Methodology: How We Ranked the Best Solar Companies in Sudbury
EcoWatch's solar experts analyzed each solar company in Sudbury 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 Sudbury
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 Sudbury
For the majority of homeowners, whether or not you should invest in a solar energy system boils down to the cost.The overall price and potential savings vary depending on some key factors such as:
- System size and type: Some models are more expensive than others, so the one you choose can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.
- Your current electric bills: Solar panels can greatly reduce, or entirely eliminate, your utility bills. In Sudbury, you can save an average of $1,662 a month.
- How much power your home consumes: Homes that need lots of power each month may require more solar panels and, as a result, more upfront cost, but will also benefit more over time.
- Incentives: Those who buy and install a solar energy system this year can save 0 of their solar installation costs by taking advantage of the federal solar investment tax credit. You can also save about $21,000 on your energy bills over 20 years not including incentives.

Environmental Impact of Switching to Solar in Sudbury
There are many reasons to switch to solar energy, like saving some money on utility bills and helping to reduce your carbon footprint.Something many might be wondering about is how much can they really help preserve the environment by going solar anyway? The EPA reports that electricity generation is the second biggest source of greenhouse gas emissions and about 62% of our electricity comes from burning fossil fuels. Using solar power can help lower that number in a city like Sudbury that generates a fair amount of carbon dioxide emissions each year.In Sudbury, the average household can reduce their carbon footprint by 40 pounds a year after going solar. If you care about the environment, you’ll no doubt recognize that there are many advantages to 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 Sudbury, MA Solar Company Rankings FAQs
Which solar installation company is the best in Sudbury?

Are solar panels actually bad for the environment?
Making solar panels uses chemicals and produces toxic waste that can be harmful for the environment, which is the main drawback of solar panels.
How long does it take to see a return on your investment after getting solar panels?
The average payback period for solar panel installation is about 12.7 years, but the exact period varies depending on local electricity costs, incentives and net metering programs.
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 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, 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 energy generation you want.
