    Sunrun designs customized solar systems in Massachusetts. The process starts with an analysis of your past electricity bills to estimate your energy needs. Next, representatives assess your roof’s unique conditions — such as shading, pitch and sun exposure — to create the optimal system design for your home.

    We also like that Sunrun’s solar lease program lets you go solar without a huge upfront investment. With leases, Sunrun owns the system, and you pay a fixed monthly fee to use it. Lease agreements typically last 25 years.

    What to consider: Some customers report dissatisfaction with contract terms. So, it’s important to review agreements closely before signing anything.

    • 100% clean energy from local sources
    • Variable and fixed payment plans

    • Referral bonuses

    CleanChoice Energy offers one of the simplest ways for Massachusetts residents to support clean energy without installing solar panels. Rather than installing panels, CleanChoice serves as an alternative energy supplier.

    The company purchases renewable energy on your behalf through grid power and renewable energy certificates (RECs). This makes it an appealing option for renters or homeowners who can’t install solar panels.

    What to consider: CleanChoice generally sources the cheapest clean energy available in your area. While this keeps rates competitive, prices can still change. Some negative reviews mention promotional rates ending sooner than expected, many customers report a positive experience.

    “Their prices are better, everything works better, and the air feels better for me and my electricity.”
    Kimberly Webster, MA
    “I chose CleanChoice because I believe in clean energy. I signed up with them and that was excellent.”
    Eva Springfield, MA
    “CleanChoice Energy gave me a better rate, so I switched to them. The process was very easy.”
    T. Milford, MA
    • How it works: Instead of getting electricity from your default utility, CleanChoice provides renewable energy sourced from wind and solar. Your local utility still manages the poles, wires and infrastructure that deliver power to your home.
    • Payment structure: Customers can choose monthly, quarterly or annual memberships. Prices may vary with market conditions. There are no cancellation or early termination fees for residential customers, so you can stop service at any time without penalty.
    “I chose CleanChoice because I believe in clean energy.”

    Switch to solar with a system built for you.

      We’ve heard from over 100,000 verified solar customers since 2018, including hundreds in Massachusetts. Here’s what to expect and what to look for when buying solar panels in the Bay State.

      Key insights

      In Massachusetts, a typical residential solar panel system costs $10,646 to $30,416, depending on the size of your system and what financial incentives you qualify for.

      Jump to insight

      The federal solar tax credit expires soon. You have until Dec. 31, 2025, to install a system and get the 30% solar tax credit.

      How to choose a solar company in Massachusetts

      Solar panels are a long-term investment — most systems last 25 years or more. That means choosing the right installer is just as important as choosing the right equipment. 

      In our experience, the best solar energy companies have a few things in common: great reviews, transparent contracts, reliable equipment and comprehensive warranties.

      Here are the key steps to finding the right fit.

      1. Research companies

      Local experience matters. Companies with a history in Massachusetts understand state-specific incentive programs, utility rules, permitting requirements and how to design systems that perform well in cold, snowy winters and warm, humid summers.

      2. Read reviews

      Look at reviews on platforms like ConsumerAffairs, Better Business Bureau and solar-specific forums to see real customer experiences. Watch out for these red flags:

      • Equipment failures that aren’t resolved quickly
      • Misleading sales tactics about costs or savings
      • Billing and contract issues

      3. Check credentials

      Solar panel installers must be licensed electricians in Massachusetts. Confirm your installer also has:

      • Insurance coverage to protect your home during installation
      • NABCEP certification (the North American Board of Certified Energy Practitioners is a respected national credential for solar installers)

      4. Compare quotes

      Some Massachusetts solar incentive programs require installers to have NABCEP certifications.

      Get at least three solar quotes to compare prices, equipment, warranties and services. Be cautious of unusually low bids — they may signal poor-quality panels, hidden fees or weak warranty coverage.

      Also, ask whether they offer extras you might want, like battery storage, an EV charger or critter guards to protect your panels.

      5. Read the fine print

      The contract should be easy to understand. If anything about payment schedules, warranties, monitoring services or system maintenance doesn’t make sense — ask for clarification. 

      Best solar companies by city

      How much does it cost to go solar in Massachusetts?

