Methodology: How We Ranked the Best Solar Companies in Cotati

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


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 Cotati

We know that for lots of homeowners, the choice to invest in solar comes down to installation costs. The cost and possible savings vary depending on some important factors such as:

  • Your income and budget: This determines what type of solar panels you can purchase.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Not including incentives, you can save an average of $32,000 over the first 20 years with your solar panels, too.
  • Your current electric bills: Solar panels can greatly decrease, or completely get rid of, your utility bills. In Cotati, you can save an average of $88 a month.
  • Average daily sunlight: Since Cotati gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which influences how much your electricity bills will be.

Solar is a worthwhile investment for most homeowners. You can make your own electricity instead of paying for it from a utility company and take advantage of solar incentives, all while helping the planet.

Solar Incentives in Cotati

There are many good reasons why adopting solar power is beneficial. One of them involves some government incentives that can save you money. On top of the federal tax credit incentive, there are also some state- and city-level benefits, which in almost all cases, can be claimed in addition to the federal incentive, so you can save even more. For detailed information about local incentives, see our article on solar incentives.

Environmental Impact of Switching to Solar in Cotati

An important reason so many are thinking of installing solar panels is to help reduce their environmental impact. Something many might be wondering about is how much can they really help the environment by going solar anyway? Everyone can help protect the planet by switching to solar energy, but homes that use a lot of energy will have a bigger impact. Since solar panels don't release greenhouse gas emissions into the atmosphere when creating electricity, they're a good substitute for traditional energy sources. In fact, you could look forward to lowering your carbon dioxide emissions by about 50 pounds each year. The great things about solar power are plentiful — just like solar power is! That's why so many homeowners have been happy with making the switch to solar.

EcoWatch's Cotati, CA Solar Company Rankings FAQs

Which solar power company is the best in Cotati?

In Cotati, EES Solar is the best local solar company. Our team of experts rates it 3.00 stars, so it's a good choice if you're planning on installing solar panels on your home.

What are the pros and cons of solar power?

A few of the biggest pros are that it lets you spend less on your power bills, it's environmentally friendly, 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 be an eyesore.

Are solar panels worth it?

Solar panels can be a great investment for most homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get enough sunlight or your energy bills are already fairly low, solar panels might not be for you.

How long do solar panels last?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is how much energy they produce will have decreased significantly after that point. You can decide to replace them after having them for that long or you can keep using 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.
