Why this number

In Sacramento, an 8 kW system costs about $19,760 installed and generates roughly 11,095 kWh a year (1,541 kWh per kW, PVGIS-NSRDB, less a 10% real-roof derate). Priced on Sacramento’s own utility figures — SMUD at 17.87¢/kWh (export rule not verified with the utility — range shown): 9.8–17.5 years — with the 2026 federal credit at $0. Where exports are paid below retail, figures assume 40% of output is used on-site; the rest is exported at the credited rate. The California state-average model (33.6¢, statewide export rules) would say 10.1 years; the utility math above is the one that matches the bill Sacramento households actually get.

A kilowatt of panels in Sacramento produces about 1,541 kWh a year, placing it 6 of 7 among the California cities modeled here. The state spans Riverside at 1,640 down to Eureka at 1,302, a 26% span, and Sacramento sits inside it at a payback of about 10.1 years.

Only the first two rows differ. Everything financial — rate, tariff, price per watt — is inherited from California 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 Sacramento array would produce, with rates rising at 2.5% a year, comes to roughly $127,374.

Solar aside, the EV vs. gas cost calculator runs Sacramento’s 33.6¢/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.

California is not one solar market

Across the 7 California cities with their own modeled figures, production spans 26% — Eureka at 1,302 kWh per kW to Riverside at 1,640. Every column except production is identical down this table: same 33.6¢/kWh retail rate, same export regime, same $2.47/W installed cost. The payback differences are caused by weather and nothing else.

Your utility, officially

California’s average residential rate is 33.6¢/kWh, but the bill in Sacramento comes from SMUD at 17.87¢ — 47% below the state figure. These are the residential figures Sacramento’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:

Table 3: Solar Cost in Sacramento, CA 2026: ~9.8–17.5-Yr Payback
Utility EIA ID Residential avg price Residential customers Net-metering (residential, self-reported)
SMUD 16534 17.87¢/kWh 592,557 57003 customers / 257.401 MW

One thing we could not verify with SMUD is its export rule, which is why the payback above is a range: ask the utility directly whether you get full-retail net metering or a lower export credit , because that one answer picks your end of the range.

If an EV is in the picture, note that California’s major utilities run the time-of-use tariffs our EV + TOU whole-home calculator ships presets for — worth running before sizing an array, because overnight charging is load daytime solar cannot touch. (And if the EV itself is still hypothetical, check where the EV tax credit stands in 2026 first.)

Sacramento is the other great exception to California solar rules, and the reason is spelled out in SMUD’s full name: Sacramento Municipal Utility District. SMUD is a political subdivision governed by a publicly elected board, not by the California Public Utilities Commission, and it billed 592,557 residential customers at an average of 17.87¢/kWh in the 2024 EIA-861 file. Hold that against the utility that wraps around it on every side — Pacific Gas & Electric, at 31.7¢ — and you get the single most consequential utility fact in the region: crossing from a PG&E suburb into SMUD territory cuts the price of electricity by roughly 44%. People in the Sacramento area genuinely factor this into where they buy houses, and they are not wrong to.

For solar, SMUD’s independence means the CPUC’s Net Billing Tariff (NEM 3.0) does not apply inside the district. SMUD moved past conventional net metering on its own timeline and now takes new solar customers under its own successor, the Solar and Storage Rate, with export compensation set by the SMUD board — not by the CPUC, and not by the statewide NEM 3.0 decision. The official description is at smud.org , and it, not any statewide explainer, is the document that governs a Sacramento rooftop. The district’s own program overview lives under Going Green .

Rate structure is one thing SMUD is unambiguous about: residential service defaults to a time-of-day rate, with a summer evening peak. Cheap off-peak power plus below-retail export credits is a hard combination for solar-only systems — your panels produce into the cheap hours and you buy back through the expensive ones — which is exactly why SMUD’s successor rate is framed around storage. Current schedules are published at SMUD’s residential rates page .

The federal data shows what this environment produces: 57,003 residential net-metering customers and 257.401 MW in 2024 — a large fleet, but with a notably small average system of about 4.5 kW, roughly two-thirds the typical size in Tucson or Phoenix. Cheap retail power shrinks the optimal system: at 17.87¢ there is less bill to attack, and oversizing into a below-retail export credit is money spent buying someone else’s kilowatt-hours. Size to your own load, not to your roof.

Sacramento against the rest of California

Same rate, same export rule, same installed price per watt — only the sunshine changes:

Table 4: Solar Cost in Sacramento, CA 2026: ~9.8–17.5-Yr Payback
City kWh per kW Payback
Riverside 1,640 9.5 years
Los Angeles 1,610 9.7 years
Bakersfield 1,579 9.9 years
San Diego 1,576 9.9 years
Fresno 1,546 10.1 years
Sacramento 1,541 10.1 years
Eureka 1,302 11.9 years

A 26% production span across one state is the reason a single statewide number is only ever a starting point.

What California pays Sacramento for exported power

California does not credit exports at the retail rate, and that rule reaches Sacramento unchanged. The program is Net Billing Tariff (NEM 3.0) , in force since 2023-04-15, crediting surplus power at a published rate of 6.50¢/kWh against a retail rate of 33.6¢.

Export credits come from the CPUC Avoided Cost Calculator , which sets a different price for every hour of every month split weekday/weekend — 576 values a year — so there is no single export rate. Commonly reported annual averages land in the 5-8c band against a retail rate near 34.7c; 6.5c, the midpoint, is used here.

Because a typical home uses only about 40% of its generation as it is produced, most of what a Sacramento array makes is sold at that lower rate. That is why the payback above is 9.8–17.5 years and not the 5.3 years the same hardware would return under full-retail net metering. Raising self-consumption is the lever that closes the gap.

Because the ACC is hourly, your own average depends on when your array actually exports. Evening export is worth far more than midday export.

Sources and method

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 Sacramento in 2026?

About $19,760 for a typical 8 kW system at $2.47 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 California 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 Sacramento?

Roughly 9.8–17.5 years on this model, using Sacramento’s own production figure of 1,541 kWh per kW and its own utility tariff (17.87¢/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 Sacramento better or worse for solar than the rest of California?

Against the state figure, Sacramento is the reference point: our California page uses 1,610 kWh per kW, which is this city. The value of this page is the comparison above, not a different headline number.

Is solar worth it in Sacramento in 2026?

At 33.61¢/kWh and 1,541 kWh per kW, an 8 kW system in Sacramento pays back in about 10.1 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.
