Methodology: How We Ranked the Best Solar Companies in Cupertino
EcoWatch's solar experts analyzed each solar company in Cupertino 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 Cupertino
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 Cupertino
The cost of installing a solar panel system has gone down significantly in the past several years, but it’s still a significant investment for most homeowners.The cost and possible savings vary depending on a few key factors such as:
- The type of solar panel system you can buy: This depends on how much you’re willing to invest upfront.
- Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 0 of the cost of your solar system installation from your federal taxes. In addition, not including incentives, you can save about $31,000 over 20 years on your energy bills.
- How much sunlight your roof gets: If your roof doesn’t get a lot of direct sunlight, your solar panel system won’t be able to produce as much energy, which will give you lower savings on energy bills than a roof that gets a lot of sunlight.
- Energy consumption: Installing solar panels may be too steep of an option for homes that don’t consume a good amount of energy a month.
Solar is a rewarding investment for most homeowners. You can generate your own power instead of paying for it from the grid and benefit from solar tax credits and rebates, all while helping the planet.

To increase the adoption of solar power, federal, state and local governments – and even some utility companies – offer incentives to help make switching to solar power more economically viable and accessible.Everyone can take advantage of the federal Solar Investment Tax Credit (ITC), which allows you to claim 0 of how much your solar project cost on your tax return, reducing the amount of taxes you owe that year. In addition, there may be some local incentives that can save you some extra money too. In our article on solar incentives, you can read about the incentives you qualify for in your area.
Environmental Impact of Switching to Solar in Cupertino
An important reason so many are considering adopting solar energy is to help lower their environmental impact.You may be trying to figure out – how much does making the switch help the environment anyway? The average person has a sizable carbon footprint. Between their car, which produces over 10,000 pounds of carbon dioxide emissions a year, and powering their home, it can be overwhelming to figure out what to do. Switching to solar is a practical thing you can do to help.Since solar panels don’t release greenhouse gas emissions into the atmosphere when producing electricity, they’re a good swap for nonrenewable energy sources. In fact, you could look forward to lowering your carbon dioxide emissions by about 50 pounds each year. The advantages of solar power are infinite — just like solar power is! That's why so many people have been happy with using solar energy.
