Solar Lease vs PPA vs Buy in 2026: Best Way to Go Solar Without the Tax Credit

Last updated: March 9, 2026

Here is the reality most solar shoppers face in 2026: the 30% federal solar tax credit that homeowners relied on for nearly two decades is gone. The One Big Beautiful Bill (OBBBA), signed on July 4, 2025, terminated the Section 25D Residential Clean Energy Credit for any system placed in service after December 31, 2025. That means if you install solar panels on your roof in 2026, you will not get a dime back from the IRS.

But solar is far from dead. In fact, more Americans are going solar in 2026 than ever before. The difference is how they are doing it. Without the tax credit as a personal deduction, the economics have shifted dramatically toward third-party ownership models — leases, power purchase agreements (PPAs), and a new hybrid called the prepaid lease. Meanwhile, cash purchases still make financial sense for some homeowners, just with a longer payback timeline.

This guide breaks down every option so you can figure out which one actually saves you the most money in 2026.

Why Everything Changed in 2026

For years, the standard advice was simple: buy your solar panels, claim the 30% federal tax credit on Form 5695, and enjoy free electricity for decades. A $20,000 system effectively cost $14,000 after the credit. The math worked beautifully.

Then Congress passed the One Big Beautiful Bill, and the residential clean energy credit (Section 25D) was terminated for installations after December 31, 2025. The credit was originally extended through 2034 under the Inflation Reduction Act, so this was nearly a decade earlier than anyone expected.

What survived? The commercial Investment Tax Credit (Section 48E) still exists for business entities. Solar installation companies that own the panels on your roof are businesses. They can still claim the tax credit — and pass part of those savings to you through lower lease rates and PPA prices. That is why third-party ownership has become the dominant model in 2026.

To be clear about the numbers:

This single change flipped the economics. Previously, owning was almost always better than leasing. Now, leasing is often the smarter financial move.

Your Four Options for Going Solar in 2026

Before we dive into each option, here is the high-level comparison. We will use a typical 8 kW residential system as our baseline, which costs roughly $20,000 to $22,000 installed at today's average of $2.58 to $2.75 per watt.

Now let's get into the details of each.

Option 1: Solar Lease

How a Solar Lease Works

With a solar lease, a third-party company installs solar panels on your roof and retains ownership. You pay a fixed monthly fee — typically $100 to $175 — for the right to use the electricity the system produces. The lease term is usually 20 to 25 years.

Because the solar company owns the system, they claim the 30% business tax credit (Section 48E) plus potential Domestic Content Bonus Credits. These savings are baked into your lower monthly rate.

Pros of a Solar Lease

• Zero upfront cost — no down payment required
• Predictable monthly payments — easier to budget than variable utility bills
• Maintenance included — the owner handles repairs, inverter replacements, and monitoring
• Day 1 savings — most leases are priced 10–30% below current utility rates

Cons of a Solar Lease

• Lower total savings than buying or prepaid leasing over the full term
• Escalator clauses — many leases increase payments 1–3% annually; over 25 years, this adds up significantly
• Complicates home sale — the buyer must either assume the lease or you need to buy out the remaining term
• No ownership equity — you are paying for energy, not building an asset

Watch Out for Escalators

This is where a lot of homeowners get burned. A lease that starts at $120/month with a 2.9% annual escalator reaches $244/month by year 25. Meanwhile, if your utility's rate increases are lower than the escalator, you could end up paying more for solar electricity than grid electricity in the later years. Always negotiate for a flat-rate lease or an escalator capped at 1.5% or less.

Option 2: Power Purchase Agreement (PPA)

How a PPA Works

A PPA is structurally similar to a lease, but instead of a fixed monthly payment, you pay a per-kilowatt-hour rate for the electricity the panels actually produce. Think of it as buying electricity from the panels on your roof instead of from the utility company — at a lower rate.

Typical PPA rates in 2026 range from $0.10 to $0.15 per kWh, compared to the national average utility rate of around $0.18 per kWh. In high-cost states like California, Massachusetts, or Connecticut, where utility rates exceed $0.25/kWh, the savings margin is even wider.

