Solar Incentives & Rebates in California 2026

If you’ve been researching solar in California and just found out the 30% federal tax credit expired on December 31, 2025, you’re not alone, and you’re right to feel confused. Most of what you’ll read online still talks about the federal credit as if it exists. It doesn’t. Not for new residential installations completed after that date.

But here’s what those same articles won’t tell you clearly: California still has some of the strongest solar incentives in the country — and the combination of rising electricity rates, strong year-round sun, and remaining state programs means solar still makes serious financial sense for most California homeowners in 2026.

The math changed. The opportunity didn’t disappear.

This guide covers every program still available to California homeowners in 2026, what each one is actually worth, who qualifies, and how to stack them correctly.

California Solar Incentives 2026 — Quick Snapshot

WHAT EXPIRED — AND WHAT IT MEANS

The federal Residential Clean Energy Credit, the 30% Investment Tax Credit (ITC), applied to any solar system installed and operational before December 31, 2025. For a typical California system costing around $22,000 to $28,000, that credit was worth $6,600 to $8,400 directly off your federal tax bill.

For systems installed after December 31, 2025, the residential credit is zero.

This is a real change and worth acknowledging honestly. It lengthens payback periods for most California homeowners. But California’s electricity rates — among the highest in the nation — and its remaining incentive stack mean the long-term financial case for solar remains strong.

How Much Do Solar Panels Cost in California in 2026?

The average solar installation in California costs $2.44 per watt before incentives, according to EnergySage February 2026 marketplace data — down from $2.80/W in 2023. California has seen significant price compression as installer competition increased and panel costs fell globally.

For a typical 9 kW system that works out to approximately $21,960 gross before any incentives. After SGIP and property tax exclusion, most California homeowners are looking at a net cost of $13,000 to $18,000 depending on system size, utility territory, and SGIP eligibility.

Cost by System Size — California 2026

*Net cost estimates include SGIP standard rebate ($150/kWh, 10kWh battery) and property tax exclusion value. Does not include equity or DAC-SASH programs.

What affects your final cost most in California is not the panel brand — it’s your utility territory, your roof complexity, and whether you add battery storage. San Diego homeowners typically see the strongest ROI despite higher installation costs because SDG&E rates are the highest in the country.

PG&E vs SCE vs SDG&E — Does Your Utility Affect Your Savings?

Yes — significantly. Your utility determines your electricity rate, your TOU schedule, your NEM 3.0 export credits, your SGIP program administrator, and even your interconnection wait time. Two California homeowners with identical solar systems can have very different financial outcomes based on nothing more than which utility serves their address.

California Utility Solar Comparison

Key differences that affect your solar economics:

• PG&E: Highest residential rates in the state but also notorious for the slowest interconnection process — often 8 to 12 weeks for Permission to Operate. Budget extra time. Their TOU-C rate plan is generally optimal for solar-plus-battery customers.

• SCE: Strong solar economics in most of Southern California. Their TOU-D-PRIME rate plan is specifically designed for solar and battery customers and typically produces the best bill outcomes.

• SDG&E: The highest residential electricity rates in the continental United States — sometimes exceeding $0.55/kWh at peak. This makes solar economics exceptional in San Diego. Payback periods here can be 2 to 3 years shorter than the same system in PG&E territory.

• LADWP: Los Angeles Department of Water and Power is a municipal utility not subject to CPUC rules. It operates its own net metering program that is more similar to the old NEM 2.0 structure — meaning solar export credits are more valuable than under NEM 3.0. This is a significant advantage for LADWP customers.

• SMUD: Sacramento Municipal Utility District has lower rates than PG&E, SCE, or SDG&E — which means lower electricity savings per kWh offset, and therefore longer payback periods. Solar is still worthwhile in Sacramento but the economics are less dramatic than San Diego or San Francisco.

