What renewable energy incentives are available in RI, MA, and CT in 2026?
Renewable energy incentives for homeowners in Rhode Island, Massachusetts, and Connecticut are delivered through state and utility-level programs. Massachusetts runs SMART (Solar Massachusetts Renewable Target), which pays per-kWh tariff incentives through Eversource and National Grid for residential solar systems. Rhode Island offers the Renewable Energy Growth (REG) program, a performance-based incentive administered through RI Energy, alongside net metering at the retail rate. Connecticut homeowners access the Residential Solar Investment Program (RSIP) and low-interest financing from the Connecticut Green Bank, plus net metering through Eversource and United Illuminating. Each state also exempts qualified residential solar equipment from sales tax, and Massachusetts and Rhode Island exempt the added home value from property-tax reassessment. Sunfinity Power handles SMART, REG, RSIP, and Green Bank enrollment as part of installation across RI, MA, and CT.
What is the SMART program in Massachusetts and how does it pay homeowners?
The Solar Massachusetts Renewable Target (SMART) program is administered by the Massachusetts Department of Energy Resources (DOER) and delivered through the state’s investor-owned utilities — Eversource, National Grid, and Unitil. For a residential homeowner, SMART works as a fixed per-kWh tariff payment for every kilowatt-hour the solar system produces, paid out for 10 years from the system’s interconnection date.
The incentive value declines in capacity blocks as the program fills. Earlier blocks paid higher rates; current 2026 blocks pay incrementally less but remain financially meaningful. Massachusetts homeowners also stack SMART payments with retail-rate net metering and Mass Save rebates for paired electrification work like heat pumps.
SMART eligibility requires interconnection through one of the participating utilities. Sunfinity Power handles the SMART enrollment paperwork, the interconnection application, and the tariff election as part of any Massachusetts installation.
How does Rhode Island's Renewable Energy Growth (REG) program work?
The Renewable Energy Growth (REG) program is Rhode Island’s performance-based incentive for residential solar, administered through RI Energy (formerly National Grid Rhode Island) under the Rhode Island Public Utilities Commission (RIPUC).
REG works like SMART in structure: homeowners receive a fixed per-kWh tariff payment for the energy their solar system produces, for a contracted term. The all-in REG payment is designed to make the residential solar investment financially viable without the homeowner needing to consume the energy they generate — REG-enrolled systems sell production back at the REG tariff rate rather than offsetting the utility bill directly.
Rhode Island homeowners typically choose between REG enrollment and Rhode Island’s net-metering tariff during the application phase. Sunfinity Power runs the financial comparison for each home as part of the savings analysis.
What incentives does Connecticut offer through the Green Bank and RSIP?
Connecticut’s incentive landscape runs through the Connecticut Green Bank — a quasi-public entity created in 2011 and a national model for state green banks. For residential solar, Green Bank delivers three primary programs:
Residential Solar Investment Program (RSIP)— performance-based incentive payments for qualified residential solar systems interconnected through Eversource or United Illuminating.
Smart-E loans — low-interest unsecured financing for solar and other home energy improvements, originated through participating Connecticut credit unions and banks.
CPACE financing — for larger energy projects that include solar, secured against the property via a tax assessment.
Connecticut also offers net metering through Eversource and United Illuminating, sales-tax exemption on residential solar equipment, and a property-tax exemption for the added home value. Sunfinity Power services Connecticut homeowners and coordinates with Green Bank-approved financing partners during the financing approval phase.
How does net metering work in RI, MA, and CT?
Net metering is the billing arrangement that lets a homeowner’s solar system feed excess electricity back to the grid in exchange for utility-bill credits.
Rhode Island: Net metering is administered through RI Energy at a retail-equivalent rate. Net metering and the REG program are alternatives, not stackable for the same kWh of production.
Massachusetts: Net metering is offered through Eversource, National Grid, and Unitil at the utility’s full retail rate. Massachusetts homeowners can stack net metering with SMART tariff payments — the two are designed to work together.
Connecticut: Net metering is offered through Eversource and United Illuminating, with monthly true-up and annual credit reconciliation.
The state-by-state mechanics matter for system sizing. Sunfinity Power sizes Rhode Island, Massachusetts, and Connecticut systems against each state’s net-metering and tariff rules — not a one-size-fits-all template.
What sales-tax and property-tax exemptions apply to residential solar?
All three states exempt qualified residential solar equipment from state sales tax — homeowners do not pay sales tax on panels, inverters, racking, or battery storage purchased as part of a solar installation.
For property tax:
Massachusetts exempts the added assessed value of a residential solar system from local property-tax reassessment for 20 years from installation (M.G.L. Chapter 59, Section 5, Clause 45).
Rhode Island exempts residential renewable energy systems from property-tax assessment increases.
Connecticut exempts the added value of qualifying renewable energy systems from real-property reassessment under state statute.
The practical effect: a homeowner whose property gains tens of thousands of dollars in assessed value from a solar installation does not see their local property-tax bill rise as a result.
Did the federal solar tax credit (ITC) end?
The federal Residential Clean Energy Credit (Internal Revenue Code §25D) expired at the end of 2025 and no longer applies to residential solar installations placed in service in 2026 or later. Homeowners now rely on state and utility-level programs, which remain robust across Rhode Island, Massachusetts, and Connecticut. The state programs above — SMART, REG, RSIP, Green Bank financing, net metering, and the sales/property-tax exemptions are the active incentive landscape going forward.

Frequently asked questions
Can I stack the SMART program with Massachusetts net metering?
Yes. SMART tariff payments and net metering are designed to work together for Massachusetts residential systems. Eligible production earns the SMART per-kWh tariff, and net metering offsets your retail utility purchases at retail rate.
Can I switch from net metering to REG in Rhode Island after installing?
Rhode Island homeowners typically elect REG or net metering during the interconnection application phase. Switching after enrollment is constrained by program rules — Sunfinity Power models both scenarios before installation so the choice is informed.
Are battery storage systems eligible for state incentives?
Battery storage is treated differently by each state. Connecticut Green Bank financing covers paired storage. Massachusetts SMART offers a storage adder for qualifying systems. Rhode Island’s incentive focus is the solar PV system itself. Sunfinity Power scopes the battery decision against each state’s specific rules.
How long does the incentive paperwork take?
Interconnection and tariff enrollment typically run in parallel with permitting, between four and ten weeks depending on the utility and the municipality. Sunfinity Power handles all filings.
Do I need to be a homeowner to qualify?
Yes — all state-level residential solar programs require property ownership. Sunfinity Power also expects the homeowner to plan to remain in the property for at least the duration of the financing term for the financials to make sense.
Are there income limits for these programs?
The headline incentives — SMART, REG, RSIP — are not income-restricted. Some adjacent low-income solar programs in each state are. Sunfinity Power’s financial model surfaces any additional program a homeowner may qualify for.
What documentation do I need to apply?
The standard package: 12 months of utility bills, proof of homeownership, roof age and condition, and (for financing) standard credit documentation. Sunfinity Power’s Solar Discovery Call walks through the full list.
