Methodology: How We Ranked the Best Solar Companies in Centennial

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


Below are some the criteria we examined specifically for Colorado 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 Centennial

For most homeowners, the decision to invest in solar energy comes down to the cost. There are quite a few factors you should take into consideration when determining costs and your potential savings, including:

  • Incentives: The federal solar investment tax credit currently lets you reduce your taxes by 30% of the project cost. Your state and even local utility companies may also have various incentives that you can benefit from. Plus, you can save about $20,000 over 20 years on your utility bills, not including incentives.
  • Your current electric bills: Solar panels can greatly lower, or completely get rid of, your utility bills. In Centennial, you can save an average of $90 a month.
  • The model of solar panels you can buy: This depends on how much you're willing to spend upfront.
  • Where your home is: This affects how much sunlight your roof gets, which helps determine how many panels you need.

Because of solar panels now being cheaper than ever as well as various solar incentives, they are a cost-effective investment for most homeowners.

Solar Incentives in Centennial

On top of the federal solar investment tax credit, there are also some local incentives, which in most cases, stack with the federal incentive, so you can save even more. For more information about local incentives, visit our article on solar incentives.

Environmental Impact of Switching to Solar in Centennial

If you're considering adding solar panels to your home, one of the main reasons why may be to lower your greenhouse gas emissions. But how much can using solar energy instead of traditional energy actually affect the environment? The amount of energy you use is a significant factor to think about. The more electricity your home uses, the greater your impact when you make the switch to solar power. When you go solar, your carbon dioxide emissions can be lowered by about 100 pounds every year. If you want to do what you can for the environment, you'll likely understand that there are many good things about adopting solar power other than just saving money on electricity. You can also help preserve the environment, which some would argue is priceless.
