What Exactly Is a Solar Power Purchase Agreement (PPA)?

A solar power purchase agreement (PPA) is a financial arrangement in which a developer designs, permits, and installs a solar energy system on a customer's property, often with minimal or no upfront costs. The developer then sells the electricity the system generates to the customer at a fixed rate, typically lower than the local utility's retail rate.

This reduced electricity price offsets the customer's reliance on grid electricity. At the same time, the developer benefits from income generated by selling the electricity and accessing tax credits and incentives associated with the system. Typically lasting 10 to 25 years, the PPA contract ensures that the developer remains responsible for operating and maintaining the solar system throughout the agreement. At the end of the contract term, the customer may have the option to renew the PPA, request the removal of the system by the developer, or even choose to purchase the solar energy system outright.

PPA Market Adoption and Policy

Power Purchase Agreements (PPAs) offer an attractive solution for customers by eliminating upfront costs and streamlining the solar PV system installation process. Certain states face regulatory and legislative challenges that aim to classify developers as electric utilities, potentially affecting the PPA model. An alternative to PPAs is a solar lease, which operates similarly but does not involve the sale of electric power.
Instead, customers lease the system, similar to leasing an automobile. In both cases, a third party owns the system while the host customer enjoys the benefits of solar energy with minimal or no upfront expenses. These third-party financing models have gained significant popularity. This upward trend continues in various states that have embraced third-party financing models.

PPA Considerations

Solar Renewable Energy Credits (SRECs): Serve as proof that a certain amount of electricity is generated using solar energy. Load-serving entities, typically regulated utilities, buy and sell SRECs to meet state-level renewable energy standards. Consumers may also voluntarily purchase SRECs for marketing claims or other purposes. In most Power Purchase Agreements (PPAs), the developer retains ownership of the SRECs. When entering into a PPA, solar customers must understand who owns and can sell the SRECs generated by the PV system, the associated risks, and the tradeoffs in terms of PPA pricing.

Solar Financing Options: While third-party financing models, such as PPAs and solar leases, offer numerous benefits, purchasing a PV system outright has advantages. It’s essential for anyone considering solar PV installation to carefully evaluate each financing option available to determine the best fit for their specific circumstances.

Solar Site Upgrades: While the developer is responsible for the installation, operation, and maintenance of the solar PV system, the host customer may need to invest in property upgrades to support the solar system's installation, reduce installation costs, or comply with local regulations. These upgrades may include roof repairs or tree trimming to prevent shading of the PV system.

Potential Property Tax Implications: While a PV system can increase the property value of a site, there is also a possibility of higher property taxes when the property's value is reassessed. It's important to note that different states have varying policies regarding potential property tax increases from solar installations.

Considering these factors will help you make informed decisions about SRECs, financing options, necessary site upgrades, and potential property tax implications when exploring solar PV installations.

PPA Contracts and Early Termination Fees

A Power Purchase Agreement (PPA) is a legally binding commitment that spans 10 to 25 years. It is crucial to thoroughly review the contract with your solar development partner or seek a second opinion, just as you would with any agreement.

Pay close attention to the terms and conditions, particularly clauses related to costs, contract duration, and early termination fees (ETFs). While most PPAs include an option for early termination, it can come at a significant cost. Therefore, it is essential to carefully evaluate the early termination costs before signing the agreement.

If you plan to move before the PPA term ends, explore the possibility of transferring the agreement to the new homeowner or relocating the solar system to your new residence. Reviewing your PPA agreement for specific terms will be necessary.

What Are the Pros of a Solar PPA?

Solar Power Purchase Agreements (PPAs) offer several benefits that make them an attractive option for adopting solar energy:

Less financial risk: With a solar PPA, the developer assumes the financial risk associated with the installation, operation, and maintenance of the solar system. This relieves the host customer of the upfront costs and ongoing expenses, providing greater financial stability and predictability.

