Methodology: How We Ranked the Best Solar Companies in Derby

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


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 Derby

Solar panels are powered by a free energy source — the sun — but before you can take advantage of this you will need to pay to set up your system. The overall price and potential savings vary depending on a few important factors such as:

  • Incentives: The federal solar investment tax credit, which can save you some money, lets you deduct 30% of the cost of your solar system installation from your federal taxes. Plus, not including incentives, you can save about $25,000 over 20 years on your energy bills.
  • The kind of solar panel system you can afford: This hinges on how much you're willing to spend upfront.
  • Average daily sunlight: Since Derby gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which impacts how much your solar panels can save you on your electricity bills.
  • Typical energy usage: The more electricity your household uses on average and the greater your current electricity bills are, the more money you could save by going solar.

Even though a solar panel system costs a decent chunk of money upfront, it can save you much more in the long term. The question of how much, though, depends on several factors, like the size of your solar panel system and incentives.

Solar Incentives in Derby

Adopting solar power has a lot of considerable benefits. Not only can it help protect the planet, but you can also save a good amount of money on your installation with various government incentives. These incentives typically consist of cash rebates, tax breaks and/or solar renewable energy credits. They can reduce how much you end up spending on installing solar panels by 30%, upwards of 50% in some cases. Our article on solar incentives has more in-depth information on the incentives you can take advantage of in Derby.

Environmental Impact of Switching to Solar in Derby

There are lots of reasons to trade traditional energy for solar power, like saving on electricity bills and helping to reduce your carbon footprint. But you may be curious — how much exactly can you help the planet by using solar power? A significant thing to keep in mind is your overall carbon footprint. For example, if you spend a lot of time driving to work, your footprint may be larger, so switching to solar power for your house can help offset that. When you go solar, your carbon footprint can be cut by about 40 pounds each year. As you can see, trading traditional energy for solar has so many other rewards beyond saving money. One of the primary ones is that you can help save the environment too.
