Solar leases vs. solar PPAs: What Are The Differences

Solar leases vs. solar PPAs

While the cost of solar technology has dropped significantly in recent years, the total bill for buying and installing a full system can still be pretty steep. For many, this large upfront expense is a major hurdle to switching to solar energy.

Here's where solar leases and Power Purchase Agreements (PPAs) come into play, offering a smoother path. These options are perfect for those looking to dodge the big initial investment and the rising interest rates associated with solar loans. By opting for a lease or a PPA, you essentially partner with a provider who takes care of installing the solar panels on your property. Your role? Simply to pay a manageable monthly fee.

This arrangement not only makes going solar more accessible but also frees you from worrying about the complexities of installation and maintenance. Whether you choose a lease, where you pay for using the solar system, or a PPA, where you pay for the power it produces, you're stepping into a future of cleaner, more sustainable energy without the financial strain.

The Basics of Solar Leases

A solar lease is a financial agreement where a homeowner partners with a solar provider to install solar panels on their property. Under this arrangement, you don't own the solar system; instead, you pay a fixed monthly fee to lease the equipment. This setup eliminates the hefty initial investment required to purchase a solar system outright and covers the installation and maintenance, making it an attractive option for many homeowners.

The essence of a solar lease is simplicity and accessibility. It allows you to benefit from solar energy without the complexities and financial burden of system ownership. The solar company takes care of everything – from installation to maintenance and repairs, ensuring the system operates efficiently throughout the lease term.

Pros and Cons of Solar Leases


  • No Upfront Costs: One of the most appealing aspects of solar leases is the elimination of upfront costs. Installing a solar system can be expensive, and a lease makes solar accessible without the initial financial strain.

  • Maintenance Coverage: The responsibility for maintaining and repairing the system falls on the solar provider, not you. This means less worry about potential issues or the need for upkeep.

  • Fixed Monthly Payments: Solar leases offer predictability with fixed monthly payments, making budgeting easier for homeowners.

  • Potential Savings: While you're not eliminating your energy bill, you could still see a reduction in overall monthly utility costs, depending on the terms of your lease and your energy usage.


  • Missed Incentives: Leasing means you miss out on solar incentives such as the federal tax credit, which can significantly reduce the cost of solar installation. These benefits go to the system's owner – in this case, the leasing company.

  • Escalator Clauses: Many solar leases include escalator clauses, which gradually increase your monthly payment over time. This could potentially offset any savings on your utility bill.

  • Long-Term Commitment: Solar leases typically last 10 to 20 years. If you move, transferring the lease to the new homeowner can be complicated.

So What Are Solar Power Purchase Agreements (PPAs)?

At its core, a Solar Power Purchase Agreement (PPA) is a financial arrangement that allows homeowners to enjoy solar energy without owning the solar system. Unlike solar leases, where you pay a fixed monthly fee for the use of solar panels, PPAs charge you for the electricity generated by the panels installed on your property. This means your monthly payment can vary based on how much energy you use.

The structure of a typical PPA is straightforward: a solar provider installs panels on your home at no upfront cost to you. In return, you agree to purchase the power produced by these panels at a predetermined rate, which is often lower than the average utility price. This agreement usually lasts between 15 to 25 years, offering a long-term solution to reduce your energy bills.

Advantages and Challenges of Solar PPAs


  • Cost Savings: One of the biggest draws of PPAs is the potential for savings. By locking in a lower rate for solar power, you can significantly reduce your monthly energy bills.

  • Zero Upfront Costs: Like solar leases, PPAs require no initial investment. The solar company covers the cost of panels, installation, and maintenance.

  • Maintenance-Free: The responsibility for maintaining and repairing the solar system lies with the provider, not you. This means you can enjoy the benefits of solar energy without the hassle of upkeep.


  • Variable Payments: Since your bill is tied to energy usage, months of higher consumption will lead to higher charges. This variability can make budgeting a bit trickier.

  • Missed Incentives: Entering into a PPA means you forfeit direct access to solar incentives like the federal tax credit, which go to the system's owner (the solar provider).

  • Contract Length and Escalators: PPAs often come with long-term commitments and may include escalator clauses that increase the rate you pay over time, potentially eroding some of the cost savings.

Common Concerns and Misconceptions:

Many homeowners worry about the implications of a PPA if they decide to sell their home. It's important to know that PPAs can be transferred to the new homeowner, making it a manageable part of the home-selling process. Additionally, the fear of escalating payments can be mitigated by carefully reviewing your PPA contract for escalator clauses and understanding how they impact your future payments.

Solar Leases vs. Solar PPAs

Solar leases vs. solar PPAs

Both paths offer unique advantages and considerations, making it crucial to understand their differences before making a decision.

Costs: Solar leases typically involve a fixed monthly payment, regardless of how much energy the solar system produces. This provides predictability in budgeting but may not always reflect actual energy usage. On the other hand, PPAs charge you based on the amount of electricity the solar panels generate, which can vary month to month, offering potential savings when solar production is high.

Maintenance Responsibilities: Both options relieve homeowners of maintenance concerns, as the solar provider is responsible for system upkeep. This means less worry for you about the operational health of your solar panels.

Contract Terms: Solar leases and PPAs both involve long-term agreements, usually ranging from 15 to 25 years. However, the terms can vary significantly between providers, so it's essential to read the fine print.

Benefits to the Homeowner: The immediate benefit of both solar leases and PPAs is the reduction in electricity costs without the hefty upfront investment of purchasing a solar system. However, because you don't own the system with either option, you may miss out on certain incentives like the federal solar tax credit.

Making the Right Choice for Your Home

Deciding between a solar lease and a PPA hinges on your personal energy needs, financial goals, and long-term home plans. Consider the following:

  • Energy Consumption: If your energy use is consistent, a solar lease might offer the budgeting stability you prefer. For homes with fluctuating energy needs, a PPA could provide more savings in months of high solar production.

  • Financial Planning: Evaluate your financial situation to decide whether a predictable monthly payment or a variable cost based on actual energy production aligns with your budgeting style.

  • Home Ownership Plans: If you plan to sell your home, understand how each agreement transfers to new homeowners. Some contracts may be more appealing to potential buyers.

Exploring the world of solar energy can seem like a journey through unfamiliar territory. Yet, understanding the nuances between solar leases and PPAs doesn't have to feel like deciphering a complex puzzle. Imagine having a guide who speaks your language, ready to illuminate the path that aligns perfectly with your home's energy needs and your financial aspirations.

Can I switch from a solar lease to a PPA or vice versa?

Switching between a solar lease and a PPA typically isn't straightforward due to the contractual nature of these agreements. However, some providers may offer flexibility or renegotiation options. It's essential to discuss this with your solar company.
