How Does Solar Financing Work in Massachusetts

In Massachusetts, solar financing has become one of the primary ways homeowners and businesses can invest in renewable energy without having to make large upfront payments. Rather than paying cash in full for a new solar system, residents can use a solar loan, solar lease, or power purchase agreement (PPA) to spread the cost over time. These financing arrangements make solar ownership or participation attainable for a much broader range of households.

When a homeowner pays cash, they immediately own the system and qualify for all available solar incentives, such as the federal 30% Investment Tax Credit (ITC). But Massachusetts adds another layer of financial support through local rebates, state tax breaks, and performance-based rewards. Financing simply provides a way to access those benefits without depleting savings.

The state’s progressive energy goals have made solar adoption especially appealing. Massachusetts aims for net-zero greenhouse gas emissions by 2050 and operates one of the most robust incentive frameworks in the country. These include:

  • Federal ITC (30%) for owned systems
  • Residential Renewable Energy Income Tax Credit (15% of the system cost, up to $1,000)
  • Massachusetts Sales and Use Tax Exemption for solar equipment
  • Property Tax Exemption on the added home value from a solar system
  • SMART Program (Solar Massachusetts Renewable Target): pays homeowners a fixed rate per kilowatt-hour generated over ten years

Together, these programs dramatically reduce total solar costs, and financing structures make it possible to benefit from them immediately.

Solar Financing Options in Massachusetts

Massachusetts residents can choose from multiple solar financing paths, each with its own structure and long-term outcome. The four dominant options are direct cash purchases, solar loans, solar leases, and power purchase agreements (PPAs), which fall under third-party ownership (TPO).

1. Paying in Cash

Paying cash yields the highest lifetime savings and gives the owner full control of the system. However, a typical 6 to 7kW residential solar installation in Massachusetts costs between $18,000 and $24,000, which may be out of reach for some homeowners.

2. Solar Loan

A solar loan allows for immediate installation and ownership, with repayment terms ranging from 5 to 20 years. Homeowners pay interest but still receive all state and federal incentives. Because Massachusetts has some of the highest electricity prices in New England, averaging around 32¢ per kWh in 2025, monthly savings can offset most or all of the loan payments.

3. Solar Lease

Under a solar lease, the homeowner rents the equipment from a third party for a fixed monthly fee. The provider handles upkeep and performance monitoring. Leases are appealing because they require no upfront cost, but they do not qualify the lessee for any tax benefits or solar incentives since ownership stays with the provider.

4. Power Purchase Agreement (PPA)

A power purchase agreement, or PPA, lets the homeowner buy the electricity generated by the system at a predetermined rate. This cost is usually 10 to 25% below the local utility price. The third party owns the panels and maintains them throughout the contract term, which often runs 15 to 25 years.

Comparison of Solar Financing Methods in Massachusetts

Option Type Ownership Initial Outlay Incentive Eligibility Contract Length Payment Basis Typical Long-Term Savings
Cash Payment Homeowner Full upfront Eligible for all None None (fully paid) Highest overall return
Solar Loan Homeowner Low to moderate Eligible for all 5–20 years Fixed monthly payment Strong—builds equity
Solar Lease Third Party None Not eligible 15–25 years Fixed lease fee Moderate, predictable
PPA Third Party None Not eligible 15–25 years Per kWh produced Variable—linked to output

In Massachusetts, roughly half of all residential solar installations are financed through loans, while about a third use TPO models such as leases and PPAs.

Types of Solar Loans in Massachusetts

There are multiple ways to structure a solar loan in Massachusetts, depending on the lender, borrower profile, and desired term length. Loans can be secured, backed by collateral such as home equity, or unsecured, based solely on credit history.

Secured Solar Loans

A secured loan attaches the borrowed amount to an asset, most commonly real estate. These loans carry lower interest rates, usually 4% to 6%, and allow for longer repayment periods, sometimes up to 20 years. The trade-off is that missing payments can endanger the collateral.

Unsecured Solar Loans

Unsecured loans do not require any collateral and are based solely on creditworthiness. Interest rates are slightly higher, often 6% to 9%, but approval is much faster. Borrowers with high credit scores can still qualify for favorable terms, while those with average scores may pay more in interest over time.

Comparison of Secured vs. Unsecured Solar Loans

Loan Category Collateral Typical Interest Term Range Processing Time Primary Advantage Typical Borrower Profile
Secured Yes (home or property) 4%–6% 10–20 yrs Slower Lower monthly payments Established homeowners
Unsecured None 6%–9% 5–15 yrs Faster Quick approval, flexible Renters or new buyers

Many Massachusetts homeowners use unsecured solar loans through credit unions or clean-energy lending programs to avoid tying up home equity. Others prefer secured financing for the lower rates and extended payback window.

