Methodology: How We Ranked the Best Solar Companies in Chelmsford
EcoWatch's solar experts analyzed each solar company in Chelmsford 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 Chelmsford
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 Chelmsford
While solar panels can save you money on power bills over time, it's necessary to take into consideration the upfront costs. The cost and possible savings vary depending on some important factors such as:
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 30% of your total installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Excluding incentives, you can save an average of $22,000 over 20 years with your solar system, too.
- Your income and budget: This guides what kind of solar panels you can buy.
- Typical energy usage: The more energy your household consumes on average and the higher your current energy bills are, the more likely you'll benefit from switching to solar.
- Your energy bills: This will dictate your savings. In Chelmsford, the average homeowner can save about $1,000 a year on their electricity bills.
So is installing solar panels worth it? Whether you'd like to lower your electricity costs, greenhouse gas emissions or both, solar panels are a worthwhile investment for many Chelmsford homeowners.

Solar Incentives in Chelmsford
In an effort to increase the adoption of solar power, incentives are offered by the government — and even some utility companies — to help make switching to solar power more economically viable and accessible. These incentives normally consist of cash rebates, tax breaks and/or solar renewable energy credits. They can reduce how much you pay for installing solar panels by 30%, upwards of 50% in some cases. 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 Chelmsford
One of the reasons so many people are thinking of installing solar panels is to help bring down their environmental impact. But you may be curious — how much exactly can you help by going solar? An important thing to think about is your overall carbon footprint. For example, if you have a long commute, your footprint may be greater, so adopting solar energy for your house can help offset that. Even though making solar panels emits carbon dioxide, the panels make up for it by greatly reducing the amount of CO2 you would have produced if you still used nonrenewable energy. In Chelmsford, you can reduce your carbon footprint by 40 pounds a year with solar panels. Since solar power is renewable and makes electricity without CO2 emissions, making the switch to solar power is one easy step you can take to help the planet.
