Solar panels in Los Angeles cost roughly $2.50 to $3.50 per watt installed in 2026. For a typical 8 kW home system, that is about $20,000 to $28,000 before a battery. The bigger question is not the sticker price. It is which utility serves your address, because LADWP and SCE value the same system very differently.
This guide shows what solar costs in Los Angeles by system size, what pushes your quote up or down, how payback differs between LADWP and SCE, and how to get an itemized estimate you can actually compare.
Quick Answer: Solar Cost in Los Angeles in 2026
| Item | Typical range |
|---|---|
| Price per watt (installed) | About $2.50 to $3.50 |
| Average LA system size | About 9 to 10 kW |
| Typical 8 kW system, before battery | About $20,000 to $28,000 |
| Battery add-on (for example, a Powerwall 3) | About $10,000 to $16,000 |
| Federal tax credit for cash or loan purchases | None, ended December 31, 2025 |
| Typical payback, LADWP, panels only | Roughly 7 to 9 years |
| Typical payback, SCE, panels only | Roughly 10 to 13 years |
These are ranges from published 2026 market data, not quotes. Roof type, panel age, and permit office all move the real number.
Solar Installation Cost in Los Angeles by System Size
Larger systems cost less per watt, but the total is higher. Here is what the 2026 range looks like at $2.50 to $3.50 per watt.
| System size | Typical LA fit | Estimated installed cost (before battery) |
|---|---|---|
| 5 kW | Small home or condo with low usage | $12,500 to $17,500 |
| 6 kW | Bungalow with modest usage | $15,000 to $21,000 |
| 8 kW | Typical single-family home | $20,000 to $28,000 |
| 10 kW | Larger home with central air | $25,000 to $35,000 |
| 13 kW | High usage, EV, or all-electric home | $32,500 to $45,500 |
EnergySage’s September 2026 marketplace data puts the Los Angeles average at about $24,432 for a 9.76 kW system ($2.50 per watt), with prices ranging from about $20,800 to $28,100. Other sources publish higher averages near $3.14 per watt, which is why an itemized quote matters more than any single headline number.
Why LA Systems Run Larger Than the State Average
Los Angeles households often use more air conditioning, more appliances, and increasingly EV chargers. A home spending $300 or more per month on electricity usually needs an 8 to 10 kW system to make a real dent in the bill. If you plan to add an EV, see how solar and an EV charger savings add up before sizing.
LADWP vs SCE: Same Price, Different Value
Los Angeles County is split between utilities, and the rules that value your solar depend on which one is on your bill.
| Factor | LADWP (City of Los Angeles) | SCE (Long Beach, Torrance, Santa Clarita, most county cities) |
|---|---|---|
| Governing rule | LADWP’s own net energy metering program | CPUC NEM 3.0 net billing tariff |
| Value of exported solar | Credited close to your rate schedule’s energy price and netted over the billing period | Low avoided cost credit, roughly 75 percent below the old retail credit on average |
| Is a battery needed for strong savings? | Optional, a choice for evenings and backup | Effectively yes |
| Peak period to design around | Weekday afternoons on the optional time-of-use plan | 4 PM to 9 PM every day on time-of-use plans |
| Typical payback, panels only | Roughly 7 to 9 years | Roughly 10 to 13 years |
Payback ranges are illustrative projections from published models, not guarantees. Your usage and rate plan set the real result.
Not sure which utility you have? Check the top of your electric bill. Pasadena, Glendale, and Burbank run their own municipal utilities with separate rules. Pasadena homeowners can see the PWP solar rebate claim steps, and LADWP customers can review LADWP solar and battery costs.

What Makes Your Los Angeles Solar Estimate Go Up or Down
| Factor | Effect on cost | What to check |
|---|---|---|
| Roof material | Tile and flat roofs cost more to work on than composition shingles | Ask for the roof type to be listed in the quote |
| Main electrical panel | Older LA homes with 100 amp panels often need an upgrade | Ask if a panel upgrade is included or extra |
| Roof condition | A roof near the end of its life should be replaced before panels go on | See whether your roof is too old for solar |
| Shading and orientation | Affects how many panels fit and how much they produce | Ask for a production estimate that accounts for shade |
| Panel brand | Tier 1 panels such as QCells cost more upfront and hold up better over time | Ask for make and model, not a category name |
| Inverter type | Microinverters cost more but help on partly shaded roofs | Ask which type is quoted |
| Battery | Adds thousands, but changes savings most on SCE | Get quotes with and without |
| Permit office and interconnection | Timelines and fees differ by city | Ask who handles the permit and utility approval |
Roof Condition, Orientation, and Shading
South-facing roofs produce the most per panel in Los Angeles. West-facing roofs are a close second and can actually help SCE customers under NEM 3.0, since afternoon production lines up better with peak rate hours.
What a Complete Solar Estimate Should Include
A trustworthy estimate is not a single number. Look for these lines shown separately:
- System size in kW
- Panel brand and model
- Inverter type
- Battery option, with or without
- Electrical panel upgrade, if needed
- Permit and interconnection costs
- Warranty terms
If a company gives one total with no breakdown, you cannot compare it fairly with another quote.
