Sunpower Review

1. SunPower

SunPower has been around for almost three decades, and in that time, the company has distinguished itself as a leader in the solar energy industry. Despite being a national company, SunPower is an excellent choice for Massachusetts residents, with Massachusetts’ outstanding solar incentives program helping to offset the high cost of SunPower’s premium panels.

Pros

  • Industry-leading efficiency
  • In-house installations in many cases
  • Excellent customer service
  • 30 years in the business

Cons

  • More expensive than most solar companies
  • Not strictly a Massachusetts business

Company Profile: Cost, Warranty, & Services

SunPower panels are among the most expensive in the country, making the upfront costs seemingly prohibitive for some Massachusetts residents. However, the company offers an outstanding selection of solar services and several financing options, making it the best overall option and an accessible one despite its high costs.

Average Cost

SunPower customers pay a premium for access to the company’s state-of-the-art solar systems and high-quality installation services. The price can vary quite a lot, but the typical cost is well above average.

Warranty

SunPower offers a generous 25-year warranty on all its solar panels and workmanship. It also covers power production for 25 years, and it offers a warranty for roof leaks, which is a rarity in the industry.

Solar Service

SunPower is a full-service solar company offering solar panels, solar batteries, electric vehicle (EV) chargers, and solar monitoring.

Financing Options

SunPower has several financing options available. Customers can choose to pay in cash, via traditional financing, or opt for a solar lease, solar loan, or power purchase agreement (PPA).

Specials or Incentives Offered

As of this writing, SunPower offers a $100 reward to any customer who refers a friend or family member who signs up for an in-house consultation.

In-House or Contracted Installations

SunPower used to contract installations to local businesses but has recently started conducting in-house installations.

Brands of Solar Equipment Offered

SunPower stocks Maxeon panels that come with their own microinverters.

Partnerships

SunPower is accredited by the Better Business Bureau (BBB) and is partnered with several local Massachusetts companies that carry and install its panels.

2. Green Power Energy

Green Power Energy is a relative newcomer to the solar energy business. The company was founded in 2012 and brought a unique, education-first approach to installing solar panels throughout Massachusetts. The company’s prices are fair, and it offers many standard solar services.

Pros

  • Laid back, knowledgeable sales team
  • Focus on education
  • Top-notch customer service
  • Technicians have regional knowledge

Cons

  • A young company without many reviews online

Company Profile: Cost, Warranty, & Services

Green Power Energy stocks many common solar panel brands and offers more reasonable prices than SunPower. The company also provides access to several flexible payment options that can help Massachusetts residents invest in renewable energy without breaking the bank.

Average Cost

The average cost of Green Power Energy solar panels is between $10,000 and $25,000, right in line with the overall average across the state.

Warranty

Green Power Energy offers a limited 25-year warranty that covers hardware, but the company’s website doesn’t mention any performance guarantees.

Solar Services

Green Power Energy carries solar panels, batteries, innovative solar roof shingles, and EV chargers.

Financing Options

The company has excellent financing options, including $0 down loans and leases. It also accepts cash purchases.

Specials or Incentives Offered

As of this writing, Green Power Energy is offering $1,000 to anyone who recommends a new customer that ultimately signs up with the company.

In-House or Contracted Installations

Green Power Energy’s installation process is handled entirely in-house.

Brands of Solar Equipment Offered

The company carries Generac, Panasonic, Q Cells, Silfab, REC, JinkoSolar, Solaria panels, and Tesla.

Partnerships

Green Power Energy has several industry partners, including IronRidge Racking and Generac Power systems. Its installers are also certified by the North American Board of Certified Electrical Practitioners (NABCEP).

3. Trinity Solar

Trinity Solar has been in the solar business since 2014 but has more than 30 years of experience working on homes in the northeastern U.S. In less than ten years, Trinity Solar has installed over 80,000 solar systems for northeastern homeowners, plenty of whom live in Massachusetts. The company has a solid selection of solar services and states that maintaining a local focus is one of its guiding principles.

