- Massachusetts power is among the priciest in the country, which is what makes solar pay. Residential electricity averages about 30.21 cents per kWh (EIA, as of March 2026), nearly double the national average, so every kilowatt-hour your roof makes offsets an expensive one from National Grid.
- Your utility is National Grid, not Eversource. Woburn sits in National Grid’s Massachusetts electric territory, so your net metering and interconnection run through National Grid, not the Eversource system that serves Boston (National Grid MA tariff MDPU 1625, as of March 2026).
- National Grid credits a home solar system near full retail, not wholesale. Power you use on the spot offsets the full retail rate, and net excess earns the Standard Net Metering Credit, valued near the retail rate for a residential system of 25 kW AC or less (National Grid MDPU 1625; Mass.gov DPU, as of 2026).
- SMART pays you on top, at a flat 3 cents per kWh for 20 years. Under the SMART 3.0 redesign the state approved in May 2026, a residential system 25 kW AC or smaller earns the system owner about $0.03 per kWh generated for 20 years, the same on a National Grid account as on any MA utility (Mass.gov SMART 3.0, as of 2026).
- Massachusetts also waives sales and property tax and gives a state income-tax credit. A 15% state income-tax credit up to $1,000 (M.G.L. c.62 s.6), a 100% sales-tax exemption (M.G.L. c.64H s.6), and a 20-year property-tax exemption (M.G.L. c.59 s.5), all as of 2026.
- The 30% federal homeowner credit (Section 25D) ended after December 31, 2025 (IRS, as of January 1, 2026), so a Woburn homeowner who buys solar in 2026 cannot claim it. The Massachusetts programs were not affected.
Solar panels in Woburn, MA pay off for the same reason they do across Greater Boston, you are replacing some of the most expensive electricity in the country, but the local details here are not Boston’s. Woburn is National Grid territory, not Eversource, so your net metering runs on National Grid’s tariff. Your roof is most likely a single-family suburban one, which means no Boston Landmarks review and a simpler install, with one Woburn-specific permit step. This guide covers what solar really costs and earns in Woburn (Middlesex County), how National Grid credits the power you send back, the Massachusetts SMART and tax incentives you may qualify for in 2026, and the federal-credit change to plan around, then you can check your address in about a minute. Updated for 2026.
What a Woburn solar roof actually earns (2026)
Is solar worth it in Woburn in 2026? For most owner-occupied single-family homes with decent sun, yes, and here is the math.
Why Woburn’s high electric rates make solar pay
The reason solar works in Woburn is the price of the National Grid power it replaces. Massachusetts residential electricity averages about 30.21 cents per kWh (EIA, as of March 2026), one of the highest rates in the nation, and National Grid’s bundled residential rate tracks that statewide figure. Every kilowatt-hour your roof produces and you use offsets one you would otherwise buy at that rate. As a quick original benchmark, at 30.21 cents per kWh each 1,000 kWh your system generates and you use is worth about $302 a year (30.21 cents times 1,000 kWh), so a system that covers most of a typical home’s usage replaces a large annual electric spend. For the exact cents on your own bill, read the supply and delivery lines on your National Grid statement.
Your production is what turns that high rate into savings, so size it to your own roof. Woburn gets a solar resource typical of eastern Massachusetts, and a well-placed suburban roof offsets a large share of a normal home’s annual use. Because output depends on your roof’s pitch, shading, and orientation, estimate your specific roof with NREL’s free PVWatts calculator rather than a generic number. Your production drives both your net-metering credits and your SMART payments, so it is worth getting right. To weigh the long-run numbers, see the financial case for whether solar panels are worth it and how solar lowers your electricity bill.

|---|---|---|
| Massachusetts residential electricity rate | About 30.21 cents per kWh | EIA, as of March 2026 |

How National Grid net metering credits a Woburn solar home
National Grid rewards your solar in two ways, and the first one is the bigger. Every kilowatt-hour your panels make that you use on the spot is simply a kilowatt-hour you do not buy, so it offsets power at the full retail rate, about 30 cents. When your roof makes more than you are using, that net excess flows to the grid and National Grid credits it under its Massachusetts tariff at the Standard Net Metering Credit, valued at the sum of the utility’s per-kWh basic service, distribution, transmission, and transition charges, which lands near the retail rate for a residential solar system (National Grid MDPU 1625, as of March 2026). It leaves out a few surcharges, so it is near-retail rather than the full bundled rate, and those dollar credits carry forward from one billing period to the next. For the mechanics in plain terms, see how net metering credits your solar exports and the National Grid net metering and rate plan in Massachusetts guide.
