Methodology: How We Ranked the Best Solar Companies in Fairfield

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


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 Fairfield

The cost of putting up a solar panel system has dropped immensely over the past several years, but it’s still a large investment for most homeowners.The cost and possible savings vary depending on some important factors such as:

  • The model of solar panel system you can purchase: This depends on what your budget is.
  • Electricity consumption: The average home in Fairfield doesn’t use much energy, and consequently may not see as many savings on their power bills.
  • The amount of sunlight your city gets: Thanks to Fairfield’s high amount of average daily sunlight, you should be able to save a decent amount on your energy bills.
  • 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 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 $26,000 over the first 20 years with your solar system, too.

So are solar panels worth it? Whether you want to decrease your electric bills, carbon emissions or both, solar panels are a great investment for many Fairfield homeowners.

Solar Incentives in Fairfield

Although solar power is typically a $15,000 to $25,000 investment, it can save you a significant amount of money over the lifespan of your solar panels due to smaller energy bills and government incentives.There are quite a few federal, state and local rebates and tax credits that may earn you a decent amount of money back after paying for solar panels. For more information about incentives that apply to you, check out our article on solar incentives.

Environmental Impact of Switching to Solar in Fairfield

Installing solar panels can have a positive impact on the environment.You may be asking yourself – how much do solar panels do for the planet anyway? One thing to consider is your overall carbon footprint. For example, if you spend lots of time commuting to work and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions.Because solar panels don’t release carbon dioxide emissions into the atmosphere when producing electricity, they’re a good alternative to nonrenewable energy sources. In fact, you could lower your carbon dioxide emissions by about 40 pounds each year. As you can see, going solar has so many other perks beyond saving money. One of the most important ones is that you can help save the planet too.
