Methodology: How We Ranked the Best Solar Companies in Duarte

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


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 Duarte

The cost of installing solar panels has gone down significantly over the past few years, but it’s still a large investment for most homeowners.There are quite a few factors you should consider when trying to determine how much it will cost and how much you can save, such as:

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 0 of your total installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Excluding incentives, you can save an average of $25,000 over 20 years with your system, too.
  • The kind of solar panels you’re thinking of getting: Higher-efficiency panels are more expensive, so that will shape your budget for your solar project.
  • Your location: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
  • How much you spend on energy: The typical family in Duarte shells out around $1,200 a year on electricity alone, so you could gain that much in savings.

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

EcoWatch's Duarte, CA Solar Company Rankings FAQs

Which solar installation company is the best in Duarte?

In Duarte, SunPower by True Power Solar is the most reputable local solar company. Our team of experts rates it 3.00 stars, so it's a solid choice if you're looking to add solar panels to your roof.

What are some of the advantages and disadvantages of going solar?

The greatest advantages of solar power are that it can decrease or, for some, completely cut your electricity bills, raise the value of your home and lower your carbon footprint. The biggest disadvantages are that solar panels can be expensive 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.

How long does it take to see a return on your investment after installing solar panels?

Solar panels generally pay for themselves in about 9.1 years, but your solar payback period will vary based on your utility costs. The higher your typical energy bill, the quicker your solar panel system will pay for itself.

When should I install solar panels?

Despite summer being the most common time people install solar panels, the perfect time is actually winter. You can save money since there's less demand during the winter months, and it allows you to be up and running with solar for the more expensive power bills you may get during the summer.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
