Methodology: How We Ranked the Best Solar Companies in Holliston
EcoWatch's solar experts analyzed each solar company in Holliston 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 Holliston
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 Holliston
We get that for many homeowners, the decision to invest in solar rests on installation costs. There are a few factors you should take into consideration when trying to figure out how much it will cost and how much you can save, including:
- How much energy costs for you: The average household in Holliston spends around $1,000 a year on power alone, so you could end up with that much in savings.
- How much electricity your home consumes: Homes that consume plenty of power each month may require more solar panels and, as a result, more upfront cost, but will also save more on their energy bills over time.
- Incentives: Tax-paying citizens who install a solar energy system this year can save 30% of their total solar spend by using the federal solar investment tax credit. You can also save about $22,000 on your electricity bills over 20 years excluding incentives.
- System size and type: Some models are more expensive than others, so the one you want to get can raise or lower your upfront cost. Plus, the more solar panels you need, the more it'll cost.
As a result of solar panels now being cheaper than ever as well as several solar incentives, they are a sound investment for the majority of homeowners.

Our article on solar incentives goes over more in-depth information on the incentives you can benefit from in Holliston.
Environmental Impact of Switching to Solar in Holliston
One reason so many homeowners consider going solar is to help lower their environmental impact. But how much can switching to solar actually affect the environment? In a place like Holliston where commute times can be very long, installing solar panels can help help reduce the carbon footprint of driving a lot. Because solar panels don't release carbon dioxide emissions into the atmosphere when creating electricity, they're a good alternative to traditional energy sources. In fact, you could lower your carbon dioxide emissions by about 40 pounds each year. The advantages of solar power are infinite — just like solar power is! That's why so many homeowners have been happy with committing to solar.

EcoWatch's Holliston, MA Solar Company Rankings FAQs
Which solar company is the best in Holliston?
The top local solar company in Holliston is United Better Homes, with a rating of 5.00 stars.
What are the pros and cons of solar power?
A few of the biggest pros are that it lets you spend less on your electricity bills, it's a sustainable source of energy, and it gives you a decent return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, they cost a lot upfront and solar panels can look clunky on your roof.
How long does it take for solar to pay for itself?
Solar panels typically pay for themselves in about 8.8 years, but your solar payback period will depend on your utility costs. The more your typical electricity bill, the quicker your solar panel system will pay for itself.
When is the best time of year to install solar panels?
You can put up solar panels whenever it's convenient for you, but consider doing it in the winter when there's less demand. With fewer homeowners contracting installers, you could potentially see faster installation times and more savings.