How to Find the Best Solar Loans in Massachusetts

Finding the best solar loan means identifying the financing terms that align with your budget, timeline, and expected savings. Massachusetts homeowners should compare multiple offers to evaluate differences in rate structure, repayment flexibility, and incentive compatibility.

Interest rates on solar loans in the state typically fall between 4% and 8%, depending on credit score and lender. Borrowers with strong credit histories (above 700) can often secure rates near the lower end of that range. Loan terms between 10 and 15 years are common, balancing manageable monthly payments with reasonable total interest. The best solar loan is one that has no prepayment penalty, offers predictable fixed payments, and keeps interest below 6%.

The total financial outcome also depends on how incentives interact with the loan. A homeowner who finances a $20,000 system at 5% interest over 15 years will still receive a $6,000 federal ITC, plus potential state tax credits and SMART payments, which can collectively cover a significant portion of the system’s net cost.

Example: Solar Loan Cost Scenarios

System Price Loan Style Loan Duration Annual Percentage Rate (APR) Estimated Monthly Payment Lifetime Interest Paid Post-Incentive Cost (after ITC)
$18,000 Secured 15 years 5% ≈$143 $7,740 $12,600
$18,000 Unsecured 10 years 7% ≈$209 $7,080 $12,600

Both options generate overall savings since monthly energy cost reductions in Massachusetts, often $100 or more, help offset repayment.

Can I Get Free Solar Panels in Massachusetts?

While “free solar” offers are often advertised, they typically refer to third-party ownership (TPO) models such as solar leases and power purchase agreements (PPAs). These options eliminate upfront payment requirements but shift system ownership to a separate entity.

Under a solar lease, homeowners pay a predictable monthly fee for the use of solar equipment installed on their property. The provider maintains and insures the panels, while the homeowner benefits from lower electric bills. The disadvantage is that the homeowner does not qualify for solar incentives like the ITC or SMART payments.

A power purchase agreement (PPA) differs in that the homeowner pays only for the electricity produced, measured per kilowatt-hour (kWh). PPAs can yield higher savings if the household uses more electricity or if system output remains consistent throughout the year.

Comparison: Lease vs. PPA in Massachusetts

Key Feature Solar Lease Power Purchase Agreement (PPA)
System Ownership Third party Third party
Payment Form Flat monthly fee Variable per-kWh charge
Maintenance Responsibility Provider Provider
Upfront Cost $0 $0
Eligible for Tax Incentives No No
Cost Predictability High Moderate
Energy Savings Potential Fixed savings Usage-dependent savings

These third-party models are beneficial for residents who cannot secure traditional financing or prefer predictable energy pricing without maintenance obligations. They make solar accessible to renters, new homeowners, or households with lower credit scores.

How to Get Solar Financing in Massachusetts

Securing solar financing in Massachusetts involves several straightforward steps that vary depending on whether you plan to own the system or enter a lease or PPA agreement. The first step is to assess your property’s solar potential, energy use, and eligibility for incentives. After this evaluation, you will receive a project proposal detailing installation costs, available programs, and recommended financing types.

If you opt for a solar loan, the next step is to apply for financing through a participating lender or a clean-energy lending program. Approval depends on credit history, income, and overall debt-to-income ratio. A credit score of around 650 or higher generally qualifies for favorable rates. Once the loan is approved, you will sign the financing agreement specifying repayment duration, interest rate, and monthly obligation. Installation begins after the contract is finalized, and upon system activation, you can file for federal and state solar incentives. The 30% ITC credit and Massachusetts’ performance-based SMART payments substantially reduce the loan’s long-term cost.

For those pursuing a solar lease or PPA, the process is simpler. The third-party provider evaluates the site, installs the system, and assumes full responsibility for operation and maintenance. The homeowner signs a long-term agreement to pay either a fixed monthly lease or a per-kWh rate under the PPA. The provider, not the homeowner, receives the incentives and tax credits, but the homeowner benefits from lower electricity expenses immediately after the system is connected.

A solar loan appears on your credit report much like any other installment loan. Making consistent, on-time payments can strengthen your credit profile, while missed payments may have a negative impact. Because of this, selecting a financing plan with manageable monthly payments is essential.

Massachusetts’ well-developed renewable-energy infrastructure and strong state support make it one of the best places in the country to finance solar. Residents can choose from flexible ownership, leasing, or power purchase agreement structures, each providing a path to clean energy independence. Whether through an affordable solar loan or a no-money-down third-party option, solar financing empowers Massachusetts households to reduce energy costs while contributing to the state’s clean-energy transformation.
