Methodology: How We Ranked the Best Solar Companies in Mountain View

EcoWatch's solar experts analyzed each solar company in Mountain View 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 Mountain View


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 Mountain View

Even though solar panels can save you a decent chunk of change on utility bills over time, it's necessary to take into consideration the startup costs. Some significant things that impact the cost and possible savings include:

  • How much sunlight your roof gets: If your roof doesn't get a lot of direct sunlight, your solar system won't be able to generate as much energy, which will leave you with lower savings on electricity bills than a roof that gets lots of sunlight.
  • The kind of solar panels you can buy: This is dependent on how much you're willing to invest upfront.
  • Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 30% of the project cost. Your state may also have various incentives that you can take advantage of. Additionally, you can save about $31,000 over 20 years on your utility bills, before factoring in incentives.
  • How much energy costs for you: The average family in Mountain View spends around $980 a year on power alone, so you could end up with that much in savings.

As a result of solar panels decreasing in cost as well as local and federal solar incentives, they are a solid investment for many homeowners.

Solar Incentives in Mountain View

Although installing solar panels is typically a $15,000 to $25,000 investment, it can save you much money over several years due to reduced utility bills and government incentives. You are eligible for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar system. You can also potentially use the ITC with other local incentives. Take a look at our article on solar incentives to see what incentives you can benefit from.

Environmental Impact of Switching to Solar in Mountain View

A lot of people want to do their part to help save the planet, which often is the chief motivation to install solar panels. But how much can switching to solar actually help the environment? The amount of energy you use is an important factor to keep in mind. The more power your home uses, the greater your impact when you switch to solar energy. After you go solar, your carbon footprint can be cut by about 50 pounds a year. Since solar power is abundant and produces electricity without a carbon footprint, adding solar panels to your home is one easy step you can take to help the environment.

EcoWatch's Mountain View, CA Solar Company Rankings FAQs

What is the top solar company in Mountain View?

The best local solar company in Mountain View is Clean Solar, with a rating of 4.09 stars.

Are solar panels actually eco-friendly?

Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Solar panel manufacturing needs 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 5.8 years, but the exact period varies by local electricity costs, incentives and net metering programs.

How much solar panel capacity do I need for my house?

Solar panel capacity is rated based on how many watts of power they generate under standard testing conditions. Since each panel can usually produce about 250 to 400 watts per hour, the average household will need 20 to 35 panels.
