South Shore community with ~39,000 residents served by BELD municipal electric at ~$0.20/kWh. Braintree does NOT qualify for SMART 3.0 or ConnectedSolutions -- the solar math is different here. Payback is 10-13 years instead of 7-8.5 in Eversource towns, but solar is still profitable long-term.

Braintree Has Municipal Electric (BELD)
Braintree is served by BELD (Braintree Electric Light Department), not Eversource. This means: No SMART 3.0 income, no ConnectedSolutions battery revenue, and a lower electric rate (~$0.20/kWh vs. Eversource $0.2836/kWh). Solar is still profitable in Braintree but with a longer payback period. All calculations below reflect BELD rates and Braintree-specific conditions.
An 11.5 kW solar system in Braintree costs $34,500-$38,525 in 2026. With BELD municipal electric at $0.2/kWh (no SMART 3.0, no ConnectedSolutions), the investment pays for itself in 10-13 years and generates ~$75,000 in savings over 25 years.

Braintree is a South Shore community of ~39,000 residents located between Quincy and Weymouth. One of only ~40 municipalities in Massachusetts with its own electric utility (BELD), Braintree residents enjoy lower electric rates but miss out on state solar programs designed for investor-owned utilities.

Braintree's municipal electric creates a fundamentally different solar economics picture than neighboring Eversource towns.
| Factor | Braintree (BELD) | Quincy / Weymouth (Eversource) |
|---|---|---|
| Electric Rate | ~$0.20/kWh | $0.2836/kWh |
| SMART 3.0 Income | NOT AVAILABLE | $0.03/kWh for 20 years |
| ConnectedSolutions | NOT AVAILABLE | $275/kW summer + $50/kW winter |
| Net Metering | BELD terms (contact BELD) | 1:1 retail rate |
| Annual Savings (11.5 kW) | ~$2,760/yr | ~$3,914 + $414 SMART = $4,328/yr |
| Payback Period | 10-13 years | 7-8.5 years |
| 25-Year Savings | ~$75,000 | ~$120,000-130,000 |
Bottom line: Solar in Braintree generates roughly 40-45% less annual value than in nearby Eversource towns due to the lower rate and missing SMART/ConnectedSolutions programs. The payback is longer (10-13 years vs. 7-8.5), but solar remains a profitable investment over 25 years. Braintree homeowners benefit from the same state tax credit, property tax exemption, and sales tax exemption as everyone else.
Costs for different system sizes in Braintree at $3.00-3.35/W. Note: SMART 3.0 column replaced with net metering savings at BELD rate ($0.20/kWh).

Section 25D (the 30% residential solar tax credit) expired December 31, 2025 under the OBBBA. Braintree homeowners buying cash or loan receive $0 in federal credit. Third-party system owners (PPA/lease) can still claim Section 48/48E ITC -- but PPA rates need to be well below BELD rate ($0.20/kWh) to make sense.
Read: What happened to the solar tax creditFinancing works differently in BELD territory because annual savings are lower. Cash purchase has the best ROI. Loans require careful analysis since monthly payments may be close to savings. PPAs must offer rates well below BELD's $0.20/kWh.

Solar panels in Braintree cost $3.00-3.35 per watt installed in 2026. A typical 11.5 kW system costs $34,500-$38,525 before MA state incentives. The federal Section 25D residential tax credit expired December 31, 2025 -- homeowners receive $0 in federal credit. Braintree has municipal electric (BELD), which means SMART 3.0 and ConnectedSolutions are NOT available, resulting in a longer payback than Eversource towns.
Braintree is served by BELD (Braintree Electric Light Department), a municipal utility. This means: (1) Lower electric rate (~$0.20/kWh vs. Eversource $0.2836/kWh), which reduces annual savings. (2) No SMART 3.0 income (SMART only applies to investor-owned utilities). (3) No ConnectedSolutions battery income (Eversource program only). (4) Net metering policies are set by BELD, not the state DPU. This results in a 10-13 year payback vs. 7-8.5 years in Eversource towns.
Yes, BELD does offer a net metering arrangement for residential solar, but the terms differ from Eversource. BELD credits solar production at approximately their retail rate. Contact BELD directly at (781) 348-2353 for the latest net metering terms and interconnection requirements before committing to a solar installation.
Solar can still be worthwhile in Braintree, but the math is different. The lower BELD rate ($0.20/kWh vs. $0.2836/kWh Eversource) means less annual savings from net metering. Without SMART 3.0 income (~$400/yr lost) and ConnectedSolutions (~$3,250/yr lost for battery owners), the payback is 10-13 years instead of 7-8.5. However, the $1,000 state tax credit, property tax exemption (~$393/yr), and sales tax exemption still apply. Over 25 years, a typical system saves ~$75,000.
It depends. If you are in BELD territory, community solar subscriptions typically work through Eversource. Some community solar providers may not serve BELD customers. Check with your community solar provider whether they can credit your BELD bill. For BELD customers, rooftop solar with net metering directly from BELD is often the more straightforward path.
We understand BELD territory. We will show you exactly what solar costs and saves with BELD municipal rates -- no inflated projections based on Eversource rates or unavailable SMART/ConnectedSolutions programs.
