Solar in Quincy, MA has a few wrinkles a generic Massachusetts guide will get wrong. The first is your utility: Quincy is National Grid, not Eversource like Boston next door, so your net metering and interconnection run through a different company. The second is the water: Quincy wraps Quincy Bay and Boston Harbor with miles of shoreline, and a waterfront roof has a few extra siting questions. The third is history: as the City of Presidents, Quincy has local historic districts where visible panels can need a sign-off. This page covers what going solar in Quincy actually involves in 2026, the real Massachusetts electricity rate, how National Grid net metering and the SMART program pay you, the coastal and historic details to plan around, and a payback estimate built from your local numbers, so you can check your address in about a minute. Updated for June 2026.
Quincy solar at a glance (South Shore, 2026)
Is solar worth it in Quincy in 2026? For most owner-occupied homes, yes. At the Massachusetts average rate of about 30.21 cents per kWh, a typical Quincy system pays back in roughly 7 years once net metering and the SMART payment are counted (EIA, as of March 2026).
- Your utility is National Grid, not Eversource. Quincy sits in National Grid’s Massachusetts territory, so your net metering, interconnection, and basic service run through National Grid, unlike Boston, which is Eversource (MassGIS Electric Utility Providers, as of 2026).
- Massachusetts power is expensive, 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.
- A 6 kW system on a Quincy roof models about 7,800 kWh a year. A per-address NREL PVWatts run for ZIP 02169 returns roughly 1,304 kWh per kW of panels (NREL PVWatts v8, as of 2026).
- Net metering credits a typical home near full retail. Residential systems of 25 kW or less are cap-exempt and earn the standard credit through National Grid (Mass.gov net-metering guide, as of 2026).
- SMART pays a per-kWh bonus on top. SMART 3.0 pays a residential system about 3 cents per kWh produced, or about 6 cents for income-qualified households, locked for 20 years (Mass.gov SMART 3.0, as of 2026).
- The 30 percent federal homeowner credit ended December 31, 2025. A 2026 cash or loan buyer in Quincy cannot claim it, so we do not count it in the savings math (IRS Residential Clean Energy Credit, as of 2026).
Why Quincy’s high electric rates make solar worth it
Quincy solar pays because National Grid delivery on the South Shore is expensive, and rising. Massachusetts residential power averages about 30.21 cents per kWh (EIA, as of March 2026), one of the highest rates in the country, so every kilowatt-hour your roof makes is one you do not have to buy back through National Grid at that price. If your Quincy electric bill runs past roughly $150 a month, your roof is probably worth a look. Because Massachusetts is a deregulated supply market, you might buy the energy portion of your bill from a competitive supplier or through the Quincy community electricity aggregation, but the delivery charge and your net metering still run through National Grid either way.
How much that rate saves you comes down to how much your specific roof makes. A per-address NREL PVWatts (v8) run for a Quincy ZIP (02169) models about 7,826 kWh in the first year from a 6 kW system, roughly 1,304 kWh for each kW of panels at a 14.9 percent capacity factor for Quincy’s coastal latitude (NREL PVWatts v8, as of 2026). Coastal Quincy gets a touch less sun than the drier interior, and the city’s mature street trees and tightly spaced older homes shade many roofs for part of the day, so two houses a block apart can model very differently. Get a site-measured number before you size anything, since production sets both your net-metering credits and your SMART payments.

