Methodology: How We Ranked the Best Solar Companies in Old Greenwich

EcoWatch's solar experts analyzed each solar company in Old Greenwich 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 Old Greenwich


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 Old Greenwich

For many people considering switching to solar, the decision of which solar company to go with comes down to pricing.There are quite a few factors you should consider when determining how much it will cost and how much you can save, such as:

  • The amount of sunlight your area gets: Because of Old Greenwich’s high amount of average daily sunlight, you should be able to save a decent amount on your electric bills.
  • The kind of solar panel system you can afford: This depends on what your budget is.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 0 of your total installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Not including incentives, you can save an average of $23,000 over the first 20 years with your solar system, too.
  • Your household's power bills: Because of fairly high monthly electricity bills in Old Greenwich, you could save about $1,800 a year with solar.

Even though a solar panel system costs a good chunk of money upfront, it can save you much more over time. The question of how much, though, depends on several factors, such as the size of your solar panel system and your current power bills.

Environmental Impact of Switching to Solar in Old Greenwich

One of the most compelling reasons to use solar power is to reduce your reliance on traditional energy sources like burning fossil fuels, which are hazardous for the environment.You may be wondering – how much does going solar do for the planet anyway? One thing to keep in mind is your overall carbon footprint. For example, if you spend a lot of time on the road and have an electric vehicle, you can install solar panels on your home to power your EV and therefore help offset your carbon emissions.Though solar panel manufacturing emits carbon dioxide, the panels make up for it by considerably decreasing the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In Old Greenwich, you can reduce your carbon footprint by 40 pounds a year with solar panels. As you can see, using solar power has so many other rewards beyond saving money. One of the most important ones is that you can help save the Earth too.

What are the best and worst things about solar power?
