Methodology: How We Ranked the Best Solar Companies in Mastic Beach

EcoWatch's solar experts analyzed each solar company in Mastic Beach 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 Mastic Beach


Below are some the criteria we examined specifically for New York 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 Mastic Beach

The cost of putting up a solar panel system has gone down significantly in the past several years, but it’s still a substantial investment for most homeowners.Some main factors that determine the cost of installing a solar panel system on your home and how much it could save you over time are:

  • Choice of solar panels: The kind of solar panels you want will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If you don’t need to maximize efficiency, you can opt for a higher number of more affordable panels.
  • Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 0 of the project cost. Your state and even local utility companies may also have various incentives that you can use. Additionally, you can save about $22,000 over 20 years on your utility bills, without incentives.
  • The amount of sunlight your city gets: Due to Mastic Beach’s high amount of average daily sunlight, you should be able to save a decent amount on your electric bills.
  • The cost of electricity in your area: If your local power rates are high, there's a better chance you'll have a higher return on your investment in a solar system. In Mastic Beach, you can save an average of $1,525 a month on your electricity bills.

Solar is a rewarding investment for most homeowners. You can make your own energy instead of paying for it from a utility company and make use of solar incentives, all while helping the environment.

Environmental Impact of Switching to Solar in Mastic Beach

There are tons of reasons to make the switch to solar energy, like saving on electricity bills and helping to reduce your carbon footprint.Something many might be asking themselves is how much can they really help protect the environment by going solar anyway? In a city like Mastic Beach where commute times can be very long, installing solar panels can help offset some of your carbon dioxide emissions from driving a lot.Since solar panels don’t release carbon dioxide emissions into the atmosphere when generating electricity, they’re a good swap for traditional energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 100 pounds each year. As you can see, investing in solar has so many other rewards beyond saving money. One of the primary ones is that you can help save the planet too.

Which solar power company is the best in Mastic Beach?

The top local solar company in Mastic Beach is SunPower Corporation, with a rating of 4.00 stars.

What are some of the major advantages and disadvantages of switching to solar?

The advantages of solar power are that it can lower or, in some cases, entirely cut your electricity bills, improve the value of your home and cut back on your carbon footprint. The main disadvantages are that solar panels can be costly to install, you may not see as many savings if you don’t use a lot of electricity and whether you can install solar panels depends on your roof configuration.

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

The average payback period for solar panel installation is about 11.1 years, but the exact period is influenced by the cost of electricity where you are, incentives and net metering programs.

When should I put up solar panels?

Despite summer being the most popular time people install solar panels, the ideal time is actually winter. You can save money since there's not as much demand during the winter months, and it allows you to be up and running with solar for the higher power bills you may get during the summer.

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