Best Solar Financing Options for Homeowners in 2026 — Loans, Leases, and PPAs Compared

Correction (2026-07-28): This article originally stated that cash and loan-financed solar purchases still receive the 30% federal tax credit in 2026. That is no longer true. The residential credit (Section 25D) expired for any system placed in service after December 31, 2025, under the One Big Beautiful Bill Act (OBBBA). Whether you pay cash, take a solar loan, or use a HELOC, a system installed in 2026 does not qualify for a federal credit. The math and comparisons below have been corrected to reflect that.

Bottom line up front: A $25,000 solar system now costs $25,000 out of pocket, whether you pay cash or finance it — there is no federal tax credit for owned residential systems installed in 2026. That changes the math on every financing path below, but it doesn't erase the case for ownership: you still avoid a lease's long-term markup and you still capture 100% of your electricity savings and any home-value increase. For most homeowners, a solar-specific loan through GoodLeap or Mosaic offers the right combination of $0 down and full ownership. Cash is better if you have the capital and don't need the liquidity elsewhere. Avoid PACE financing unless you've exhausted every other path.

The solar industry knows something homeowners often don't: how you pay for solar matters almost as much as which panels you install.

A homeowner who finances at 7.99% APR over 25 years will pay roughly 40% more than one who takes a 10-year loan at the same rate. A homeowner who signs a solar lease might save $20/month today but forfeit $10,000–$30,000 in lifetime value versus ownership. And with the federal tax credit for owned systems now gone, a homeowner who doesn't re-run their payback math for 2026 could commit to a system priced as if $7,500 were still coming back — money that no longer exists.

This guide walks through every major solar financing path available to US homeowners in 2026 — what each costs, what you give up, and which option fits which situation.

All 6 Solar Financing Options Compared

Before the deep dives: a side-by-side view.

|---|---|---|---|---|---|

| Solar-specific loan | $0 | Yes | No (expired 1/1/26) | 5.99–9.99% | Best for most homeowners |

| PPA | $0 | No | No — same as lease | Per-kWh rate | Risk-averse, variable savings OK |

| PACE financing | $0 | Yes | No (expired 1/1/26) | 8–12%+ | Last resort only |

APR ranges as of June 2026. Your rate depends on credit score, term length, and lender. Installed prices vary significantly by state and system size. The 30% residential Investment Tax Credit (Section 25D) expired for systems placed in service after December 31, 2025 — it no longer applies to any ownership path, regardless of how you pay.

Option 1: Cash Purchase — Best ROI, Highest Barrier

If you have $15,000–$35,000 in savings or accessible brokerage funds, a cash solar purchase is a genuine financial decision — not an obvious one.

What you get: Full ownership from day one. You collect all available state rebates and net metering credits your utility offers, and own an asset that transfers with the home at sale. You do not get a federal tax credit — the 30% residential Investment Tax Credit expired for any system placed in service after December 31, 2025.

The math: With no federal credit, a $25,000 system has a net cost of $25,000. If it saves you $1,800/year on electricity (a typical result for a 10–12 kW system in a moderate-sun state), your simple payback period is roughly 14 years — several years longer than it would have been under the old 30% credit. Solar panels carry 25-year performance warranties, so you'd still see 10+ years of effectively free electricity after payback, but the return is meaningfully lower than pre-2026 marketing math suggests.

What you give up: Liquidity, and — compared to a year ago — a materially longer payback period now that the credit is gone. Whether $25,000 is better deployed into solar or a diversified investment depends more than ever on your utility's rate trajectory and how long you plan to stay in the home.

One important detail: Some installers and ads may still quote pricing "after the 30% tax credit." That pricing no longer applies to residential purchases in 2026. If anyone quotes you a net price assuming the credit, ask them to show you the gross price and confirm in writing that no federal credit applies.

Best for: Homeowners with available capital and a long-term horizon in the home. Payback is strongest in states with high electricity rates (California, Massachusetts, Hawaii) and available state incentives, which OBBBA did not touch.

Option 2: Solar-Specific Loans — Best Balance for Most Homeowners

Solar loans are now the most common way US homeowners finance solar, and the case is straightforward: $0 down and full ownership — though as of 2026, ownership no longer comes with a federal tax credit attached.

