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

For many people considering switching to solar, the decision of which solar company to go with depends on prices. A few main factors that affect the cost of installing a solar panel system on your home and how much it could save you over time include:

  • 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 on your power bills, which can generate an average of $24,000 of savings over 20 years.
  • How much power your home consumes: Homes that consume lots of power each month may call for more solar panels and, as a result, be more expensive, but will also benefit more over time.
  • Your income and budget: This shapes what kind of solar panels you can buy.
  • How much energy costs for you: The average family in Danbury shells out around $1,100 a year on energy use alone, so you could end up with that much in savings.

Though a solar panel system costs a sizable chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on a number of factors, like the angle of your roof and your local electricity rates.

When you install solar panels on your home, you can take advatage of the federal tax credit, or ITC. This credit currently reduces your tax bill by 30% of the cost of your solar panels. Additionally, there may often be some local incentives that you can benefit from to further cut back on the cost of solar of solar panels.

Environmental Impact of Switching to Solar in Danbury

Swapping traditional energy for solar is a good way to do what you can for a more environmentally-friendly future. You may be trying to figure out — how much does making the switch 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 use solar energy for your home to power your EV and therefore help offset your carbon emissions. In fact, if you install solar panels, you could expect to reduce your carbon dioxide emissions by about 40 pounds each year. Since solar energy is abundant and makes electricity without CO2 emissions, adding solar panels to your home is one easy step you can take to help the environment.
