Solar Financing Options in 2026: Loan vs. Lease vs. PPA vs. Cash
Going solar is a big purchase, and almost nobody pays for it the same way. In 2026 you have four main paths: pay cash, take a solar loan, sign a lease, or sign a power purchase agreement (PPA). Each one changes who owns the system, who gets the financial perks, and how much you actually save.
This guide breaks down all four in plain language so you can pick the one that fits your budget and goals — and avoid the fine print that trips homeowners up.

The One Thing That Changed Everything in 2026
For over a decade, most homeowners who bought solar claimed the 30% federal residential solar tax credit (Section 25D). That credit expired on December 31, 2025 under the One Big Beautiful Bill Act. If your system is installed on or after January 1, 2026, you cannot claim the 30% federal credit on your personal taxes.
There's one important nuance. A separate federal credit for businesses — the Section 48E commercial credit — is still available at 30% through 2027. You don't qualify for it as a homeowner who buys your own system. But the company that owns a leased or PPA system can claim it, which is part of why $0-down lease and PPA offers still exist in 2026. The savings reach you indirectly through their pricing, not as a check or a credit on your tax return.
Bottom line: how you pay now determines whether any federal benefit touches your project at all. That makes choosing the right financing option more important than ever. (For the full picture, see our 2026 solar tax credit guide and 2026 incentives guide.)
The Four Ways to Pay for Solar
1. Cash Purchase
You pay the full system cost upfront and own everything from day one.
- Typical cost: A residential system averages about $3.00 per watt installed in 2026, with most quotes between $2.50 and $3.50 per watt. A common 8 kW system runs roughly $20,000–$28,000 before any incentives.
- Best for: Homeowners who have the cash and want the lowest lifetime cost and highest long-term savings.
- Upside: No interest, no monthly payment, you keep 100% of the bill savings, and you own an asset that can add home value.
- Downside: Large upfront outlay. And in 2026 a cash buyer gets no federal tax credit — so payback depends on your electricity rates, state/utility incentives, and net metering, not a federal rebate.
2. Solar Loan
You borrow the system cost and pay it back over time. You still own the system, just like a cash purchase.
- Typical rates: Solar loan APRs in mid-2026 commonly fall around 6%–9%, though offers range lower and higher depending on credit score, lender, and loan type. Some states also run low-interest clean-energy or PACE loan programs.
- Best for: Owners who want the benefits of buying without paying everything upfront.
- Upside: Little or no money down, you own the system, and the monthly payment often replaces (or beats) your old electricity bill.
- Downside: You pay interest, so total cost is higher than cash. Watch for "dealer fees" baked into low-APR offers, and compare the APR and total interest — not just the monthly payment.
3. Solar Lease
A third-party company owns the system and installs it on your roof. You pay a fixed monthly payment to use it.
- How it works: Your payment is the same each month no matter how much power the panels produce. Many 2026 leases include an annual escalator — typically 0.99%, 1.99%, or 2.99% — that raises your payment a little each year.
- Best for: Homeowners who want lower bills with little or no upfront cost and don't want to own or maintain equipment.
- Upside: $0-down options are common and maintenance is the provider's responsibility.
- Downside: You don't own the system, so you don't get the ownership perks, and the provider claims any federal/commercial credit. Leases can also complicate a future home sale.
4. Power Purchase Agreement (PPA)
Like a lease, a third party owns the system. The difference: instead of a fixed payment, you pay per kilowatt-hour for the electricity the panels actually produce — usually at a rate below your utility's.
- How it works: Your bill rises and falls with production. Many PPAs also carry an annual escalator (commonly 0.99%–2.99%). Lease and PPA contracts often include a buyout clause after year 5, 7, or 10 if you later want to own the system.
- Best for: Homeowners who want to pay only for what the system generates and prefer predictable per-kWh pricing below the utility rate.
- Upside: Often $0 down, no maintenance worries, and you only pay for power produced.
