Solar Lease vs Buy vs PPA in 2026: Which Is Right for You?

The solar financing landscape shifted dramatically on January 1, 2026. The residential Investment Tax Credit (ITC) under Section 25D — the 30% federal tax credit that homeowners could claim when purchasing solar panels — expired on December 31, 2025. That single change rewrote the math on every financing option available to you.

If you're comparing a solar lease vs buying outright vs signing a PPA in 2026, the calculus is fundamentally different from what it was even a year ago. This guide breaks down exactly how each option works now, what it costs, and which one makes sense for your situation.

The Big Picture: How the ITC Expiration Changes Everything

For over a decade, the Section 25D residential solar tax credit gave homeowners a dollar-for-dollar reduction on their federal tax bill — 30% of the total installed cost. On a $30,000 system, that was $9,000 back in your pocket. It made buying solar panels the clear financial winner for anyone who could afford the upfront investment or qualify for a loan.

That credit is gone for residential buyers as of 2026.

Here's what most people miss: the commercial ITC (Section 48E) is still alive through at least 2027. Solar companies that own the panels on your roof — through a lease or PPA — can still claim that 30% credit. And they pass a portion of those savings on to you in the form of lower monthly payments or per-kilowatt-hour rates.

This is exactly why industry analysts project that 69% of residential solar installations in 2026 will be third-party owned (TPO) — leases and PPAs. The economics have flipped.

But that doesn't mean buying is dead. Cash purchases still deliver the highest lifetime savings for homeowners who can stomach the upfront cost and the longer payback period. The right answer depends entirely on your financial situation, how long you plan to stay in your home, and what matters most to you.

Solar Financing Options Compared: 2026 At-a-Glance

Buying Solar Panels with Cash in 2026

How a Cash Purchase Works

You pay the full installed cost of the system upfront — typically $25,000 to $35,000 for a 6–10 kW residential system after all costs. You own the panels, the inverter, the racking, and all the electricity they produce for the next 25 to 30 years.

The Math Without the Tax Credit

Here's where 2026 hits hard. In 2025, a $30,000 system effectively cost $21,000 after the 30% ITC. In 2026, that same system costs $30,000. Period.

Example: 8 kW system in a moderate-sun state

• System cost: $30,000
• Annual electricity savings: $2,800 (at $0.16/kWh utility rate)
• Simple payback period: 10.7 years
• 25-year net savings: $40,000+ (accounting for rising utility rates at 3% annual escalation)

Compare that to 2025, when the same system had a payback period of about 7.5 years. The gap is real, but the long-term math still favors ownership — if you have the capital and the patience.

Pros of Buying Solar with Cash

• Highest lifetime savings. No interest, no monthly payments, no company taking a cut. Every kilowatt-hour your panels produce saves you the full retail rate.
• Full ownership and equity. The system is yours. It adds value to your home. You control it completely.
• No escalator clauses. Unlike some leases that increase payments 1–3% per year, your solar electricity is locked in at $0/kWh once the system is paid for.
• Eligible for all local incentives. SRECs, net metering credits, and state-level rebates still go directly to you.

Cons of Buying Solar with Cash

• Large upfront capital required. $25,000–$35,000 is a significant investment that could be deployed elsewhere.
• No federal tax credit. The 25D residential ITC is gone. This was the single biggest financial incentive for buyers.
• Longer payback period. Without the credit, you're looking at 8–12 years instead of 5–8.
• Maintenance is on you. Inverter replacements ($1,500–$3,000 around year 12–15), potential panel issues, and monitoring are your responsibility.
• Opportunity cost. That $30,000 invested in the S&P 500 at historical average returns could generate meaningful returns over the same period.

Solar Loans in 2026: Ownership Without the Upfront Cost

How Solar Loans Work

You finance the full system cost through a solar-specific loan, typically at terms of 10 to 25 years. You own the system from day one. Monthly payments replace (or reduce) your electric bill.

The 2026 Loan Challenge

In previous years, the solar loan playbook was simple: finance the system, then use the 30% tax credit as a lump-sum payment toward the principal in year one. That dropped your effective loan balance by nearly a third immediately. Some lenders even structured loans around this expected credit, offering a lower payment for the first 18 months before a "re-amortization."

That structure no longer works. Without the tax credit windfall, you're financing the full amount for the full term. This means:

• Higher monthly payments than in previous years
• More total interest paid over the life of the loan
• Tighter debt-to-income considerations

Current Solar Loan Rates and Terms (Q1 2026)

When Solar Loans Still Make Sense

Solar loans remain viable when your monthly loan payment is meaningfully less than your current electric bill. If you're paying $300/month for electricity and a 15-year loan costs you $260/month, you're saving $40/month from day one while building equity in a system that will produce free electricity for another 10–15 years after the loan is paid off.