Pros

  • Excellent northeastern solar company
  • Tons of financing options
  • Offers upgrades
  • Good customer service

Cons

  • Warranty isn’t as comprehensive as the competition
  • Information is hard to get because the company is privately-owned

Company Profile: Cost, Warranty, & Services

Trinity Solar is a family-owned solar business, which ultimately means it provides excellent customer service at a higher price than the competition.

Average Cost

Trinity Solar doesn’t publish pricing information on its website, preferring to deal directly with prospective customers on a case-by-case basis. This makes some sense but makes it difficult to estimate costs without contacting the company for a free quote. However, its prices usually fall around average.

Warranty

One weakness Trinity Solar has is its warranty. The company offers a 25-year limited warranty on equipment, but the workmanship is only guaranteed for five years and performance for a paltry two years.

Solar Services

The company installs solar panels, EV chargers, and solar batteries.

Financing Options

Trinity Solar customers can pay for their panels in cash or choose to use a loan or PPA.

Specials or Incentives Offered

Trinity Solar offers a $250 incentive for every customer you refer to the company.

In-House or Contracted Installations

Trinity Solar reports that most of its installations are done in-house, although it does keep subcontractors nearby to help speed things up when the schedule gets full.

Brands of Solar Equipment Offered

Trinity Solar carries solar equipment from many major brands, including Generac, SolarEdge, Q Cells, Enphase, and Tesla Powerwall batteries.

Partnerships

Trinity Solar partners with many local charities and has a business relationship with the solar racking company EcoFasten.

4. SunRun

SunRun is a national solar installation company, but what you lose in local flair by going with SunRun, you gain in niceties like leasing, affordability, flexibility, and financing options. The company also offers top-of-the-line solar energy solutions through its Brightbox system, a whole-home approach to storing and monitoring your energy usage. Unfortunately, SunRun warranties are not competitive with other brands, with people who opt to purchase their panels being stuck with just the manufacturer’s warranty.

Pros

  • Excellent track record
  • Stability as a large business
  • Access to high-quality equipment from companies like LG and Tesla

Cons

  • Warranties don’t cover purchased panels
  • Sales team can be pushy

Company Profile: Cost, Warranty, & Services

SunRun is somewhat unique among solar panel companies in that it heavily incentivizes leasing panels over purchasing them. SunRun’s prices are in line with the Massachusetts average, but customers who purchase panels from SunRun are stuck with the manufacturer’s warranty and are responsible for maintaining the panels themselves.

Average Cost

SunRun estimates that Massachusetts residents pay an average of $15,000 for a 4 kW system and $29,000 for an 8 kW system before the federal investment tax credit (ITC). This is around average.

Warranty

SunRun’s warranties are more complicated than most solar companies, largely thanks to the distinction it makes between purchased and leased panels. SunRun does not provide an additional warranty on top of the manufacturer’s warranty, so customers who purchase panels need to familiarize themselves with each brand’s warranties before committing.

Leasing panels from SunRun is a much more affordable proposition since leased panels are covered for repairs and replacements by SunRun for up to 25 years. However, leases tend to save you less in the long run.

Solar Services

SunRun offers solar panel installation, battery backup installation, solar panel system monitoring, and EV charger installation.

Financing Options

SunRun pushes its customers towards its leasing options, but customers who prefer to purchase solar panels can pay in cash or use in-house financing with no money down if they qualify.

Customers who choose to lease panels from SunRun have the option of leasing them monthly or paying the full lease from the start. Monthly leases require customers to pay to purchase the energy their panels generate, although SunRun guarantees that the costs will not exceed what you would pay your utility company.

The full lease option costs more than the monthly lease option since you have to pay the entire cost of the 25-year lease upfront. This option is cheaper than buying the panels outright and affords you the benefit of SunRun’s maintenance and performance guarantees.

Specials or Incentives Offered

SunRun offers a $1,000 reward for anyone who refers friends or family. The person you refer must sign up for solar service with SunRun for you to receive the reward.

In-House or Contracted Installations

SunRun uses a specialized proprietary software package to survey and design your solar system before installing it. However, it often outsources installations.