- Downside: Same as a lease — no ownership, no direct tax benefit, and escalators can erode savings over a long contract.

|---|---|---|---|---|
| Who owns the system? | You | You | Provider | Provider |
| Upfront cost | High | Low / $0 | Usually $0 | Usually $0 |
| Monthly payment | None | Fixed loan payment | Fixed | Per kWh produced |
| Federal tax benefit to you (2026) | None | None | None (provider claims 48E) | None (provider claims 48E) |
| Lifetime savings | Highest | High | Lower | Lower |
| Maintenance | You | You | Provider | Provider |
| Adds home value | Yes | Yes | Not typically | Not typically |
Why Ownership Is the Deciding Factor Now
In 2026, the single biggest fork in the road is ownership.
- Own it (cash or loan): You capture all the electricity-bill savings, any state or utility incentives you qualify for, net-metering credits, and potential home-value gains. You're also responsible for upkeep.
- Don't own it (lease or PPA): You trade those long-term perks for low upfront cost and a hands-off experience. The provider keeps the incentives — including the 30% commercial 48E credit — and you get cheaper power than the utility.
There's no universally "right" answer. If maximizing lifetime savings is the goal and you can afford it, owning wins. If keeping cash in your pocket and avoiding maintenance matters more, a lease or PPA can still make sense.
How Net Metering Affects Every Option
No matter how you pay, net metering is a major driver of your savings. It's the policy that credits you for the excess power your panels send back to the grid.
As of 2026, roughly 38 states plus D.C. offer some form of net metering, but about a third of states have reduced or revised the traditional one-to-one retail credit. States like Massachusetts, New York, and New Jersey still offer strong full-retail credit, while others (such as California and Nevada) have shifted to lower-value net billing. Most states include a grandfather clause that locks in your rate for 10–20 years once your system is approved — so the rules in place when you connect matter a lot. Where export rates have dropped, adding a battery is now the standard way to protect savings.
Which Option Is Right for You?
- Have the cash and want the best lifetime return? Buy with cash.
- Want ownership without the upfront hit? Take a solar loan — just compare APR and total interest, not the monthly payment alone.
- Want $0 down and zero maintenance, and you're comfortable not owning? Consider a lease or PPA, and read the escalator and buyout terms closely.
The cleanest next step is to get an actual quote for your home and roof. Real numbers — your electricity rate, your sun exposure, your state's incentives — beat any national average. See our 2026 cost guide and is-solar-worth-it breakdown for the full picture.
Frequently Asked Questions
Is there still a federal solar tax credit for homeowners in 2026?
No. The 30% Section 25D residential credit expired December 31, 2025. Systems installed on or after January 1, 2026 don't qualify. The 30% commercial 48E credit runs through 2027, but only the business that owns a leased or PPA system can claim it — not a homeowner who buys. See our 2026 tax credit guide.
What's the difference between a solar lease and a PPA?
A lease is a fixed monthly payment to use the system; a PPA charges per kilowatt-hour for the power produced, usually below your utility rate. In both, a third party owns the equipment.
Is it better to buy or lease solar in 2026?
Buying (cash or loan) gives the most lifetime savings and keeps all incentives and home-value benefits, but you handle maintenance. Leasing or a PPA means low or no upfront cost and a hands-off experience, with lower long-term savings.
What are solar loan interest rates right now?
In mid-2026, APRs commonly fall around 6%–9%, varying by credit, lender, and loan type. Compare the APR and total interest, and watch for dealer fees in very low advertised rates.
How much does a solar system cost in 2026?
About $3.00 per watt installed on average ($2.50–$3.50 typical); a common 8 kW system is roughly $20,000–$28,000 before incentives. See the cost guide.
Do leases and PPAs have annual price increases?
Often yes — many include an annual escalator of 0.99%, 1.99%, or 2.99%. A no-escalator contract usually saves more over the full term, so check this before signing.
