Methodology: How We Ranked the Best Solar Companies in Danbury

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


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 Danbury

The cost of putting up a solar panel system has gone down immensely in the past several years, but it’s still a large investment for most homeowners.A few main factors that determine how much it will cost to install a solar panel system on your home and how much it could save you over time are:

  • Incentives: Tax-paying citizens who install a solar system this year can save 0 of their solar installation costs by taking advantage of the federal solar investment tax credit. You can also save about $24,000 on your electricity bills over 20 years not including incentives.
  • The amount of sunlight your roof gets: If your roof gets limited direct sunlight, your solar system won’t be able to produce as much energy, which will leave you with lower savings on electricity bills than a house with a roof that gets lots of sunlight.
  • Choice of solar panels: The type of solar panels you need 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 you don’t need to maximize efficiency, you can go with a higher number of more affordable panels.
  • Electricity consumption: The average home in Danbury doesn’t use much energy, and so may not see as many savings on their power bills.

Solar is a worthwhile investment for most homeowners. You can generate your own energy instead of paying for it from a utility company and benefit from solar incentives and rebates, all while helping preserve the Earth.

Solar Incentives in Danbury

Although a solar power system is typically a $15,000 to $25,000 investment, it can save you a substantial amount of money over several years due to lower power bills and government incentives.You are eligible for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar system. You can also potentially use the ITC with other local rebates and benefits. Our article on solar incentives goes over more in-depth information on the incentives you can find in Danbury.

Environmental Impact of Switching to Solar in Danbury

One of the reasons so many people are considering adopting solar energy is to help reduce their environmental impact.You may be asking yourself – how much does making the switch help the environment anyway? The average person has a sizable carbon footprint. Between their car, which produces over 10,000 pounds of carbon dioxide emissions each year, and electricity for their home, it can be overwhelming to think about what to do. Installing solar panels is one of the easiest things you can do to help.Because solar panels don’t release greenhouse gas emissions into the atmosphere when creating electricity, they’re a good trade for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 40 pounds each year. For people who care about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.
