Only the first two rows differ. Everything financial — rate, tariff, price per watt — is inherited from Washington without change, which is the point: a city page that quietly used a different electricity rate from its state page would be guessing, not measuring.
Doing nothing is not free either. Twenty-five years of the electricity an 8 kW Bellingham array would produce, with rates rising at 2.5% a year, comes to roughly $36,959.
Solar aside, the EV vs. gas cost calculator runs Bellingham’s 14.7¢/kWh rate against what a gas car costs to fill instead.
Run it with your own bill
Shared methodology · identical on every city page
- Production figures are unshaded, south-facing, 20° PVGIS values. A real roof — its own pitch, orientation, a tree or a chimney — typically produces 10–25% less; every payback here already carries a 10% real-roof derate.
- Paybacks include $150/yr of running costs and one $2,000 inverter replacement in year 14, which is why they run longer than paybacks quoted elsewhere.
- State export rules cover investor-owned, state-regulated utilities. Municipal utilities and rural electric cooperatives are exempt in most states and set their own terms.
- Installed cost is the state-level EnergySage market figure, not a city quote; a swing of 50¢/W moves payback by roughly a year and a half either way. Get three quotes before trusting any payback — including ours.
Washington is not one solar market
Across the 6 Washington cities with their own modeled figures, production spans 32% — Everett at 999 kWh per kW to Yakima at 1,320. Every column except production is identical down this table: same 14.7¢/kWh retail rate, same export regime, same $2.55/W installed cost. The payback differences are caused by weather and nothing else.
| Location | kWh per kW per year | 8 kW output | Annual value | Payback |
|---|---|---|---|---|
| Yakima | 1,320 | 9,504 kWh | $1,398 | 15.1 yrs |
| Spokane | 1,195 | 8,604 kWh | $1,266 | 16.5 yrs |
| Seattle | 1,086 | 7,819 kWh | $1,150 | 17.9 yrs |
| Tacoma | 1,046 | 7,531 kWh | $1,108 | 18.5 yrs |
| Bellingham (this page) | 1,022 | 7,358 kWh | $1,082 | 18.9 yrs |
| Everett | 999 | 7,193 kWh | $1,058 | 19.2 yrs |
| Washington state average | 1,045 | 7,524 kWh | $1,107 | 18.5 yrs |
Against the state figure, Bellingham runs 2.2% below Washington’s 1,045 kWh per kW — a payback 0.4 years longer than the statewide 18.5-year estimate on the same hardware at the same price.
What sets Bellingham apart
Among the lowest figures in the contiguous US. This far north on the wet side of the Cascades, solar is a long-payback proposition.
Your utility, officially
Washington’s average residential rate is 14.7¢/kWh, and Bellingham’s Puget Sound Energy Inc bills almost exactly that, at 14.63¢. These are the residential figures Bellingham’s utility reported to the U.S. Energy Information Administration on Form EIA-861 for 2024 — computed as revenue ÷ sales from the official file, not estimated:
| Utility | EIA ID | Residential avg price | Residential customers | Net-metering (residential, self-reported) |
|---|---|---|---|---|
| Puget Sound Energy Inc | 15500 | 14.63¢/kWh | 1,091,599 | 23770 customers / 174.867 MW |
How exports are treated matters as much as the headline price: Puget Sound Energy Inc is modeled here under the state’s full-retail net metering rules, and that treatment is baked into every payback figure on this page.
Bellingham breaks the public-power pattern that runs down the I-5 corridor. Seattle has its city department, Tacoma its municipal utility, Everett its county PUD — Bellingham homes are billed by Puget Sound Energy, a private, investor-owned company and the largest utility in Washington, with 1,091,599 residential customers in the 2024 EIA-861 file. Note what that customer count is: PSE’s entire multi-county territory, from the Canadian border down past Olympia, not Bellingham alone. The average residential price across that territory was 14.63¢/kWh — the highest of the five Washington utilities we track, above even Seattle City Light. For solar, that is the one thing working in Bellingham’s favor: production among the weakest in the contiguous-US dataset gets paired with the strongest avoided cost in the state.
Because PSE is investor-owned and regulated by the state commission, the Washington export rules on this page apply to it without the municipal-exemption caveat. And that makes the state-level warning concrete here: RCW 80.60 requires retail-rate crediting, but the statute’s 4% cumulative-capacity threshold has already pushed some Washington utilities onto successor tariffs, and where PSE stands on that line as you read this is exactly what you must confirm. We attempted to verify PSE’s solar program pages directly and could not — pse.com refused our requests from this infrastructure with a geographic security block — so we will not name or characterize its current program. Confirm the export credit rate, the treatment of banked credits, and any annual reset date with PSE itself before signing anything.
What the federal filing does tell us: PSE reported 23,770 residential net-metered customers and 174.87 MW for 2024. That is about one customer in forty-six — the highest adoption share of any Washington utility on this site, ahead of Avista’s one in fifty-six and Tacoma’s one in sixty-five — with an average system around 7.4 kW. It is worth sitting with that: the state’s most expensive power has produced its busiest rooftop-solar market, in a territory that includes some of its cloudiest cities. People respond to the rate, not the sun, in Washington just as they do in New York.
