Methodology: How We Ranked the Best Solar Companies in Rancho Cucamonga

EcoWatch's solar experts analyzed each solar company in Rancho Cucamonga 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 Rancho Cucamonga


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 Rancho Cucamonga

The cost of installing solar panels has dropped significantly in the past few years, but it's still a significant investment for most homeowners. Some key factors that affect how much it will cost to install a solar panel system on your home and how much it could save you over time include:

  • The amount of sunlight your roof gets: If your rooftop doesn't see much direct sunlight, your solar system won't be able to generate as much energy, which will leave you with lower savings on power bills than a roof that gets lots of sunlight.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 30% of your total installation cost, your local government may offer additional tax exemptions, credits or rebates that can help you save even more. Aside from incentives, you can save an average of $25,000 over 20 years with your solar system, too.
  • Your income and budget: This shapes what kind of solar panels you can get.
  • Your home's power bills: Due to high monthly power bills in Rancho Cucamonga, you could save about $750 a year with solar.

Solar is a valuable investment for most homeowners. You can make your own power instead of paying for it from a utility company and take advantage of solar incentives and rebates, all while helping the environment.

EcoWatch's Rancho Cucamonga, CA Solar Company Rankings FAQs

Which solar company is the best in Rancho Cucamonga?

The highest-rated local solar company in Rancho Cucamonga is Renewable USA, with a rating of 5.00 stars.

What is the negative environmental impact of solar panel manufacturing?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Solar panel manufacturing uses a lot of energy as well. The energy payback period is about 1 to 4 years.

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

The average payback period for solar panel installation is about 7.3 years, but the exact period varies depending on local electricity costs, incentives and net metering programs.

What are the different kinds of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can't, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and how much efficiency you're looking for.
