Understanding Solar Loan, Power Purchase Agreements (PPA) and Lease Options in Solar

As solar energy becomes increasingly popular, homeowners and businesses are looking for ways to access solar power without significant upfront investment. Two common financing options are Power Purchase Agreements (PPAs) and Solar Leases. While they share similarities, they also have distinct differences that can impact long-term savings and ownership.

What is a Solar Loan?

A solar loan is a financing option that enables homeowners and businesses to purchase a solar energy system without paying the full cost upfront. Instead, the system is paid off in monthly installments, similar to a mortgage or auto loan. Once the loan is fully paid, the owner gains complete ownership of the system, along with all the financial benefits associated with it.

Key Features of a Solar Loan:

  • Ownership of the System: Unlike leases or PPAs, the borrower owns the solar panels.

  • Eligibility for Incentives: Solar loans allow access to federal and state tax credits, rebates, and incentives.

  • Flexible Loan Terms: Repayment periods typically range from 5 to 25 years.

  • Various Loan Types: Secured (home equity loans) or unsecured (personal loans) options are available.

  • Potential for Increased Property Value: A fully owned solar system can boost home resale value.


What is a Power Purchase Agreement (PPA)?

A Power Purchase Agreement (PPA) is a financial arrangement where a solar provider installs, owns, and maintains a solar energy system on a homeowner’s or business’s property. In exchange, the property owner agrees to purchase the electricity generated by the system at a predetermined rate, usually lower than the utility's standard rates.

Key Features of a PPA:

  • No Upfront Costs: The solar provider covers installation and maintenance costs.

  • Lower Energy Bills: The electricity rate is often lower than traditional utility rates.

  • Fixed or Escalating Rates: Some PPAs offer fixed rates, while others have slight annual increases.

  • No Maintenance Responsibility: The provider takes care of system upkeep and repairs.

  • Long-Term Agreement: PPAs typically last 10-25 years, with options to renew or purchase the system later.

Pros of a PPA:

  • Immediate savings on electricity costs.

  • No maintenance or repair worries.

  • Predictable energy costs over the contract period.

Cons of a PPA:

  • No ownership benefits, such as tax credits or incentives.

  • Long-term commitment that may complicate property sales.

  • Potential for rate increases over time.

What is a Solar Lease?

solar lease is similar to a PPA but instead of purchasing electricity, the homeowner or business rents the solar panels for a fixed monthly fee. This fee remains consistent regardless of how much electricity is produced.

Key Features of a Solar Lease:

  • Fixed Monthly Payment: Instead of paying for energy used, the customer pays a lease fee for the system.

  • No Upfront Costs: The provider covers installation and maintenance expenses.

  • No Maintenance Costs: The leasing company handles system upkeep.

  • Typically 20-25 Year Term: Leases are long-term but may include buyout or renewal options.

Pros of a Solar Lease:

  • Predictable monthly payments.

  • No large initial investment.

  • Maintenance and repairs covered by the provider.

Cons of a Solar Lease:

  • No ownership or equity in the system.

  • No eligibility for federal or state solar incentives.

  • Transferability issues when selling the property.

Choosing Between a PPA and a Solar Lease

When deciding between a PPA and a lease, consider the following factors:

  • Electricity Usage: If you want to pay for power as you use it, a PPA may be better. If you prefer a fixed payment, a lease might be preferable.

  • Long-Term Savings: PPAs often provide more savings over time, especially with lower per-kWh rates.

  • Home Ownership Plans: If you plan to sell your home, check if the agreement allows easy transferability.

  • Available Incentives: Owning a system may provide tax benefits unavailable with PPAs or leases.

Final Thoughts

Both PPAs and solar leases provide opportunities for homeowners and businesses to adopt solar energy with minimal upfront costs. However, they come with trade-offs related to ownership, long-term savings, and transferability. Understanding these differences can help you make an informed decision that aligns with your financial and energy goals.
