Yes, California home solar still pays in 2026. The state has some of the nation’s highest power prices, about 35 cents per kWh (EIA, April 2026), so offsetting your own use saves the most. New systems run on NEM 3.0 net billing, which rewards pairing solar with a home battery. The 30% federal 25D homeowner credit ended December 31, 2025.
According to MySolarFY’s analysis (July 2026), a typical 7 kW California rooftop produces about 11,200 kWh a year (NREL PVWatts v8, Sacramento), which at California’s average residential rate of 35.25 cents per kWh (EIA, April 2026) equals roughly $3,900 of grid power a year, though under NEM 3.0 net billing what you actually keep depends on how much you use on-site versus export. Model your own address before you decide.
California home solar still pays in 2026, but the math changed in a way a lot of older guides have not caught up with. California homes pay some of the highest electricity prices in the country, which is the reason solar pays off here. What shifted is how the utility pays you for the power you send back: new systems are on NEM 3.0, the Net Billing Tariff, which credits exports far below the old near-retail rate and makes a home battery much more valuable than it used to be. This guide covers what California home solar costs in 2026, how NEM 3.0 actually works, the incentives that still apply (and the federal one that ended), and how to start, so you can check your address in about a minute.
Updated July 2026 for California’s NEM 3.0 net billing rules and the current 2026 incentive landscape.
What California homeowners need to know in 2026
- California power is expensive, which is what makes solar pay. The U.S. residential average is about 18.83 cents per kWh (EIA, as of March 2026), and California’s investor-owned utility rates are among the highest in the nation, well above that average.
- New solar is on NEM 3.0, the Net Billing Tariff. Since April 15, 2023, new PG&E, SCE, and SDG&E systems earn export credits at hourly avoided-cost values that are well below the retail rate (CPUC, as of 2026).
- A home battery now does the heavy lifting. Because midday exports are worth little, storing your solar to use during the 4 to 9 pm peak is where the savings are (EIA Today in Energy, as of 2026).
- California excludes solar from your property taxes, but has no state solar tax credit. A qualifying system is not added to your assessed value, an exclusion currently scheduled to sunset January 1, 2027 (CA BOE, as of 2026).
- SGIP still helps pay for a battery, mostly for equity customers. California’s Self-Generation Incentive Program offers storage rebates in 2026, with the largest reserved for income-qualified and high fire-risk households (CPUC SGIP, as of 2026).
- The 30% federal homeowner credit (Section 25D) ended after December 31, 2025 (IRS, as of January 1, 2026), so a California homeowner who buys solar in 2026 cannot claim it.
Why residential solar still pays in California
The reason solar pays in California is the price of the power it replaces. The U.S. residential electricity average is about 18.83 cents per kWh (EIA, as of March 2026), and California’s big utilities, PG&E, SCE, and SDG&E, charge well above that, with residential rates that commonly run about 35 to 45 cents per kWh in 2026, among the highest in the country (CPUC, as of July 2026). So every kilowatt-hour your roof makes is an expensive one you do not have to buy back. New residential solar customers also move onto an electrification time-of-use rate, where power is most expensive during the 4 to 9 pm peak (CPUC, as of 2026). That evening peak is exactly when your panels are winding down, which is the heart of why the new rules reward a battery. To see how the bill side works, read how solar lowers your electricity bill.
Your own production is what turns that high rate into savings. California gets an excellent solar resource, and a well-placed roof offsets a large share of a typical home’s use. Because output depends on your roof’s pitch, shading, and orientation, estimate your specific roof with NREL’s free PVWatts calculator rather than a generic number, then weigh the numbers with our guide on whether solar panels are worth it.

How does NEM 3.0 net billing work in California?
NEM 3.0 credits the power you export at hourly avoided-cost values, not at the retail rate. California’s regulator, the CPUC, replaced the old NEM 2.0 program with the Net Billing Tariff, widely called NEM 3.0, for interconnection applications submitted on or after April 15, 2023 in PG&E, SCE, and SDG&E territory (CPUC, as of 2026). Under NEM 2.0, exports earned credits close to the full retail rate. Under NEM 3.0, each exported kilowatt-hour is credited at a time-varying avoided-cost value that is generally well below retail, and those values are lowest at midday when the grid is flush with solar and highest on late-summer evenings (EIA Today in Energy, as of 2026). For the general mechanics, see how net metering and net billing credit your solar exports.
