Methodology: How We Ranked the Best Solar Companies in Williamstown
EcoWatch's solar experts analyzed each solar company in Williamstown 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 Williamstown
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 Williamstown
Even though solar panels can help save you a decent chunk of change on power bills over time, it's important to take into consideration the upfront costs. A few important factors that determine the cost of installing solar panels on your home and how much money you could save over time are:
- Your current energy bills: Solar panels can noticeably decrease, or entirely get rid of, your utility bills. In Williamstown, you can save an average of $83 a month.
- Where your home is: This affects how much sunlight your roof receives, which helps determine how many panels you need.
- The type of solar panels you want to get: More efficient models are more costly, so that will affect your budget for your solar project.
- Incentives: Those who purchase and install a solar energy system this year can save 30% of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $21,000 on your electricity bills over 20 years not including incentives.
Although a solar panel system costs a decent chunk of money upfront, it can save you much more in the long term. The question of how much, though, depends on a number of factors, including the size of your house and incentives.

Environmental Impact of Switching to Solar in Williamstown
Many want to do their part to help save the planet, which often is the chief motivation to install solar panels. You may be asking yourself — how much does making the switch do for the environment anyway? If your family uses a lot of energy, you can have an even greater impact on the planet by switching to solar energy. When you go solar, your carbon dioxide emissions can be reduced by about 40 pounds each year. For homeowners who care about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.

What are a few of the biggest pros and cons of adopting solar power?
The advantages of solar power are that it can reduce or, in some cases, 100% eradicate your electricity bills, raise the value of your home and bring down your carbon footprint. The disadvantages are that solar panels can be expensive to install, you may not save a lot if you don't use a lot of electricity and it doesn't work for all roof types and locations.
How long does it take for solar to pay for itself?
Solar panels typically pay for themselves in about 9.3 years, but your solar payback period will vary based on your utility costs. The higher your typical power bill, the faster your solar panel system will recoup your installation costs.
When should I install solar panels?
You can install solar panels whenever it's convenient for you, but consider doing so in the winter when there's less demand. With fewer homeowners going solar, you could potentially see quicker installation times and more savings.
