Updated for 2026.
Lawrence homeowners pay some of the highest electricity prices in the country, which is exactly what makes rooftop solar pay off in this Merrimack Valley mill city. The details that decide your numbers are local: your utility is National Grid, not Eversource; Lawrence is a Gateway City that sits almost entirely inside a state environmental-justice community, so many households qualify for the doubled low-income SMART rate; and the city’s older triple-decker and mill-era housing stock brings a few roof and electrical checks a newer suburb skips. This page, updated for 2026, covers what solar actually costs in Lawrence, the Massachusetts incentives you may qualify for, how net metering works with National Grid, and the local factors to plan around, then you can check your address in about a minute.
What decides your Lawrence solar numbers in 2026
- Massachusetts power is expensive, which is what makes solar pay here. Residential electricity averages about 30.21 cents per kWh (EIA, as of March 2026), well above the national average, so every kilowatt-hour your roof makes offsets an expensive one you would otherwise buy.
- Your electric utility is National Grid, not Eversource. Lawrence sits in National Grid’s Massachusetts electric territory in the Merrimack Valley, so your net metering runs through National Grid (MassGIS Public Utility Service Providers, as of January 2026).
- A typical 6 kW roof in Lawrence makes about 7,844 kWh a year. That is NREL’s modeled output for ZIP 01841; nearby 01840 and 01843 model around 7,636 kWh (NREL PVWatts, as of 2026).
- The SMART rate pays more here for income-eligible homes. SMART 3.0 pays a flat $0.03 per kWh to a residential system owner, and $0.06 per kWh, double, for a qualifying low-income household (Mass.gov SMART 3.0, as of June 2026). Lawrence is one of the state’s lowest-income Gateway Cities, so many residents can access the doubled rate.
- Net metering credits your extra power and rolls it forward. A residential system of 25 kW AC or smaller is cap-exempt and net meters even when caps are full, with credits that carry over month to month (Mass.gov net-metering guide, as of July 2026).
- The 30% federal homeowner credit (Section 25D) ended after December 31, 2025 (IRS, as of January 1, 2026), so a Lawrence homeowner who buys solar in 2026 cannot claim it. The state programs above were not affected.
What does solar cost and save in Lawrence?
A typical 6 kW system in Lawrence runs roughly $17,000 to $19,200 before incentives and pays back in about 6 to 7 years, or closer to 5.5 to 6.5 years for an income-eligible household on the doubled SMART rate. That estimate uses Lawrence-area installed pricing of about $2.85 to $3.20 per watt (EnergySage Lawrence cost data, as of 2026), the EIA state electricity rate, and NREL production, with the Massachusetts $1,000 income-tax credit applied. The full math is in the table below.
Because installed cost, roof output, and your own electricity use all move the number, treat this as an illustrative estimate, not a quote. For statewide cost benchmarks, see our guide on how much solar panels cost, and run your own address for a real figure.

Why Lawrence’s electric rates make solar worth it
The reason solar pays in Lawrence is the price of the 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 delivery plus supply in the Merrimack Valley sits in that expensive range. So every kilowatt-hour your roof makes offsets an expensive grid one. A Lawrence household spending $150 or more a month on electricity is a strong solar candidate. The EIA figure is a statewide average, so for your exact cents read the supply and delivery lines on your own National Grid bill, since both reset on a schedule.
Your production is what turns that high rate into savings. Lawrence gets a solar resource typical of northeastern Massachusetts, and NREL models a 6 kW system at about 7,844 kWh a year in ZIP 01841, or roughly 7,636 kWh in 01840 and 01843 (NREL PVWatts, as of 2026). Because output depends on your roof’s pitch, shading, and orientation, and dense city blocks add shading from neighboring three-deckers and street trees, 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 before you size a system.
