If you have met with a solar sales representative, they have likely presented you with multiple options for getting solar panels on your roof: buying with cash, financing with a solar loan, or leasing the system through a Power Purchase Agreement (PPA) or solar lease.
While they may pitch leasing as "free solar panels," the reality is that how you pay for solar determines your long-term savings and home equity. Here is a comparison of buying vs. leasing in 2026.
1. Buying Solar Panels (Cash or Loan)
When you purchase a solar system, you own the equipment from day one (or after your loan is paid off).
Pros:
- Maximum Lifetime Savings: Because you don't pay ongoing lease fees, buying yields the highest return on investment. You keep 100% of the utility savings.
- You Keep the 30% Federal Tax Credit: The homeowner gets the federal Residential Clean Energy Credit (worth $6,000+ on average).
- Adds Home Resale Value: Studies show owned solar panels increase home values by roughly 4%. Buyers appreciate a home with no electric bill and no monthly lease transfer hassles.
Cons:
- High Upfront Cost (Cash): Requires an initial outlay of $15,000 to $25,000.
- Maintenance Responsibility: While panels have 25-year warranties, you are responsible for coordination and labor costs if components break.
2. Leasing Solar Panels / Power Purchase Agreements (PPAs)
With a solar lease or PPA, a third-party solar company owns the panels on your roof. You either pay a fixed monthly rent (solar lease) or buy the electricity generated by the panels at a locked-in rate per kWh (PPA).
Pros:
- $0 Upfront Cost: The leasing company covers all installation and equipment costs.
- Maintenance Included: Since the company owns the system, they are responsible for monitoring and repairing it if anything breaks.
- Immediate, Small Savings: Your monthly lease payment or PPA rate is typically set slightly lower than your current utility bill.
Cons:
- Minimal Long-Term Savings: The third-party owner takes the majority of your savings. Most leases include an annual escalator clause (often 2% to 3.5%), meaning your lease price increases every year.
- You Lose the 30% Tax Credit: Since the leasing company owns the panels, **they claim the federal tax credit**, not you.
- Selling Your Home Becomes Difficult: Home buyers are often wary of taking over a 20- or 25-year lease contract. Many home sales fall through because buyers reject the lease transfer, forcing the seller to buy out the contract for thousands of dollars.
Side-by-Side Comparison
| Feature | Cash Purchase | Solar Loan | Solar Lease / PPA |
|---|---|---|---|
| Ownership | You own the system | You own the system | Third-party company owns it |
| Upfront Cost | Full system price ($15k–$25k) | $0 down options common | $0 down |
| Who gets the 30% tax credit? | You | You | The leasing company |
| 25-Year Net ROI | Highest ($20,000–$40,000+) | High ($15,000–$30,000) | Lowest (Often under $5,000) |
| Impact on Home Sale | Positive (increases value) | Neutral (must pay off loan) | Negative (lease transfer hassle) |
The Verdict: Buy If You Can
If you have the tax liability to claim the 30% federal credit and can afford cash or secure a low-interest solar loan, buying is always the superior financial decision. It maximizes your savings, adds home equity, and avoids home transfer headaches.
Leasing or PPAs should only be considered if you want the peace of mind of third-party maintenance, do not qualify for a loan, and have zero federal tax liability (meaning you cannot benefit from the 30% credit anyway).
Frequently Asked Questions
What is a PPA escalator?
An escalator is a clause in a solar lease or PPA that increases the price you pay for power by a fixed percentage (typically 2.9% per year). While your initial rate is cheaper than the utility, after 10-15 years, the lease price may end up higher than current utility rates.
Can I buy out my solar lease early?
Most lease agreements allow a buyout, but only after a certain period (e.g., 5 or 7 years). The buyout price is determined by a "Fair Market Value" assessment, which is often significantly higher than what a new system would cost.