PROPERTY TAX EXCLUSION PROTECT YOUR HOME’S VALUE

California offers an Active Solar Energy System Exclusion that prevents your solar installation from increasing your property tax assessment. In plain terms: solar will increase your home’s market value, studies consistently show increases of $15,000 to $25,000 for a quality residential system, but it will not increase what you pay in property taxes.

This exclusion is currently active for systems completed before January 1, 2027. At California’s average effective property tax rate of around 0.75%, a $20,000 increase in assessed value would cost you roughly $150 per year in additional taxes. Over 25 years that’s $3,750 saved, completely invisibly, just by going solar before the exclusion deadline.

This is not a rebate you apply for. It is automatically applied to qualifying solar installations. Make sure your installer is aware of the exclusion so it is properly documented with your county assessor.

SGIP — THE BATTERY REBATE THAT CHANGES THE CALIFORNIA CALCULATION

The Self-Generation Incentive Program (SGIP) is California’s flagship battery storage incentive, administered by the California Public Utilities Commission (CPUC). It is available to customers of PG&E, Southern California Edison (SCE), San Diego Gas & Electric (SDG&E), and SoCalGas.

In 2026, SGIP is the most important incentive for California homeowners to understand — more important than almost anything else on this list. Here’s why: under NEM 3.0, solar-only systems generate significantly less value from grid exports than they used to. The combination of solar plus battery storage is now essentially required to maximize the financial return of going solar in California. And SGIP is what makes battery storage affordable.

SGIP Rebate Tiers

• Standard SGIP Rebate: $150 per kWh For a standard 10 kWh home battery, that’s a $1,500 rebate. For a 13.5 kWh Tesla Powerwall, approximately $2,025.

• Equity Rebate: Higher amounts for qualifying households Low-income customers and those living in disadvantaged communities (DAC) receive significantly higher rebates — up to $850 per kWh depending on eligibility tier.

• Equity Resiliency Rebate: Up to $1,100 per kWh The highest tier is reserved for low-income households in high fire-risk areas or households with medical baseline needs. At $1.10 per Wh, a 10 kWh battery could receive up to $11,000 — covering a significant portion or even the entire cost of battery storage.

Solar + Battery Storage in California — Why It’s Now Essential

Under NEM 2.0, solar-only systems made complete financial sense in California. You generated electricity during the day, exported the excess to the grid at full retail rate, and drew that credit back at night. It was simple, and it worked.

Under NEM 3.0, that model is broken. Export credits are now 75% lower than retail rate. Excess solar electricity sent to the grid earns almost nothing. The way to maximise the value of your solar system in California in 2026 is to use as much of what you generate as possible — and battery storage is what makes that possible.

How solar + battery works under NEM 3.0:

• Your panels generate electricity during peak sun hours (typically 10am – 3pm)
• Excess electricity charges your battery instead of exporting to the grid at low credit rates
• In the evening when grid rates peak (4pm – 9pm), you discharge your battery instead of buying expensive peak electricity
• You only export to the grid what you can’t store — and earn modest credits for that

Battery sizing guide for California:

• 10 kWh battery (1 Powerwall) — covers most evening usage for average household, qualifies for $1,500 standard SGIP rebate
• 20 kWh battery (2 Powerwalls) — full overnight coverage, full backup during outages, $3,000 standard SGIP rebate
• 30 kWh+ — EV charging overnight, whole-home backup, maximises SGIP rebate

NEM 3.0 NET BILLING WHAT CHANGED AND WHAT IT MEANS

This is the change that reshaped California solar economics more than any other and most homeowners don’t fully understand it.

California’s legacy net metering (NEM 2.0) gave solar customers full retail rate credits for every kilowatt-hour they exported to the grid. If your utility charged $0.30/kWh, you received $0.30/kWh in credit for what you sent back.

Since April 15, 2023, all new grid-tied solar systems in PG&E, SCE, and SDG&E territories are under the Net Billing Tariff (NEM 3.0). Under this system, export credits are calculated at the “avoided cost” rate — essentially the wholesale rate the utility pays for electricity — which is roughly 75% lower than the retail rate you pay.

