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

Solar panels run off a free energy source — the sun — but before you can take advantage of this you must first pay to set up your system.Some important things that influence the upfront cost and potential savings over time include:

  • Choice of solar panels: The type of solar panels you get will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If you don’t need to maximize efficiency, you can go with a higher number of more affordable panels.
  • Your household's power bills: Due to fairly high monthly electric bills in Sudbury, you could save about $1,700 a year with solar.
  • Typical energy usage: The more electricity your household consumes on average and the steeper your current energy bills are, the more benefits you’ll see from making the switch to solar.
  • Incentives: Something that can make your solar project cost less 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 money on your utility bills, which can lead to an average of $21,000 of savings over 20 years.

There are lots of great benefits of solar despite the initial cost of installation. It can help the planet and your wallet. Plus, it can raise the value of your home, resulting in even more benefits if you want to sell your home later.

Solar Incentives in Sudbury

Because solar power is better for the environment than fossil fuels, there are some government incentives available to encourage its adoption.In addition to the federal solar investment tax credit, there are also some state- and city-level incentives, which in most cases, can be claimed in addition to the federal incentive, so you get to save even more. In our article on solar incentives, you can find out about the incentives you qualify for near you.

Environmental Impact of Switching to Solar in Sudbury

Replacing nonrenewable energy with solar power is a powerful way to do your part for a greener future.Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Sudbury, though. 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 accounts for a fair amount of carbon dioxide emissions each year.In fact, if you adopt solar power, 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 likely 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?

The best local solar company in Sudbury is SunPower by BlueSel Home Solar, with a rating of 3.00 stars.

What is the negative environmental impact of making solar panels?

Manufacturing solar panels requires chemicals and produces toxic waste that can be dangerous for the environment, which is the main negative thing about solar panels.

How long does it take for solar to pay for itself?

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 kinds of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can’t, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof configuration and desired energy output.