What a Quincy solar system saves: our own estimate
Here is the math worked for Quincy, not a national average, with every input shown. We combined the live local production figure for ZIP 02169, the Massachusetts electricity rate, the standard SMART payment, and a typical Massachusetts installed price, then applied the state $1,000 income-tax credit. We left out the federal residential credit, which ended for expenditures made after December 31, 2025, so a 2026 buyer cannot claim it. Treat the result as a planning estimate, not a quote.
| System size | Est. annual production (1,304 kWh/kW) | Year-one bill offset (30.21 cents/kWh) | SMART payment ($0.03/kWh) | Est. annual benefit | Cost before incentives (~$3.25/W) | Est. simple payback after the $1,000 MA credit |
|---|---|---|---|---|---|---|
| 6 kW | about 7,820 kWh | about $2,365 | about $235 | about $2,600 | $19,500 | about 7.1 years |
| 8 kW | about 10,430 kWh | about $3,150 | about $315 | about $3,465 | $26,000 | about 7.2 years |
| 10 kW | about 13,040 kWh | about $3,940 | about $390 | about $4,330 | $32,500 | about 7.3 years |
Note: This estimate holds today’s rate flat, ignores loan interest, and uses a midpoint $3.25 per watt within the roughly $3.00 to $3.50 per watt Massachusetts range, so treat it as a planning range, not a quote (EnergySage, as of 2026). A household that qualifies for the income-eligible SMART rate of about 6 cents per kWh reaches payback faster, closer to 6.5 years on a 6 kW system. SMART payments also await Department of Public Utilities approval of a utility payment mechanism, expected in 2026, and systems that go live first still earn net-metering credits meanwhile. For the method behind numbers like these, see the financial case for whether solar panels are worth it.
Your Quincy utility is National Grid, not Eversource
A lot of homeowners just south of Boston assume they are on Eversource, but Quincy is National Grid for electricity. The Commonwealth’s official utility-territory map assigns Quincy to National Grid (Massachusetts Electric Company), while Boston proper is Eversource, so the company that delivers your power, reads your meter, and administers your solar is National Grid (MassGIS Electric Utility Providers, as of 2026). When you go solar, your net-metering credits, your SMART enrollment, and your interconnection application all run through National Grid. One local caution: not every South Shore town is National Grid, since nearby Braintree and Hingham run their own municipal light departments, so confirm the name on your own bill. For the contrast next door, see how solar works in Boston on Eversource, and for another National Grid city, how solar works in Lynn.
How National Grid net metering and SMART pay you in Quincy
On a National Grid account, net metering is what converts your extra production into money off the bill. Push more to the grid than you use on a sunny afternoon and National Grid banks the difference as a credit valued near the full retail rate, rolling forward from one month to the next (Mass.gov net-metering guide, as of 2026). Any residential system of 25 kW or less is cap-exempt, so a normal Quincy home always lands on the standard credit. The statewide rules sit on our Massachusetts solar guide and the explainer on how net metering credits your solar exports, and the utility specifics are on our National Grid Massachusetts net metering guide.
SMART pays a separate per-kWh incentive on top of net metering. Under SMART 3.0, the 2026 program year, a residential system earns a flat payment of about 3 cents per kWh produced over a 20-year term, about 6 cents for income-qualified households, and it stacks on top of your net-metering credits (Mass.gov SMART 3.0, as of 2026). A battery-paired system can also earn through National Grid’s ConnectedSolutions program, which pays you for letting the utility draw on your battery during peak demand events (National Grid ConnectedSolutions, as of 2026). For a battery, those utility payments now do much of the financial work.
| What pays you | How it works for a Quincy home | Who keeps it |
|---|---|---|
| National Grid net metering | Exports credited near full retail, rolling forward month to month | The National Grid account holder |
| SMART 3.0 payment | About 3 cents per kWh (about 6 cents income-qualified), for 20 years | The system owner |
| ConnectedSolutions | A seasonal payment for dispatching a home battery at peaks | The battery owner |
| The Massachusetts $1,000 credit | 15 percent of net cost, capped at $1,000, on Schedule EC | The system owner |
Note: Quincy is one of Massachusetts’ designated Gateway Cities and contains large areas mapped as 2020 Environmental Justice populations (MassGIS Environmental Justice Populations, as of 2026), so a meaningful share of Quincy households may qualify for the income-eligible SMART rate of about 6 cents per kWh, double the standard residential rate. Qualification is based on your household income, not just your address, so it is worth asking your installer to check when you get a quote.
