Is Solar Worth It in Boston, Massachusetts? (2026)

Direct answer
Boston, Massachusetts in 2026: residential electricity averages 30.1¢/kWh (EIA, 2026 YTD). Solar production for Boston is modeled at ~1300 kWh per kW per year, derived from Massachusetts's NREL PVWatts v8 state value (1302 kWh/kW) adjusted for the city's latitude — a modeled estimate, not a site-specific PVWatts run. Massachusetts uses full-retail net metering. State tax credit: 15% (cap $1,000). SREC market active at ~$30/MWh. A typical 6 kW system in Boston has an estimated payback of 6.8 years. The federal residential credit (Section 25D) expired Dec 31, 2025; state and utility incentives are the deciding factor in 2026. Sources: EIA, NREL PVWatts v8, DSIRE (retrieved 2026-08-29).

The honest answer depends on four numbers unique to Boston: your electricity rate, your solar production, your net metering policy, and your state incentives. Here are the real figures, with sources and dates. City production is a modeled estimate derived from Massachusetts's real NREL PVWatts v8 value adjusted for local latitude.

Boston FAQ

How much solar production can I expect in Boston?

PVFig models Boston at ~1300 kWh per kW installed per year, derived from Massachusetts's NREL PVWatts v8 state value (1302 kWh/kW) adjusted for the city's latitude. This is a modeled estimate — a site-specific PVWatts run with your exact roof azimuth, tilt and shading will differ. Actual output also depends on panel quality and local weather.

What is the estimated solar payback in Boston?

At a typical 3.10/W installed cost and 30.1¢/kWh electricity, a 6 kW system in Boston has an estimated payback of about 6.8 years. That is one of the faster paybacks in the country.

Does Massachusetts have net metering and a solar tax credit in 2026?

Massachusetts uses full-retail net metering. Massachusetts offers 15% (cap $1,000). The federal residential credit (Section 25D) expired Dec 31, 2025 and does not apply to 2026 installations.

Modeled estimate & disclaimer: The city production figure (~1300 kWh/kW) is modeled from Massachusetts's real NREL PVWatts v8 state value (1302 kWh/kW) adjusted for Boston's latitude — it is not a site-specific PVWatts simulation. Electricity rate (30.1¢/kWh) is the real EIA 2026 YTD state residential average; installed cost (3.10/W) is a real regional estimate. All figures are estimates from dated public sources (EIA 2026, NREL PVWatts v8, DSIRE 2026; retrieved 2026-08-29) — not a quote or financial advice. Incentive budgets close; verify current terms with your utility and a licensed installer. Federal residential ITC (Section 25D) expired Dec 31, 2025.