The key metric: compare your total cost of electricity over 25 years with and without solar, not just the monthly payment.

Pros of Solar Loans

• $0 down with full ownership. You own the system and all the electricity it produces.
• Build home equity. An owned solar system adds $15,000–$20,000 to your home value.
• Potential for net savings from month one if your loan payment is less than your electric bill.
• All incentives go to you. SRECs, net metering, and state rebates are yours.

Cons of Solar Loans

• No tax credit to reduce principal. You're financing the full cost.
• Interest adds up. On a 20-year loan, you could pay $22,000+ in interest alone.
• Monthly payments may exceed current electric bill in some cases, especially on shorter loan terms.
• Maintenance responsibility. You own it, you maintain it.
• Credit requirements. Most solar loans require a FICO score of 650+, with the best rates reserved for 720+.

Solar Lease Explained: How It Works in 2026

How a Solar Lease Works

A solar company installs panels on your roof and you pay a fixed monthly fee to use the electricity they produce. The company owns the panels, maintains them, monitors them, and insures them. You get cheaper electricity. They get a reliable revenue stream plus the federal commercial tax credit.

Think of it like renting an apartment vs buying a house. You don't build equity, but you also don't deal with the roof, the furnace, or the plumbing.

Why Leases Are More Attractive in 2026

Here's the critical shift: because the solar company can still claim the 30% commercial ITC under Section 48E, they can offer you lower monthly payments than they otherwise could. You're indirectly benefiting from a tax credit that you can no longer claim yourself.

The gap between buying and leasing has narrowed. In 2025, buying was roughly $15,000–$30,000 cheaper over 25 years. In 2026, that gap has shrunk to $10,000–$20,000 depending on your market and utility rates — still meaningful, but smaller.

Typical Solar Lease Terms in 2026

• Monthly payment: $80–$180 depending on system size and location
• Escalator clause: 0%–3% annual increase (watch this number carefully)
• Contract length: 20–25 years
• Buyout option: Available at fair market value after year 5–7
• Maintenance: Included — panels, inverter, monitoring, repairs
• Insurance: Typically covered by the leasing company

The Escalator Trap

Many solar leases include an annual payment escalator of 1%–3%. This means your $120/month payment in year one becomes $160–$195 by year 15 and $195–$290 by year 25.

Run the numbers on the full contract term, not just the first year. If your lease has a 2.9% escalator and utility rates only rise 2% per year, the lease could eventually cost you more than grid electricity. Always negotiate for the lowest possible escalator — ideally 0%.

Pros of Solar Leases

• $0 down, immediate savings. Start saving on electricity from month one with no upfront investment.
• Maintenance-free. The company handles everything — monitoring, repairs, inverter replacement.
• Predictable costs. Fixed monthly payment (or near-fixed with a low escalator) makes budgeting easy.
• Lower barrier to entry. No large capital outlay, less stringent credit requirements than loans.
• Indirect tax credit benefit. The company's 48E credit keeps your payments lower than they'd otherwise be.

Cons of Solar Leases

• No ownership. You're renting your power plant. No equity, no asset.
• Lower lifetime savings. You'll save $10,000–$25,000 less over 25 years compared to a cash purchase.
• Escalator risk. Annual payment increases can erode savings over time.
• Home sale complications. The buyer must assume the lease or you must buy out the contract. This can slow or complicate sales (more on this below).
• Less flexibility. You can't modify the system, switch providers, or remove panels without the company's approval.
• Long contract. 20–25 years is a serious commitment.

Solar PPA Explained: Pay Only for What You Produce

How a Solar PPA Works

A Power Purchase Agreement (PPA) is structurally similar to a lease, but instead of a fixed monthly payment, you pay for the electricity the system actually produces — measured in kilowatt-hours (kWh). The solar company owns and maintains the system. You buy the power at a rate that's lower than your utility's retail rate.

PPA vs Lease: What's the Difference?

The practical difference is risk allocation. With a lease, you pay the same amount whether it's sunny or cloudy. With a PPA, you only pay for what the panels actually generate. In a particularly cloudy quarter, your PPA bill drops. In a sunny quarter, it's higher — but still below what you'd pay the utility.

