Comparing quotes in Massachusetts?
Divide each quote's total, before incentives, by the system size in watts. Homeowners in Massachusetts who bought their system paid a median of $3.72/W in 2020–2022; each city page shows the local median. Reject any 2026 quote that subtracts a 30% federal tax credit from a purchase: that credit ended in 2025.

Solar Panel Repair in Massachusetts
When a system stops producing, start with an established local company: the ones ranked in each city above did the most work there in the latest records and know the equipment on local roofs. Many will service a system they didn't install, but not all — ask before you book, and expect a diagnostic fee. If your system is leased or on a PPA, call the company you pay each month first: maintenance is normally its job.
67% of the home systems installed in Massachusetts in 2020–2022 use SolarEdge inverters, followed by Enphase Energy (27%). Enphase systems use a microinverter under each panel, so one failure usually knocks out a single panel and the monitoring app shows which one. Systems with a central (string) inverter stop producing entirely when that inverter fails; a dark screen or an error code on the unit on your wall is the usual sign.

Installers in Massachusetts That Closed or Went Bankrupt
At least 10,030 home systems in Massachusetts were installed by these companies. Their panels and inverters are still covered by the manufacturers' warranties; the installer's workmanship warranty is likely gone. The city pages list the local companies still active that can take over service.
| Company | Systems in Massachusetts | What happened |

| Sungevity Development | 2,682 | Sungevity filed for Chapter 11 bankruptcy in March 2017. Solar Power World |

What Your Warranty Still Covers If the Installer Is Gone
- Panels and inverters: covered by the manufacturer, not the installer. Find the brand on the inverter label or in your monitoring app and contact the manufacturer directly.
- Workmanship and roof leaks: usually a promise from the installer. If the installer is in bankruptcy, that warranty may be delayed or discharged; file a claim in the case if one is open.
- Leases and PPAs: the system belongs to the finance company, and most contracts make it responsible for maintenance even if the installer that sold it is gone. Call the company you pay each month and check your contract.
- Loans: keep paying. A closed installer does not cancel a solar loan.
How Many Homes in Massachusetts Have Solar
Utilities in Massachusetts reported 214,085 homes with rooftop solar in 2026, with 1,531 MW of panels between them, or 7.2 kW per home on average. That is 14,654 more homes than a year earlier (+7%). Massachusetts ranks 6 of 44 states by the number of homes with solar. Home batteries paired with those systems add up to 32 MW.
Homeowners in Massachusetts pay an average of 29.61¢ per kWh for electricity, against 17.45¢ nationally. At this rate, a typical system takes roughly 10 to 15 years to pay back in the best case without the federal credit, so the price per watt you negotiate matters a lot. What solar costs and how long it takes to pay back.
These figures count homes enrolled in net metering or a similar program that credits the power they send to the grid, as reported by utilities. Homes on other arrangements may be missing, and a change in how a utility reports can make the numbers jump. Source: U.S. Energy Information Administration, Form EIA-861M, net metering, July 2026.
Solar in Massachusetts: Common Questions
Who installs the most solar panels in Massachusetts?
In 2020–2022, Sunrun installed 11,029 home systems in Massachusetts, more than any other company, followed by Trinity Solar (5,063) and Tesla Energy (1,333). Volume shows experience, not workmanship, so compare quotes and reviews before choosing.
How much does a solar system cost in Massachusetts?
Homeowners who bought their system outright paid a median of $3.72/W before incentives, and the typical system was 8.3 kW — about $31,000 in total. By city, the median ranged from $3.80/W in Boston to $4.49/W in Springfield.
Do most homeowners in Massachusetts buy or lease their panels?
45% bought their system and 55% leased it or signed a power purchase agreement (PPA). Leasing was most common in Lynn (88%) and least common in Boston (68%). With a lease or PPA you pay little upfront, but you don't own the panels and the savings are smaller over the contract.
Which Massachusetts cities install the most solar?
Among the cities we rank, Boston (1,167 home systems), Springfield (840 home systems) and Worcester (723 home systems) lead. Each city page ranks the local companies and shows prices, leasing and the installers that closed there.
Can I still get the federal solar tax credit in 2026?
Not as a homeowner buying the system: the 30% residential credit (Section 25D) ended on December 31, 2025. Be wary of any quote that still subtracts it from the price. See our 2026 solar tax credit guide for what's left.
What if my solar installer went out of business?
Your panels and inverters are still covered by their manufacturers' warranties; what you lose is the installer's workmanship warranty and service. See the installers that closed in Massachusetts and what your warranty still covers.
What do homeowners in Massachusetts pay for electricity?
Residential customers in Massachusetts pay an average of 29.61¢ per kWh, 70% above the national average. The higher the rate, the faster solar pays for itself. Source: EIA, Electric Power Monthly, Table 5.6.A.
