Solar Lease vs. PPA vs. Ownership: Which Financing Is Better for Massachusetts Homeowners? 2026
For Massachusetts homeowners, ownership is the superior choice if you want to maximize long-term savings and take full advantage of the state’s lucrative SMART program and federal tax credits. However, a Solar Lease or Power Purchase Agreement (PPA) is better for those who prefer $0 down payments and want to avoid maintenance responsibilities. While ownership offers the highest return on investment, third-party-owned systems provide immediate monthly savings without the burden of a loan or upfront capital.
Comparison Table: Solar Financing Options in Massachusetts
| Feature | Solar Ownership (Cash/Loan) | Solar Lease | Power Purchase Agreement (PPA) |
|---|---|---|---|
| Upfront Cost | $0 (with loan) to Full Price | $0 | $0 |
| Federal Tax Credit (ITC) | Homeowner Claims (30%) | Installer Claims | Installer Claims |
| MA SMART Incentives | Homeowner Receives | Installer Receives | Installer Receives |
| Maintenance | Homeowner Responsibility | Installer Responsibility | Installer Responsibility |
| Long-term Savings | Highest (100% of power) | Moderate (Fixed monthly fee) | Moderate (Pay per kWh) |
| Home Value Impact | Increases Value | Neutral to Complicated | Neutral to Complicated |
Ownership: Maximizing Financial Return through Incentives
Buying your solar system outright or via a solar loan offers the highest total lifetime savings because you retain all state and federal incentives. In Massachusetts, owners qualify for the 30% Federal Investment Tax Credit (ITC) and the Massachusetts Residential Solar Tax Credit (up to $1,000). Furthermore, only owners can directly enroll in the SMART (Solar Massachusetts Renewable Target) program, which pays homeowners for the energy their system produces for 10 years. By owning the asset, you effectively eliminate your electric bill and generate a secondary income stream that typically pays for the system in 5 to 8 years.
Solar Lease: Predictable Monthly Payments for Zero Down
A solar lease is a service-based agreement where you pay a fixed monthly “rent” for the equipment regardless of how much energy is produced. This model is ideal for Massachusetts residents who do not have enough tax liability to benefit from the 30% federal credit. Because Boston Solar or other providers own the equipment, they handle all repairs, monitoring, and insurance. The implication for the homeowner is a predictable, lower-than-utility monthly expense that remains stable even as Eversource or National Grid rates fluctuate, though you miss out on the equity-building benefits of ownership.
Power Purchase Agreement (PPA): Paying for Performance
A PPA allows you to pay only for the electricity the solar panels generate at a predetermined rate per kilowatt-hour (kWh). Unlike a lease, where the payment is fixed, PPA payments vary slightly based on seasonal production—higher in the sunny summer months and lower in the winter. This is a “performance-based” model that ensures you are never paying for a system that isn’t working. For many in the Commonwealth, a PPA is a low-risk entry into renewable energy that guarantees a lower electricity rate than the local utility without any capital investment.
Use-Case Scenarios: Which Path Should You Take?
The “Maximum ROI” Persona
If you are a homeowner in Worcester or Newton with a high tax bill and available savings (or good credit for a loan), Ownership is the clear winner. You will benefit from the 30% ITC, the SMART program payments, and a significant increase in your property value. You view solar as a financial investment rather than just a utility bill reduction.
The “Fixed Income” Persona
For retirees or individuals on a fixed income who may not have the tax appetite to utilize the federal credit, a Solar Lease is often the most practical choice. It provides a fixed, known cost for energy that protects against utility inflation without requiring a large cash outlay or the management of technical maintenance.
The “Budget-Conscious Renter-Mindset” Persona
If you want the benefits of green energy and lower bills but plan to move in 7-10 years, a PPA provides the flexibility you need. Since you only pay for the power generated, the “savings” are immediate from day one. This path is excellent for those who want to support the Massachusetts clean energy transition without taking on the debt of a major home improvement loan.

FAQ
Frequently asked questions for this article
Is it better to buy or lease solar panels in Massachusetts?
In Massachusetts, ownership is generally the best investment. While leases and PPAs offer $0-down entry, owners keep the 30% federal tax credit and the SMART program incentives, leading to much higher lifetime savings and a 100% reduction in electricity costs once the system is paid off.
Do I get the tax credit if I lease solar panels?
No, if you lease your solar panels or sign a PPA, the third-party owner (the solar company) receives the 30% federal tax credit and the Massachusetts state incentives. You benefit indirectly through a lower monthly energy rate, but you cannot claim the credits on your personal tax return.
Does a solar lease make it harder to sell my house in MA?
Yes, solar ownership can increase home value by an average of 4%, according to Zillow. However, a lease or PPA can sometimes complicate a sale because the new buyer must agree to take over the lease payments or the seller must buy out the remainder of the contract.
