Sunrun

Founded in 2007, Sunrun has become one of the nation’s top solar energy companies. Sunrun works in more than 20 states and territories in the US, including Massachusetts. They provide customers several options for financing and leasing; Sunrun handles the whole process of installing solar panels, from figuring out the size of the system to helping customers find tax incentives. 

They offer several solar panel systems, such as battery storage technology like the Tesla Powerwall. These products come with good warranties. The company's designs can be changed to fit each property, and has several different brands of solar energy equipment.

Bottom Line:

Sunrun is a great option for homeowners looking for flexible financing or leasing options. Although Sunrun has some negative customer reviews, most customers have had positive experiences. 

Cost, Warranty & Services

Sunrun offers flexible financing and leasing options, including $0 down payment plans. Sunrun also provides a 10-year comprehensive warranty for purchased and leased systems. Depending on the equipment and whether or not it is bought or leased, there may be other warranty options. 

Average Cost

Sunrun estimates that most solar systems can cost between $15,000 and $29,000, but the total amount depends on power consumption and home size. Sunrun will send a technician to review plans and create a quote with specific costs for your project. 

Warranty 

The Sunrun Guarantee covers purchased and leased solar energy systems. This 10-year comprehensive warranty covers parts, labor, and roof penetrations. Sunrun's products may also come with equipment warranties that last anywhere from 12 to 25 years, depending on the service area and the equipment manufacturer. Sunrun's advisors are the best people to talk to about the details of your solar project's warranty coverage.

Solar Services

Sunrun services all of Massachusetts. They offer customized solar equipment designs, installations, permitting, and powering up. They also have a range of products, including the Tesla Powerwall and its own battery backup system. 

Financing Options

Sunrun offers purchase and lease options, either paid in full or monthly. Sunrun's advisors will go over the details during the consultation, but the monthly lease and purchase options require $0 to a small down payment. 

Specials or Incentives Offered

Sunrun doesn't advertise any specific deals or incentives, but homeowners in Massachusetts can get a number of tax credits or rebates for installing solar panels, including the federal solar tax credit. Most of the time, residents who lease their solar energy systems can't get these, but your electric utility company or Sunrun may be able to help you get other incentives. 

In-House or Contracted Installations

It’s more likely that Sunrun uses contractors for installations in Massachusetts. Most solar installations are done by certified installers that Sunrun works with, but in some states, the company may have its own teams. 

Brands of Solar Equipment Offered

Sunrun uses high-efficiency monocrystalline panels from solar suppliers like Costco and Longi. They also offer the Brightbox Home Battery Storage and the Tesla Powerwall for home energy backups. 

Customer Reviews

Sunrun has had an "A-" rating with the BBB since 2009. With over 2,600 reviews, customers rate Sunrun 4 out of 5 stars on average. Most of the bad reviews say that the sales team was pushy and that the consultation process wasn't clear, but most people have had good experiences working with the solar company. 

Partnerships

Sunrun has partnerships with Massachusetts-certified solar installers. Sunrun has its own technology for storing energy in batteries, and it works with Tesla Powerwall to make it better. Sunrun is also a Solar Energy Industries Association-certified solar company.

ACE Solar

ACE Solar is one of the best solar companies in Massachusetts, and its main office is in North Andover. They work with people and businesses all over the Northeast. In Massachusetts, they serve people from the North Shore, MetroWest, Cape, and Mendon. They only started their business in 2015, but for the past six years, they have been ranked as the number one solar EPC contractor in Massachusetts. 

Although their products are on the expensive side, they have strong customer reviews and satisfaction to back their work. And since they’re locally owned and operated, they tend to have more experience with Massachusetts government and utility company solar incentives.

Bottom Line:

Massachusetts residents are lucky to have ACE Solar as a local solar installer. But their website needs more information about prices and guarantees, and some people have said that their work costs more. 

Cost, Warranty & Services

ACE Solar offers a variety of financing and purchase options, both in-house and through state solar loans, leases, and power purchase agreements (PPAs). But their website doesn't list all of the options, estimated costs, or warranty details, so it's best to talk to an ACE solar advisor. 

Average Cost

Solar panel installations vary in cost depending on electricity consumption and property size. Most people in Massachusetts should expect to pay between $15,000 and over $25,000, but an ACE solar specialist will confirm the exact cost after figuring out what the project needs. 

