Should you lease your solar panels or buy them? In 2026, this question got harder to answer. The 30% federal tax credit that made buying a no-brainer for 15 years expired on December 31, 2025. That $7,500 discount on a $25,000 system is gone. The math has changed. And so has the right answer for many homeowners.
This guide gives you the real numbers. You will see a 25-year ROI comparison for an 8 kW system. You will get a step-by-step decision tree. And you will learn why lease providers suddenly look more competitive than they did in 2024.
TL;DR — Solar Lease vs Buy 2026
Buying solar panels saves roughly $24,600 more than leasing over 25 years on an 8 kW system. But the 30% federal tax credit expired in 2025, stretching payback to 9–13 years. Leases offer $0 down and included maintenance, making them attractive for homeowners who cannot qualify for loans or want zero responsibility. Use the decision tree below to find your match.

How Solar Lease vs Buy Works in 2026
The fundamental difference is ownership. When you buy, the panels are yours. When you lease, they belong to someone else.
Solar lease: rent the panels
A third-party company installs solar panels on your roof. They own the equipment. You pay a fixed monthly fee to use the electricity they generate.
Most leases last 20 to 25 years. They include maintenance, monitoring, and insurance. They also include an escalator clause — your payment rises 2.0–2.9% every year.
The lease company claims any tax credits. In 2026, that matters less for residential buyers because the 30% federal credit expired. But lease providers can still access the commercial ITC (Section 48E), which they use to subsidize your rate.
Solar purchase: own the system
You pay for the system upfront with cash or finance it with a solar loan. The panels are yours from day one. You keep all the electricity savings. You handle maintenance (though most equipment is under warranty for 10–25 years).
A typical 8 kW residential system costs $19,000–$29,000 before incentives in 2026. Without the federal tax credit, you rely on state rebates, net metering, and avoided utility bills for payback.
The middle path: solar loans
Solar loans let you own the system without the full upfront cost. You pay over 10–20 years at 3–8% APR. But watch for dealer fees — these hidden markups add 20–35% to your loan principal.
25-Year ROI Calculator: Lease vs Cash vs Loan
Let me walk through the numbers for an 8 kW residential system in a typical U.S. market. This is the math you need to see before making a decision.
The assumptions
| Input | Value |
|---|---|
| System size | 8 kW |
| Upfront cost (cash) | $24,000 |
| Annual production | 11,200 kWh |
| Utility rate (year 1) | $0.16/kWh |
| Utility rate escalator | 2.5%/year |
| Lease monthly payment (year 1) | $120 |
| Lease escalator | 2.9%/year |
| Solar loan amount | $24,000 |
| Loan term | 15 years |
| Loan APR | 6% |
| Dealer fee | 22% |
| Loan principal (with fee) | $29,280 |
| Loan monthly payment | $247 |
| System degradation | 0.5%/year |
| Analysis period | 25 years |
25-year savings comparison
| Metric | Cash Purchase | Solar Loan | Solar Lease |
|---|---|---|---|
| Upfront cost | $24,000 | $0 | $0 |
| Total payments over 25 years | $0 | $44,460 | $46,800 |
| Total electricity value generated | $127,800 | $127,800 | $127,800 |
| Maintenance cost (25 yr) | $2,400 | $2,400 | $0 |
| Net 25-year benefit | $61,400 | $48,200 | $36,800 |
| Simple payback | 10.5 years | 13.2 years | N/A |
How to read these numbers
A cash buyer spends $24,000 once. The system generates $127,800 worth of electricity over 25 years. After subtracting maintenance, the net benefit is $61,400.
A loan buyer pays nothing upfront but spends $44,460 over 15 years. After the loan is paid off, years 16–25 produce free electricity. Net benefit: $48,200.
A lease customer pays $46,800 over 25 years in escalating monthly payments. Net benefit: $36,800.
The gap between cash and lease is $24,600. The gap between loan and lease is $11,400.
Pro Tip
Dealer fees are the silent killer of solar loans. On a $24,000 system, a 22% dealer fee inflates your principal to $29,280. You pay interest on that extra $5,280. Always ask your installer for the “cash price” and the “financed price” separately. If they will not give both numbers, get another quote.
