Massachusetts State Incentives
SMART program; income tax credit (15%, up to $1,000)
Net Metering: Eversource
JouleIO's planning data marks net metering or a solar export credit as available for Eversource customers in New Bedford. Export credits can be at retail or below-retail rates depending on the current tariff, so confirm terms with the utility that serves your address.

Solar Energy in New Bedford, Massachusetts
New Bedford, Massachusetts receives an average of 3.8 peak sun hours per day, offering adequate solar resources for homeowners looking to reduce their electricity bills. With a planning electricity rate of 23.4¢ per kWh (EIA Massachusetts residential average for 2026-06: 29.61¢; U.S. average 18.34¢), above the national average, solar savings potential is stronger.
A typical 6kW solar system in New Bedford produces approximately 6,658 kWh per year, saving homeowners an estimated $1,560 annually. The system pays for itself in about 12.7 years, after which you enjoy essentially free electricity for the remaining 12+ years of the system's warranty life.
JouleIO's dataset carries a modeled solar-adoption value of 7.6% for New Bedford. It is a rough planning placeholder, not a measured count of local installations, so use utility interconnection data or installer quotes if local adoption matters to your decision.

Methodology & Solar Data Sources for New Bedford
How we calculate New Bedford solar potential and savings: Annual production = system kW × estimated peak sun hours × 365 × 0.80 system derate × a roof-orientation factor. This is a simplified planning formula, not a PVWatts run for your address. Cost uses a planning price per watt for Massachusetts, and bill savings use a planning electricity rate of 23.4¢/kWh (the EIA Massachusetts residential average for 2026-06 is 29.61¢/kWh).
- Peak sun hours for New Bedford (3.8/day) are a planning estimate in the typical range for Massachusetts, not a site-specific NREL NSRDB value. Enter your address in NREL PVWatts for a location-specific production estimate.
- System sizing defaults to a 6kW residential rooftop system with roughly 400W panels; adjust the size and monthly bill to match your home.
- Federal tax credit: modeled as 0% for 2026 residential installations because IRS guidance says the Residential Clean Energy Credit is not available for property placed in service after December 31, 2025.
- Exports are discounted rather than credited 1:1 at retail, because many utilities have shifted to net billing or avoided-cost export rates. Verify your utility's current tariff.
- 25-year savings assume a 2.5% annual electricity-rate increase and do not subtract panel degradation, inverter replacement, or maintenance.
