California solar in 2026

California is the strangest solar market in the country right now. Electricity costs nearly twice the national average, which should make this an easy call. But the state also pays less for your exported power than almost anywhere, the federal credit is gone, and a property tax deadline lands January 1, 2027. Whether solar pencils here depends on when your panels produce and when you use power, not just how much you pay per month.

California homeowners pay an average of 33.25 cents per kWh (May 2026, EIA) against a US average of 18.44. New solar connects under the Net Billing Tariff, which credits exports at their hourly grid value instead of the retail rate. There is no California income tax credit for solar. Systems that qualify before January 1, 2027 keep a property tax exclusion that new installs lose after that date. Batteries change the math more here than in any other state we cover.

What the big three utilities charge

Almost every California homeowner buys power from PG&E, SCE, or SDG&E, and their prices have split apart. SDG&E customers absorbed an 11.4 percent increase in January 2026 and another bump in April. SCE actually drifted down. PG&E sits in between, high and slowly falling. Statewide, the average worked out to 33.25 cents in May 2026, basically flat against a year earlier.

UtilityAverage residential rateDirection in 2026
PG&E41.46 c/kWh (Jan 2026 advisory)Down from 44.36 c/kWh in September 2025
SCE34.4 c/kWh (June 2026 advisory)Roughly flat, 33.2 c/kWh counting the Climate Credit
SDG&E46.4 c/kWh (April 2026)Up 11.4 percent in January, another 1.5 percent in April
Statewide average (EIA)33.25 c/kWhFlat vs 33.29 c/kWh in May 2025

Net billing is not net metering, and the difference is money

Every system connected since April 15, 2023 falls under the Net Billing Tariff from CPUC Decision D.22-12-056. The utilities market it as the Solar Billing Plan. The mechanics matter: your exports earn what the grid thinks that hour of power is worth, set by an avoided cost model, not the retail rate you pay. On a sunny March afternoon, when every roof in the state is exporting, that value is low. The retail rate you avoid by using your own power stays high. So the game in California is self consumption: batteries, load shifting, and sizing the system to your actual daytime use.

One piece of the export rate is published and locked: a bonus credit paid on top of the hourly value for nine years, set by the year you connect. It is shrinking on a schedule.

Interconnection yearBonus per exported kWhLow income bonus
2024$0.018$0.072
2025$0.013$0.054
2026 (now)$0.009$0.036
2027 (final year)$0.004$0.018

Source: PG&E Solar Billing Plan toolkit, residential Energy Export Bonus Credit, locked for nine years from interconnection. The bonus program ends after 2027. The underlying hourly export values vary by hour and season and are not published as a single average, so be suspicious of any pitch quoting one flat "NEM 3.0 rate."

The incentive picture, including the deadline

California never had a state solar income tax credit, and the 30 percent federal credit died for purchases after December 31, 2025. What the state still has is narrower and has a clock on it.

ItemWhat it doesStatus
Property tax exclusionSolar is excluded from new construction assessment, so your property taxes do not rise from the installEnds for new systems January 1, 2027. Systems qualifying before that date keep it until the home changes hands (California BOE)
SGIP battery rebateStorage rebates through the CPUC, equity tier listed at $850 per kWhCPUC page says available; industry sources say general market budgets are thin. Confirm current funding with your installer before counting on it (CPUC SGIP)
State income tax creditDoes not exist in CaliforniaNothing to claim. Any pitch that implies one is wrong
Federal 48E (lease/PPA only)Provider claims it, prices some into your rateAlive for third party owned systems (CRS)

The practical read: if you are buying in California, the 2027 property tax deadline is the only date that should hurry you. Everything else rewards patience and careful sizing. A system qualifying in 2026 keeps its exclusion for as long as you own the home. The same system installed thirteen months later gets assessed as new construction, every year, forever.

Production: the sun is not the problem

We ran the PVGIS model ourselves for five California cities on August 17, 2026, same assumptions everywhere: south facing, 30 degree tilt, 14 percent losses. The surprise is San Diego at the bottom. The marine layer is real, and the sunniest reputation in the state belongs to a city that produces 9 percent less than Los Angeles.

CitykWh per kW per yearAnnual output, 9 kW system
Los Angeles1,70515,345 kWh
San Jose1,66014,940 kWh
Fresno1,64714,823 kWh
Sacramento1,64614,814 kWh
San Diego1,54813,932 kWh

Method: PVGIS v5.2, NSRDB radiation database, model runs by Solar Learning Lab, August 17, 2026. We use a 9 kW example because the average California system is 8.95 kW per EnergySage, smaller than the national norm since usage per home here is low.

Run your own numbers

California installs are cheap per watt ($2.46/W cash median per EnergySage) and the retail rate you offset is enormous. That is why EnergySage pegs average payback at 7.39 years, the fastest of any state we cover, even with net billing dragging on export value. Treat the output below as a self consumption estimate and remember exports earn less here.

The provider keeps the federal 48E business credit and prices some of it into your rate. In 2026 this is the only path that captures any federal incentive.

Estimates, not quotes. Inputs use the California average rate from EIA (Table 5.6.A, May 2026), our own PVGIS production runs, and EnergySage August 2026 cost data. Under the Net Billing Tariff your export credits depend on hourly values we cannot model here, so treat the bill offset as approximate. We are a solar installer and we also partner with other solar companies. See our disclosures.

What changed in the last year

  • SDG&E rates jumped 11.4 percent in January 2026, then another 1.5 percent in April (SDG&E January alert). San Diego is now the strongest solar case in the state on rates alone, despite the weakest production in our table.
  • The export bonus credit stepped down again for 2026 interconnections, to $0.009 per kWh, and ends entirely after 2027 (PG&E toolkit).
  • SB 710 confirmed the property tax exclusion mechanics: qualify before January 1, 2027 and you keep it until the property changes ownership (BOE legislative analysis).
  • AB 942, the bill that would have shortened legacy net metering protections, was amended in the Senate to protect existing NEM contracts when a home sells (CALSSA). We have not confirmed its final enacted status from the legislature's own site, so do not treat it as settled law either way.

Who actually installs well in California

California's installer market is the country's largest and its churn since the NEM 3.0 transition has been brutal, so recency matters more than brand recognition. Our ratings pass centers on greater Los Angeles, where the CSLB contractor pool is deepest. Every company below holds a current Google rating of 4.7 or better. Ask each bidder how many net billing systems they have commissioned since 2023; an installer still pitching NEM 2 payback curves is reading from an old script.

Go deeper: Los Angeles

Everything above describes Edison, PG&E and SDG&E territory. Los Angeles runs on municipal LADWP power and still credits solar exports at full retail, a deal the rest of the state lost in 2023. We built a dedicated guide with LADWP's tiered rate table, express permit rules and a month by month production curve for an LA roof: Los Angeles solar in 2026.