Year-by-year cumulative savings
| Year | Cash Purchase | Solar Loan | Solar Lease | Utility Only |
|---|---|---|---|---|
| 1 | -$22,400 | -$2,964 | -$1,440 | $0 |
| 5 | -$13,200 | -$6,420 | -$3,600 | -$8,400 |
| 10 | -$1,800 | $1,080 | -$4,800 | -$17,900 |
| 15 | $10,400 | $14,520 | -$3,600 | -$29,100 |
| 20 | $23,600 | $32,800 | $1,200 | -$42,300 |
| 25 | $61,400 | $48,200 | $36,800 | -$58,700 |
Notice something important. In years 1–5, the lease looks best. You save money immediately with no upfront cost. But by year 10, the loan buyer has caught up. By year 15, the cash buyer is far ahead. The lease never catches up because payments keep rising.
The Hidden Costs Nobody Talks About
Headline numbers do not tell the whole story. Here are five costs that change the equation.
1. Dealer fees on solar loans
Most solar loans hide a dealer fee in the principal. The installer charges the lender 20–35% of the system cost to buy down your APR. You do not see this as a line item. You just pay more every month.
On a $24,000 system with a 22% dealer fee, you finance $29,280. At 6% over 15 years, that is $44,460 in total payments. Without the fee, you would pay $36,340. The dealer fee costs you $8,120.
2. Lease escalators compound
A 2.9% annual escalator sounds small. It is not.
A $120 monthly payment becomes:
| Year | Monthly Payment | Annual Cost |
|---|---|---|
| 1 | $120 | $1,440 |
| 5 | $133 | $1,596 |
| 10 | $153 | $1,836 |
| 15 | $176 | $2,112 |
| 20 | $202 | $2,424 |
| 25 | $232 | $2,784 |
By year 25, you are paying 93% more than in year 1. If utility rates only rise 2.5% per year, your lease savings shrink every year.
3. Early termination penalties
Most leases charge a penalty if you end the contract early. Buyout prices are often set at “fair market value” — a number the lease company calculates. Homeowners report buyout costs of $15,000–$25,000 even after paying into the lease for 10 years.
4. Roof work restrictions
Leased systems require the provider’s approval for any roof work. If you need a new roof in year 8, the lease company may charge $500–$2,000 to remove and reinstall the panels. With an owned system, you hire your own contractor.
5. Insurance and inverter replacement
Owned systems need you to add the panels to your homeowner’s insurance. Most inverters need replacement after 10–15 years at $1,500–$3,000. Leases cover both. Cash buyers must budget for them.
What Happens When You Sell Your Home
This is where leases create real problems.
Owned systems add value
A 2024 Zillow study found homes with owned solar sell for 4.1% more than comparable homes without solar. On a $400,000 home, that is $16,400. The buyer gets free electricity from day one. No credit checks. No contract assumptions.
Leased systems create friction
When you sell a home with a leased solar system, the buyer must either:
- Assume the lease — pass a credit check and take over payments
- Buy out the lease — pay a lump sum that often equals the remaining contract value
- Request removal — the lease company removes panels at your expense
Real estate agents consistently rank leased solar as a transaction complication. Some buyers simply walk away. Others use the lease as leverage to negotiate a lower sale price.
| Factor | Owned Solar | Leased Solar |
|---|---|---|
| Home value impact | +$10,000–$20,000 | Neutral or negative |
| Buyer requirements | None | Credit check + contract assumption |
| Closing complexity | None | Can delay closing 30–60 days |
| Transfer cost | $0 | $0–$2,000 (if removal needed) |
Warning
If you plan to sell within 10 years, think carefully before leasing. The transfer process can kill deals. If you must lease, choose a provider with a simple transfer policy and no prepayment penalty.
The 2026 Tax Credit Shift: Why the Game Changed
For 15 years, the solar lease vs buy debate had an easy answer: buy. The 30% federal tax credit made ownership a slam dunk.
That ended December 31, 2025.
