Methodology: How We Ranked the Best Solar Companies in Santa Clara

EcoWatch's solar experts analyzed each solar company in Santa Clara 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 Santa Clara


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 Santa Clara

For many people, the decision of which solar company to choose comes down to total costs. There are quite a few factors you should consider when determining the overall cost and how much you can save, including:

  • How much energy costs for you: The average household in Santa Clara shells out around $940 a year on energy alone, so you could gain that much in savings.
  • Your income and budget: This shapes what kind of solar panels you can get.
  • How much sunlight your roof gets: This, plus how your roof is set up, affects affect how much electricity your solar panels can generate.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 30% 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. Not including incentives, you can save an average of $30,000 over 20 years with your solar system, too.

So are solar panels worth it? Whether you'd like to lower your electric bills, carbon dioxide emissions or both, solar panels are a worthwhile investment for many Santa Clara homeowners.

Solar Incentives in Santa Clara

To increase the adoption of solar power, incentives are offered by the government — and even some utility companies — to help make solar more affordable and accessible. Regardless of where you live, you can take advantage of the federal Solar Investment Tax Credit (ITC), which allows you to claim 30% of how much you paid for your solar installation on your tax return, reducing the amount of taxes you owe that year. Additionally, there may be some local incentives that stack with the ITC too. In our article on solar incentives, you can read about the incentives you qualify for near you.

Environmental Impact of Switching to Solar in Santa Clara

One of the most compelling reasons to tap into solar energy is to reduce your dependence on traditional energy sources like burning fossil fuels, which are damaging for the environment. You may be trying to figure out — how much does going solar help the planet anyway? In a city like Santa Clara where commute times can be pretty long, installing solar panels can help help reduce the carbon footprint of driving. In fact, if you adopt solar power, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. For people who want to help the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.

What is the most reputable solar installation company in Santa Clara?

The highest-rated local solar company in Santa Clara is APG Solar, with a rating of 5.00 stars.

What is the negative environmental impact of making solar panels?

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

How long does it take for solar to pay for itself?

The average payback period for solar panel installation is about 6.1 years, but the exact period varies by the cost of electricity where you are, incentives and net metering programs.

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 decreased 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.
