Solar Panel Cost in South Dakota (2026)

Net metering: 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.
