Methodology: How We Ranked the Best Solar Companies in Killingly
EcoWatch's solar experts analyzed each solar company in Killingly 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 Killingly
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 Killingly
While solar panels can save you a good amount of money on electricity bills over time, it's important to know the upfront costs. Some important things that determine the cost and possible savings include:
- average energy usage: The more power your household consumes on average and the steeper your current power bills are, the more money you could save by going solar.
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Excluding incentives, you can save an average of $22,000 over the first 20 years with your solar panels, too.
- Your current electricity bills: Solar panels can significantly lower, or totally eradicate, your utility bills. In Killingly, you can save an average of $90 a month.
- Choice of solar panels: The kind of solar panels you choose 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 space isn't a constraint for your project, you can go with a higher number of more affordable panels.
Although a solar panel system costs a sizable chunk of money upfront, it can save you a considerable amount over time. The question of how much, though, depends on a number of factors, like the amount of daily direct sunlight available and your local electricity rates.

Environmental Impact of Switching to Solar in Killingly
If you want to add solar panels to your home, one of the main reasons why may be to lower your carbon footprint. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Killingly, though. In a place like Killingly where commute times can be pretty long, installing solar panels can help offset some of your carbon dioxide emissions from driving a lot. Since solar panels don't release greenhouse gas emissions into the atmosphere when producing electricity, they're a good alternative to nonrenewable energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 40 pounds each year. If you want to do your part for the environment, you'll no doubt recognize that there are many advantages to adopting solar power other than just saving money on electricity. You can also help preserve the environment, which some would argue is priceless.