Pros of a PPA

• You only pay for what the panels produce — cloudy month? Lower bill
• Zero upfront cost
• Typically lower effective cost than leases in sunny states
• Maintenance and monitoring included

Cons of a PPA

• Seasonal variability — summer bills are higher because the system produces more energy
• Escalator risk — same issue as leases; PPA rates often escalate 1–3% annually
• Not available in every state — some states restrict or prohibit third-party PPAs (check your state regulations)
• Home sale complications — same transfer issues as leases

Where PPAs Work Best

PPAs deliver the strongest value in states with high utility rates and abundant sunshine. If you live in California, Arizona, Texas, Florida, Massachusetts, Connecticut, or New York, a PPA will likely outperform a lease on total savings because you benefit from both high production and high avoided utility costs.

Option 3: Prepaid Solar Lease — The 2026 Sweet Spot

If you have been following the solar industry closely this year, you have probably noticed a surge in prepaid lease and prepaid PPA offers. There is a reason: this model has become arguably the best deal in residential solar for 2026.

How a Prepaid Lease Works

You pay for 20 to 25 years of solar energy upfront, in a single lump sum. The solar company still owns the system — which means they claim the business tax credit and pass those savings to you in the form of a lower price. You typically pay about 70% of what a cash purchase would cost.

After a 6-year "tax credit recapture period" (the IRS requires the business to own the asset for at least 6 years to fully claim the credit), you usually have the option to take ownership of the system for $0 or a nominal fee.

Real Cost Example

Why This Model Took Off in 2026

Before the OBBBA, there was no reason for a homeowner to use a prepaid lease. You could buy the system, claim the 30% credit yourself, and end up at roughly the same net cost. Now that homeowners cannot claim the credit, the prepaid lease is the only way to benefit from the 30% ITC on a residential system. The solar company claims it, and you get the discount.

Pros of a Prepaid Lease

• 20–30% cheaper than a cash purchase for the same system
• No monthly payments
• Maintenance included for the first 6 years
• Ownership transfer option after the recapture period
• Best total return on investment among non-ownership options

Cons of a Prepaid Lease

• Still requires significant upfront capital ($12,000–$18,000)
• You do not own the system for 6 years — if you sell your home before then, transferring the agreement is more complex
• Not all installers offer this model yet — availability varies by market
• Read the fine print — some agreements charge a fee for the ownership transfer after year 6

Option 4: Cash Purchase (No Tax Credit)

Is Buying Still Worth It?

Yes, but the math is tighter. A cash purchase still generates the highest total savings over 25 years because you keep 100% of the electricity value with zero ongoing payments. The tradeoff is a longer payback period.

The Numbers Without the Tax Credit

Let's use a common scenario: an 8 kW system in a state with average sun (1,400 kWh per kW annually), a $0.18/kWh utility rate, and 2.5% annual utility rate escalation.

A 10-year payback is longer than the 7-year payback homeowners were accustomed to, but the system still generates roughly $49,000 in electricity value over its 25-year warranted life. That is a solid return on a $21,000 investment.

When Cash Purchase Still Wins

• You plan to stay in your home for 15+ years
• You want maximum total savings over the system lifetime
• Your state has net metering at full retail rate
• You do not want any third-party agreement attached to your property
• You can afford the upfront cost without stretching your finances

When to Think Twice

• If you might move within 10 years — you may not recoup the full cost
• If your state has poor net metering policies (some states credit solar exports at wholesale rates, cutting your savings significantly)
• If a prepaid lease gets you the same outcome for 30% less upfront

State Incentives That Still Help

Even without the federal residential credit, several states offer their own solar incentives that reduce costs regardless of whether you lease, sign a PPA, or buy.

How to Choose the Right Option

Forget the generic advice. Here is a practical decision framework based on real financial situations homeowners face.

Choose a Lease If:

• You have no savings to put toward solar and your credit score makes a solar loan expensive
• You want guaranteed Day 1 savings with zero risk
• You are comfortable with a long-term agreement on your property
• You plan to negotiate a flat-rate lease (no escalator)

Choose a PPA If:

• You live in a high-utility-rate state (CA, MA, CT, NY, HI)
• Your roof gets excellent sun exposure
• You prefer paying only for electricity actually produced
• PPAs are legal in your state (check — some states restrict them)

Choose a Prepaid Lease If:

• You have $12,000–$18,000 available
• You want the benefits of ownership without the full purchase price
• You plan to stay in your home for at least 6–8 years
• You want no monthly payments and no escalator risk

Choose a Cash Purchase If:

• You have $20,000+ available and no better use for the capital
• You plan to stay in your home for 15+ years
• You live in a state with strong net metering at retail rate
• You value owning the asset outright with no strings attached

5 Mistakes to Avoid When Going Solar in 2026

1. Assuming You Can Still Claim the 25D Tax Credit

We still see solar installers advertising "30% tax credit" without mentioning that it only applies to leases and PPAs where the company claims it — not to homeowner purchases. If a salesperson tells you that you personally will get a 30% federal tax credit on a purchased system in 2026, find a different installer.

