Methodology: How We Ranked the Best Solar Companies in Costa Mesa

EcoWatch's solar experts analyzed each solar company in Costa Mesa 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 Costa Mesa


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 Costa Mesa

For many readers, the decision of which solar installer to choose depends on how much it'll cost. Some important things that impact how much it will cost and how much you could save include:

  • The type of solar panels you want to get: Some are more expensive, so that will affect your budget for your solar project.
  • Your city: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
  • How much energy you use: If your family uses a lot of energy, you'll benefit more from installing solar panels.
  • Incentives: One thing that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save on your utility bills, which can generate an average of $25,000 of savings over 20 years.

There are many good benefits of solar even with the initial cost of installation. It can help the environment and your finances. Plus, it can raise the value of your home, resulting in even more benefits if you want to sell your home later.

EcoWatch's Costa Mesa, CA Solar Company Rankings FAQs

What is the top solar installer in Costa Mesa?

In Costa Mesa, Renewable USA is the most reputable local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're looking to add solar panels to your house.

What is the negative environmental impact of solar panel manufacturing?

Manufacturing solar panels requires chemicals and produces toxic waste that can be harmful for the environment, which is the main downside of solar panels.

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

Solar panels generally pay for themselves in about 7.3 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 pay for itself.

How often do solar panels need to be replaced?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is their energy production will have decreased significantly after that point. You can decide 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.
