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 readers, the decision of which solar installer to choose comes down to how much it’ll cost.Some significant things that determine how much it will cost and how much you could save include:

  • Your location: This affects how much sunlight your roof receives, which helps determine how many panels you need.
  • The model of solar panels you’re planning on getting: More efficient panels are more expensive, 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 0 of the project cost. Your state and city may also have incentives and rebates that you can benefit from. In addition, you can save about $32,000 over 20 years on your utility bills, without incentives.
  • Typical energy usage: The more energy your home consumes on average and the steeper your current electricity bills are, the more money you could save by going solar.

So is a solar panel system worth it? Whether you want to lower your energy bills, carbon dioxide emissions or both, solar panels are a great investment for many Williams homeowners.

Solar Incentives in Williams

Because solar power is better for the environment than fossil fuels, there are several government incentives in place to encourage its adoption.State and city solar incentive programs depend on the location and, sometimes, utility company. Many states offer rebates for home solar power systems, in addition to the federal solar tax credit. You can find out about the incentives you can take advantage of in our article on solar incentives

Environmental Impact of Switching to Solar in Williams

One of the most compelling reasons to tap into solar energy is to reduce your dependence on traditional energy sources like burning fossil fuels, which are damaging for the environment.Something many might be wondering about is how much can they really help preserve the environment by switching to solar power anyway? A significant thing to think about is your overall carbon footprint. For example, if you have a long commute, your footprint may be larger, so adopting solar power for your house can help offset that.In fact, if you install solar panels, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. As you can see, trading traditional energy for solar has so many other perks besides saving money. One of the most important ones is that you can help save the planet too.

Which solar panel installer is the best in Williams?

In Williams, Sunrun Solar is the most reputable local solar company. Our team of experts rates it 3.00 stars, so it's a great choice if you're looking to add solar panels to your home.

What are the pros and cons of solar power?

The greatest advantages of solar power are that it can lower or, for some, 100% erase your electricity bills, improve your home’s value and cut back on your carbon footprint. The biggest disadvantages are that solar panels can be costly to install, you may not save as much if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.

Are solar panels worth it?

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

How efficient are solar panels?

Solar panel efficiency is the amount of solar energy that is converted into electricity. Most panels today have an efficiency rating of about 15 to 25%. If your panels are more efficient, you'll need less of them for your home's energy needs.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
