Methodology: How We Ranked the Best Solar Companies in Dardenne Prairie

EcoWatch's solar experts analyzed each solar company in Dardenne Prairie 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 Dardenne Prairie


Below are some the criteria we examined specifically for Missouri 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 Dardenne Prairie

  • Your home's orientation toward the sun: This, along with your roof configuration, affects affect how much electricity your solar panels can make.
  • Energy consumption: Installing solar panels may be an expensive investment for households that don’t need a good amount of energy each month.
  • The cost of energy for you: If your local power rates are quite high, there's a good chance you'll have a higher return on your investment in a solar panel system. In Dardenne Prairie, you can save an average of $1,291 a month on your electricity bills.

Environmental Impact of Switching to Solar in Dardenne Prairie

One of the most compelling reasons to embrace solar power is to cut your dependence on traditional energy sources like burning fossil fuels, which are damaging for the environment.But how much can switching to solar actually help the environment?

For example, if you spend a lot of time driving to work, your footprint may be greater, so adopting solar power for your home can help offset that.Since solar panels don’t release greenhouse gas emissions into the atmosphere when producing electricity, they’re a good substitute for nonrenewable energy sources.

You can also help protect the environment, which some would argue is more valuable.