Typical PPA Terms in 2026

• Rate: $0.08–$0.14 per kWh (vs. national average utility rate of ~$0.18/kWh)
• Escalator: 0%–2.5% annually
• Contract length: 20–25 years
• Maintenance: Included
• Buyout option: Typically available after year 5–7

When PPAs Beat Leases

PPAs tend to outperform leases in states with high electricity rates, strong net metering, and variable sunshine. If you live in a state where utility rates are $0.20+/kWh and a PPA offers $0.12/kWh, you're saving 40% from day one — and your savings grow as utility rates continue to climb.

PPAs also make more sense if you're concerned about overpaying during low-production months. You're paying for actual value received, not a fixed amount regardless of output.

Pros of Solar PPAs

• $0 down, immediate savings. Lower per-kWh rate than your utility from day one.
• Pay only for what you use. If production drops, your bill drops.
• Maintenance included. Same as a lease — the company handles everything.
• Built-in hedge against utility rate increases. Your PPA rate rises slowly (if at all) while utility rates historically climb 3–5% per year.
• Indirect tax credit benefit. Like leases, the company's 48E credit keeps your rate competitive.

Cons of Solar PPAs

• No ownership. Same as a lease — no equity, no asset.
• Variable monthly costs. Less predictable than a fixed lease payment.
• Escalator risk. Same concern as leases — a high escalator can erode savings.
• Home sale complications. Same transfer requirements as a lease.
• Not available everywhere. PPAs are not legal in all states. Some states restrict or prohibit third-party electricity sales.

Energy Service Agreements: The Newer Option

What Is an ESA?

An Energy Service Agreement (ESA) is a newer financing model that's gaining traction in 2026. Like a PPA, you pay for the energy your system produces. But ESAs often bundle additional services — battery storage, EV charger integration, home energy management — into a single agreement.

The key distinction: ESAs focus on total energy outcomes rather than just solar panel output. Some ESA providers guarantee a certain level of energy savings or production, taking on the performance risk themselves.

How ESAs Differ from PPAs and Leases

Should You Consider an ESA?

ESAs are worth exploring if you want a comprehensive energy solution — solar plus battery storage, for example — without the complexity of separate contracts for each component. They're especially relevant in states with time-of-use rates where battery storage can significantly increase savings.

However, ESAs are still relatively new. The market is less mature, contract terms are less standardized, and it can be harder to compare offers across providers. Read the fine print carefully and consult an independent energy advisor if possible.

Which Solar Option Is Best for You? A Decision Guide

There is no universally "best" option. The right choice depends on your specific financial situation, your plans for the home, and what you value most. Use this decision framework to narrow your options.

Decision Tree: Finding Your Best Solar Financing Option

Step 1: How long do you plan to stay in your home?

• Less than 7 years → A lease or PPA is likely your best bet. The payback period on a purchase is too long to recoup your investment, and transferring a lease/PPA to a buyer is simpler than factoring an owned system into your sale price.
• 7–15 years → All options are viable. Run the numbers for your specific situation.
• 15+ years → A cash purchase or loan delivers the highest long-term returns. You'll be deep into the "free electricity" years where owned systems really shine.

Step 2: Do you have $25,000–$35,000 available?

• Yes, and you don't need it for other investments → Cash purchase offers the highest lifetime savings, even without the tax credit.
• Yes, but you'd rather keep it invested → Compare the expected return on your alternative investment vs. the effective return on a solar purchase (typically 6–10% IRR in 2026). A solar loan or TPO option may make more sense.
• No → Consider a loan (if you want ownership) or a lease/PPA (if you want simplicity).

Step 3: What's your credit score?

• 720+ → You'll qualify for the best solar loan rates. Both ownership and TPO options are open.
• 650–719 → Solar loans are available but at higher rates. Leases and PPAs may offer better effective rates.
• Below 650 → Leases and PPAs are your most accessible options. Some providers approve with scores as low as 580.

Step 4: How important is ownership to you?

• Very important → Cash purchase or loan. You want the asset, the equity, and total control.
• Somewhat important → A loan or a lease with a buyout option. You can transition to ownership later.
• Not important → A lease or PPA delivers savings with zero hassle. You don't care about owning the hardware — you just want cheaper electricity.

Step 5: How do you feel about maintenance?

• Comfortable handling it → Ownership options work. Budget $200–$500/year for maintenance reserves.
• Want zero maintenance responsibility → Lease, PPA, or ESA. The company handles everything.

Quick Reference: Best Option by Situation

How Solar Financing Affects Your Home Value

This is one of the most significant — and most overlooked — differences between buying and leasing solar panels.

