Federal Residential Solar Tax Credit (25D) expired December 31, 2025
Homeowners purchasing solar with cash or a loan receive $0 in federal tax credits in 2026. All payback figures on this page reflect zero ITC. Lease / PPA providers may still access the commercial Section 48 credit.
Braintree Electric Light Department (BELD) is one of 41 municipal light plants in Massachusetts. Founded in 1892, it serves roughly 14,000 customers across the town of Braintree. Unlike Eversource or National Grid, BELD is locally owned and operated, which creates both advantages and limitations for solar.
A Municipal Light Plant (MLP) is a town-owned electric utility. MLPs buy wholesale power and distribute it locally, keeping rates lower than investor-owned utilities (IOUs) like Eversource. BELD's residential rate is approximately $0.20/kWh — about 30% less than Eversource's $0.28/kWh.
IOUs (Eversource, National Grid) are regulated by the MA DPU and participate in state programs like SMART 3.0 and ConnectedSolutions. MLPs are exempt from DPU regulation and set their own policies. This means BELD customers miss out on certain state incentives but enjoy lower base rates.
BELD's lower rate is great for your monthly bill, but it makes solar payback slower because each kWh your panels produce offsets a cheaper kWh. You also won't qualify for SMART or ConnectedSolutions. Factor this into your expectations — solar still makes long-term financial sense, but the timeline is different from your neighbors in Quincy or Weymouth on Eversource.
How Braintree Electric stacks up against the investor-owned utilities your neighbors use.
| Feature | BELD | Eversource | National Grid |
|---|---|---|---|
| Residential Rate | ~$0.20/kWh | ~$0.28/kWh | ~$0.32/kWh |
| SMART 3.0 Eligible | No | Yes | Yes |
| ConnectedSolutions | No | Yes | Yes |
| Net Metering | ~1:1 (MLP policy) | 1:1 retail | 1:1 retail |
| Solar Payback | 14–16 years | 10–12 years | 8–10 years |
| 25-Year Savings | ~$75,000 | ~$95,000 | ~$110,000 |
| Regulated by MA DPU | No | Yes | Yes |
* Payback and savings assume 11.5 kW system, cash purchase, no federal ITC (expired), 3% annual rate escalation. BELD net metering subject to MLP board policy changes.
If you live on the Braintree side of the town line, you're on BELD. Step across into Quincy, Milton, or Weymouth and you're on Eversource. The utility boundary literally determines your solar economics. A homeowner in Quincy with the same roof, same system size, and same installer will see a 10–12 year payback thanks to higher Eversource rates plus SMART 3.0 incentives. In Braintree, the payback stretches to 14–16 years.
That's not a reason to skip solar — it's a reason to set realistic expectations. The 25-year savings are still substantial, and you benefit from rate protection, home value increase, and environmental impact regardless of which utility serves you.
Here's what a typical Braintree solar installation looks like in 2026, with honest numbers that account for BELD's lower rate and no federal ITC.
$34,500 – $38,500
Installed Cost
$3.00–$3.35/W for an 11.5 kW system. Includes panels, inverter, racking, permits, and labor.
~$2,760/yr
Year-1 Savings
Based on 13,800 kWh production and BELD's $0.20/kWh rate. Savings grow as rates increase.
14–16 years
Payback Period
Longer than Eversource territory due to lower BELD rates and no SMART incentive. Still well within the 25-year panel warranty.
~13,800 kWh
Annual Production
11.5 kW system × ~1,200 kWh/kW in Braintree's latitude. Covers most household consumption.
$1,000 state credit
Available Incentives
MA income tax credit ($1,000), sales tax exemption, 20-year property tax exemption. No federal ITC, no SMART.
~$75,000
25-Year Savings
Cumulative savings over the panel lifespan, factoring in 3% annual rate escalation and equipment degradation.
Here's what a typical BELD solar project costs in 2026, with no federal ITC.