| Lawrence ZIP | Modeled 6 kW output (kWh/year) | Daily sun resource (kWh/m2/day) |
|---|---|---|
| 01841 | 7,844 | 4.71 |
| 01840 | 7,636 | 4.59 |
| 01843 | 7,636 | 4.59 |

Your Lawrence utility is National Grid, not Eversource
A lot of Merrimack Valley homeowners assume they might be on Eversource, but Lawrence is National Grid for electricity. Massachusetts gives each utility an exclusive electric territory, so there is no overlap at a given address, and Lawrence sits in National Grid’s Massachusetts electric distribution territory, the same one that covers nearby Merrimack Valley communities (MassGIS Public Utility Service Providers, as of January 2026). You can confirm your own address on the state’s Find My Electric Company tool (Mass.gov, as of June 2026). Because National Grid administers your net metering and interconnection, its rules are the ones that shape your solar credits. For the utility-wide detail, see our National Grid Massachusetts solar guide, and for the statewide rules behind all of this, the Massachusetts solar guide.
How National Grid credits the power your Lawrence roof sends back
Net metering is the engine of your savings, and in Massachusetts the rules are set by the state, not the utility. A residential system of 25 kW AC or smaller is a nameplate cap-exempt facility, meaning it can net meter even when the program caps are full, after the state raised the cap-exempt threshold from 10 kW to 25 kW AC (Mass.gov net-metering guide, as of July 2026; DPU order D.P.U. 23-140-A, as of November 2024). So a typical Lawrence home is never shut out. When your panels make more than you use, the excess flows to the grid and National Grid credits your account under the state net-metering tariff (220 CMR 18.00), and those credits roll forward from month to month. Sizing your system close to your yearly usage keeps the most value on your own bill. For the mechanics, see how net metering credits your solar exports.
| What you earn | How it is valued | Who receives it |
|---|---|---|
| Monthly net-metering credits | Under the state net-metering tariff (220 CMR 18.00), tracked and rolled forward month to month | The National Grid account holder |
| SMART incentive | A flat per-kWh payment over a 20-year term | The system owner |
| SMART low-income adder | Double the standard per-kWh rate for a qualifying household | The system owner |
Massachusetts solar incentives on a Lawrence account
Beyond net metering, a Lawrence homeowner stacks the same statewide Massachusetts programs as the rest of the state, and the low-income SMART rate is where Lawrence stands out. These incentives go to the system owner, so on a lease or PPA the company that owns the panels keeps them, while the net-metering bill credit still follows your National Grid account.
- SMART (Solar Massachusetts Renewable Target), the state’s per-kWh incentive, now running as SMART 3.0. For a residential system of 25 kW AC or smaller it pays the system owner a flat $0.03 per kWh, locked for a 20-year term, and $0.06 per kWh, double, for a qualifying low-income household (Mass.gov SMART 3.0 Program Details, as of June 2026). There is also an optional energy-storage adder set by a $0.04 storage multiplier, with the actual per-kWh value calculated by formula and varying by system, so ask your installer to model it for your battery.
- A state income-tax credit (Schedule EC) worth 15% of the net system cost, capped at $1,000, claimed on your Massachusetts return for a principal residence (Mass.gov residential energy credits, as of 2026). It is a one-time credit with a three-year carryforward.
- A 100% sales-tax exemption on qualifying solar equipment, off the state’s 6.25% rate, claimed with a Form ST-12 exempt-use certificate (Mass.gov sales and use tax; DSIRE, as of 2026).
- A property-tax exemption of at least 20 years on a qualifying solar system, extendable by agreement with the town, under M.G.L. c.59 s.5 Clause 45 (DSIRE, as of 2026).
Note: Lawrence is a designated Massachusetts Gateway City and lies almost entirely inside a state-designated environmental-justice community (MassGIS 2020 Environmental Justice Populations, as of 2026). If your household income qualifies you as a low-income participant, your SMART rate doubles to $0.06 per kWh, which meaningfully shortens payback. Ask any installer to check your eligibility for the low-income SMART rate before you sign, because it is easy to leave on the table.
These statewide benefits are detailed in full on our Massachusetts solar guide rather than repeated here, which keeps this page focused on what is specific to Lawrence.
