Methodology: How We Ranked the Best Solar Companies in Green Knoll

EcoWatch's solar experts analyzed each solar company in Green Knoll 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 Green Knoll


Below are some the criteria we examined specifically for New Jersey 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 Green Knoll

When deciding on a solar company, most homeowners or business owners think about the costs above all.The cost and possible savings vary depending on some key factors such as:

  • How much energy you use: If your home needs to use a lot of energy, you'll see more savings from switching to solar.
  • Incentives: Something that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save money on your power bills, which can give you an average of $14,000 of savings over 20 years.
  • Choice of solar panels: The type of solar panels you buy 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 go with a higher number of more affordable panels.
  • The amount of sunlight your city gets: Due to Green Knoll’s high amount of average daily sunlight, you should be able to save a decent amount on your electricity bills.

Even though a solar panel system costs a good 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, like the amount of daily direct sunlight available and your local electricity rates.