Solar Battery Cost in Los Angeles
Under NEM 3.0, a battery is what turns midday solar into high-value evening savings for SCE customers. Under LADWP’s program, panels alone still make financial sense, and a battery is more about backup power and evening use.
| Scenario | Battery worth adding? |
|---|---|
| SCE customer, solar-only quote | Get a quote with a battery. The gap between export credit and evening prices is large |
| LADWP customer on the standard rate | Optional, mainly for backup power |
| LADWP customer on time-of-use | Can help cover evening rates after panels wind down |
| Frequent outages or wildfire shutoffs | Worth pricing for backup value alone |
Expect roughly $10,000 to $16,000 for a battery such as a Powerwall 3, depending on configuration and plan. See what a solar battery costs for a full breakdown, or use the solar, battery, and EV charger estimator to price them together.
Federal Tax Credit and Financing in 2026
The 30 percent federal residential solar tax credit ended for cash and loan purchases of systems placed in service after December 31, 2025. Many older cost guides still include it in their numbers, so be careful when comparing.
| Option | How it works in 2026 |
|---|---|
| Cash | You own the system and get no federal credit |
| Loan | You own the system and get no federal credit, but you spread the cost |
| Lease, PPA, or prepaid | The provider owns the system and may pass along the value of a commercial tax credit as lower pricing |
Compare terms in writing before you decide. See solar lease vs loan in California and the 2026 solar incentives guide for what is still available.
What Payback Looks Like in Los Angeles
Payback depends on your utility, system size, usage, and whether you add a battery. Published 2026 models suggest:
- LADWP, panels only: roughly 7 to 9 years
- SCE, panels only: roughly 10 to 13 years
- SCE, with a battery: often shorter than panels only, since the battery captures the expensive evening window
- EnergySage marketplace average for Los Angeles: about 5.8 years, based on quote data
Panels are built to last 25 years or more, so even a 10-year payback leaves well over a decade of low-cost power. Rising utility rates usually shorten payback further. Use the payback period guide and the solar calculator to run your own numbers.
How Axia Estimate Gives You Real Numbers
Axia Estimate is powered by US Power, a factory-direct representative of QCells.
- Factory-direct QCells pricing that typically runs 15 to 20 percent below market rate
- 25-year comprehensive warranty on panels, workmanship, and performance
- CSLB licensed consultants who explain each line of the estimate
- Estimates based on your address, utility, and bill, not a national average
What to Check Before Requesting Your Solar Estimate
- Roof age: if it is more than 15 years old or worn, plan for a possible replacement.
- Shade: note any shading between 9 AM and 3 PM.
- Roof obstacles: skylights, HVAC units, and chimneys reduce usable space.
- Your bills: pull the last 12 months, since summer and winter usage differ in Los Angeles.
- Your utility: LADWP or SCE, listed at the top of your bill.

Frequently Asked Questions About Solar Cost in Los Angeles
How much does solar cost in Los Angeles in 2026?
Roughly $2.50 to $3.50 per watt installed, or about $20,000 to $28,000 for a typical 8 kW system before a battery. Smaller 5 to 6 kW systems run about $12,500 to $21,000, and larger 10 kW systems about $25,000 to $35,000.
What is the average solar installation cost per watt in Los Angeles?
Published 2026 averages range from about $2.50 to $3.14 per watt, depending on the source and equipment. Tile or flat roofs, panel upgrades, and battery storage push a quote toward the higher end.
Is solar cheaper on LADWP or SCE?
The installed price is about the same. What differs is what the system is worth. LADWP credits exported solar close to your rate schedule’s energy price, so panels alone still pay off. SCE customers are on NEM 3.0, where exports earn much less, so a battery matters more.
Is there still a federal tax credit for solar in Los Angeles?
Not for cash or loan purchases. The 30 percent residential credit ended for systems placed in service after December 31, 2025. Lease, PPA, and prepaid providers may still pass along the value of a commercial credit through lower pricing, so compare those terms carefully.
Should I get a solar quote with a battery in Los Angeles?
For SCE customers under NEM 3.0, yes. Ask for quotes with and without a battery so you can compare. LADWP customers have more flexibility, but a battery can still help with evening rates and backup power.
How long does it take solar to pay for itself in Los Angeles?
Published 2026 models suggest roughly 7 to 9 years on LADWP and 10 to 13 years on SCE for panels only. Adding a battery on SCE can improve the result. Your usage, system size, and rate plan set your actual payback.
Does my roof condition affect my solar estimate?
Yes. A roof that needs repair or replacement before installation adds to the total project cost, and tile or flat roofs cost more to work on. A quality installer checks this early and lists it in the estimate.
How accurate is a solar cost estimate before installation?
A well-built estimate using your address and utility data is a strong starting point. The final price can shift after the on-site assessment, mainly because of roof condition, electrical panel capacity, and shading that satellite imagery may miss.
