Solar panels and Massachusetts homeowners insurance: what actually gets covered.

Does homeowners insurance cover solar panels in Massachusetts

The honest answer is: it depends on your carrier and how you acquired the system, and you need to confirm it before installation, not after. The NAIC advises homeowners to check with their insurer before installing solar panels or a wind turbine, because some insurers extend homeowners coverage to these additions and some do not. Adding solar can also affect the cost of the policy significantly enough that the NAIC recommends calling your state insurance department first to understand your legal obligations for insuring the equipment. If your current insurer declines to extend coverage, the department can point you to an insurer authorized to offer it. There’s no Massachusetts Division of Insurance bulletin specifically addressing solar panels, so this is a carrier-by-carrier question, not a statewide rule you can assume applies. Before you sign an installation contract, call your agent or insurer and get a direct answer in writing about whether the panels are covered and under what form.

Ownership structure changes what you’re insuring

Massachusetts homeowners generally get solar through one of three paths: direct ownership, third-party ownership through a lease or power purchase agreement, or community shared solar, where you subscribe to a share of an off-site system and receive net-metering credits without installing anything on your own roof. Each path changes who actually has an insurable interest in the equipment. Under direct ownership, you own the system and its output and are generally responsible for maintaining it, which means it’s your equipment to insure. Under a lease, a solar company retains ownership while you pay monthly for use of the electricity, and you may not be responsible for upkeep. Under a PPA, a developer owns, operates, and maintains the system on your property, and you simply buy the electricity it generates at an agreed price.

This distinction isn’t academic. Some solar companies record a UCC-1 filing against the property when a system is leased or under a PPA. That filing is notice that a third party, not the homeowner, holds ownership rights in the panels. If a mortgage lender forecloses, the filing protects the solar company’s ownership; if the home is sold, it puts the buyer and their lender on notice that the panels aren’t part of the deal. The Attorney General’s Office advises reading solar agreements carefully for provisions that could restrict a future sale because of these filings. For insurance purposes, if you don’t own the panels, you likely don’t carry the primary insurable interest in them, even though they’re bolted to your roof. That’s a conversation to have explicitly with your insurer, not an assumption to carry into a claim.

Why there’s no single “solar panel rider” in Massachusetts

Searches for a “solar panel homeowners insurance rider Massachusetts” tend to assume a standardized form exists. It doesn’t. Massachusetts’ current incentive program, SMART 3.0, is set out in regulation 225 CMR 28.00, with revised regulations effective upon publication in the Massachusetts Register on September 12, 2025, following DOER’s filing on August 28, 2025. That program governs incentive payments for systems, including a flat per-kilowatt-hour rate for small systems of 25 kW AC or less. None of it dictates how a homeowners insurer must structure coverage for the panels themselves. Whether solar equipment falls under your policy’s dwelling coverage, personal property coverage, or requires a separate endorsement is a carrier-specific underwriting decision, and it varies by policy form. The practical move is to ask your insurer point-blank what applies to your system and get the answer in writing rather than assuming a rider exists by default.

What to tell your insurer before you install

A short checklist, straight from NAIC consumer guidance, covers most of what matters:

• Call your insurer before installation and ask whether solar panels are covered under your current policy or require a change.
• Ask what happens to your premium once the panels are added; the NAIC notes the cost impact can be significant.
• If you plan to sell excess energy back to the utility, ask about specific insurance obligations tied to that arrangement before setting it up.
• Review your policy yourself for any language on green upgrades, and if it’s silent, ask your insurer to address it directly rather than assuming silence means coverage.

Skipping this step and finding out at claim time that your carrier never extended coverage to the roof-mounted system is the scenario worth avoiding. It also affects renewal; carriers that view solar as an unrated exposure may non-renew rather than adjust the policy, so raising it proactively keeps you in control of the timeline. If you’re weighing whether to shop the policy instead of staying put, the general mechanics of switching are covered separately in how home insurance works in Massachusetts (/guides/how-home-insurance-works-in-massachusetts/).

Net metering, liability limits, and additional-insured requests

If your solar setup involves net metering, the insurance questions don’t stop at property coverage. Before finalizing a net-metering agreement, the NAIC advises asking the city and utility whether they’ll require proof of liability coverage, potentially ranging from $100,000 to $1 million per occurrence, along with indemnification. Separately, confirm with your own insurer that the liability portion of your homeowners policy doesn’t exclude net-metering-related accidents; that exclusion, if it exists, would leave a gap exactly where you need coverage. If you’re dealing with an energy cooperative rather than a standard utility, it may require the cooperative be named as an additional insured on your homeowners policy. Most government bodies either require or strongly encourage maintaining additional liability coverage for as long as the net-metering contract is active, and some municipalities require homeowners to agree to reimburse the town for losses arising from net-metering incidents that injure municipal workers or damage municipal property. None of these figures are Massachusetts-specific rules; they’re general NAIC guidance on what utilities and municipalities commonly ask for, so confirm the actual numbers with your utility and municipality before you sign.

Green endorsements: what some carriers add beyond standard coverage

Some insurers go further than basic coverage for homeowners generating their own solar, geothermal, or wind power and selling surplus back to the grid. These policies can cover the extra expense of temporarily buying electricity from another source and income lost during an outage, as long as the outage stems from a covered peril, plus utility charges for inspection and reconnection after getting back online. A separate feature some carriers offer, independent of a green endorsement, allows rebuilding to environmentally responsible standards after a fire or other covered disaster, even for policyholders who never purchased the green endorsement to begin with. None of this is universal. Because green policies and endorsements vary by insurer and aren’t offered by every carrier, the NAIC recommends shopping around, getting multiple quotes, and asking specifically about limits on covered costs and eligibility rules rather than assuming your carrier includes any of it. If you’re evaluating coverage across carriers generally, the shopping and switching guide (/guides/massachusetts-home-insurance-shopping-switching-companies/) covers the mechanics of comparing policies side by side.

If your insurer won’t cover solar-equipped homes: the FAIR Plan

If you can’t find a voluntary-market insurer willing to cover a solar-equipped home, or you’ve been declined, cancelled, or non-renewed, Massachusetts has a market of last resort: the Massachusetts Property Insurance Underwriting Association, known as the FAIR Plan. It’s regulated by the Division of Insurance, which reviews and approves FAIR Plan rates based on factors like market share, home value, construction type, location, and safety features. The FAIR Plan’s basic policy is described as relatively in line with coverage under a standard HO-3 policy, though generally more basic. Underwriting rules require the Coverage A dwelling amount to be at least 80% of the home’s replacement cost, and optional coverages beyond the basic policy are available through ISO endorsements. For homeowners whose solar installation has made voluntary-market placement difficult, the FAIR Plan guide (/guides/massachusetts-home-insurance-fair-plan/) walks through eligibility and how the coverage compares to a standard policy in more detail.
