Worcester is one of Massachusetts' fastest-growing solar markets, and for good reason: MA electricity rates average $0.22/kWh, the SMART program pays you for every kWh you generate for 10 years, and the federal ITC covers 30% of your system cost. Here's the complete guide.
Worcester is one of Massachusetts' fastest-growing solar markets, and the numbers explain why. Massachusetts has the highest electricity rates in the continental United States at $0.22/kWh, and Worcester homeowners are served by National Grid, which participates fully in the state's SMART incentive program. The combination of high electricity costs and the SMART program makes Worcester one of the best cities in the country for solar ROI. Note: the 30% federal tax credit expired December 31, 2025.
Why Worcester Homeowners Are Going Solar in 2026
Worcester averages 4.0 peak sun hours per day, slightly below the national average but more than enough to make solar highly profitable given Massachusetts' electricity rates. A typical 8 kW system in Worcester produces approximately 8,800 kWh per year, enough to cover most of a typical home's electricity needs.
At $0.22/kWh, that system saves you approximately $1,936 per year on electricity alone, before counting any incentives.
