Our Review of the Best Massachusetts Solar Companies
While all major solar providers offer similar equipment and basic warranties, our review explores each company’s expertise with Massachusetts-specific incentives, such as SMART Program enrollment and handling specialized permitting in historic districts. We don’t spend much time comparing basic solar panel efficiency or standard manufacturer warranties, as these tend to be consistent across installers.
Note that the average costs for each provider are from our national 2025 solar survey of 1,000 respondents.
Average Cost: $13,636
Company Overview
- Offers a 25-year system and roof warranty
- Provides remote monitoring through a mobile app
- Has transparent financing information online
Keep in Mind
- Doesn’t offer solar battery installation
- Requires a phone number to get an online quote
Our Review
Unlike some of the bigger national installers, Venture Solar is knowledgeable about Massachusetts’ local permitting quirks and historic district requirements, which makes a huge difference when dealing with New England housing. Its customer service team is notably responsive, and it has a couple of branches in the state, so Venture Solar understands firsthand the challenges of installing solar in the Bay State.
However, Venture Solar’s installation wait times can be longer than those of some competitors, especially during peak seasons. While its pricing is competitive, it doesn’t offer as many financing options as larger providers like ADT Solar. Venture makes up for this with its excellent post-installation support and monitoring services. Still, consider other options if you’re looking to get panels installed quickly or need specialized financing arrangements.
Compared to other local installers, Venture really shines in its detailed upfront cost analysis and expertise with the SMART Program incentives. While companies like Boston Solar might provide slightly faster installation times, Venture’s combination of local knowledge and transparent communication makes it a solid choice for Massachusetts homeowners.
Customer Experiences
Venture Solar has Better Business Bureau (BBB) accreditation, an A+ rating and a customer rating of 4.73 out of 5 stars. Positive reviews mention the professionalism and efficiency of Venture Solar’s scheduling and installation crews. More critical reviews mention frustration with how long inspection and activation take.
“There were no problems and they were done in 5 hours. They came right at 8 AM, began doing the roof setup, and then the electricians came (about 8:30) and worked on the main panel and then outside by the meter. They asked me if I preferred running the cables through my [attic]. Since my attic is basically a crawl space I said the roof was fine.” —Bobby J. via BBB in December 2024
“Despite my extreme patience and extensive communication with them, I have almost no response. A roof replacement was canceled/[postponed] with little to no communication. here are some of the details: Roof was supposed to be installed on 12/20 and was cancelled internally and I only find out because I called. The roof company canceled because somebody … at Venture told them to cancel … [Venture Solar] never calls. … I am worried I will lose your tax credit. The solar system was supposed to be installed on 12/23, but it will now be later. This is just unacceptable when I know I did everything I can to make sure this is done this year.” —Sandrine F. via BBB in December 2024
Average Cost: $14,812
Company Overview
- Holds a proven track record of operating in Massachusetts’ climate, with specific snow load considerations in its designs
- Offers strong battery backup options with its Brightbox system
- Provides a streamlined process for Massachusetts SMART Program enrollment and incentive paperwork handling
Keep in Mind
- Provides lease and power purchase agreement (PPA) contracts that can be complex and long-term (20–25 years)
- Has customer service that can be inconsistent due to the company’s size
Our Review
Sunrun has established itself as one of the biggest players in Massachusetts’ solar market. Its Brightbox battery backup systems are a game-changer for those notorious New England power outages. Sunrun is experienced at handling the state’s SMART Program incentives, and its zero-down financing options make solar accessible to more homeowners. Plus, if you’re a Costco member, you might get an attractive member-exclusive discount.
While Sunrun’s lease and PPA options might seem tempting with its zero-down offer, you’ll typically end up paying more over time compared to purchasing outright from a local installer. We’ve also noticed that customers mention communication hiccups and longer-than-expected wait times, which is a common trade-off when dealing with larger national companies. Sunrun’s 20- to 25-year contracts can be rigid, too, which is something you need to consider if you might eventually sell your home.
However, Sunrun does have some advantages over smaller companies. Its battery backup options are among the best, and its experience with utility connections can provide more peace of mind. If you’re interested in a lease or PPA rather than buying outright and you value working with a well-established national company, Sunrun could be your best bet.
Customer Experiences
Sunrun has an A+ rating with accreditation from BBB and a customer rating of 3.58 out of 5 stars. Customers report that their initial installation and activation went well and that they were producing energy efficiently. However, most critical remarks revolve around issues with ongoing support and difficult communication.