If you already had solar, you are likely grandfathered. Customers who submitted a complete interconnection application before April 15, 2023 stay on NEM 2.0 terms for 20 years from their interconnection date (CPUC, as of 2026). The table below compares the two at a high level. The practical takeaway for a new 2026 system is simple: exporting surplus solar to the grid is no longer where the value is, so the system should be sized and paired with storage to use your own power, not to sell it cheap.
| Feature | NEM 2.0 (legacy) | NEM 3.0 / Net Billing (new since April 15, 2023) |
|---|---|---|
| Export credit basis | Near the full retail rate | Hourly avoided-cost value, generally well below retail |
| When exports are worth most | Roughly the same all day | Late-summer evenings; very low at midday |
| Best system design | Size to offset annual use | Size for self-use, usually paired with a battery |
| Who is on it | Applied before April 15, 2023 (20-year grandfather) | Applied on or after April 15, 2023 |
Why a home battery now matters in California
Under NEM 3.0, a battery is what protects your savings. Because midday exports earn so little and evening power on a time-of-use rate is so expensive, the winning move is to store your solar and use it during the 4 to 9 pm peak instead of buying grid power then (CPUC, as of 2026). That is a real change from the NEM 2.0 era, when a solar-only system made strong economic sense on its own. A battery also gives you backup during a Public Safety Power Shutoff, which matters in much of California.
Note: California’s Self-Generation Incentive Program (SGIP) still offers rebates toward a home battery in 2026, but the largest incentives are reserved for equity and equity-resiliency customers, such as income-qualified households or those in high fire-threat districts (CPUC SGIP, as of 2026). General-market residential funding is smaller and can be waitlisted, so check the live SGIP program metrics for current availability in your utility before you count on a specific rebate (SGIP Statewide, as of June 2026).
How does solar payback compare with and without a battery under NEM 3.0?
Under NEM 3.0, a battery does not just add cost, it changes where your solar’s value comes from. Without storage, much of your midday production is exported and credited at low avoided-cost values. With storage, you keep that power and use it during the expensive 4 to 9 pm peak, so more of every kilowatt-hour offsets a high retail rate instead of a low export rate (CPUC, as of 2026). The illustrative comparison below is modeled on a representative California home whose annual production we pulled from NREL’s live PVWatts. For what a battery itself runs, see our guide to home solar battery costs.
Modeled inputs (shown so you can check them): a 7 kW rooftop system at a representative Sacramento ZIP (95823), which NREL’s PVWatts v8 estimates produces about 11,200 kWh per year (NREL PVWatts v8, run July 2026). For contrast, the same system at a coastal San Diego ZIP (92109) models about 11,050 kWh per year, so annual production is broadly similar across California and the bigger variable is your utility’s rate and NEM 3.0 net-billing terms. Your own roof will differ with pitch, shading, and orientation, so model your exact address before you decide.
| Representative 2026 scenario | All-in cost before incentives | How your solar’s value is captured under NEM 3.0 | Illustrative simple payback |
|---|---|---|---|
| Solar only (about 7 kW, ~11,200 kWh/yr) | Roughly $22,000 to $24,000 | Self-used daytime power offsets the retail rate, but surplus is exported at low avoided-cost values, so evening power is still bought from the grid | About 10 to 14 years |
| Solar plus battery (about 7 kW, ~11,200 kWh/yr, with about 13.5 kWh storage) | Roughly $35,000 to $37,000 | Stored solar covers the 4 to 9 pm peak, so more of each kilowatt-hour offsets the high retail rate instead of a cheap export, and you gain backup power | About 9 to 13 years, plus outage protection |
Illustrative estimate only, not a quote or a guarantee. It uses a representative 7 kW system modeled in NREL’s PVWatts v8 at a Sacramento ZIP (95823), which returns about 11,200 kWh per year (estimate your own roof with NREL’s free PVWatts calculator), California investor-owned utility residential rates in the high-30s to mid-40s cents per kWh (CPUC, as of 2026), representative 2026 California costs of about $3.00 to $3.50 per watt for solar and about $10,000 to $15,000 for storage, a cash purchase, and no federal tax credit, since the 30% residential credit (Section 25D) ended after December 31, 2025 (IRS, as of January 1, 2026). Worked roughly: a solar-only system self-uses perhaps a third of its output at about 42 cents per kWh and exports the rest at low avoided-cost values, saving on the order of $2,000 to $2,500 a year, so about $23,000 divided by that is roughly 10 to 14 years. Adding storage lifts self-use toward 80 percent or more, saving on the order of $3,000 to $3,800 a year, so about $36,000 divided by that is roughly 9 to 13 years, before counting backup value. Your actual cost, production, rate, savings, and payback depend on your utility, roof, usage, and financing, and they are not guaranteed. Get a written quote before you decide.
