Typical home: Worth it

Is solar worth it in California?

For a typical California home in 2026, solar is worth it: about a 10.9-year payback and $21,593 saved over 25 years after paying for the system. Check your own home, because roofs, usage and utilities vary a lot.

Why it comes out this way

  • Electricity is expensive: 33.0¢ per kWh over the last 12 months, 83% above the U.S. average (18.0¢).
  • Exported solar is typically credited at about 12% of retail, so systems pay best when sized for what you use yourself.
  • A typical system here produces about 1,658 kWh per kW per year (ranked #4 of 51).
  • There is no federal tax credit for homeowners who buy in 2026, which adds several years to payback compared with 2025.
Watch out for leases right now. Lease and PPA providers can still claim a federal credit that homeowners can't, so they're being pushed hard. Compare any lease against buying with our lease vs. buy calculator.

Net metering and export rules in California

Net billing (reduced export credit). New customers of PG&E, SCE and SDG&E are on the Net Billing Tariff (often called NEM 3.0): solar you use at home saves the full retail rate, but power you send to the grid is credited at hourly 'avoided cost' values that average only about 4-5 cents/kWh (higher on summer evenings). Batteries greatly improve the economics. Municipal utilities like LADWP and SMUD set their own rules.

Exports valued hourly using the CPUC Avoided Cost Calculator (ACC), varying by month/hour and locked for 9 years for the customer's vintage; early tranches also receive an 'ACC Plus' adder. 2024 ACC averages for 2025/2026 applicants: PG&E ~3.9, SCE ~4.6, SDG&E ~3.7 cents/kWh (adders ~1 cent PG&E, ~2 cents SCE for 2026 applicants).

  • Netting: instantaneous
  • Unused credits: Dollar export credits roll forward month to month; annual true-up after 12 months. Remaining credit at true-up is cashed out at Net Surplus Compensation rate (wholesale, a few cents/kWh) only for net kWh surplus.
  • System size limit: 1000 kW
  • Fixed charges: Income-graduated Base Services Charge on all IOU residential bills (~$24.15/month standard, ~$12 FERA, ~$6 CARE), implemented late 2025 (SCE, SDG&E) and March 2026 (PG&E), with lower per-kWh rates. NBT customers must take an electrification TOU rate (e.g., PG&E E-ELEC, SCE TOU-D-PRIME, SDG&E EV-TOU-5). Legacy NEM 2.0 customers pay non-bypassable charges on imports.
  • Last major change: Net Billing Tariff (CPUC D.22-12-056) effective Apr 15, 2023. Court of Appeal upheld NBT on remand March 2026; CA Supreme Court denied review June 10, 2026. Base Services Charge 2025-2026.
  • Pending: AB 942 (2025) amended to preserve legacy NEM on home sale; final status not confirmed. CPUC ACC updates (biennial) change export values for new vintages.

What solar costs in California

A fair cash price is around $2.90 per watt before incentives. For the 3 kW system that fits a typical home, expect roughly $7,400 to $10,400; smaller systems cost more per watt.

Public installation records (LBNL Tracking the Sun and state data, 217,063 owned systems since 2024) show a median of $4.51/W, with the middle half between $3.24 and $5.92. These prices include loan dealer fees, which is why cash quotes are often lower.

Protect yourself when buying

  • Check the license. CSLB C-46 (Solar) or C-10 (Electrical) contractor license; B general contractors in limited cases. Look up an installer
  • Cancellation rights. 3 business days to cancel many home-solicitation sales. Solar Energy System Disclosure Document (CPUC, required for IOU customers since 2018 under AB 1070); CSLB Solar Energy System Disclosure; Civ. Code 1689.6 home solicitation 3 business days; AB 2471 (2020) extends to 5 business days for buyers 65+ and bars starting work during the period. How to cancel
  • HOA and solar access. Yes. California Solar Rights Act (Civil Code 714, 714.1) prohibits HOAs and local rules from unreasonably restricting solar.
  • Community solar. Limited: IOU Community Solar Green Tariff and DAC-Green Tariff; a broader program under AB 2316 was adopted by the CPUC in 2024 in a form critics call unworkable.

More about solar in CaliforniaUnder NBT, export value is so low that batteries and high self-consumption are key; an hourly model using ACC values is far more accurate than a flat cents/kWh. Retail rates are very high (PG&E ~35-45 cents/kWh on TOU), so self-consumed solar is valuable. Base Services Charge cannot be offset by solar. Federal 25D ended after 2025; third-party-owned (lease/PPA) systems may still benefit from commercial credits.