Owned Systems Add Real Value

Multiple studies, including research by Lawrence Berkeley National Laboratory, have consistently found that owned solar systems increase home sale prices. The current data suggests:

• Owned solar adds approximately $15,000–$20,000 to the sale price of a median-value home.
• Buyers perceive owned solar as a permanent upgrade, similar to a new roof or kitchen renovation.
• Homes with owned solar sell faster than comparable homes without solar in most markets.

This value boost applies whether you paid cash or financed with a loan — as long as the loan is paid off or transferable at closing. If you still owe on a solar loan, that balance typically comes out of your sale proceeds, but the increased home value more than compensates in most cases.

Leased/PPA Systems Can Complicate Sales

Third-party owned systems present a different picture:

• The buyer must qualify to assume the lease or PPA. If they can't or won't, you may need to buy out the remaining contract — which can cost $5,000–$15,000+ depending on the term remaining.
• Some buyers are deterred by the obligation of assuming a 15–20 year contract they didn't choose.
• Appraisers generally don't add value for leased systems since they're not an owned asset.
• Real estate agents report that leased solar can add 1–3 weeks to the closing timeline due to the transfer process.

This doesn't mean leased systems kill home sales. Millions of homes have been sold with leased solar systems, and in markets where electricity is expensive, buyers may actually welcome the existing lease. But it's a factor to weigh, especially if you think you might sell within the contract term.

The Home Value Calculation

State-Specific Factors That Change the Math

Solar financing isn't one-size-fits-all across the country. Several state-level policies dramatically affect which option delivers the best value.

Net Metering Policies

Net metering — the policy that credits you for excess solar electricity sent back to the grid — is the single biggest variable in your solar savings calculation.

• Full retail net metering (you get credited at the full retail rate): Cash purchase and loans benefit the most. States like New Jersey, Massachusetts, and Maryland still offer strong net metering that maximizes ownership returns.
• Reduced or avoided-cost net metering (you get credited at a wholesale rate): The value of excess production drops significantly. This narrows the gap between ownership and TPO options. California's NEM 3.0 is the most prominent example.
• No net metering: Battery storage becomes essential to maximize self-consumption. ESAs that bundle storage may be the smartest play.

State Incentives and Rebates

Some states still offer their own solar tax credits, rebates, or performance-based incentives that go directly to the system owner:

• State tax credits (e.g., South Carolina's 25% credit, New York's 25% credit up to $5,000): These go to the system owner. If you lease, the solar company gets these — not you.
• SRECs (Solar Renewable Energy Certificates): In SREC markets like New Jersey, Massachusetts, and Pennsylvania, owned systems can generate $500–$2,000+ annually in additional income. This significantly improves the payback on a cash purchase.
• Utility rebates: Some utilities offer upfront rebates that reduce the installed cost. These typically go to the system owner.

States Where PPAs Aren't Available

PPAs involve selling electricity from a third party, which some states' utility regulations prohibit or restrict. As of early 2026, PPAs face restrictions in states including:

• Kentucky
• Oklahoma
• Indiana
• Florida (limited)
• Several others with partial restrictions

If you live in one of these states, your TPO options may be limited to leases. Check your state's current regulations before assuming a PPA is available.

High-Rate States Where TPO Shines

In states with high utility rates — California, Connecticut, Massachusetts, New York, Rhode Island, Hawaii — even a lease or PPA can deliver enormous savings because the baseline cost of electricity is so high. A PPA at $0.12/kWh in a state where the utility charges $0.25/kWh is a 52% discount from day one.

FAQ: People Also Ask

Is it better to buy or lease solar panels in 2026?

It depends on your financial situation and time horizon. Cash purchases still deliver the highest lifetime savings — typically $15,000–$30,000 more than a lease over 25 years. However, without the federal residential tax credit, the upfront cost is higher and the payback period is longer (8–12 years). If you don't have the upfront capital, plan to move within 7 years, or want zero maintenance responsibility, a lease or PPA may be the better choice. The gap between buying and leasing has narrowed significantly in 2026 because solar companies can still claim the 30% commercial ITC and pass savings to you through lower payments.

What happened to the solar tax credit in 2026?

The residential solar Investment Tax Credit (Section 25D) expired on December 31, 2025. Homeowners who purchase solar panels in 2026 or later cannot claim any federal tax credit on their personal returns. However, the commercial ITC (Section 48E) remains at 30% through at least 2027. Solar companies that own systems through leases and PPAs can still claim this credit, which is why third-party ownership has become more financially competitive in 2026.

