Methodology: How We Ranked the Best Solar Companies in Cerritos

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


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 Cerritos

When deciding on a solar company, most homeowners or business owners care about the costs the most.The installation cost is just one important factor you should keep in mind when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • Incentives: Tax-paying citizens who buy and install a solar energy system this year can save 0 of their installation costs by taking advantage of the federal solar investment tax credit. You can also save about $25,000 on your electricity bills over 20 years not including incentives.
  • Choice of solar panels: The type of solar panels you are interested in getting will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.
  • Energy consumption: Solar may be a high-cost option for homes that don’t need a lot of energy per month.
  • How much energy costs for you: The typical family in Cerritos pays around $1,200 a year on power alone, so you could gain that much in savings.

There are lots of good benefits of solar despite the upfront cost of installation. It can help the Earth and your wallet. Additionally, it can boost the value of your home, giving you even more benefits if you want to sell your home later.

EcoWatch's Cerritos, CA Solar Company Rankings FAQs

Which solar company is the best in Cerritos?

In Cerritos, SunPower by Sea Bright Solar is the best local solar company. Our team of experts rates it 4.40 stars, so it's a good choice if you're planning on installing solar panels on your house.

What are a few of the advantages and disadvantages of going solar?

The main advantages of solar power are that it can decrease or, for some, completely eradicate your electricity bills, raise the value of your home and cut back on your carbon footprint. The disadvantages are that solar panels can be costly to install, you may not see as many savings 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 for solar to pay for itself?

Solar panels usually pay for themselves in about 9.2 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.

How long do solar panels last?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. 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 continue to use them at a lower efficiency after that time.