What the federal tax-credit change means for Quincy
The federal homeowner credit is gone, but Massachusetts’ programs are not. The 30 percent federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a Quincy 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 national calculators implying a 30 percent credit through 2032; that is out of date for a 2026 homeowner purchase. Net metering, SMART, and the Massachusetts tax benefits were not affected, and at the state’s high rates the bill offset alone is substantial.
One federal exception exists, and it is not yours to claim. A separate commercial credit, Section 48E, can be 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, and it may pass some of the value through in your payments. The 25D homeowner credit, by contrast, ended after December 31, 2025. For the full timeline, see what the federal solar tax credit change means in 2026.
Solar on the Quincy waterfront
Quincy wraps the water, and a shoreline lot adds a few questions to a solar project. Quincy sits on Quincy Bay and Boston Harbor at the head of the South Shore and is commonly cited as having about 27 miles of coastline, one of the longer municipal shorelines in the area, with low-lying waterfront neighborhoods like Houghs Neck, Squantum, Germantown, Adams Shore, Merrymount, Marina Bay, and Wollaston Beach (Massachusetts Municipal Association, Quincy profile, as of 2026). None of that stops solar. It just means a few details matter more for a waterfront home than for an inland one.
Note: Flood risk is set parcel by parcel, so look up your exact address on the FEMA Flood Map Service Center (FEMA, as of 2026) rather than assuming your whole neighborhood is in or out of a flood zone. For a shoreline Quincy home, three siting details are worth raising with your installer: the racking and roof attachments should be engineered for the higher coastal wind and uplift loads in the local code; if your parcel is in a mapped flood zone, the inverter, electrical gear, and any battery are best kept above the base flood elevation, which matters most for ground-level or basement equipment; and a battery adds real backup value in a community exposed to coastal storm outages. Salt air also rewards corrosion-resistant hardware and a warranty that covers a coastal install.
Solar in a Quincy historic district, and who issues your permit
As the City of Presidents, Quincy carries real history, and for a small share of homes that adds one review step. Quincy is the birthplace of John Adams and John Quincy Adams and home to the federal Adams National Historical Park, and separately it has its own locally regulated historic districts under a city Historic District Ordinance, administered by the Quincy Historical Commission (City of Quincy Historical Commission, as of 2026). The designated local districts include the Quincy Center Historic District and the Adams Birthplace Historic District.
Note: This review applies only inside a designated local historic district, not citywide, and being on the National Register alone does not trigger it. If your home is in one of those local districts, exterior changes visible from a public way, which can include roof-mounted solar, may require a certificate of appropriateness from the Quincy Historical Commission before installation. Confirm your property’s status with the commission before you design the array, and choose an installer who can plan lower-visibility placement if needed.
For everyone else, your permit comes from the City of Quincy. Quincy is an incorporated city, so the building and electrical (wiring) permits for rooftop solar are issued by the City of Quincy Inspectional Services Department, filed online through the city’s ViewPoint Cloud portal (City of Quincy Inspectional Services, as of 2026). Quincy uses standard online plan review rather than an instant automated solar-permit path, so build a few weeks for permitting into your project timeline, and a good installer handles the city paperwork and the National Grid interconnection for you.
Paying for solar in Quincy: 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 Massachusetts incentives yourself, or avoid an up-front cost. The table 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. To weigh the long-run numbers, see the financial case for whether solar panels are worth it.
| Path | Up-front cost | Who keeps SMART plus the 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 Quincy
Quincy sits in a busy South Shore solar market, and its search results are noisy with national directories and even results for the other Quincys in Washington, Illinois, and beyond, so screen on what actually fits a Quincy, MA roof rather than a “best of” list (EnergySage Quincy marketplace, as of 2026):
- 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, and for a waterfront roof, one that covers a coastal install.
- Real experience with National Grid interconnection, City of Quincy permitting, and Quincy historic-district review if your home is in a local district, so the design and paperwork go smoothly.