Your estimated payback in Lawrence, step by step
Here is the original math for a typical Lawrence roof, so you can see where the payback number comes from. The table below computes an estimate for a 6 kW system using the figures gathered above: NREL production for ZIP 01841, the EIA state electricity rate, Lawrence-area installed pricing, and the Massachusetts $1,000 credit, for both a standard household and an income-eligible one on the doubled SMART rate. It is an illustrative estimate to show the method, not a quote or a guarantee.
| Input or result | Standard household | Income-eligible household |
|---|---|---|
| System size | 6 kW | 6 kW |
| Modeled annual production (ZIP 01841) | 7,844 kWh | 7,844 kWh |
| Estimated installed cost ($2.85 to $3.20/W) | $17,100 to $19,200 | $17,100 to $19,200 |
| Massachusetts Schedule EC credit (one-time) | minus $1,000 | minus $1,000 |
| SMART rate | $0.03/kWh ($235/year) | $0.06/kWh ($471/year) |
| Estimated annual electricity savings at 30.21 cents/kWh | about $2,370 | about $2,370 |
| Estimated combined first-year benefit | about $2,605 | about $2,841 |
| Estimated simple payback | about 6 to 7 years | about 5.5 to 6.5 years |
Assumptions: production from NREL PVWatts (6 kW, ZIP 01841, as of 2026); electricity value from the EIA Massachusetts average of 30.21 cents/kWh (as of March 2026), applied to production as avoided grid purchases; installed cost from EnergySage Lawrence data (as of 2026); SMART from Mass.gov (as of June 2026); Massachusetts Schedule EC credit of $1,000. Payback ignores the small annual bill offset from SMART years beyond year one and any financing cost, and no federal credit is included because Section 25D ended after December 31, 2025. Your result depends on your roof, usage, and pricing. To weigh the long-run numbers, see whether solar panels are worth it.
What the federal tax-credit change means for Lawrence
The federal homeowner credit is gone, but 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 Lawrence homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS Residential Clean Energy Credit; IRS OBBB FAQ, as of 2026). You will still see installer pages, and even Google’s own AI answers, saying the 30% credit is available; the accurate answer for 2026 is that the homeowner version already ended. Net metering, SMART, and the state’s tax benefits were not affected, and at Lawrence’s high rates the bill offset plus SMART still carry the payback. 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.
Going solar on a Lawrence triple-decker or mill-era home
Lawrence’s older housing stock is what makes its solar projects distinct. Many homes here are triple-deckers and wood-frame mill-era houses, which often have roof area for a good-sized system, but the age of the building adds two checks a newer suburban home usually skips. First, older homes may still run a legacy 60 to 100-amp electrical service that can need an upgrade to carry a modern system, especially if you also want a battery or EV charging. Second, an older roof usually needs a look at its remaining life, because you do not want to install panels on a roof that needs replacing in a few years, and a structural check on older framing.
Note: On a multi-family triple-decker, whether solar connects to one unit’s meter or is shared across the building is a program and metering question, not just a wiring one, so it is worth raising with your installer and, for a two or three-unit building, your co-owners before you design the system.
| Lawrence roof or site factor | What to plan for |
|---|---|
| Triple-decker or mill-era roof | Often fits a solid system; check remaining roof life and racking for the roof type |
| Legacy 60 to 100-amp service panel | May require a service upgrade for solar plus a battery or EV charging |
| Multi-family or multi-meter building | Confirm which meter the system serves and get co-owner sign-off first |
| Dense city block | A shade study for neighboring three-deckers and street trees; higher-efficiency panels may beat a larger array |
| Income-eligible household | Ask your installer to confirm low-income SMART eligibility, which doubles the SMART rate |
Paying for solar in Lawrence: 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 claim the state incentives yourself, or avoid an up-front cost. The table below compares the common paths. 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.
| 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 Lawrence
Lawrence is served by a competitive market of licensed installers, many based in the surrounding Merrimack Valley towns such as North Andover and Methuen, which is good for you because it means real competition on price and service. Rather than chasing a “best installer” list, screen any company against objective criteria:
- NABCEP certification, the industry’s professional standard for PV installers.
