Methodology: How We Ranked the Best Solar Companies in Granite Hills

EcoWatch's solar experts analyzed each solar company in Granite Hills 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 Granite Hills


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 Granite Hills

For many people considering switching to solar, the decision of which solar company to hire depends on pricing.Some key factors that affect the cost of installing solar panels on your home and how much it could save you over time include:

  • The model of solar panel system you can purchase: This is dependent on how much you’re willing to spend upfront.
  • Your current power bills: Solar panels can noticeably decrease, or entirely eradicate, your utility bills. In Granite Hills, you can save an average of $1,659 a month.
  • How much sunlight your roof gets: If your rooftop doesn’t see much direct sunlight, your solar panels won’t be able to generate as much energy, which will leave you with lower savings on electricity bills than a roof that gets a lot of sunlight.
  • Your energy consumption: If your household uses a lot of energy, you'll reap more rewards from going solar.