- A written production estimate and a transparent quote that uses today’s SMART value, not an old one, and that tells you whether you qualify for the income-eligible rate. For a checklist, see the right questions to ask a solar installer.

Frequently asked questions
Is solar worth it in Quincy, MA in 2026?
For most owner-occupied Quincy 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 6 kW system at a Quincy ZIP produces about 7,826 kWh per year (NREL PVWatts v8, as of 2026), and net metering plus the SMART payment make our estimated payback roughly 7 years, faster if your household qualifies for the income-eligible SMART rate. Savings are not guaranteed and depend on your roof, usage, and how you pay, but the high local rate is what makes Quincy a strong solar market.
Who is my electric utility for solar in Quincy?
National Grid. The Commonwealth’s official utility-territory map assigns Quincy to National Grid (Massachusetts Electric Company), so your net metering, SMART enrollment, and interconnection all run through National Grid, not Eversource, which serves Boston (MassGIS Electric Utility Providers, as of 2026). Massachusetts is a deregulated supply market, so you may buy the energy portion of your bill from a competitive supplier or the Quincy aggregation, but National Grid still delivers the power and administers your solar credits. Two neighboring towns, Braintree and Hingham, run municipal utilities instead, so confirm the name on your own bill.
Is solar ever free in Massachusetts?
No. There is no program that gives Massachusetts homeowners panels at no charge, and solar panels are not free. What is real is the incentive stack: near-full-retail net metering on National Grid, the SMART per-kWh payment, the Massachusetts $1,000 income-tax credit, and the sales- and property-tax exemptions (Mass.gov SMART 3.0, as of 2026). Some homeowners can also go solar with no up-front cost through a lease or PPA, but that is financing with monthly payments, not free solar, and the company that owns the system keeps the SMART payment and the tax credit. Income-qualified households may also reach the higher SMART rate.
How do National Grid net metering and SMART pay me in Quincy?
Two ways that stack. Net metering credits the power your panels send to the grid near the full retail rate, and those credits roll forward month to month, with residential systems of 25 kW or less cap-exempt (Mass.gov net-metering guide, as of 2026). On top of that, the SMART program pays the system owner a flat per-kWh incentive for 20 years, about 3 cents per kWh for a standard residential system and about 6 cents for income-qualified households (Mass.gov SMART 3.0, as of 2026). A home battery can also earn through National Grid’s ConnectedSolutions program. SMART payments await Department of Public Utilities approval of a payment mechanism expected in 2026; systems that go live first still earn net-metering credits meanwhile.
Do I need historic-district approval for solar in Quincy?
Only if your property is inside one of Quincy’s designated local historic districts, such as the Quincy Center Historic District or the Adams Birthplace Historic District. There, exterior changes visible from a public way, which can include roof-mounted solar, may require a certificate of appropriateness from the Quincy Historical Commission before installation (City of Quincy Historical Commission, as of 2026). This applies only inside a designated local district, not citywide, and National Register listing alone does not trigger it. Confirm your address with the commission before you design the system, and an installer experienced with Quincy historic work can plan lower-visibility placement.
Does my Quincy home being near the water change a solar install?
It can add a few considerations, not a barrier. Quincy has a long shoreline and low-lying waterfront neighborhoods, and parts of the waterfront fall within FEMA-mapped flood zones, set parcel by parcel, so check your address on the FEMA Flood Map Service Center (FEMA, as of 2026). For a shoreline home, the racking should be engineered for higher coastal wind and uplift loads, the inverter and any battery are best kept above the base flood elevation if your parcel is in a flood zone, and corrosion-resistant hardware suits salt air. A battery also adds backup value given coastal-storm outage risk. An installer who works Quincy’s waterfront will plan for these.
What happened to the 30 percent federal solar tax credit?
The 30 percent federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a Quincy homeowner who buys solar with cash or a loan in 2026 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 Quincy’s high rates the local payback case still holds. See our guide on what the federal solar tax credit change means in 2026.