Warranty 

ACE Solar doesn't say what their equipment and work warranty is, but most equipment warranties last up to 25 years, which is about how long solar panels last on average. The best way to find out about ACE Solar's warranty is to contact them directly. It depends on the type of equipment and how you buy it. 

Solar Services

ACE Solar works in several states in the Northeast, including Massachusetts, Rhode Island, New Hampshire, and Maine. Massachusetts residents have access to a range of solar energy products, and the solar company works with residential and commercial projects. They also do solar work for rooftops, ground-mounted projects, and canopies. 

Financing Options

ACE Solar advertises financing and leasing options for solar energy projects on its website. Residents of Massachusetts may also be able to get financing through SMART, which stands for Solar Massachusetts Renewable Target. But an ACE Solar consultant will talk to you about your project's exact loan, purchase, and lease options. 

Specials or Incentives Offered

Other than a $250 referral program, ACE Solar's website doesn't list any current deals or incentives. But if you live in Massachusetts, the state or your local utility company may offer special financing, a rebate, or a tax credit incentive program. It’s important to note that leased solar panels may not qualify for tax credits. 

In-House or Contracted Installations

ACE Solar does not mention if they use contracted installers for their solar projects, so it’s likely that the company mostly handles projects in-house. 

Brands of Solar Equipment Offered

Third-party reviews say that LG solar panels and SolarEdge solar inverters, which are used by ACE Solar, are some of the most energy-efficient equipment on the market. However, because ACE Solar offers several services, they may have other brands of solar equipment depending on the project. It’s best to speak with them directly to learn what solar equipment they use.

Customer Reviews

The BBB gives ACE Solar an “A+” rating and accreditation, but the company doesn’t have many customer reviews compared to the other best solar companies in Massachusetts. However, ACE Solar has been ranked as the #1 residential and commercial solar contractor in Massachusetts for six years in a row by Solar Power World magazine. 

Partnerships

ACE Solar works with customers throughout the Northeast region, primarily in Massachusetts. They work with both residential and business clients. Their solar professionals and electricians have certificates from the NABCEP, which is one of many awards and credentials they have.

Palmetto Solar

Palmetto Solar was started in 2010 and now has offices in Massachusetts and 24 other states. They are one of the best solar installers in the country, and they sell a variety of solar energy products to homeowners, such as battery storage systems for when the power goes out. They say that installing solar panels can cost as little as $85 a month for people in Massachusetts, and they take care of the whole process, from design to inspection. 

Palmetto Solar is a national company, so the contractors they use and the quality of their work may differ from one state to the next. Still, they boast an “A+” rating on BBB and have a full-service, dedicated customer support team.

Bottom Line:

Palmetto Solar is quickly growing as one of the nation’s leading solar companies, and Massachusetts residents can count on full support from start to finish. However, Palmetto Solar’s website lacks clear information on solar energy equipment brands and financing. 

Cost, Warranty & Services

Palmetto Solar says that solar panels can be bought for as little as $85 per month, but it doesn't say how long the loan is or what other buying or leasing options are available. They also have a range of other solar products available, like battery storage technology. Palmetto Solar backs its installations with a 12-year product warranty and a 25-year performance warranty, one of the best in the industry. 

Average Cost

Palmetto Solar doesn’t quote average costs since every project will vary. They do, however, have a cost and savings calculator on their website for people in Massachusetts. Installing solar panels usually costs between $15,000 and $25,000, depending on how much electricity the property uses, how big it is, and how much power the owner wants. 

Warranty 

Palmetto Solar backs its installations with a 12-year product warranty and a 25-year linear performance guarantee, which is also called an output warranty. Their solar installations also come with three years of Palmetto Protect coverage, which includes system monitoring, reporting, service, and support. However, customers must purchase additional coverage to extend these benefits beyond three years. 

Solar Services

Palmetto Solar offers consultation and installation services in several states, including Massachusetts. Their team oversees the complete process of design, permits, and diagnostics for residential properties. Palmetto Solar also offers services like installing battery storage, cleaning solar panels, and getting rid of pests.

Financing Options

If you live in Massachusetts and want to finance through Palmetto Solar, you will need to talk to an advisor to find out what your options are. On its website, the solar company doesn't say exactly how financing works, but it does say that monthly payments start at $85. Furthermore, Massachusetts residents may qualify for the state’s HEAT loan program, which offers financing up to $25,000. 

