How much you get

Per-kWh incentive — Massachusetts doesn't pay a flat rebate for solar — instead SMART 3.0 locks in a per-kWh production payment for 10 to 20 years once you're enrolled, on top of whatever you save on your own electricity bill.

Common questions

Does Massachusetts have a solar rebate for Cambridge homeowners?

Not a flat rebate — SMART 3.0 pays a locked-in per-kWh production payment for 10 to 20 years once you're enrolled, on top of your own electricity savings.

Is solar worth it in Cambridge?

Massachusetts gets decent sun for solar, and SMART 3.0's guaranteed per-kWh payment makes the economics more predictable than states relying on a one-time rebate alone.