Little to no upfront money is needed: A vital advantage of a solar PPA is the minimal upfront investment required. The developer covers the costs of designing, permitting, financing, and installing the solar PV system, eliminating the need for the host customer to provide significant capital upfront.

No need to take out a loan: Unlike purchasing a solar system outright or financing it through a loan, a solar PPA does not require the customer to secure a loan or take on additional debt. This makes solar energy accessible to a broader range of customers who may not qualify for traditional financing options.

Lower monthly energy bills: By entering into a solar PPA, the host customer benefits from purchasing solar electricity at a fixed or predetermined rate, often lower than the local utility's retail rate. This leads to immediate savings on monthly energy bills, providing long-term cost benefits.

Less time commitment for planning and design: Since the developer is responsible for the planning, designing, and installing of the solar system in a PPA, the host customer can save significant time and effort compared to self-installation or managing the project independently.

Increase home value: Studies have shown that properties with solar PV systems tend to have higher resale values. By entering into a solar PPA, homeowners can increase the value of their property while boosting equity without the need for a substantial upfront investment.

Gain energy independence: With a solar PPA, the host customer can generate clean, renewable energy on-site, reducing reliance on traditional energy sources and contributing to a more sustainable future. It allows for greater energy independence and a reduced carbon footprint.

Solar PPAs offer numerous advantages, including reduced financial risk, low, upfront costs, savings on monthly energy bills, convenience in planning and design, increased home value, and the opportunity to achieve energy independence. These benefits make solar PPAs an appealing choice for those looking to embrace solar energy without the burdens of financing or installation.

What Are the Cons of a Solar PPA?

While solar Power Purchase Agreements (PPAs) offer several benefits, as seen above, it's essential to consider the potential drawbacks associated with this financing model:

Not qualified for tax incentives and rebates: In a solar PPA, the developer typically retains ownership of the solar system, which means the host customer may not be eligible for tax incentives, rebates, or other financial benefits associated with solar energy installations. These incentives often require the system owner to claim them.

Committed to a long-term contract: When entering into a solar PPA, the host customer agrees to a long-term contract that typically spans 10 to 25 years. While this provides stability and predictable energy costs, it also means being locked into the agreement for an extended period. Early termination of the contract may result in fees or penalties.

Ineligible for SREC income: Solar Renewable Energy Credits (SRECs) can be an additional source of income for solar system owners. However, in a PPA, SRECs are usually owned by the developer, so the host customer does not have the opportunity to benefit from selling these credits.

Fees may increase over time: Although the PPA may offer lower energy costs initially, reviewing the contract terms thoroughly is essential. Some PPAs include escalator clauses, which gradually increase the electricity price. This can result in higher fees as the contract progresses.

Homeowners may still need to pay for site upgrades: While the developer takes care of system installation, operation, and maintenance, the host customer may be responsible for making additional investments in their property. This can include repairs, upgrades, or modifications to support solar system installation.

Homeowners may face higher property taxes: Installing a solar system can increase a property's assessed value, leading to higher property taxes. The specific property tax policies vary by location, and it's essential to consider the potential impact on overall homeownership costs.

Homeowners may incur early termination fees: If the host customer needs to terminate the PPA contract before its scheduled end, early termination fees may apply. These fees can be substantial and should be carefully evaluated before signing the agreement.

When considering a solar PPA, it's crucial to thoroughly review the contract terms and understand the potential limitations regarding tax incentives, SRECs, fees, site upgrades, property taxes, and early termination fees. This will help make an informed decision based on individual financial circumstances and goals.


Is a Solar PPA the Right Move for You?

Whether a solar Power Purchase Agreement (PPA) suits you depends on your specific circumstances and preferences. For some individuals, a solar PPA can be a suitable choice, especially if they are interested in solar power but prefer to avoid owning the system and are comfortable paying another company for the generated power.

It is crucial to thoroughly comprehend all the terms and conditions of the contract before signing, as modifications can be challenging once the agreement is in place. Taking the time to understand the PPA fully ensures you can make an informed decision and avoid surprises.
