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 homeowners, whether or not to invest in solar energy depends the most on the cost. Some important factors that determine how much it will cost to install a solar panel system on your home and how much it could save you over time include:
- Incentives: Tax-paying citizens who purchase and install a solar system this year can save 30% of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $13,000 on your energy bills over 20 years without incentives.
- Your power bills: This will influence how much you can save. In Denville, the average homeowner can save about $670 a year on their electricity bills.
- Your city: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
- The kind of solar panels you can buy: This depends on how much you're willing to invest upfront.
So is a solar system worth it? Whether you'd like to lower your electric bills, carbon dioxide emissions or both, solar panels are a worthwhile investment for many Denville homeowners.

Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Denville, though. The average person has a sizable carbon footprint. Between their car, which is responsible for over 10,000 pounds of carbon dioxide emissions each year, and powering their home, it can be overwhelming to figure out what to do.

As you can see, trading traditional energy for solar has so many other benefits outside of saving money. One of the primary ones is that you can help save the Earth too.

EcoWatch's Denville, NJ Solar Company Rankings FAQs
What is the most reputable solar panel installer in Denville?
The highest-rated local solar company in Denville is Phoenix Energy, with a rating of 5.00 stars.
What are the advantages and disadvantages of solar power?
A few of the biggest pros are that it reduces your power bills, it's good for the environment, and it gives you a decent 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 aren't always aesthetically pleasing.
How long does it take for solar to pay for itself?
Solar panels generally pay for themselves in about 13.9 years, but your solar payback period will vary depending on your utility costs. The more your typical power bill, the quicker your solar panel system will pay for itself.
How long do solar panels last?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is their energy production will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can keep using them at a lower efficiency after that time.
