Methodology: How We Ranked the Best Solar Companies in Holliston

EcoWatch's solar experts analyzed each solar company in Holliston 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 Holliston


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 Holliston

We understand that for most homeowners, the choice to invest in solar hinges on installation costs.Some key things that affect the upfront cost and potential savings over time include:

  • Choice of solar panels: The kind of solar panels you are interested in getting will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 0 of the cost of installing your solar panel system from your federal taxes. Additionally, not including incentives, you can save about $22,000 over 20 years on your energy bills.
  • The amount of sunlight your roof gets: This, plus your roof configuration, affects affect how much power your solar panels can produce.
  • Electricity consumption: The average household in Holliston doesn’t use much energy, and as a result may not see as many savings on their power bills.

Although a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on a number of factors, including the angle of your roof and incentives.

EcoWatch's Holliston, MA Solar Company Rankings FAQs

Which solar power company is the best near me?

The best local solar company in Holliston is SunPower by BlueSel Home Solar, with a rating of 3.00 stars.

What are the pros and cons of solar power?

A few of the biggest pros are that it decreases your power bills, it’s good for the environment, and it gives you a decent return on your investment (ROI). The most notable cons are that solar panels don’t produce electricity at night, there is a high upfront cost and solar panels can look clunky on your roof.

Are solar panels worth it?

Solar panels can be a great investment for a majority of homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your electricity bills are already pretty low, solar panels might not be for you.

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, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and desired energy output.
