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 save you money on energy bills over time, it’s necessary to consider the startup costs.Some important things that impact the upfront cost and potential savings over time include:

  • Choice of solar panels: The kind of solar panels you need will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If you don’t need to maximize efficiency, you can go with a higher number of more affordable panels.
  • Average daily sunlight: Since San Ramon gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which influences how much your electricity bills will be.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 0 of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Aside from incentives, you can save an average of $33,000 over 20 years with your solar system, too.
  • Energy consumption: Installing a solar system may be too pricey an option for families that don’t need a good amount of energy each month.

Solar is a fruitful investment for most homeowners. You can generate your own power instead of paying for it from the grid and make use of solar tax credits and rebates, all while helping the environment.

Environmental Impact of Switching to Solar in San Ramon

Making the switch to solar power is a compelling way to do your part for a cleaner and more sustainable future.But how much can installing solar panels actually help the environment? The average person has a substantial carbon footprint. Between their car, which is responsible for over 10,000 pounds of carbon dioxide emissions each year, and electricity for their home, it can be overwhelming to figure out what to do. Going solar is a practical thing you can do to help.Although solar panel production releases carbon dioxide emissions, the panels make up for it by considerably decreasing the amount of CO2 you would have produced if you still used traditional energy.
