Loan, cash, PPA or lease, with no money down on three of the four options.
Rooftop Power has completed more than 480 installations in Massachusetts, concentrated along the South Coast in towns like Attleboro, Seekonk, Fall River, New Bedford and Swansea. The same employees who design your system pull the permit, install it and stand behind it.
Massachusetts homes are served by Eversource, National Grid or Unitil depending on where you live, and the interconnection paperwork differs by utility. We confirm your utility and rate class first, then prepare and submit the application for you.
The state SMART program pays solar owners for production, and capacity and rules change by utility territory and block. We check current availability for your address as part of your quote and put what you qualify for in writing.
South Coast homes deal with salt air, wind load and a mix of housing ages from New Bedford three deckers to newer builds in Attleboro and Seekonk. We size systems to your actual annual usage, inspect the roof before we ever talk panels, and handle the town permit and utility paperwork ourselves.
In Massachusetts your first lever is net metering. When your system makes more electricity than the house needs, the extra goes back to the grid and your utility credits the account. Massachusetts homes are served by Eversource, National Grid or Unitil, and both the value of the credit and the caps that govern how much can be net metered vary by utility and by the size class your system falls into. Smaller residential systems are treated differently from larger ones, which is one reason we confirm your utility and rate class before we ever put a number on paper.
The bigger piece in Massachusetts is SMART, short for Solar Massachusetts Renewable Target. SMART is a declining block incentive: it pays a set per kilowatt hour rate on the power your system produces over a ten year term. The rate you lock in is set by whichever block is open in your utility territory at the time you enroll, and there are adders that can raise it, for example for pairing the system with battery storage. Because blocks fill and the rates step down as they do, both timing and territory move the final number.
Net metering and SMART work alongside each other, but the exact math is specific to your address. There is no single Massachusetts answer, which is precisely why a local installer that files these applications every week is worth more here than a national one working from a spreadsheet.
Your utility credits the surplus you send back. Credit value and caps vary by utility and by system size class, so we confirm both before quoting.
A declining block incentive paying a set per kilowatt hour rate on production over ten years. The rate depends on the open block in your territory when you enroll, with adders such as storage available.
SMART blocks fill and rates step down over time. Which block is open at your address when you enroll changes the number, so when and where you are matter.
Rooftop Power confirms your utility, your rate class and the current SMART block for your address before we quote, then shows you what your home actually qualifies for in writing.
Completed Rooftop Power installations by town, straight from our project records.






Every pin is a completed Rooftop Power installation. Our own in-house crews cover Massachusetts from our Warwick, Rhode Island headquarters.
The programs and payment options a homeowner in Eversource, National Grid and Unitil territory should know about.
Your utility credits your account for the power your system sends back to the grid.
The Solar Massachusetts Renewable Target program pays for the energy your system produces over a set term.
Your incentive path depends on which of the three serves your home. We confirm it before we design.
We put the full financing picture in front of you before you commit to anything.
We do not quote federal tax credits or guaranteed dollar savings. Rooftop Power reviews the current state programs with you and puts the real numbers for your home in writing.
The same six steps on every job, run by our own crews from the first bill review to the day the system switches on.
We start with a look at your recent Eversource, National Grid or Unitil bills, your roof and how your household uses power. You get a straight read on whether solar makes sense for your home, with no pressure and nothing owed.
Our designers size a system to your actual annual usage and your roof, then put the full price, the financing options and the production estimate in writing so you can compare it against your current Eversource, National Grid or Unitil bill line by line.
We pull the local building permit and file the Eversource, National Grid or Unitil interconnection application for you. This is the paperwork that stalls a lot of projects, and our own team handles all of it in house.
Our own electricians and roofers install the system, never a subcontractor. If the roof needs work, we handle that first so you are not pulling panels off a failing roof a few years down the road.
The town inspector and Eversource, National Grid or Unitil both sign off on the finished system. We schedule the inspections and meet them on site, so you never have to chase anyone down.
Once Eversource, National Grid or Unitil grants permission to operate, we switch the system on and your billing arrangement begins. We stay your point of contact for monitoring, service and questions long after the crew has gone.
Solar is the start. One local team also handles the battery, the EV charger, the generator and the roof underneath it.
On the South Coast, wind and salt storms take the grid down more than anyone would like. A battery keeps your essentials running through an Eversource or National Grid outage, and pairing storage with solar can also unlock a SMART adder, so it can pull double duty.
Learn moreMassachusetts has one of the highest EV adoption rates in the country. Charging on your own rooftop production instead of some of the highest electric rates in the country is the whole point, and we install home chargers built around your system.
Learn moreFor homes that want more than a battery can carry, a standby generator runs the whole house through a multi day outage. We size and install it alongside the solar so it is one team and one plan.
Learn moreSouth Coast roofs take a beating from salt air and wind, and a lot of the housing stock is older. We inspect the roof first, and because we replace roofs in house, we get yours solar ready before the panels ever go on.

Learn moreThe electricians and roofers on your roof are Rooftop Power employees, not a rotating cast of subs. That is why the same team that designs your system is the one that stands behind it years later.
We are one of the most reviewed solar and roofing companies in the region. Read what Massachusetts homeowners actually say before you ever pick up the phone, because our reputation is the whole pitch.
We hold our own electrical and construction licenses in all three states we serve, and we are BBB A+ accredited. Every Massachusetts permit and interconnection is filed under our licenses, not borrowed ones.
A solar array is only as good as the roof beneath it. Because we do both, we can replace or repair your roof as part of the project instead of sending you to a separate contractor and hoping the timing lines up.
We are not a national dealer network routing your job to whoever bids lowest. We are a Massachusetts installer run out of Warwick, Rhode Island, and our name is on every truck and every job.
Outstanding service from start to finish. The team at Rooftop Power was professional, knowledgeable and efficient, and our installation was completed on schedule.
Fantastic experience with Rooftop Power. From the initial consultation to the final inspection, everything was handled professionally.
