The Massachusetts Solar Market Is Crowded — That Is Not Always a Good Thing

Massachusetts has hundreds of solar companies competing for your business, from large national chains to small local outfits. The Bay State ranked 4th in the nation for solar jobs, and more than 60% of those workers are installers. That is a lot of people knocking on doors and making promises.

The challenge for homeowners is separating the companies that will deliver quality work from the ones chasing a quick commission. Massachusetts has seen a surge in consumer complaints — the Attorney General's Consumer Advocacy & Response Division (CARD) has processed hundreds of solar-related complaints in recent years, many involving misleading sales tactics, confusing contracts, and unfulfilled promises. The good news: a little homework goes a long way.

How to Verify a Solar Company in Massachusetts

Every solar installer working on existing residential homes in Massachusetts must be registered as a Home Improvement Contractor (HIC) with the Office of Consumer Affairs and Business Regulation. This is not optional — it is state law. You can verify any contractor's registration at the official HIC Contractor Search tool at services.oca.state.ma.us. Check that their registration is active, note their HIC number, and confirm the business name matches who you are dealing with. If a company cannot provide their HIC registration number, that is your cue to walk away.

Beyond the HIC registration, look for companies that carry both general liability insurance and workers' compensation coverage. Ask how long they have been installing solar specifically in Massachusetts — navigating Eversource and National Grid interconnection processes, pulling permits in Boston versus Springfield versus Worcester, and designing systems for New England's snow loads requires real local experience. A company that just entered the Massachusetts market last year will not have the same institutional knowledge as one that has been here for a decade.

Red Flags That Should Send You Running

The Massachusetts Attorney General's office has fielded hundreds of solar complaints, and the patterns are consistent. Watch out for any company that pressures you to sign today with a "limited-time offer" — legitimate incentives like the federal tax credit and MREC do not expire tomorrow. Be wary of salespeople who promise specific dollar savings without seeing your electric bill or assessing your roof. And if someone knocks on your door and will not take "no" for an answer, contact local law enforcement — the AG's office has specifically flagged this behavior. Also scrutinize any contract longer than you would expect to live in your home, especially if the escalation clause is buried in the fine print.

Other warning signs include companies that will not provide a written quote, those that ask for large upfront deposits before any work begins, and installers who cannot explain how net metering works with your specific utility — whether that is Eversource or National Grid. If they cannot tell you the difference between those two utilities' interconnection processes, they do not know Massachusetts well enough to be on your roof. File complaints with the AG's Consumer Advocacy & Response Division online or by calling (617) 727-8400.

Frequently Asked Questions

How do I verify a solar company is licensed in Massachusetts?+
Every solar installer must be registered as a Home Improvement Contractor (HIC) with the Massachusetts Office of Consumer Affairs and Business Regulation. You can search for any company at the official HIC Contractor Search tool online. Look for an active registration status and confirm the business name matches.
What should I do if a solar company uses high-pressure sales tactics?+
Do not sign anything under pressure. Legitimate solar companies will give you time to review contracts and compare quotes. If a door-to-door salesperson refuses to leave, contact local law enforcement. You can also file a complaint with the Massachusetts Attorney General's Consumer Advocacy & Response Division at (617) 727-8400.
Should I choose a local Massachusetts solar company or a national chain?+
Local companies tend to have deeper knowledge of Massachusetts permitting, Eversource and National Grid interconnection processes, and New England roof conditions. National chains may offer competitive pricing but often subcontract installation to local crews. The key is verifying HIC registration, insurance, and local experience regardless of company size.
How many quotes should I get before choosing a solar installer?+
Getting two to three quotes is a reasonable approach for comparing pricing, equipment, and warranty terms. Make sure each company provides a written quote that includes system size, panel brand, warranty details, and a clear breakdown of costs and incentives. Be cautious of any company that pressures you to skip this step.
What questions should I ask a solar company before signing a contract?+
Ask for their HIC registration number, proof of insurance, how long they have installed solar in Massachusetts, whether they use in-house crews or subcontractors, what panels and inverters they use, their warranty terms, and how they handle Eversource or National Grid interconnection. Also ask for references from recent installations in your area.
What is the biggest complaint about solar companies in Massachusetts?+
The most common complaints involve misleading savings projections, confusing contract terms, and aggressive door-to-door sales. Some homeowners have reported being locked into 20-year contracts with escalation clauses they did not understand. Always read the full contract and ask about rate escalators before signing.

Is Solar Really Free in Massachusetts?

While you can’t technically get “free” solar panels anywhere, they are “free” in the sense that you can expect to pay less for solar than you already do for electricity — and it costs nothing to make the switch.

So you’re swapping out an unpredictable and constantly increasing electric bill for a price protected solar payment that is usually about 40% lower. While it isn’t exactly “free”, it’s about as close as it gets.