What residential solar costs in California in 2026
A home solar system in California is a five-figure investment, and how you pay decides what you keep. Pricing depends on system size, equipment, your roof, and whether you add a battery, which is common under NEM 3.0, so the most reliable number is a written quote rather than an average. For local pricing and a breakdown of where the money goes, see our breakdown of solar costs and potential savings and how much solar panels cost. Payback in California is longer than it was under NEM 2.0 for a solar-only system, while pairing solar with storage tends to shorten it by offsetting expensive peak power, so model both before you decide.
| Path | Up-front cost | Who keeps the incentives | Best when |
|---|---|---|---|
| Cash purchase | Full system cost | You, the owner | You want the fastest payback and the most lifetime savings |
| Solar loan | Little to none, financed | You, the owner | You want ownership without paying cash up front |
| Lease or PPA | $0-up-front where eligible | The third-party owner | You prefer no up-front cost and a simpler, fixed monthly bill |
A lease or PPA can mean no up-front cost for eligible homeowners, but it is a long-term agreement with monthly payments, not free solar, and the company that owns the panels keeps any owner-level incentive.
The incentives that still apply in California (and the federal one that ended)
California’s real homeowner benefits in 2026 are net billing, the property-tax exclusion, and SGIP for storage. The table sorts what applies from what does not, so you can plan on facts.
| Program | Applies in California? | What it does |
|---|---|---|
| NEM 3.0 net billing | Yes (reduced) | Credits exports at hourly avoided-cost values, well below retail (CPUC) |
| Property-tax exclusion | Yes (sunset Jan 1, 2027) | A qualifying solar system is not added to your assessed value (CA BOE) |
| SGIP battery rebate | Yes (equity-focused) | Storage rebates, largest for income-qualified and fire-risk customers (CPUC SGIP) |
| State solar income-tax credit | No | California has no statewide residential solar income-tax credit (DSIRE) |
| Federal residential credit (Section 25D) | No, it ended | The 30% homeowner credit ended for systems placed in service after Dec 31, 2025 (IRS) |
For the full statewide rebate picture, see our guide to California solar rebates and the incentives available.
What the end of the federal tax credit means in California
The federal homeowner credit is gone, but California’s programs are not. The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act, so a California homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS Residential Clean Energy Credit, as of January 1, 2026). You will still find guides and installer pages quoting the old 30% figure; the accurate answer for 2026 is that the homeowner version already ended. Net billing, the property-tax exclusion, and SGIP were not affected. For the full timeline, see what the federal solar tax credit change means in 2026.
One federal exception exists, and it is not the homeowner’s to claim. A separate commercial credit, Section 48E, is claimed by the business that owns a leased or PPA system, not by the resident (IRS Clean Electricity Investment Credit, as of 2026). So on a lease or PPA you do not file for a federal credit yourself; the system owner does. The 25D homeowner credit, by contrast, ended after December 31, 2025.
Is your California home a good fit for solar?
Most California homes are good candidates, with a few things to check. A south, west, or southwest-facing roof with minimal shading produces the most, and west-facing arrays pair especially well with NEM 3.0 because they push production toward the valuable late-afternoon hours. Your roof’s age and condition matter too, since it is best to replace an aging roof before panels go on. If you are building or doing major work, note that California’s building code requires solar on many new homes, so a new build may already be solar-ready. An installer will confirm your roof, panel layout, and whether a service-panel upgrade is needed for solar plus a battery. Before the system can switch on, your project also needs a local building permit and utility interconnection approval; if you are in the Los Angeles basin, San Diego, or the Inland Empire, our guide to solar permitting in Southern California lays out the local plan-check queues and Permission to Operate steps.
How to choose a solar installer in California
California has a deep, competitive market of installers, which is good for you because it means real competition on price and service. Rather than chasing a “best installer” list, screen any company against objective criteria:
- A valid California Contractors State License Board (CSLB) license, typically a C-46 solar or C-10 electrical classification.
- NABCEP certification, the industry’s professional standard for PV installers.
- A clear workmanship and equipment warranty in writing.
- Real experience designing for NEM 3.0 and batteries, since a NEM 3.0 system is sized and paired with storage differently than an old NEM 2.0 system.
- A written production estimate and a transparent quote that does not count the federal credit that ended after December 31, 2025. For a checklist, see the right questions to ask a solar installer.