Note: A common myth online is that Massachusetts only pays a wholesale price for solar exports. For a home system, that is not what National Grid’s current tariff says. Small residential solar earns the near-retail Standard Net Metering Credit, and because Massachusetts raised the cap-exempt threshold to 25 kW AC, a normal home system is cap-exempt and keeps that credit (National Grid MDPU 1625; Mass.gov DPU, as of 2026). A solar system only shifts to a reduced market credit after 25 years, and only if it is not cap-exempt, so a typical Woburn home is not affected.
| What happens to your solar power | How it is valued | Notes |
|---|---|---|
| Power you use the moment you make it | Full retail rate (about 30 cents per kWh) | The largest source of savings |
| Net excess you export to the grid | Standard Net Metering Credit, near the retail rate | Credits carry forward billing period to billing period |
| SMART payments | A separate flat per-kWh incentive, paid for 20 years | On top of the bill credits, to the system owner |
SMART 3.0 on a National Grid account
On top of net metering, Massachusetts pays the system owner a per-kWh incentive through the SMART program. Under the SMART 3.0 redesign the Department of Public Utilities approved on May 19, 2026, a residential system of 25 kW AC or less earns a flat incentive of about $0.03 per kWh generated, for a 20-year term, paid to whoever owns the system (Mass.gov SMART 3.0, as of 2026). The residential rate is set statewide, so it is the same on a National Grid account in Woburn as on any Massachusetts utility, and a system under 25 kW is exempt from the program’s capacity cap, so you can enroll even if National Grid’s block is full.
If you pair a battery, there is an added storage value, but it is not a simple flat number. SMART 3.0 adds an energy storage value when you install qualifying battery storage with your solar, calculated through a formula based on the battery’s size and duration rather than a fixed per-kWh figure (Mass.gov SMART 3.0, as of 2026). Because the storage value varies with your equipment, ask your installer for the current number for your specific system rather than budgeting around a flat estimate. On a lease or PPA the SMART payment goes to the company that owns the panels, not to you.
Massachusetts solar incentives beyond net metering
Beyond net metering and SMART, Massachusetts stacks three tax benefits that go to the system owner. On a cash or loan purchase that owner is you; on a lease or PPA it is the company that owns the panels. The statewide detail lives on our Massachusetts solar guide; here is what each one is and where to confirm it.
- A state income-tax credit (Schedule EC). Massachusetts gives a Residential Energy Credit worth 15% of the net cost of a solar system, capped at $1,000 for your principal residence, with any unused amount carried forward for up to three years (M.G.L. c.62 s.6, as of 2026).
- A 100% sales-tax exemption. Qualifying solar equipment for your principal residence is exempt from the state’s 6.25% sales tax, so you pay no Massachusetts sales tax on the system (M.G.L. c.64H s.6, as of 2026).
- A 20-year property-tax exemption (Clause 45). The added home value from a qualifying solar system is exempt from local property tax for 20 years, as long as the system is sized to no more than 125% of your home’s annual electricity needs (M.G.L. c.59 s.5, as of 2026).
| Massachusetts solar benefit | What it is | Status in 2026 |
|---|---|---|
| Net metering (National Grid) | Self-use offsets full retail; net excess credited near-retail, cap-exempt to 25 kW | Active (MDPU 1625) |
| SMART 3.0 | About $0.03 per kWh to the owner for 20 years | Active (Mass.gov) |
| State income-tax credit (Schedule EC) | 15% of net cost, up to $1,000 | Active (M.G.L. c.62 s.6) |
| Sales and property tax exemptions | 0% sales tax; 20-year property-tax exemption | Active (M.G.L. c.59 s.5) |
| Federal residential credit (Section 25D) | The 30% homeowner credit | Ended after December 31, 2025 (IRS) |
Is there still a federal solar tax credit in Massachusetts in 2026?
The federal homeowner credit is gone, but the Massachusetts programs are not. The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act, so a Woburn homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS Residential Clean Energy Credit; SEIA, as of 2026). You will still see installer pages and search prompts asking whether the 30% credit is going away in 2026; the accurate answer is that the homeowner version already ended. Net metering, SMART, and the state tax benefits were not affected, and at Massachusetts rates the bill offset alone is substantial. For the full timeline, see what the federal solar tax credit change means in 2026.
One federal exception exists, and it is not yours to claim. A separate commercial credit, Section 48E, is claimed by the business that owns a leased or PPA system, not by the homeowner (IRS Clean Electricity Investment Credit, as of 2026). On a leased system you do not file for a federal credit yourself; the company that owns the panels does. The 25D homeowner credit, by contrast, ended after December 31, 2025.
Woburn rooftops: simpler than Boston, with one local permit step
Woburn is mostly single-family suburban housing, which makes its solar projects more straightforward than Boston’s. Unlike Boston’s dense triple-deckers, flat row-house roofs, and historic districts, a typical Woburn home has a pitched single-family roof and sits outside any Boston Landmarks Commission review, so the design and approval are usually simpler. The high National Grid rate still drives a strong payback, and a suburban roof often has the room and the sun exposure to carry a system sized close to your usage.
