Solar Panel Costs and Savings in Massachusetts (2026 Guide)
Massachusetts pairs some of the highest electricity rates in the country with one of the most structured state solar incentive programs, making it a strong solar market despite meaningfully fewer sun hours than sunbelt states.
High electricity rates drive strong savings
Massachusetts has among the highest average electricity rates of the 15 states in our state guides, similar to New York — each kWh your system offsets is worth more here than in most other states, which helps counterbalance the state’s more modest average sun hours. Run your own numbers with our calculator.
The SMART program
SMART (Solar Massachusetts Renewable Target) is the state’s primary solar incentive program, providing homeowners with per-kWh production-based payments for a set period after installation, structured differently from the SREC-style certificate markets used in states like New Jersey or Maryland. Rates under SMART are organized into declining blocks that adjust as capacity fills, so the specific rate available to you depends on timing and location — confirm current details through the Massachusetts Department of Energy Resources or a local installer.
State tax credit
Massachusetts has historically also offered its own state income tax credit for residential solar, in addition to the federal tax credit, though generally with a more modest cap than the value SMART payments can add over time — confirm the current specific amount with the Massachusetts Department of Revenue.
Winter and snow are real factors here
Massachusetts has a genuine winter season with shorter days and real snow accumulation — see our winter and snow guide for how properly sized systems already account for this seasonal pattern rather than treating it as a dealbreaker.
A mature, competitive installer market
Massachusetts has a well-established solar installer market, giving homeowners real options when comparing quotes — still worth getting multiple bids and verifying licensing and track record directly.
Bottom line
Massachusetts combines some of the highest electricity rates in the country with the SMART program’s ongoing production payments and its own state tax credit, producing a strong overall solar financial case despite more modest sun hours than sunbelt states.

Frequently Asked Questions
- What is the SMART program in Massachusetts?
- SMART (Solar Massachusetts Renewable Target) is the state's main solar incentive program, providing set payments to homeowners and businesses for the solar electricity their systems produce, structured differently from an SREC market — confirm current rates and availability through the Massachusetts Department of Energy Resources or a local installer, since program blocks and rates adjust over time.
- Does Massachusetts have a state solar tax credit?
- Yes — Massachusetts has historically offered its own state income tax credit for residential solar installations, in addition to the federal tax credit, though with a relatively modest cap compared to the SMART program's overall value — confirm the current specific credit amount with the Massachusetts Department of Revenue.
- Is Massachusetts a good state for solar despite its northern location and fewer sun hours?
- Yes, generally — Massachusetts has among the highest electricity rates in the country, and the SMART program adds ongoing production-based payments on top of bill savings, both of which help offset the state's more modest sun-hour totals compared to sunbelt states.
