Solar Lease vs Buy vs PPA: Which One Is Actually Better

There are three ways to get solar panels on your roof: buy them outright, lease them, or sign a Power Purchase Agreement (PPA). The solar industry loves to make this confusing, because confusion makes you easier to sell to. Here is the straightforward version. If you are still figuring out whether solar is worth it at all, start with our is solar worth it in 2026 guide.

Each option has a clear best-fit scenario. The trick is figuring out which one matches your financial situation, your plans for the home, and how much you care about maximizing long-term savings versus minimizing upfront hassle.

Option 1: Buying Solar (Cash or Loan)

When you buy a solar system, you own it. You pay the full cost — either in cash or through a solar loan — and every kilowatt-hour those panels produce is yours.

Important 2026 update: The federal 30% ITC (Section 25D) expired for homeowner-purchased systems on December 31, 2025. Purchased solar systems receive no federal credit in 2026. Check your state for applicable state-level incentives.

Typical costs for an 8kW system in 2026:

• Cash purchase: $22,000–$28,000 (no federal credit; state incentives may reduce by $2,000–$5,000)
• Solar loan (10–20 year term, 5–7% APR): $28,000–$38,000 total with interest

Pros:

• Highest total savings over the life of the system (25–30 years)
• You own the equipment and all the electricity it produces
• Increases your home value by an average of $15,000–$20,000
• No escalator clauses or annual rate increases
• Eligible for state tax credits and incentive programs

Cons:

• Significant upfront cost (cash) or long-term debt (loan)
• You are responsible for maintenance and repairs after the warranty period
• If you finance, monthly loan payments may exceed electricity savings in early years

25-year cost comparison (8kW system, $0.16/kWh average rate, 3% annual rate increase):

• Total investment: $24,000 (cash)
• Total electricity savings: ~$58,000
• Net benefit: ~$34,000 profit

Buying is the clear winner on pure economics. If you have the cash or can get a loan at a reasonable rate and plan to stay in the home for 10+ years, purchasing delivers the best return.

Option 2: Solar Lease

With a solar lease, a company installs panels on your roof and you pay a fixed monthly fee to use the electricity they produce. You do not own the panels. The leasing company does.

Typical terms:

• Monthly payment: $80–$180/month
• Contract length: 20–25 years
• Annual escalator: 1–3% per year (your payment goes up annually)
• Upfront cost: $0

Pros:

• Zero upfront cost
• Maintenance and repairs are the leasing company's responsibility
• Predictable monthly payment
• Immediate electricity bill reduction (usually 10–30%)

Cons:

• You do not own the system or the energy it produces
• Total cost over 25 years often exceeds the cost of buying
• Annual escalators mean your payment in year 20 is significantly higher than year 1
• Complicates selling your home — the buyer must qualify for and assume the lease, or you must buy out the remaining term
• You do not get state incentives or tax credits (the leasing company does) — however, the leasing company can claim the Section 48E commercial ITC through 2027 and may pass some savings through to you via lower rates
• Early termination fees can be steep ($5,000–$20,000+)

25-year cost comparison (same 8kW system):

• Monthly payment starting at $130, with 2.5% annual escalator
• Total payments over 25 years: ~$52,000
• Total electricity savings: ~$58,000
• Net benefit: ~$6,000

The savings are real but modest. And that 2.5% escalator is doing heavy lifting — by year 20, your lease payment is about $195/month, which may be close to what you would have paid the utility anyway.

Option 3: Power Purchase Agreement (PPA)

A PPA is similar to a lease, but instead of a fixed monthly fee, you pay per kilowatt-hour of electricity the panels produce. The rate is typically lower than your utility rate — that is where the savings come from.

Typical terms:

• Per-kWh rate: $0.10–$0.14/kWh (compared to utility rates of $0.14–$0.35/kWh)
• Contract length: 20–25 years
• Annual escalator: 1–3% per year
• Upfront cost: $0

Pros:

• Zero upfront cost
• You only pay for electricity actually produced
• Maintenance is the PPA provider's responsibility
• Savings scale with your usage

Cons:

• Same ownership issues as a lease — you do not own the panels
• Same home sale complications
• Annual escalators mean the rate advantage shrinks over time
• Not available in all states (some states restrict PPAs)
• The PPA company claims the tax credits and incentive revenue — including the Section 48E commercial ITC through 2027, which purchased homeowners can no longer claim

25-year cost comparison:

• Starting rate: $0.12/kWh with 2.5% escalator
• Total payments over 25 years: ~$42,000
• Total electricity savings vs. utility: ~$16,000
• Net benefit: ~$16,000

PPAs generally come out slightly ahead of leases because you only pay for what the panels produce, and production drops slightly over time (panels degrade about 0.5% per year).

The 25-Year Side-by-Side

| | Cash Purchase | Solar Loan (6%) | Lease | PPA |

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

| Upfront cost | $24,000 | $0 | $0 | $0 |

| Total paid over 25 years | $24,000 | $34,000 | $52,000 | $42,000 |

| Total electricity savings | $58,000 | $58,000 | $58,000 | $58,000 |

| Net savings | $34,000 | $24,000 | $6,000 | $16,000 |

| You own the system | Yes | Yes | No | No |

| Home value increase | Yes | Yes | No | No |

| Maintenance responsibility | You | You | Company | Company |

The numbers speak clearly. Ownership — whether cash or financed — delivers meaningfully better long-term economics. Leases and PPAs are not bad deals, but they transfer most of the financial upside to the solar company.

Who Should Pick What

Buy with cash if: You have the savings, you plan to stay in the home 10+ years, and you want the absolute best financial return. This is the optimal choice for most homeowners who can afford it.

Buy with a loan if: You do not have $20,000+ in cash but have good credit (680+) and want to own the system. Make sure the monthly loan payment is less than your current electricity bill — that way you save from day one.

Lease if: You want zero upfront cost, do not want to deal with maintenance, and are comfortable with modest savings. Be very careful with the escalator clause — 3% compounding over 25 years nearly doubles your payment.

PPA if: Similar to a lease, but available in your state and you prefer paying only for what the panels produce. Slightly better economics than a lease in most cases.

The One Thing Most Articles Leave Out

If you lease or sign a PPA and want to sell your home, the new buyer must either assume your agreement or you have to buy out the remaining contract. This has killed real estate deals. Multiple agents report that leased solar systems add friction to closings and sometimes reduce offers.

Owned solar, on the other hand, is treated like any other home improvement. Studies from Lawrence Berkeley National Laboratory consistently show that owned solar increases resale value.

Key Takeaways

• Buying solar delivers 2–5x more savings over 25 years than leasing or PPAs
• Leases and PPAs have zero upfront cost but you do not own the system and savings are modest
• Watch the annual escalator — a 2.5% escalator on a $130/month lease payment means you are paying $195/month by year 20
• Leases and PPAs complicate home sales — this is a bigger deal than most solar companies admit
• If you cannot buy outright, a solar loan with no dealer fees and a rate under 6% is usually the best middle ground
• Get quotes for all options and compare them side by side — the right answer depends on your specific situation. Our solar quote comparison guide shows you exactly what to look for
