Methodology: How We Ranked the Best Solar Companies in Thornton

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


Below are some the criteria we examined specifically for Illinois 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 Thornton

We know that for lots of homeowners, the choice to invest in solar rests on installation costs. The overall price and potential savings vary depending on a few important factors such as:

  • Your location: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.
  • System size and type: Some models are more expensive than others, so the one you want to get can raise or lower your initial investment. Plus, the more solar panels you need, the more it'll cost.
  • How much you spend on energy: The typical household in Thornton shells out around $900 a year on power alone, so you could end up with that much in savings.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 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 $13,000 over the first 20 years with your system, too.

Solar is a profitable investment for most homeowners. You can make your own energy instead of paying for it from the grid and take advantage of solar incentives, all while helping protect the environment.

Environmental Impact of Switching to Solar in Thornton

There are a few key reasons why homeowners are considering solar energy: for the financial and environmental benefits. But how much can installing solar panels actually help the environment? If your home consumes lots of energy, you can impact the environment even more by switching to solar energy. While solar panel manufacturing emits carbon dioxide, the panels make up for it by considerably decreasing the amount of CO2 you would have released if you still used traditional energy. In Thornton, you can reduce your carbon footprint by 90 pounds a year with solar panels. If you want to do what you can for the environment, you'll most likely understand that there are many advantages to adopting solar energy other than just saving money on bills. You can also help preserve the environment, which some would argue is more valuable.
