Is there still a solar tax credit for Kirkland homeowners in 2026?
The 30% federal credit is gone for 2026 installations. What survives for Kirkland: Washington's own incentives and tax treatment - verified against state sources.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Kirkland systems completed in 2026 get $0 from it.
Installed home solar for Kirkland homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Kirkland, Washington has about 95,499 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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.
If a salesperson in Kirkland tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Washington's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.

The 30% federal tax credit is gone for 2026 installations
The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts the installation completion date, not the contract date.
Washington rules that decide your payback
| Rule | Washington status |
|---|---|
| Export compensation (net metering) | Washington utilities must offer net metering at retail rate (excess kWh credited forward on the next bill) for systems up to 100 kW, but only until the earlier of June 30, 2029 or the date a utility's cumulative net-metered capacity reaches 4% of its 1996 peak demand — a threshold several utilities have already crossed, after which they may offer less than retail rate. |
| State incentive | Sales and use tax exemption on purchases and installation of solar energy systems (RCW 82.08.962 / 82.12.962) — a 100% exemption, taken at the point of sale, for systems generating at least 1 kW and no more than 100 kW AC, including installation labor |
| Sales tax on the system | Exempt |
| Property tax on added home value | No exclusion on record |
Retail-rate net metering is not guaranteed for the life of your system: several Washington utilities have already hit the 4%-of-1996-peak-demand cap and may set their own export terms, and the statewide obligation ends June 30, 2029 regardless — so confirm your specific utility's current tariff before signing a contract.

What this means for Kirkland roofs
Whether solar still pays in Washington after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.

Getting Kirkland quotes
The spread between the highest and lowest bid for the same roof routinely hits 30-50%, because solar quotes carry very different sales overheads. Two or three independent bids collected against the same system size is the single highest-value hour in the whole project.

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.
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
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 solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
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.