What this means in plain numbers: Under NEM 2.0, exporting 1 kWh at a $0.30 retail rate earned you $0.30 in credit. Under NEM 3.0, that same 1 kWh might earn you $0.05 to $0.08 in credit.

This fundamentally changes how you should size and use your system:

• Solar-only systems are still financially viable but need to be sized to closely match your actual usage — overproducing to bank credits no longer makes financial sense.
• Solar plus battery is the new optimal configuration. You self-consume more of what you generate, charge your battery during peak production hours, and discharge it during evening peak rate hours — maximizing the value of every kilowatt your panels produce.
• Time-of-Use (TOU) rate plans become critically important under NEM 3.0. Your installer should be optimizing your system design specifically around your utility’s TOU schedule.

NEM 2.0 grandfathering: Systems installed before April 15, 2023 remain on NEM 2.0 terms for 20 years from their interconnection date. If you have an existing system under NEM 2.0, this is a significant asset — do not do anything that would reset your interconnection date.

Community Solar in California — For Renters and Those Who Can’t Install

Rooftop solar is not an option for everyone. If you rent, live in an HOA that restricts panels, have a shaded or structurally unsuitable roof, or simply prefer not to install panels on your home — community solar offers an alternative path to lower electricity bills.

Community solar works by allowing you to subscribe to a share of a large off-site solar installation. The electricity generated by your share is credited to your utility bill, reducing what you pay — even though the panels are not on your roof.

Current state of community solar in California:

California’s community solar history has been complicated. The CPUC has repeatedly delayed and restructured community solar programs, often ruling in favour of utility proposals that limited export credit values — which in turn limited the financial benefit of community solar subscriptions.

The most recent development: the CPUC pushed final implementation of a new community solar program to January 1, 2026, pending federal Solar For All grant funding. As of early 2026, programme details are still being finalised. The financial benefit of any community solar subscription in California depends heavily on which credits apply under the final programme rules.

Who benefits most from community solar in California:

• Renters who cannot install rooftop solar
• Condo or apartment owners with HOA restrictions
• Homeowners with heavily shaded roofs or north-facing roof orientation
• Multi-family property residents
• Low-income households — the RSSE programme accepts community solar arrangements

California Solar Lease vs Buy in 2026 — Which Is Better?

This is one of the most common questions California homeowners ask — and the answer matters more in 2026 than it ever has, because of how incentives like SGIP and DAC-SASH work.

The core issue: who claims the incentives?

Most California solar incentive programmes require the system owner to claim the benefit. If you lease your solar system — meaning a third-party company owns the panels on your roof — that company claims any available incentives, not you. They pass some savings to you through lower lease payments, but you do not receive the full value.

California Solar Financing Comparison

The 2026 verdict for most California homeowners:

• If you can afford it — cash purchase maximises lifetime savings and gives you access to all incentive programmes
• If you need financing — a solar loan is almost always better than a lease or PPA in California. You still own the system and access all incentives
• If you qualify for DAC-SASH or RSSE — these programmes are specifically designed for those who may struggle with upfront costs. Investigate these before considering a lease
• Leases and PPAs — not recommended for most California homeowners in 2026. The combination of NEM 3.0 and lost SGIP access means leases are significantly less financially attractive than they were under NEM 2.0

DAC-SASH — FOR LOW-INCOME HOMEOWNERS IN DISADVANTAGED COMMUNITIES

The Disadvantaged Communities — Single-family Affordable Solar Homes (DAC-SASH) program is one of the most valuable solar incentives in California for qualifying homeowners, administered by GRID Alternatives.

It offers a flat incentive of $3 per watt for solar installations between 1 and 5 kilowatts. On a 5 kW system, that is a $15,000 incentive — enough to cover a substantial portion of installation costs.

