Solar pays in Haverhill because Massachusetts power is expensive, about 28.82 cents per kWh (EIA, May 2026). Your utility is National Grid. A typical 6 kW roof makes roughly 7,680 kWh a year, and net metering plus SMART 3.0 turn that output into bill savings.
- High rates are why solar works here. Massachusetts residential electricity averages about 28.82 cents per kWh (EIA, as of May 2026), nearly double the national average, so every kilowatt-hour your roof makes replaces an expensive grid one.
- Your electric utility is National Grid. Haverhill sits in National Grid’s Massachusetts Electric territory in the Merrimack Valley, so your net metering runs through National Grid (verify your own address on Mass.gov Find My Electric Company, as of 2026).
- Net metering credits a normal home near full retail value. Residential systems of 25 kW or less are cap-exempt under Massachusetts law (Mass.gov net-metering guide, as of 2026).
- SMART 3.0 adds a per-kWh payment on top. The state approved the SMART 3.0 redesign in 2026; it pays the system owner a per-kWh incentive over a multi-year term. Ask your installer for the current value for a National Grid account (Mass.gov SMART, as of 2026).
- Haverhill’s older mill-city housing adds a couple of checks. Many homes carry older 100-amp service panels or knob-and-tube wiring that a solar plus battery project may need upgraded first.
- The 30% federal homeowner credit (Section 25D) ended for systems placed in service after December 31, 2025 (IRS, as of January 1, 2026), so a Haverhill homeowner who buys solar in 2026 cannot claim it.
Haverhill homeowners pay some of the highest electricity prices in the country, which is exactly why rooftop solar pays off in this Merrimack Valley city. The math is simple: the more your power costs, the more each solar kilowatt-hour saves you. What makes a Haverhill project distinct is the local detail, your National Grid net metering, the older mill-era housing stock, and the Massachusetts incentives that still apply after the federal homeowner credit ended. This page covers what solar actually costs in Haverhill, how net metering and SMART work with National Grid, and the Haverhill-specific things to plan around, then you can check your address in about a minute.
Why Haverhill’s electric rates make solar worth it
The reason solar pays in Haverhill is the price of the power it replaces. Massachusetts residential electricity averages about 28.82 cents per kWh (EIA, as of May 2026), one of the highest rates in the nation and close to double the U.S. average. So every kilowatt-hour your roof makes offsets an expensive one you would otherwise buy from National Grid. A Haverhill home spending $150 or more a month on electricity is a strong solar candidate. For the exact cents on your own bill, read the supply and delivery lines on your National Grid statement, since both reset on a schedule.
Your production is what turns that high rate into savings. Using NREL’s PVWatts model for Haverhill (ZIP 01830), a typical 6 kW rooftop system produces about 7,680 kWh a year, at a local solar resource of 4.65 kWh per square meter per day (NREL PVWatts v8, as of 2026). According to MySolarFY’s analysis (August 2026), that 7,680 kWh of production, valued at Massachusetts’ 28.82 cents per kWh, offsets roughly $2,213 of grid electricity in a year for a Haverhill home. Your real number depends on your roof’s pitch, shading, and orientation, so estimate your own roof rather than lean on an average.

Your Haverhill utility is National Grid
Haverhill’s electric utility is National Grid, in its Massachusetts Electric service territory across the Merrimack Valley. Massachusetts gives each utility an exclusive electric territory, so there is no overlap at a given address, and Haverhill and its neighbors like Methuen and Lawrence sit in National Grid’s northeastern Massachusetts footprint rather than Eversource’s (verify your specific address on Mass.gov Find My Electric Company, as of 2026). Unlike some nearby communities that run their own municipal light plants, Haverhill is investor-owned National Grid territory, so your interconnection, net metering, and Permission to Operate all go through National Grid. Note that National Grid may also be your gas provider, but it is the electric account that governs your solar credits. For the statewide rules behind all of this, see our Massachusetts solar guide and the National Grid Massachusetts net metering page.
How National Grid credits the power your Haverhill roof sends back
Net metering is the engine of your savings, and in Haverhill it credits a normal home near full retail value. Massachusetts net metering is set by state law and regulation, M.G.L. c.164 sections 138 and 139, not by the utility, and a residential system of 25 kW or less is cap-exempt after the state raised the residential threshold to 25 kW AC (Mass.gov net-metering guide, as of 2026). So a typical Haverhill home is never shut out, and the credit is valued near the full bundled retail rate rather than the reduced market credit that applies to much larger systems. When your panels make more than you use, the excess goes to the grid and National Grid banks net-metering credits in dollars that roll forward month to month. 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 | Near full retail value, tracked in dollars and rolled forward | The National Grid account holder |
| Year-end leftover balance | A lower tariff rate, below retail | The account holder |
| SMART payments | A per-kWh incentive over a multi-year term | The system owner |
Massachusetts solar incentives on a Haverhill National Grid account
Beyond net metering, a Haverhill homeowner stacks the same statewide Massachusetts benefits as the rest of the state. These go to the system owner, so on a lease or PPA the company that owns the panels keeps the incentive, 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 the SMART 3.0 redesign the state approved in 2026. It pays the system owner a per-kWh payment over a multi-year residential term, with an added value for pairing a battery (Mass.gov SMART program, as of 2026). The value is set by the state and resets over time, so ask your installer for the current figure for a National Grid account rather than budgeting around an old number.
