Methodology: How We Ranked the Best Solar Companies in Marlborough

EcoWatch's solar experts analyzed each solar company in Marlborough based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Marlborough


Below are some the criteria we examined specifically for Massachusetts solar companies

  • Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
  • Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
  • Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
  • Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
  • Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
  • Availability (10%): The bigger the service area, the higher the company will score.
  • Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
  • Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.

The Cost and Benefits of Solar in Marlborough

The cost of installing a solar panel system has dropped immensely over the past few years, but it's still a significant investment for most homeowners. The overall price and potential savings vary depending on a few important factors such as:

  • Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 30% of the project cost. Your state and even local utility companies may also have various incentives that you can use. Plus, you can save about $21,000 over 20 years on your utility bills, before factoring in incentives.
  • The type and model of solar panels you want: More efficient models are more costly, so that will influence your budget for your solar project.
  • How much power your household needs: If your home regularly uses a lot of energy, you'll see more savings from switching to solar.
  • How much energy costs for you: The typical household in Marlborough shells out around $970 a year on energy alone, so you could be looking at that much in savings.

Thanks to the cost of solar panels being lower than before as well as local and federal solar incentives, they are a cost-effective investment for most homeowners.

Solar Incentives in Marlborough

If you're thinking about switching to solar power, a number of government incentives and tax credits can immensely reduce your project costs and expedite the return on your investment. You can qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar panel system. You can also possibly pair the ITC with other local incentives. In our article on solar incentives, you can find out about the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in Marlborough

There are many reasons to trade traditional energy for solar power, like saving on utility bills and helping to lower your carbon footprint. But how much can installing solar panels actually help the environment? Something that can severely affect your carbon footprint is how long your commute is and how much you drive generally. If you go solar and drive an electric car, you can vastly cut back on your carbon dioxide emissions by charging your car at home. When you go solar, your carbon footprint can be cut by about 40 pounds each year. If you care about the environment, you'll likely get that there are many benefits of adopting solar energy other than just saving money on electricity. You can also help protect the environment, which some would argue is more valuable.

EcoWatch's Marlborough, MA Solar Company Rankings FAQs

What is the top solar panel company in Marlborough?

In Marlborough, United Better Homes is the best local solar company. Our team of experts rates it 5.00 stars, so it's a great choice if you're looking to install solar panels on your roof.

What are the pros and cons of solar power?

The greatest advantages of solar power are that it can decrease or, in some cases, totally eradicate your electricity bills, improve the value of your home and cut back on your carbon footprint. The greatest disadvantages are that solar panels can be expensive to install, you may not save as much if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.

How long does it take for solar to pay for itself?

The average payback period for solar panel installation is about 9.5 years, but the exact period varies by local electricity costs, incentives and net metering programs.

What are the different kinds of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels are less expensive but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can't, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and desired energy output.
