Methodology: How We Ranked the Best Solar Companies in Cambridge
EcoWatch's solar experts analyzed each solar company in Cambridge 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 Cambridge
Below are some the criteria we examined specifically for Vermont 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 Cambridge
For many people, the decision of which solar installer to choose comes down to pricing.The installation cost is just one important factor you should take into account when looking into installing solar panels. How much it'll cost and how much you can save depend on things including:
- The cost of energy for you: If your local utility rates are quite high, there's a good chance you'll see a higher return on your investment in solar panels. In Cambridge, you can save an average of $1,346 a month on your electricity bills.
- Incentives: Tax-paying citizens who buy and install a solar system this year can save 0 of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $24,000 on your electricity bills over 20 years excluding incentives.
- Typical energy usage: The more energy your household consumes on average and the higher your current energy bills are, the more benefits you’ll see from switching to solar.
- The amount of sunlight your roof gets: Due to Cambridge’s relatively low amount of average daily sunlight, you might not see as many savings on your power bills.
Solar is a profitable investment for most homeowners. You can make your own energy instead of paying for it from the grid and benefit from solar incentives, all while helping protect the Earth.

EcoWatch's Cambridge, VT Solar Company Rankings FAQs
What is the most reputable solar panel installation company in Cambridge?
The best local solar company in Cambridge is Green Mountain Solar, with a rating of 4.90 stars.
Are solar panels really environmentally friendly?
Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to recycle safely once they’ve reached the end of their lifespan. Solar panel manufacturing uses a lot of energy as well. The energy payback period is about 1 to 4 years.
Are solar panels worth it?
Solar panels require a large upfront investment that will cost you several thousands of 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.
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 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 layout and how much efficiency you're looking for.
