    What Homeowners Are Saying

    Don't just take my word for it. Here's what homeowners across Massachusetts and Rhode Island have to say about working with me.

    "Dave was extremely thorough and walked me through the whole process. Things happened quickly once National Grid approved everything, and the install was ready to go within a week! The electrician/installer was phenomenal too."

    Amanda R.

    Plymouth, MA

    "Dave and his team were fantastic. His price could not be beat as well, and I can't imagine anyone else providing better customer service or installation experience. I am now producing enough energy to completely eliminate my electricity costs!"

    Lisa A.

    Providence, RI

    "Hats off and kudos to Solar Dave and his team. Everyone from operations to the install team have been fabulous! I look at the App everyday to see how much I am over producing and how little we are using. Very impressive! If you are considering going solar, I would definitely talk with Dave."

    Questions I get all the time, answered straight.

    How long does installation take?
    Most installs are complete within 1–2 days on the roof. The full solar installation timeline in Massachusetts — from signed contract to system turned on — is typically 6–12 weeks, depending on how fast your town issues permits and how quickly your utility (National Grid or Eversource) processes interconnection. I manage all of that for you.
    Is solar worth it in Massachusetts?
    For most South Shore homeowners, yes — and I'll tell you honestly if it's not. Massachusetts has some of the best solar economics in the country: high electricity rates, the federal 30% tax credit, a state income tax credit, and the SMART program. Most homes I work with see payback in 6–9 years and lifetime savings well into six figures. I break this down in detail in my guide — Is Solar Worth It in Massachusetts in 2026?
    How much can I save?
    It depends on your roof, your usage, and your rate — which is exactly why I look at your actual numbers before quoting anything. A typical South Shore system I design offsets 80–100% of a home's electricity use. The Scituate install shown above saves roughly $5,100 a year and is projected to save over $157,000 over the life of the system. Learn how to calculate your solar savings.
    Will solar increase the value of my home?
    Yes, consistently. Massachusetts buyers are increasingly familiar with solar, and a paid-off system is a real selling point. Studies show solar adds more to home value than it costs in most markets — and Massachusetts is one of the stronger ones. Read more about if do solar panels increase home value in Massachusetts.
    Do I need to pay upfront for solar?
    No. Most of my customers finance through MassSave HEAT Loan programs or dedicated solar lenders with little to no money down. In many cases, your monthly loan payment is lower than what you're currently paying your utility. I'll show you the comparison before you decide anything. Explore your solar financing options.
    What incentives are available?
    Massachusetts has some of the best solar incentives in the country. The main ones are: the Massachusetts state income tax credit (15%, up to $1,000), the SMART program — a per-kWh payment (~$0.03/kWh) from your utility that runs for 10 years, net metering credits on your electric bill worth around $0.34/kWh, and ConnectedSolutions — a demand-response program that can pay $1,000 or more per year for battery storage systems. Some towns have additional rebates too. Incentives change, so I walk every homeowner through exactly what's current and what applies to their situation. I cover all of these in detail here — Massachusetts solar incentives guide
    How do I know if my home is a good fit for solar?
    The main factors are roof age and condition, roof orientation (south-facing is best, but east and west work too), shading from trees or neighboring structures, and your average monthly electric usage. I do a full assessment before recommending anything — and I'll tell you straight if it's not a good fit. Find out does my roof qualify for solar.
    How much does solar cost in Massachusetts?
    A typical residential system on the South Shore runs between $25,000 and $55,000 before incentives, depending on how much power your home uses and your roof layout. After the 30% federal tax credit alone, that drops to $17,500–$38,500. I'll give you a specific number for your home — no ranges, no estimates. Learn more about solar panel costs in Massachusetts.
    Will solar work with shade or trees?
    Sometimes, sometimes not. Partial shade reduces production, but it doesn't automatically rule out solar. I use Enphase microinverters on most installs, which means each panel operates independently — so one shaded panel doesn't drag down your whole system. I'll look at your specific shading situation and tell you what to expect. Read more about solar with shade and trees.
    Should I replace my roof before going solar?
    If your roof has 7 or more years of life left, you probably don't need to replace it first. If it's getting close to the end, it's worth doing before the panels go on — not after. I check roof condition as part of every site assessment and I'll flag it if it's something we need to talk about before moving forward.
