Methodology: How We Ranked the Best Solar Companies in Antioch

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


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 highest-rated local solar company in Antioch is SunPower, with a rating of 4.50 stars.

What are the pros and cons of solar power?

The greatest advantages of solar power are that it can decrease or, for some, 100% cut your electricity bills, raise your home’s value and cut back on your carbon footprint. The disadvantages are that solar panels can be costly to install, you may not save a lot if you don’t use a lot of electricity and whether you can install solar panels depends on your roof configuration.

How long does it take to see a return on your investment after installing solar panels?

Solar panels usually pay for themselves in about 7.0 years, but your solar payback period will depend on your utility costs. The more your typical energy bill, the quicker your solar panel system will recoup your installation costs.

When should I put up solar panels?

Despite summer being the most common time people install solar panels, the perfect time is actually winter. You can save money since there's decreased demand during the winter months, and it lets you be up and running with solar for the more expensive power bills you may get during the summer.