To qualify you must:

• Own a single-family home
• Live in a designated California Disadvantaged Community
• Meet income requirements (under 80% of Area Median Income)
• Be a customer of PG&E, SCE, or SDG&E

This program has limited annual funding of $8.5 million and runs through 2030. Slots fill quickly. If you think you might qualify, this should be the first program you investigate — before getting any installer quotes.

RSSE — RESIDENTIAL SOLAR AND STORAGE EQUITY PROGRAM

The Residential Solar and Storage Equity (RSSE) program is the newest and most generously funded low-income solar program in California. The California Public Utilities Commission authorized $280 million in new funding for this program, making it the most significant equity solar initiative the state has launched.

RSSE is part of the SGIP framework and focuses on income-qualified households installing battery storage — with or without solar panels. For qualifying households, the rebates can cover up to 100% of the cost to install solar and battery storage.

Key facts about RSSE:

• Available to California residential customers meeting income requirements or living in disadvantaged communities
• Customers must qualify under CARE, FERA, or approved community-based criteria
• Customer ownership is not required — leases and PPAs also qualify, unlike most other incentive programs
• Focuses primarily on battery storage, making it the most powerful remaining incentive for low-income households in 2026

If your household income is at or below 80% of the Area Median Income for your area, RSSE combined with DAC-SASH can potentially make solar and battery storage available to you at little to no out-of-pocket cost.

Local Utility Rebates

California’s three major IOUs (PG&E, SCE, SDG&E) do not currently offer direct solar rebates beyond SGIP. However, several municipal utilities offer their own programmes:

• Alameda Municipal Power: $500 rebate for homeowners with incomes below $106,000, homes built before 2020
• LADWP: Check current offerings at ladwp.com — programmes change seasonally
• SMUD: Solar rebates available periodically — check smud.org for current status
• Other Community Choice Aggregators (CCAs) may have local programmes not widely publicised

PACE FINANCING — NOT A REBATE BUT WORTH UNDERSTANDING

California is one of only three states that offers Property Assessed Clean Energy (PACE) financing for residential solar. This is not a rebate or incentive, it is a financing mechanism, but it is worth understanding because it allows homeowners to install solar with no money upfront.

PACE ties your solar loan to your property rather than to you personally. Repayment is made through your property tax bill over a period of 10 to 20 years. If you sell your home before the loan is paid off, the obligation transfers to the new owner.

The advantage is accessibility — PACE qualification is based on property equity rather than personal credit scores, making it available to homeowners who may not qualify for traditional solar loans. The disadvantage is that interest rates are typically higher than standard solar loans and the mandatory disclosure requirements exist for good reason — read every term carefully before signing.

IS SOLAR STILL WORTH IT IN CALIFORNIA IN 2026?

For most California homeowners — yes, and here is the honest breakdown.

California has the highest residential electricity rates in the continental United States, averaging over $0.30 per kWh for most utility customers and significantly higher during peak hours under TOU pricing. PG&E, SCE, and SDG&E have all raised rates substantially in recent years with no sign of slowing down.

The average California solar installation in 2026 costs approximately $2.44 per watt before incentives, according to EnergySage February 2026 marketplace data. For a typical 9 kW system that works out to approximately $21,960 gross.

California’s electricity rates are high enough that even at a 9 to 10 year payback, solar panels on a 25-year warranty asset still deliver 15+ years of effectively free electricity. Add the property tax exclusion’s value and the rising-rate environment, and the financial case remains solid for most homeowners.

The difference in 2026 is that battery storage matters more than it ever did — and SGIP makes battery storage financially accessible for most households.

HOW TO STACK CALIFORNIA INCENTIVES IN 2026

For standard homeowners: Property Tax Exclusion + SGIP Battery Rebate + NEM 3.0 optimized system sizing = best available combination

For low-income homeowners in disadvantaged communities: DAC-SASH ($3/W up to 5kW) + SGIP Equity Resiliency (up to $1.10/Wh) + RSSE program = potentially $0 out-of-pocket

For all homeowners: Check your specific municipal utility for any local rebates before signing any contract. These change frequently and are often underpublicized.