MySolarFY matches you with licensed installers that serve your area so you can compare real local quotes side by side, with no obligation. To see how California stacks up against other markets, browse our solar by state guides.

Frequently asked questions
Is residential solar energy worth it in California in 2026?
For most owner-occupied California homes with decent sun, yes, though the case now leans on self-use rather than selling power back. California’s investor-owned utilities charge among the highest rates in the country, well above the U.S. residential average of about 18.83 cents per kWh (EIA, as of March 2026), so every kilowatt-hour you make and use is a costly one you avoid. Under NEM 3.0 the savings come from using your own solar, often with a battery, instead of exporting it cheap. Savings are not guaranteed and depend on your roof, usage, rate, and whether you add storage, but the high local rates keep California a strong solar market.
How is NEM 3.0 different from the old net metering?
NEM 3.0, the Net Billing Tariff, credits the power you export at hourly avoided-cost values that are well below the retail rate, while the older NEM 2.0 credited exports close to full retail (CPUC, as of 2026). It applies to interconnection applications submitted on or after April 15, 2023 in PG&E, SCE, and SDG&E territory; earlier systems are grandfathered on NEM 2.0 for 20 years. The practical effect is that exporting surplus solar is worth much less than it used to be, so new systems are designed for self-use and usually paired with a battery to shift solar into the expensive evening hours.
Do I need a battery with solar in California now?
Not strictly, but under NEM 3.0 a battery is usually what makes the numbers work. Because midday exports earn little and evening power is expensive on a time-of-use rate, storing your solar to use during the 4 to 9 pm peak captures far more value than selling it to the grid (CPUC, as of 2026). A battery also provides backup during a Public Safety Power Shutoff. California’s SGIP can help pay for storage, with the largest rebates reserved for income-qualified and high fire-risk customers, so check the live SGIP program metrics for current availability before counting on a rebate.
Will California pay homeowners to install solar panels?
Not with a direct cash payment for the panels themselves. California has no statewide solar income-tax credit or rebate for buying panels (DSIRE, as of 2026). What the state does offer in 2026 is the SGIP rebate toward a home battery, with the largest amounts reserved for income-qualified and high fire-risk customers (CPUC SGIP, as of 2026), the property-tax exclusion that keeps solar off your assessed value through its January 1, 2027 sunset (CA BOE, as of 2026), and NEM 3.0 bill credits for the power you export. The 30% federal homeowner credit (Section 25D) is not one of them; it ended after December 31, 2025 (IRS, as of January 1, 2026).
Is solar mandatory in California?
For most new homes, yes; for existing homes, no. Since 2020 the California Energy Commission’s Title 24 Building Energy Efficiency Standards have required solar on most new single-family homes and low-rise multifamily buildings, and the 2022 update adds battery storage and electric-ready measures for many new buildings (California Energy Commission, as of 2026). If you own an existing home, you are not required to add solar; the mandate applies to new construction and, in some cases, major renovations. So a newly built California home may already be solar-ready, while retrofitting an existing home stays your choice.
Does California have a solar tax credit or raise my property taxes?
California has no statewide residential solar income-tax credit (DSIRE, as of 2026). It does offer a property-tax benefit: under the Active Solar Energy System Exclusion, a qualifying solar system is not added to your home’s assessed value, so it does not raise your property taxes, an exclusion currently scheduled to sunset January 1, 2027 unless the legislature extends it again (CA BOE, as of 2026). The federal residential credit (Section 25D) is separate, and it ended for systems placed in service after December 31, 2025, so it is not available to 2026 buyers either (IRS, as of January 1, 2026). The main state-level benefit is that property-tax exclusion, alongside net billing and SGIP for storage.
What happened to the federal solar tax credit?
The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act, so a California homeowner who buys solar in 2026 cannot claim it (IRS, as of January 1, 2026). A separate commercial credit, Section 48E, can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner. California net billing, the property-tax exclusion, and SGIP were not affected, so the in-state case for solar still holds.
Can I get solar in California with no up-front cost?
Some homeowners can, through a lease or power purchase agreement (PPA) where eligible, which can mean no out-of-pocket cost at installation in exchange for monthly payments. This is not free solar; it is a long-term agreement, often 20 to 25 years, and total payments may exceed the cost of a cash purchase. On a lease or PPA the third-party owner, not you, keeps any owner-level incentive, while your benefit is a lower or fixed power price. If you want to own the system and capture the benefits yourself, a cash purchase or solar loan keeps them with you. Check what you qualify for before deciding.
