Methodology: How We Ranked the Best Solar Companies in Groton
EcoWatch's solar experts analyzed each solar company in Groton 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 Groton
Below are some the criteria we examined specifically for Massachusetts 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 Groton
Although solar panels can help save you a good amount of money on utility bills over time, it's important to consider the upfront costs. Some important things that determine the upfront cost and potential savings over time include:
- The cost of electricity in your area: If your local utility rates are quite high, there's a good chance you'll have a higher return on your investment in a solar system. In Groton, you can save an average of $86 a month on your electricity bills.
- Your home's orientation toward the sun: This, and the configuration of your roof, affects affect how much power your solar panels can make.
- Incentives: Those who buy and install a solar energy system this year can save 30% of their overall solar costs by taking advantage of the federal solar investment tax credit. You can also save about $22,000 on your energy bills over 20 years without incentives.
- The type of solar panel system you can afford: This is dependent on how much you're willing to spend upfront.
There are many great benefits of solar in spite of the upfront cost of installation. It can help the Earth and your wallet. Additionally, it can raise the value of your home, giving you even more benefits if you decide to sell your home later.

Environmental Impact of Switching to Solar in Groton
Installing solar panels is a compelling way to do your part for a greener future. But how much can installing solar panels actually help the environment? One thing to keep in mind is your overall carbon footprint. For example, if you spend lots of time commuting to work and have an electric vehicle, you can install solar panels on your home to power your EV and therefore help offset your carbon emissions. While solar panel production releases carbon dioxide emissions, the panels make up for it by significantly lowering the amount of CO2 you would have released if you still used nonrenewable energy. In Groton, you can reduce your carbon footprint by 40 pounds a year with solar panels. As you can see, going solar has so many other benefits apart from saving money. One of the primary ones is that you can help save the environment too.

Are solar panels really eco-friendly?
Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the construction.

The energy payback period is about 1 to 4 years.
How long does it take for solar to pay for itself?
Solar panels generally pay for themselves in about 8.9 years, but your solar payback period will depend on your utility costs. The higher your typical energy bill, the quicker your solar panel system will recoup your installation costs.
How much solar panel capacity do I need for my house?
Solar panel capacity is how much energy the panels can generate under ideal conditions (a sunny day around noon). The average household has to install between 20 and 35 panels to account for their energy needs.
