Home Solar Cost Guide

What Wisconsin still offers after the federal credit ended

Every incentive on this page is verified against Wisconsin 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 - Dallas systems completed in 2026 get $0 from it.

Under Wisconsin's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.

Installed home solar for Dallas 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The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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.

Wisconsin rules that decide your payback

RuleWisconsin status
Export compensation (net metering)Wisconsin has no single statewide net-metering rate — net metering is offered to investor-owned and municipal utility customers below a size threshold set by each utility, and every utility files its own PSC-approved parallel-generation tariff with its own "buyback rate" for excess electricity, so the size limit and the export credit vary substantially from one utility to the next.
State incentiveFocus on Energy Residential Solar Reward - $600 per kW up to $2,400 for systems installed in 2026
Sales tax on the systemExempt
Property tax on added home valueExcluded

Because each utility writes its own buyback tariff, two Wisconsin homeowners with identical systems can be paid very different rates for the same exported kilowatt-hour; the PSC page describes net metering as available to investor-owned and municipal utility customers, and does not extend it to rural electric cooperative members. The property-tax exemption also excludes purely passive solar design and any component that would have been present in a conventional energy system, and an assessor may require Form PR-303 to grant it.

What this means for Dallas 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 Dallas quotes

Same-day contracts are a red flag in this industry. Legitimate WI installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.

Common questions

How do I check if a solar quote is fair?

Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.

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.

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.

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.

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.