Specials or Incentives Offered

Palmetto Solar's website doesn't list any ongoing specials or incentives, but residents of Massachusetts can still get federal and state solar tax credits and incentive programs to help lower the initial costs of installation. 

In-House or Contracted Installations

Palmetto Solar is a national solar company, so it hires local contractors to do installations. But Palmetto Solar has customer service and project management teams that work in-house and are available for the whole project. 

Brands of Solar Equipment Offered

Palmetto Solar uses different solar equipment for each project and location, but they say they use solid black premium panels with a power rating between 395 and 405 watts and an efficiency of more than 19.8%. 

Customer Reviews

The BBB gives Palmetto Solar an “A+” rating and accreditation, and over 160 customers rate the company 4 out of 5 stars on average. Most of the reviews were positive, and the ones that weren't said that there were long wait times and project delays, which were mostly fixed. 

Partnerships

Palmetto Solar has several partnerships in 25 states, including Massachusetts. However, not all services and equipment partners will be available to homeowners in every region, so it’s best to speak with an advisor from Palmetto Solar to learn about their partnerships in your area.

Momentum Solar

Momentum Solar is a New Jersey-based solar company founded in 2009. Today, they do business in 11 states, including Massachusetts, and offer a full line of solar products and easy-to-use tools. Momentum Solar has a mobile app that allows homeowners to monitor their project’s progress and system production data, making it easy to follow the process and receive updates. 

Also, they have plans to buy, rent, or finance, but a Momentum specialist will talk to you about the specifics during the planning process. But even though Momentum Solar has great solar services, its customer reviews aren't as good as those of the best solar companies in Massachusetts.

Bottom Line:

Momentum Solar has one of the most user-friendly and efficient solar systems available, but its customers’ experiences haven’t always been positive in some areas. 

Cost, Warranty & Services

Momentum Solar, like many other solar companies, doesn't list prices on its website. Instead, the price is set after the initial consultation with a company representative. They do offer a competitive 25-year warranty, but depending on the purchase plan, the maintenance options may be different. Momentum also partners with Enphase to offer battery backup systems.

Average Cost

Momentum Solar doesn't give out average prices for solar installations in Massachusetts because the size, equipment, and amount of electricity each project makes are different. However, some reviews report average pricing with upfront cost expectations. 

Warranty 

Momentum Solar backs its products with a 25-year warranty, which is the same as the best warranties in the solar industry. Momentum tells you exactly what is covered during the installation process, but it should usually cover both the equipment and the work. 

Solar Services

Momentum offers many solar services, such as system design, getting permits, applying for solar incentives, cutting down trees, fixing roofs, and installing solar panels. They are in charge of the whole process and can add extra systems, like EV charging, if asked to. 

Financing Options

On its website, Momentum Solar says that it has four plans for installing solar systems: purchase, finance, PPA, and lease. Except for buying it all at once, none of the other options require much or any money up front. Instead, they may come with different maintenance plans. Moreover, leased solar systems likely won’t qualify for government solar tax credits. 

Specials or Incentives Offered

Momentum Solar doesn't currently advertise specials or incentives, but homeowners in Massachusetts can still apply to state and federal tax incentive and rebate programs as long as the system isn't leased. Momentum also assists with applying to state and federal programs. 

In-House or Contracted Installations

Momentum Solar is in more than one state, but it has its own concierge team, employees, and technicians. The company claims to handle all parts of the installation from beginning to end and has user-friendly tools to monitor progress and energy production. 

Brands of Solar Equipment Offered

Momentum Solar doesn’t specify the exact equipment brand it uses. Different brands of solar equipment will be available in each area and project, but Momentum says it has high-efficiency, long-lasting Tier 1 solar panels from trusted manufacturers. 

Customer Reviews

Momentum Solar has been an “A+” accredited solar energy designer and contractor since 2015. Momentum customers rated their experiences 3 out of 5 stars across over 500 reviews. Most negative reviews complain of miscommunications, but others praise the company for how it handled the process from start to finish. 

Partnerships

Momentum partners with several manufacturers and in-house teams across Massachusetts and the US. Momentum Solar also works with Enphase to store energy in batteries, but this product is not yet available to people in Massachusetts.

