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 Connecticut 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

We get that for lots of homeowners, the choice to invest in solar depends on installation costs.There are several factors you should take into consideration when determining costs and your potential savings, including:

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 0 of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Excluding incentives, you can save an average of $22,000 over the first 20 years with your solar system, too.
  • System size and type: Some models are more costly than others, so the one you decide on can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
  • The amount of sunlight your roof gets: If your roof doesn’t see much direct sunlight, your solar panel system won’t be able to generate as much energy, which will leave you with lower savings on electricity bills than a house with a roof that gets plenty of sunlight.
  • Electricity consumption: The average home in Marlborough doesn’t use much energy, and as a result may not see as many savings on their power bills.

Thanks to solar panels now being cheaper than ever as well as local and federal solar incentives, they are a cost-effective investment for many homeowners.

Environmental Impact of Switching to Solar in Marlborough

Making the switch to solar power is a profound way to do what you can for a more eco-friendly future.Something many people might be wondering about is how much can they really help save the environment by switching to solar power anyway? The average person has a considerable carbon footprint. Between their car, which produces over 10,000 pounds of carbon dioxide emissions a year, and electricity for their home, it can be overwhelming to think about what to do. Using solar power is a practical thing you can do to help.Since solar panels don’t release CO2 emissions into the atmosphere when generating electricity, they’re a good trade for traditional energy sources. In fact, you could reduce your carbon dioxide emissions by about 40 pounds each year. As you can see, trading traditional energy for solar has so many other perks outside of saving money. One of the most important ones is that you can help save the environment too.

What are some of the main advantages and disadvantages of going solar?

What is the efficiency of solar panels?
