Massachusetts SMART 3.0 Guide: Solar Incentives Explained (2026)
Massachusetts SMART 3.0 Guide: Solar Incentives Explained (2026)
Massachusetts has long been one of the nation’s leaders in solar energy adoption, and the Solar Massachusetts Renewable Target (SMART) Program has played a major role in that success. The newest version of the program—SMART 3.0—is designed to continue driving solar growth while helping homeowners, businesses, and communities reduce their electricity costs.
With electricity prices rising rapidly across Massachusetts and the demand for clean energy increasing, SMART 3.0 is now the most important financial incentive for solar installations in the state.
In this guide, we’ll explain exactly how SMART 3.0 works, how much it pays, who qualifies, and why it makes solar one of the smartest financial investments for Massachusetts homeowners in 2026.
What Is the SMART Program in Massachusetts?
The Solar Massachusetts Renewable Target (SMART) Program is the Commonwealth’s primary solar incentive program, administered by the Massachusetts Department of Energy Resources (DOER). The program pays solar system owners a performance-based incentive for every kilowatt-hour (kWh) of electricity their solar system generates.
Unlike traditional solar rebates that provide a one-time payment, the SMART program rewards solar production over time. Once enrolled, participants receive monthly payments or bill credits based on the amount of electricity their system produces.
The program applies to solar installations connected to the state’s three investor-owned utilities:
- Eversource
- National Grid
- Unitil
These utilities distribute the incentive payments after a project is approved and interconnected.
The goal of SMART is to:
- Increase solar energy generation across Massachusetts
- Reduce electricity costs for residents and businesses
- Encourage development of clean, renewable energy
- Support statewide climate and emissions goals
What Is SMART 3.0?
SMART 3.0 is the newest version of the program, launched in 2025 as an update to the earlier SMART 1.0 and SMART 2.0 programs.
The redesign modernized the incentive structure to ensure the program remains sustainable while continuing to encourage solar development across the state.
SMART 3.0 introduced several major changes:
- A new flat incentive rate for residential systems
- Annual program adjustments instead of declining capacity blocks
- Expanded incentives for low-income households
- New requirements for community solar participation
- Updated capacity allocations for solar projects statewide
The program is expected to deliver hundreds of millions of dollars in savings to Massachusetts ratepayers while continuing to expand solar adoption across the state.
How SMART 3.0 Works
SMART 3.0 pays solar system owners based on the actual electricity their system generates.
Here’s how the process works:
1. Install a Solar System
A solar installation is completed and connected to the local electric grid through one of Massachusetts’ utility providers.
2. Apply for SMART
Your solar installer submits a SMART application on your behalf during the program’s enrollment period.
3. Lock in Your Incentive Rate
Once approved, your SMART incentive rate is locked in for the entire program term.
4. Generate Solar Power
Your solar system produces electricity throughout the year.
5. Receive Monthly Payments
Each month, you receive a payment or utility bill credit based on the number of kilowatt-hours your system produced.
These incentives are separate from and in addition to net metering credits, which compensate you for excess electricity sent back to the grid.
SMART 3.0 Incentive Rates (Residential Solar)
Under SMART 3.0, most residential solar systems (25 kW or smaller) receive a base incentive of approximately $0.03 per kWh generated.
For qualifying low-income households, the incentive doubles to:
$0.06 per kWh
These payments continue for 20 years, creating a long-term revenue stream that significantly improves the financial return of a solar installation.
Example
A typical Massachusetts home solar system produces around 12,500 kWh per year.
SMART payments would equal:
12,500 kWh × $0.03 = $375 per year
Over a 20-year SMART term, that equals approximately:
$7,500 in additional solar income
This is on top of:
- Net metering bill credits
- Massachusetts tax incentives
- Electricity savings from self-generated power
Additional SMART 3.0 Adders
SMART 3.0 also includes bonus incentives (called adders) for projects that deliver additional benefits to the grid or community.
Common SMART adders include:
Battery Storage Adder
Solar systems paired with battery storage may receive an additional incentive per kWh generated.
Low-Income Adder
Projects serving low-income households receive higher compensation rates.
Community Solar Adder
Community Shared Solar facilities can earn additional incentives while providing guaranteed energy bill savings to participants.
Solar Canopy / Carport Adder
Solar installed over parking lots or structures can qualify for higher incentives.
Agricultural Solar (Dual-Use)
Solar systems that allow farming beneath the panels receive special incentives to preserve farmland.
These adders can significantly increase total incentive payments, especially for larger or specialized solar projects.
Net Metering and SMART Work Together
One of the reasons solar remains financially attractive in Massachusetts is that SMART incentives stack with net metering benefits.
Net metering allows solar owners to send excess electricity back to the grid and receive bill credits for that energy.
For residential systems up to 25 kW, Massachusetts typically provides full retail net metering credits, meaning the value of exported electricity is roughly equal to the price you pay for electricity from the grid.
When combined with SMART incentives, solar system owners receive:
- Electricity bill savings
- Monthly SMART payments
- Net metering credits
- Long-term protection from rising energy prices
SMART 3.0 Program Capacity
SMART 3.0 includes an overall statewide solar capacity target measured in megawatts.
Program capacity is allocated among Massachusetts utilities based on their customer base, ensuring solar development occurs across the entire state.
Each program year includes a defined amount of solar capacity available for new projects.
Once that capacity is filled, additional projects must wait for the next program year or revised allocation.
Who Qualifies for SMART 3.0?
SMART 3.0 is available to many different types of solar installations, including:
Residential Solar
Homeowners installing rooftop solar systems.
Commercial Solar
Businesses installing solar on rooftops, parking canopies, or ground-mounted systems.
Community Solar
Large solar farms that allow residents to subscribe and receive bill credits.
Agricultural Solar
Solar installations combined with farming operations.
Low-Income Solar Projects
Programs designed to expand solar access to underserved communities.
Eligibility requirements typically include:
- Interconnection with Eversource, National Grid, or Unitil
- Approval by the Solar Program Administrator
- Compliance with Massachusetts solar regulations
- System size and project classification requirements
Why SMART 3.0 Matters in Massachusetts
SMART 3.0 plays a crucial role in maintaining Massachusetts as one of the leading solar states in the U.S.
The program:
- Encourages continued solar growth
- Helps stabilize electricity costs
- Supports job creation in the clean energy sector
- Reduces greenhouse gas emissions
- Expands access to renewable energy for residents across income levels
The program is also part of the state’s broader strategy to transition toward a cleaner, more resilient energy system.
Is SMART 3.0 Still Worth It?
Absolutely.
Even with changes in federal policy, Massachusetts still offers one of the strongest solar incentive packages in the United States.
Between SMART payments, net metering credits, tax exemptions, and electricity savings, most homeowners can recover the cost of a solar installation within 7–9 years, while enjoying decades of reduced electricity bills afterward.
As electricity prices continue rising across New England, locking in long-term solar incentives through SMART 3.0 can provide substantial financial protection for homeowners.
The Bottom Line: SMART 3.0 Makes Solar More Valuable Than Ever
The Massachusetts SMART 3.0 program ensures that solar energy remains a financially attractive investment for homeowners and businesses throughout the Commonwealth.
By paying solar system owners for the electricity their systems produce, SMART creates a reliable long-term revenue stream while accelerating the state’s transition to clean energy.
When combined with net metering and other Massachusetts incentives, SMART 3.0 makes solar one of the most powerful tools available for reducing electricity costs and gaining energy independence.
