Methodology: How We Ranked the Best Solar Companies in Willis

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


Below are some the criteria we examined specifically for Texas 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 Willis

When deciding on a solar company, most homeowners or business owners think about the costs the most. There are quite a few factors you should take into consideration when trying to figure out the overall cost and how much you can save, including:

  • The make and model of solar panels you're thinking of getting: More high-tech panels have higher prices, so that will determine your budget for your solar project.
  • Your home's orientation toward the sun: This, along with how your roof is set up, affects affect how much electricity your solar panels can produce.
  • Typical energy usage: The more energy your household uses on average and the greater your current energy bills are, the more money you could save by going solar.
  • Incentives: Something that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that's equal to a percentage of the project cost. You can also save on your energy bills, which can result in an average of $18,000 of savings over 20 years.

Though a solar panel system costs a sizable chunk of money upfront, it can save you much more in the long term. The question of how much, though, depends on a number of factors, including the kind of solar panels you get and your current power bills.

Environmental Impact of Switching to Solar in Willis

If you're considering adding solar panels to your home, one of the major reasons why may be to lower your reliance on nonrenewable energy. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Willis, though. If your household consumes lots of energy, you can help the environment even more by switching to solar power. Because solar panels don't release CO2 emissions into the atmosphere when producing electricity, they're a good substitute for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 80 pounds each year. As you can see, trading traditional energy for solar has so many other rewards outside of saving money. One of the main ones is that you can help save the planet too.

How long do solar panels last?
