Why switch to Solar in Massachusetts?
Serving homeowners across Massachusetts with solar and battery installations designed for Eversource and National Grid customers
Save Money
Massachusettss homeowners pay some of the highest electricity rates in the country - up to 33¢/kWh and rising. Going solar locks in a lower rate and protects you from utility price increases for decades.
Pair Solar with Batteries
Add battery storage to keep the lights on through New England storms and outages. Massachusetts' ConnectedSolutions program even pays you to make your battery available during peak demand events.
Help the Environment
Every kilowatt-hour of solar you produce displaces fossil-fuel generation. Massachusetts homeowners who go solar make a meaningful, lasting contribution to a cleaner grid and a healthier planet.
Perfect for Massachusetts
Despite the cold winters, Massachusetts gets ample sunlight for strong solar production. Favorable roof pitches and the state's robust incentive stack make MA one of the top solar markets in the US.
