Cash still delivers the strongest 25-year savings for California homeowners who have the capital. A solar loan gets you the same ownership benefits with $0 down. A lease or PPA has become genuinely more competitive in 2026 because leasing companies can still claim a 30% commercial tax credit that homeowners can no longer claim themselves. There’s no universally correct answer; it depends on your capital, your credit, how long you’ll stay in the home, and your utility.
If you’ve been researching solar in California in 2026, you’ve probably noticed the financing conversation has changed. The 30% federal residential Investment Tax Credit that shaped solar economics for over a decade expired on December 31, 2025. Every solar financing guide written before 2026 is now at least partially out of date.
Here’s what that means in plain terms:
- Cash and loan buyers no longer receive a federal tax credit.
- Lease and PPA providers, who own the system and qualify as commercial operators, can still claim the commercial ITC under Section 48E through at least 2027, and they pass that value to homeowners through lower monthly rates.
This guide gives you the honest post-ITC analysis for California homeowners: what each option actually costs, who each one is right for, and how manufacturer-backed financing fits into the picture.
The comparison at a glance
| Cash | Loan | Lease / PPA | |
|---|---|---|---|
| Upfront cost | Full system cost | $0 down | $0 down |
| Who owns the system | You | You | The provider |
| Federal tax credit | None (residential ITC expired 12/31/2025) | None | Commercial ITC (30%), captured by the provider and partly passed through |
| Property tax exclusion | Yes | Yes | Usually no, depends on the agreement |
| Monthly payment | None | Fixed loan payment | Fixed lease payment or per-kWh PPA rate, often with a 1 to 3% annual escalator |
| Approx. payback | 7 to 11 years | 9 to 13 years | N/A (no ownership to pay back) |
| 25-year savings (10 kW system, LADWP rates) | ~$176,000 | Slightly lower than cash, minus interest paid | 30 to 50% lower than owned paths |
| Adds home resale value | Yes | Yes | Usually not |
| SGIP battery rebate eligibility | Yes, if you own the battery | Yes, if you own the battery | Usually flows to the provider |
| Best for | Homeowners with available capital, staying 15+ years | Homeowners who want ownership without upfront cash | Homeowners with limited tax liability, moving in 5 to 7 years, or who want zero maintenance |
Why the financing decision matters more under NEM 3.0
Two policy changes hit California at the same time, and together they make this decision more consequential than it was even two years ago.
The ITC expired, and NEM 3.0 arrived together
What changed:
- California’s Net Billing Tariff (NEM 3.0) took effect for SCE, PG&E, and SDG&E customers in April 2023, cutting solar export credits by roughly 75%.
- That made battery storage close to essential for SCE homeowners to capture full solar value. A battery adds $10,000 to $15,000 to a system cost.
- The residential ITC expired December 31, 2025, removing a $6,000 to $10,000 tax credit that used to make loan and cash purchases clearly more attractive than leasing.
The result: the after-tax cost of a cash or loan purchase is higher than it was in 2024, while leasing companies (which still claim the commercial ITC) now offer a genuinely more competitive alternative than they did when homeowners could claim the residential credit themselves.

The property tax exclusion adds a 2027 deadline
California’s property tax exclusion, which prevents your home’s assessed value from rising when you add solar, expires for new systems after January 1, 2027.
| Applies to | |
|---|---|
| Cash purchase | Yes |
| Loan purchase | Yes |
| Lease (provider retains ownership) | Usually no, depends on the specific agreement |
For owned systems, this saves roughly $300 to $600 a year depending on your local tax rate and system size, or $6,000 to $12,000 over 20 years. That’s a real reason to compare owned versus leased paths before the deadline rather than after.
Cash purchase: the strongest long-term return
Paying cash delivers the best 25-year financial outcome for homeowners who have the capital available.
What it costs and returns in 2026:
- A typical 10 kW system in Los Angeles runs $23,700 to $32,000 installed before incentives (see the full solar install cost estimate for Los Angeles for a size-by-size breakdown). Without the residential ITC, that’s the full out-of-pocket cost.
