Methodology: How We Ranked the Best Solar Companies in Watertown
EcoWatch's solar experts analyzed each solar company in Watertown 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 Watertown
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 Watertown
For many people, the decision of which solar company to go with depends on prices. The cost and possible savings vary depending on some important factors such as:
- The amount of sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar system won't be able to make as much energy, which will give you lower savings on power bills than a house with a roof that gets plenty of sunlight.
- 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 lets you deduct from your taxes a percentage of the project cost. You can also save on your energy bills, which can generate an average of $22,000 of savings over 20 years.
- average energy usage: The more energy your home uses on average and the larger your current energy bills are, the more benefits you'll see from going solar.
- System size and type: Some models are more costly than others, so the one you get can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
Due to the cost of solar panels being lower than before as well as local and federal solar incentives, they are a cost-effective investment for many homeowners.

Environmental Impact of Switching to Solar in Watertown

In a city like Watertown where energy use is somewhat high, making the switch to solar power is a good plan for people who are eco-conscious. When you go solar, your carbon dioxide emissions can be lowered by about 40 pounds each year. For homeowners who want to help the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.
