20solar companies rated
5 / 5Future Energy Solar (Top-rated)
  • We rated 20 Massachusetts solar companies on licensing, warranties, local presence, track record and options. The top three: Future Energy Solar (5, Top-rated), Boston Solar (5, Top-rated) and Sunrun (5, Top-rated).
  • Eversource, National Grid and Unitil credit extra solar power at close to the full kWh price and pay SMART 3.0 on every kWh for 20 years. The state is reviewing the credit value (D.P.U. 25-200), so ask for savings with today’s credit and a lower one.
  • The contracting company should hold an active HIC registration, and a licensed Massachusetts electrician must connect the system. Check both names on the state lookups before you sign.

What solar costs in Massachusetts

$3.02per watt installed
$26,395typical 8.74 kW system
$15,000 to $40,800for 5 kW to 12 kW

No federal credit for systems you own in 2026. The state credit is 15% up to $1,000, and there is no sales tax on the equipment. The range is EcoGen's installer-quote range at $3.00 to $3.40 per watt, before incentives. Batteries and roof work cost extra. Compare each quote’s price per watt with these numbers.

Solar incentives, tax breaks and rebates in Massachusetts

SMART 3.0
Eversource, National Grid and Unitil pay $0.03 per kWh of solar power your panels make, for 20 years, for home systems of 25 kW or less (2026 program year).
Lower-income SMART rate
Qualifying lower-income homes get $0.06 per kWh, about $410 a year for a typical system.
Net metering
Extra power earns a bill credit close to the full price of a kWh, and unused credits move to the next month and do not expire (Eversource, National Grid and Unitil).
State tax credit
15% of the system cost, up to $1,000, for a system you own on your main home; unused credit carries forward 3 years.
Sales tax
No 6.25% Massachusetts sales tax on solar equipment for your main home.
Property tax
The solar system is exempt from local property tax for 20 years.
Battery payment
ConnectedSolutions pays $275 per kW a year for an enrolled battery, $1,375 for one that gives 5 kW (Eversource, National Grid and Cape Light Compact customers).
Energy Saver Home Loan
A state loan of $10,000 to $100,000 at 0.5% or 2.0% fixed for 20 years, by income, for solar and batteries.
Federal credit
The federal tax credit is $0 for systems installed after December 31, 2025.

Who qualifies, deadlines and sources: Massachusetts solar incentives.

What to check with your utility

Eversource

  • SMART 3.0 pays $0.03 per kWh for 20 years on top of net metering; ask which program year rate your quote uses.
  • Cape Light Compact towns get power through Eversource, which will generally not pay out unused credits as cash. Size the system to your use.
  • ConnectedSolutions pays $275 per kW a year for an enrolled battery. Ask who handles enrollment.

National Grid

  • The same SMART 3.0 rate and near-retail net metering apply.
  • National Grid says ConnectedSolutions battery customers received $1,200 a year on average.
  • Ask who files the SMART and interconnection applications, and when the first SMART payment is due.

Unitil

  • SMART 3.0 and net metering apply under the same state rules.
  • Unitil customers cannot join ConnectedSolutions, so a quote that counts on a battery payment does not fit.

Municipal light plants

  • Town-owned utilities such as Belmont, Hingham, Holyoke, Reading and Taunton are outside SMART and the state net metering rules.
  • Each sets its own credit. Holyoke Gas & Electric credits all solar output at about $0.063 per kWh instead of net metering.
  • Some towns pay a rebate, such as Hingham's $0.60 per watt up to $6,000. Ask your light plant in writing before you request quotes.

Check the company and its warranty

Three names can appear in one solar deal: the company that sells, the company that signs the contract and the licensed people who do the work. Check that they fit together.

Before your first sales call, read questions to ask your solar installer and how to read a solar quote.

Compare your Massachusetts quotes

Ask every company to quote the same basics. Then the differences you see are real.

The boxes are for your own use. Nothing is saved or sent.

From quote to permission to operate

Some steps overlap, and timing depends on your town, your utility and equipment supply. Ask each installer for a written schedule for your project.

  1. Proposal and site check

    The installer looks at your roof, shading and electrical panel and gives you a written proposal.

    You and the installer
  2. Design and applications

    After you sign, the installer finishes the design and applies to your utility for the connection.

    Installer; you sign the forms
  3. Permits and utility review

    Your town or county reviews the building and electrical permits. The utility reviews the connection.

    Permit office and utility
  4. Installation and inspection

    The crew installs the system. A licensed electrician connects it, and the inspector checks the work.

    Installer crew, electrician and inspector
  5. Permission to operate

    The utility approves the system and updates your meter if needed. Turn the system on only after this step.

How we rate Massachusetts solar companies

Each company gets up to 100 points from facts anyone can check: its own website and Massachusetts’s public license records, read October 14, 2026. Facts a company does not publish earn no points. No company pays for its rating, and we do not use customer star reviews.

  • Licensing (30 points): an active state license, a licensed electrician and license numbers printed on its website.
  • Warranty protection (35 points): workmanship warranty length, roof-penetration coverage in writing and any production guarantee.
  • Local presence (15 points): an office in Massachusetts and Massachusetts named as a service area.
  • Track record (10 points): years installing solar.
  • Options (10 points): batteries and the number of ways to pay.

Stars: 85 points or more is 5 (Top-rated), 72 is 4.5 (Excellent), 60 is 4 (Very good), 45 is 3.5 (Good), below 45 is 3 (Average). We did not inspect installations, collect customer quotes or test customer service.

Massachusetts solar company FAQs

How do I check a Massachusetts solar installer?

Search the company on the MA Contractor Hub for an active Home Improvement Contractor registration, and check its electrical license on the Division of Occupational Licensure license search. The names must match your contract. Ask who connects the system to your panel; that work needs a licensed Massachusetts electrician.

Who pays SMART 3.0, and for how long?

Eversource, National Grid and Unitil pay it. A home system of 25 kW or less earns $0.03 per kWh for 20 years in the 2026 program year, or $0.06 for qualifying lower-income homes. In a lease or PPA the owner of the panels collects it, so ask how it lowers your price.

Does net metering still apply in Massachusetts?

Yes, for Eversource, National Grid and Unitil customers. Extra solar power earns a bill credit close to the full price of a kWh, and unused credits roll forward and do not expire. The Department of Public Utilities is reviewing the credit value in D.P.U. 25-200, so ask each installer to show savings with a lower credit too.

What if my town has its own light plant?

Municipal light plants are outside SMART and the state net metering rules. Each sets its own credit, and some pay a rebate instead. Ask your light plant in writing how it credits solar power before you ask for quotes, because the answer decides the right system size.

Will the companies on this page contact me?

Not because they appear here. This page is an editorial comparison, and no company pays for its place or its rating. If you request quotes, the providers that serve your area may contact you. They can include installers, marketplaces and lead exchanges.
