Leases vs Loans vs PPAs: Which to Choose for Your Solar Investment?

When considering solar power or other major equipment investments, one of the biggest decisions isn’t just what to buy—it’s how to pay for it. Three common financing options dominate the conversation: leases, loans, and PPAs (Power Purchase Agreements). Each option has unique pros and cons, and the right choice depends on your financial goals, risk tolerance, and long-term plans. Let’s break them down in plain language.

1. What is a Solar Lease?

A solar lease is similar to renting your solar system. You don’t own it—the leasing company does—but you get to use the power it produces.

How it works:
You pay a fixed monthly fee for the use of the solar system. The leasing company installs, owns, and maintains it.

Pros:

• Low or no upfront cost
• Maintenance & repairs covered by the provider
• Predictable monthly payments

Cons:

• You don’t own the system, so you miss out on tax credits or incentives
• Long-term payments may add up
• Can complicate home sales

Best for: Homeowners or businesses who want to go solar with minimal upfront costs and don’t want to handle maintenance.

2. What is a Solar Loan?

A solar loan lets you finance the purchase of your solar system, just like buying a car with a loan.

How it works:
You borrow money from a bank, credit union, or solar lender and repay it over time, usually 5–20 years.

Pros:

• You own the system and keep all incentives & tax credits
• Increases property value
• After the loan is paid, you enjoy free solar power (except minimal maintenance)

Cons:

• Requires good credit to get low interest rates
• You’re responsible for maintenance after warranties expire
• Higher upfront responsibility than leases or PPAs

Best for: Those who want to own their solar system, benefit from incentives, and have the credit or cash flow to handle loan payments.

3. What is a PPA (Power Purchase Agreement)?

A PPA is like a lease but with payments based on the amount of electricity your system produces.

How it works:
The solar company installs and owns the system. You agree to buy the electricity it generates at a fixed rate per kWh, usually lower than your utility rate.

Pros:

• No upfront cost
• Pay only for the power you use
• Lower electricity rates than the grid in most cases

Cons:

• You don’t own the system, so no tax credits
• Long-term contracts (often 15–25 years)
• Price escalators may increase costs over time

Best for: Customers who want immediate savings without ownership responsibilities and are comfortable with a long-term agreement.

Quick Comparison Table

How to Choose the Right Option

• Choose a Lease if… you want a predictable payment, zero maintenance responsibility, and no upfront costs—but don’t mind not owning the system.
• Choose a Loan if… you want full ownership, to maximize incentives, and are ready for a long-term investment.
• Choose a PPA if… you want to pay only for the electricity you use, avoid maintenance, and lock in rates without a big upfront bill.

Final Thoughts

There’s no one-size-fits-all answer. If ownership and long-term savings matter most, loans are your best bet. If you prefer a hands-off, low-risk approach, leases or PPAs might make more sense. Before deciding, compare quotes, read contracts carefully, and consider your financial goals for the next 15–25 years.
