Massachusetts offers some of the strongest solar incentives in the nation. Between federal tax credits, the SMART 3.0 program, and net metering, homeowners can significantly reduce installation costs while maximizing long-term savings.
Get Your Incentive AnalysisWhy Massachusetts is One of the Best States for Solar
High electricity rates, strong state programs, and generous federal incentives make Massachusetts an ideal location for solar investment. Homeowners across the state are saving thousands while reducing their carbon footprint.
High Energy Costs
Massachusetts has some of the highest electricity rates in the nation. Solar panels provide immediate relief from rising utility bills while locking in predictable energy costs for decades.
Strong Incentive Programs
The combination of federal tax credits, SMART 3.0 payments, and net metering creates one of the most favorable solar investment climates in the country.
Increased Home Value
Studies show solar installations increase property values by 3-4% on average. In Massachusetts' competitive real estate market, solar is a valuable asset for future resale.
Federal Solar Investment Tax Credit (ITC)
The federal solar tax credit remains the single largest incentive available to Massachusetts homeowners.
Tax Credit Through 2032
Homeowners can deduct 30% of their total solar installation cost—including equipment, labor, and permitting—from federal taxes. This credit applies to systems placed in service through December 31, 2032.
Example: A $25,000 solar system qualifies for a $7,500 federal tax credit, reducing your net cost to $17,500.
Covers Full System Cost
The ITC applies to the entire project cost, including solar panels, inverters, mounting equipment, wiring, installation labor, permits, and even battery storage systems installed alongside solar.
No Income Limits
Unlike some state programs, the federal ITC has no income restrictions. As long as you have sufficient tax liability, you can claim the full 30% credit regardless of household income.
Massachusetts SMART 3.0 Program
The Solar Massachusetts Renewable Target (SMART) 3.0 program provides direct monthly payments for solar energy production over 20 years.
How SMART 3.0 Works
SMART 3.0, launched October 15, 2025, pays residential solar customers a fixed rate per kilowatt-hour (kWh) of electricity generated. Unlike previous versions that used declining block structures, SMART 3.0 offers predictable, flat incentive rates adjusted annually by the Massachusetts Department of Energy Resources.
- Standard Rate: $0.03/kWh for residential systems under 25 kW
- Low-Income Rate: $0.06/kWh for qualified households
- Payment Term: Monthly payments for 20 years from interconnection
- Eligible Utilities: Eversource, National Grid, and Unitil customers
- Application: Your installer submits paperwork through utility portals
Real Example: A typical 10 kW residential system producing 12,000 kWh annually earns $360/year ($0.03/kWh × 12,000 kWh) = $7,200 total over 20 years in SMART payments—paid monthly via direct check from your utility.
Note: SMART 3.0 rates are locked at enrollment and paid in addition to net metering credits. Residential systems under 25 kW are not eligible for battery storage adders under SMART 3.0, but homeowners can still add batteries for backup power and energy independence.
Understanding Your Total Incentives
Massachusetts homeowners benefit from stacking multiple incentives. Here's how they work together:
These combined incentives significantly reduce your net system cost while accelerating payback timelines.
Massachusetts Net Metering
Net metering allows you to receive full retail credit for excess solar energy sent back to the grid—one of the most valuable benefits for Massachusetts solar owners.
How Net Metering Works
When your solar system produces more electricity than your home uses, the excess energy flows back to the grid. Your utility meter literally runs backward, crediting your account at the full retail electricity rate—not a reduced wholesale rate.
Monthly Credit Banking
Excess generation credits roll over month-to-month. During high-production summer months, you build credits that offset winter usage when solar production is lower. Credits remain on your account year-round.
Full Retail Value
Massachusetts net metering provides credits equal to the full retail electricity rate—typically $0.20-$0.30/kWh depending on your utility and rate plan. This maximizes the financial value of every kilowatt-hour your system produces.
Additional State Incentives & Tax Credits
Beyond federal and SMART incentives, homeowners may qualify for additional state-level programs and local utility rebates.
State Tax Credits
Many states offer additional tax credits and rebates beyond federal incentives. State solar tax credits can range from a few hundred dollars to over $1,000, depending on your location. Check with your state's energy office or consult with a solar professional to determine what additional incentives are available in your area.
Battery Storage Incentives
While residential systems under 25 kW aren't eligible for SMART battery adders, adding battery storage still qualifies for the 30% federal tax credit. Batteries provide backup power during outages and can optimize time-of-use savings.
