  • There is no statewide general contractor license. The wiring must be done under a licensed South Dakota electrical contractor. The Electrical Commission verifies licenses by phone (605.773.3573) or email.

Monthly charges
Published charges run from $1.33 a month at Otter Tail Power to $20.00 a month at MidAmerican Energy. Xcel Energy pays for no more than 2,000 kWh a month.
Property tax
The first $50,000 of a solar system's assessed value, or 70% of it if that is more, is free of property tax. There is no form to file.

Sioux Valley Energy credits 1.61 cents per kWh. Missouri River Energy Services, supplier to Brookings, Pierre and Watertown, filed 3.45 cents per kWh for 2026.

Federal credit

What to check with your utility

Xcel Energy

  • Pays 3.16 cents per kWh for extra power (Rate Code E50), since January 1, 2026.
  • A metering charge of $3.75 a month; extra power above 2,000 kWh a month earns nothing.
  • Asks for a service agreement of at least 12 months and liability insurance of at least $300,000 per occurrence.

Black Hills Energy

  • Pays 2.48 cents per kWh (Schedule 3), unchanged since August 1, 2019: the lowest of the six regulated utilities.
  • Charges for the extra meter, but the rate sheet gives no amount. Ask for it.
  • A rate case filed February 19, 2026 (Docket EL26-003) was still open. Ask if Schedule 3 changes.

NorthWestern Energy

  • Pays 2.547 cents per kWh (Rate No. 73), since April 1, 2025.
  • A customer charge of $2.00 a month and a 12-month minimum agreement.
  • Do not count on the $4.29 per kW capacity payment; it needs 65% of full power in summer peak hours.

Otter Tail Power

  • Pays 4.871 cents per kWh (Section 12.01): 4.571 cents for the power plus 0.3 cents for the REC, which goes to Otter Tail.
  • A customer charge of $1.33 a month; prices for bills from April 1, 2026.
  • A time-of-day option (Section 12.02) also exists. Ask which one your agreement uses.

MidAmerican Energy and Montana-Dakota Utilities

  • MidAmerican pays 2.26 to 4.61 cents per kWh by season and hour, since August 15, 2026, and charges $20.00 a month.
  • Montana-Dakota pays 3.416 cents per kWh (Rate 95) since January 1, 2026, with a metering charge of 7 cents a day.

Sioux Valley Energy and other co-ops

  • Co-ops and city utilities set their own terms; the PUC does not approve their prices.
  • Sioux Valley Energy credits 1.61 cents per kWh from February 2026 bills. Get your co-op's terms in writing.

Check the company and its warranty

Three names can appear in one solar deal: the company that sells, the company that signs the contract and the licensed people who do the work. Check that they fit together.

  • Contract company: look up its license on the South Dakota Electrical Commission electrical contractor license (South Dakota has no statewide general contractor license). The name must match your contract.
  • Electrical connection: Wiring a solar system into a home is electrical work that must be done under a licensed South Dakota electrical contractor; the only exception is an owner wiring their own owner-occupied home or farmstead under a homeowner permit (https://dlr.sd.gov/electrical/homeowner_wiring.aspx). Ask who does it.
  • Warranty documents: ask for the workmanship warranty, the roof coverage terms and each equipment warranty before you sign.

Before your first sales call, read questions to ask your solar installer and how to read a solar quote.

Compare your South Dakota quotes

Ask every company to quote the same basics. Then the differences you see are real.

The boxes are for your own use. Nothing is saved or sent.

From quote to permission to operate

Some steps overlap, and timing depends on your town, your utility and equipment supply. Ask each installer for a written schedule for your project.

  1. Proposal and site check

    The installer looks at your roof, shading and electrical panel and gives you a written proposal.

    You and the installer
  2. Design and applications

    After you sign, the installer finishes the design and applies to your utility for the connection.

    Installer; you sign the forms
  3. Permits and utility review

    Your town or county reviews the building and electrical permits. The utility reviews the connection.

    Permit office and utility
  4. Installation and inspection

    The crew installs the system. A licensed electrician connects it, and the inspector checks the work.

    Installer crew, electrician and inspector
  5. Permission to operate

    The utility approves the system and updates your meter if needed. Turn the system on only after this step.

How we rate South Dakota solar companies

Each company gets up to 100 points from facts anyone can check: its own website and South Dakota’s public license records, read October 14, 2026. Facts a company does not publish earn no points. We could not check South Dakota’s license records for these companies yet, so none of them gets points for a checked state license. No company pays for its rating, and we do not use customer star reviews.

  • Licensing (30 points): an active state license, a licensed electrician and license numbers printed on its website.
  • Warranty protection (35 points): workmanship warranty length, roof-penetration coverage in writing and any production guarantee.
  • Local presence (15 points): an office in South Dakota and South Dakota named as a service area.
  • Track record (10 points): years installing solar.
  • Options (10 points): batteries and the number of ways to pay.

Stars: 85 points or more is 5 (Top-rated), 72 is 4.5 (Excellent), 60 is 4 (Very good), 45 is 3.5 (Good), below 45 is 3 (Average). We did not inspect installations, collect customer quotes or test customer service.

South Dakota solar company FAQs

How do I check a South Dakota solar installer?

Ask for the company’s South Dakota electrical contractor license number and confirm it with the Electrical Commission, by phone at 605.773.3573 or by email. The state has no general contractor license, so the electrical license is the key check. Then read the written workmanship warranty and ask who files the utility agreement.

Does South Dakota have net metering?

No. The Public Utilities Commission says the state does not pay for solar at a net metered rate. Regulated utilities buy extra power at their own filed prices, from 2.48 cents per kWh at Black Hills Energy to 4.871 cents at Otter Tail Power. Co-ops and city utilities set their own terms.

Is there a South Dakota solar tax credit or rebate?

No. South Dakota has no state income tax, so there is no state tax credit, and we found no state rebate. The federal credit ended for home systems finished after December 31, 2025. The one state benefit is a property tax exemption on the first $50,000 of the system’s assessed value, or 70%.

Can I lease solar panels in South Dakota?

Yes, if the lease gives you all rights to operate, maintain and control the system, the Public Utilities Commission says. A company cannot sell you the power by the kWh, because only your assigned utility may sell electricity at retail. Compare a lease’s total cost with a cash or loan quote before you sign.

Will the companies on this page contact me?

Not because they appear here. This page is an editorial comparison. If you request quotes, the providers that serve your area may contact you. They can include installers, marketplaces and lead exchanges. Our page on how we make money explains how EcoGen is paid.