Note: The one local step to plan for is Woburn’s own permitting. The city’s zoning Section 26 (Solar Photovoltaic Installations) requires solar plans stamped and signed by a Massachusetts-licensed Professional Engineer, along with a full site plan (City of Woburn zoning Section 26, as of 2026). A Woburn-experienced installer handles the engineering stamp and the paperwork for you, so ask whether they have done Woburn projects before.
| Woburn roof or site factor | What to plan for |
|---|---|
| Pitched single-family roof | A straightforward layout; size close to your annual usage |
| No Boston Landmarks review | No historic-district approval, unlike Boston neighborhoods |
| Woburn zoning Section 26 | PE-stamped plans and a site plan, handled by your installer |
| Older home or service panel | A possible electrical-panel check before adding solar or a battery |
| Shading from mature trees | A shade study; fewer, higher-efficiency panels may beat a full roof |
Paying for solar in Woburn: cash, loan, lease, or PPA
There is no single right way to pay for solar; the best fit depends on whether you want to own the system and keep the Massachusetts incentives yourself, or avoid an up-front cost. A lease or PPA can mean no up-front cost for eligible homeowners, but it is a long-term agreement with monthly payments, not free solar, and the system owner, not you, collects the SMART payment and the state tax credit. To weigh the long-run numbers, see the financial case for whether solar panels are worth it.
| Path | Up-front cost | Who keeps SMART + state credit | Best when |
|---|---|---|---|
| Cash purchase | Full system cost | You, the owner | You want the fastest payback and the most lifetime savings |
| Solar loan | Little to none, financed | You, the owner | You want ownership without paying cash up front |
| Lease or PPA | $0-up-front where eligible | The third-party owner | You prefer no up-front cost and a simpler, fixed monthly bill |
How to choose a solar installer in Woburn
Woburn and the Greater Boston market have a deep, competitive field of licensed installers, including national brands and Massachusetts companies, and one of the region’s largest installers is headquartered in Woburn itself, so there is real competition on price and service. Rather than leaning on a “best installer” list, screen any company against objective criteria and decide what to look for yourself.
- NABCEP certification, the industry’s professional standard for PV installers.
- A valid Massachusetts Home Improvement Contractor registration and proper electrical licensing.
- A clear workmanship and equipment warranty in writing.
- Real experience with National Grid interconnection and Woburn Section 26 permitting, so your application and Permission to Operate go smoothly.
- A written production estimate and a transparent quote that uses today’s SMART value, not an old one. For a checklist, see the right questions to ask a solar installer.

Frequently asked questions
Is solar worth it in Woburn, MA in 2026? For most owner-occupied Woburn homes with decent sun, yes. Massachusetts residential electricity averages about 30.21 cents per kWh (EIA, as of March 2026), among the highest in the country, so every kilowatt-hour your roof makes offsets an expensive grid one. National Grid net metering credits a home system near the retail rate, and the SMART program adds about $0.03 per kWh for 20 years on top. Savings are not guaranteed and depend on your roof, your usage, and how you pay, but the high local rate and the Massachusetts incentive stack make Woburn a strong solar market. As a mostly single-family suburb, it also avoids Boston’s historic-district hurdles.
Who is my electric utility for solar in Woburn? National Grid (Massachusetts Electric Company). Woburn, in Middlesex County north of Boston, is in National Grid’s electric service territory, not Eversource, which serves Boston (National Grid MDPU 1625, as of 2026). So your interconnection application and your net-metering credits all run through National Grid. If you want to compare, see how solar works in Boston on Eversource. Your installer files the National Grid interconnection before your system can turn on.
Does National Grid pay retail or wholesale for my solar exports? For a residential solar system, near retail, not wholesale. Power you use as you make it offsets the full retail rate. Net excess you export earns National Grid’s Standard Net Metering Credit, valued at the sum of the basic service, distribution, transmission, and transition charges, which lands near the retail rate (National Grid MDPU 1625, as of 2026). A system of 25 kW AC or less is cap-exempt and keeps that credit, and the credits carry forward billing period to billing period. The widely repeated claim that Massachusetts only pays a wholesale rate applies to certain non-solar projects, not a typical home solar system.
How does the Massachusetts SMART program work for a National Grid customer? SMART pays the system owner a flat incentive on every kWh your system generates, for 20 years. Under the SMART 3.0 redesign the state approved in May 2026, a residential system of 25 kW AC or less earns about $0.03 per kWh (Mass.gov SMART 3.0, as of 2026). The residential rate is set statewide, so it is the same on a National Grid account in Woburn as anywhere in Massachusetts, and systems under 25 kW are exempt from the capacity cap. If you add a qualifying battery, SMART adds a storage value set by a size-based formula, so ask your installer for the current figure.
What happened to the federal solar tax credit? The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act, so a Woburn homeowner who buys solar in 2026 with cash or a loan cannot claim it (IRS, as of 2026). A separate commercial credit, Section 48E, can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner. Massachusetts net metering, SMART, and the state tax benefits were not affected, so the local payback case still holds.
Do I need special approval to put solar on a Woburn roof? Usually not the kind Boston requires. Woburn is mostly single-family suburban housing and is outside any Boston Landmarks Commission district, so there is no historic-district review. The local step is Woburn’s zoning Section 26, which requires your solar plans to be stamped by a Massachusetts-licensed Professional Engineer and to include a site plan (City of Woburn zoning Section 26, as of 2026). A Woburn-experienced installer handles the engineering stamp and permitting for you. If your home is older, plan for a possible electrical-panel check before adding solar or a battery.
