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

When deciding on a solar company, most homeowners or business owners care about the costs the most.The cost of solar and the savings it generates vary depending on a few key factors such as:

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 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.
  • How much energy you use: If your family uses a lot of energy, you'll benefit more from installing solar panels.
  • Your income and budget: This determines what kind of solar panels you can get.
  • Your location: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.

So is buying solar panels worth it? Whether you’d like to decrease your energy bills, greenhouse gas emissions or both, solar panels are a solid investment for many Marlborough homeowners.

EcoWatch's Marlborough, CT Solar Company Rankings FAQs

Which solar power company is the best near me?

The highest-rated local solar company in Marlborough is SunRun Solar, with a rating of 3.00 stars.

Are solar panels really good for the environment?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Solar panel manufacturing requires a lot of energy as well. The energy payback period is about 1 to 4 years.

How long does it take to see a return on your investment after buying solar panels?

The average payback period for solar panel installation is about 11.4 years, but the exact period varies depending on local electricity costs, incentives and net metering programs.

When is the best time of year to install solar panels?

Although summer is the most common time people install solar panels, the best time is actually winter. You can save money since there's decreased demand during the winter months, and it allows you to be up and running with solar for the more expensive power bills you may get during the summer.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
