Methodology: How We Ranked the Best Solar Companies in Northfield
EcoWatch's solar experts analyzed each solar company in Northfield 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 Northfield
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 Northfield
Even though solar panels can save you money on energy over time, it's necessary to take into consideration the startup costs. Some significant things that affect the upfront cost and potential savings over time include:
- Choice of solar panels: The type of solar panels you get will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.
- Your energy consumption: If your home needs to use a lot of energy, you'll reap more rewards from going solar.
- The cost of energy for you: If your local electricity rates are quite high, there's a good chance you'll get a higher return on your investment in a solar system. In Northfield, you can save an average of $82 a month on your electricity bills.
- Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 30% of the project cost. Your state and even local utility companies may also have various incentives that you can benefit from. Plus, you can save about $21,000 over 20 years on your utility bills, before factoring in incentives.
Solar is a worthwhile investment for most homeowners. You can generate your own power instead of paying for it from the grid and make use of solar incentives and rebates, all while helping the planet.

What is the best solar panel installer in Northfield?
In Northfield, Valley Solar is the top local solar company. Our team of experts rates it 4.06 stars, so it's a good choice if you're looking to add solar panels to your house.
Are solar panels actually environmentally friendly?
Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to recycle safely once they've reached the end of their lifespan. Making solar panels uses a lot of energy as well. The energy payback period is about 1 to 4 years.
How long does it take for solar to pay for itself?
The average payback period for solar panel installation is about 9.5 years, but the exact period varies depending on local electricity costs, incentives and net metering programs.
When is the best time of year to install solar panels?
Although summer is the most common time people install solar panels, the perfect time is actually winter. You can save money since there's less demand during the winter months, and it lets you be up and running with solar for the higher power bills you may get during the summer.
