Methodology: How We Ranked the Best Solar Companies in Killingworth

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


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 Killingworth

For most homeowners, the decision to invest in solar energy comes down to the cost.The installation cost is just one important factor you should keep in mind when looking into installing solar panels. How much it'll cost and how much you can save depend on things including:

  • The kind of solar panels you want to get: Some are more costly, so that will shape your budget for your solar project.
  • Average daily sunlight: Since Killingworth 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 electricity bills will be.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 0 of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Aside from incentives, you can save an average of $23,000 over the first 20 years with your system, too.
  • How much power your household needs: If your home regularly uses a lot of energy, you'll reap more rewards from installing solar panels.

So is installing solar panels worth it? Whether you want to lower your energy bills, greenhouse gas emissions or both, solar panels are a great investment for many Killingworth homeowners.

Solar Incentives in Killingworth

If you’re planning on switching to solar energy, various government incentives and solar rebates can dramatically bring down the installation costs and speed up the return on your investment.On top of the federal solar investment tax credit, there are also some state- and city-level programs, which in almost all cases, can be claimed in addition to the federal incentive, so you can save even more.

Environmental Impact of Switching to Solar in Killingworth

One reason so many homeowners are considering going solar is to help lower their environmental impact.But how much can switching to solar actually affect the environment? Something that can dramatically influence your carbon footprint is how long your commute is and how much you drive in general. If you go solar and have an electric car, you can greatly cut back on your carbon dioxide emissions by charging your car at home.In fact, if you adopt solar power, you could reduce your carbon dioxide emissions by about 40 pounds each year. If you care about the environment, you’ll no doubt understand that there are many benefits of adopting solar energy other than just saving money on electricity. You can also help protect the environment, which some would argue is invaluable.

EcoWatch's Killingworth, CT Solar Company Rankings FAQs

Which solar installation company is the best in Killingworth?

The best local solar company in Killingworth is SunRun Solar, with a rating of 3.00 stars.

Are solar panels actually eco-friendly?

Manufacturing solar panels needs to use chemicals and produces toxic waste that can be harmful for the environment, which is the main drawback of solar panels.

Are solar panels worth it?

Solar panels can be a great investment for most homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your power bills are already fairly low, solar panels might not be for you.

What are the different types of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and how much efficiency you're looking for.