“I just completed my second year as a Sunrun customer and I have been very pleased with my solar panels and solar production. [My] Sunrun consultant, has been very helpful especially in how to understand my ComEd bills and how my solar panels save me money. He is very [thorough] in his explanations and patient with me. I highly recommend … Sunrun for the quality of service and excellent products.” —Kathleen R. via BBB in January 2024
“We have had the worst experience with them this year. We contacted SunRun regarding having our solar panels temporarily removed so we could replace our roof in February 2024. It took them until October to schedule the removal. The roof replacement was completed soon after, but the re-installation has only been partially done.” —Suzanne D. via BBB in December 2024
Average Cost: $17,307
Company Overview
- Offers BluePower Plus+ financing with 18 months of free solar before payments begin, which is unique in the Massachusetts market
- Customer reviews mention an excellent sales and installation process
- Uses in-house installation teams rather than subcontractors, leading to more consistent quality control
Keep in Mind
- Is less experienced with Massachusetts-specific programs like SMART compared to veteran installers
- Has limited battery storage options compared to competitors
Our Review
Blue Raven Solar has been making a name for itself in Massachusetts with its unique BluePower Plus+ financing program, which gives homeowners 18 months of solar power before payments kick in. Blue Raven has built a solid reputation for customer service and quick installations, often getting systems up and running faster than bigger players like Sunrun. Its in-house installation teams (rather than subcontractors) tend to deliver more consistent quality, which is especially important for those tricky New England weather conditions.
However, being relatively new to the Massachusetts market comes with some drawbacks. Blue Raven doesn’t have the deep experience with the state’s SMART Program or historic district requirements that local veterans like Boston Solar or Venture Solar bring to the table. Blue Raven’s limited battery storage options are also worth noting, especially given how frequent power outages can be during winter storms.
Compared to other Massachusetts providers, Blue Raven occupies an interesting middle ground. It lacks the comprehensive local expertise of Massachusetts-based installers and the national presence and resources of giants like Sunrun. However, Blue Raven beats both in terms of installation speed and pricing transparency. If you’re comfortable with a purchase-only model and don’t need extensive battery backup options, Blue Raven’s 18-month delayed payment program may make it an excellent choice.
Customer Experiences
BBB gives Blue Raven Solar an A+ rating and accreditation. The company also has a customer rating of 4.25 out of 5 stars. Customers praise Blue Raven for its professionalism and installation quality. However, some customers report confusion over promotional offers, spam calls, and not achieving the energy goals they were promised.
“I am very glad I choose Blue Raven Solar as my Solar company. They were professional from Sales man through installers and notifications from customer service. My only complaint would be the promise of one day installation. It took two different appointments to finish plus one more to fix some issues of inspection. … It took 5 weeks longer to get my system turned on than was planned. So all in all I would recommend Blue Raven Solar for a solar company. Just be prepared for some possible delays.” —Christopher D. via BBB in December 2024
“Fortunately, we were able to cancel within the 3-day period, but it would have been easy to take their word for all the promises that they made and believe everything they told you was in the contract. We had a phone consultation, and during the call, we were promised a $500 bonus check, the first 18 months of loan payments, and up to $1[,]500 for each referral (an increase over the standard referral bonus plan). We were about to wrap up the call, and the salesperson … had … come onto the line and coordinate our site visit, etc. She mentioned that any promises must be in writing to be valid. But, during the call, we were rushed to digitally sign all the paperwork while the salesperson kept asking if we were done yet so we did not have an opportunity to fully review the paperwork.” —Chris M. via BBB in December 2024
Average Cost: $21,812
Company Overview
- Offers competitive pricing compared to other national solar providers in the Massachusetts market
- Offers protection plan that includes active system monitoring and ongoing maintenance, which is valuable for Massachusetts’ weather
- Includes warranty coverage that features protection against snow and ice damage
Keep in Mind
- Has a relatively smaller presence in Massachusetts compared to more established local companies
- Receives some complaints about post-installation support
Our Review
Palmetto Solar has carved out an interesting niche in the Massachusetts market, particularly standing out with its protection plan. Think of it as a comprehensive solar system insurance policy that includes active monitoring and maintenance service. Palmetto’s digital tools are some of the best in the business, giving you real-time insights into your system’s performance through Massachusetts’ unpredictable weather. Price-wise, Palmetto is also quite competitive with other national providers, and it offers enough financing flexibility to make solar accessible to most homeowners.
