About Solar in Worcester
Why Worcester Homeowners Are Going Solar in 2026
Worcester shares the same Eversource utility territory and Massachusetts incentive stack as Boston, making it a strong solar market. The SMART program, 15% state tax credit, and full sales and property tax exemptions provide meaningful incentives even without the federal ITC. Worcester's slightly lower sun hours (4.1/day) vs. Boston (4.2/day) have minimal impact on system economics.