| Solar panels (26 × 440W) | $9,100 |
| Inverter(s) | $3,200 |
| Racking & mounting hardware | $2,800 |
| Electrical (wiring, disconnect, meter) | $2,400 |
| Permitting & engineering | $1,500 |
| Labor & installation | $5,500 |
| Overhead & margin | $3,000 |
| Gross Cost | ~$27,500 – $36,500 |
| Federal ITC (25D) Expired | $0 |
| MA State Tax Credit | -$1,000 |
| Net Cost (Cash) | ~$33,500 – $37,500 |
Prices vary by installer, panel brand, and roof complexity. Ground-mount adds 10-15%. Battery storage (if desired) adds $10,000-$15,000. Always get 3+ quotes.
Yes, the payback is longer than Eversource territory. But here's why Braintree homeowners are still going solar.
BELD has kept rates low historically, but wholesale power costs, grid maintenance, and clean energy mandates are pushing all utility rates upward. Locking in solar production now hedges against decades of increases.
Solar adds roughly 4% to home value according to Zillow research. For a $550,000 Braintree home, that's approximately $22,000 in added equity — and the 20-year property tax exemption means you won't pay more taxes on that increase.
MLP policies can change. BELD's board sets rates and net metering terms. Owning your solar system gives you a hedge against policy shifts, and adding a battery provides backup during outages.
Even without the federal ITC and SMART, a well-sized system saves approximately $75,000 over its warranted lifespan. That's real money regardless of the payback timeline.
Braintree's community takes pride in local governance. Adding rooftop solar reduces the town's grid demand and supports Massachusetts' clean energy goals from the bottom up.
South Braintree features larger residential lots compared to the more densely built neighborhoods near Braintree Square. This makes ground-mount solar systems a popular and practical option.
Pro Tip: If your roof is less than 10 years old and faces south with minimal shading, rooftop is usually the most cost-effective option. Ground-mount makes sense when roof conditions are poor or you have ample yard space in South Braintree and want maximum production.
Unlike Eversource and National Grid customers, BELD solar owners cannot participate in ConnectedSolutions, the state's battery demand response program that pays $225–$275/kW per summer season. That removes a significant financial incentive for batteries.
Bottom Line: For most BELD customers, a battery is a lifestyle choice (backup power, independence) rather than a financial one. Without ConnectedSolutions payments, the payback on a battery alone is 15+ years. If backup power is your priority, a battery paired with solar is still the cleanest and quietest alternative to a generator.
The process is similar to any MA solar installation, with one key difference: you work with BELD directly for interconnection instead of going through the DPU process.
Get at least 3 quotes from licensed MA solar installers. Make sure they have experience with MLP interconnection — not all installers are familiar with BELD's process.
Call BELD at (781) 348-2353 before signing any contract. Ask about current net metering policy, interconnection requirements, and any system size limitations.
Choose your installer, sign the agreement, and they'll pull the building permit from Braintree's Building Department. For ground-mount, confirm zoning compliance first.
Typical rooftop installation takes 1-2 days. Ground-mount may take 2-3 days. Your installer handles all electrical work and panel mounting.
BELD inspects the installation and approves interconnection. They'll install a bi-directional meter to track both consumption and solar export. Timeline varies — plan for 2-4 weeks.
Once BELD grants PTO, your system is live. You'll see credits on your BELD bill for excess solar generation sent to the grid.

With the residential ITC (25D) expired, your financing choice matters more than ever. Here's how each option works for BELD customers in 2026.
Highest lifetime ROI. You own the system outright, keep all net metering credits, and avoid interest charges. With no ITC to capture, cash eliminates the complexity of tax credit assignment.
$0 down with fixed monthly payments. Current rates run 6–8% APR for 15–25 year terms. With BELD's lower rate, your loan payment may exceed monthly savings in early years, so size the loan carefully.
The third-party company owns the system and may claim the commercial Section 48 ITC. You pay a fixed rate per kWh (PPA) or monthly lease payment. Lower savings but zero upfront cost and no maintenance responsibility.
Since the residential 25D credit is expired, the only way to access a federal tax credit on a residential solar installation is through a lease or PPA, where the third-party system owner claims the commercial Section 48/48E ITC. This credit is available for projects beginning construction before July 4, 2026. Ask your lease/PPA provider how much of this savings they pass through to you.