- A state income-tax credit (Schedule EC) worth 15% of the net system cost, capped at $1,000 (Mass.gov solar and wind energy credit, as of 2026).
- A 100% sales-tax exemption on qualifying solar equipment, off the state’s 6.25% rate (DSIRE Massachusetts, as of 2026).
- A 20-year property-tax exemption on the added home value from a qualifying solar system, under Clause 45 (M.G.L. c.59 s.5, Clause Forty-fifth, as of 2026).
These benefits are the same in Haverhill as anywhere in the state, which is why we keep the full statewide detail on our Massachusetts solar guide and the Massachusetts net metering and SMART guide rather than repeating it here.
What the federal tax-credit change means for Haverhill
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 Haverhill 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 asking whether the 30% credit is going away; 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 Haverhill’s high 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.
Going solar on an older Haverhill home
Haverhill’s mill-era housing stock is what makes its solar projects distinct. As one of the Merrimack Valley’s older industrial cities, Haverhill has a lot of nineteenth- and early-twentieth-century wood-frame homes, triple-deckers, and converted mill buildings, and the age of a building adds a few checks a newer suburban home usually skips. Many older Haverhill homes still run a 100-amp electrical service panel, or even legacy knob-and-tube wiring in parts of the house, that may need an upgrade to carry a modern solar system safely, especially if you also want a battery, EV charging, or heat pumps. An older roof also usually needs a structural look and, on a two- or three-family, your co-owners’ sign-off before panels go up.
Note: Solar in Haverhill needs an electrical and building permit from the City of Haverhill Inspectional Services, plus National Grid interconnection approval before it can switch on. If your home is in one of Haverhill’s older or historic neighborhoods, confirm any local review with the city before you sign. A good rule for an older home: budget for a possible panel or wiring upgrade and get it checked during the site visit, not after the array is designed. An installer who works in the Merrimack Valley will know the local permitting and National Grid interconnection steps.
| Haverhill roof or site factor | What to plan for |
|---|---|
| 100-amp service panel | May need an upgrade for solar plus a battery or EV charging |
| Older or knob-and-tube wiring | An electrical check; some rewiring may be required before install |
| Aging or steep New England roof | A structural and condition check; re-roof first if it is near end of life |
| Two- or three-family home | Co-owner approval and a clear roof-rights agreement before install |
| Winter snow and shading | A shade study and a tilt that sheds snow; production dips in deep winter |
Paying for solar in Haverhill: 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 at a high level. 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 state tax credit. To weigh the long-run numbers, see 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 Haverhill
The Merrimack Valley has a deep market of licensed installers, from local Massachusetts companies to regional brands, 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 Haverhill permitting, plus any panel or wiring upgrade an older home may need, so the paperwork 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.
MySolarFY matches you with licensed installers that serve your area so you can compare real local quotes side by side, with no obligation.

Frequently asked questions
Is solar worth it in Haverhill in 2026?
For most owner-occupied Haverhill homes with decent sun, yes. Massachusetts residential electricity averages about 28.82 cents per kWh (EIA, as of May 2026), among the highest in the country, so every kilowatt-hour your roof makes offsets an expensive grid one. A typical 6 kW system in Haverhill makes about 7,680 kWh a year (NREL PVWatts v8), net metering credits a normal home near full retail value, and the SMART incentive adds a per-kWh payment on top. Savings are not guaranteed and depend on your roof, usage, and how you pay, but the high local rate is what makes Haverhill a strong solar market.
Who is my electric utility for solar in Haverhill?
National Grid. Haverhill sits in National Grid’s Massachusetts Electric territory across the Merrimack Valley, and Massachusetts utility territories do not overlap, so net metering for a Haverhill home is administered by National Grid, not Eversource (verify your address on Mass.gov Find My Electric Company, as of 2026). Unlike some nearby towns with municipal light plants, Haverhill is investor-owned National Grid territory, so your interconnection and Permission to Operate go through National Grid.
How does net metering work with National Grid in Haverhill?
When your panels produce more than you use, the extra flows to the grid and National Grid credits your account in dollars at near the full retail rate, and those credits roll forward month to month (Mass.gov net-metering guide, as of 2026). Residential systems of 25 kW or less are cap-exempt, so a typical home always qualifies for the standard credit. The smart move is to size your system close to your annual usage, since a large year-end surplus is trued up at a lower rate.
Does Massachusetts still have solar incentives in 2026?
Yes. A Haverhill homeowner can still use the SMART 3.0 per-kWh incentive, a state income-tax credit of 15% of net system cost capped at $1,000 (Schedule EC), a 100% sales-tax exemption on qualifying equipment, and a 20-year property-tax exemption on the added home value (Mass.gov SMART; DSIRE Massachusetts, as of 2026). These state programs were not affected by the end of the federal homeowner credit. Ask your installer for the current SMART value for a National Grid account.
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 Haverhill 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 at Haverhill’s high rates the local payback case still holds.
Can I get solar with no up-front cost in Haverhill?
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 is the path that keeps them. Check what you qualify for before deciding.
Reviewed by the MySolarFY team. Figures were verified against the linked Massachusetts (Mass.gov / DOER / DSIRE), EIA, NREL PVWatts, and IRS sources as of August 2026; net-metering true-up rates, the SMART 3.0 value and term, National Grid interconnection steps, and Haverhill permitting can change, so confirm current terms with National Grid, the City of Haverhill, and Mass.gov before you decide.
