Is solar worth it in Massachusetts?
Short answer for a typical Massachusetts home: a strong payback — roughly 6.0 years to break even after the 30% credit. Run your own bill through the calculator below.
Massachusetts gets moderate sunshine — about 4 peak sun hours a day — and residential electricity runs around $0.3/kWh. For a typical $150-a-month power bill, that points to roughly a 5.1-kW system costing about $10,788 after the 30% federal tax credit, paying for itself in about 6.0 years and netting on the order of $50,577 over 25 years. Your own numbers will differ — the calculator above uses your real bill.
Massachusetts has modest sun but very high electricity rates and the SMART incentive program, so solar pays back quickly here. It's consistently one of the better states for solar economics despite the cloudy reputation.
What changes the math in Massachusetts
- Your electricity rate — the more you pay per kWh, the more each solar kWh saves you. Massachusetts sits at about $0.3.
- Sun hours — more sun means a smaller, cheaper system covers the same usage. Massachusetts averages ~4 hours.
- Net metering / buyback — how your utility credits power you export swings the payback; check your specific utility's current terms.
- Install cost — quotes vary by installer and roof; the calculator defaults to a typical $/watt you can override.
