Methodology: How We Ranked the Best Solar Companies in Williams

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


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 Williams

For many people, the decision of which solar company to go with depends on costs. There are quite a few factors you should take into consideration when determining costs and your potential savings, such as:

  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, lets you deduct 30% of the cost of installing your solar panel system from your federal taxes. Plus, not including incentives, you can save about $32,000 over 20 years on your energy bills.
  • Your location: This affects how much sunlight your roof receives, which helps determine how many panels you need.
  • The model of solar panel system you can purchase: This hinges on how much you're willing to spend upfront.
  • How much you spend on energy: If your local utility rates are quite high, there's a good chance you'll have a higher return on your investment in solar panels. In Williams, you can save an average of $88 a month on your electricity bills.

Although a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on several factors, including the size of your house and incentives.

Solar Incentives in Williams

Switching to solar power has lots of great benefits. Not only can it help preserve the Earth, but you can also save a decent amount of money on your installation with various government incentives. On top of the federal tax credit incentive, there are also some local incentives, which in most cases, can be claimed in addition to the federal incentive, so you get to save even more. In our article on solar incentives, you can read about the incentives you qualify for in Williams.

Environmental Impact of Switching to Solar in Williams

An important reason so many people consider switching to solar power is to help bring down their environmental impact. But how much can switching to solar actually affect the environment? The average person has a considerable carbon footprint. Between their car, which releases over 10,000 pounds of carbon dioxide emissions every year, and energy for their home, it can be overwhelming to think about what to do. Installing solar panels is one of the easiest things you can do to help. In fact, if you install solar panels, you could expect to reduce your carbon dioxide emissions by about 50 pounds each year. The advantages of solar power are plentiful — just like solar power is! That's why so many Williams residents have been happy with making the switch to solar.
