Methodology: How We Ranked the Best Solar Companies in Clayton

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


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.

The Cost and Benefits of Solar in Clayton

We understand that for many homeowners, the choice to invest in solar depends on installation costs.The cost and possible savings vary depending on some important factors such as:

  • The model of solar panels you want: More high-tech panels cost more, so that will influence your budget for your solar project.
  • Your city: This affects how much sunlight your roof receives, which helps determine how many panels you need.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, allows you to deduct 0 of the cost of your solar system installation from your federal taxes. In addition, not including incentives, you can save about $33,000 over 20 years on your energy bills.
  • Your home's power bills: Due to fairly high monthly electric bills in Clayton, you could save about $1,500 a year with solar.

Solar is a profitable investment for most homeowners. You can produce your own energy instead of paying for it from a utility company and make use of solar incentives, all while helping the Earth.
