What South Dakota still offers after the federal credit ended
Every incentive on this page is verified against South Dakota government sources - and the expired ones salespeople still quote are called out.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Nunda systems completed in 2026 get $0 from it.
Under South Dakota's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Nunda homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Leased and PPA systems deserve extra scrutiny in 2026: the sales pitch often bundles 'tax savings' that now accrue to the leasing company under separate commercial rules - not to you. Get every claimed saving in writing, attributed to a specific law, before signing a 20-25 year contract.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.

South Dakota rules that decide your payback
| Rule | South Dakota status |
|---|---|
| Export compensation (net metering) | South Dakota has NO net metering — the Public Utilities Commission states plainly that 'South Dakota does not compensate solar generation at a net metered rate'; utilities within the PUC's jurisdiction instead purchase a home system's excess output at avoided-cost rates filed with and approved by the PUC, and residential-scale solar is otherwise unregulated by the commission. |
| State incentive | Renewable Resource Property Valuation Exemption Program (SDCL 10-4-42 to 10-4-45) - property tax exemption of the greater of 70% of the renewable energy property's assessed value or $50,000; solar qualifies, systems under 5 MW, continuous, no application required |
| Sales tax on the system | Not exempt - taxed like any purchase |
| Property tax on added home value | Excluded |
South Dakota's property tax break is partial, not total: only the greater of the first $50,000 of assessed value or 70% of assessed value is exempt, so a large or expensive system can still add taxable value to the home.

What this means for Nunda roofs
Beware of any 2026 payback estimate that looks as good as the 2025 ones: with the federal credit gone, a third of the old subsidy math vanished. If a sales projection has not gotten noticeably worse since 2025, it is hiding something - usually an inflated utility-rate escalation assumption.

Getting Nunda quotes
Marketplace platforms collect bids from multiple SD installers against the same spec, which is the only clean way to compare - same roof, same size, different prices. Getting quotes is free and does not commit you to anything; prices come from the installers, never from this site.

Common questions
How long do solar panels actually last?
Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
Does solar raise my property taxes?
It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.
Is there still a federal solar tax credit in 2026?
No. The 30% Residential Clean Energy Credit was repealed effective for systems placed in service after December 31, 2025, per the IRS. Only systems finished by the end of 2025 qualified. State-level incentives are separate and some survive - check the state page in this guide.
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
How much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
