Methodology: How We Ranked the Best Solar Companies in San Gabriel

EcoWatch's solar experts analyzed each solar company in San Gabriel 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 San Gabriel


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 San Gabriel

When picking a solar company, most homeowners or business owners wonder about the costs the most.Some important factors that influence how much it will cost to install solar panels on your home and how much money you could save over time are:

  • The type of solar panel system you can buy: This depends on your income and budget.
  • Incentives: The federal solar investment tax credit, which can save you some money, lets you deduct 0 of the cost of your solar system installation from your taxes. Additionally, not including incentives, you can save about $25,000 over 20 years on your energy bills.
  • How much you spend on energy: The average household in San Gabriel spends around $1,200 a year on energy use alone, so you could end up with that much in savings.
  • Your location: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.

Solar is a fruitful investment for most homeowners. You can make your own power instead of paying for it from the grid and take advantage of solar incentives and rebates, all while helping protect the planet.

Environmental Impact of Switching to Solar in San Gabriel

One of the most compelling reasons to tap into solar power is to decrease your dependence on traditional energy sources like burning fossil fuels, which are damaging for the environment.You may be asking yourself – how much does making the switch do for the planet anyway? If your household uses a lot of energy, you can have an even greater impact on the planet by switching to solar energy.Because solar panels don’t release CO2 emissions into the atmosphere when creating electricity, they’re a good swap for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. For those who care about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.