The largest solar loan originators — GoodLeap, Mosaic, and Sunlight Financial — work directly through solar installers. Qualified buyers typically see rates between 5.99% and 9.99%, with terms from 10 to 25 years.

How it works: Your installer offers solar financing at the point of sale, often with same-day approval. The lender pays the installer directly; you make monthly payments to the lender. You own the panels from installation day, but there is no ITC to apply toward the balance — that credit expired for systems placed in service after December 31, 2025.

What changed: Before 2026, homeowners financing at $25,000 with a 20-year term could plan on a $7,500 ITC arriving at tax time and use it as a lump-sum principal paydown, cutting the effective loan balance meaningfully in year one. That strategy no longer works for systems installed in 2026 — there's no credit to apply. If a lender or installer pitches a "step-down" payment structure built around a tax credit landing in year one, ask exactly which credit they mean and confirm it still exists before you sign; for residential ownership, it doesn't.

What to watch for:

Dealer fees. Solar lenders charge installers a fee of 10–30% of the loan value to offer financing. Installers often bury this in the system price, not the loan terms. Ask for the system's cash price before accepting a financing quote. If the financed price is more than 12–15% higher, negotiate or compare quotes from other installers.

Loan term. A 25-year solar loan at 7.99% on a $20,000 balance costs about $18,400 in total interest — more than the system itself. A 10-year term at the same rate cuts that to $8,700. The monthly payment is higher, but the lifetime cost is dramatically better. Run both scenarios before you sign.

Prepayment penalties. Some lenders charge fees for early payoff. Since you'll want to apply your ITC refund to principal in year one, this clause matters. Read it before signing.

Lender breakdown:

GoodLeap is the largest US solar loan originator, covering all 50 states with the widest installer network and rapid approval. Best for: broad availability and installer-facing ecosystem.
Mosaic competes closely, with slightly more competitive rates for top-credit borrowers and a strong mobile experience. Best for: 720+ credit score buyers who comparison-shop.
Sunlight Financial (now under CF Bancorp) offers more flexibility on non-standard deal structures. Best for: installers that already work in their network.

Best for: Homeowners with 680+ credit scores who want $0 down and full ownership with the ITC intact. This is the right call for the majority of the residential solar market.

Option 3: Home Equity Loan or HELOC — Lowest Rate, Requires Equity

If you've built significant equity in your home, borrowing against it for solar typically unlocks rates 1–2 percentage points below solar-specific loans — and that spread compounds over a 10–15 year payoff period.

Home equity loan: Fixed rate, lump sum at closing, fixed monthly payment for the life of the loan. Good for knowing exactly what solar will cost you and locking in today's rate.

HELOC: Variable rate tied to the prime rate, revolving credit line you draw as needed. Better if you're phasing an install — solar panels now, battery storage in 18 months, EV charger next year — because you only pay interest on what you've drawn.

What you get: Full system ownership, all state rebates, and net metering rights — but no federal tax credit; that expired for residential systems placed in service after December 31, 2025, regardless of financing method. Interest paid on home equity debt used for home improvements may still be deductible (consult a tax advisor — deductibility depends on your total itemized deductions and loan balance limits).

The rate advantage over time: On a $20,000 loan, the difference between 6.25% (HELOC) and 8.49% (solar loan) over 12 years is about $2,600 in total interest. Real savings, though not transformative. The math gets more compelling on large systems or longer loan terms.

What you give up: Your home is collateral. A solar-specific loan puts your panels at risk if you default; a HELOC puts your house at risk. Most homeowners who can afford a HELOC aren't in real default risk, but it's a meaningful distinction worth acknowledging.

Best for: Homeowners with 720+ credit and $50,000+ in accessible equity. Particularly good for bundling solar, battery, and EV charging into a single HELOC draw rather than stacking separate loan products.

Option 4: Solar Lease — Lowest Commitment, Lowest Long-Term Return

A solar lease means a company installs panels on your roof, owns them, and charges you a flat monthly fee to use the electricity they generate. That fee is set below your current utility bill, so you save something from day one without putting any money down.

Leases are available through Sunrun and several regional installers.

What you get: No down payment, no credit score bar (qualification is easier than for loans), no maintenance responsibility. If the panels underperform their guaranteed production, the installer typically compensates you. The monthly payment is predictable.