Brands of Solar Equipment Offered

SunRun used LG panels until early 2022 when LG ceased manufacturing solar panels. The company has not disclosed who its other suppliers are, although it has said that all its panels are tier one, meaning they’re high-quality solar products from well-established companies. SunRun offers storage solutions via Tesla Powerwall or LG Chem lithium-ion batteries.

Partnerships

SunRun has a high-profile partnership with Ford to install the company’s F-150 Lightning EV charger. SunRun also partners with CHANEL to bring affordable clean energy to low-income families in California.

5. Momentum Solar

Momentum Solar is a large solar energy company with a national footprint. It has been providing solar services to Massachusetts residents for ten years. The company takes a straightforward approach to solar energy, offering basic services backed by a generous warranty. It also makes customer service a priority with its concierge service structure, which guarantees you only interact with one person throughout your entire solar project, which is great for a large company.

If you’re looking for a solar company that offers tons of options, Momentum Solar isn’t the best choice. But if you want a dependable company that handles installation in-house and provides basic services at reasonable prices, it’s worth a look.

Pros

  • Excellent warranty
  • Superlative customer service
  • Will handle local permits for you

Cons

  • Limited product selection

Company Profile: Cost, Warranty, & Services

Below, we’ll discuss some of the most important factors you should consider before hiring Momentum Solar for your solar project.

Average Cost

Without official pricing information on the Momentum Solar website, we can only estimate the average cost based on customer reviews. Most reviews suggest that Momentum prices reflect the local Massachusetts average, putting a conservative estimate of the average cost around $20,000 before the ITC is considered.

Warranty

Momentum Solar separates itself from the pack by offering one of the best warranties of any solar company we’ve seen in Massachusetts or elsewhere. The company backs all its installations with a comprehensive 25-year warranty covering equipment and craftsmanship.

Solar Services

Unfortunately, Momentum Solar’s services aren’t very impressive. The company offers basic panel installation and battery backups, but not much else.

Financing Options

Somewhat surprising in light of its limited product lineup, Momentum Solar offers several convenient financing options. Customers can purchase their panels in cash or choose to finance them with a solar loan, solar lease, or PPA.

Specials or Incentives Offered

Customers can take advantage of the Momentum Family Referral Program to earn money for referring friends and family members, although the website doesn’t specify the details.

In-House or Contracted Installations

Momentum Solar does its own installations in-house, which is somewhat of a rarity for private solar companies of comparable size.

Brands of Solar Equipment Offered

Momentum Solar Doesn’t specify what brands it uses for its panels, although it does say it only uses Tier 1 panels. The company sources its microinverters and batteries from Enphase. Customers can choose either the 3.36 kWh Encharge 3 or the larger 10.08 kWh Encharge 10 for their energy storage solution.

Partnerships

Momentum Solar has a strong working relationship with industry giant Enphase for its microinverters and battery backups. Its installers are also NABCEP-certified.

6. Palmetto Solar

Far from being a local Massachusetts rooftop solar company, Palmetto Solar is one of the ten largest solar companies in the country. It’s known for being a flexible company, offering several financing options, an assortment of top-quality products, and unique ethical guarantees related to the solar supply chain. Palmetto Solar’s prices are competitive based on value provided, but they are still on the high side. However, many Palmetto customers are willing to foot the higher bill to support the company, citing its strong morals and excellent customer service.

Pros

  • Ethical sourcing of equipment
  • Top-of-the-line panels
  • Easy to use monitoring app

Cons

  • Underwhelming workmanship warranty
  • Paid service for monitoring and maintenance

Company Profile: Cost, Warranty, & Services

Below are some of the aspects of Palmetto you should think about if you’re considering hiring the company.

Average Cost

Palmetto doesn’t publish pricing information on its website, although customer reviews indicate that the cost of Palmetto solar panels is average to slightly above-average. This puts the average cost around $20,000 for the average Massachusetts home. The company does offer a handy cost estimator for several simple array designs, making it easy to get a quick and dirty estimate before you request a free estimate.

