Methodology: How We Ranked the Best Solar Companies in Sonoma

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


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 Sonoma

Even though solar panels can help save you a decent chunk of change on utility bills over time, it's important to know the upfront costs. There are quite a few factors you should consider when trying to determine how much it will cost and how much you can save, including:

  • Choice of solar panels: The kind of solar panels you choose will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money 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.
  • How much you spend on energy: The average household in Sonoma pays around $1,100 a year on power alone, so you could end up with that much in savings.
  • The amount of sunlight your home gets: Because of Sonoma's very high amount of average daily sunlight, you should be able to save a lot on your energy bills.
  • Incentives: Tax-paying citizens who buy and install a solar system this year can save 30% of their solar installation costs by taking advantage of the federal solar investment tax credit. You can also save about $32,000 on your energy bills over 20 years without incentives.

As a result of the cost of solar panels being lower than before as well as several solar incentives, they are a worthwhile investment for many homeowners.

Environmental Impact of Switching to Solar in Sonoma

There are tons of reasons to trade traditional energy for solar power, like saving on utility bills and helping to lower your carbon footprint. But — how much exactly can you help by using solar power?

EcoWatch's Sonoma, CA Solar Company Rankings FAQs

Which solar power company is the best in Sonoma?

The highest-rated local solar company in Sonoma is SolarCraft, with a rating of 3.00 stars.

What are some of the pros and cons of adopting solar power?

A few of the biggest pros are that it decreases your electricity bills, it's a sustainable source of energy, and it provides a decent return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, the installation cost is pricey and solar panels can be an eyesore.

Are solar panels worth it?

Solar panels require a large upfront investment that usually costs at least ten thousand dollars, but whether or not solar panels are worth it depends on a range of factors like local electricity rates and how much direct sunlight your roof gets.

What is the best kind of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can't, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and desired energy output.
