Methodology: How We Ranked the Best Solar Companies in Princeton

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


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 Princeton

For many people, the decision of which solar company to choose depends on prices. Some key factors that dictate how much it will cost to install solar panels on your home and how much money you could save over time include:

  • Incentives: The federal solar investment tax credit currently lets you lower your taxes by 30% of the project cost. Your state may also have various incentives that you can benefit from. Additionally, you can save about $14,000 over 20 years on your utility bills, not including incentives.
  • How much you spend on energy: The average family in Princeton shells out around $710 a year on energy alone, so you could end up with that much in savings.
  • System size and type: Some models are more expensive than others, so the one you get can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
  • How much sunlight your roof gets: This, plus how your roof is set up, affects affect how much power your solar panels can generate.

So is a solar panel system worth it? Whether you want to reduce your electric bills, carbon emissions or both, solar panels are a solid investment for many Princeton homeowners.

Environmental Impact of Switching to Solar in Princeton

Making the switch to solar power is a compelling way to do your part for a more eco-friendly future. You may be trying to figure out — how much do solar panels help the environment anyway? An important thing to be mindful of is your overall carbon footprint. For example, if your commute is very long, your footprint may be greater, so switching to solar energy for your house can help offset that. In Princeton, the average resident can reduce their carbon footprint by 60 pounds a year once they go solar. For people who are worried about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.