Warranty

Palmetto Solar’s panels are covered under a 25-year equipment warranty, and the inverters it uses come with a 12-year warranty if you go with SolarEdge and a 25-year warranty if you opt for Enphase inverters. The company also stands behind its installations with a 10-year workmanship warranty that includes five years’ worth of protection against roof punctures.

Solar Services

Palmetto Solar offers solar panels, batteries, monitoring, and maintenance, as well as customized survey and design services for new customers.

Financing Options

Palmetto customers can choose to pay cash for their panels or choose to lease them. The company also offers PPA for people who prefer not to own their panels.

Specials or Incentives Offered

As of this writing, Palmetto Solar has a refer-a-friend program that earns you $100 for every customer you refer that signs up for solar through Palmetto.

In-House or Contracted Installations

The company’s installations are all done in-house, so you don’t have to worry about juggling multiple contacts or chasing down hard-to-reach subcontractors.

Brands of Solar Equipment Offered

Palmetto Solar doesn’t have an exclusive deal with any equipment manufacturer, preferring to use the best and most cost-effective equipment available. Currently, that means using panels from Q Cells, inverters from SolarEdge and Enphase, and batteries from Sonnen.

Partnerships

Late in 2021, Palmetto announced a partnership with Exelon Utilities for an initiative to bring potential solar customers actionable data that may help speed up solar adoption. The company offers its Mapdwell Solar API to Exelon so that Exelon’s 10 million customers can access detailed information about their property’s solar compatibility.

7. Boston Solar

Boston Solar is the number one residential solar installer based in Massachusetts. The company has logged an impressive 5,000 residential solar installations in its 11 years in the industry and maintains an impressive A+ rating from the BBB. The company is the epitome of a small, local installer and offers the customer service and guarantees you expect from a regional business. The company stands behind its installations with a 10-year performance guarantee and offers high-quality workmanship.

Pros

  • Local Massachusetts company
  • Stellar customer service reputation
  • Exceptional production guarantee

Cons

  • A bit expensive
  • Fewer equipment options than most

Company Profile: Cost, Warranty, & Services

As a comparatively small solar business, Boston Solar can’t compete with some of the larger companies when it comes to cost. What they offer instead is high-quality service from experienced technicians and unmatched performance assurances. The company also brings a regional awareness that non-native companies lack. Boston Solar services communities across the Bay State, including Woburn, North Andover, Waltham, Worcester, Marlborough, and, of course, Boston.

Average Cost

The average cost of solar services from Boston Solar is slightly higher than the overall Massachusetts average, coming in at around $20,000–$23,000 in most cases.

Warranty

Boston Solar offers the best warranties in New England, including a 10-year production guarantee that offers to make up the difference by paying customers for underperforming systems. The company also offers standard 25-year warranties on its panels and inverters.

Solar Services

Boston Solar offers solar panel installations, solar energy monitoring, battery backups for storing energy, racking, inverters, critter guards for protection against chipmunks and other animals, and snow guards that prevent your solar system from incurring damage during the winter.

Financing Options

Boston Solar accepts cash, and offers financing through Massachusetts Solar Loans and Sungage Financial. Unfortunately, they don’t offer PPAs.

Specials or Incentives Offered

Boston Solar offers $25 for any referrals that schedule a free consultation and $500 for any referrals that have a solar system installed.

In-House or Contracted Installations

Boston Solar’s website is unclear as to whether the installation is done by an in-house team or contracted out. It only says that the installation is performed by a team of solar installation experts and a licensed electrician.

Brands of Solar Equipment Offered

The Boston Solar website indicates that the company uses LG solar panels, although with LG ceasing production early in 2022, it is unclear what company will supply panels in the future. The company offers Encharge 3, Encharge 10, and Tesla Powerwall battery storage.

Partnerships

Boston Solar made headlines by announcing its partnership with the Boston Red Sox MLB franchise to bring awareness to solar technology across Massachusetts.

Final Verdict: The Best Solar Company in Massachusetts

For our money, SunPower is the best overall solar company in Massachusetts. The company brings its considerable reputation for providing outstanding solar services to the Bay State, performing high-quality installations in-house, and offering industry-leading warranties on all its products. That said, SunPower is a premium solar company, so don’t expect to get bargain basement prices.

