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

For many people considering switching to solar, the decision of which solar company to hire depends on total costs.The cost and possible savings vary depending on some key factors such as:

  • The kind of solar panel system you can purchase: This is dependent on how much you’re willing to spend upfront.
  • Incentives: Something that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save on your utility bills, which can give you an average of $22,000 of savings over 20 years.
  • Average daily sunlight: Since Holliston gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which affects how much your electricity bills will be.
  • Typical energy usage: The more energy your household consumes on average and the higher your current power bills are, the more benefits you’ll see from switching to solar.

So is installing solar panels worth it? Whether you want to decrease your electricity costs, carbon dioxide emissions or both, solar panels are a worthwhile investment for many Holliston homeowners.

Solar Incentives in Holliston

Since solar power is a cleaner source of energy than fossil fuels, there are quite a few government incentives available to encourage people to make the switch.Regardless of where you live, you can take advantage of the federal Solar Investment Tax Credit (ITC), which lets you claim 0 of how much your solar project cost when you file taxes, lowering the amount of taxes you owe that year. In addition, there may be some local incentives that stack with the ITC too. Check out our article on solar incentives to see what incentives you can benefit from.

Environmental Impact of Switching to Solar in Holliston

One of the most compelling reasons to switch to solar energy is to reduce your reliance on traditional energy sources like burning fossil fuels, which are destructive for the environment.You may be wondering – how much does making the switch do for the planet anyway? In a city like Holliston where energy use is somewhat high, making the switch to solar power is a good idea for people who want to do their part for the environment.Since solar panels don’t release greenhouse gas emissions into the atmosphere when producing electricity, they’re a good swap for traditional energy sources. In fact, you could reduce your carbon dioxide emissions by about 40 pounds each year. As you can see, investing in solar has so many other rewards apart from saving money. One of the main ones is that you can help save the Earth too.

EcoWatch's Holliston, MA Solar Company Rankings FAQs

What is the most reputable solar panel installation company in Holliston?

In Holliston, SunPower by BlueSel Home Solar is the best local solar company. Our team of experts rates it 3.00 stars, so it's a solid choice if you're planning on installing solar panels on your roof.

What are the pros and cons of solar power?

The advantages of solar power are that it can lower or, for some, totally cut your electricity bills, raise your home’s value and lower your carbon footprint. The biggest disadvantages are that solar panels can be costly to install, you may not see as many savings if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.

Is it worth putting solar panels on my home?

Solar panels can be a fruitful 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 types of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels cost less 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, the layout of your roof and desired energy output.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