- At current LADWP rates of $0.225 per kWh with full retail-rate net metering, a 10 kW Qcells system saves approximately $2,700 to $3,200 a year in year one, growing as LADWP rates rise roughly 4% annually.
- Payback runs 7 to 11 years (see how the payback period is calculated), after which 14 to 18 years of the panel’s warranted life are pure savings.
- Over 25 years, a cash-purchased 10 kW system in LADWP territory projects average lifetime savings of approximately $176,000, the strongest outcome of any path.
Choose cash if you:
- Have liquid capital you aren’t actively deploying elsewhere
- Plan to stay in the home 15 or more years
- Want the simplest possible relationship with your system, with no ongoing payments
- Are in LADWP territory, where full retail-rate net metering maximizes every kWh
Solar loan: ownership without upfront capital
A solar loan gives you system ownership and the long-term benefits of a cash purchase without requiring upfront capital.
How it typically works:
- $0 at signing, with ownership from day one
- Loan terms from 10 to 25 years, minimum credit score around 600
- Pre-qualification uses a soft credit pull that doesn’t affect your score
- First payment due roughly 30 days after Permission to Operate, so your system is already saving you money before any bill arrives
- No lien on your home; the lender files a UCC-1 Financing Statement against the equipment itself, leaving your home’s title and mortgage untouched
- Financing through a manufacturer-backed lender can extend your panel warranty. See the Qcells panel review for how the standard 25-year warranty compares to the 30-year version available through EnFin financing
The dealer fee warning most guides skip:
Many solar loans include a dealer fee, a percentage of the loan amount the installer pays the lender to subsidize a low advertised APR. These fees run 15 to 30 percent of the financed amount and are typically rolled into the system price without being called out.
| What you see | What it might mean |
|---|---|
| A system quoted at $28,000 on “low APR financing” | Cash price might be $22,000; the $6,000 gap is a dealer fee |
Always ask for both numbers: the cash price and the financed price. If they differ by more than a few percent, a dealer fee is built in.
Choose a loan if you:
- Want ownership and its long-term benefits without a large upfront check
- Qualify for the property tax exclusion and want to capture it before January 1, 2027
- Can accept a payback timeline of roughly 9 to 13 years, after which savings are unencumbered by payments
Solar lease and PPA: the 2026 commercial ITC advantage
This is the path that got genuinely more competitive in 2026, and the reason has everything to do with the ITC expiration.
Why leasing companies now have a tax advantage homeowners don’t
| Buyer type | ITC status in 2026 |
|---|---|
| Homeowner (cash or loan) | Residential ITC is 0% as of January 1, 2026 |
| Leasing company (retains ownership) | Commercial ITC under Section 48E remains at 30% through at least 2027 |
The practical effect: a homeowner who buys a $28,000 system pays $28,000. A leasing company installing the same system claims $8,400 in commercial ITC and can offer a monthly rate reflecting a system cost of roughly $19,600. That gap didn’t exist when homeowners could claim the residential ITC themselves.
What you give up with a lease or PPA
- No ownership. A leased system doesn’t add to your home’s resale value the way an owned system does. See the full breakdown of how solar affects home value for owned versus leased systems.
- Selling complications. When you sell, the lease either transfers to the buyer (which some buyers resist) or you pay a buyout that can include a premium above remaining payments.
- No property tax exclusion in most lease structures, since the provider retains ownership.
- Lower long-term savings. Over 25 years, owned systems consistently deliver 30 to 50 percent more total financial benefit than leased systems.
- Watch for escalator clauses. Many PPA contracts include 1 to 3 percent annual rate increases. A PPA starting at $0.20 per kWh with a 2.5 percent annual escalator reaches $0.37 per kWh by year 25, potentially approaching your utility rate.