If you prefer a more Massachusetts-focused company, we believe Green Power Energy is tough to beat. The company only services properties in the northeast and is quickly becoming a regional leader in providing affordable solar installations.

Factors to Consider When Choosing The Best Solar Company in Massachusetts

If you’re still unsure which Massachusetts solar company is right for you, it might help to consider different aspects of solar service in general. Below, we break down the most important factors you need to think about before going solar.

Cost of Services & Installation

Most people know that solar is expensive, but they don’t realize that costs can vary substantially between different companies. For example, a company like SunPower focuses on offering the highest-quality solar panels and equipment, making its prices much higher than other companies on average. On the other hand, a smaller company like Green Power Energy may be more affordable, although you’ll have to settle for a smaller selection.

You also need to consider the long-term benefits of switching to solar power. Even if the upfront cost of purchasing solar panels seems excessive, realize that you’ll save money on your electric bill for the next 20–30 years. Additionally, solar panels offer excellent ROIs and raise the value of your home, making them an excellent investment if you’re considering moving in the future.

Equipment and Damages Warranty

Many potential solar customers don’t pay enough attention to the warranties offered on their solar systems. Some companies offer comprehensive 25-year warranties that cover equipment, labor, and performance, while others only offer minimal short-term warranties and leave the rest up to whatever warranty the manufacturer supplies.

Warranties are especially important for Bay Staters who live along the coast or in the northern parts of the state, where they must contend with corrosive coastal conditions and harsh, icy winters, respectively.

Solar Services Offered

Not all solar companies offer the same services, making it important to find a solar provider that offers the products and features you’re looking for. Virtually every solar installer will offer panels and batteries, but more specialized services like EV chargers and in-depth solar monitoring aren’t always available. Make sure you know what you want before you start shopping since it will be much easier to filter your options with a clear picture of what you’re looking for in your head.

Financing Options

Financing options are related to the cost of services and installation but offer an opportunity to people who can’t afford to purchase their panels in cash. Many solar companies offer in-house financing, and some provide more options like solar leases and loans. The most complicated financing option is a PPA, which entails a solar company installing panels on your home and selling you the energy they generate.

The rate you’re charged under a PPA is often significantly lower than the rate you’d pay for electricity from a local utility company, making the agreement a win-win situation for both you and your solar provider. Leases and PPAs tend to be the cheapest upfront but end up saving you the least amount of money over time.

Do They Contract Installation?

A subtle detail about solar installations that many new solar customers miss is whether the company installs your panels in-house or hires an external company to do it. It might not seem like a big deal, and oftentimes it’s not, but some subcontracted solar installations suffer from customer service issues. It can be unclear who to call if your installation runs into a problem and workmanship disputes are sometimes more complicated when another company is involved.

If you have the option to choose a company that handles its installations in-house — all else being equal — you should choose them over a company that contracts its installations out to a third party.

Brands of Solar Equipment Offered

As the solar industry evolves and panels become more efficient, the differences between brands become less important. However, the current consensus is that some brands — most notably Maxeon and Tesla — are ahead of the field in terms of energy efficiency. Part of the high price SunPower solar systems go for is due to the high-quality Maxeon panels the company uses. Similarly, LG Chem and Tesla lithium-ion batteries are the best options for storing solar power and fetch proportionally higher prices.

If you want a simple answer and don’t want to do tons of brand research, here’s the bottom line: go with a company that uses Tier 1 panels. Most Tier 1 panels are extremely high-quality options these days, and while you won’t know who manufactures your panels before they’re installed, you can rest easy knowing they’ll be more than good enough to supply your home with clean energy for years to come.

Average Online Rating and Customer Reviews

Before you sign on the dotted line with any solar company, you should take some time to read customer reviews online. Hearing from real customers who have both positive and negative things to say about a company is the best way to get a feel for what it will be like as a customer. Reviews on the internet aren’t a one-to-one substitute for firsthand accounts from friends and family, but they offer insight that you won’t get from the promotional material a company posts on its website.