How Long Does Going Solar Take in California?

California is one of the slowest states in the US for solar installation — not because of the actual installation, which takes one to two days, but because of the permitting and utility interconnection process. Setting realistic timeline expectations is essential, especially if you are planning around SGIP waitlists or the property tax exclusion deadline.

California Solar Installation Timeline

The PG&E interconnection problem: PG&E’s interconnection queue is notoriously slow. In 2024 and 2025, some customers waited 12 to 16 weeks for Permission to Operate after their system was physically installed. Your system cannot legally generate electricity until PTO is granted. Factor this into your timeline planning — particularly if you are trying to capture current SGIP pricing before programme budgets are exhausted.

San Diego (SDG&E) and SCE territories typically process interconnection in 4 to 6 weeks. LADWP processes in 3 to 5 weeks for most standard residential systems.

California Solar by City — Does Location Matter?

Yes — and more than most people realise. Your city determines your peak sun hours, your utility company, your local permit requirements and fees, and sometimes access to city-specific incentive programmes. Here’s how the major California metro areas compare for residential solar economics.

California Solar by City

City-specific notes:

San Diego: The strongest residential solar market in California. SDG&E’s rates are among the highest in the nation, excellent year-round sun, and short interconnection wait times. A 9 kW system in San Diego often pays back 2 to 3 years faster than the same system in San Francisco.

San Francisco / Bay Area: Lower peak sun hours than Southern California, but PG&E’s extremely high rates offset this almost entirely. The economics are strong — but factor in PG&E’s slow interconnection process and higher permit fees in some Bay Area jurisdictions.

Los Angeles: Homeowners in LADWP territory have a significant advantage — LADWP’s net metering policy is closer to the old NEM 2.0 structure than NEM 3.0, making solar-only systems more financially attractive than in PG&E or SCE territory. If you’re in LADWP territory, confirm your net metering terms carefully before adding a battery solely for export optimisation.

Sacramento: SMUD’s lower rates mean lower savings per kWh offset — payback periods are typically 2 to 3 years longer than San Diego or the Bay Area. Solar is still worthwhile, but don’t expect the same dramatic numbers you might see quoted for other California cities.

How to Avoid Solar Scams in California

California’s solar market is large, competitive, and unfortunately home to a significant number of bad actors. The combination of high home values, high electricity rates, and complex incentive programmes makes California homeowners a prime target for misleading sales tactics, exaggerated savings claims, and outright fraudulent contracts.

Check the installer’s CSLB licence:

Every solar installer in California must hold a valid licence from the California Contractors State License Board (CSLB). The relevant licence class is C-10 (Electrical) or B (General Building). Verify at cslb.ca.gov before signing anything. An unlicensed installer cannot legally pull permits — meaning your system may not pass inspection, and you cannot access utility interconnection or any incentive programmes.

Red flags to watch for:

• Door-to-door salesperson who pressures you to sign ‘today only’ — walk away
• Quote that prominently features the 30% federal tax credit (it expired December 31, 2025)
• Installer who cannot confirm they can submit SGIP reservations on your behalf
• Lease or PPA presented as if it’s equivalent to ownership — it isn’t
• Savings projections that assume your electricity rate stays flat — California rates rise ~6-8% annually
• No physical office address or only a PO box
• Cannot provide references from customers in your specific utility territory

How to verify SGIP certification:

SGIP requires installers to be authorised by the programme administrator for your utility. Ask any installer directly: ‘Are you an authorised SGIP programme administrator for my utility?’ Then verify on the CPUC’s SGIP website at selfgenca.com. An installer who cannot confirm this cannot submit your SGIP reservation.

The 3-quote rule:

California solar pricing can vary by $5,000 to $12,000 between installers for the exact same system. There is no single standard price. Always get at least three written quotes, compare them line by line, and ask each installer to explain any significant price difference. The lowest quote is not always the best deal — but the highest is rarely justified.

