Methodology: How We Ranked the Best Solar Companies in Milpitas

EcoWatch's solar experts analyzed each solar company in Milpitas 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 Milpitas


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 Milpitas

For many homeowners, whether or not to invest in solar energy boils down to the cost. There are several factors you should take into consideration when trying to figure out costs and your potential savings, including:

  • The cost of energy for you: If your local electricity rates are quite high, there's a good chance you'll see a higher return on your investment in a solar system. In Milpitas, you can save an average of $88 a month on your electricity bills.
  • Average daily sunlight: Since Milpitas gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which impacts how much you can save on your energy bills.
  • Choice of solar panels: The kind of solar panels you are interested in getting 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 you don't need to maximize efficiency, you can opt for a higher number of more affordable panels.
  • Incentives: Those who buy and install a solar energy system this year can save 30% of their total solar spend by using the federal solar investment tax credit. You can also save about $34,000 on your electricity bills over 20 years excluding incentives.

Even though a solar panel system costs a good chunk of money upfront, it can save you a considerable amount over the lifespan of your panels. The question of how much, though, depends on a number of factors, like the size of your house and your current power bills.

Solar Incentives in Milpitas

Although a solar power system is typically a big investment, it can save you much money over time because of smaller power bills and government incentives. When you install solar panels on your home, you can take advatage of the federal tax credit, or ITC. This credit currently lowers your tax bill by 30% of the cost of your solar panels. Plus, there may often be some state and city incentives that you can benefit from to further save. Our article on solar incentives has more information on the incentives you can take advantage of in Milpitas.

Environmental Impact of Switching to Solar in Milpitas

Installing solar panels can have a meaningful impact on the environment. But how much can switching to solar actually affect the environment? A key thing to keep in mind is your overall carbon footprint. For example, if you have a long commute, your footprint may be greater, so switching to solar power for your house can help offset that. In fact, if you make the switch to solar power, you could reduce your carbon dioxide emissions by about 50 pounds each year. If you want to do what you can for the environment, you'll most likely recognize that there are many benefits of adopting solar energy other than just saving money on bills. You can also help protect the environment, which some would argue is invaluable.