Industry Partnerships

The solar industry is one of the fastest growing businesses in the United States, and companies are constantly looking for opportunities to distinguish themselves from the ever-growing list of solar providers. One way to do that is by forming partnerships with related businesses. Many solar companies strike deals with racking companies, roofers, battery suppliers, and general contractors to expand their influence. A company without many partnerships may be perfectly good, but a tight network shows that a company has staying power and will likely be around for many years, giving you some peace of mind.

Size of Company

Company size is a double-edged sword. Large companies can usually afford to charge lower prices and offer more service options but can’t provide the same level of personal attention that you get from a smaller company. Conversely, smaller businesses excel at customer service and personal relationships, but you’ll have to pay more for it.

The bottom line is that both large and small solar companies can be the right choice for you depending on what you value. If you want the most affordable panels that are backed by an industry giant, choosing a large national provider like SunPower is an easy choice. Instead, if you value fast response times and personalized attention, a smaller company like Green Power Energy might be better for you.

FAQs

What is the most reputable company in Massachusetts?

We believe that SunPower is the most reputable solar company in Massachusetts. SunPower is a titan of the solar industry for a reason, and it has one of the longest track records of outstanding service of any solar company that operates in the Bay State.

Is solar panel installation worth it in MA?

Yes! Many people wonder if installing solar panels in Massachusetts is worth it due to the high latitude across much of the state. While that is a factor that determines how effective your solar panels will be at converting the sun’s energy into electricity, it might not be as important as you think at relatively modest northern latitudes.

More importantly, Massachusetts offers some of the best solar incentives of any state in the country, making it more affordable to install solar panels in Massachusetts than in most places. Massachusetts solar purchases are exempt from sales tax, meaning you don’t have to pay the state’s nominal 6.25% sales tax for any solar purchases.

Massachusetts residents can also take advantage of the state’s Solar Massachusetts Renewable Target (SMART) program, which pays solar customers for every kWh their solar systems generate for ten years.

Finally, Massachusetts has one of the best net-metering programs in the country, offering homeowners with solar panels ongoing compensation for every kWh they generate above their home’s usage. Homeowners can sell their energy back to their utility company.

How much does solar installation in Massachusetts cost?

The system cost in MA can vary quite a lot based on many factors, including the equipment brands you install, the contractor you choose, and the size of the system you need. The average cost per watt in Massachusetts is around $3, putting the typical 6.5-kW system required in the area at around $19,000, or $14,000 after considering the ITC.

What is the lifespan of solar panels?

Most solar panels last for between 20 and 30 years. The lifespan of your solar panels depends on how well you maintain them and your local climate. Panels may not last as long in windy environments like MA, where they’re susceptible to falling debris and direct wind damage. Solar panels are also prone to animal damage — especially from birds and squirrels — and winter weather. It is not a coincidence that the maximum warranty offered by most solar companies is 25 years.

Can you get solar panels installed for free in Massachusetts?

No, but it is possible to lower the cost by taking advantage of state and federal incentive programs. Some solar companies advertise free panels, but it’s usually just a lease or a PPA designed to look more appealing. However, virtually all solar companies offer free quotes.

What is the ROI for solar panel installation in MA?

Massachusetts solar systems offer excellent ROI, with most systems returning several times their upfront cost over their lifespan. Keep in mind that solar panels also increase the value of your home, so the ROI must include this factor in addition to the money you save by generating your own power.

The median sale price for single-family homes in Massachusetts in 2021 was around $500,000, and Zillow estimates that solar panels add 4.1% to the value of your home on average. That means that installing solar panels on the average Massachusetts home adds approximately $20,000 to the value, making it easy to see why they’re an excellent investment with an outstanding ROI.

Is there a solar tax credit in Massachusetts?

Massachusetts residents are eligible for the federal tax credit, but the state doesn’t offer its own tax rebate. In lieu of a state tax credit, Massachusetts does not subject solar purchases to sales tax. Residents can also take advantage of the SMART program and Massachusetts’ excellent net-metering policies to receive direct compensation for the solar energy they generate.