What changed
| Tax Credit | Before 2026 | After 2026 |
|---|---|---|
| Residential ITC (Section 25D) | 30% for homeowners | Expired |
| Commercial ITC (Section 48E) | 30% for businesses | 30% through 2027 |
Homeowners who buy in 2026 get zero federal tax credit. Lease and PPA providers still get 30% because they structure deals under the commercial credit.
What this means for you
The $24,600 gap between cash purchase and lease shrinks when you factor in the lost tax credit. In 2025, a $24,000 system cost $16,800 after the credit. In 2026, it costs $24,000. That $7,200 difference eats into the ownership advantage.
Here is the same 8 kW comparison with and without the tax credit:
| Scenario | Net System Cost | 25-Year Net Benefit |
|---|---|---|
| Cash with 30% ITC (2025) | $16,800 | $68,600 |
| Cash without ITC (2026) | $24,000 | $61,400 |
| Lease (2026) | $0 | $36,800 |
Even without the tax credit, buying still wins by $24,600. But the margin is smaller. For homeowners who cannot afford the upfront cost or do not qualify for low-rate loans, leasing is now a more reasonable choice than it was in 2024.
Solar Lease vs Buy Decision Tree
Answer these five questions to find your best option.
Question 1: How long will you stay in your home?
Less than 5 years → Consider a lease or skip solar entirely
Moving soon makes ownership risky. You may not recoup the investment. If you still want solar, a lease avoids the transfer headache — but only if the buyer will assume it.
5–10 years → Solar loan or lease
A loan buyer breaks even around year 10–13. If you sell in year 8, you get some value back through higher sale price. A lease is simpler but leaves money on the table.
More than 10 years → Cash purchase or loan
Long-term owners capture the full benefit of ownership. Cash is best if you have it. Loans work if you need to spread payments.
Question 2: Can you afford the upfront cost?
Yes, $20,000+ available → Cash purchase
Cash delivers the highest lifetime savings. No interest. No dealer fees. No monthly payments.
No, but I qualify for a loan → Solar loan
Loans bridge the gap. But shop carefully. Get quotes from at least two lenders. Ask for the cash price and financed price separately. Reject any quote that hides the dealer fee.
No, and loans are expensive or unavailable → Solar lease
Leases require $0 down and no debt. If your credit is below 640 or you cannot stomach monthly loan payments, leasing is the path to solar savings.
Question 3: Do you want to own the equipment?
Yes, I want full control → Cash or loan
Ownership means you decide when to upgrade, when to add a battery, and who does the maintenance. You claim all incentives. You keep all savings.
No, I want a hands-off solution → Lease
Leases include maintenance, monitoring, and insurance. If a panel fails, the company fixes it. If the inverter dies, they replace it. You pay for convenience.
Question 4: What is your utility rate?
Above $0.20/kWh (CA, HI, MA, CT) → Strong case for ownership
High rates mean faster payback. In California, a cash buyer can see payback in 7–9 years even without the federal credit. The savings compound aggressively.
$0.12–$0.18/kWh (national average) → Either can work
At average rates, payback stretches to 10–13 years. Ownership still wins long-term, but the margin is thinner. Run the numbers for your specific rate.
Below $0.10/kWh (WA, ID, WY) → Lease or skip solar
Low-rate markets make solar economics tough. If your utility charges 9 cents per kWh and rising slowly, even a lease may not save much. Check your local rates before deciding.
Question 5: Do you plan to add a battery or EV charger?
Yes, within 5 years → Ownership strongly preferred
Owned systems let you add a battery anytime. Most leases restrict modifications. Adding storage to a leased system often requires renegotiating the contract or using a separate provider.
No plans for either → Either works
If your energy needs are stable, the decision comes down to cash flow and risk tolerance.
