Methodology: How We Ranked the Best Solar Companies in Lomita

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


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.

High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If you don’t need to maximize efficiency, you can go with a higher number of more affordable panels.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, allows you to deduct 0 of the cost of installing your solar panel system from your federal taxes. Additionally, not including incentives, you can save about $28,000 over 20 years on your energy bills.
  • Your home's orientation toward the sun: This, plus how your roof is set up, affects affect how much electricity your solar panels can make.
  • Electricity consumption: The average household in Lomita doesn’t use much energy, and so may not see as many savings on their power bills.

The energy payback period is about 1 to 4 years.

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

Solar panels generally pay for themselves in about 8.4 years, but your solar payback period will vary depending on your utility costs. The higher your typical power bill, the quicker your solar panel system will recoup your installation costs.

What is the efficiency of solar panels?

For the most part, solar panels are about 15 to 25% efficient, which means they can convert that percentage of the sun’s energy into usable electricity.