For Bellingham specifically, at 14.63¢ and the page’s modeled 1,022 kWh per kW of annual production, solar is a rate hedge with a very long fuse — real, but only honest when quoted with PSE’s terms attached.

Bellingham against the rest of Washington
Same rate, same export rule, same installed price per watt — only the sunshine changes:
| City | kWh per kW | Payback |
|---|---|---|
| Yakima | 1,320 | 15.1 years |
| Spokane | 1,195 | 16.5 years |
| Seattle | 1,086 | 17.9 years |
| Tacoma | 1,046 | 18.5 years |
| Bellingham | 1,022 | 18.9 years |
| Everett | 999 | 19.2 years |
A 32% production span across one state is the reason a single statewide number is only ever a starting point.
What Washington pays Bellingham for exported power
Washington credits exported power at the retail rate under RCW 80.60 , so a kilowatt-hour a Bellingham array sends to the grid is worth the same as one you buy. That is the best case for solar economics and it is why the payback above is what it is.
It is also the assumption most likely to change. Twenty-two states have already moved to net billing. If Washington did the same on typical terms, this system would take about 30.1 years instead of 18.9 — 11.2 years’ difference from a policy change, with no change to the hardware and none to Bellingham’s weather.
Full retail in statute, but several utilities have hit the 4% cap and moved to successor tariffs, so practice is mixed.
Sources and method
- Production: modeled with PVGIS v5.2 PVcalc (European Commission JRC) using the PVGIS-NSRDB radiation database — the same NREL satellite dataset PVWatts draws on for the Americas. Assumptions: 4 kWp, standard c-Si, 14% system loss, roof mounting, 20-degree tilt, due south, horizon shading on. The 1,022 kWh per kW figure for Bellingham is a modeled location point, not an interpolation from the Washington average. PVGIS is free to use with JRC attribution requested; the underlying NSRDB is public domain (NREL/DOE).
- Real-roof derate: a separate 10% deduction for azimuth, pitch and shading, applied in the shared model rather than folded into the production data — so you can adjust it if your roof is genuinely unobstructed.
- Electricity rate: U.S. Energy Information Administration, average price by state . This is Washington’s residential average; EIA does not publish a Bellingham figure, so the state rate is used and labeled as such.
- Export rules: RCW 80.60 , from our Washington state page and the shared export-rules dataset behind it.
- State average rate: EIA Table 5.6.A, July 2026 data (released Sep 2026), used for every state-average comparison on this page.
- Payback model: shared with the solar savings calculator and the state pages — 2.5%/yr utility inflation, 0.5%/yr degradation, $150/yr running costs, one $2,000 inverter replacement in year 14, federal credit $0. The rest of the toolset — battery, sizing, financing — is under all calculators .
- Incentives: DSIRE . City and utility programs change more often than state ones — check yours directly.
Electricity rate, export regime, production figure and installed cost on this page were last verified on 30 August 2026. Export credits reset on annual tariff cycles and incentive budgets run out mid-year, so treat every figure as a snapshot at that date and confirm current terms before acting. Nothing here is tax or financial advice.
Frequently asked questions
How much do solar panels cost in Bellingham in 2026?
About $20,400 for a typical 8 kW system at $2.55 per watt, before any incentive. With the federal credit at $0 in 2026 that is close to your net cost. Note that the price per watt is a Washington market average — there is no reliable city-level cost data, so treat it as a starting point and get three quotes.
What is the solar payback in Bellingham?
Roughly 18.9 years on this model, using Bellingham’s own production figure of 1,022 kWh per kW and its own utility tariff (14.63¢/kWh) with each utility’s real export treatment. That includes $150 a year of running costs and one inverter replacement, which many published paybacks leave out.
Is Bellingham better or worse for solar than the rest of Washington?
Against the state figure, Bellingham runs 2.2% below Washington’s 1,045 kWh per kW — a payback 0.4 years longer than the statewide 18.5-year estimate on the same hardware at the same price.
Is solar worth it in Bellingham in 2026?
At 14.71¢/kWh and 1,022 kWh per kW, an 8 kW system in Bellingham pays back in about 18.9 years on this model. Treat that as a starting point for reading real quotes rather than as a quote: your roof’s orientation, its shading and the price you are actually offered will move it more than your city does.
How we calculated this
Year-1 saving = production (kW × the city’s modeled kWh per kW) × the blended kWh value (retail rate for self-use, the state export rule for exports). Payback = net cost ÷ year-1 saving, with the federal credit at $0 for 2026 purchases and cost per watt from the state’s installed-price band. Production is modeled from PVGIS/NSRDB irradiance for the city.Sources: U.S. Energy Information Administration (EIA) electricity rates · DSIRE incentive records · public IRS/OBBBA guidance.
