Sizing formula kW = Annual kWh ÷ (Peak Sun Hours × 365 × 0.82)

Los Angeles homeowners on LADWP have one of the most valuable net metering arrangements left in California in 2026 — full retail-rate credits worth $0.22 to $0.37 per kilowatt-hour that the state’s big three investor-owned utilities cut by 75% three years ago. While Southern California Edison and PG&E customers now receive roughly $0.08 per kWh for solar exports under NEM 3.0, LADWP customers still earn credits pegged to the retail rate they would otherwise pay. That single policy difference changes the entire financial case for residential solar installation in the city of Los Angeles.

If you’re in the LADWP service territory — covering most of the city proper, plus parts of West Hollywood, Culver City, and South Pasadena — you hold an advantage that hundreds of thousands of California solar owners lost when the California Public Utilities Commission approved the Net Billing Tariff on April 15, 2023. Understanding exactly how LADWP’s program works, what a residential solar installation costs in 2026, and how to size your system correctly is how you turn that policy advantage into real dollar savings.

According to EnergySage marketplace data published in April 2026, the average cost of a 10 kW solar system in Los Angeles is $23,771 before incentives, and the average LADWP homeowner is projected to save $176,753 over 25 years. That figure reflects both how high LADWP rates are and how favorably its net metering program credits your production. Here is what every LA homeowner needs to know before signing a solar contract.

LADWP Net Metering in 2026: Why You Are Not Subject to NEM 3.0

NEM 3.0 does not apply to LADWP customers — the most important fact for any Los Angeles homeowner researching solar. NEM 3.0, officially called the Net Billing Tariff, only covers the three major investor-owned utilities in California: PG&E, SCE, and SDG&E. LADWP is a publicly owned municipal utility and sets its own metering policy independently of the California Public Utilities Commission.

Under LADWP’s current net metering rider — which DSIRE (the Database of State Incentives for Renewables & Efficiency) lists as an active program — customers receive bill credits at their applicable retail rate for every kilowatt-hour they send to the grid. Those credits never expire and roll forward month to month against future bills. The only carve-out is that excess credits cannot offset taxes or minimum charges, and any remaining balance at account termination goes back to LADWP rather than being paid out in cash.

By contrast, a homeowner served by SCE just outside the city limits receives around $0.08/kWh for solar exports — a 75% reduction compared to what LADWP customers receive at even Tier 1 rates. According to CPUC proceeding data, battery attachment rates among SCE and PG&E solar customers jumped from roughly 11% before April 2023 to nearly 70% by late 2024, because storage became the only way to capture meaningful value from solar generation under the Net Billing Tariff. LADWP customers can still use the grid as a virtual battery at full credit value, because their export credits are worth as much as the electricity they would otherwise buy back.

There is one legal development worth tracking. The California Supreme Court issued a unanimous ruling in August 2025 ordering a Court of Appeal to reconsider whether NEM 3.0 was approved lawfully. A ruling is expected by mid-2026. Even if that leads to improved export rates for SCE and PG&E customers in the future, it has no direct effect on LADWP’s program, which operates under separate municipal authority. LADWP has not announced any plans to adopt the Net Billing Tariff structure, making the current retail-rate credit arrangement the baseline for all new residential solar interconnection applications in the city. For homeowners considering a new installation, this stability means locking in retail-rate credits for the life of a 25-year system — a meaningful edge over the policy uncertainty facing customers of the state’s investor-owned utilities.

What Residential Solar Installation Costs in Los Angeles in 2026

Solar panel prices in Los Angeles have declined considerably over the past decade, though the city’s higher labor costs keep them slightly above the national average on a per-watt basis. According to EnergySage’s April 2026 marketplace data, the installed cost of a residential solar system in Los Angeles runs approximately $2.37 per watt, putting a 10 kW system at $23,771 before any incentives. SolarReviews data for the same period pegs the California average at $3.14 per watt for a typical 7.2 kW system — around $22,600 total — with the difference largely reflecting system-size variation and installer mix across the state. For a full cost breakdown by state and system size, see our guide to How Much Do Solar Panels Cost in 2026? Complete US. For more on this topic, see our guide to Solar Panels in Wyoming.

A practical rule of thumb for 2026: budget $2.50 to $3.50 per watt installed, with most LA homeowners landing in the $20,000 to $28,000 range for a system sized to cover 100% of their annual usage. Because Los Angeles averages approximately 5.5 to 6 peak sun hours daily — one of the highest figures in the continental U.S. according to NREL’s solar radiation database — your system can be sized somewhat smaller than in cloudier markets and still achieve full annual offset. A 7 kW system is often sufficient for a typical LA household consuming 900 kWh per month.

On the incentive side, the federal solar Investment Tax Credit expired for cash and loan purchases as of December 31, 2025 — a significant shift from recent years when the 30% credit was the primary subsidy. Homeowners who finance through a lease or power purchase agreement may still benefit indirectly, as providers can often pass through the credit in the form of lower monthly rates. California’s Self-Generation Incentive Program (SGIP), administered by the CPUC, continues to offer approximately $150 per kWh of battery storage capacity for general market customers, covering roughly 15% of a typical home battery installation. California law also permanently exempts the added home value from a solar installation from property tax reassessment — meaning a system that raises your appraised value by $20,000 generates zero additional property tax bill.

LADWP Electricity Rates in 2026 and Why They Make the Solar Math Work

One reason the residential solar payback period is so short for LADWP customers is the underlying rate structure. OhmSnap’s 2026 rate analysis — drawing on LADWP’s filed rate ordinances effective January 1, 2026 — puts the baseline residential rate at $0.225 per kWh on average, which is 34% above the national average of $0.168 per kWh reported by the EIA. But that average understates the exposure for heavy users, because LADWP operates a three-tier system where costs escalate sharply with consumption.

