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 Illinois 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.

What is the top solar installer in Princeton?

In Princeton, Sunrun Solar is the top local solar company. Our team of experts rates it 4.80 stars, so it's a good choice if you're looking to install solar panels on your roof.

Are solar panels actually good for the environment?

Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Solar panel manufacturing uses a lot of energy as well. The energy payback period is about 1 to 4 years.

How long does it take for solar to pay for itself?

Solar panels typically pay for themselves in about 17.5 years, but your solar payback period will vary based on your utility costs. The higher your typical electricity bill, the quicker your solar panel system will pay for itself.

When should I put up solar panels?

Although summer is the most common time people install solar panels, the best time is actually winter. You can save money since there's less demand during the winter months, and it lets you be up and running with solar for the higher power bills you may get during the summer.