California Solar in 2027 and Beyond — What’s Coming

California’s solar landscape will continue to evolve. Here’s what homeowners considering solar in 2026 need to know about what’s coming — both the risks and the opportunities.

Property Tax Exclusion Expiry — January 1, 2027

California’s Active Solar Energy System Exclusion, which prevents solar installations from increasing your property tax assessment, expires for systems completed after January 1, 2027. The California legislature has not yet passed an extension. If you’re planning to go solar in late 2026, make sure your system is fully installed and has received Permission to Operate before this date to lock in the exclusion. This represents a real deadline — not a sales tactic.

SGIP Funding — Running Low

The SGIP general market budget is largely depleted as of early 2026. Equity and Equity Resiliency budgets are better funded but also seeing increasing demand. If you qualify for any SGIP tier, apply sooner rather than later — programme administrators prioritise reservations in the order they are received.

Community Solar Programme Launch

California’s CPUC is expected to finalise and launch a new community solar programme in 2026, with implementation potentially extending into 2027. If passed with meaningful export credit values, this could significantly improve the economics of community solar for renters and those who cannot install rooftop panels.

Electricity Rate Trajectory

PG&E, SCE, and SDG&E have all received CPUC approval for significant rate increases through 2027 and beyond. California’s electricity rates are projected to continue rising at 5 to 8% per year. Every year you delay solar is another year of paying those increasing rates without the offset. The financial case for solar in California does not weaken over time — it strengthens.

NEM 3.0 — Will It Change?

There is ongoing advocacy from solar industry groups to modify NEM 3.0’s export credit structure. However, no CPUC proceeding to revise NEM 3.0 is expected to conclude before 2027. Systems installed in 2026 should be planned and sized for NEM 3.0 economics; any future policy improvement would be a bonus, not a baseline assumption.

WHY INSTALLER CHOICE MATTERS IN CALIFORNIA

Several California incentive programs — particularly SGIP and DAC-SASH — require your installer to submit applications and reservations on your behalf before installation begins. If you hire an installer who is unfamiliar with these programs, you will simply miss out on the rebates with no way to recover them after the fact.

Before signing any contract ask your installer directly:

• Are you certified to submit SGIP reservations?
• Can you check my eligibility for DAC-SASH and RSSE before we proceed?
• How will you size my system specifically for NEM 3.0 economics and my TOU rate plan?
• What is your experience with battery storage installation and SGIP paperwork?

Any experienced California solar installer should answer all four questions confidently and in writing.

FAQ

Is the federal solar tax credit available in California in 2026?

No. The residential 30% Investment Tax Credit expired for new installations completed after December 31, 2025. Systems installed before that date can still claim the credit on a 2025 tax return.

Does California have a state solar tax credit?

No. California does not offer a state-level solar tax credit. The state’s incentives are structured as property tax exclusions, battery rebates through SGIP, and equity programs for low-income households.

What is the best solar incentive in California for 2026?

For most homeowners it is the SGIP battery rebate combined with the property tax exclusion. For income-qualified homeowners, DAC-SASH at $3 per watt is the single most valuable program in the state.

Will solar increase my property taxes in California?

No. California’s Active Solar Energy System Exclusion prevents solar installations from increasing your property tax assessment. This exclusion currently applies to systems completed before January 1, 2027.

Is NEM 3.0 bad for solar in California?

It reduced the value of grid exports by approximately 75% compared to NEM 2.0. It makes solar-only systems less optimal than before and makes solar-plus-battery the better configuration for most households. It did not eliminate the financial case for solar — it changed the optimal system design.

Can renters benefit from solar incentives in California?

Renters cannot install rooftop solar but may access community solar programs. The RSSE program also accepts leases and PPAs, meaning renters who can arrange third-party-owned systems on their property may qualify.
