Methodology: How We Ranked the Best Solar Companies in Livermore

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


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 Livermore

Solar Incentives in Livermore

If you’re thinking about making the switch to solar power, various government incentives and state programs can drastically lower your project costs and expedite the return on your investment.You qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your solar panels. You can also possibly use the ITC with other state and city rebates and benefits. In our article on solar incentives, you can find out about the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in Livermore

An important reason so many are considering adopting solar energy is to help lower their environmental impact.But how much can using solar energy instead of traditional energy actually help the environment? In a city like Livermore where commute times can be very long, going solar can help help reduce the carbon footprint of driving.Since solar panels don’t release carbon dioxide emissions into the atmosphere when producing electricity, they’re a good substitute for nonrenewable energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 50 pounds each year. As you can see, using solar power has so many other perks outside of saving money. One of the major ones is that you can help save the planet too.

Which solar company is the best in Livermore?

In Livermore, SunPower is the most reputable local solar company. Our team of experts rates it 4.50 stars, so it's a great choice if you're planning on installing solar panels on your house.

What is the negative environmental impact of making solar panels?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Solar panel manufacturing requires a lot of energy as well. The energy payback period is about 1 to 4 years.

Is it worth putting solar panels on my roof?

Solar panels can be a fruitful investment for a majority of homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get enough sunlight or your power bills are already reasonably low, solar panels might not be for you.

What is solar panel capacity and how much do I need for my house?

Solar panel capacity is rated depending on how much power they generate under standard testing conditions. Since each panel can generally produce about 250 to 400 watts per hour, the average household will need 20 to 35 panels.
