Methodology: How We Ranked the Best Solar Companies in Sterling

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


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 Sterling

Even though solar panels can help save you a decent chunk of change on energy over time, it’s important to know the upfront costs.The installation cost is just one important factor you should consider when looking into installing solar panels. How much it'll cost and how much you can save depend on things including:

  • Incentives: One thing that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that’s equal to a percentage of the project cost. You can also save money on your utility bills, which can lead to an average of $22,000 of savings over 20 years.
  • Typical energy usage: The more energy your household consumes on average and the steeper your current electricity bills are, the more likely you'll benefit from switching to solar.
  • 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 lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.
  • Your location: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.

So is a solar panel system worth it? Whether you’d like to decrease your electricity costs, carbon emissions or both, solar panels are a worthwhile investment for many Sterling homeowners.
