Massachusetts Solar Rebates & Incentives
Massachusetts has one of the most generous solar incentive stacks in the country, but the programs are layered and confusing on purpose. Here's what a MA homeowner should actually expect in 2026 — including the electrical scope most solar salespeople gloss over.
What's inside
- The 4 incentives that stack: federal ITC, SMART, net metering, and battery adders
- How SMART payments actually work (10-year fixed monthly payments, not a lump sum)
- Net metering 2.0: what a kWh sent to the grid is really worth to you
- Battery incentives: ConnectedSolutions ($225–$275/kW/summer) and SMART battery adders
- Realistic installed prices per watt for MA in 2026
- The electrical work included in a solar install (and what should be a separate line item)
- Warning: the leased-solar / PPA math almost never works in MA