However, Palmetto’s growing pains in Massachusetts are worth noting. Its reliance on subcontractors in some areas can also lead to inconsistent installation quality, and some customers mention longer-than-expected wait times for service during busy periods.
Compared to other solar providers in Massachusetts, Palmetto’s warranty and protection plan is more comprehensive. However, you’ll pay extra for that peace of mind. If you’re tech-savvy and value detailed insight into your system’s performance, Palmetto is a great choice.
Customer Experiences
Palmetto Solar has an A+ BBB rating but no accreditation. It also has a customer rating of 3.25 out of 5 stars. Positive reviews mention Palmetto’s responsive and helpful staff, including its customer service reps and installers. More critical reviews mention issues with ongoing support and getting customer service back on the phone after the initial installation.
“My experience with [my Palmerros Solar rep] has been nothing but positive. He has [done] a great job of explaining the process, being in contact every step of the way. All my questions and concerns were answered quickly and honestly. He went above and beyond getting this coordinated from the signing up to the actual installation. Completely satisfied.” —Paul R. via BBB in December 2024
“I am extremely frustrated with the activation process for my solar system. It has been four months since I purchased it, and its still not working. Today, a DTE technician came to inspect the system and provide permission to operate, but he informed me that he couldnt conduct the inspection because the system wasnt generating any energy. … After spending more than half an hour explaining to the Palmetto representative that this wasnt the issue and providing all the details I received from the DTE technician to prove that the system wasnt functioning, the Palmetto representative finally understood. He then advised me to contact the sales representative. Seriously?I” —Emerson E. via BBB in November 2024
Average Cost: $19,682
Company Overview
- Has experienced in-house installers for proper and efficient installation
- Offers customized solar solutions tailored to individual energy needs through a virtual consultation process
- Includes a 25-year warranty on workmanship and equipment for leased systems
Keep in Mind
- Might yield long contract terms and early termination fees
- Features a limited selection of solar products and services
Our Review
Momentum is one of the larger players in Massachusetts’ solar market, and it has built a solid reputation for offering full-service solar installations with in-house teams rather than relying on subcontractors. We appreciate Momentum’s virtual consultation process, which is convenient for busy homeowners. However, Momentum’s pricing tends to be a bit higher than some local competitors, and customers mention that wait times for installation can stretch longer than initially quoted.
Companies like Boston Solar tend to offer more competitive pricing and often have shorter installation timelines. Other installers are typically more flexible with equipment options, too, allowing you to choose from different panel and inverter manufacturers—Momentum primarily sticks to its preferred vendors. However, if you want to lease your system, Momentum allows you to keep its 25-year warranty. Most companies reduce or remove this warranty when you lease.
Customer Experiences
Momentum Solar is BBB-accredited with an A+ rating, but it holds a middling customer rating of 2.89 out of 5 stars. Negative reviews tend to focus on aspects outside of Momentum’s actual solar installation process, such as persistent sales tactics or problems with transferring a previous homeowner’s system. Positive reviews mention professional and helpful customer service reps—and that the company has helped reduce energy costs as outlined in each quote.
“Amazing experience since day one! Everything they promised was just how it was. My electric bill is much much lower than what I was paying. … Customer service was great always there for me. … the whole process for installation was smooth sailing …” —John S. via BBB in May 2024
“I sold house with Momentum Solar Panels with the purchase agreement to new owner. Real estate agreement contract was to transfer new owners when house was sold. House was sold October 10, 2024. I have [talked] to many [reps] from Momentum to get solar panel purchase agreement to change it to new owners for house. What are you [supposed] to do? I am still getting Momentum Solar Panel bill!” —Steven S. via BBB in December 2024
Local Massachusetts Solar Companies
When it comes to local installers, we recommend Boston Solar. Founded in 2011 in Woburn, the company has installed thousands of residential solar energy systems across the state. What makes Boston Solar particularly appealing compared to national providers is its deep local expertise. For example, its installation teams know how to handle everything from Cambridge’s strict historical preservation requirements to Cape Cod’s coastal weather considerations.
While national companies like Sunrun or Venture Solar might offer marginally better pricing, Boston Solar makes up for it with faster response times, more personalized service, and an intimate understanding of Massachusetts incentive programs. Plus, its crews consist of only in-house employees, and it maintains a dedicated local customer service team that knows the state well.

