Methodology: How We Ranked the Best Solar Companies in Los Angeles

EcoWatch's solar experts analyzed each solar company in Los Angeles 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 Los Angeles


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 Los Angeles

For most homeowners, whether or not you should invest in a solar energy system depends the most on the cost.Some main factors that dictate the cost of installing solar panels on your home and how much money you could save over time include:

  • Choice of solar panels: The kind of solar panels you get will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
  • Energy consumption: Installing solar panels may be too pricey an option for homes that don’t use a good amount of energy per month.
  • Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 0 of the project cost. Your state and city may also have incentives and rebates that you can use. In addition, you can save about $30,000 over 20 years on your utility bills, before factoring in incentives.
  • How much sunlight your roof gets: This, along with how your roof is set up, affects affect how much power your solar panels can produce.

Solar is a fruitful investment for most homeowners. You can generate your own power instead of paying for it from a utility company and make use of solar tax credits and rebates, all while helping protect the environment.

EcoWatch's Los Angeles, CA Solar Company Rankings FAQs

What is the best solar installer in Los Angeles?

The highest-rated local solar company in Los Angeles is SunPower by Sun Solar-OC, with a rating of 3.00 stars.

What are the pros and cons of solar power?

The main advantages of solar power are that it can decrease or, in some cases, completely erase 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 it doesn’t work for all roof types and locations.

Is it worth installing solar panels on my roof?

Solar panels require a considerable upfront investment that costs over ten thousand dollars, but whether or not solar panels are worth it depends on a range of factors like how much you pay for electricity and how much direct sunlight your roof gets.

How often do solar panels have to be replaced?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is the amount of energy they produce will have decreased by about 0.8% each year since installing them. You can decide to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.
