Are Solar Panels Worth It in Massachusetts?

Last updated July 1, 2026 · based on Massachusetts energy prices

Short answer: A typical 7 kW solar system in Massachusetts produces about 9,100 kWh/year, saves roughly $1,775/year, and pays for itself in about 11.8 years in 2026 — with no federal tax credit, which expired December 31, 2025.

In Massachusetts, where residential electricity averages about 30¢/kWh and rooftop solar yields roughly 1,300 kWh per kW per year, solar is a reasonable long-term investment, paying back in about 11.8 years.

Figures use Massachusetts average prices, a 7 kW system at $3.00/watt, 50% self-consumption at retail plus a conservative 9¢/kWh net-metering credit, and ~0.5%/yr panel degradation. Sources: EIA electricity prices and NREL PVWatts production modeling.

What this means for Massachusetts homeowners in 2026

The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025, so a 2026 installation in Massachusetts carries the full upfront cost unless a state or utility incentive applies. Because Massachusetts electricity costs well above the national average, the payback case is favorable for most well-suited roofs.