Under the standard R-1A schedule, Tier 1 rates for baseline usage ran approximately $0.23 per kWh in early 2026, while Tier 3 rates during summer high-demand months exceeded $0.37 per kWh. Add the City of Los Angeles Electricity Users Tax — 10% applied on top of energy charges — and a household hitting Tier 3 in summer pays effective rates approaching $0.40 per kWh. Every kilowatt-hour your solar panels produce and you consume directly avoids the most expensive electricity on your bill first, which is why even a modestly sized 5 kW system can eliminate hundreds of dollars in monthly charges during peak months.

LADWP rates have been climbing at approximately 4% annually according to OhmSnap’s rate history data. A January–March 2026 adjustment added roughly 2.5 cents per kWh versus the same period in 2025. At 4% annual escalation, a customer paying $0.225 today would face $0.333 per kWh by 2036 and $0.60 per kWh by 2051. Solar panels purchased now lock in your production economics at today’s rates while grid costs continue rising — a hedge that grows more valuable with every annual rate increase.

LADWP also offers a Time-of-Use option under the R-1B schedule, where peak rates during weekday afternoons are higher but off-peak and overnight rates are lower. For solar homeowners who can shift flexible loads — EV charging, dishwashers, laundry — to midday when panels are producing at full output, TOU can increase the self-consumption value of every solar kilowatt-hour generated. The optimal rate plan depends on your specific usage profile and whether you add battery storage to capture evening peak pricing. Use our solar savings calculator to model how LADWP’s 4% annual rate escalation affects your projected savings over a 10-, 15-, and 25-year horizon based on your actual monthly usage.

LADWP vs. SCE Solar Returns: How Much the Utility Difference Is Worth

The zip code on your utility bill matters more than almost anything else when evaluating solar in the greater Los Angeles area. An LADWP customer and an SCE customer living in adjacent neighborhoods face radically different financial outcomes from the same rooftop system — a gap that amounts to tens of thousands of dollars over 25 years.

For LADWP customers, solar without battery storage still performs well because retail-rate net metering means every excess kilowatt-hour is credited at the same rate the customer would pay to buy that electricity back — between $0.22 and $0.37 per kWh depending on tier and season. A homeowner on SCE who installed solar after April 15, 2023 receives around $0.08/kWh for exports under NEM 3.0. That gap translates directly into payback speed: installers in the LADWP territory commonly cite 6 to 7 years to break even, while SCE customers without batteries routinely see payback periods stretch beyond 12 years.

For context across other Sun Belt states: Arizona and Nevada both offer strong solar irradiance comparable to Southern California, but net metering policies vary considerably by utility. In Nevada, NV Energy credits solar exports at a defined avoided-cost rate that sits below retail — closer to NEM 3.0 than to LADWP’s arrangement. Texas has a largely deregulated electricity market with no universal net metering mandate, meaning solar economics depend entirely on the retail electricity provider selected. Hawaii eliminated traditional net metering in 2015 and currently pays around $0.10 to $0.12 per kWh for grid exports — better than NEM 3.0 but still well below LADWP’s retail credit value.

The verdict is clear: LADWP territory offers the strongest solar return in the LA basin without requiring any battery investment. If you are in an SCE zip code, pairing solar with a battery storage system — funded in part by the CPUC’s SGIP rebate of $150 per kWh — is essential to achieve comparable financial results.

Solar Payback Period and 25-Year ROI for LADWP Homeowners in 2026

At current costs and LADWP rates, the residential solar payback calculation in Los Angeles is among the most favorable in the country. A 10 kW system at $23,771 installed generates roughly 14,000 to 15,000 kWh per year in Los Angeles based on NREL’s PVWatts data for the region, given approximately 5.5 peak sun hours daily. At a blended average rate of $0.26 per kWh — the figure EnergySage reports for actual LA electricity costs as of April 2026, reflecting tier usage and the 10% Electricity Users Tax — that production carries a gross annual value of $3,640 to $3,900 in avoided electricity and net metering credits. Payback on the unsubsidized system arrives in approximately 6 to 7 years.

Solar panel degradation averages about 0.5% per year according to NREL research, meaning a panel producing at 100% in year one performs at roughly 87.5% by year 25. This degradation is already baked into most reputable long-term savings projections. At 4% annual rate escalation, the 25-year savings picture is substantial: EnergySage’s marketplace data puts average projected savings at $176,753 over 25 years for LA homeowners — accounting for the upfront system cost, estimated production decline, and compounding rate increases.

Sizing discipline is essential. LADWP’s net metering rules credit excess generation month to month, but any credit balance remaining when you close your account goes to LADWP — there is no cash payout. The Solar Energy Industries Association (SEIA) recommends right-sizing your system to approximately 100% of your 12-month consumption, accounting for planned electrification such as an EV or heat pump before finalizing system size. A homeowner adding a Level 2 EV charger may add 3,000 to 5,000 kWh of annual demand — enough to justify a larger array that would otherwise appear oversized on current bills alone. Getting the size right from the start maximizes every dollar of your investment. Use our solar ROI calculator to input your actual LADWP bill, roof orientation, shading conditions, and planned electrification loads to generate a project-specific payback and 25-year net savings estimate.

Frequently asked questions

Direct answers for US homeowners in California.

Yes. LADWP credits excess solar generation at the same per-kWh rate you pay for grid electricity — your applicable tier rate under R-1A or the time-of-use rate under R-1B. As of 2026, that ranges from roughly $0.22 to $0.37 per kWh depending on usage tier, season, and zone. Credits roll forward indefinitely but cannot offset taxes or minimum charges. Any remaining balance when you close your account is forfeited to LADWP rather than paid out as cash.
