Methodology: How We Ranked the Best Solar Companies in Orange

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


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 Orange

When choosing a solar company, most homeowners or business owners think about the costs above all.Some important things that influence the upfront cost and potential savings over time include:

  • Average daily sunlight: Since Orange gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which influences how much your electricity bills will be.
  • Choice of solar panels: The type of solar panels you are interested in getting will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If you don’t need to maximize efficiency, you can opt for a higher number of more affordable panels.
  • Incentives: The federal solar investment tax credit, which can save you some money, allows you to deduct 0 of the cost of your solar system installation from your federal taxes. Plus, not including incentives, you can save about $26,000 over 20 years on your energy bills.
  • How much you spend on energy: The average family in Orange pays around $1,200 a year on energy alone, so you could end up with that much in savings.

Solar is a fruitful investment for most homeowners. You can produce your own electricity instead of paying for it from the grid and make use of solar incentives, all while helping the Earth.

Environmental Impact of Switching to Solar in Orange

If you’re thinking of adding solar panels to your home, one of the primary reasons why may be to lower your carbon footprint.You may be asking yourself – how much do solar panels do for the planet anyway? Regardless of your location, you can help the planet by switching to solar energy, but homes that use a lot of energy will have a bigger impact.In fact, if you install solar panels, you could reduce your carbon dioxide emissions by about 50 pounds each year. If you care about the environment, you’ll most likely find that there are many benefits of adopting solar power other than just saving money on bills. You can also help protect the environment, which some would argue is more valuable.