How To Choose the Best Solar Company
When choosing a solar installer in Massachusetts, you should look beyond price to make sure you’re getting a company that can handle the state’s unique challenges. The ideal installer should have experience with New England’s weather conditions, local building codes, and historic district requirements. It should also have a proven track record of navigating the state’s complex incentive programs, particularly the SMART Program.
Here are the key factors to consider:
- Credentials and insurance: Make sure the installer has a Massachusetts electrical license and a North American Board of Certified Energy Practitioners (NABCEP) certification. We also suggest checking for proper liability and workers’ compensation insurance, as well as a local BBB rating.
- Experience and local knowledge: Check how many years the company has operated in Massachusetts to get an idea of its familiarity with local historic preservation requirements, as well as experience with snow load calculations and winter-ready installations.
- Financial factors: Look for a company offering a variety of financing options, such as solar loans, leases, and PPAs. You also want a company with experience securing Massachusetts-specific incentives—and a company that is transparent in its pricing and fees. To get an even better price, request at least three quotes from providers to find the most competitive offer.
- Installation and equipment: Ask whether the installer uses in-house installation teams or subcontractors. In-house is preferred to keep things simple for you. Also, ask whether the company conducts roof assessments and can provide any repairs or replacements required for solar panel installation. It’s a good sign if the installer is upfront about the panel and inverter brands offered.
- Service and support: Find an installer with a local customer service presence rather than a huge corporate call center. Check for quick service call response times. To secure the best support, you want a company with ongoing system monitoring options, multiple energy solutions, maintenance services, and snow removal plans. At the least, the company should provide warranty coverage for both equipment and workmanship.

FAQs About Solar Companies in Massachusetts
Do Massachusetts solar companies handle all the paperwork for incentives and permits?
Most established solar companies in Massachusetts will handle all paperwork, including SMART Program enrollment, building permits, historic district approvals (if needed), and utility interconnection applications. However, you should confirm this upfront, as some companies might charge extra for certain applications or require more involvement from homeowners.
How long does the solar installation process take in Massachusetts?
From contract signing to system activation, the solar process typically takes two to six months. However, this can vary significantly based on factors such as local permitting requirements, historic district reviews, utility company response times, and seasonal installation backlogs. Winter installations might take longer due to weather conditions.
What happens if my solar panels get damaged by snow or ice?
Most reputable solar installers in Massachusetts include snow and ice damage in their warranties. However, you should verify coverage details, as some companies might require additional insurance or maintenance plans to fully protect against winter weather damage.
Can I install solar panels on my historic home?
Yes, but if your property is in a historic district, you’ll need approval from your local historic commission. The best Massachusetts solar companies have experience working with historic commissions and can design systems that meet preservation requirements while maintaining efficiency.
How We Evaluated Massachusetts Solar Companies
We ranked the top solar energy system installation companies on their service options, performance guarantees, certifications, and experience. We ensured that, at the minimum, each company offers high-quality monocrystalline solar panel installation and backup battery storage options.
Our Rating System
To determine the best of the best in residential solar energy, we created a rigorous methodology that helps us analyze providers on significant service options to the most minute details of warranty coverage. We assess each company in six key areas.
Here’s a breakdown of our solar panel installer methodology:
- Solar equipment and services: We review each provider’s service catalog to learn what residential solar services they offer and whether they offer additional helpful services, such as a dedicated app or web portal, energy audits, monitoring services, and roofing services. These services both help speed up and maintain solar panel installation. We also check whether a provider uses in-house installation crews or outsources to a third-party company.
- Warranty and performance guarantees: We review each company’s warranty coverage and guarantees to ensure adequate coverage and protection for factory malfunctions or improper installation issues. Companies that offer 25 years or more of workmanship and performance receive the most points, and companies that include a production guarantee or roof-leak coverage receive additional points.
- Brand reputation and professional certifications: We check each provider on the Better Business Bureau (BBB) and analyze hundreds of recent customer reviews to gain insight into what it’s like to work with that company. Additionally, we check for ongoing lawsuits and company alerts and that the company holds NABCEP (North American Board of Certified Energy Practitioners) certification.
- Financing options: We review each company’s payment and financing options. The more payment methods a company offers, the more points it receives. However, leasing and PPAs receive fewer points, as we find them less desirable for long-term cost-effectiveness. We also give additional points if the company provides in-house financing rather than relying on you to find a third-party lender.
- Industry experience: The longer a company has been in the residential solar industry, the more points it receives.
- State availability: We check each provider’s service area. The more states it offers solar panel and battery installation in, the more points it receives.
