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 before you can take advantage of this you will need to pay to install your panels. There are several factors you should consider when trying to determine the overall cost and how much you can save, including:
- The amount of sunlight your roof gets: If your roof doesn't see much direct sunlight, your solar panel system won't be able to make as much energy, which will give you lower savings on energy bills than someone with a roof that gets plenty of sunlight.
- Your current energy bills: Solar panels can noticeably decrease, or totally eliminate, your utility bills. In Vallejo, you can save an average of $88 a month.
- Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 30% of the cost of your solar system installation from your federal taxes. Additionally, not including incentives, you can save about $33,000 over 20 years on your energy bills.
- Choice of solar panels: The kind of solar panels you need will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.
Solar is a worthwhile investment for most homeowners. You can produce your own electricity instead of paying for it from the grid and make use of solar tax credits and rebates, all while helping protect the planet.

Environmental Impact of Switching to Solar in Vallejo
A lot of people want to do their part for the environment, which often is the chief reason for installing a solar system. Something many people might have in mind is how much can they really help save the environment by going solar anyway? The average person has a considerable carbon footprint. Between their car, which is responsible for over 10,000 pounds of carbon dioxide emissions every year, and electricity for their home, it can be overwhelming to think about what to do. Installing solar panels is a simple thing you can do to help. In fact, if you adopt solar power, you could expect to reduce your carbon dioxide emissions by about 50 pounds each year. If you care about the environment, you'll likely find that there are many benefits of adopting solar energy other than just saving money on bills. You can also help preserve the environment, which some would argue is worth more.
