Massachusetts Solar Panel Savings Calculator

Massachusetts Solar Panel Savings Overview

Massachusetts receives an average of 4 peak sun hours per day, providing a solid foundation for residential solar energy. With electricity rates averaging 28.5¢ per kWh — well above the national average of about 16¢/kWh — solar panels offer significant savings potential. The typical Massachusetts homeowner with a 6kW system can expect to save approximately $2,680 per year.

Solar Energy Production in Massachusetts

A standard 6kW residential solar panel system in Massachusetts produces approximately 7,008 kWh per year. This accounts for a system efficiency factor of 80%, which includes panel degradation, inverter losses, and temperature effects. While 4 peak sun hours is modest compared to sunbelt states, modern high-efficiency panels can still produce meaningful energy savings in Massachusetts.

Massachusetts Electricity Rates and Solar Context

The average residential electricity rate in Massachusetts is 28.5¢ per kWh according to EIA data. This is significantly above the national average, which means solar panels pay for themselves faster in Massachusetts. Every kilowatt-hour your panels produce replaces expensive grid electricity, amplifying your savings. With utility rates increasing annually, your solar savings grow each year.

Massachusetts Solar Incentive Programs

SMART program (performance-based incentive). SRECs. State tax credit ($1,000). Sales tax exemption. Federal 30% ITC. All Massachusetts residents are eligible for the federal 30% Investment Tax Credit (ITC), which reduces the cost of a solar system by 30% of the total installed price. Massachusetts also offers full retail net metering, allowing homeowners to earn credits for excess solar energy sent back to the grid.

Net Metering in Massachusetts

Massachusetts has full retail net metering, which is a significant financial benefit for solar homeowners. Under full retail net metering, you receive credit at the full retail electricity rate for every kilowatt-hour of excess solar energy you export to the grid. This is the most favorable policy for solar homeowners.

Best Cities for Solar in Massachusetts

The best cities for solar panels in Massachusetts include Boston, Worcester, Springfield, Cambridge, Lowell. Solar production can vary by location within the state due to differences in cloud cover, local shading, and microclimates. Southern-facing roofs with minimal shading produce the most energy. Homeowners in Boston and Worcester can typically expect production close to the state average of 4 peak sun hours per day.

How Massachusetts Compares to Neighboring States

Compared to neighboring states, Massachusetts (28.5¢/kWh, 4 sun hours) has comparable sun exposure and has higher electricity rates, making solar more attractive. See how solar savings compare in Connecticut, Rhode Island, and New Hampshire.
