MassachusettsSolar Rebates — Utility, State & Local Programs
Massachusetts solar rebates in 2026 come from the state, regulated utilities, and local programs. The federal residential credit does not apply to a system installed in 2026, so these programs do not stack with it.
State-Level Programs
Massachusetts offers a 15% state income tax credit on installed solar costs, capped at $1,000. This is technically a tax credit, not a rebate — it reduces your state income tax liability rather than paying out cash up front. Carry-forward rules typically allow unused credit to apply in future tax years.
Massachusettsalso exempts the added home value from solar from property tax assessments — a recurring benefit worth roughly $250-$400 per year for the system's lifetime.
Massachusetts additionally exempts solar equipment from sales tax at the point of purchase, removing another 4-7% from up-front equipment cost.
Utility Rebate Programs
The following utilities operate in Massachusetts and may run rebate programs at any given time. Program availability is volatile — utilities open and close incentive windows multiple times per year, often without notice. Check directly with your utility before committing to an installation timeline.
MA SREC Income
On top of rebates, the MA SREC market pays homeowners for every megawatt-hour of solar they produce. Average five-year SREC income for a typical residential system in Massachusetts: $11,200. SRECs are tradable and clearing prices vary year to year based on Renewable Portfolio Standard demand.
How Rebates Stack
For a system installed in 2026 there is no federal residential credit to reduce, so a utility rebate does not change a federal credit basis. State income tax credits, where they exist, are claimed against state tax liability. Confirm the current rebate with the utility before you sign.
