Methodology: How We Ranked the Best Solar Companies in Vallejo

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


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 Vallejo

Solar panels run off a free energy source — the sun — but to take advantage of this you will first need to pay to install your panels.There are several factors you should consider when determining costs and your potential savings, including:

  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 0 of the project cost. Your state and even local utility companies may also have incentives and rebates that you can use. In addition, you can save about $33,000 over 20 years on your utility bills, not including incentives.
  • The amount of sunlight your area gets: Due to Vallejo’s very high amount of average daily sunlight, you should be able to save a lot on your energy bills.
  • Your income and budget: This shapes what kind of solar panels you can purchase.
  • Your current electricity bills: Solar panels can substantially decrease, or entirely eliminate, your utility bills. In Vallejo, you can save an average of $1,538 a month.

So is buying solar panels worth it? Whether you’re trying to reduce your electric bills, carbon emissions or both, solar panels are a worthwhile investment for many Vallejo homeowners.

Solar Incentives in Vallejo

If you’re thinking about making the switch to solar power, various government incentives and subsidies can drastically lower the cost of the project and expedite the return on your investment.In addition to the federal tax credit incentive, there are also some state- and city-level programs, which in the majority of cases, stack with the federal incentive, so you can save even more. In our article on solar incentives, you can see the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in Vallejo

Swapping traditional energy for solar is a powerful way to do what you can for a more environmentally-friendly future.A question many people might be asking themselves is how much can they really help the environment by going solar anyway? Something that can drastically influence your carbon footprint is how long your commute is and how much you drive overall. If you go solar and have an electric car, you can significantly decrease your carbon dioxide emissions by charging your car at home.In fact, if you install solar panels, you could reduce your carbon dioxide emissions by about 50 pounds each year. The advantages of solar power are infinite — just like solar power is! That's why so many Vallejo residents have been happy with committing to solar.

EcoWatch's Vallejo, CA Solar Company Rankings FAQs

Which solar power company is the best in Vallejo?

The top local solar company in Vallejo is SunPower, with a rating of 4.50 stars.

What are the advantages and disadvantages of solar power?

A few of the biggest pros are that it decreases your power bills, it’s environmentally friendly, and it provides a significant return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, the startup costs are high and solar panels can look clunky on your roof.

How long does it take to see a return on your investment after installing solar panels?

Solar panels usually pay for themselves in about 7.0 years, but your solar payback period will depend on your utility costs. The higher your typical power bill, the quicker your solar panel system will pay for itself.

How often do solar panels have to be replaced?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. What this means is their energy production will have decreased by about 0.8% each year since installing them. You can choose to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
