Methodology: How We Ranked the Best Solar Companies in Eastham

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


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 Eastham

For many homeowners, the decision to invest in solar energy depends the most on the cost.There are several factors you should consider when determining how much it will cost and how much you can save, such as:

  • The amount of sunlight your city gets: Due to Eastham’s high amount of average daily sunlight, you should be able to save a decent amount on your power bills.
  • Incentives: One thing that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that’s equal to a percentage of the project cost. You can also save money on your utility bills, which can result in an average of $24,000 of savings over 20 years.
  • The type of solar panels you have the money for: This depends on what your budget is.
  • How much energy costs for you: The typical household in Eastham pays around $1,600 a year on electricity alone, so you could gain that much in savings.

Though a solar panel system costs a decent chunk of money upfront, it can save you a considerable amount in the long term. The question of how much, though, depends on several factors, like the size of your solar panel system and your energy consumption.

EcoWatch's Eastham, MA Solar Company Rankings FAQs

What is the best solar installation company in Eastham?

The highest-rated local solar company in Eastham is SunPower by BlueSel Home Solar, with a rating of 3.00 stars.

What are the biggest advantages and disadvantages of adopting 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 provides a good 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 be an eyesore.

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

Solar panels typically pay for themselves in about 11.2 years, but your solar payback period will vary based on your utility costs. The higher your typical electricity bill, the faster your solar panel system will pay for itself.

What is the best type of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and how much efficiency you're looking for.
