What Washington pays for your exported solar power
Export compensation is the single biggest payback lever in 2026. Here is Washington's current rule in plain words, with the official source.
Under Washington's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Granger homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Granger, Washington has about 3,789 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
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.
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.
The 2026 numbers
| System size | Installed price (marketplace avg) | Notes |
|---|---|---|
| 6 kW | $15,480 | Small roof / low usage |
| 8 kW | $20,640 | Typical starter system |
| 10 kW | $25,800 | Family home with AC |
| 12 kW | $30,960 | Large home / EV charging |
| Home battery (optional) | $12,000-$16,000 | Backup power + self-consumption |

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 Granger roofs
The honest 2026 answer for Granger: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is Washington's export compensation, covered in the net metering section.

Getting Granger quotes
Before requesting quotes, have your last 12 months of electricity bills handy - system sizing should follow your real usage, not a salesperson's template. A bid sized far above your usage is a margin play, especially now that surplus export pays less in most states.

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.
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.
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.
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.
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.