Choose a lease or PPA if you:
- Have limited tax liability, making the residential ITC largely irrelevant to you anyway
- Want zero maintenance responsibility
- Plan to move within 5 to 7 years and prefer not to manage a loan transfer at sale
- Can’t qualify for a solar loan at acceptable terms
Does financing method affect battery storage decisions under NEM 3.0?
Yes, meaningfully. For SCE homeowners under NEM 3.0, battery storage is close to required to capture full solar value.
| Financing path | Who owns the battery | SGIP rebate (approx. $150/kWh) |
|---|---|---|
| Loan | You | Goes to you |
| Cash | You | Goes to you |
| Lease/PPA with battery included | The provider | Usually flows to the provider; confirm any pass-through explicitly before signing |
For a full walkthrough of how financing and ownership interact with battery incentives, see how the solar battery tax credit works. For LADWP homeowners, where battery storage is optional rather than required, the financing decision for battery follows the same logic as for panels: ownership delivers better long-term returns, while leasing offers simpler maintenance and zero upfront cost. The solar and battery bundle estimator shows combined savings and payback across solar and battery together.
What to check before choosing any financing path
Two checks apply no matter which path you pick.
1. Roof age and condition. A solar system lasts 25 years; a lease or PPA runs 20 to 25 years. Installing on a roof that needs replacement in 7 years means removing and reinstalling the system, at $3,000 to $8,000, partway through a contract. Read: Is your roof ready for solar before signing any agreement, regardless of which financing path you choose.
2. Cash price vs. financed price. Ask for both, separately, before signing any solar loan. If the financed price is more than 5 percent above the cash price, a dealer fee is embedded in the loan.
The right path depends on your specific situation
There’s no single correct answer to cash vs. loan vs. lease in California in 2026. The right path depends on:
- How long you plan to stay in the home
- Whether you have capital available
- Your credit profile
- How much you value system ownership
- Which utility serves your home
What’s true for every California homeowner is that staying on utility power, paying SCE’s or LADWP’s rising rates with no solar offset, is the most expensive path in every scenario modeled over 25 years. If you’re still weighing whether to go solar at all under current rules, our breakdown of whether solar is worth it in California after NEM 3.0 is the right place to start before you compare financing paths. The financing structure determines how you get to solar savings. All three paths get you there. Run your own numbers with the California solar savings calculator before you commit to any one path.
Frequently asked questions
Is cash still the best way to go solar in California after the ITC expired?
Cash still delivers the strongest 25-year financial outcome for homeowners with available capital. The gap between cash and lease has narrowed in 2026 because leasing companies can still claim the 30% commercial ITC while residential cash buyers cannot. For homeowners without liquid capital or with limited tax liability, a lease or loan is now more competitive than it was in 2024.
Can I still get $0 down solar in California in 2026 without the federal tax credit?
Yes. Solar loans require $0 down, with the first payment due after Permission to Operate. Leases and PPAs also require $0 down. PACE financing offers a third no-money-down path tied to your property tax bill, though it places a lien on your home and can complicate refinancing.
Does a solar lease add value to my home in California?
Generally no. When the leasing company retains ownership, the installation doesn’t add to your home’s assessed or appraised value the way an owned system does. An owned system typically adds $15,000 to $25,000 in home value for a properly sized LA installation, a meaningful difference if you plan to sell within 10 to 15 years.
What is the property tax exclusion, and does it apply to leased solar in California?
It prevents a solar installation from triggering a reassessment of your home’s value. It applies to owned systems (cash and loan) where you hold title to the equipment. Leased systems where the provider retains ownership may not qualify, depending on the agreement structure. It expires for new installations after January 1, 2027.
What is the difference between a solar loan and a solar PPA in California?
A loan makes you the owner from day one; you receive all production benefits, the system adds to home value, and after payback, the savings are entirely yours. A PPA means the provider owns the system and you pay a per-kWh rate. PPAs offer lower upfront cost and no maintenance responsibility but deliver lower long-term savings and don’t add to home value.
