☀️ Buy vs Lease Solar Panels: Which Is Better?
📊 Side-by-Side Comparison
| Aspect | Buy Solar Panels | Lease / PPA |
|---|---|---|
| Upfront Cost | High (cash) or financed with a solar loan. | Little to none. |
| 30% Federal Tax Credit | You claim it (big savings). | The leasing company keeps it. |
| Long-Term Savings | Highest — you own all the production. | Lower — you pay the provider for power. |
| Maintenance | Your responsibility (panels are low-maintenance). | Handled by the provider. |
| Home Value | Adds value; owned system transfers cleanly. | Can complicate or delay a home sale. |
| Best For | Owners who can finance and use the tax credit. | Those wanting zero upfront cost and no upkeep. |
| Bottom Line | More savings and value if you can fund it. | Easy entry, but less benefit overall. |
What is Buy Solar Panels?
Buying solar means you own the system outright — paid in cash or through a solar loan. Ownership unlocks the biggest financial benefits: you claim the 30% federal Investment Tax Credit (plus any state/local incentives), you keep 100% of the energy savings, and the system adds value to your home that transfers cleanly to a buyer. Panels are low-maintenance, and after payback (commonly 7-12 years) the electricity is essentially free.
The trade-off is upfront cost. A typical residential system runs $15,000-$25,000 before incentives. A solar loan spreads that out, often with payments lower than your old electric bill, while you still claim the tax credit. Buying is the clear winner for homeowners who have tax liability to offset and can finance the purchase — it maximizes both savings and home value.

What is Lease / PPA?
Leasing solar — or signing a Power Purchase Agreement (PPA) — lets you go solar with little or no money down. The solar company owns the panels on your roof; you either pay a fixed monthly lease or buy the power they produce at a set per-kWh rate, usually below the utility's. The provider handles installation, maintenance and repairs, so it's a hands-off way to lower your electric bill immediately.
The downsides are significant. Because the company owns the system, it — not you — claims the lucrative 30% tax credit, so your total savings are much smaller. Lease escalator clauses can raise payments over time, and a leased system can complicate selling your home, since the buyer must assume the lease or you must buy it out. Leasing makes sense mainly for owners who can't use the tax credit or won't finance a purchase, prioritizing simplicity over maximum savings.

🔑 Key Differences
- Tax credit: Buyers claim the 30% federal credit; lessees don't.
- Upfront cost: Buying needs cash/financing; leasing is $0-down.
- Savings: Ownership keeps all production value; leasing shares it with the provider.
- Maintenance: Lease provider handles it; owners are responsible (but it's minimal).
- Home sale: Owned systems transfer cleanly; leases can complicate a sale.
- Escalators: Some leases raise payments yearly.
- Decision driver: Whether you can use the tax credit and finance the system.
When to Use Buy Solar Panels
- You have tax liability to offset with the 30% credit.
- You can pay cash or qualify for a solar loan.
- You plan to stay in the home long enough to reach payback.
- You want to maximize savings and home value.
When to Use Lease / PPA
- You can't use the federal tax credit (low/no tax liability).
- You want zero upfront cost and no maintenance responsibility.
- You prefer a hands-off, predictable monthly arrangement.
- You don't want to finance a purchase.

💡 Real-World Examples
Example 1: $20,000 System, Buy with Tax Credit
A $20,000 system qualifies for a $6,000 federal credit, cutting net cost to $14,000. Saving $1,800/year on electricity, payback is under 8 years — then decades of nearly free power. Buying maximizes the return.
Example 2: Same System, Leased
With a lease, $0 down and maybe $1,200/year in savings, but the provider keeps the $6,000 credit and may raise payments 2-3%/year. Easier to start, but lifetime savings are a fraction of owning.
Example 3: Retiree With Low Tax Liability
A retiree who can't fully use the 30% credit may find leasing more practical — they still cut their bill without needing tax liability or upfront cash, trading maximum savings for simplicity.
❓ Frequently Asked Questions
Is it better to buy or lease solar panels?
Buying almost always saves more and lets you claim the 30% federal tax credit, but needs upfront money or a loan. Leasing is $0-down and hands-off but gives the credit and most savings to the provider.
Who gets the solar tax credit on a lease?
The leasing company or PPA provider that owns the system claims the 30% credit — not you. That's a major reason buying saves more.
Does leasing solar hurt my home sale?
It can. Buyers must agree to assume the lease or you must buy it out before selling, which can delay or complicate the transaction. Owned systems transfer cleanly and add value.
How long until solar pays for itself if I buy?
Commonly 7-12 years depending on system cost, incentives, electricity rates and sun exposure. Use our [solar payback calculator](/calculators/solar-payback-calculator.html) to estimate yours.
What is a solar PPA?
A Power Purchase Agreement: the provider owns the panels and you buy the electricity they generate at a set rate, usually below the utility's — similar to a lease but priced per kWh.
