Commercial Solar in Massachusetts in 2026
Massachusetts Eversource and National Grid commercial rates consistently rank among the highest in the US, regularly exceeding $0.22/kWh blended. The SMART program (Solar Massachusetts Renewable Target) pays 20-year production-based incentive contracts for commercial solar — adding $15,000-30,000 annually for a 300-500 kW system. Combined with the federal ITC and the state's 6.25% sales tax exemption, Massachusetts commercial solar delivers outstanding ROI. Our EPC partners are active in the Boston metro, Worcester, Springfield, and the Route 128 technology corridor.
