confirm with a tax advisor.
Source ↗ Net metering
#03
No statewide net metering requirement
South Dakota does not have a statewide net metering requirement, which puts it in a very small group of states. Utilities may offer customer generation arrangements voluntarily, and some do, but there is no statutory obligation and therefore no floor beneath what any utility offers. That makes a written statement from your own utility the necessary starting point for any South Dakota solar project, rather than something to confirm later.
Program
#04
No South Dakota state solar tax credit
South Dakota does not offer a state income tax credit for residential solar, and levies no personal income tax in any case. With the federal residential credit expired for property placed in service after December 31, 2025, a cash or loan purchase now receives no tax credit at either level. Ask your county director of equalization how residential solar is treated for property assessment at your address, since that is administered locally.
Utility
#05
Everything depends on your own utility
South Dakota is served by Black Hills Energy and NorthWestern Energy alongside rural electric cooperatives and municipal utilities. Without a statewide requirement, each sets its own approach to customer generation from scratch. Whether exports are credited at all, at what rate, on what netting basis, and what interconnection costs are all determined by your own utility, and there is no default to fall back on.
Net metering · South Dakota
No statewide requirement; entirely utility-by-utility
South Dakota does not have a statewide net metering requirement, and that is unusual enough to change how you should approach a solar project here. In almost every other state, statute or a regulator establishes a floor: net metering must be offered, at least up to some system size, and the argument is about how generously exports are compensated above that floor. Nebraska guarantees it to 25 kW, North Dakota to 100 kW, Kansas requires it of its investor-owned utilities. South Dakota does not. Utilities may offer customer generation arrangements voluntarily, and some do, but nothing obliges them to and nothing constrains the terms if they do. The practical consequence is that the first step in a South Dakota solar project is not comparing quotes. It is obtaining, in writing, from the utility that bills your address, a statement of what it will do with electricity your system exports: whether it credits it at all, at what rate, whether generation is netted across a billing period, whether credits carry forward or expire, what the interconnection process involves and costs, and whether any charge applies to customer generators. Only once you have that document does a quote mean anything, because until then the largest variable in the calculation is unknown. It also means the value of self-consumption is unusually clear here: electricity you use at the moment it is generated offsets a purchase at the full retail rate under any arrangement, whatever your utility does or does not do about exports.
Worth checking before you sign:
taking a rebate can change your net-metering terms, and export credit rules
differ by utility. Your matched installer confirms the exact numbers for
your address.
