Methodology: How We Ranked the Best Solar Companies in Kentfield

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


Below are some the criteria we examined specifically for California 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.

EcoWatch's Kentfield, CA Solar Company Rankings FAQs

What is the best solar panel installer in Kentfield?

The top local solar company in Kentfield is SunPower, with a rating of 4.50 stars.

What are the best and worst things about solar power?

The main advantages of solar power are that it can decrease or, in some cases, entirely erase your electricity bills, raise the value of your home and lower your carbon footprint. The disadvantages are that solar panels can be expensive to install, you may not save a lot if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.

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

Solar panels usually pay for themselves in about 7.3 years, but your solar payback period will vary based on your utility costs. The higher your typical power bill, the faster your solar panel system will pay for itself.

How long do solar panels last?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is how much energy they produce will have decreased by about 0.8% each year since installing them. You can choose to replace them once you've had them for that long or you can keep using them at a lower efficiency after that time.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
