The average cost to install solar on a home in Massachusetts is $4.85 per watt, with about 80 percent of systems installed for $3.41 per watt to $5.60 per watt. This is higher than the average solar cost in the New England Region of $4.62 per watt.
The average size of a solar system in Massachusetts is 7.2 kilowatts, which would cost around $34,900 without any federal, state, or local incentives.
1 kilowatt of solar PV in Massachusetts produces an average of 1,227 kilowatt-hours of electricity per year, so a 7.2 kilowatt solar system would generate 8,836 kilowatt-hours of electricity every year. An average household in Massachusetts uses 7,219 kilowatt-hours of electricity in a year.
With an average state electricity price of 19 cents per kilowatt-hour, this solar system could save a household in Massachusetts $1,720 each year. At this rate of annual savings, the system could pay for itself in about 20 years assuming no additional system expenses. This is less than the expected 30-year lifespan of a typical solar panel.