Can I still get solar with no money down?

Yes. Solar leases, PPAs, and most solar loans offer $0-down options. With a lease or PPA, there is never an upfront cost — you simply start paying a monthly fee (lease) or per-kWh rate (PPA) that's lower than your current electric bill. Solar loans also typically require $0 down, though you'll need to qualify based on your credit score and debt-to-income ratio.

What is a solar PPA and how does it differ from a lease?

A Solar Power Purchase Agreement (PPA) is a contract where you buy the electricity your rooftop solar system produces at a set per-kWh rate, rather than paying a fixed monthly fee. With a lease, you pay the same amount every month regardless of how much electricity the panels produce. With a PPA, your payment fluctuates with actual production — you pay less in cloudy months and more in sunny months, but always at a rate below your utility's retail price. Both options involve $0 down, no ownership, and included maintenance.

What happens to my solar lease if I sell my house?

When you sell a home with a leased solar system, you generally have three options: (1) transfer the lease to the new buyer, who must qualify with the solar company; (2) buy out the remaining lease yourself before the sale; or (3) in some cases, have the solar company remove the system. Most sellers choose to transfer the lease. This requires the buyer to agree to assume the remaining contract, which can occasionally slow the sale or deter buyers who don't want a long-term obligation. Industry data suggests homes with leased solar take slightly longer to sell but still sell at comparable prices.

Are solar loans worth it without the tax credit?

Solar loans can still be worth it in 2026, but the math is tighter. Without the 30% tax credit to knock down the principal in year one, you're financing the full system cost and paying more interest over the life of the loan. The key test: if your monthly loan payment is less than your current electric bill, you're saving money from day one while building equity in an energy-producing asset. On a 15-year loan at 6.5% for a $30,000 system, your monthly payment would be around $260. If your electric bill is currently $300+, the loan still pencils out — especially since the system will produce free electricity for another 10–15 years after the loan is paid off.

What is the payback period for solar panels in 2026?

Without the federal residential tax credit, the typical payback period for a cash solar purchase in 2026 is 8–12 years, depending on your local electricity rates, system size, sun exposure, and available state/local incentives. In high-rate states like California, Massachusetts, or Connecticut, payback can be as fast as 7–8 years. In lower-rate states, it may stretch to 12–14 years. With a solar loan, the effective payback (when cumulative savings exceed cumulative payments) is typically 10–15 years.

What is an Energy Service Agreement (ESA)?

An ESA is a newer solar financing model similar to a PPA, but typically broader in scope. Instead of just covering solar panels, an ESA may bundle solar, battery storage, EV charging, and energy management into a single agreement. You pay for the energy outcomes — often with a performance guarantee — rather than owning the equipment. ESAs are gaining traction in 2026 as homeowners look for comprehensive energy solutions, but the market is still maturing and contracts can be more complex than traditional leases or PPAs.

Do solar panels increase home value in 2026?

Owned solar systems increase home value by approximately $15,000–$20,000 on average, according to studies by Lawrence Berkeley National Laboratory and the Appraisal Institute. This premium applies whether you paid cash or financed with a loan. Leased systems generally do not increase home value and can complicate the sale because the buyer must agree to assume the lease. The home value boost is one of the strongest financial arguments for purchasing rather than leasing, especially for homeowners who plan to sell within the system's lifetime.

The Bottom Line

The 2026 solar financing landscape is defined by one seismic shift: the residential tax credit is gone, but the commercial tax credit lives on. That single fact has reshaped the economics of every option.

If you have the capital and a long time horizon, a cash purchase remains the king of lifetime savings. You'll wait longer for payback than you would have in 2025, but over 25 years, you'll save $25,000–$50,000 while adding real value to your home. No other option matches that return.

If you want ownership without the lump sum, a solar loan still works — but scrutinize the interest rate and term length. The total cost of a 20+ year loan can significantly eat into your savings. Shorter loan terms with manageable payments are the sweet spot.

If you want simplicity, zero upfront cost, and zero maintenance, a lease or PPA has never been more competitive. With solar companies passing 48E tax credit savings to you through lower rates, the effective cost gap between buying and leasing is the narrowest it's ever been. Just watch out for high escalator clauses and understand the home sale implications.

If you want a comprehensive energy solution, an ESA that bundles solar with battery storage may be worth exploring — but do your due diligence on the provider and contract terms.

There's no wrong answer here — only the answer that fits your life. Run the numbers for your specific situation, get multiple quotes, and don't let anyone push you toward one option without showing you the 25-year math.