Property Tax Exemption
Massachusetts exempts the added value of solar installations from property tax assessments. Your home's value increases without increasing your annual property tax bill—protecting long-term affordability.

SMART Payments: $7,200 over 20 years ($360/year at $0.03/kWh)
Net Metering Savings: $1,500-$2,500 annually (depending on utility rates)
Combined, these incentives reduce your net cost to approximately $10,300 while generating $30,000-$50,000+ in electricity savings over 25 years. Actual savings vary based on your specific situation—request a personalized analysis for exact projections.
Yes! The federal Investment Tax Credit (ITC) and Massachusetts SMART 3.0 program are completely separate incentives. You can—and should—claim both.
The federal ITC reduces your upfront system cost by 30%, while SMART provides ongoing monthly payments for 20 years based on your system's production. These stack with net metering credits, which reduce your monthly electricity bills.
My Local Pro handles all paperwork for both programs, ensuring you capture every available dollar without navigating complex applications yourself.
SMART 3.0, launched October 2025, replaced the declining block structure used in SMART 1.0 and 2.0 with predictable flat rates adjusted annually. Previous versions caused incentive rates to drop unpredictably as capacity blocks filled—sometimes reaching near-zero values.
SMART 3.0 provides stable residential rates ($0.03/kWh standard, $0.06/kWh low-income) locked at enrollment for 20 years. Annual adjustments by the Department of Energy Resources ensure rates reflect current solar costs and equity goals while protecting ratepayers.
Note: Residential systems under 25 kW are no longer eligible for battery storage adders, but batteries still qualify for the 30% federal tax credit and provide valuable backup power.
SMART 3.0 is available to customers of three Massachusetts investor-owned utilities:
Eversource: Serving eastern and central Massachusetts
National Grid: Serving Cape Cod, central Massachusetts, and parts of Greater Boston
Unitil: Serving Fitchburg and surrounding areas
Municipal electric utilities operate separate solar incentive programs. If you're served by a municipal utility, My Local Pro can help identify applicable local programs and incentives specific to your service area.
SMART payments begin after your system is interconnected to the grid and your installer submits the final claim through the utility portal. Once approved, you receive monthly payments via direct check from your utility for 20 years.
The timeline from installation to first payment typically ranges from 2-4 months, depending on utility processing times and inspection schedules. My Local Pro coordinates all submissions and follows up with utilities to minimize delays.
Your incentive rate is locked at enrollment, so even if SMART rates adjust annually, your payment rate remains fixed for the full 20-year term.
Yes, you can add battery storage to your solar system, but residential systems under 25 kW are no longer eligible for SMART battery storage adders under SMART 3.0. However, batteries still provide significant value:
Federal Tax Credit: Batteries installed with solar qualify for the full 30% ITC, reducing battery costs substantially.
Backup Power: Batteries provide reliable power during outages, which are increasingly common in Massachusetts.
Energy Independence: Store excess solar production for nighttime use, reducing grid dependence.
Time-of-Use Optimization: If your utility offers time-of-use rates, batteries can shift energy consumption to lower-cost periods.
My Local Pro designs integrated solar + battery systems that maximize federal tax benefits while providing outage protection and energy flexibility.
SMART program benefits transfer with property ownership. When you sell your home, the new owner continues receiving the remaining SMART payments under the original enrollment terms and rate.
This transferability actually enhances your home's marketability—buyers recognize the value of locked-in SMART payments and reduced electricity costs. Solar installations typically increase home values by 3-4%, and the remaining SMART payments provide quantifiable future savings that appraisers and buyers can verify.
My Local Pro provides documentation of SMART enrollment, expected payments, and system performance history that can be shared with prospective buyers during the sales process.
The federal Investment Tax Credit remains at 30% through December 31, 2032, then steps down to 26% in 2033 and 22% in 2034. Installing before 2033 maximizes federal benefits.
SMART 3.0 rates are adjusted annually by the Massachusetts Department of Energy Resources based on solar costs, participation levels, greenhouse gas reduction goals, and ratepayer impacts. Rates could increase to support equity goals or decrease if solar costs fall significantly.
Importantly, your SMART rate is locked at enrollment for 20 years—annual adjustments only affect new enrollments. Acting now locks in current incentive levels while they're most favorable.