- A valid Massachusetts Home Improvement Contractor (HIC) registration and electrical licensing.
- A clear workmanship and equipment warranty in writing.
- Real experience with National Grid interconnection and Lawrence permitting, so the paperwork and Permission to Operate go smoothly, and with older Lawrence housing if your home is a triple-decker or mill-era build.
- A written production estimate and a transparent quote that uses today’s SMART value and checks your low-income SMART eligibility, not an old federal-credit assumption. For a checklist, see the right questions to ask a solar installer.
MySolarFY matches you with licensed installers that serve your area so you can compare real local quotes side by side, with no obligation. You can also see how nearby Merrimack Valley cities compare on our Lowell solar and Lynn solar pages, and read how MySolarFY works and our data and methodology.
Frequently asked questions
Is solar worth it in Lawrence in 2026?
For most owner-occupied Lawrence 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. A typical 6 kW roof here models about 7,844 kWh a year (NREL PVWatts, as of 2026), net metering credits your extra power, and the SMART incentive adds a per-kWh payment on top, doubled if your household qualifies as low-income. Savings are not guaranteed and depend on your roof, usage, and how you pay, but the high local rate makes Lawrence a strong solar market.
Who is my electric utility for solar in Lawrence?
National Grid. Lawrence sits in National Grid’s Massachusetts electric distribution territory in the Merrimack Valley, and Massachusetts utility territories do not overlap, so net metering and interconnection for a Lawrence home run through National Grid, not Eversource (MassGIS Public Utility Service Providers, as of January 2026). You can confirm your own address on the state’s Find My Electric Company tool. You may buy gas from a different company, but your electricity and your solar credits go through National Grid.
How much does a solar system cost in Lawrence?
A typical 6 kW system runs roughly $17,100 to $19,200 before incentives at Lawrence-area pricing of about $2.85 to $3.20 per watt (EnergySage Lawrence data, as of 2026). After the Massachusetts $1,000 income-tax credit and with the SMART incentive and net-metering savings, we estimate simple payback around 6 to 7 years, or 5.5 to 6.5 years for an income-eligible household on the doubled SMART rate. This is an illustrative estimate, not a quote; your cost depends on system size, roof, and equipment. Run your address for a real figure.
Does Lawrence’s low-income SMART rate really double the incentive?
Yes, for a qualifying household. SMART 3.0 pays a residential system owner a flat $0.03 per kWh, and $0.06 per kWh for a low-income participant, over a 20-year term (Mass.gov SMART 3.0, as of June 2026). Lawrence is one of Massachusetts’ lowest-income Gateway Cities and lies almost entirely within a state environmental-justice community (MassGIS 2020 EJ Populations, as of 2026), so many residents can access the doubled rate. Eligibility is by household income, so ask your installer to confirm whether you qualify before you sign.
How does net metering work with National Grid in Lawrence?
When your panels produce more than you use, the extra flows to the grid and National Grid credits your account under the state net-metering tariff, and those credits roll forward month to month (Mass.gov net-metering guide, as of July 2026). A residential system of 25 kW AC or smaller is cap-exempt and net meters even when the program caps are full, after the state raised the residential threshold from 10 kW to 25 kW AC. The smart move is to size your system close to your annual usage so you keep the most value on your own bill.
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 Lawrence homeowner who buys solar in 2026 with cash or a loan cannot claim it (IRS, as of 2026). Some search results and AI answers still say the 30% credit is available; that is out of date for homeowner purchases. 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.
Can I get solar with no up-front cost in Lawrence?
Some homeowners can, through a lease or power purchase agreement (PPA) where eligible, which can mean no out-of-pocket cost at installation in exchange for monthly payments. This is not free solar; it is a long-term agreement, typically 20 to 25 years, and total payments may exceed the cost of a cash purchase. On a lease or PPA the third-party owner, not you, collects the SMART payment and the state tax credit, while your benefit is a lower or fixed power price. If you want to own the system and capture those incentives yourself, a cash purchase or solar loan keeps them. Check what you qualify for before deciding.
