Methodology: How We Ranked the Best Solar Companies in Harvard

EcoWatch's solar experts analyzed each solar company in Harvard 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 Harvard


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 Harvard

When picking a solar company, most homeowners or business owners wonder about the costs above all.There are quite a few factors you should consider when trying to figure out how much it will cost and how much you can save, such as:

  • Incentives: The federal solar investment tax credit currently lets you decrease your taxes by 0 of the project cost. Your state may also have various incentives that you can benefit from. In addition, you can save about $20,000 over 20 years on your utility bills, not including incentives.
  • Your income and budget: This shapes what kind of solar panels you can afford.
  • The amount of sunlight your roof gets: Due to Harvard’s high amount of average daily sunlight, you should be able to save a decent amount on your electric bills.
  • Your power bills: This will affect how much you can save. In Harvard, the average resident can save about $1,700 a year on their electricity bills.

Even though a solar panel system costs a sizable chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on a number of factors, including the kind of solar panels you get and incentives.

Solar Incentives in Harvard

There are many reasons why going solar is a great investment. One of them consists of some government incentives you can take advantage of.Local solar incentive programs depend on the location and, sometimes, utility company. A lot of states offer rebates for solar panels, in addition to the federal solar tax credit. For detailed information about incentives that apply to you, visit our article on solar incentives.

Environmental Impact of Switching to Solar in Harvard

If you want to add solar panels to your home, one of the major reasons why may be to lower your carbon footprint.A question many might be asking themselves is how much can they really help protect the environment by going solar anyway? Switching to solar power is a great choice for the environment, because the largest source of greenhouse gas emissions in the nation is from burning fossil fuels for electricity, heat, and transportation – all of which can be powered by solar instead.Although making solar panels emits carbon dioxide, the panels make up for it by considerably lowering the amount of CO2 you would have produced if you still used nonrenewable energy. In Harvard, you can reduce your carbon footprint by 40 pounds a year with solar panels. If you want to do your part for the environment, you’ll most likely recognize that there are many benefits of adopting solar power other than just saving money on bills. You can also help preserve the environment, which some would argue is more valuable.

EcoWatch's Harvard, MA Solar Company Rankings FAQs

What is the top solar company in Harvard?

The best local solar company in Harvard is SunPower by BlueSel Home Solar, with a rating of 3.00 stars.

What are a few of the advantages and disadvantages of going solar?

A few of the biggest pros are that it lets you spend less on your electricity bills, it’s good for the environment, and it can give you a decent return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, there is a high upfront cost and solar panels aren’t always aesthetically pleasing.

How long does it take to see a return on your investment after installing solar panels?

Solar panels typically pay for themselves in about 13.3 years, but your solar payback period will depend on your utility costs. The more your typical energy bill, the faster your solar panel system will recoup your installation costs.

How often do solar panels need to be replaced?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
