Methodology: How We Ranked the Best Solar Companies in Mission Viejo

EcoWatch's solar experts analyzed each solar company in Mission Viejo 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 Mission Viejo


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 Mission Viejo

Which solar company is the best near me?

The best local solar company in Mission Viejo is SunPower by Sun Solar-OC, with a rating of 3.00 stars.

What are the advantages and disadvantages of solar power?

The main advantages of solar power are that it can reduce or, in some cases, totally eradicate your electricity bills, improve your home’s value and bring down your carbon footprint. The greatest disadvantages are that solar panels can be pricey 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.

Are solar panels worth it?

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

When should I put up solar panels?

You can put up solar panels whenever it's convenient for you, but consider doing it in the winter when the demand is less. With fewer homeowners switching to solar, you could potentially see faster installation times and more savings.
