Methodology: How We Ranked the Best Solar Companies in Antioch

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


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 Antioch

For many people, the decision of which solar installer to choose comes down to costs. The cost and possible savings vary depending on a few important factors such as:

  • The type and model of solar panels you're planning on getting: More efficient models cost more, so that will affect your budget for your solar project.
  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 30% of the project cost. Your state and city may also have incentives and rebates that you can take advantage of. Plus, you can save about $33,000 over 20 years on your utility bills, not including incentives.
  • Where your home is: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.
  • How much you spend on energy: The average household in Antioch spends around $1,100 a year on power alone, so you could gain that much in savings.

Even though a solar panel system costs a sizable chunk of money upfront, it can save you a considerable amount in the long term. The question of how much, though, depends on several factors, like the amount of daily direct sunlight available and your energy consumption.

Solar Incentives in Antioch

Adopting solar power has a lot of considerable benefits. Not only can it help protect the environment, but you can also save a good amount of money on your installation with various government incentives. No matter what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will let you claim 30% of your project costs on your tax return, lowering the amount of taxes you owe that year. Additionally, there may be some state and city incentives you can benefit from too. For comprehensive information about local incentives, check out our article on solar incentives.

Environmental Impact of Switching to Solar in Antioch

If you want to add solar panels to your home, one of the major reasons why may be to reduce your carbon dioxide emissions. You may be curious — how much do solar panels help the environment anyway? A key thing to keep in mind is your overall carbon footprint. For example, if your commute is very long, your footprint may be bigger, so adopting solar energy for your house can help offset that. Although solar panel production releases carbon dioxide emissions, the panels make up for it by greatly decreasing the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In Antioch, you can reduce your carbon footprint by 50 pounds a year with solar panels. For homeowners who want to help the environment, the upfront cost of solar is a small price to pay for reducing your carbon footprint.

EcoWatch's Antioch, CA Solar Company Rankings FAQs

What is the top solar panel company in Antioch?

The best local solar company in Antioch is APG Solar, with a rating of 5.00 stars.

What are the main pros and cons of going solar?

A few of the biggest pros are that it lowers your electricity bills, it's good for the environment, and it gives you a good return on your investment (ROI). The most notable cons are that solar panels don't work as well when there's limited direct sunlight, they cost a lot upfront and solar panels can look clunky on your roof.

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

Solar panels generally pay for themselves in about 5.5 years, but your solar payback period will vary depending on your utility costs. The higher your typical electricity bill, the quicker your solar panel system will pay for itself.

What are the different kinds of solar panels?

There are three main types of solar panels: monocrystalline, polycrystalline and thin-film. In terms of efficiency and price, monocrystalline has the highest for both, then polycrystalline, and then thin-film. The best choice for you is highly influenced by the layout of your roof, how much you're willing to spend and how much energy generation you want.
