Net metering & export credits
Near-retail net metering with utility caps + SMART production incentive. Massachusetts net metering credits exports near retail for residential systems. The SMART 3.0 incentive pays per-kWh production bonuses — for solar-only systems the 2025 true incentive fell to $0/kWh in Eversource MA territory, while battery-storage adders remain valuable (~$0.049/kWh).
Electricity rates
MA residential average ~30¢/kWh (EIA 2026) — among the highest in the US.
What this means for solar
- Eversource also serves Connecticut and New Hampshire under separate state rules.
- A MA state income tax credit (up to $1,000) and sales-tax exemption reduce upfront cost.
