Methodology: How We Ranked the Best Solar Companies in Los Gatos

EcoWatch's solar experts analyzed each solar company in Los Gatos 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 Los Gatos


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 Los Gatos

We get that for lots of homeowners, the choice to invest in solar comes down to installation costs.The overall price and potential savings vary depending on a few important factors such as:

  • Incentives: The federal solar investment tax credit currently lets you lower your taxes by 0 of the project cost. Your state may also have incentives and rebates that you can take advantage of. Plus, you can save about $33,000 over 20 years on your utility bills, not including incentives.
  • Choice of solar panels: The type of solar panels you choose will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.
  • Where your home is: This affects how much sunlight your roof gets, which helps determine how many panels you need.
  • Electricity consumption: The average household in Los Gatos doesn’t use much energy, and so may not see as many savings on their power bills.

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

Many want to do their part to help protect the environment, which in many cases is the primary motivation to install a solar system.Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Los Gatos, though. Switching to solar power is a sustainable choice for the environment, due to the fact that the biggest source of greenhouse gas emissions in the U.S. is from burning fossil fuels for electricity, heat, and transportation – all of which can be powered by solar instead.While solar panel manufacturing releases carbon dioxide emissions, the panels make up for it by considerably reducing the amount of CO2 you would have produced if you still used traditional energy. In Los Gatos, you can reduce your carbon footprint by 50 pounds a year with solar panels. Since solar power is plentiful and generates electricity without CO2 emissions, making the switch to solar power is one easy step you can take to help protect the planet.

EcoWatch's Los Gatos, CA Solar Company Rankings FAQs

Which solar installation company is the best in Los Gatos?

In Los Gatos, SunPower is the top local solar company. Our team of experts rates it 4.50 stars, so it's a good choice if you're planning on installing solar panels on your house.

What are the pros and cons of solar power?

A few of the biggest pros are that it lets you spend less on your electricity bills, it’s a sustainable source of energy, and it can give you a significant return on your investment (ROI). The most notable cons are that solar panels don’t produce electricity at night, the installation cost is pricey and solar panels can look clunky on your roof.

Is it worth installing solar panels on my home?

Solar panels can be a good investment for a majority of homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your power bills are already fairly low, solar panels might not be for you.

How long do solar panels last?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of. What this means is their energy production will have decreased by about 0.8% each year since installing them. You can opt to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
