Methodology: How We Ranked the Best Solar Companies in Westminster
EcoWatch's solar experts analyzed each solar company in Westminster 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 Westminster
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 Westminster
Although solar panels can help save you a decent chunk of change on power bills over time, it's necessary to consider the upfront costs. The installation cost is just one important factor you should bear in mind when looking into installing solar panels. How much it'll cost and how much you can save depend on things such as:
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Not including incentives, you can save an average of $23,000 over the first 20 years with your solar system, too.
- Your income and budget: This shapes what model of solar panels you can purchase.
- average energy usage: The more power your household uses on average and the higher your current power bills are, the more money you could save by making the switch to solar.
- How much you spend on energy: The typical family in Westminster shells out around $1,100 a year on energy use alone, so you could be looking at that much in savings.
Thanks to solar panels now being cheaper than ever as well as several solar incentives, they are a solid investment for the majority of homeowners.

Environmental Impact of Switching to Solar in Westminster
Swapping traditional energy for solar is a great way to do your part for a more sustainable future. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Westminster, though. Something that can dramatically shape your carbon footprint is your commute time and how much you drive altogether. If you install solar panels and drive an electric car, you can vastly decrease your carbon dioxide emissions by charging your car at home. In Westminster, the average household can lower their carbon footprint by 40 pounds a year once they go solar. For homeowners who care about the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.

EcoWatch's Westminster, MA Solar Company Rankings FAQs
Which solar power company is the best in Westminster?
In Westminster, United Better Homes is the most reputable local solar company. Our team of experts rates it 5.00 stars, so it's a solid choice if you're looking to install solar panels on your roof.
What are some of the biggest pros and cons of installing solar panels?
A few of the biggest pros are that it lowers your power bills, it's good for the environment, and it provides a good return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, the installation cost is pricey and solar panels aren't always aesthetically pleasing.
Is it worth putting solar panels on my home?
Solar panels require a large upfront investment that costs over ten thousand dollars, but whether or not solar panels are worth it depends on a range of factors like local electricity rates and how much direct sunlight your roof gets.
How long do solar panels last?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of. What this means is how much energy they produce will have decreased by about 0.8% each year since installing them. You can opt to replace them once you've had them for that long or you can keep using them at a lower efficiency after that time.