What you give up:

State rebates. Most go to the system owner — the installer, not you.
Net metering credits. Lease agreements vary; some pass through excess generation credits, many don't. Read your specific terms.
Home sale flexibility. Leases transfer with the home, which can complicate real estate transactions. Some buyers don't want to assume a 20-year lease obligation. Sellers have been known to pay out the remaining lease balance at closing to simplify the sale.
Long-term upside. Solar lease payments are typically fixed or have small annual escalators (1–3%). If electricity rates rise 4–5% annually — as they have in most US markets over the past decade — your savings don't compound the way they do when you own the system.

Note what's changed for 2026: leasing used to mean trading away the 30% ITC, which was the single biggest financial argument for ownership. That trade no longer exists — owners don't get a federal credit either now. The case for ownership over leasing still holds (you keep 100% of savings and any home-value increase, rather than a discounted lease payment), but it's a smaller gap than it was a year ago.

The honest long-term math: A homeowner who buys a $25,000 system with no federal credit and saves $1,800/year achieves payback in roughly 14 years, then enjoys free electricity for the remaining warranty period. A homeowner who leases saves $300–$600/year for 20–25 years and never builds equity in the system. Over a 25-year horizon, ownership still typically generates more total value than leasing — but the gap is narrower than pre-2026 comparisons showed, since neither path gets a federal credit anymore.

When leasing makes sense: If you can't qualify for a solar loan and can't access home equity, a lease still beats paying full retail electricity for 25 years. It's the right answer in that scenario. Enter it knowing you're trading long-term value for short-term simplicity — and knowing that trade no longer involves giving up a tax credit ownership doesn't have either.

Best for: Homeowners with limited credit access, high debt-to-income ratios, or low federal tax liability who still want to reduce their electricity bill without upfront cost.

Option 5: Power Purchase Agreement (PPA) — Pay by the Kilowatt-Hour

A PPA resembles a lease structurally — you don't own the system — but instead of a fixed monthly fee, you pay a per-kWh rate for the electricity the panels actually produce. That rate starts below your utility rate and typically escalates 1–3% per year.

Sunrun and Tesla Energy offer PPAs in eligible states.

The appeal: On low-sun months, your PPA bill drops because you're paying for actual production. On high-sun months, you generate more and your bill rises — but still at a rate below utility pricing. You're shielded from volatile utility pricing while retaining some variability in your solar bill.

The escalator risk: That 1–3% annual rate increase compounds. If your PPA starts at $0.10/kWh and escalates 2.5% annually, you'll be paying $0.18/kWh at year 25. If your utility rate holds flat or drops — not common, but possible in deregulated markets or areas with new generation coming online — you could end up at or above retail in the later years of your agreement.

Geographic availability: PPAs are currently legal in approximately 30 states. Some large solar markets have utility lobbying that restricts third-party ownership arrangements. Check your state's status before counting on this option.

What you give up: The same as a lease — tax credits, rebates, system ownership — plus a payment structure that's harder to budget for month to month.

Best for: Homeowners who want solar savings without fixed monthly commitment and are comfortable with variable (though still lower-than-utility) electricity costs. Second-choice to leasing for credit-limited buyers.

Option 6: PACE Financing — Last Resort Only

Property Assessed Clean Energy (PACE) financing lets you borrow for solar with repayments attached to your property tax bill rather than your credit profile. Because the loan is secured by the property itself rather than your creditworthiness, approval is accessible to homeowners with poor credit who have significant home equity.

What you get: No credit score requirement and full system ownership. No federal tax credit is available regardless — the residential ITC expired for systems placed in service after December 31, 2025.

What to know before signing anything:

PACE financing has drawn scrutiny from the Consumer Financial Protection Bureau and multiple state attorneys general for aggressive marketing and opaque terms. Key risks:

High rates. PACE rates typically run 8–12%+, well above solar-specific loans.
Senior lien position. In many states, PACE assessments take senior position to your mortgage in certain default scenarios. This can complicate refinancing and sales, and has led to foreclosure disputes.
Hard to exit. Unlike a conventional loan you can refinance out of at any time, PACE assessments are attached to the property and can be difficult to remove before a sale or refi.

California, Florida, and several other states have passed consumer protection rules around PACE disclosures. Read every line — not a summary from the installer — before proceeding.

