Net Metering in Massachusetts
Massachusetts offers full net metering — you receive full retail credit for excess solar energy sent back to the grid. This maximizes your savings and shortens your payback period.
Net metering rules are set by state/provincial regulators and utilities and can change — confirm current terms with your utility before purchasing.
Utility Landscape in Massachusetts
Instead of open-ended net metering, Massachusetts pays most new solar owners through SMART (Solar Massachusetts Renewable Target), a state program run by the Department of Energy Resources that pays a fixed per-kWh incentive on a declining block schedule — the rate offered to new applicants drops in steps as each block of capacity fills. Whether SMART or net-metering credits apply, and at what rate, depends on which of the state's two largest utilities serves you (Eversource or National Grid) and how much of your area's current block is already claimed, so the same system installed six months apart can lock in different economics.
How Solar Varies Within Massachusetts
Coastal Boston-area sites see slightly lower peak sun hours than inland western Massachusetts around the Berkshires, but the difference is modest compared to states with true desert-to-coast variation — New England's solar economics are driven far more by electricity rates and the SMART block schedule than by geography.
Worth Knowing Locally
Massachusetts' housing stock is dense with multi-family and condo buildings, so community shared solar — subscribing to a portion of an off-site solar farm's output instead of installing panels on your own roof — is a mainstream option here in a way it isn't in most single-family-home-dominated states.
What This Estimate Does Not Assume
This calculator does not automatically apply the expired US federal 30% residential tax credit, the closed Canada Greener Homes Grant or Loan, or any unconfirmed state or utility rebate for Massachusetts. If you find a currently active program, confirm it with the issuing agency — we link the general databases we trust in our methodology page.