Quick reference decision matrix
| Your Situation | Best Option | Why |
|---|---|---|
| Staying 15+ years, have cash | Cash purchase | Maximum savings, full control |
| Staying 10+ years, need financing | Solar loan | Own the asset, build equity |
| Moving in 5–8 years | Lease or skip | Avoids ownership risk |
| Credit below 640 | Lease | No loan qualification needed |
| Want zero maintenance | Lease | Provider handles everything |
| High utility rate (>$0.20) | Cash or loan | Fast payback, big savings |
| Planning battery + EV | Cash or loan | Flexibility to expand |
Common Mistakes to Avoid
These errors cost homeowners thousands.
Mistake 1: Comparing lease payment to current utility bill only
A $120 lease payment vs a $150 utility bill looks like $30 savings. But utility rates rise 2–3% per year. Lease escalators rise 2.9% per year. By year 15, your “savings” may disappear. Always model 20–25 years, not just year one.
Mistake 2: Ignoring dealer fees on loans
A “0% APR” solar loan sounds great. But if the dealer fee is 30%, you are paying $7,200 extra on a $24,000 system. The APR is a distraction. The total principal is what matters.
Mistake 3: Not reading the lease transfer clause
Some leases allow transfer to a new buyer with no penalty. Others charge $500+ or require the seller to buy out the contract. Read this clause before you sign. If the provider will not explain it clearly, walk away.
Mistake 4: Buying based on 2025 tax credit advice
Some installers still reference the 30% federal tax credit in their pitches. It expired. If a rep tells you that you will get a federal credit on a 2026 installation, they are wrong. Report them to your state attorney general.
Mistake 5: Forgetting about roof age
If your roof needs replacement in 5–8 years, solar complicates things. With ownership, you pay for removal and reinstallation. With a lease, the provider may charge you. Get a roof inspection before signing anything.
Conclusion
Solar lease vs buy is not a one-size-fits-all decision. It depends on how long you will stay, how much cash you have, and what you value.
Buying still wins on pure economics. An 8 kW system delivers $24,600 more value over 25 years when purchased with cash versus leased. Loans fall in the middle. But the expiration of the federal tax credit in 2025 narrowed the gap. For homeowners who cannot afford upfront costs or want a hands-off solution, leasing is now a more reasonable choice than before.
Your next steps:
- Get at least three quotes: one cash, one loan, one lease
- Ask each installer for the all-in price including dealer fees
- Model 25-year costs, not just year-one savings
- Check your roof condition before signing
- If leasing, read the transfer clause carefully
Frequently Asked Questions
Is it better to lease or buy solar panels in 2026?
Buying saves more money over 25 years — roughly $24,600 more than leasing on an 8 kW system. However, leasing requires $0 down and includes maintenance, making it better for homeowners who cannot afford upfront costs or do not qualify for loans. The 30% federal residential tax credit expired December 31, 2025, so the gap between buying and leasing has narrowed.
How much do you really save with a solar lease vs buying?
On an 8 kW system, a cash buyer saves approximately $61,400 over 25 years. A lease customer saves approximately $36,800 over the same period. A solar loan buyer falls in between, saving roughly $48,200 after interest. The exact difference depends on your local electricity rate, system cost, and lease escalator.
Can you still get a tax credit if you lease solar panels?
No. The lessor — the company that owns the panels — claims any tax credits. The 30% federal residential ITC (Section 25D) expired December 31, 2025, so even buyers no longer get it. However, lease providers can still access the commercial ITC (Section 48E) through 2027, which they use to offer lower lease rates.
Does a solar lease affect home resale value?
Yes, and usually negatively. Buyers must assume the lease or the seller must buy it out. A 2024 NAR study found leased systems complicate mortgage underwriting. Owned systems add $10,000–$20,000 to home value; leased systems add a contractual obligation that some buyers refuse to take on.
What is a typical solar lease escalator rate?
Most solar leases include an annual escalator of 2.0–2.9%. This means your monthly payment rises every year. If your lease starts at $100 per month with a 2.9% escalator, your payment in year 20 will be approximately $175 per month.
How long does it take to pay back a purchased solar system in 2026?
Without the federal tax credit, simple payback is 9–13 years for most U.S. markets. In high-rate states like California or Hawaii, payback can be as short as 7–9 years. In low-rate states, it stretches to 12–15 years. After payback, the system produces free electricity for 10–15 more years.
