Massachusetts Solar 2026: SMART Payments, 15% Credit & Payback
Massachusetts pays SMART performance incentives for 20 years plus a 15% state credit. See why MA still has one of the fastest solar paybacks despite high install costs.
SMART payments add real income
The Massachusetts SMART program pays a per-kWh performance incentive for 20 years (~$0.03/kWh, ~$0.06 for income-eligible). On a typical 7 kW system producing ~9,100 kWh/year, that adds roughly $270–$550/year on top of bill savings.
State credit and exemptions
Massachusetts also offers a 15% state income tax credit (cap $1,000), sales tax exemption, and 20-year property tax exemption. Electricity at ~30.2¢/kWh is among the highest in the nation, so every kWh you produce offsets a lot.
2026 payback estimate
Despite ~$3.10/W install costs, a typical MA system pays back in 7–8 years — among the fastest in the US. High rates + SMART + tax breaks more than offset the price premium. Run the ROI calculator for your exact system.
