Why solar in Mitchell

System sizing in South Dakota follows a different logic from most states, because the usual anchor is missing. Elsewhere you size against a statutory ceiling, a percentage of consumption, or an annual reconciliation date. Here there is no statewide rule at all, so the only reliable anchor is your own daytime consumption, and that is what a Mitchell design should be built from.

The usual anchors are absent

Kansas caps at 150 percent of average annual consumption. Rhode Island at 125 percent. Nebraska guarantees to 25 kW, North Dakota to 100 kW.

Several states impose an annual reconciliation date at which surplus is forfeited, which effectively caps useful size at your annual usage.

South Dakota has none of that. There is no statewide requirement, so there is no statutory ceiling and no statutory reconciliation to design around.

That sounds like freedom and is closer to the opposite: without an anchor, the design has to be justified from your own consumption rather than against a published rule.

Building from your own consumption

Start with your last twelve months of bills, and ask for your consumption profile through a typical day if your meter provides interval data.

Ask what percentage of your annual usage the proposed system covers, and separately what share of generation the model expects you to consume directly.

Those two numbers together tell you how much of the system output is protected value and how much depends on your utility export policy.

Ask for a smaller system modelled alongside the proposal. Without a statutory floor beneath export value, a smaller and better-matched system carries less risk.

When a larger system is still right

When your utility policy, obtained in writing, credits exports at or near the retail rate. In that case sizing can follow annual consumption as it would elsewhere.

When you have a concrete planned increase in load with a timeline: an electric vehicle, a heat pump, a shop.

When storage is part of the design, since a battery converts export-dependent value into self-consumption value that no policy governs.

What does not justify it is a general expectation of using more electricity later, which in a state without an export guarantee is a bet on two unknowns at once.

What the arithmetic rests on here

The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase in Mitchell receives no federal tax credit, and South Dakota has no state solar tax credit.

Section 48E survives at 30 percent for third-party owners under leases and power purchase agreements, so ask what a provider claims and what reaches you in the rate.

What exists with certainty is the retail value of self-consumed generation, anchored to your own daytime consumption.

Ask for the design built from twelve months of your own bills with the self-consumption share stated and a smaller system shown alongside.

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.

Frequently asked questions

How should I size a solar system in South Dakota?

From your own daytime consumption, since the usual anchors are absent. There is no statutory ceiling, no percentage-of-consumption rule and no statutory reconciliation date to design around.

Is the absence of a cap an advantage?

Closer to the opposite. Without an anchor the design has to be justified from your own consumption rather than against a published rule, and without an export guarantee a larger system carries more risk.

What two numbers should the quote state?

What percentage of your annual usage the system covers, and separately what share of generation the model expects you to consume directly. Together they show how much of the output is protected value.

When is a larger system justified?

When your utility policy in writing credits exports near retail, when there is a concrete planned load increase with a timeline, or when storage converts export-dependent value into self-consumption value.