Key Considerations When Looking for Solar Installer for Massachusetts Residents

Before signing a contract with a solar installer in Massachusetts, it's best to look at a few things first. Here are some considerations to keep in mind while vetting solar companies in Massachusetts. 

Cost of Services & Installation

Most solar installers usually offer quotes based on the price per watt. On average, the cost of solar panels in 2023 will range between $3 and $5 per watt, with most homes requiring around 5,000 kW. For example, at $4/watt, homeowners will pay $20,000 for the installation cost, not including electric bill savings and tax incentives. It’s best to consider the initial out-of-pocket cost and then factor in additional tax savings or incentives to determine if you’re getting a fair deal. 

Strong Warranty Coverage

Depending on the brand, most solar companies in Massachusetts offer warranties on both the installation and the equipment. Better warranties may cost more. Most installation warranties last anywhere from 5 to 15 years and cover how well the job was done. Equipment and performance warranties cover how the solar panels work and how they are made. Most of these warranties last up to 25 years. Most companies offer the same warranties on their equipment, but the installer will have different warranties for installation, mounting equipment, and roof leaks. 

Company Years of Experience

If possible, try to work with solar installers with several years of experience. Companies with less experience may not be as familiar with the craft and may not have as many positive results to show. Solar companies in Massachusetts with more experience will have worked with more customers and installed more solar energy systems. This will give them more experience making decisions such as how many solar panels are needed in your home and whether you should opt for monocrystalline or polycrystalline solar panels. In addition to doing research on Massachusetts solar installers, look for those who have been doing good installations for a long time. 

Solar Services Offered

If you want extra solar services, like installing technology that stores energy in batteries, you'll want to make sure your installer can meet your needs. In the same way, installing solar panels requires a lot of work with electricity, mounting, and the roof, all of which the company should have done before. Before committing to a Massachusetts solar company, learn about all its services and how they fit in with your project compared to hiring multiple companies to finish the job. 

In-House or Contracted Installations 

There are pros and cons to going with in-house or contracted solar companies. On the one hand, in-house solar installers have full control over the project through their sales team, quotes, and execution. But contracted solar installations can use any installer, which could lead to cheaper prices and more options for installers. In-house solar companies won’t have the same kind of mobility, so homeowners may be stuck with what the in-house provider offers, depending on the area. 

Solar Equipment Brands

Solar energy systems have come a long way, and now several companies offer different types of solar equipment. It's best to find out about the brand of equipment your installer uses and make sure it has a good warranty, good customer service, and has been tested and reviewed thoroughly. For example, you may prefer a more user-friendly brand over one with better financing options. Once you know what you want from your solar panel system, you should look into the brand of solar equipment your installer uses to make sure it meets your needs. 

Customer Reviews

The best solar companies in Massachusetts should have several positive customer reviews across the years they’ve been in business. It’s best to check review sites like BBB, Angi, and Trustpilot to vet their quality and customer service. Moreover, solar installers usually have a testimonial or review page on their website. You want to check for any red flags, like if a customer reports that the company never finished the job. Since customer reviews are from people who went through a similar process, you’ll get a better idea of what to expect throughout the installation process and following results.

Financing Options 

Massachusetts residents should always research the financing options available for their solar panel installation. It’s best to look for companies that have flexible options, such as requiring no money down and payment schedules that work with your budget. In the same way, after 18 months, when homeowners get their tax credits back, some financing options will change. Before committing to a solar panel installation, be sure to check with the installer to verify any financing options available to you and what the long-term cost will look like.

Solar Tax Incentives in Massachusetts

Massachusetts offers a residential renewable energy income tax credit worth 15% or $1,000 of the installation costs, whichever is less. Massachusetts residents can use this energy credit for personal income tax during that year. The state's tax policy for home and household items also says that solar panel installations and equipment directly related to solar systems are not taxed. 

Solar-powered homes in Massachusetts can also get tax breaks on their property for 20 years after installation. There is no maximum incentive for the state’s property tax exemption, and it covers 100% of eligible property taxes. 

The state government's HEAT loan program allows Massachusetts residents who want to finance to do so for free. Borrowers who qualify can get up to $25,000 with no interest to pay for energy upgrades, such as solar panels. 

On the Database of State Incentives for Renewables and Efficiency website, you can find a full list of all the solar tax incentives that are available to people in Massachusetts.
