Choosing a Massachusetts Solar Company
Massachusetts solar projects vary by electric distribution company, roof layout, town permitting, and whether a home is in Eversource, National Grid, or Unitil territory. A good proposal should separate equipment cost, expected production, SMART 3.0 value, storage adders, tax exemptions, and any utility assumptions that still need verification.
Sunfinity Power brings one coordinated solar and roofing process to Massachusetts homeowners. That matters when roof age, structural condition, electrical work, and battery placement need to be solved before panels are installed.

Why Massachusetts Solar Math Works
Massachusetts solar economics should be modeled utility by utility. Eversource, National Grid, and Unitil customers may see different interconnection details, storage adder values, and net-metering tariff assumptions.
The verified 2026 SMART 3.0 residential Flat Incentive Rate is $0.03/kWh for 20 years for systems up to 25 kW AC, with $0.06/kWh for low-income customers. Storage adders are EDC-specific, so the battery calculation should match the homeowner's utility.
Massachusetts also provides a 100% property-tax exemption on added solar value for 20 years and a sales-tax exemption for solar equipment. Exact net-metering credit rates should be verified against the current EDC tariff before a homeowner relies on project-specific savings.
