Methodology: How We Ranked the Best Solar Companies in Denville

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


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 Denville

For many people, the decision of which solar installer to hire depends on total costs.The installation cost is just one important factor you should take into account when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • The type of solar panels you want to get: More efficient models cost more, so that will determine your budget for your solar project.
  • How much energy costs for you: If your local electricity rates are high, there's a better chance you'll get a higher return on your investment in solar panels. In Denville, you can save an average of $1,059 a month on your electricity bills.
  • How much sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panel system won’t be able to make as much energy, which will give you lower savings on power bills than someone with a roof that gets plenty of sunlight.
  • Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 0 of the project cost. Your state and city may also have various incentives that you can take advantage of. In addition, you can save about $13,000 over 20 years on your utility bills, not including incentives.

Although a solar panel system costs a sizable chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on a number of factors, such as the angle of your roof and your current power bills.

Solar Incentives in Denville

Adopting solar power has a lot of wonderful benefits. Not only can it help protect the environment, but you can also save a good amount of money on your installation with various government incentives.Local solar incentives depend on the location and, sometimes, utility company.

In our article on solar incentives, you can read about the incentives you qualify for near you.

Environmental Impact of Switching to Solar in Denville

There are a few main reasons why many people want to invest in solar energy: for the good of their bank accounts and the planet.A question many people might be asking themselves is how much can they really help preserve the environment by switching to solar power anyway? The EPA reports that electricity production is the second greatest source of greenhouse gas emissions and about 62% of our electricity is produced by burning fossil fuels. Switching to a clean energy source like solar power can help reduce that statistic in a city like Denville that generates a fair amount of carbon dioxide emissions each year.In fact, if you adopt solar power, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. Since solar power is abundant and generates electricity without releasing carbon emissions, making the switch to solar power is one easy step you can take to help protect the environment.
