Methodology: How We Ranked the Best Solar Companies in San Ramon

EcoWatch's solar experts analyzed each solar company in San Ramon 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 San Ramon


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 San Ramon

Even though solar panels can help save you a decent chunk of change on energy bills over time, it’s important to consider the upfront costs.The overall price and potential savings vary depending on some key factors such as:

  • System size and type: Some models are more costly than others, so the one you choose can raise or lower your upfront cost. Plus, the more solar panels you need, the more it'll cost.
  • The amount of sunlight your house gets: Due to San Ramon’s very high amount of average daily sunlight, you should be able to save a lot on your electricity bills.
  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 0 of the project cost. Your state may also have various incentives that you can benefit from. Additionally, you can save about $33,000 over 20 years on your utility bills, without incentives.
  • Energy consumption: Installing a solar system may be too pricey an option for homes that don’t consume too much energy per month.

Though a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on several factors, such as the amount of daily direct sunlight available and your local electricity rates.

Solar Incentives in San Ramon

To increase the adoption of solar power, federal, state and local governments – and even some utility companies – offer incentives to help make going solar more financially viable and accessible.Everyone can take advantage of the federal Solar Investment Tax Credit (ITC), which will allow you to claim 0 of how much your solar project cost when you file taxes, reducing the amount of taxes you owe that year. Plus, there may be some state and city incentives that can save you some extra money too. In our article on solar incentives, you can find out about the incentives you qualify for near you.

Environmental Impact of Switching to Solar in San Ramon

One of the most compelling reasons to adopt solar energy is to decrease your reliance on traditional energy sources like burning fossil fuels, which are damaging for the environment.You may be curious – how much does making the switch help the environment anyway? One thing that can dramatically affect your carbon footprint is your commute time and how much you drive in general. If you go solar and drive an electric car, you can vastly cut back on your carbon dioxide emissions by charging your car at home.In fact, if you install solar panels, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. Since solar energy is plentiful and produces electricity without releasing carbon emissions, installing solar panels is one easy step you can take to help the environment.