PACE is genuinely a last resort. If you have strong home equity but credit that disqualifies you from every loan product, and you've seriously compared the lifetime cost of a lease or PPA versus PACE ownership, PACE may still pencil out. But it requires eyes-open analysis, not a quick signature at the kitchen table.

Best for: Homeowners with strong equity, poor credit, who are committed to ownership and have fully reviewed all PACE terms and state-specific rules.

Why There's No Federal Tax Credit for Ownership in 2026

For homeowners going solar before 2026, the residential Investment Tax Credit (Section 25D) let you deduct 30% of your total system cost from your federal income taxes — a dollar-for-dollar reduction in your tax bill, not a deduction against taxable income. For a $25,000 system, that was a $7,500 credit.

That credit no longer exists for new residential purchases. The One Big Beautiful Bill Act (OBBBA), signed into law in July 2025, moved up the expiration of Section 25D so that it terminates for any system placed in service after December 31, 2025. It had previously been scheduled to run at 30% through 2032 before stepping down. That phase-down schedule is now irrelevant — the credit is gone entirely for homeowner-owned systems, not reduced.

Key facts for 2026:

Cash, solar loans, and HELOCs — every path where the homeowner owns the system — no longer qualifies for any federal residential tax credit
If you placed a system in service on or before December 31, 2025, and already claimed the 30% credit, that claim stands and any unused portion still carries forward — this change is not retroactive
A separate commercial credit (Section 48E) still exists for project owners — typically the leasing company in a lease or PPA structure — but the homeowner does not receive it directly, and eligibility depends on the project meeting specific construction-timing rules
State tax credits, rebates, SRECs, and property tax exemptions were not touched by OBBBA and remain available in many states

If you're comparing quotes and an installer's pricing or payback math still assumes a 30% credit for a cash or loan purchase, that math is wrong for any system installed in 2026 — ask them to re-run it without the credit.

Which Path Fits Your Situation?

Run through this decision sequence:

Do you have $15,000–$35,000 available and want the best long-term return? → Cash purchase. No federal credit either way, but you avoid financing costs entirely.

Do you have 680+ credit and manageable debt-to-income? → Solar-specific loan via GoodLeap or Mosaic. Covers the majority of homeowners.

Do you have 720+ credit and $50,000+ in home equity? → Home equity loan or HELOC for the lowest rate, especially useful for bundled installs.

Is your credit limited or your debt-to-income high? → Solar lease via Sunrun. You still reduce your electricity bill, and you're no longer giving up a federal credit that owners don't get either.

Do you prefer to pay per kilowatt-hour produced rather than a fixed fee? → PPA where available.

Have you been turned down for every option above and have strong home equity? → PACE financing with a full eyes-open review of terms.

Five Questions to Ask Before You Sign

Solar installers are often financially incentivized to push their preferred lender. Get answers to these before committing:

What is the cash price versus the financed price? The gap reveals the dealer fee embedded in the loan offer. Anything over 12% warrants a direct conversation or competing quote.

Can I pay off this loan early without penalty? You'll want to apply your ITC refund to principal in year one.

What happens to the loan or lease if I sell my home? Solar loans typically pay off at closing; leases transfer to the buyer or require buyout. Know which you're signing.

What is my actual APR, including all origination fees? Not the promotional floor rate — your rate, with your credit profile.

Who services this loan after closing? Solar loans are frequently originated and then sold to servicers. Knowing who you'll actually be writing checks to matters for long-term planning.

The Bottom Line on Solar Financing in 2026

The best solar financing is the one that gets you to ownership at the lowest total cost. For most homeowners, that's a solar-specific loan through GoodLeap or Mosaic — $0 down and full ownership, though with no federal tax credit factored in, expect a payback path closer to 13–15 years rather than the 10-12 years common under the old 30% credit.

If you have the equity and the credit, a home equity loan saves real money on interest. If you have the capital, cash is the cleanest path.

Leases and PPAs have a legitimate place for homeowners who can't qualify for financing. The math no longer favors ownership by as wide a margin as it did before 2026, since neither path gets a federal credit now — but ownership still typically wins over a 25-year horizon.

Do the math on both paths before you commit, using 2026 numbers — not a payback calculation that still assumes a tax credit that no longer applies.