2. Ignoring the Escalator Clause

A 2.9% annual escalator on a $130/month lease means you will pay over $58,000 total over 25 years. A flat-rate lease at $150/month totals $45,000. That escalator costs you $13,000. Read the contract carefully and push back on any escalator above 1.5%.

3. Signing Without Comparing Multiple Quotes

Prices vary dramatically between installers. Get at least three quotes. Platforms like EnergySage, Solar.com, and local installer networks make comparison shopping fast and free. The difference between the cheapest and most expensive quote for the same system size can be $4,000 to $8,000.

4. Overlooking Net Metering Changes

Net metering policies are shifting in many states. California's NEM 3.0 drastically reduced the value of solar exports. Some utilities now credit exports at wholesale rates ($0.03–$0.05/kWh) instead of retail ($0.15–$0.25/kWh). This directly affects your payback period. Research your utility's current net metering policy before signing anything.

5. Skipping the Foreign Entity of Concern (FEOC) Question

The OBBBA introduced strict Foreign Entity of Concern restrictions. Solar projects using equipment from prohibited foreign entities can lose their tax credit eligibility. This primarily affects the installer's ability to claim the 48E credit on lease and PPA systems. Ask your installer directly: "Does your equipment comply with FEOC requirements?" If they cannot answer clearly, that is a red flag.

Frequently Asked Questions

Is there any federal tax credit for solar in 2026?

Not for homeowner-owned systems. The Section 25D Residential Clean Energy Credit was terminated by the OBBBA for installations after December 31, 2025. However, the commercial Section 48E credit still applies to business-owned solar, which is why leases and PPAs can still offer savings based on that credit.

What is a prepaid solar lease?

A prepaid lease lets you pay for 20–25 years of solar energy in one upfront payment. The installer retains ownership for at least 6 years to claim the business tax credit, then typically offers you ownership transfer. You pay about 70% of what a cash purchase would cost because the installer's tax credit savings are passed to you.

Can I still buy solar panels with a loan?

Yes. Solar loans are still available from credit unions, banks, and specialized solar lenders. However, without the 25D tax credit to help pay down the principal, your monthly loan payment will be higher than it would have been in 2025. Compare the total cost of a financed purchase against a lease or PPA to see which saves more.

Will the solar tax credit come back?

There is no legislation currently pending to restore the residential solar tax credit. Congress could revisit this in future sessions, but counting on a future credit is not a sound financial strategy. Make your decision based on current incentives.

What happens if I sell my house with a solar lease?

The lease transfers to the new homeowner, assuming they meet the credit requirements and agree to the terms. If the buyer refuses to assume the lease, you may need to buy out the remaining term — which can cost $5,000 to $15,000 depending on how far into the lease you are. Prepaid leases are simpler to transfer since there are no remaining payments.

Do HOMES or HEAR rebates apply to solar panels?

No. The HOMES and HEAR federal rebate programs do not cover solar panel installations. They are limited to energy efficiency improvements like heat pumps, insulation, electrical panel upgrades, and appliances. For solar-specific incentives in 2026, see our state-by-state solar rebate guide.

Is solar worth it in 2026 without the tax credit?

For most homeowners, yes. Residential solar delivers $28,000 to $50,000 in electricity savings over 25 years depending on your option and location. Even without the federal credit, the economics work — you just need to choose the right ownership model for your situation. Prepaid leases and PPAs, in particular, still deliver strong returns because the installer's tax credit lowers your effective cost.

Bottom Line

The end of the residential solar tax credit changed the game, but it did not end it. In 2026, the smartest move for most homeowners is a prepaid solar lease — you get the benefit of the business tax credit passed through to you, pay nothing monthly, and gain ownership after 6 years. If you do not have $14,000+ upfront, a flat-rate lease or PPA still delivers meaningful savings from day one.

Cash purchases remain the highest-return option over 25 years, but the 10+ year payback means they only make sense for long-term homeowners who can absorb the upfront cost comfortably.

Whatever route you choose: get multiple quotes, avoid escalator traps, verify FEOC compliance, and check your state incentives. The savings are still there — you just have to be more strategic about capturing them.
