Solar Financing Options: Loans, Leases, and Power Purchase Agreements Explained

Updated: Apr 7, 2023

As solar energy becomes increasingly popular, more financing options are becoming available to help property owners invest in solar power systems. Choosing the right financing option can be crucial to the success of your solar project, as it can significantly impact your overall costs and long-term savings. In this blog post, we'll explore the most common solar financing options: solar loans, leases, and power purchase agreements, to help you make an informed decision.


Solar Loans

Solar loans are a popular choice for financing solar panel installations. These loans function similarly to other home improvement loans, allowing you to borrow money to cover the cost of your solar system and repay it over time. Solar loans offer several advantages, including:

  • Ownership: With a solar loan, you own the solar system, which can increase your property value.

  • Tax benefits: As the system owner, you can benefit from federal and state tax credits and incentives.

  • Flexible terms: Solar loans come with various term lengths and interest rates, allowing you to choose the option that best fits your budget.

However, it's essential to consider the interest rates and loan terms, as they can affect your overall savings.


Solar Leases

With a solar lease, you essentially rent the solar system from a third-party company that owns and maintains it. The company installs the system on your property, and you pay a fixed monthly fee to use the generated electricity. Some advantages of solar leases include:

  • No upfront costs: Solar leases often require little to no money down, making them an attractive option for those with limited budgets.

  • Maintenance included: The leasing company is responsible for maintenance, repairs, and monitoring, reducing your responsibilities as the homeowner.

  • Predictable costs: Monthly lease payments are typically fixed, allowing you to budget more easily.

However, solar leases may not offer the same long-term savings as owning a solar system, and you may miss out on tax credits and incentives.


Power Purchase Agreements (PPAs)

A power purchase agreement is similar to a solar lease, with one key difference: instead of paying a fixed monthly fee, you pay for the electricity your solar system generates at a predetermined rate. PPAs offer several benefits:

  • No upfront costs: Like solar leases, PPAs often require little to no money down.

  • Maintenance included: The PPA provider is responsible for system maintenance and repairs.

  • Protection against rising energy costs: With a PPA, you lock in a specific rate for the electricity your solar system produces, potentially saving money if energy costs rise.

However, as with solar leases, you may miss out on tax credits and incentives, and long-term savings may be lower than with system ownership.


When considering solar financing options, it's crucial to weigh the pros and cons of each and determine which best aligns with your financial goals and circumstances. Solar loans, leases, and power purchase agreements each have their unique advantages and drawbacks, so take the time to research and compare them to make the most informed decision for your solar project.
