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.

The SolarEdge Safe Harbor: Massachusetts ITC Access Through 2030

The federal construction-start safe harbor deadline (July 4, 2026) has passed, and most developers are now racing to place projects in service by December 31, 2027 — the standard cutoff — or risk losing the ITC entirely. Our select installer network isn't on that clock. Through a pre-negotiated, physically verified equipment reservation with SolarEdge, our partners secured safe-harbored access to the federal Investment Tax Credit for qualifying Massachusetts projects completed by December 31, 2030 — a three-year extension unavailable to developers outside this network.

Deloitte independently reviewed the strategy: its team toured SolarEdge's manufacturing facility, met with SolarEdge leadership in Tampa, FL, and issued a memo confirming that projects built on this reserved-inverter methodology qualify for ITC treatment. SolarEdge has committed gigawatt-scale production capacity to this arrangement, with roughly 200 MW currently allocated to partner networks nationwide. Fewer than 10 installer networks in the US hold a direct reservation of this kind.
