Methodology: How We Ranked the Best Solar Companies in Los Altos Hills

EcoWatch's solar experts analyzed each solar company in Los Altos 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 Los Altos 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 Los Altos Hills

We get that for many homeowners, the decision to invest in solar rests on installation costs.Some main factors that dictate the cost of installing solar panels on your home and how much it could save you over time include:

  • Your income and budget: This determines what type of solar panels you can purchase.
  • The amount of sunlight your rooftop gets: Due to Los Altos Hills’s very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 0 of the cost of installing your solar panel system from your taxes. In addition, not including incentives, you can save about $32,000 over 20 years on your energy bills.
  • How much electricity your household consumes: Households that need plenty of energy each month may call for more solar panels and, consequently, more upfront cost, but will also benefit more over time.

Even though a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars over the lifespan of your panels. The question of how much, though, depends on a number of factors, like the size of your solar panel system and your energy consumption.

EcoWatch's Los Altos Hills, CA Solar Company Rankings FAQs

Which solar company is the best in Los Altos Hills?

The top local solar company in Los Altos Hills is SunPower Corporation, with a rating of 4.50 stars.

What are the pros and cons of solar power?

The greatest advantages of solar power are that it can reduce or, in some cases, completely cut your electricity bills, improve your home’s value and bring down your carbon footprint. The greatest disadvantages are that solar panels can be costly to install, you may not save a lot if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.

Are solar panels worth it?

Solar panels can be a fruitful investment for many homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get enough sunlight or your electricity bills are already fairly low, solar panels might not be for you.

What are the different types of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types 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.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
