Section 25D (the 30% residential solar tax credit) expired December 31, 2025 under the OBBBA. Newton homeowners buying cash or loan receive $0 in federal credit. However, third-party system owners (PPA/lease) can still claim the commercial Section 48/48E ITC -- which translates to lower PPA rates for you.

Newton has one of the most ambitious climate plans among suburban MA cities, with strong institutional support for residential solar adoption.
Newton Climate Action Plan targeting carbon neutrality
Dedicated Sustainability Director leading city initiatives
Green Newton community organization promoting renewables
Community Choice Electricity aggregation for competitive green rates
Highest EV adoption rates in MA -- driving solar+EV demand
Streamlined solar permitting for residential properties
Newton's strong environmental policy, high property values, and educated homeowner base create an ideal market for solar. The city actively removes barriers to adoption, and neighborhood-level enthusiasm (especially in Newton Centre, Newtonville, and Newton Highlands) drives strong word-of-mouth referrals.
How Newton solar costs compare to neighboring communities. All are in Eversource territory with access to the same state incentives.
| City/Town | Cost/W | Avg System | Utility | Notes |
|---|---|---|---|---|
| Newton | $3.10-3.45 | 11.5 kW | Eversource | 13 villages, diverse housing, high EV adoption |
| Wellesley | $3.15-3.50 | 12 kW | Eversource | Similar affluent suburb, large homes |
| Brookline | $3.15-3.55 | 9 kW | Eversource | Denser, more multi-family, some historic |
| Waltham | $3.05-3.40 | 10.5 kW | Eversource | More affordable homes, strong solar market |
| Cambridge | $3.15-3.50 | 9 kW | Eversource | Dense academic city, historic overlays |
Solar panels in Newton cost $3.10-3.45 per watt installed in 2026. A typical 11.5 kW system costs $35,650-$39,675 before MA state incentives. The federal Section 25D residential tax credit expired December 31, 2025 -- homeowners receive $0 in federal credit. Massachusetts state incentives (SMART 3.0, net metering, state tax credit, and tax exemptions) still make solar highly profitable in Newton.
Newton is divided into 13 villages, each with different housing styles and solar conditions. Villages like Newtonville, West Newton, and Newton Highlands have excellent solar access with newer construction and fewer tree canopy issues. Chestnut Hill and Waban have larger homes (ideal for bigger systems) but more mature trees. Newton Upper/Lower Falls have some historic character that may require consideration. In all cases, your installer will do a site assessment to evaluate your specific roof.
SMART 3.0 (Solar Massachusetts Renewable Target) pays solar system owners $0.03/kWh for all electricity produced, locked in for 20 years. An 11.5 kW system in Newton generates approximately $414/year in SMART income, totaling roughly $7,850 over the program duration. Low-income households qualify for $0.06/kWh (double rate). Battery storage adds $0.04/kWh on top.
ConnectedSolutions is Eversource's demand response program for battery owners. During peak grid events (primarily summer), you discharge your battery to the grid and earn $275/kW in summer and $50/kW in winter. A typical 10 kW home battery can earn $2,750 in summer plus $500 in winter, totaling $3,250/year. Newton is in Eversource territory, which offers the highest ConnectedSolutions rates in MA.
Newton has a comprehensive Climate Action Plan targeting carbon neutrality. The city actively promotes solar energy through streamlined permitting, community outreach, and sustainability initiatives. Newton's Green Newton program and the city's Sustainability Director work to reduce barriers to solar adoption. The city also participates in community choice electricity aggregation.
Yes. Newton actually has a slightly faster payback than many nearby towns (7-8.5 years) because of its high Eversource electricity rate ($0.2836/kWh), SMART 3.0 income, and MA state incentives. With Newton's $1.1M+ median home values, the 20-year property tax exemption is extremely valuable -- saving ~$429/year. Over 25 years, a typical system saves approximately $130,000.
Yes, but it depends on your ownership structure. Newton has many condo conversions and multi-family buildings. Condo associations can vote to install solar on shared roof space, with costs and benefits split among unit owners. For buildings where rooftop solar is not feasible, community solar is an excellent alternative -- you subscribe to a local solar farm and receive 10-20% bill savings with no installation required.
Newton is known as the "Garden City" and has significant mature tree canopy in many neighborhoods, especially Waban, Newton Centre, and Chestnut Hill. Modern solar design tools use satellite imagery and LIDAR data to map shading patterns precisely. In some cases, selective tree trimming can significantly improve solar access. Even with partial shading, microinverters or power optimizers allow panels to perform independently, so shaded panels do not drag down the entire array.
We will assess your specific roof, village conditions, tree canopy, and Eversource rate to show you exactly what solar costs and saves for your Newton home -- including SMART 3.0 and ConnectedSolutions.
