Methodology: How We Ranked the Best Solar Companies in Cos Cob
EcoWatch's solar experts analyzed each solar company in Cos Cob 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 Cos Cob
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 Cos Cob
When choosing a solar company, most homeowners or business owners think about the costs above all. 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 include:
- The amount of sunlight your roof gets: If your roof doesn't see much direct sunlight, your solar panels won't be able to generate as much energy, which will give you lower savings on energy bills than someone with a roof that gets plenty of sunlight.
- Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, allows you to deduct 30% of the cost of installing your solar panel system from your taxes. Plus, not including incentives, you can save about $23,000 over 20 years on your energy bills.
- Choice of solar panels: The type 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.
- Energy consumption: Solar may be too pricey an option for households that don't use a good amount of energy per month.
Thanks to the cost of solar panels being lower than before as well as various solar incentives, they are a worthwhile investment for the majority of homeowners.

You can learn about the incentives you can take advantage of in our article on solar incentives
Environmental Impact of Switching to Solar in Cos Cob
Installing solar panels is a powerful way to do your part for a greener future. But you may be curious — how much exactly can you help the planet by making the switch to solar? Something that can severely influence your carbon footprint is how long your commute is and how much you drive overall. If you go solar and have an electric car, you can vastly reduce your carbon dioxide emissions by charging your car at home. While making solar panels releases carbon dioxide emissions, the panels make up for it by greatly lowering the amount of CO2 you would have released if you still used nonrenewable energy. In Cos Cob, you can reduce your carbon footprint by 40 pounds a year with solar panels. The benefits of solar power are infinite — just like solar power is! That's why so many homeowners have been happy with making the switch to solar.

EcoWatch's Cos Cob, CT Solar Company Rankings FAQs
What is the most reputable solar panel installer in Cos Cob?
In Cos Cob, Solarmentor.com is the top local solar company. Our team of experts rates it 4.13 stars, so it's a solid choice if you're planning to add solar panels to your house.
Are solar panels actually bad for the environment?
Producing solar panels uses chemicals and produces toxic waste that can be dangerous for the environment, which is the main negative thing about solar panels.
Is it worth putting solar panels on my home?
Solar panels can be a beneficial investment for many homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your energy bills are already fairly low, solar panels might not be for you.
What is the best kind of solar panel?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels are less expensive but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can't, like 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 energy generation you want.
Our goal is to reach as many people as we can with sensible solutions like solar energy.
