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
Solar panels run off a free energy source — the sun — but before you can take advantage of this you will need to pay to install your system. Some key things that impact how much it will cost and how much you could save include:
- Your household's power bills: Based on the high monthly electricity bills in Cupertino, you could save about $960 a year with solar.
- Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 30% of the project cost. Your state and city may also have various incentives that you can use. Plus, you can save about $31,000 over 20 years on your utility bills, not including incentives.
- Your income and budget: This affects what kind of solar panels you can buy.
- The amount of sunlight your area gets: Because of Cupertino's very high amount of average daily sunlight, you should be able to save a lot on your electricity bills.
There are several wonderful benefits of solar even with the initial cost of installation. It can help the planet and your bank account. In addition, it can boost the value of your home, resulting in even more benefits if you choose to sell your home later.

EcoWatch's Cupertino, CA Solar Company Rankings FAQs
Which solar installation company is the best in Cupertino?
The best local solar company in Cupertino is Clean Solar, with a rating of 4.09 stars.
What are a few of the pros and cons of adopting solar power?
The main 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 main disadvantages are that solar panels can be pricey 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.
Is it worth installing solar panels on my house?
Solar panels need a significant upfront investment that costs over ten thousand dollars, but whether or not solar panels are worth it depends on a collection of factors like how much you pay for electricity and how much direct sunlight your roof gets.
What are the different kinds 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 cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can't, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and how much efficiency you're looking for.