      Average solar panel costs in Massachusetts typically range between $10,646 and $30,416. The size of your solar panel system is a big factor in your total cost. It also depends on what incentives you’re eligible for, the condition of your roof and how much sunlight exposure it gets.

      NOTE: The table below doesn’t include the cost of a solar storage battery. Adding a battery to your system can increase your overall system costs by $7,000 to $18,000.

      Average solar installation cost by system size in Massachusetts

      What solar incentives are available in Massachusetts?

      The federal solar investment tax credit (ITC) is now set to expire at the end of the year, much earlier than previously scheduled. The credit was expected to drop gradually, then fully expire in 2035 — but those future step-downs have been eliminated as of July 2025.

      This means you have until Dec. 31, 2025, to install and pay for a system in order to qualify for the 30% credit.

      On the bright side, residents may take advantage of several solar incentives in Massachusetts, including state tax breaks and local rebate programs.

      Are solar panels worth it in Massachusetts?

      With rising electricity costs, more homeowners are finding solar power is worth it in Massachusetts in the long run. On average, Bay Staters with solar panels can avoid $92,499 in total utility costs over 25 years.

      We’ve heard from hundreds of residents who have already gone solar. For instance, Ronald in Groton has had solar panels since 2012. “They were paid off in four years, and since then, I have received an average of $2,400 per year in SREC payments,” he told us. 

      Homeowners with solar panels typically save $20,000 to $90,000 over 25 years.

      “I’ve driven a Chevy Bolt EV since 2019, charging from my roof solar, essentially costing me nothing and saving two tons of CO2 by not using fossil fuel,” Ronald added. 

      Similarly, Terrence in Whitinsville told us that going solar “is a no-brainer, especially if you heat and cool with electricity.” 

      But it’s not financially worth it for everyone. We suggest using the National Renewable Energy Laboratory’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house. Project Sunroof is a reliable free solar savings estimator powered by Google Earth imagery.

      FAQ

      How can I pay for solar panel installation?

      You could pay the full cost of solar panels upfront, but many choose to finance their system through a solar loan. Alternatively, you can lease solar panels or enter a power purchase agreement.

      High upfront costs are the biggest barrier for most. In general, getting a loan to pay for solar panel installation is worth it as long as the loan payment is cheaper than your existing electric bill.

      Do I need any permits before going solar in Massachusetts?

      Each municipality has its own permitting process and interconnection and net metering requirements. When beginning the permitting process in Boston, check to see if your property is in the Eversource Area Network, then see if your property is in a historic district or is a designated (or pending) landmark.

      Can I get free solar panels in Massachusetts?

      We are not aware of any legitimate programs for free solar panels in Massachusetts. However, you can lease a solar energy system with little to no upfront costs. Just look out for scams that promise free solar panels — they can cost you quite a bit of money.

      » FREE SOLAR PANELS: Are they really free?

      How do I know if my house is a good candidate for solar?

      Plenty of unshaded roof space that faces south or west is best for optimal sun exposure. Massachusetts averages 2.5 to 3.5 peak sun hours each day. However, if you have a lot of shading around your house, they might not get enough sun to power your home. It’s also smart to upgrade any old, inefficient appliances first. Solar photovoltaic (PV) technologies, more commonly known as solar panels, absorb sunlight and convert it into usable electricity.

      How does net metering work in Massachusetts?

      Net metering lets Massachusetts homeowners get credits for extra electricity their solar panels generate and feed onto the local transmission grid. The goal of net metering is to let you produce enough renewable electricity for your own home's needs, but not drastically more than what you use. Any credits that are more than a year old will expire. Here's how it works:

      1. Your home's electricity meter keeps track of both the electricity used from the local power grid and any extra electricity that your solar panels feed into it.
      2. At the end of each billing period, your utility company looks at whether your system put more electricity into the grid than you pulled out.
      3. If you put back more than you used, you get a credit toward next month's bill for the extra amount. If you used more than your system produced, you only pay the utility company for that additional amount.
      Should I replace my roof before installing solar panels?

      Consider fixing your roof before going solar if it’s more than 10 years old. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels. This will cost around $5,000 for a 19-panel setup.
